Learning Expirience Essay Example for Free

Learning Expirience Essay Experience can shape our behavior and personality. More over our experiences contribute to our development over time. Learning process occurs when we experience situation that have negative or positive effect on us. In this essay I will briefly describe my personal learning experience; I will also define the concept of learning, and will provide analysis of what I have learned from this experience. In addition my essay will include the analysis and application of classical and operant conditioning as well as cognitive- social learning. My Experience Every person’s identity is formed by the various roles that they perform in the world. In fact becoming a mother is one more such role and it has psychological implications. Four month ago I became a mother to a wonderful, my first baby boy. The experience of giving birth, as well as being home with a newborn for the first few weeks was overwhelming, painful, and emotionally tiring. I am 25 years old and was so exciting to becoming a mother, however when my son was born for the first few weeks I have experienced anxiety, stress, depression, fear and even anger. It has been almost 4 month and my baby is my life, I cannot imagine how I was getting frustrated and feeling all those things when my baby is my joy. Today I am still tired, and stressed, however anger and depression is gone. I have learned from this experience that I need to accept the change in my life, and avoid becoming frustrated. Being prepared for things to be different could have prepared me to deal with situation differently. Also positive attitude should have been my best ally instead of being afraid and having negative thoughts. At last I have learned from this experience that I need to try to develop a new and balanced lifestyle that takes into consideration all areas of my new life. Learning Learning is the process whereby knowledge is created through the transformation of experience (David A. Kolb, 1984). As we learn, we alter the way we perceive our environment, the way we interpret the incoming stimuli, and therefore the way we interact, or behave (Carpenter Huffman, 2012). Learning through Classical Conditioning One of the best-known characteristics of behavioral learning theory is classical conditioning. Classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus (Carpenter Huffman, 2012). There are basic principles of classical conditioning process. Such as the unconditioned stimulus (UC) and unconditioned response (UR), as well as conditioned stimulus (CS) and conditioned response (CR) (Carpenter Huffman, 2012). The unconditioned stimulus is one that unconditionally, naturally, and automatically triggers a response (â€Å"The propositional nature of human associative learning,† 2009). For example, baby crying made me feel sad and frustrated, and baby smiling made me feel loved, happy and positive. For instance, when I saw my bay for the first time the feeling of pain was simply gone. As I spend those first weeks with my baby although I have had mood swings and feeling of anger sometimes, however every time I looked at my baby I naturally felt better and calmer. The unconditioned response is the unlearned response that occurs naturally in response to the unconditioned stimulus. For example, feel of love in response to my baby smile is unconditioned stimulus. The conditioned stimulus is previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response (â€Å"The propositional nature of human associative learning,† 2009). For example, when my baby cried I felt frustration and in the same time my husband was trying to explain me something thus my husband voice would be conditioned stimulus. Although the sound of my husband voice is unrelated to my baby’s cry and feeling of frustration, if the sound of his voice was paired multiple times with the baby’s cry, the sound would eventually trigger the conditioned response. The conditioned response is the learned response to the previously neutral stimulus. For instance, feeling frustrated when I heard my husband talking to me. In my view classical conditioning is a useful technique that can be applied by creating a positive environment to help people to overcome anxiety, fear and frustration. For example, a situation like my baby’s crying with pleasant surroundings would have helped me to learn new associations. Instead of feeling anxious, frustrated and angry in that situation, I learn to stay relax and calm (Carpenter Huffman, 2012). Operant Conditioning Operant conditioning is a technique of learning that happens through rewards and punishments for behavior. Through operant conditioning, an association is made between a behavior and a consequence for that behavior (â€Å"The propositional nature of human associative learning,† 2009). The elimination of an undesirable outcome can be used to decrease or prevent undesirable behavior. Feeling frustrated, being angry with situation simply led to more stress and created more problems for myself emotionally and physically. Positive reinforcement: Getting to know my baby, his first smile and lough created a positive and happy environment thus increasing my positive behavior. To conclude learning process revolves around human life. People learn something new every single day, thus creating new experiences and knowledge. Self-development and growth naturally occurs through learning.

One of the world's best known advocates of non-violent social change strategies, Martin Luther King, Jr., synthesized ideas drawn from many different cultural traditions. Born in Atlanta on January 15, 1929, King's roots were in the African-American Baptist church. He was the grandson of the Rev. A. D. Williams, pastor of Ebenezer Baptist church and a founder of Atlanta's NAACP chapter, and the son of Martin Luther King, Sr., who succeeded Williams as Ebenezer's pastor and also became a civil rights leader. Although, from an early age, King resented religious emotionalism and questioned literal interpretations of scripture, he nevertheless greatly admired black social gospel proponents such as his father who saw the church as a instrument for improving the lives of African Americans. Morehouse College president Benjamin Mays and other proponents of Christian social activism influenced King's decision after his junior year at Morehouse to become a minister and thereby serve society. His continued skepticism, however, shaped his subsequent theological studies at Crozer Theological Seminary in Chester, Pennsylvania, and at Boston University, where he received a doctorate in systematic theology in 1955. Rejecting offers for academic positions, King decided while completing his Ph. D. requirements to return to the South and accepted the pastorate of Dexter Avenue Baptist Church in Montgomery, Alabama. On December 5, 1955, five days after Montgomery civil rights activist Rosa Parks refused to obey the city's rules mandating segregation on buses, black residents launched a bus boycott and elected King as president of the newly-formed Montgomery Improvement Association. As the boycott continued during 1956, King gained national prominence as a result of his exceptional oratorical skills and personal courage. His house was bombed and he was convicted along with other boycott leaders on charges of conspiring to interfere with the bus company's operations. Despite these attempts to suppress the movement, Montgomery bus were desegregated in December, 1956, after the United States Supreme Court declared Alabama's segregation laws unconstitutional. In 1957, seeking to build upon the success of the Montgomery boycott movement, King and other southern black ministers founded the Southern Christian Leadership Conference (SCLC). As SCLC's president, King emphasized the goal of black voting rights when he spoke at the Lincoln Memorial during the 1957 Prayer Pilgrimage for Freedom. During 1958, he published his first book, Stride Toward Freedom: The Montgomery Story. The following year, he toured India, increased his understanding of Gandhian non-violent strategies.

Angels Demons Chapter 20-23

20 Phase two, the Hassassin thought, striding into the darkened tunnel. The torch in his hand was overkill. He knew that. But it was for effect. Effect was everything. Fear, he had learned, was his ally. Fear cripples faster than any implement of war. There was no mirror in the passage to admire his disguise, but he could sense from the shadow of his billowing robe that he was perfect. Blending in was part of the plan†¦ part of the depravity of the plot. In his wildest dreams he had never imagined playing this part. Two weeks ago, he would have considered the task awaiting him at the far end of this tunnel impossible. A suicide mission. Walking naked into a lion's lair. But Janus had changed the definition of impossible. The secrets Janus had shared with the Hassassin in the last two weeks had been numerous†¦ this very tunnel being one of them. Ancient, and yet still perfectly passable. As he drew closer to his enemy, the Hassassin wondered if what awaited him inside would be as easy as Janus had promised. Janus had assured him someone on the inside would make the necessary arrangements. Someone on the inside. Incredible. The more he considered it, the more he realized it was child's play. Wahad†¦ tintain†¦ thalatha†¦ arbaa, he said to himself in Arabic as he neared the end. One†¦ two†¦ three†¦ four†¦ 21 â€Å"I sense you've heard of antimatter, Mr. Langdon?† Vittoria was studying him, her dark skin in stark contrast to the white lab. Langdon looked up. He felt suddenly dumb. â€Å"Yes. Well†¦ sort of.† A faint smile crossed her lips. â€Å"You watch Star Trek.† Langdon flushed. â€Å"Well, my students enjoy†¦Ã¢â‚¬  He frowned. â€Å"Isn't antimatter what fuels the U.S.S. Enterprise?† She nodded. â€Å"Good science fiction has its roots in good science.† â€Å"So antimatter is real?† â€Å"A fact of nature. Everything has an opposite. Protons have electrons. Up-quarks have down-quarks. There is a cosmic symmetry at the subatomic level. Antimatter is yin to matter's yang. It balances the physical equation.† Langdon thought of Galileo's belief of duality. â€Å"Scientists have known since 1918,† Vittoria said, â€Å"that two kinds of matter were created in the Big Bang. One matter is the kind we see here on earth, making up rocks, trees, people. The other is its inverse – identical to matter in all respects except that the charges of its particles are reversed.† Kohler spoke as though emerging from a fog. His voice sounded suddenly precarious. â€Å"But there are enormous technological barriers to actually storing antimatter. What about neutralization?† â€Å"My father built a reverse polarity vacuum to pull the antimatter positrons out of the accelerator before they could decay.† Kohler scowled. â€Å"But a vacuum would pull out the matter also. There would be no way to separate the particles.† â€Å"He applied a magnetic field. Matter arced right, and antimatter arced left. They are polar opposites.† At that instant, Kohler's wall of doubt seemed to crack. He looked up at Vittoria in clear astonishment and then without warning was overcome by a fit of coughing. â€Å"Incred†¦ ible†¦Ã¢â‚¬  he said, wiping his mouth, â€Å"and yet†¦Ã¢â‚¬  It seemed his logic was still resisting. â€Å"Yet even if the vacuum worked, these canisters are made of matter. Antimatter cannot be stored inside canisters made out of matter. The antimatter would instantly react with – â€Å" â€Å"The specimen is not touching the canister,† Vittoria said, apparently expecting the question. â€Å"The antimatter is suspended. The canisters are called ‘antimatter traps' because they literally trap the antimatter in the center of the canister, suspending it at a safe distance from the sides and bottom.† â€Å"Suspended? But†¦ how?† â€Å"Between two intersecting magnetic fields. Here, have a look.† Vittoria walked across the room and retrieved a large electronic apparatus. The contraption reminded Langdon of some sort of cartoon ray gun – a wide cannonlike barrel with a sighting scope on top and a tangle of electronics dangling below. Vittoria aligned the scope with one of the canisters, peered into the eyepiece, and calibrated some knobs. Then she stepped away, offering Kohler a look. Kohler looked nonplussed. â€Å"You collected visible amounts?† â€Å"Five thousand nanograms,† Vittoria said. â€Å"A liquid plasma containing millions of positrons.† â€Å"Millions? But a few particles is all anyone has ever detected†¦ anywhere.† â€Å"Xenon,† Vittoria said flatly. â€Å"He accelerated the particle beam through a jet of xenon, stripping away the electrons. He insisted on keeping the exact procedure a secret, but it involved simultaneously injecting raw electrons into the accelerator.† Langdon felt lost, wondering if their conversation was still in English. Kohler paused, the lines in his brow deepening. Suddenly he drew a short breath. He slumped like he'd been hit with a bullet. â€Å"Technically that would leave†¦Ã¢â‚¬  Vittoria nodded. â€Å"Yes. Lots of it.† Kohler returned his gaze to the canister before him. With a look of uncertainty, he hoisted himself in his chair and placed his eye to the viewer, peering inside. He stared a long time without saying anything. When he finally sat down, his forehead was covered with sweat. The lines on his face had disappeared. His voice was a whisper. â€Å"My God†¦ you really did it.† Vittoria nodded. â€Å"My father did it.† â€Å"I†¦ I don't know what to say.† Vittoria turned to Langdon. â€Å"Would you like a look?† She motioned to the viewing device. Uncertain what to expect, Langdon moved forward. From two feet away, the canister appeared empty. Whatever was inside was infinitesimal. Langdon placed his eye to the viewer. It took a moment for the image before him to come into focus. Then he saw it. The object was not on the bottom of the container as he expected, but rather it was floating in the center – suspended in midair – a shimmering globule of mercurylike liquid. Hovering as if by magic, the liquid tumbled in space. Metallic wavelets rippled across the droplet's surface. The suspended fluid reminded Langdon of a video he had once seen of a water droplet in zero G. Although he knew the globule was microscopic, he could see every changing gorge and undulation as the ball of plasma rolled slowly in suspension. â€Å"It's†¦ floating,† he said. â€Å"It had better be,† Vittoria replied. â€Å"Antimatter is highly unstable. Energetically speaking, antimatter is the mirror image of matter, so the two instantly cancel each other out if they come in contact. Keeping antimatter isolated from matter is a challenge, of course, because everything on earth is made of matter. The samples have to be stored without ever touching anything at all – even air.† Langdon was amazed. Talk about working in a vacuum. â€Å"These antimatter traps?† Kohler interrupted, looking amazed as he ran a pallid finger around one's base. â€Å"They are your father's design?† â€Å"Actually,† she said, â€Å"they are mine.† Kohler looked up. Vittoria's voice was unassuming. â€Å"My father produced the first particles of antimatter but was stymied by how to store them. I suggested these. Airtight nanocomposite shells with opposing electromagnets at each end.† â€Å"It seems your father's genius has rubbed off.† â€Å"Not really. I borrowed the idea from nature. Portuguese man-o'-wars trap fish between their tentacles using nematocystic charges. Same principle here. Each canister has two electromagnets, one at each end. Their opposing magnetic fields intersect in the center of the canister and hold the antimatter there, suspended in midvacuum.† Langdon looked again at the canister. Antimatter floating in a vacuum, not touching anything at all. Kohler was right. It was genius. â€Å"Where's the power source for the magnets?† Kohler asked. Vittoria pointed. â€Å"In the pillar beneath the trap. The canisters are screwed into a docking port that continuously recharges them so the magnets never fail.† â€Å"And if the field fails?† â€Å"The obvious. The antimatter falls out of suspension, hits the bottom of the trap, and we see an annihilation.† Langdon's ears pricked up. â€Å"Annihilation?† He didn't like the sound of it. Vittoria looked unconcerned. â€Å"Yes. If antimatter and matter make contact, both are destroyed instantly. Physicists call the process ‘annihilation.' â€Å" Langdon nodded. â€Å"Oh.† â€Å"It is nature's simplest reaction. A particle of matter and a particle of antimatter combine to release two new particles – called photons. A photon is effectively a tiny puff of light.† Langdon had read about photons – light particles – the purest form of energy. He decided to refrain from asking about Captain Kirk's use of photon torpedoes against the Klingons. â€Å"So if the antimatter falls, we see a tiny puff of light?† Vittoria shrugged. â€Å"Depends what you call tiny. Here, let me demonstrate.† She reached for the canister and started to unscrew it from its charging podium. Without warning, Kohler let out a cry of terror and lunged forward, knocking her hands away. â€Å"Vittoria! Are you insane?† 22 Kohler, incredibly, was standing for a moment, teetering on two withered legs. His face was white with fear. â€Å"Vittoria! You can't remove that trap!† Langdon watched, bewildered by the director's sudden panic. â€Å"Five hundred nanograms!† Kohler said. â€Å"If you break the magnetic field – â€Å" â€Å"Director,† Vittoria assured, â€Å"it's perfectly safe. Every trap has a failsafe – a back-up battery in case it is removed from its recharger. The specimen remains suspended even if I remove the canister.† Kohler looked uncertain. Then, hesitantly, he settled back into his chair. â€Å"The batteries activate automatically,† Vittoria said, â€Å"when the trap is moved from the recharger. They work for twenty-four hours. Like a reserve tank of gas.† She turned to Langdon, as if sensing his discomfort. â€Å"Antimatter has some astonishing characteristics, Mr. Langdon, which make it quite dangerous. A ten milligram sample – the volume of a grain of sand – is hypothesized to hold as much energy as about two hundred metric tons of conventional rocket fuel.† Langdon's head was spinning again. â€Å"It is the energy source of tomorrow. A thousand times more powerful than nuclear energy. One hundred percent efficient. No byproducts. No radiation. No pollution. A few grams could power a major city for a week.† Grams? Langdon stepped uneasily back from the podium. â€Å"Don't worry,† Vittoria said. â€Å"These samples are minuscule fractions of a gram – millionths. Relatively harmless.† She reached for the canister again and twisted it from its docking platform. Kohler twitched but did not interfere. As the trap came free, there was a sharp beep, and a small LED display activated near the base of the trap. The red digits blinked, counting down from twenty-four hours. 24:00:00†¦ 23:59:59†¦ 23:59:58†¦ Langdon studied the descending counter and decided it looked unsettlingly like a time bomb. â€Å"The battery,† Vittoria explained, â€Å"will run for the full twenty-four hours before dying. It can be recharged by placing the trap back on the podium. It's designed as a safety measure, but it's also convenient for transport.† â€Å"Transport?† Kohler looked thunderstruck. â€Å"You take this stuff out of the lab?† â€Å"Of course not,† Vittoria said. â€Å"But the mobility allows us to study it.† Vittoria led Langdon and Kohler to the far end of the room. She pulled a curtain aside to reveal a window, beyond which was a large room. The walls, floors, and ceiling were entirely plated in steel. The room reminded Langdon of the holding tank of an oil freighter he had once taken to Papua New Guinea to study Hanta body graffiti. â€Å"It's an annihilation tank,† Vittoria declared. Kohler looked up. â€Å"You actually observe annihilations?† â€Å"My father was fascinated with the physics of the Big Bang – large amounts of energy from minuscule kernels of matter.† Vittoria pulled open a steel drawer beneath the window. She placed the trap inside the drawer and closed it. Then she pulled a lever beside the drawer. A moment later, the trap appeared on the other side of the glass, rolling smoothly in a wide arc across the metal floor until it came to a stop near the center of the room. Vittoria gave a tight smile. â€Å"You're about to witness your first antimatter-matter annihilation. A few millionths of a gram. A relatively minuscule specimen.† Langdon looked out at the antimatter trap sitting alone on the floor of the enormous tank. Kohler also turned toward the window, looking uncertain. â€Å"Normally,† Vittoria explained, â€Å"we'd have to wait the full twenty-four hours until the batteries died, but this chamber contains magnets beneath the floor that can override the trap, pulling the antimatter out of suspension. And when the matter and antimatter touch†¦Ã¢â‚¬  â€Å"Annihilation,† Kohler whispered. â€Å"One more thing,† Vittoria said. â€Å"Antimatter releases pure energy. A one hundred percent conversion of mass to photons. So don't look directly at the sample. Shield your eyes.† Langdon was wary, but he now sensed Vittoria was being overly dramatic. Don't look directly at the canister? The device was more than thirty yards away, behind an ultrathick wall of tinted Plexiglas. Moreover, the speck in the canister was invisible, microscopic. Shield my eyes? Langdon thought. How much energy could that speck possibly – Vittoria pressed the button. Instantly, Langdon was blinded. A brilliant point of light shone in the canister and then exploded outward in a shock wave of light that radiated in all directions, erupting against the window before him with thunderous force. He stumbled back as the detonation rocked the vault. The light burned bright for a moment, searing, and then, after an instant, it rushed back inward, absorbing in on itself, and collapsing into a tiny speck that disappeared to nothing. Langdon blinked in pain, slowly recovering his eyesight. He squinted into the smoldering chamber. The canister on the floor had entirely disappeared. Vaporized. Not a trace. He stared in wonder. â€Å"G†¦ God.† Vittoria nodded sadly. â€Å"That's precisely what my father said.† 23 Kohler was staring into the annihilation chamber with a look of utter amazement at the spectacle he had just seen. Robert Langdon was beside him, looking even more dazed. â€Å"I want to see my father,† Vittoria demanded. â€Å"I showed you the lab. Now I want to see my father.† Kohler turned slowly, apparently not hearing her. â€Å"Why did you wait so long, Vittoria? You and your father should have told me about this discovery immediately.† Vittoria stared at him. How many reasons do you want? â€Å"Director, we can argue about this later. Right now, I want to see my father.† â€Å"Do you know what this technology implies?† â€Å"Sure,† Vittoria shot back. â€Å"Revenue for CERN. A lot of it. Now I want – â€Å" â€Å"Is that why you kept it secret?† Kohler demanded, clearly baiting her. â€Å"Because you feared the board and I would vote to license it out?† â€Å"It should be licensed,† Vittoria fired back, feeling herself dragged into the argument. â€Å"Antimatter is important technology. But it's also dangerous. My father and I wanted time to refine the procedures and make it safe.† â€Å"In other words, you didn't trust the board of directors to place prudent science before financial greed.† Vittoria was surprised with the indifference in Kohler's tone. â€Å"There were other issues as well,† she said. â€Å"My father wanted time to present antimatter in the appropriate light.† â€Å"Meaning?† What do you think I mean? â€Å"Matter from energy? Something from nothing? It's practically proof that Genesis is a scientific possibility.† â€Å"So he didn't want the religious implications of his discovery lost in an onslaught of commercialism?† â€Å"In a manner of speaking.† â€Å"And you?† Vittoria's concerns, ironically, were somewhat the opposite. Commercialism was critical for the success of any new energy source. Although antimatter technology had staggering potential as an efficient and nonpolluting energy source – if unveiled prematurely, antimatter ran the risk of being vilified by the politics and PR fiascoes that had killed nuclear and solar power. Nuclear had proliferated before it was safe, and there were accidents. Solar had proliferated before it was efficient, and people lost money. Both technologies got bad reputations and withered on the vine. â€Å"My interests,† Vittoria said, â€Å"were a bit less lofty than uniting science and religion.† â€Å"The environment,† Kohler ventured assuredly. â€Å"Limitless energy. No strip mining. No pollution. No radiation. Antimatter technology could save the planet.† â€Å"Or destroy it,† Kohler quipped. â€Å"Depending on who uses it for what.† Vittoria felt a chill emanating from Kohler's crippled form. â€Å"Who else knew about this?† he asked. â€Å"No one,† Vittoria said. â€Å"I told you that.† â€Å"Then why do you think your father was killed?† Vittoria's muscles tightened. â€Å"I have no idea. He had enemies here at CERN, you know that, but it couldn't have had anything to do with antimatter. We swore to each other to keep it between us for another few months, until we were ready.† â€Å"And you're certain your father kept his vow of silence?† Now Vittoria was getting mad. â€Å"My father has kept tougher vows than that!† â€Å"And you told no one?† â€Å"Of course not!† Kohler exhaled. He paused, as though choosing his next words carefully. â€Å"Suppose someone did find out. And suppose someone gained access to this lab. What do you imagine they would be after? Did your father have notes down here? Documentation of his processes?† â€Å"Director, I've been patient. I need some answers now. You keep talking about a break-in, but you saw the retina scan. My father has been vigilant about secrecy and security.† â€Å"Humor me,† Kohler snapped, startling her. â€Å"What would be missing?† â€Å"I have no idea.† Vittoria angrily scanned the lab. All the antimatter specimens were accounted for. Her father's work area looked in order. â€Å"Nobody came in here,† she declared. â€Å"Everything up here looks fine.† Kohler looked surprised. â€Å"Up here?† Vittoria had said it instinctively. â€Å"Yes, here in the upper lab.† â€Å"You're using the lower lab too?† â€Å"For storage.† Kohler rolled toward her, coughing again. â€Å"You're using the Haz-Mat chamber for storage? Storage of what?† Hazardous material, what else! Vittoria was losing her patience. â€Å"Antimatter.† Kohler lifted himself on the arms of his chair. â€Å"There are other specimens? Why the hell didn't you tell me!† â€Å"I just did,† Vittoria fired back. â€Å"And you've barely given me a chance!† â€Å"We need to check those specimens,† Kohler said. â€Å"Now.† â€Å"Specimen,† Vittoria corrected. â€Å"Singular. And it's fine. Nobody could ever – â€Å" â€Å"Only one?† Kohler hesitated. â€Å"Why isn't it up here?† â€Å"My father wanted it below the bedrock as a precaution. It's larger than the others.† The look of alarm that shot between Kohler and Langdon was not lost on Vittoria. Kohler rolled toward her again. â€Å"You created a specimen larger than five hundred nanograms?† â€Å"A necessity,† Vittoria defended. â€Å"We had to prove the input/yield threshold could be safely crossed.† The question with new fuel sources, she knew, was always one of input vs. yield – how much money one had to expend to harvest the fuel. Building an oil rig to yield a single barrel of oil was a losing endeavor. However, if that same rig, with minimal added expense, could deliver millions of barrels, then you were in business. Antimatter was the same way. Firing up sixteen miles of electromagnets to create a tiny specimen of antimatter expended more energy than the resulting antimatter contained. In order to prove antimatter efficient and viable, one had to create specimens of a larger magnitude. Although Vittoria's father had been hesitant to create a large specimen, Vittoria had pushed him hard. She argued that in order for antimatter to be taken seriously, she and her father had to prove two things. First, that cost-effective amounts could be produced. And second, that the specimens could be safely stored. In the end she had won, and her father had acquiesced against his better judgment. Not, however, without some firm guidelines regarding secrecy and access. The antimatter, her father had insisted, would be stored in Haz-Mat – a small granite hollow, an additional seventy-five feet below ground. The specimen would be their secret. And only the two of them would have access. â€Å"Vittoria?† Kohler insisted, his voice tense. â€Å"How large a specimen did you and your father create?† Vittoria felt a wry pleasure inside. She knew the amount would stun even the great Maximilian Kohler. She pictured the antimatter below. An incredible sight. Suspended inside the trap, perfectly visible to the naked eye, danced a tiny sphere of antimatter. This was no microscopic speck. This was a droplet the size of a BB. Vittoria took a deep breath. â€Å"A full quarter of a gram.† The blood drained from Kohler's face. â€Å"What!† He broke into a fit of coughing. â€Å"A quarter of a gram? That converts to†¦ almost five kilotons!† Kilotons. Vittoria hated the word. It was one she and her father never used. A kiloton was equal to 1,000 metric tons of TNT. Kilotons were for weaponry. Payload. Destructive power. She and her father spoke in electron volts and joules – constructive energy output. â€Å"That much antimatter could literally liquidate everything in a half-mile radius!† Kohler exclaimed. â€Å"Yes, if annihilated all at once,† Vittoria shot back, â€Å"which nobody would ever do!† â€Å"Except someone who didn't know better. Or if your power source failed!† Kohler was already heading for the elevator. â€Å"Which is why my father kept it in Haz-Mat under a fail-safe power and a redundant security system.† Kohler turned, looking hopeful. â€Å"You have additional security on Haz-Mat?† â€Å"Yes. A second retina-scan.† Kohler spoke only two words. â€Å"Downstairs. Now.† The freight elevator dropped like a rock. Another seventy-five feet into the earth. Vittoria was certain she sensed fear in both men as the elevator fell deeper. Kohler's usually emotionless face was taut. I know, Vittoria thought, the sample is enormous, but the precautions we've taken are – They reached the bottom. The elevator opened, and Vittoria led the way down the dimly lit corridor. Up ahead the corridor dead-ended at a huge steel door. HAZ-MAT. The retina scan device beside the door was identical to the one upstairs. She approached. Carefully, she aligned her eye with the lens. She pulled back. Something was wrong. The usually spotless lens was spattered†¦ smeared with something that looked like†¦ blood? Confused she turned to the two men, but her gaze met waxen faces. Both Kohler and Langdon were white, their eyes fixed on the floor at her feet. Vittoria followed their line of sight†¦ down. â€Å"No!† Langdon yelled, reaching for her. But it was too late. Vittoria's vision locked on the object on the floor. It was both utterly foreign and intimately familiar to her. It took only an instant. Then, with a reeling horror, she knew. Staring up at her from the floor, discarded like a piece of trash, was an eyeball. She would have recognized that shade of hazel anywhere.
