What Can We Learn From Degas About the Nature of Time? On a recent Saturday morning, my wife, Susan, and I slipped into the city to visit the Metropolitan Museum of Art, a place we hadn’t gone together since before our sons were born.
The crowds hadn’t yet descended and for an hour or so we wandered around and absorbed the cavernous hush of art. We separated for a bit, together but apart; while Susan roamed among the Manets and Van Goghs I slipped into a small side gallery, not much larger than a subway car, that held a series of glass cases with small bronze sculptures by Degas. There were a few busts and several horses in stride and the figure of a woman stretching, a small bronze rising to her feet and curling her left arm upward as if waking from a long nap.
At the end of the gallery, in one long case, were two dozen ballerinas in various states of motion or repose. One dancer was examining the sole of her right foot; another was putting on her stocking; a third stood with her right leg forward and her hands behind her head. The Secret Life of Time. Some nights—more than I like, lately—I wake to the sound of the bedside clock.
The room is dark, without detail, and it expands in such a way that it seems as if I’m outdoors, under an empty sky, or underground, in a cavern. I might be falling through space. I might be dreaming. I could be dead. Only the clock moves, its tick steady, unhurried. I’m tempted to look at the clock, but I already know that it’s the same time it always is: 4 A.M., or 4:10 A.M., or once, for a disconcerting stretch of days, 4:27 A.M. In 1917, the psychologist Edwin G. It may also be a simple matter of induction: it was 4:27 A.M. when I last woke at whatever hour this is, so that’s what time it is now. And, once the ghost gets thinking, there is much to think about—most of all, how little time I have in which to do all the things I’m thinking about and how behind I am. As worried as I am in these waking moments, I also find them oddly calming.

Apple purchased a 3D imaging company called PrimeSense in 2013, and now has released a phone with two camera lenses and the ability to perceive depth of field, the base requirement for capturing 3D spaces and objects. Add that to the fact that Apple CEO Tim Cook has made several statements expressing his interest in augmented reality. So it’s natural to wonder if the iPhone 7 Plus represents Apple’s first steps toward some augmented reality product that could place 3D objects over a real-world space. Microsoft’s HoloLens headset already does just that, as does Lenovo’s PHAB 2 Pro, the first product to embody Google’s Project Tango AR technology. The iPhone 7 Plus features a 28mm wide angle lens and an additional 56mm lens (which technically is not the telephoto lens that Apple’s promo materials suggest, but rather something like a "portrait" lens).
A Debate Over The Physics Of Time. Einstein once described his friend Michele Besso as “the best sounding board in Europe” for scientific ideas.
They attended university together in Zurich; later they were colleagues at the patent office in Bern. When Besso died in the spring of 1955, Einstein — knowing that his own time was also running out — wrote a now-famous letter to Besso’s family. “Now he has departed this strange world a little ahead of me,” Einstein wrote of his friend’s passing. “That signifies nothing. The Psychology of Time and the Paradox of How Impulsivity and Self-Control Mediate Our Capacity for Presence.
“Reality is never and nowhere more accessible than in the immediate moment of one’s own life,” Kafka once told a teenage friend.
“It’s only there that it can be won or lost.” The great Russian filmmaker Andrei Tarkovsky believed that what draws us to film is the gift of time — “time lost or spent or not yet had.” From the moment we are born to the moment we take our last breath, we battle with reality under the knell of this constant awareness that we are either winning or losing time. We long for what T.S. Why does time pass? Timeless. Redefining Time installation. Jay Mark Johnson’s very unusual camera emphasizes time over space. Jay Mark Johnson.
The abstract-seeming images here are not the result of some wacky Photoshopping. Jay Mark Johnson’s photos are actually incredibly precise. The reason they look like this is because he uses a slit camera that emphasizes time over space. Whatever remains still is smeared into stripes, while the motion of crashing waves, cars and a Tai Chi master’s hands are registered moment by moment, as they pass his camera by. Like an EKG showing successive heartbeats, the width of an object corresponds not to distance or size, but the rate of movement. Yes, it’s a confusing concept. This unique look is possible because the fixed-position slit camera registers only a vertical sliver of a scene. If you are still having trouble with this idea, try cutting out a tiny slit of paper and holding it up to your eye. When Will Time End? Krishnamurti & David Bohm The Future of Humanity 11.

By Tam Hunt Saturday, December 31, 2011 In any attempt to bridge the domains of experience belonging to the spiritual and physical sides of our nature, time occupies the key position. —Arthur Stanley Eddington, 1928 Everything is determined, the beginning as well as the end, by forces over which we have no control. —Albert Einstein Even very smart people can be wrong. Alan Watts - Time (as social institution) Philosophy of Time part 1 of 3. Nature of time. Time is the most fundamental aspect of our experience, and yet it remains mysterious in many ways.
A longstanding problem is time's arrow – the directionality displayed by most physical processes, for example, clocks run down, organisms age, stars burn out. The laws of physics are symmetric in time, so the appearance of asymmetry from symmetry can be understood only by looking outside the system. Ultimately that leads to cosmology. Syntropy. Time: Reversible or Irreversible? - Fringe Science. Classical physics says time is reversible because its laws hold true whether time flows forward or backward.
Thermodynamics says time only flows forward, because were it to reverse, entropy of an isolated system could decrease which would violate the second law of thermodynamics. So is time reversible or irreversible? The answer cannot be deduced from either classical physics or thermodynamics because both are flawed in their assumptions. Classical Systems are Timeless Classical physics only deals with deterministic systems whose past, present, and future are entirely contained in a single timeless equation.
Irreversibility. Irreversibility According to the second law of thermodynamics, the entropy (a measure of disorder or chaos) of an isolated system (one that does not exchange matter, energy, or information with its environment) will remain unchanged for reversible processes but will increase for irreversible processes.
Thus irreversible systems, including all living systems, tend to become chaotic as their entropy increases. Irreversible process. In thermodynamics, a change in the thermodynamic state of a system and all of its surroundings cannot be precisely restored to its initial state by infinitesimal changes in some property of the system without expenditure of energy. A system that undergoes an irreversible process may still be capable of returning to its initial state; however, the impossibility occurs in restoring the environment to its own initial conditions. An irreversible process increases the entropy of the universe. However, because entropy is a state function, the change in entropy of a system is the same whether the process is reversible or irreversible.
The second law of thermodynamics can be used to determine whether a process is reversible or not. Many biological processes that were once thought to be reversible have been found to actually be a pairing of two irreversible processes. New Theory Claims that Time is Not the 4th Dimension. Einstein never interpreted time "t" as a fourth dimension of space. Space is not 3D + T, space is 4D. With clocks we measure numerical order of material change. This numerical order is the only time that exists in a physical world.
With this approach all immediate information transfers of quantum physics are explained in a more appropriate way. 4D space is a medium of quantum information transfers. The Quantum Mechanics of Fate - Issue 9: Time. “The objective world simply is, it does not happen,” wrote mathematician and physicist Hermann Weyl in 1949. From his point of view, the universe is laid out in time as surely as it is laid out in space. Time does not pass, and the past and future are as real as the present. If your common sense rebels against this idea, it is probably for a single reason: the arrow of causality. Events in the past cause events in the present which cause events in the future. Controversially, Physicist Argues Time Is Real. NEW YORK — Is time real, or the ultimate illusion?
Most physicists would say the latter, but Lee Smolin challenges this orthodoxy in his new book, "Time Reborn" (Houghton Mifflin Harcourt, April 2013), which he discussed here Wednesday (April 24) at the Rubin Museum of Art. In a conversation with Duke University neuroscientist Warren Meck, theoretical physicist Smolin, who's based at Canada's Perimeter Institute for Theoretical Physics, argued for the controversial idea that time is real. "Time is paramount," he said, "and the experience we all have of reality being in the present moment is not an illusion, but the deepest clue we have to the fundamental nature of reality. " [Album: The World's Most Beautiful Equations] Smolin said he hadn't come to this concept lightly.
