Atomic Energy Exercises - Assignment Example An approximation of the distance of separation for curve 2 appears to be bigger than that of curve 1 thus accounting for the smaller energy than that of curve 1. The maximum amount of force that is needed to push the particles together is greater in curve 1 than in curve 2. This is because the vector force that pulls particles towards each other is inversely proportional to the square of the separation distance and directly proportional to the products of the two charges. Case 2 There is immense proton repulsion between the protons within the nucleus because of the Coulomb’s law electrostatic interactions. In this regard, the force that is exerted by the center protons towards the outer protons is inversely proportion to the proton’s square of the separation distance. The separation distance squared comes about because the force field of an isolated proton charge is uniform towards all directions and becomes diluted with the separation distance just like the area of the centered sphere of the point charge which increases as its radius increases. Case 3 For the incoming protons, their potential energy is smaller compared to when they reach the bottom pit in the center. From Coulomb’s law (f=kq1q2/r2), potential energy is the product of force and distance which is given by PE= kq1q2/r. This means that as the protons move from outside they are far apart from each other hence remarkably little potential energy. When protons are in the center, the particles are close to each other leading to a small separation distance thus a greater potential energy compared to that of incoming protons. Case 4 Binding energy is the mechanically required energy to disassemble an atom into nucleus and free electrons (Jones International University, 2011). Helium has a lower binding energy compared to beryllium and iron. This is because helium has an atomic mass of 2, beryllium has an atomic mass of 4, whereas iron has an atomic mass of 26. In this case, iron has the greatest binding energy because of its atomic mass that is larger than that of beryllium and helium. This is so because, from the periodic table (of elements), the elements with greater atomic mass have increasing binding energy than those with a small atomic mass up to elements that are heavier than xenon which do not obey this trend. This is due to the increasing nucleon force in the nucleus as an extra nucleon gets attracted to other nucleons making the nucleus to be tightly bound. On the other hand, the amount of energy needed to pull the nuclei together for a tight bound is less for in an iron atom than the beryllium and helium atom. This is due to the fact that iron atom has a larger atomic mass than the helium and beryllium atoms. The larger the atomic mass, the more the energy levels of an atom and the less the energy needed to push the nucleus together for a tight bound. Case 5 Uranium 238 has 92 protons and 146 neutrons. Its binding energy can be given by: a - b /A1/3 - cZ2/A4/3- d (N-Z) 2 /A2 Â ± e/A7/4. Where a = 14.0, b = 13.0, c = 0.585, d= 19.3, and e = 33. A is the number of nucleons, Z is the number of protons in the nucleus, and N is the number of neutrons in the nucleus. B.E/A = 14-13/238^1/3- 0.585x92^2/238^4/3 – 19.3 (146-92) ^2/238^2Â ± 33/238^7/4 = 0.1614-3.357-0.9936 Â ±0.002288 =-4.1892

Flip Flop Circuit Explanation and Study

Flip Flop Circuit Explanation and Study A flip-flop is a term referring to an electronic circuit (a bistable multivibrator) that has two stable states and thereby is capable of serving as one bit of memory. Today, the term flip-flop has come to mostly denote non-transparent (clocked or edge-triggered) devices, while the simpler transparent ones are often referred to as latches; however, as this distinction is quite new, the two words are sometimes used interchangeably . A flip-flop is usually controlled by one or two control signals and/or a gate or clock signal. The output often includes the complement as well as the normal output. As flip-flops are implemented electronically, they require power and ground connections. Introduction Basic Flip-Flop Circuit A flip-flop circuit can be constructed from two NAND gates or two NOR gates. Each flip-flop has two outputs, Q and Q, and two inputs, set and reset. This type of flip-flop is referred to as an SR flip-flop or SR latch. The flip-flop in figure has two useful states. When Q=1 and Q=0, it is in the set state (or 1-state). When Q=0 and Q=1, it is in the clear state (or 0-state). The outputs Q and Q are complements of each other and are referred to as the normal and complement outputs, respectively. The binary state of the flip-flop is taken to be the value of the normal output. When a 1 is applied to both the set and reset inputs of the flip-flop in Figure 2, both Q and Q outputs go to 0. This condition violates the fact that both outputs are complements of each other. In normal operation this condition must be avoided by making sure that 1s are not applied to both inputs simultaneously. The NAND basic flip-flop circuit in figure operates with inputs normally at 1 unless the state of the flip-flop has to be changed. A 0 applied momentarily to the set input causes Q to go to 1 and Q to go to 0, putting the flip-flop in the set state. When both inputs go to 0, both outputs go to 1. This condition should be avoided in normal operation. Master-Slave Flip-Flop Introduction A master-slave flip-flop is constructed from two seperate flip-flops. One circuit serves as a master and the other as a slave. The logic diagram of an SR flip-flop is shown in figure.The master flip-flop is enabled on the positive edge of the clock pulse CP and the slave flip-flop is disabled by the inverter. The information at the external R and S inputs is transmitted to the master flip-flop. When the pulse returns to 0, the master flip-flop is disabled and the slave flip-flop is enabled. The slave flip-flop then goes to the same state as the master flip-flop. In addition to these two flip-flops, the circuit also includes an inverter. The inverter is connected to clock pulse in such a way that the inverted CP is given to the slave flip-flop. For example, if the CP=0 for a master flip-flop, then the output of the inverter is 1, and this value is assigned to the slave flip-flop. In other words if CP=0 for a master flip-flop, then CP=1 for a slave flip-flop. A master-slave flip flop can be constructed using any type of flip-flop which forms a combination with a clocked RS flip-flop, and with an inverter as slave circuit. An RS master-slave flip-flop consists of two RS flip-flops; one is the master flip-flop and the other a slave. The inverted CP is given to the slave flip-flop. Now when CP=0, the master flip-flop is disabled. So the external inputs R and S of the master flip-flop will not affect the circuit until CP goes to 1. The inverter output goes to 1 and it enables the slave flip-flop. The output Q=Y and Q=Y. When CP=1, the master flip-flop is enabled and the slave flip-flop remains isolated from the circuit until CP goes back to 0. Now Y and Y depends on the external inputs R and S of the master flip-flop. Assume that the flip-flop is in a clear state and no clock pulse is applied to the circuit. The external inputs given are S=1 and R=0. This input will not affect the state of the system until the CP=1. Now the next clock pulse applied should change the state to SET state (S=1, R=0). During the clock pulse transition from 0 to 1, the master flip-flop goes to set state and changes the output Y to 1. However this does not affect the output of the system since the slave flip-flop is isolated from the system (CP=0 for slave). So no change is observed at the output of the system. When the CP returns to 0, the master flip-flop is disabled while the slave is enabled. So the information from the master is allowed to pass through to the slave. Since Y=1, this changes the output Q to 1. In a master slave flip-flop it is possible to change the output of the flip-flop and the external input with same clock pulse. This is because the external input S can be changed at the same time while the pulse goes through its negative edge transition. When CP=0, change in external input S would not affect the state of the system. From this behavior of the master slave flip-flop it is quite clear that the state change in flip-flops coincide with the negative edge transition of the pulse. Negative edge transition means an inverter is attached between the CP terminal and the input of the slave. In positive edge triggered master slave flip-flops an additional inverter is attached between the CP terminal and the input of the master. Such flip-flops are triggered with negative pulses. Negative edge of the pulse affects the master and positive edge affects the slave. Timing Diagram The timing relationship is shown in figure and is assumed that the flip-flop is in the clear state prior to the occurrence of the clock pulse. The output state of the master-slave flip-flop occurs on the negative transition of the clock pulse. Some master-slave flip-flops change output state on the positive transition of the clock pulse by having an additional inverter between the CP terminal and the input of the master. Let us say that a clock of certain frequency is fed to the FF, and consider the case of JK being 11. The propagation delay of FF is very very less than the clock pulse time.The FF continues complementing the output an unpredictable number of times, thus leading to anomaly in the final output after the pulse time of the clock is completed.At the end the clock pulse, the value of O is uncertain.This continuous toggling of output when clock is HIGH is known asRace Around condition. This can be eliminated by Clock time should be less than the propagation delay time of the latch. By using Masterslave JK Flip flop. Pulse-Triggered Master-Slave These flip-flops are constructed from two separate flip-flops. The term pulse-triggered means that data are entered into the flip-flop on the leading edge of the clock pulse, but the output does not reflect the input state until the trailing edge of the clock pulse. This is due to the master flip-flop being rising edge triggered and the slave flip-flop being falling edge triggered as illustrated in the figure below. Master-Slave J-K Flip-Flop A master slave flip flop is a cascade of two S R flip flops with feedback from the outputs of the second to the inputs of the first. Positive clock pulses are applied to the first flip flop and clock pulses are inverted before these are applied to the second flip flop. The logic symbol for the master-slave flip-flop only indicates the initial inputs to the master and the outputs from the slave as indicated by the J-K master-slave flip-flop shown in figure Operation of master-slave J-k flip flop Whe CK=1, the first flip flop is enabled and the outputs Q and Q(toggle) respond to the J K according to its truth table.At this time the second flip flop is inhibited because its clock is LOW. When CK goes LOW, the first flip flop is inhibited and the second flip flop is enabled, because now its clock isHIGH.Since the second flip flop simply follows the first one it is referred to as slave and he first one as the master. Master-slave D flip-flop Consider the following terms: RIPPLE THROUGH: An input changes level during the clock period, and the change appears at the output. PROPAGATION DELAY: The time between applying a signal to an input, and the resulting change in the output. These problems can be overcome by masterslave D Flip flop. A master-slave D flip-flop is created by connecting two gated D latches in series, and inverting the enable input to one of them. It is called master-slave because the second latch in the series only changes in response to a change in the first (master) latch. The term pulse-triggered means that data is entered on the rising edge of the clock pulse, but the output does not reflect the change until the falling edge of the clock pulse. It responds on the negative edge of the enable input usually a clock. For a positive-edge triggered master-slave D flip-flop, when the clock signal is low (logical 0) the enable seen by the first or master D latch (the inverted clock signal) is high (logical 1). This allows the master latch to store the input value when the clock signal transitions from low to high. As the clock signal goes high (0 to 1) the inverted enable of the first latch goes low (1 to 0) and the value seen at the input to the master latch is locked. Nearly simultaneously, the twice inverted enable of the second or slave D latch transitions from low to high (0 to 1) with the clock signal. This allows the signal captured at the rising edge of the clock by the now locked master latch to pass through the slave latch. When the clock signal returns to low (1 to 0), the output of the slave latch is locked, and the value seen at the last rising edge of the clock is held while the master latch begins to accept new values in preparation for the next rising clock edge. By removing the leftmost inverter in the above circuit, a D-type flip flop that strobes on the falling edge of a clock signal can be obtained. The truth table obtained is as follows: CONVENTIONS: The circuit is set means output = 1 The circuit is reset means output = 0 Flip-flops have two output Q and Q or (Q and Q) Due to time related characteristic of the flip-flop, Q and Q (or Q) are usually represented as followed: Qt or Q: present state Qt+1 or Q+: next state POINTS TO REMEMBER: When using a real flip-flop, the following information is needed to be considered: propagation delay (tpLH, tpHL) time needed for an input signal to produce an output signal minimum pulse width (tw(min)) minimum amount of time a signal must be applied setup and hold time (tsu, th) minimum time the input signal must be held fixed before and after the latching action. USES: A flip-flop is used to store one bit, or binary digit, of data. Any one of the flip-flop types can be used to build any of the others. Many logic synthesis tools will not use any other type than D flip-flop and D latch. Level sensitive latches cause problems with Static Timing Analysis (STA) tools and Design For Test (DFT). Many FPGA devices contain only edge-triggered D flip-flops The data contained in several flip-flops may represent the state of a sequencer, the value of a counter, an ASCII character in a computers memory or any other piece of information. One use is to build finite state machines from electronic logic. The flip-flops remember the machines previous state, and digital logic uses that state to calculate the next state. Frequency division: a chain of T flip-flops as described above will also function to divide an input in frequency by 2n, where n is the number of flip-flops used between the input and the output. Master Slave Flip Flop is useful in eliminating race around condition. They are used in both asynchronous and clocked sequential systems.

Air pollution has become a major public health issues and it harms both human health and the environmental, over time in Europe air pollution have decrease greatly (EEA 2013), and this air pollutants include carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), particulate matter (PM), sulfur dioxide (SO2) and also lead (pb) (WHO 2011), particulate matter and Ozone are now been identify as the two main pollutant that have most major effect on human health, long or short exposure to this pollutant can have both mild and severe impact on health such as impaired respiratory system, cardiovascular diseases or even death (EEA 2013), also exposure to particulate matter decreases life expectancy by an average of one year, indoor pollution as a result of the biological agents in the indoor air which is due to damp and mould also increase the risk of developing respiratory disease in children, there are two man type of pollutant which are the primary pollutant (WHO fact sheet 2011). Pollu tant can be classified into two namely primary pollutant and secondary pollutant; primary pollutants are the pollutants release directly into the atmosphere from the source while secondary pollutants are those type of pollutant forms when primary pollutants react with other chemical in the atmosphere, also type of pollutant and concentration can be indoor or outdoor pollutant, indoor pollutant include carbon monoxide, nitrogen oxide, volatile organic compounds and smoke, while outdoor pollutant are ozone, sulphur dioxide and particle. (COMEAP 2013) WHO define health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity (WHO 1948) Environment generally affects human health directly or indirectly... ...ssion standards of generator plants, industries emission and car emissions. - Deforestation bush burning and also incinerator burning should be barn all around the country in other to improve the air quality. - Laws should be put in place to barn public smoking as its been done in United Kingdom. - Long chimneys should be compulsory for all industries making use of fossil fuels and also emitting smoke into the atmosphere to avoid pollutants and acid rain which also affect the health of the populace. CONCLUSION Good air quality is vital for human health, Air pollution expose human to ill-health and by reducing the level of pollutant emission in the atmosphere general risk of disease can be reduce worldwide; considerable reduction in the exposure to air pollution can be achieved through the decrease in the concentration of the pollutants in the atmosphere.

The Da Vinci Code Chapter 56-59

CHAPTER 56 Sophie stared at Teabing a long moment and then turned to Langdon. â€Å"The Holy Grail is a person?† Langdon nodded. â€Å"A woman, in fact.† From the blank look on Sophie's face, Langdon could tell they had already lost her. He recalled having a similar reaction the first time he heard the statement. It was not until he understood the symbology behind the Grail that the feminine connection became clear. Teabing apparently had a similar thought. â€Å"Robert, perhaps this is the moment for the symbologist to clarify?† He went to a nearby end table, found a piece of paper, and laid it in front of Langdon. Langdon pulled a pen from his pocket. â€Å"Sophie, are you familiar with the modern icons for male and female?† He drew the common male symbol The Da Vinci Code The Da Vinci Code â€Å"Of course,† she said. â€Å"These,† he said quietly,† are not the original symbols for male and female. Many people incorrectly assume the male symbol is derived from a shield and spear, while the female symbol represents a mirror reflecting beauty. In fact, the symbols originated as ancient astronomical symbols for the planet-god Mars and planet-goddess Venus. The original symbols are far simpler.† Langdon drew another icon on the paper. The Da Vinci Code â€Å"This symbol is the original icon for male,†he told her. â€Å"A rudimentary phallus.† â€Å"Quite to the point,† Sophie said. â€Å"As it were,† Teabing added. Langdon went on. â€Å"This icon is formally known as the blade, and it represents aggression and manhood. In fact, this exact phallus symbol is still used today on modern military uniforms to denote rank.† â€Å"Indeed.† Teabing grinned. â€Å"The more penises you have, the higher your rank. Boys will be boys.† Langdon winced. â€Å"Moving on, the female symbol, as you might imagine, is the exact opposite.† He drew another symbol on the page. â€Å"This is called the chalice.† The Da Vinci Code Sophie glanced up, looking surprised. Langdon could see she had made the connection. â€Å"The chalice,† he said,† resembles a cup or vessel, and more important, it resembles the shape of a woman's womb. This symbol communicates femininity, womanhood, and fertility.† Langdon looked directly at her now.† Sophie, legend tells us the Holy Grail is a chalice – a cup. But the Grail's description as a chaliceis actually an allegory to protect the true nature of the Holy Grail. That is to say, the legend uses the chalice as a metaphor for something far more important.† â€Å"A woman,† Sophie said. â€Å"Exactly.† Langdon smiled. â€Å"The Grail is literally the ancient symbol for womanhood, and the Holy Grail represents the sacred feminine and the goddess, which of course has now been lost, virtually eliminated by the Church. The power of the female and her ability to produce life was once very sacred, but it posed a threat to the rise of the predominantly male Church, and so the sacred feminine was demonized and called unclean. It was man, not God, who created the concept of â€Å"original sin,† whereby Eve tasted of the apple and caused the downfall of the human race. Woman, once the sacred giver of life, was now the enemy.† â€Å"I should add,† Teabing chimed,† that this concept of woman as life-bringer was the foundation of ancient religion. Childbirth was mystical and powerful. Sadly, Christian philosophy decided to embezzle the female's creative power by ignoring biological truth and making man the Creator. Genesis tells us that Eve was created from Adam's rib. Woman became an offshoot of man. And a sinful one at that. Genesis was the beginning of the end for the goddess.† â€Å"The Grail,† Langdon said,† is symbolic of the lost goddess. When Christianity came along, the old pagan religions did not die easily. Legends of chivalric quests for the lost Grail were in fact stories of forbidden quests to find the lost sacred feminine. Knights who claimed to be† searching for the chalice† were speaking in code as a way to protect themselves from a Church that had subjugated women, banished the Goddess, burned nonbelievers, and forbidden the pagan reverence for the sacred feminine.† Sophie shook her head. â€Å"I'm sorry, when you said the Holy Grail was a person, I thought you meant it was an actual person.† â€Å"It is,† Langdon said. â€Å"And not just any person,† Teabing blurted, clambering excitedly to his feet. â€Å"A woman who carried with her a secret so powerful that, if revealed, it threatened to devastate the very foundation of Christianity!† Sophie looked overwhelmed. â€Å"Is this woman well known in history?† â€Å"Quite.† Teabing collected his crutches and motioned down the hall. â€Å"And if we adjourn to the study, my friends, it would be my honor to show you Da Vinci's painting of her.† Two rooms away, in the kitchen, manservant Remy Legaludec stood in silence before a television. The news station was broadcasting photos of a man and woman†¦ the same two individuals to whom Remy had just served tea. CHAPTER 57 Standing at the roadblock outside the Depository Bank of Zurich, Lieutenant Collet wondered what was taking Fache so long to come up with the search warrant. The bankers were obviously hiding something. They claimed Langdon and Neveu had arrived earlier and were turned away from the bank because they did not have proper account identification. So why won't they let us inside for a look? Finally, Collet's cellular phone rang. It was the command post at the Louvre. â€Å"Do we have a search warrant yet?† Collet demanded. â€Å"Forget about the bank, Lieutenant,† the agent told him. â€Å"We just got a tip. We have the exact location where Langdon and Neveu are hiding.† Collet sat down hard on the hood of his car. â€Å"You're kidding.† â€Å"I have an address in the suburbs. Somewhere near Versailles.† â€Å"Does Captain Fache know?† â€Å"Not yet. He's busy on an important call.† â€Å"I'm on my way. Have him call as soon as he's free.† Collet took down the address and jumped in his car. As he peeled away from the bank, Collet realized he had forgotten to ask who had tipped DCPJ off to Langdon's location. Not that it mattered. Collet had been blessed with a chance to redeem his skepticism and earlier blunders. He was about to make the most high-profile arrest of his career. Collet radioed the five cars accompanying him. â€Å"No sirens, men. Langdon can't know we're coming.† Forty kilometers away, a black Audi pulled off a rural road and parked in the shadows on the edge of a field. Silas got out and peered through the rungs of the wrought-iron fence that encircled the vast compound before him. He gazed up the long moonlit slope to the chateau in the distance. The downstairs lights were all ablaze. Odd for this hour, Silas thought, smiling. The information the Teacher had given him was obviously accurate. I will not leave this house without the keystone, he vowed. I will not fail the bishop and the Teacher. Checking the thirteen-round clip in his Heckler Koch, Silas pushed it through the bars and let it fall onto the mossy ground inside the compound. Then, gripping the top of the fence, he heaved himself up and over, dropping to the ground on the other side. Ignoring the slash of pain from his cilice, Silas retrieved his gun and began the long trek up the grassy slope. CHAPTER 58 Teabing's† study† was like no study Sophie had ever seen. Six or seven times larger than even the most luxurious of office spaces, the knight's cabinet de travail resembled an ungainly hybrid of science laboratory, archival library, and indoor flea market. Lit by three overhead chandeliers, the boundless tile floor was dotted with clustered islands of worktables buried beneath books, artwork, artifacts, and a surprising amount of electronic gear – computers, projectors, microscopes, copy machines, and flatbed scanners. â€Å"I converted the ballroom,† Teabing said, looking sheepish as he shuffled into the room. â€Å"I have little occasion to dance.† Sophie felt as if the entire night had become some kind of twilight zone where nothing was as she expected. â€Å"This is all for your work?† â€Å"Learning the truth has become my life's love,† Teabing said. â€Å"And the Sangreal is my favorite mistress.† The Holy Grail is a woman, Sophie thought, her mind a collage of interrelated ideas that seemed to make no sense. â€Å"You said you have a picture of this woman who you claim is the Holy Grail.† â€Å"Yes, but it is not I who claim she is the Grail. Christ Himself made that claim.† â€Å"Which one is the painting?† Sophie asked, scanning the walls.† Hmmm†¦Ã¢â‚¬  Teabing made a show of seeming to have forgotten. â€Å"The Holy Grail. The Sangreal. The Chalice.† He wheeled suddenly and pointed to the far wall. On it hung an eight-foot-long print of The Last Supper, the same exact image Sophie had just been looking at. â€Å"There she is!† Sophie was certain she had missed something. â€Å"That's the same painting you just showed me.† He winked. â€Å"I know, but the enlargement is so much more exciting. Don't you think?† Sophie turned to Langdon for help. â€Å"I'm lost.† Langdon smiled. â€Å"As it turns out, the Holy Grail does indeed make an appearance in The LastSupper.Leonardo included her prominently.† â€Å"Hold on,† Sophie said. â€Å"You told me the Holy Grail is a woman.The Last Supper is a painting of thirteen men.† â€Å"Is it?† Teabing arched his eyebrows. â€Å"Take a closer look.† Uncertain, Sophie made her way closer to the painting, scanning the thirteen figures – Jesus Christ in the middle, six disciples on His left, and six on His right. â€Å"They're all men,† she confirmed. â€Å"Oh?† Teabing said. â€Å"How about the one seated in the place of honor, at the right hand of the Lord?† Sophie examined the figure to Jesus' immediate right, focusing in. As she studied the person's face and body, a wave of astonishment rose within her. The individual had flowing red hair, delicate folded hands, and the hint of a bosom. It was, without a doubt†¦ female. â€Å"That's a woman!† Sophie exclaimed. Teabing was laughing. â€Å"Surprise, surprise. Believe me, it's no mistake. Leonardo was skilled at painting the difference between the sexes.† Sophie could not take her eyes from the woman beside Christ. The Last Supper is supposed to be thirteen men.Who is this woman? Although Sophie had seen this classic image many times, she had not once noticed this glaring discrepancy. â€Å"Everyone misses it,† Teabing said. â€Å"Our preconceived notions of this scene are so powerful that our mind blocks out the incongruity and overrides our eyes.† â€Å"It's known as skitoma,†Langdon added. â€Å"The brain does it sometimes with powerful symbols.† â€Å"Another reason you might have missed the woman,† Teabing said,† is that many of the photographs in art books were taken before 1954, when the details were still hidden beneath layers of grime and several restorative repaintings done by clumsy hands in the eighteenth century. Now, at last, the fresco has been cleaned down to Da Vinci's original layer of paint.† He motioned to the photograph. â€Å"Et voila!† Sophie moved closer to the image. The woman to Jesus' right was young and pious-looking, with a demure face, beautiful red hair, and hands folded quietly. This is the woman who singlehandedly could crumble the Church? â€Å"Who is she?† Sophie asked. â€Å"That, my dear,† Teabing replied,† is Mary Magdalene.† Sophie turned. â€Å"The prostitute?† Teabing drew a short breath, as if the word had injured him personally. â€Å"Magdalene was no such thing. That unfortunate misconception is the legacy of a smear campaign launched by the early Church. The Church needed to defame Mary Magdalene in order to cover up her dangerous secret – her role as the Holy Grail.† â€Å"Her role?† â€Å"As I mentioned,† Teabing clarified,† the early Church needed to convince the world that the mortal prophet Jesus was a divine being. Therefore, any gospels that described earthly aspects of Jesus' life had to be omitted from the Bible. Unfortunately for the early editors, one particularly troubling earthly theme kept recurring in the gospels. Mary Magdalene.† He paused. â€Å"More specifically, her marriage to Jesus Christ.† â€Å"I beg your pardon?† Sophie's eyes moved to Langdon and then back to Teabing. â€Å"It's a matter of historical record,† Teabing said,† and Da Vinci was certainly aware of that fact. The Last Supper practically shouts at the viewer that Jesus and Magdalene were a pair.† Sophie glanced back to the fresco. â€Å"Notice that Jesus and Magdalene are clothed as mirror images of one another.† Teabing pointed to the two individuals in the center of the fresco. Sophie was mesmerized. Sure enough, their clothes were inverse colors. Jesus wore a red robe and blue cloak; Mary Magdalene wore a blue robe and red cloak. Yin and yang. â€Å"Venturing into the more bizarre,† Teabing said,† note that Jesus and His bride appear to be joined at the hip and are leaning away from one another as if to create this clearly delineated negative space between them.† Even before Teabing traced the contour for her, Sophie saw it – the indisputable V shape at the focal point of the painting. It was the same symbol Langdon had drawn earlier for the Grail, the chalice, and the female womb. â€Å"Finally,† Teabing said,† if you view Jesus and Magdalene as compositional elements rather than as people, you will see another obvious shape leap out at you.† He paused. â€Å"A letter of the alphabet.† Sophie saw it at once. To say the letter leapt out at her was an understatement. The letter was suddenly all Sophie could see. Glaring in the center of the painting was the unquestionable outline of an enormous, flawlessly formed letter M. â€Å"A bit too perfect for coincidence, wouldn't you say?† Teabing asked. Sophie was amazed. â€Å"Why is it there?† Teabing shrugged. â€Å"Conspiracy theorists will tell you it stands for Matrimonio or Mary Magdalene. To be honest, nobody is certain. The only certainty is that the hidden M is no mistake. Countless Grail-related works contain the hidden letter M – whether as watermarks, underpaintings, or compositional allusions. The most blatant M, of course, is emblazoned on the altar at Our Lady of Paris in London, which was designed by a former Grand Master of the Priory of Sion, Jean Cocteau.† Sophie weighed the information. â€Å"I'll admit, the hidden M's are intriguing, although I assume nobody is claiming they are proof of Jesus' marriage to Magdalene.† â€Å"No, no,† Teabing said, going to a nearby table of books. â€Å"As I said earlier, the marriage of Jesus and Mary Magdalene is part of the historical record.† He began pawing through his book collection. â€Å"Moreover, Jesus as a married man makes infinitely more sense than our standard biblical view of Jesus as a bachelor.† â€Å"Why?† Sophie asked. â€Å"Because Jesus was a Jew,† Langdon said, taking over while Teabing searched for his book,† and the social decorum during that time virtually forbid a Jewish man to be unmarried. According to Jewish custom, celibacy was condemned, and the obligation for a Jewish father was to find a suitable wife for his son. If Jesus were not married, at least one of the Bible's gospels would have mentioned it and offered some explanation for His unnatural state of bachelorhood.† Teabing located a huge book and pulled it toward him across the table. The leather-bound edition was poster-sized, like a huge atlas. The cover read: The Gnostic Gospels.Teabing heaved it open, and Langdon and Sophie joined him. Sophie could see it contained photographs of what appeared to be magnified passages of ancient documents – tattered papyrus with handwritten text. She did not recognize the ancient language, but the facing pages bore typed translations. â€Å"These are photocopies of the Nag Hammadi and Dead Sea scrolls, which I mentioned earlier,† Teabing said. â€Å"The earliest Christian records. Troublingly, they do not match up with the gospels in the Bible.† Flipping toward the middle of the book, Teabing pointed to a passage. â€Å"The Gospel of Philip is always a good place to start.† Sophie read the passage: And the companion of the Saviour is Mary Magdalene. Christ loved her more than all the disciples and used to kiss her often on her mouth. The rest of the disciples were offended by it and expressed disapproval. They said to him,† Why do you love her more than all of us?† The words surprised Sophie, and yet they hardly seemed conclusive. â€Å"It says nothing of marriage.† â€Å"Au contraire.† Teabing smiled, pointing to the first line. â€Å"As any Aramaic scholar will tell you, the word companion, in those days, literally meant spouse.† Langdon concurred with a nod. Sophie read the first line again. And the companion of the Saviour is Mary Magdalene. Teabing flipped through the book and pointed out several other passages that, to Sophie's surprise, clearly suggested Magdalene and Jesus had a romantic relationship. As she read the passages, Sophie recalled an angry priest who had banged on her grandfather's door when she was a schoolgirl. â€Å"Is this the home of Jacques Sauniere?† the priest had demanded, glaring down at young Sophie when she pulled open the door. â€Å"I want to talk to him about this editorial he wrote.† The priest held up a newspaper. Sophie summoned her grandfather, and the two men disappeared into his study and closed the door. My grandfather wrote something in the paper? Sophie immediately ran to the kitchen and flipped through that morning's paper. She found her grandfather's name on an article on the second page. She read it. Sophie didn't understand all of what was said, but it sounded like the French government, under pressure from priests, had agreed to ban an American movie called The Last Temptation of Christ, which was about Jesus having sex with a lady called Mary Magdalene. Her grandfather's article said the Church was arrogant and wrong to ban it. No wonder the priest is mad, Sophie thought. â€Å"It's pornography! Sacrilege!† the priest yelled, emerging from the study and storming to the front door. â€Å"How can you possibly endorse that! This American Martin Scorsese is a blasphemer, and the Church will permit him no pulpit in France!† The priest slammed the door on his way out. When her grandfather came into the kitchen, he saw Sophie with the paper and frowned. â€Å"You're quick.† Sophie said,† You think Jesus Christ had a girlfriend?† â€Å"No, dear, I said the Church should not be allowed to tell us what notions we can and can't entertain.† â€Å"Did Jesus have a girlfriend?† Her grandfather was silent for several moments. â€Å"Would it be so bad if He did?† Sophie considered it and then shrugged. â€Å"I wouldn't mind.† Sir Leigh Teabing was still talking. â€Å"I shan't bore you with the countless references to Jesus and Magdalene's union. That has been explored ad nauseum by modern historians. I would, however, like to point out the following.† He motioned to another passage. â€Å"This is from the Gospel of Mary Magdalene.† Sophie had not known a gospel existed in Magdalene's words. She read the text: And Peter said,† Did the Saviour really speak with a woman without our knowledge? Are we to turn about and all listen to her? Did he prefer her to us?† And Levi answered,† Peter, you have always been hot-tempered. Now I see you contending against the woman like an adversary. If the Saviour made her worthy, who are you indeed to reject her? Surely the Saviour knows her very well. That is why he loved her more than us.† â€Å"The woman they are speaking of,† Teabing explained,† is Mary Magdalene. Peter is jealous of her.† â€Å"Because Jesus preferred Mary?† â€Å"Not only that. The stakes were far greater than mere affection. At this point in the gospels, Jesus suspects He will soon be captured and crucified. So He gives Mary Magdalene instructions on how to carry on His Church after He is gone. As a result, Peter expresses his discontent over playing second fiddle to a woman. I daresay Peter was something of a sexist.† Sophie was trying to keep up. â€Å"This is Saint Peter. The rock on which Jesus built His Church.† â€Å"The same, except for one catch. According to these unaltered gospels, it was not Peter to whom Christ gave directions with which to establish the Christian Church. It was Mary Magdalene.† Sophie looked at him. â€Å"You're saying the Christian Church was to be carried on by a woman?† â€Å"That was the plan. Jesus was the original feminist. He intended for the future of His Church to be in the hands of Mary Magdalene.† â€Å"And Peter had a problem with that,† Langdon said, pointing to The Last Supper. â€Å"That's Peter there. You can see that Da Vinci was well aware of how Peter felt about Mary Magdalene.† Again, Sophie was speechless. In the painting, Peter was leaning menacingly toward Mary Magdalene and slicing his blade-like hand across her neck. The same threatening gesture as in Madonna of the Rocks! â€Å"And here too,† Langdon said, pointing now to the crowd of disciples near Peter. â€Å"A bit ominous, no?† Sophie squinted and saw a hand emerging from the crowd of disciples. â€Å"Is that hand wielding a dagger?† â€Å"Yes. Stranger still, if you count the arms, you'll see that this hand belongs to†¦ no one at all. It's disembodied. Anonymous.† Sophie was starting to feel overwhelmed. â€Å"I'm sorry, I still don't understand how all of this makes Mary Magdalene the Holy Grail.† â€Å"Aha!† Teabing exclaimed again. â€Å"Therein lies the rub!† He turned once more to the table and pulled out a large chart, spreading it out for her. It was an elaborate genealogy. â€Å"Few people realize that Mary Magdalene, in addition to being Christ's right hand, was a powerful woman already.† Sophie could now see the title of the family tree. THE TRIBE OF BENJAMIN â€Å"Mary Magdalene is here,† Teabing said, pointing near the top of the genealogy. Sophie was surprised. â€Å"She was of the House of Benjamin?† â€Å"Indeed,† Teabing said. â€Å"Mary Magdalene was of royal descent.† â€Å"But I was under the impression Magdalene was poor.† Teabing shook his head. â€Å"Magdalene was recast as a whore in order to erase evidence of her powerful family ties.† Sophie found herself again glancing at Langdon, who again nodded. She turned back to Teabing. â€Å"But why would the early Church care if Magdalene had royal blood?† The Briton smiled. â€Å"My dear child, it was not Mary Magdalene's royal blood that concerned the Church so much as it was her consorting with Christ, who also had royal blood. As you know, the Book of Matthew tells us that Jesus was of the House of David. A descendant of King Solomon – King of the Jews. By marrying into the powerful House of Benjamin, Jesus fused two royal bloodlines, creating a potent political union with the potential of making a legitimate claim to the throne and restoring the line of kings as it was under Solomon.† Sophie sensed he was at last coming to his point. Teabing looked excited now. â€Å"The legend of the Holy Grail is a legend about royal blood. When Grail legend speaks of ‘the chalice that held the blood of Christ'†¦ it speaks, in fact, of Mary Magdalene – the female womb that carried Jesus' royal bloodline.† The words seemed to echo across the ballroom and back before they fully registered in Sophie's mind. Mary Magdalene carried the royal bloodline of Jesus Christ?† But how could Christ have a bloodline unless†¦ ?† She paused and looked at Langdon. Langdon smiled softly. â€Å"Unless they had a child.† Sophie stood transfixed.† Behold,† Teabing proclaimed,† the greatest cover-up in human history. Not only was Jesus Christ married, but He was a father. My dear, Mary Magdalene was the Holy Vessel. She was the chalice that bore the royal bloodline of Jesus Christ. She was the womb that bore the lineage, and the vine from which the sacred fruit sprang forth!† Sophie felt the hairs stand up on her arms. â€Å"But how could a secret that big be kept quiet all of these years?† â€Å"Heavens!† Teabing said. â€Å"It has been anything but quiet! The royal bloodline of Jesus Christ is the source of the most enduring legend of all time – the Holy Grail. Magdalene's story has been shouted from the rooftops for centuries in all kinds of metaphors and languages. Her story is everywhere once you open your eyes.† â€Å"And the Sangreal documents?† Sophie said. â€Å"They allegedly contain proof that Jesus had a royal bloodline?† â€Å"They do.† â€Å"So the entire Holy Grail legend is all about royal blood?† â€Å"Quite literally,† Teabing said. â€Å"The word Sangreal derives from San Greal – or Holy Grail. But in its most ancient form, the word Sangreal was divided in a different spot.† Teabing wrote on a piece of scrap paper and handed it to her. She read what he had written. Sang Real Instantly, Sophie recognized the translation. Sang Real literally meant Royal Blood. CHAPTER 59 The male receptionist in the lobby of the Opus Dei headquarters on Lexington Avenue in New York City was surprised to hear Bishop Aringarosa's voice on the line. â€Å"Good evening, sir.† â€Å"Have I had any messages?† the bishop demanded, sounding unusually anxious.† Yes, sir. I'm very glad you called in. I couldn't reach you in your apartment. You had an urgent phone message about half an hour ago.† â€Å"Yes?† He sounded relieved by the news. â€Å"Did the caller leave a name?† â€Å"No, sir, just a number.† The operator relayed the number. â€Å"Prefix thirty-three? That's France, am I right?† â€Å"Yes, sir. Paris. The caller said it was critical you contact him immediately.† â€Å"Thank you. I have been waiting for that call.† Aringarosa quickly severed the connection. As the receptionist hung up the receiver, he wondered why Aringarosa's phone connection sounded so crackly. The bishop's daily schedule showed him in New York this weekend, and yet he sounded a world away. The receptionist shrugged it off. Bishop Aringarosa had been acting very strangely the last few months. My cellular phone must not have been receiving, Aringarosa thought as the Fiat approached the exit for Rome's Ciampino Charter Airport. The Teacher was trying to reach me.Despite Aringarosa's concern at having missed the call, he felt encouraged that the Teacher felt confident enough to call Opus Dei headquarters directly. Things must have gone well in Paris tonight. As Aringarosa began dialing the number, he felt excited to know he would soon be in Paris. I'll beon the ground before dawn.Aringarosa had a chartered turbo prop awaiting him here for the short flight to France. Commercial carriers were not an option at this hour, especially considering the contents of his briefcase. The line began to ring. A female voice answered. â€Å"Direction Centrale Police Judidaire.† Aringarosa felt himself hesitate. This was unexpected. â€Å"Ah, yes†¦ I was asked to call this number?† â€Å"Qui etes-vous?† the woman said. â€Å"Your name?† Aringarosa was uncertain if he should reveal it. The French Judicial Police? â€Å"Your name, monsieur?† the woman pressed. â€Å"Bishop Manuel Aringarosa.† â€Å"Un moment.† There was a click on the line. After a long wait, another man came on, his tone gruff and concerned. â€Å"Bishop, I am glad I finally reached you. You and I have much to discuss.†

Abortion: the most controversial issues in America

Nina Emmrich English 1 Abortion Guy Thorvaldsen 14, April 14, 2013 Abortion, this is one of the most controversial issues in America. It’s been an issue for over 200 years. In 1973 it was protected under law. But today it isn’t. Most American’s believe that it’s a sin to have an abortion while others see it as a choice to do it. There have been many legal cases against and also for abortion. Many have won but many have lost. This issue will never end. It will always be an argument. By having an abortion the mother is killing and innocent child who has no say in it.The family and father should also have a say in it as well. A little before the 1800’s states practiced some form of the English Common Law which happened to also lack codification. Abortion and unwed pregnancy didn’t exist in this time period. Finding the history of abortion is more difficult than people can imagine because there aren’t very many records of it to go off of. Starting in the 1600’s, there was the first conviction of the intent to abort a child. This went down in the state of Maryland, and then four years later another girl was arrested for murder because she had an abortion.This also happened in Maryland, but that case was dropped after the woman married the only witness who of course refused to testify. Another case that happened was in 1710 where Virginia Law made it a capital crime to be pregnant and then be found with a dead baby. In 1719 Delaware made it that anyone who counseled abortion or even infanticide an accessory to murder. According to Olasky’s notes â€Å"infanticide was probably the most frequent way of killing unwanted, illegitimate children†. â€Å"Abortifacients were known to and used in the early America.But by using them â€Å"was like playing Russian roulette with three bullets in the chamber†. So already there are beginning to make it a crime to have abortions. (abort73. com) There are many key factors that went into the process of deciding a case. They didn’t always have specific legislation for abortion and infanticide, those who did happened to have the same problem. It was impossible to have the right evidence to convict someone, and even more so pregnancy was hard to confirm. There was never a corpse or a witness to prove it. But on the bright side there was a great deal of the ury that had sympathy for the abandoned and desperate woman. Either way there was a lot of non-legislative factors that had been working against infanticide and abortion. A major factor was that the man should â€Å"act honorably† and propose to the women if he got her pregnant before they were married. (abort73. com) To give more to the influence of the society was the religious and scientific community. They condemned abortion both for how the bible speaks of an unborn child and also for the well-known testimony of church pillars like John Calvin who forbade abortion.Fr om the 1600’s-1800’s the scientific community believed that babies actually existed before they were conceived. This was also another anti-abortion influence. The difficulty confirming pregnancy before quickening made early abortions almost impossible, and late term abortions ruined marriage prospects, and were extremely dangerous. (Abort73. com pg. 2) There’s more to the history than just the community. Lawmakers had to start dealing with abortion in the late 1800’s. It was 1821 when the first abortion legislation had passes in Connecticut.The lawmakers everywhere else tried to keep up. New York legislation changed on abortion 10 times between 1828 and 1881. (Abort73. com) Abortion should be illegal. When women have abortions they are killing innocent children. It’s a sin to do so. Of course it’s a choice of the mother but what about the family. What about the father? Don’t they have a say in what happens to their child. As America g rew and expanded, most of the support mechanisms that helped provide for women during their crisis pregnancies had begun to want.The increase in social isolation and separation through urbanization had removed the societal and familial safety net for pregnant and non-married women had to fall back on. The concealment of a women’s pregnancy alone with smothering the baby after it was born was then considered a choice. Therefore abortion was beginning to get a foothold, but it was still not considered legitimate or legal. The frequency of was increasing as more young women found alone and pregnant. Dr. John Trader of Missouri stated that â€Å"contended that men were (the ones) pushing women into abortion†.So it goes to show that the men are also part of the abortion’s happening. (abort73. com) Slowly the opposition of abortion began to lose a lot of its moral framework. In the med. Books abortion was beginning to be counseled against for the potential risks as it had been presented to many women instead of the life being destroyed. It was said that â€Å"the right to destroy† became the central belief to a women named Margaret Sanger. She began to expose it in publicity. She would celebrate the virtue of sexual promiscuity and she would attack any women’s shelter.She then would have gone on to fount Planned Parenthood which still today remains the largest abortion provider in the United States. The government funding was required to remove all religious indoctrination and professional social workers replaced the evangelically-oriented matrons. The compassion shifted from helping to do what is right to doing whatever people feel like doing. (abort73. com) The birth control issue split the pro-life community for many years and hamstrung their efforts during the crucial 1960’s. (abort73. om) In the year of 1962 there were reports of a women who died form and illegal abortion and she was then cut into pieces which had horri fied the entire nation. Sherri Finkbine became famous women for having an abortion in Sweden because she was worried that her child was going to be disabled. An average American had begun to see illegal abortion instead of abortion itself as the real problem. In the year of 1967 Colorado and California became the first states to legalize abortions for only pregnancies that resulted in rape, incest, or pregnancies that threatened the life of a women as well as a pregnancy of a severely handicapped child.Then within the next three years, Alaska, Arkansas, Delaware, Georgia, Hawaii, Kansas, Maryland, Mississippi, New Mexico, North Carolina, Oregon, South Carolina and Virginia soon followed. Then in 1970 New York became one of the first states to offer unrestricted abortion, but only during the first 24 weeks of the women’s pregnancy. Then in 1971 the Roe v. Wade case came to trial. The verdict was decided in 1973 which was that all state laws regulating abortion were strict. And the demand became the law of the land. So as you can see that abortion had a lot of history in front of it, but does it still make it right for it to be legal?Some believe that abortion should only be legal for certain reasons, such as Rape victims. While many disagree with this option there are many who do agree. A woman who was raped and is carrying the rapist baby should have the right to decide what she would like to do with the baby. It's not the court's decision it's hers. It's been a woman's right since the Roe V. Wade case that abortion is legal. This caused an outrage. There were protests out on the steps of the courthouse where people were screaming that they are allowing woman to kill innocent children.And they have a point too. Killing a child when they have no say in it is considered murder to some people. Anytime you kill a human being is murder so how is this any different. A woman in the army was 19 and was in an abusive relationship and he had gotten her pregnant. She didn’t want to tell him. She was called a whore, a tramp and embarrassment to her family. They told her to come home and discuss it as a family. Well little did she know they had made an appointment for her to get an abortion. No matter what she said it was all wrong.Her oldest brother whom she respected wouldn’t even talk to her he was so ashamed of her. Her family kept telling her to get an abortion but she was against it. The argument lasted 3 hours and finally she went to bed. But her family wouldn't leave her alone until she made a decision. She was denied food that night and when she awoke the next morning she was denied food as well. So she finally gave in and they drove her to the clinic. She had the abortion and she saw a 16 year old girl in there and she hugged her and they cried together.Her parents as well as her brothers never apologized for their actions. Her take away from this experience is that she can be compassionate to young teens that have made the horrible choice of having an abortion. She is now 47, married with 2 children and adopting a third. This story shows that there is regret to getting an abortion. She never stopped thinking of her first child. She told her now 21 year old daughter who had gotten pregnant 19 about what happened and her granddaughter is now one year old. There will always be that regret of having a child. (abort73. om) There was a case called Roe v. Wade. This was a case between a single pregnant that brought a class action challenge to the constitutionality of the Texas criminal abortion laws by procuring or attempting an abortion on medical terms for the mother. A licensed physician named Hallford who had to cases pending against him was somehow permitted to intervene. A married couple who were unable to bare a child separately attacked the laws as well based on alleged injury from the failure of contraceptives, pregnancy as well as impairment of the wife's health.Roe and Hallford were standing to sue and presented justiciable controversies. The court decided to that the abortion status void as vague as those plaintiff's Ninth and Fourteenth Amendments. The District Court granted declaratory relief to Roe and Hallford. It was then decided in 1973 that the Court's ruled that the Texas criminal abortion statures are unconstitutional. (Cornell. edu) There are places that do abortions. These are called abortion clinics. The main one that is most popular is Planned Parenthood. These places should not exist.Allowing young teens to come in and murder their child is wrong. In the case Planned Parenthood v. Casey the Supreme Court considered a Pennsylvania law that imposed the regulations on abortion. This case was not directly connected to Roe v. Wade. Although the Court didn't contend that Roe v. Wade was a correct application of reasoned judgment. In extreme arrogance the Court declared â€Å"where the performance of its judicial duties, the Court decides the case in such way a s to resolve the sort of intensely divisive controversy reflected in Roe and those rare comparable cases†¦.Contending sides of a national controversy to end their national division by accepting a common mandate rooted in the constitution. † In this case Planned Parenthood because of the case Roe v. Wade and how abortion is legal because it's a national law. (Lifenews. com) There are so many reasons as to why abortion should not be legal but we have to look at the other side of the picture. We have to look at reasons why is should be legal and the reasons behind that. The big reason is Rape victims. Why should they have to carry the rapist's baby. They should have every right to get rid of it.And with abortion being legal they can. To them it's not a sin. They are getting rid of something that was part of a horror that they went through. They have the right to decide and to them they aren’t doing the wrong thing they are doing the right thing. No one can stop them. They have the freedom to choose. Abortion is used for many different reasons. Those reasons can be that the mother was raped and didn’t want to keep the child or if they didn’t abort the mother would die. These are two serious reasons as to why some people are for abortion.It can save someone's life when it comes to the decision of life or death. Or it could be the free release from something tragic that happened to someone. Abortion isn't all bad in some ways. Those two reasons are important to some people. A mother who doesn't want to carry a rapist's baby shouldn't have to. And if the child is killing the mother and abortion is the only way to save her life then do it. There are medical reasons to do abortions. Not just personal. Not only is it the mother's decision but it should also be the father's decision as well.He should have a right to decide whether the baby lives or not. He helped create it. It's unfair to think that he will never be able to see is child be cause the mother aborted it without him knowing. It's unfair. Every father should have the right of say in what happens to his child. Then there's the issue of the family. The family should also have a say in what happens as well. They can help take care of the baby. Be there for the mother. Help her along the way. Help her, guide her. Give her and the baby love. They will be there for. The mother should want that, should have that.The families are supposed to be there for their children. Love them no matter what happens to them. They will love their grandchildren just the same. So they should have a right of say as well. They will help guide the mother through the tough times. They will be there for her and the child, no matter what. So with all that history and all that information, have you come to a conclusion as to whether you are for or against it. You should be against it. It's murder. Killing an innocent child is just wrong. Everyone has the right to do as they please but in common sense it's the worst thing you could do.There are other options like keeping the baby or giving it up for adoption. Why kill the baby when you can give it life. Give it a home, a place to eat, sleep, live and be happy. Or give it to a family whose always wanted a child but could never have one of their own. Give that baby a future. Don’t kill it. It deserves to live. Everyone deserves to live. Not die. It's wrong. So with all this information, I hope you've made the right decision as to whose side you're on. Killing an innocent child is wrong, and it needs to be stopped.
