Speed Meter Quotes

Clocks measure arbitrary meters of time, but not its speed. Nobody knows if time is speeding up, or slowing down. Nobody knows what it is. How much time is there in a day? Not how many hours, minutes, seconds: how much TIME do we have? This day?

Hockey players can also brace pretty hard against the ice. A player skating at full speed can stop in the space of a few meters, which means the force they’re exerting on the ice is pretty substantial. (It also suggests that if you started to slowly rotate a hockey rink, it could tilt up to 50 degrees before the players would all slide to one end. Clearly, experiments are needed to confirm this.)

The story of the rapper and the story of the hustler are like rap itself, two kinds of rhythm working together, having a conversation with each other, doing more together than they could do apart. It's been said that the thing that makes rap special, that makes it different both from pop music and from written poetry, is that it's built around two kinds of rhythm. The first kind of rhythm is the meter. In poetry, the meter is abstract, but in rap, the meter is something you literally hear: it's the beat. The beat in a song never stops, it never varies. No matter what other sounds are on the track, even if it's a Timbaland production with all kinds of offbeat fills and electronics, a rap song is usually built bar by bar, four-beat measure by four-beat measure. It's like time itself, ticking off relentlessly in a rhythm that never varies and never stops. When you think about it like that, you realize the beat is everywhere, you just have to tap into it. You can bang it out on a project wall or an 808 drum machine or just use your hands. You can beatbox it with your mouth. But the beat is only one half of a rap song's rhythm. The other is the flow. When a rapper jumps on a beat, he adds his own rhythm. Sometimes you stay in the pocket of the beat and just let the rhymes land on the square so that the beat and flow become one. But sometimes the flow cops up the beat, breaks the beat into smaller units, forces in multiple syllables and repeated sounds and internal rhymes, or hangs a drunken leg over the last bap and keeps going, sneaks out of that bitch. The flow isn't like time, it's like life. It's like a heartbeat or the way you breathe, it can jump, speed up, slow down, stop, or pound right through like a machine. If the beat is time, flow is what we do with that time, how we live through it. The beat is everywhere, but every life has to find its own flow. Just like beats and flows work together, rapping and hustling, for me at least, live through each other. Those early raps were beautiful in their way and a whole generation of us felt represented for the first time when we heard them. But there's a reason the culture evolved beyond that playful, partying lyrical style. Even when we recognized the voices, and recognized the style, and even personally knew the cats who were on the records, the content didn't always reflect the lives we were leading. There was a distance between what was becoming rap's signature style - the relentlessness, the swagger, the complex wordplay - and the substance of the songs. The culture had to go somewhere else to grow. It had to come home.

Here in our solar system, a hundred-meter-wide asteroid sails into Earth every millennium or so at speeds upward of fifty thousand miles an hour, generating a destructive impact equal to 2,500 atomic bombs.

Guinea worms grow up to a meter long inside the bodies of their victims, then escape by burrowing out of their skin. The only treatment, even now, is to speed the process of exit by winding the worms onto a stick as they emerge.

Even though we now have a decent picture of the planet's climatological past, never in the earth's entire recorded history has there been warming at anything like this speed- by one estimate, around ten times faster than at any point in the last 66 million years. Every year, the average American emits enough carbon to melt 10,000 tons of ice in the Antarctic ice sheets- enough to add 10,000 cubic meters of water to the ocean. Every minute, each of us adds five gallons.

When an object impacts the Moon at high speed, it sets the Moon slightly wobbling. Eventually the vibrations die down but not in so short a period as eight hundred years. Such a quivering can be studied by laser reflection techniques. The Apollo astronauts emplaced in several locales on the Moon special mirrors called laser retroreflectors. When a laser beam from Earth strikes the mirror and bounces back, the round-trip travel time can be measured with remarkable precision. This time multiplied by the speed of light gives us the distance to the Moon at that moment to equally remarkable precision. Such measurements, performed over a period of years, reveal the Moon to be librating, or quivering with a period (about three years) and amplitude (about three meters), consistent with the idea that the crater Giordano Bruno was gouged out less than a thousand years ago.

Our current government doesn’t give a f*** about transportation. They only give a f*** about making money. When it comes to synchronizing the traffic lights and cutting down on that lost time sitting in traffic, they don’t have the IQ for that. But when it comes to stuff that makes them money—chickens*** tickets, parking meters, and speed traps—they’re all Lex Luthor. They turn into diabolical mad geniuses.

Imagine that light is shining out from a flashlight. According to common sense, if we run fast enough we could in principle catch up with the front of the beam of light as it advances forward. Common sense might even suggest that we could jog alongside the front of the beam if we managed to run at the speed of light. But if we are to follow Maxwell’s equations to the letter, then no matter how fast we run, the beam still recedes away from us at a speed of 299,792,458 meters per second.

The rover crested a nearby dune with the trailer in tow. It slowed for a few moments, then continued toward the ship at top speed. It came to a stop twenty meters away. There it remained for ten minutes while the astronaut inside suited up. He stumbled excitedly out of the airlock, falling to the ground then scrambling to his feet. Beholding the MAV, he gestured to it with both arms, as if in disbelief. He leaped into the air several times, arms held high with fists clenched. Then he knelt on one knee and fist-pumped repeatedly. Running to the spacecraft, he hugged Landing Strut B. After a few moments, he broke off the embrace to perform another round of leaping celebrations. Now fatigued, the astronaut stood with arms akimbo, looking up at the sleek lines of the engineering marvel before him.

Well, no offense,” he began, and Hal had a moment to reflect that whenever people began with “no offense” they invariably went on to be extremely offensive. “But what qualifies Thorn to train us? I mean . . . he’s Thorn, after all. No offense,” he repeated. Thorn smiled at him but the smile never reached his eyes. Hal turned to him. “Thorn, would you like to show Jesper how qualified you are?” Thorn appeared to think about the question. Then he moved with blinding speed, covering the ground between himself and Jesper. Jesper, a former thief, was accustomed to moving quickly when threatened. But he never had time to register that Thorn was moving. The old sea wolf’s left hand closed on Jesper’s collar in an iron grip and he hoisted the boy off his feet, holding him suspended, his feet dangling clear of the ground. Then he gathered himself and hurled Jesper away like a sack of potatoes. The boy flew several meters through the air, hit the ground and lost his footing, crashing over on his back. As he lay winded, he looked up into Thorn’s bearded face, a face wreathed in a fierce smile. “How’s that for qualifications?” Jesper nodded several times, and waved weakly in reply. “Tha’s pretty good,” he gasped breathlessly. “Pretty good indeed.

God said, 'Let there be light.' Here's a paraphrase: Let there be electromagnetic radiation with varying wavelengths traveling at 186,282 miles per second. Let there be radiowaves, microwaves, and X-rays. Let there be photosynthesis and fiber optics. Let there be LASIK surgery, satellite communication, and suntans. Oh, and let there be rainbows after rainstorms. 'Let there be light.' These are God's first recorded words. This is God's first recorded miracle. Light is the source of vision; without it we can't see a thing. Light is the key to technology; it's how we can talk to someone halfway around the world without so much as a second's delay because light can circle the globe seven and a half times a second. Light is the first link in the food chain; no photosynthesis equals no food. Light is the basis of health; the absence of light causes everything from vitamin D deficiency to depression. Light is the origin of energy; in Einstein's equation E = MC squared, energy (E) is defined as mass (M) times the speed of light (C) squared. The speed of light is the constant. And light is the measuring stick for space-time; a meter is defined as the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second. Light is the alpha and omega of everything, and that includes you.

Cheng Xin stared at the death lines, her terror mixed with awe. “If these are trails, why don’t they spread?” Guan Yifan clutched Cheng Xin’s arm. “I was just getting to that. We’ve got to get out of here. Leave not just Planet Gray, but the entire system. This is a very dangerous place. Death lines are not like regular trails. Without disturbance, they’ll stay like this, with a diameter equal to the effective surface of the curvature engine. But if they’re disturbed, they’ll spread very rapidly. A death line of this size can expand to cover a region the size of a solar system. Scientists call this phenomenon a death line rupture.” “Does a rupture make the speed of light zero in the entire region?” “No, no. After rupture, it turns into a regular trail. The speed of light inside goes up as the trail dissipates over a wider region, but it will never be much more than a dozen meters per second. After these death lines expand, this entire system might turn into a reduced-lightspeed black hole, or a black domain.… Let’s go.” Cheng Xin and Guan Yifan turned toward the shuttle and began to run and leap. “What kind of disturbance makes them spread?” Cheng Xin asked. She turned to give the death lines another glance. Behind them, the five death lines cast long shadows that stretched across the plain to the horizon. “We’re not sure. Some theories suggest that the appearance of other curvature trails nearby would cause disturbance. We’ve confirmed that curvature trails within a short distance can influence each other.” “So, if Halo accelerates—” “That’s why we must get farther away using only the fusion engine before engaging the curvature engine. We’ve got to move … using your units of measurement … at least forty astronomical units away.” After

Colonel Fedmahn Kassad shouted a FORCE battle cry and charged through the dust storm to intercept the Shrike before it covered the final thirty meters to where Sol Weintraub crouched next to Brawne Lamia. The Shrike paused, its head swiveling frictionlessly, red eyes gleaming. Kassad armed his assault rifle and moved down the slope with reckless speed. The Shrike shifted. Kassad saw its movement through time as a slow blur, noting even as he watched the Shrike that movement in the valley had ceased, sand hung motionless in the air, and the light from the glowing Tombs had taken on a thick, amberish quality. Kassad’s skinsuit was somehow shifting with the Shrike, following it through its movements through time. The creature’s head snapped up, attentive now, and its four arms extended like blades from a knife, fingers snapping open in sharp greeting. Kassad skidded to a halt ten meters from the thing and activated the assault rifle, slagging the sand beneath the Shrike in a full-power wide-beam burst. The Shrike glowed as its carapace and steel-sculpture legs reflected the hellish light beneath and around it. Then the three meters of monster began to sink as the sand bubbled into a lake of molten glass beneath it. Kassad shouted in triumph as he stepped closer, playing the widebeam on the Shrike and ground the way he had sprayed his friends with stolen irrigation hoses in the Tharsis slums as a boy. The Shrike sank. Its arms splayed at the sand and rock, trying to find purchase. Sparks flew. It shifted, time running backward like a reversed holie, but Kassad shifted with it, realizing that Moneta was helping him, her suit slaved to his but guiding him through time, and then he was spraying the creature again with concentrated heat greater than the surface of a sun, melting sand beneath it, and watching the rocks around it burst into flame. Sinking in this cauldron of flame and molten rock, the Shrike threw back its head, opened its wide crevasse of a mouth, and bellowed. Kassad almost stopped firing in his shock at hearing noise from the thing. The Shrike’s scream resounded like a dragon’s roar mixed with the blast of a fusion rocket. The screech set Kassad’s teeth on edge, vibrated from the cliff walls, and tumbled suspended dust to the ground. Kassad switched to high-velocity solid shot and fired ten thousand microfléchettes at the creature’s face.

One evening in April a thirty-two-year-old woman, unconscious and severely injured, was admitted to the hospital in a provincial town south of Copenhagen. She had a concussion and internal bleeding, her legs and arms were broken in several places, and she had deep lesions in her face. A gas station attendant in a neighboring village, beside the bridge over the highway to Copenhagen, had seen her go the wrong way up the exit and drive at high speed into the oncoming traffic. The first three approaching cars managed to maneuver around her, but about 200 meters after the junction she collided head-on with a truck. The Dutch driver was admitted for observation but released the next day. According to his statement he started to brake a good 100 meters before the crash, while the car seemed to actually increase its speed over the last stretch. The front of the vehicle was totally crushed, part of the radiator was stuck between the road and the truck's bumper, and the woman had to be cut free. The spokesman for emergency services said it was a miracle she had survived. On arrival at the hospital the woman was in very critical condition, and it was twenty-four hours before she was out of serious danger. Her eyes were so badly damaged that she lost her sight. Her name was Lucca. Lucca Montale. Despite the name there was nothing particularly Italian about her appearance. She had auburn hair and green eyes in a narrow face with high cheek-bones. She was slim and fairly tall. It turned out she was Danish, born in Copenhagen. Her husband, Andreas Bark, arrived with their small son while she was still on the operating table. The couple's home was an isolated old farmhouse in the woods seven kilometers from the site of the accident. Andreas Bark told the police he had tried to stop his wife from driving. He thought she had just gone out for a breath of air when he heard the car start. By the time he got outside he saw it disappearing along the road. She had been drinking a lot. They had had a marital disagreement. Those were the words he used; he was not questioned further on that point. Early in the morning, when Lucca Montale was moved from the operating room into intensive care, her husband was still in the waiting room with the sleeping boy's head on his lap. He was looking out at the sky and the dark trees when Robert sat down next to him. Andreas Bark went on staring into the gray morning light with an exhausted, absent gaze. He seemed slightly younger than Robert, in his late thirties. He had dark, wavy hair and a prominent chin, his eyes were narrow and deep-set, and he was wearing a shabby leather jacket. Robert rested his hands on his knees in the green cotton trousers and looked down at the perforations in the leather uppers of his white clogs. He realized he had forgotten to take off his plastic cap after the operation. The thin plastic crackled between his hands. Andreas looked at him and Robert straightened up to meet his gaze. The boy woke.

DUTCH MASTERS: Historic Olympic Dominance AP SOCHI, Russia (AP) — Jorrit Bergsma set an Olympic record and led another Dutch speedskating sweep Tuesday, winning the 10,000 meters with an upset of countryman Sven Kramer. Kramer wanted this gold more than any other after giving away the longest race with an inexplicable mistake at the 2010 Vancouver Games. But Bergsma's finishing kick was a stunner, giving him a winning time of 12 minutes, 44.45 seconds. It was the fastest sea-level time ever and shattered the Olympic record of 12:58.55 set by South Korea's Lee Seung-hoon four years ago. Kramer settled for silver in 12:49.02. The bronze went to 37-year-old Bob de Jong. It was the fourth Dutch sweep of the podium at Adler Arena, giving them 19 speedskating medals in all. Bergsma's last five laps were all under 30 seconds, a pace Kramer simply couldn't match. Grimacing in a desperate search for more speed, his lap times climbed steadily higher. When the bell rang for the final lap, Bergsma already was celebrating in the infield. On his cool-down lap, Kramer stopped to shake hands with his countryman. Yet this was a bitter disappointment for the world's greatest distance skater, who already had captured his second straight 5,000 gold but really wanted to make up for the victory that got away in Vancouver. During a routine crossover on the backstretch four years ago, Kramer's coach, Gerard Kemkers, inexplicably directed him to the wrong lane. The skater dutifully followed the instructions, leading

So training smart, training effectively, involves cycling through the three zones in any given week or training block: 75 percent easy running, 5 to 10 percent running at target race paces, and 15 to 20 percent fast running or hill training in the third zone to spike the heart and breathing rates. In my 5-days-a-week running schedule, that cycle looks like this: On Monday, I cross-train. Tuesday, I do an easy run in zone one, then speed up to a target race pace for a mile or two of zone-two work. On Wednesday, it’s an easy zone-one run. Thursday is an intense third-zone workout with hills, speed intervals, or a combination of the two. Friday is a recovery day to give my body time to adapt. On Saturday, I do a relaxed run with perhaps another mile or two of zone-two race pace or zone-three speed. Sunday is a long, slow run. That constant cycling through the three zones—a hard day followed by an easy or rest day—gradually improves my performance in each zone and my overall fitness. But today is not about training. It’s about cranking up that treadmill yet again, pushing me to run ever faster in the third zone, so Vescovi can measure my max HR and my max VO2, the greatest amount of oxygen my heart and lungs can pump to muscles working at their peak. When I pass into this third zone, Vescovi and his team start cheering: “Great job!” “Awesome!” “Nice work.” They sound impressed. And when I am in the moment of running rather than watching myself later on film, I really think I am impressing them, that I am lighting up the computer screen with numbers they have rarely seen from a middle-aged marathoner, maybe even from an Olympian in her prime. It’s not impossible: A test of male endurance athletes in Sweden, all over the age of 80 and having 50 years of consistent training for cross-country skiing, found they had relative max VO2 values (“relative” because the person’s weight was included in the calculation) comparable to those of men half their age and 80 percent higher than their sedentary cohorts. And I am going for a high max VO2. I am hauling in air. I am running well over what should be my max HR of 170 (according to that oft-used mathematical formula, 220 − age) and way over the 162 calculated using the Gulati formula, which is considered to be more accurate for women (0.88 × age, the result of which is then subtracted from 206). Those mathematical formulas simply can’t account for individual variables and fitness levels. A more accurate way to measure max HR, other than the test I’m in the middle of, is to strap on a heart rate monitor and run four laps at a 400-meter track, starting out at a moderate pace and running faster on each lap, then running the last one full out. That should spike your heart into its maximum range. My high max HR is not surprising, since endurance runners usually develop both a higher maximum rate at peak effort and a lower rate at rest than unconditioned people. What is surprising is that as the treadmill

The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly but gets faster each minute after you hear this signal bodeboop. A sing lap should be completed every time you hear this sound. ding Remember to run in a straight line and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark. Get ready!... Start. ding

On the next clear night, look up in the direction of the constellation humanity calls Cancer. Between the pincers of the right claw of that giant crab in the sky sits a faint star. No matter how hard you stare, you won’t see it with the naked eye. It can only be viewed through a telescope with a thirty-meter aperture. Even if you could travel at the speed of light, fast enough to circle the earth seven and a half times in a single second, it would take over forty years to reach that star.

One pair of Chestnut-fronted Macaws preened each other for nearly an hour. Suddenly they stopped, made eye contact, and then the male, with his head bent low, climbed onto the female’s back. The female averted her tail, and he slid his tail under hers so that cloacal contact was made. If they were vocalizing, it was so quiet I could not hear it. He dismounted, they preened, and then he mounted her again. It was almost as if the romance of the rain, the intensity of the sensual experience of bathing, had precipitated sex. After the second go-round, they moved about a meter apart, preening themselves, and then, with chattering, squawking calls, lifted off, flying over the treetops at a great speed, perhaps searching for a suitable nest site. As if stimulated by the macaws, the Blue-headed Parrots also began to court, preening and billing each other around the head. Within minutes they, too, were copulating. Their contact was brief. I felt sure the rain had signaled the beginning of the intense courtship phase of these birds, triggering ancient physiological changes inside them—increases in the sex hormone that lead to enlarging testes and ripening ova. The rains pointed them toward mating, finding a nest, laying eggs. For my entire career I had wanted to watch wild parrots in this intense courtship phase. To find two species simultaneously mating was breathtaking.

He suddenly remembered an equation that he had created as a child, after his father had challenged him to determine at what point raindrops of 0.04-centimenter diameter, falling at a speed of 9 meters per second and at a frequency density of 15 drops per square meter per second, would saturate 25 square kilometers of space - taking into account raindrop overlap, naturally. Philip had created an equation in ten minutes, knowing, of course, that the bait and switch from meters to kilometers was merely a cheap trick. He wasn't a complete moron, not even at age nine.

Several strands of my long hair were cut. I watched the strands as they fluttered to the ground before being blown away by a breeze. Turning while still keeping low to the ground, I found a pair of legs directly in front of my face. I looked up to see another cloaked individual. “Hup!” Using the strength of my legs to push off the ground, I leapt up at a speed that was too fast for this person to keep up with. His foot missed as I moved backward. I came back in and swung my fist upward. A satisfying cracking noise echoed around the empty street as my fist slammed into the underside of this person’s chin. A garbled cry of pain emerged from the cloaked figure’s mouth as my attack sent the guy into the air. Blood and a tooth shot out of the cloaked person’s hood. My opponent flew backward in a parabolic arc, struck the ground hard, bounced several times, and rolled to a stop several meters away. “ALF!” a cry came from the first cloaked individual who attacked me. “You bastard!!” “It’s rich calling someone a bastard for fighting back after you attack him,” I muttered, though it seemed my attacker wasn’t paying any attention to what I said.

It’s a bit more complicated than that, but essentially, yes. The plane can carry bombs, but that’s not what it’d be using. A while back, there was a program called ‘Rods of God.’ It basically involved placing these twenty-meter-long rocket-assisted tungsten rods on a satellite in space. We could then have the satellite aim at a hardened underground bunker or a target that was heavily defended and release the rod from space. The rod would fall through the atmosphere, gaining in speed. Once in the upper atmosphere, a rocket on the back would power up and help the rod accelerate to speeds of up to Mach 20 or roughly fifteen thousand miles per hour. When it hit the target, it’d be like hitting it with a three-hundred-kiloton nuclear warhead, only without any of the nuclear fallout.

I say you are reading to slow. You need to read at least 93.5 mph. According to United Nations Educational, Scientific and Cultural Organization. Around 2.2 million new titles are published worldwide each year. If a book is in average 250 pages. Or 3 cm. That is 66 km of books every year. Or just 180 meters of books every day. If you can spend 4h/day to read you just need to read 45 meters of books an hour or 1500 bph (Books Per Hour). You are probably reading at 0.025-0.1 books per hour. But if you practice, you might have a chance? If each book contains 250 pages. And each page is on average 20 cm tall. And you can spend 4h on average each day reading. That means you have to read text at a speed of 187.5 km/h to keep up. However that is probably a bit too fast, since there is usually some white space on each page of a book so lets round it down to 150km/h. According to Stephen Hawking “if you stacked the new books being published next to each other, at the present rate of production you would have to move at ninety miles an hour just to keep up with the end of the line.” 90mph equals 144.841 km/h. I say, Stephen Hawking was a bit too generous. I calculated the reading speed needed on my own and came to the same approximately the same conclusion as Hawking. Yes I know. Great minds think a like, but since I think my calculation was a bit better. It must mean I'm a bit smarter than him, right? Not that I would want to flatter myself, just a little bit smarter is enough. Now I just need to study physics so I can solve how we may travel back in time to keep up reading all the books or make an alternative world with less authors so we can keep up reading. If you like me, think this situation is unacceptable. You too may sign my petition to forbid anyone from writing more than one book of 250 pages in their entire life for the next 2000-10.000 years. So we can catch up with reading all those books. You will have to excuse me but I tried to set my goal of reading 2.3 million books next year here on goodreads. But it only allowed to set the counter to 99 thousand so unfortunately it will have to wait until they fix this. I suspect the limit is there by intent. Since if everyone read all the books published each year and a few millions more, goodreads would not be needed. Their business model is based on you not reading 150kmbookpages/h. I have contacted customer support, unfortunately they did not take my suggestion seriously, if you could please help me and also email them then hopefully they will come to their senses and fix this once they see there is a demand. (Don't do this, it's just a joke.) In the meantime I will just go back to reading 10-20 books a year.

…After seventeen minutes of panicky crowds destroying everything in their path, Eric could distinguish, despite all the chaos and hellish noise, the slight buzz of a second plane. He started counting to himself, watching the blazing inferno at the North Tower: One, two, three, four, five, six, seven… The second Boeing glided into the South Tower, WTC-2, and it seemed to Eric that this plane was flying slowly, that its impact was a soft one… Due to the pandemonium all around, the impact itself seemed not to be as loud as the first hit. Still, in a moment the second twin was also blazing. Both skyscrapers were on fire now. Novack looked up again at what had happened a minute before: the terror attack of the century. Then he started walking fast down Church Street, away from the huge buildings that were now on fire. He knew that in about an hour, the South Tower was to collapse completely, and half an hour after that, the same was to happen to the North Tower, which was also weakened by the impact. He knew there were tons of powerful Thermate in both buildings. Over the course of the previous two months, some fake repairmen had brought loads of it into the towers and put them in designated places around the trusswork. It was meant to make buildings collapse like card towers, which would only happen when the flames reached a certain point. The planes had started an unstoppable countdown as soon as they hit the buildings: these were the last minutes of their existence. Next in line was the third building: 7 WTC, which stood north of the Twin Towers. It counted forty-seven floors, and it too was stuffed with Thermate. Novack started getting concerned, however, that the third plane seemed to be late. Where’s the third plane? Why is it late? It’s already fifty minutes after the first impact, and they were supposed to hit the three targets with a time lag of about twenty minutes. Where are you, birdie number three? You are no less important than the first two, and you were also promised to my clients… People were still running in all directions, shouting and bumping into each other. Sirens wailed loudly, heartrendingly; ambulances were rushing around, giving way only to firefighters and emergency rescue teams. Suddenly hundreds of policemen appeared on the streets, but it seemed that they didn’t really know what they were supposed to do. They mostly ran around, yelling into their walkie-talkies. At Thomas Street, Eric walked into a parking lot: the gate arm was up and the security guy must have left, for the door of his booth stood wide open… …Two shots rang out simultaneously during the fifth and the longest second. They were executed synchronously, creating a single, stinging, deadly sound. The bullet from the sixth floor of the book depository went straight up into the sky, as planned. The second bullet shot out of a sniper rifle, held confidently in the arms of a woman behind the hedge, on the grassy knoll. It was her bullet that struck the head of the 35th US president, John Fitzgerald Kennedy. The woman walked quickly down the grassy knoll. Stepping only about five meters away, she put her rifle into a baby pram waiting there, with a real six-month-old baby boy whimpering inside it. She put on thick glasses and started walking away, exhibiting no haste. Only thirty seconds after the second shot, the woman was gone, nowhere to be seen… After the second or, rather, the third shot, the one from the knoll, President Kennedy’s head was tossed back. Jackie somehow managed to crawl onto the back hood of the car. A security agent from the escort car had already reached them. The motorcade picked up speed and disappeared under the overpass. Zapruder’s camera kept whirring for some seconds. He must have filmed the whole operation – that is, the assassination of an acting US president. But now he simply stood there without saying a word, completely dumbfounded...

Future destinations in our solar system neighborhood include potential probe missions to a few moons of Jupiter, Saturn, and Neptune -- mainly by virtue of them being possible candidates for life, with their large oceans buried beneath icy crusts, plus intense volcanic activity. But getting humans to explore these possibly habitable worlds is a big issue in space travel. The record for the fastest-ever human spaceflight was set by the Apollo 10 crew as they gravita­tionally slingshotted around the Moon on their way back to Earth in May 1969. They hit a top speed of 39,897 kilo­meters per hour (24,791 miles per hour); at that speed you could make it from New York to Sydney and back in under one hour. Although that sounds fast, we've since recorded un-crewed space probes reaching much higher speeds, with the crown currently held by NASA's Juno probe, which, when it entered orbit around Jupiter, was traveling at 266,000 kilometers per hour (165,000 miles per hour). To put this into perspective, it took the Apollo 10 mission four days to reach the Moon; Opportunity took eight months to get to Mars; and Juno took five years to reach Jupiter. The distances in our solar system with our current spaceflight technology make planning for long-term crewed explora­tion missions extremely difficult." "So, will we ever explore beyond the edge of the solar system itself? The NASA Voyager 1 and 2 spacecraft were launched back in 1977 with extended flyby missions to the outer gas giant planets of Jupiter and Saturn. Voyager 2 even had flyby encounters with Uranus and Neptune -- it's the only probe ever to have visited these two planets. "The detailed images you see of Uranus and Neptune were all taken by Voyager 2. Its final flyby of Neptune was in October 1989, and since then, it has been traveling ever farther from the Sun, to the far reaches of the solar sys­tem, communicating the properties of the space around it with Earth the entire time. In February 2019, Voyager 2 reported a massive drop off in the number of solar wind particles it was detecting and a huge jump in cosmic ray particles from outer space. At that point, it had finally left the solar system, forty-one years and five months after being launched from Earth. "Voyager 1 was the first craft to leave the solar system in August 2012, and it is now the most distant synthetic object from Earth at roughly 21.5 billion kilometers (13.5 billion miles) away. Voyager 2 is ever so slightly closer to us at 18 billion kilometers (11 billion miles) away. Although we may ultimately lose contact with the Voyager probes, they will continue to move ever farther away from the Sun with nothing to slow them down or impede them. For this reason, both Voyager crafts carry a recording of sounds from Earth, including greetings in fifty-five differ­ent languages, music styles from around the world, and sounds from nature -- just in case intelligent life forms happen upon the probes in the far distant future when the future of humanity is unknown.

Speed is measured as distance divided by time (miles per hour or meters per second). For the speed of light to remain constant, distance and time have to change. Let’s go back now to Galileo’s shipboard experiment, using a beam of light instead of a stone. On a boat that’s moving at a uniform speed across the water, shine a flashlight down the mast, and it will strike the deck at the base of the mast. The observer on the dock agrees with that. But from her vantage point on the dock, if she had a precision measuring tool, she would see the light travel a tiny extra distance, the distance the ship has moved in the time it took the light to reach the bottom of the mast. But the speed of light, which is measured in meters per second—again, distance divided by time—is a constant. So if the observer on the dock finds that light traveled an extra distance, the only way its speed can remain constant is if the light also took a longer time to travel. Time, therefore, is not immutable. The duration of time— measured as the ticks of a clock—is dif­ferent for observers who move at dif­ferent speeds. Each sees the other’s clock slow down. Even more strangely, distance is not absolute either; it appears to contract in the direction of motion.

Music is a universe of sound, constantly expanding and dividing. Compositions are carved into movements and passages. A half note branches off into quarter notes, sixteenth notes—the same tone, yet held for a different duration, a different effect. A harmony of multiple notes, a counterpoint of multiple melodies, an orchestra of multiple instruments: separate spheres, playing in parallel. “A composer must make order out of this hopeless profusion of noise. To play every note at once—one big, all-encompassing dot—would produce chaos. To play none would produce silence. But to space them out artfully on a staff of time: that would produce a masterpiece. “And so the composer splits the piece into measures and meter. The notes are held tight within bar lines, told when to ring out and when to die out, when to attack and when to decay. They are given finite boundaries. *You will last for eight breaths, and no more.* To them, time is fixed; to the composer, it is fluid. She could speed it up, slow it down, change duple meter to triple meter or a march to a waltz. She knows that the beauty lies not in how long the note lasts, but in the sound that it makes while it does. “Maybe, the woman thinks, our composer has done the same with us. Lest eternity seem too long and infinity too loud, she imposes measures on our existence, divides it into years, generations, incarnations. We count beats and birthdays. We emerge from the silence, and we fade back into it. This is not a punishment or a curse, any more than it is to assign a time signature to a song. After all, if there is no beat, how can there be a dance? “She does not do this to make us suffer. She does this to make us music.

Birds that are startled frequently try to take off and fly toward what looks like open space, which is often how they end up hitting windows. If the window is close enough, the bird won’t have time to get up enough speed to injure itself too badly, which is why the Audubon Society recommends that if you can’t put bird feeders more than 10 meters away from your window, you should put them closer than 1 meter.

The significance of shared arousal was demonstrated in an ingenious experiment designed by researcher Joshua Conrad Jackson and published in the journal Scientific Reports in 2018. Jackson and his colleagues set out “to simulate conditions found in actual marching rituals”—which, they noted, “required the use of a larger venue than a traditional psychology laboratory.” They chose as the setting for their study a professional sports stadium, with a high-definition camera mounted twenty-five meters above the action. After gathering 172 participants in the stadium and dividing them into groups, the experimenters manipulated their experience of both synchrony and arousal: one group was directed to walk with their fellow members in rank formation, while a second group walked in a loose and uncoordinated fashion; a third group speed-walked around the stadium, boosting their physiological arousal, while a fourth group strolled at a leisurely pace. Jackson and his collaborators then had each group engage in the same set of activities, asking them to gather themselves into cliques, to disperse themselves as they wished across the stadium’s playing field, and finally to cooperate in a joint task (collecting five hundred metal washers scattered across the field). The result: when participants had synchronized with one another, and when they had experienced arousal together, they then behaved in a distinctive way—forming more inclusive groups, standing closer to one another, and working together more efficiently (observations made possible by analyzing footage recorded by the roof-mounted camera). The findings suggest that “behavioral synchrony and shared physiological arousal in small groups independently increase social cohesion and cooperation,” the researchers write; they help us understand “why synchrony and arousal often co-occur in rituals around the world.

Finally, we found someone who had stopped. It wasn’t for us, but only because he hadn’t made it that far. We rounded a bend to see a gray-haired guy getting out of his van, having pulled to the side to take a piss. He was still about fifty meters away. We picked up speed and yelled, but he was already heading into the woods. “Must have a shy bladder,” Corey said. True. With these back roads, most guys settled for walking around their vehicle for privacy. Some didn’t even do that. “He left the van running,” Corey said. “No,” Daniel said. “Yes, we shouldn’t take his ride,” Corey said. “But we’re exhausted, out of food, nearly out of water, and that van is our best chance. Do you really want to just trust he’ll help us?” “No, I want to make sure he will. I’ll try using my powers. If that fails, we’ll have to resort to…other incentives.” Daniel flexed his arms. “We can’t take his ride, though. We don’t know how far he might need to walk to the nearest town. You two hang back,” he said to Corey and Sam. “Maya, make Kenjii stay with them.” “Excuse me?” Corey said. “Sam and I aren’t going to scare--” “Four teenagers and a dog will scare any old guy,” Daniel said. “So will two guys. So will…” He glanced at Sam. “Thanks,” she said. “You know what I mean. Maya’s friendly. And she can keep her cool.” “I’m not sure that’s any less insulting,” Sam muttered. But she waved us ahead.

Most readers might now expect a closing paragraph in which I extoll the nonscientific benefits of manned space exploration: the thrill of the exploration of the unknown; the idea that mankind needs new frontiers if it is not to stagnate; the worry that if mankind is stuck on one planet, a disaster could destroy us. These are appealing ideas. But manned space exploration clearly will not happen unless we find better ways of getting off-planet and creating homelike places elsewhere. I’d like to construct an analogy: we are in the same situation with regard to manned spaceflight today as Charles Babbage was with respect to computing in the 1860s. He invented the basic ideas for the modern computer and tried to implement them using the mechanical technology of his day. The technology was marginally not good enough to allow his analytical engine to be built. We seem to be in the same situation today: chemical rockets with exhaust speeds of a few thousand meters per second are marginally good enough to launch unmanned probes traveling slowly through the Solar System but are completely inadequate for manned missions.

…Two shots rang out simultaneously during the fifth and the longest second. They were executed synchronously, creating a single, stinging, deadly sound. The bullet from the sixth floor of the book depository went straight up into the sky, as planned. The second bullet shot out of a sniper rifle, held confidently in the arms of a woman behind the hedge, on the grassy knoll. It was her bullet that struck the head of the 35th US president, John Fitzgerald Kennedy. The woman walked quickly down the grassy knoll. Stepping only about five meters away, she put her rifle into a baby pram waiting there, with a real six-month-old baby boy whimpering inside it. She put on thick glasses and started walking away, exhibiting no haste. Only thirty seconds after the second shot, the woman was gone, nowhere to be seen… After the second or, rather, the third shot, the one from the knoll, President Kennedy’s head was tossed back. Jackie somehow managed to crawl onto the back hood of the car. A security agent from the escort car had already reached them. The motorcade picked up speed and disappeared under the overpass. Zapruder’s camera kept whirring for some seconds. He must have filmed the whole operation – that is, the assassination of an acting US president. But now he simply stood there without saying a word, completely dumbfounded..

Goethe refused to view color as a static quantity, to be measured in a spectrometer and pinned down like a butterfly to cardboard. He argued that color is a matter of perception. “With light poise and counterpoise, Nature oscillates within her prescribed limits,” he wrote, “yet thus arise all the varieties and conditions of the phenomena which are presented to us in space and time.” The touchstone of Newton’s theory was his famous experiment with a prism. A prism breaks a beam of white light into a rainbow of colors, spread across the whole visible spectrum, and Newton realized that those pure colors must be the elementary components that add to produce white. Further, with a leap of insight, he proposed that the colors corresponded to frequencies. He imagined that some vibrating bodies—corpuscles was the antique word—must be producing colors in proportion to the speed of the vibrations. Considering how little evidence supported this notion, it was as unjustifiable as it was brilliant. What is red? To a physicist, it is light radiating in waves between 620 to 800 billionths of a meter long. Newton’s optics proved themselves a thousand times over, while Goethe’s treatise on color faded into merciful obscurity.

It being the digital age and all, I can comprehend why one would choose the mobile phone, the most convenient and indispensable device , as a tool to be insolent towards antediluvian people like me who still have not lost faith in down-to-earth face-to-face interactions. It always begins with an impulsive need to pick up the phone and browse through apps. This need then, with the speed of the wind would gain a sense of immediacy whereupon, Mr./Ms. Presumptuous would make unconvincing excuses about having to take a call or text to a family member to check on his/her welfare. Leaving me in the middle of an interesting development that I am so willing to share, Mr./Ms. Presumptuous walks few meters away from where I am seated and comes back twenty minutes later only to steer the conversation away to a subject that he/she fancies.

chaos in her eyes Sitting with Christine, thinking about the chaos in her eyes, his emotional chaos, plotting to lure her out for a weekend of love, he wished in a chaotic, physical logic,” I wish I could count the number of causes and their probabilities that affect your feelings about me and that will determine what kind of answer I get if I ask you out for a date.” -What? What is that you just said? (An internal voice). By knowing the causes and the probabilities of the order in which they occur, you predict emotions Is that possible? Can we treat human emotions like the weather? Are there sensors to measure our emotions across time points in our history from which we can predict our future actions and their impact on us and others? Is there a computer with enormous capacity that can collect, analyze, and predict them? Do human emotions fall within this randomness? Throughout their history, physicists have rejected the idea of a relationship between human emotions and the surrounding world. Emotions are incomprehensible, they cannot be expected, what cannot be expected cannot be measured, what cannot be measured cannot be formulated into equations, and what cannot be formulated into equations, screw it, reject it, get rid of it, it is not part of this world. These ideas were acceptable to physicists in the past before we knew that we can control the effect of randomness to some extent through control sciences, and predict it by collecting a huge amount of data through special sensors and analyzing it. What affects when a plane arrives? Wind speed and direction? Our motors compensate for this unwanted turbulence. A lightning strike could destroy it? Our lightning rods control this disturbance and neutralize its danger. Running out of fuel? We have fuel meter indicators. Engine failure? We have alternative solutions for an emergency landing. All fall under the category of control sciences, But what about the basic building blocks of an airplane model during its flight? Humans themselves! A passenger suddenly felt dizzy, and felt ill, did the pilot decide to change his destination to the nearest airport? Another angry person caused a commotion, did he cause the flight to be canceled? Our emotions are part of this world, affect it, and can be affected by, interact with. Since we can predict chaos if we have the tools to collect, measure, and analyze it, and since we can neutralize its harmful effects through control science, thus, we can certainly do the same to human emotions as we do with weather and everything else that we have been able to predict and neutralize its undesirable effect. But would we get the desired results? nobody knows… -“Not today, not today, Robert”, he spoke to himself. – If you can’t do it today, you can’t do it for a lifetime, all you have to do now is simply to ask her out and let her chaos of feelings take you wherever she wants. Unconsciously, about to make the request, his phone rang, the caller being his mother and the destination being Tel Aviv. Standing next to Sheikh Ruslan at the building door, this wall fascinated him. -The universe worked in some parts of its paint even to the point of entropy, which it broke, so it painted a very beautiful painting, signed by its greatest law, randomness. If Van Gogh was here, he would not have a nicer one. Sheikh Ruslan knocked on the door, they heard the sound of footsteps behind him, someone opened a small window from it, as soon as he saw the Sheikh until he closed it immediately, then there was a rattle in the stillness of the alley, iron locks opening. Here Robert booked a front-row seat for the night with the absurd, illogic and subconscious.

All Hadza women dig, but grandmothers dig more than mothers in part because they don’t have to nurse or spend as much time taking care of little ones. According to measurements by Kristen Hawkes and colleagues, a typical Hadza mother forages about four hours a day, but grandmothers forage on average five to six hours a day.18 On some days they dig less and spend more time collecting berries, but overall they work longer hours than mothers do. And just as grandmothers spend about seven hours every day foraging and preparing food, grandfathers continue to hunt and to collect honey and baobab fruits, traveling just as far on most days as younger men do. According to the anthropologist Frank Marlowe, “Old men are the most likely to fall out of tall baobab trees to their deaths, since they continue to try to collect honey into old age.”19 How many elderly Americans dig several hours a day, let alone climb trees and hunt animals on foot? We can, however, compare how much Americans and Hadza walk. A study of thousands found that the average twenty-first-century woman in the United States aged eighteen to forty walks 5,756 steps a day (about two to three miles), but this number declines precipitously with age, and by the time they are in their seventies, American women take roughly half as many steps. While Americans are half as active in their seventies as in their forties, Hadza women walk twice as much per day as Americans, with only modest declines as they age.20 In addition, heart rate monitors showed that elderly Hadza women actually spent more of their day engaged in moderate to vigorous activity than younger women who were still having children.21 Imagine if elderly American women had to walk five miles a day to shop for their children and grandchildren, and instead of pulling items off the shelves, they had to dig for several hours in hard, rocky soil for boxes of cereal, frozen peas, and Fruit Roll-Ups. Not surprisingly, hard work keeps elderly hunter-gatherers fit. One of the most reliable measures of age-related fitness is walking speed—a measure that correlates strongly with life expectancy.22 The average American woman under fifty walks about three feet per second (0.92 meter per second) but slows down considerably to two feet per second (0.67 meter per second) by her sixties.23 Thanks to an active lifestyle without retirement, there is no significant age-related decline in walking speed among Hadza women, whose average pace remains a brisk 3.6 feet per second (1.1 meters per second) well into their seventies.24 Having struggled to keep up with elderly Hadza grandmas, I can attest they maintain a steady clip even when it is blisteringly hot. Older Hadza men also walk briskly.

Dorsal The dorsal column system runs through the “white matter” of the spinal cord. It is white because its axons are insulated with white, fatty myelin, which increases their transmission speed considerably. Their speed—from forty to seventy meters per second—is also enhanced by the fact that there are few synapses to cross from the peripheral sensory ending to the cortex. Like the corticospinal motor pathway, these fibers have a high degree of spatial organization throughout the length of the spinal cord, and like the corticospinal pathway, they faithfully map the relationships of their origins onto the cortex. This system transmits touch sensations which have precise localizations and fine gradations of intensity, phasic or vibratory sensations, kinesthetic sensations related to body parts in motion, and sensations which have to do with fine distinctions of pressure.

At walking speed, a twenty-kilogram dog like you has a wavelength of about 10-35 meters. You need your wavelength to be comparable to the size of the tree—maybe ten centimeters—in order to diffract around it, and you’re thirty-four orders of magnitude off.

I’ll just change my wavelength by changing my momentum. I can run very fast.” “Nice try, but the wavelength gets shorter as you go faster. To get your wavelength up to the millimeter or so you’d need to diffract around a tree, you’d have to be moving at 10-30 meters per second, and that’s impossibly slow. It would take a billion years to cross the nucleus of an atom at that speed, which is way too slow to catch a bunny.

The company's engineers realized the best approach was to shoot a tiny ball of tin measuring thirty-millionths of a meter wide moving through a vacuum at a speed of around two hundred miles per hour. The tin is then struck twice with a laser, the first pulse to warm it up, the second to blast it into a plasma with a temperature around half a million degrees, many times hotter than the surface of the sun. This process of blasting tin is then repeated fifty thousand times per second to produce EUV light in the quantities necessary to fabricate chips.
