How Visionaries in Visualization Moved Science Forward 2016-05-06T04:00:00Z That is, according to quantum theory, a large object could be in two quantum states at the same time. Quantum leap 2015-12-22T05:00:00Z According to quantum theory, minuscule things behave nothing like everyday objects. Massive neutrino experiment undermines our sense of reality 2016-07-12T04:00:00Z Einstein’s “miraculous year” of 1905, in which he not only deduced special relativity but also kick-started quantum theory and published several other ground-breaking papers, was an unrivalled creative burst. There’s no space for today’s young Einsteins | Philip Ball 2016-02-12T05:00:00Z In quantum theory everything is, at some scale, bitty. The most beautiful theory 2015-11-25T05:00:00Z Galileo’s objection to it was like Einstein’s to the quantum theory: that the moon working an occult influence on the oceans was obviously magical nonsense. Is Science Kind of a Scam? 2015-11-30T05:00:00Z “I would not hesitate for a minute,” says physicist Bartłomiej Czech of Stanford University in California, “to call the connections between quantum theory and gravity that have emerged in the last ten years revolutionary.” The quantum source of space-time 2015-11-15T05:00:00Z IN THE 1930s Albert Einstein was greatly troubled by a phenomenon that emerged from quantum theory. Hidden no more 2015-10-21T04:00:00Z Einstein was deeply unhappy with the uncertainty introduced by quantum theory and described the implications of quantum theory as akin to God playing dice. Quantum Theory Experiment Said to Prove ‘Spooky’ Interactions 2015-10-21T04:00:00Z Dr Hawking went on to bring elements of quantum theory into science’s understanding of the black hole. The most beautiful theory 2015-11-25T05:00:00Z He believed that there must exist hidden aspects of reality, not yet recognized within the conventional formulation of quantum theory, which would restore Einstein Sanity. Einstein's Parable of Quantum Insanity 2015-09-23T04:00:00Z Einstein notoriously disliked the inherent randomness in quantum theory—which he described as God playing dice with the universe—and he was not alone. Book Review: Einstein's Dice and Schrödinger's Cat 2015-09-06T04:00:00Z According to quantum theory, if Alice and Bob tilt their analyzers to different angles, they should no longer see perfect correlations in their measurements. More evidence to support quantum theory’s ‘spooky action at a distance’ 2015-08-28T04:00:00Z He said quantum theory necessitated “spooky action at a distance,” and he refused to accept the notion that the universe could behave in such a strange and apparently random fashion. Quantum Theory Experiment Said to Prove ‘Spooky’ Interactions 2015-10-21T04:00:00Z The theory explained, to begin with, remarkably little, and unlike quantum theory, the only comparable revolution in 20th-century physics, it offered no insights into the issues that physicists of the time cared about most. The most beautiful theory 2015-11-25T05:00:00Z First of all, note that what Einstein describes as insanity is, according to quantum theory, the way the world actually works. Einstein's Parable of Quantum Insanity 2015-09-23T04:00:00Z But owing in great measure to Dr. Bekenstein’s work and to the application of quantum theory, that view has been substantially altered. Jacob Bekenstein, towering theoretical physicist who studied black holes, dies at 68 2015-08-27T04:00:00Z The Danish physicist Niels Bohr once said that anyone who was not shocked by quantum theory did not understand it. Bernard d’Espagnat, French Physicist, Dies at 93 2015-08-15T04:00:00Z In particular, he hated the indeterminacy of the full quantum theory as it developed in the 1920′s. How Quantum Randomness Saves Relativity 2015-08-11T04:00:00Z Drawing on a controversial interpretation of quantum theory, they propose an Escher-like symbiosis. Humankind’s Existentially Lucky Numbers 2015-06-22T04:00:00Z But as the predictions of conventional quantum theory, free of hidden variables, have gone from triumph to triumph, the wiggle room where one might accommodate such variables has become small and uncomfortable. Einstein's Parable of Quantum Insanity 2015-09-23T04:00:00Z Dr. Nash was working at the time at the Massachusetts Institute of Technology and was studying quantum theory. John F. Nash Jr. dies; Nobel laureate’s life story inspired ‘A Beautiful Mind’ 2015-05-24T04:00:00Z It was Albert Einstein, both a founder of quantum theory and a skeptic of it, who showed just how weird the theory really was. Bernard d’Espagnat, French Physicist, Dies at 93 2015-08-15T04:00:00Z “If we tell the public that quantum theory is weird, we better go out and test that's actually true,” he says. Quantum physics: What is really real? 2015-05-19T04:00:00Z Einstein’s reaction to quantum theory was mostly an argument of dissatisfaction– quantum predictions offended a hard-to-define intuition about how the world “ought” to work, but he never managed a solid alternative. The Role Of Philosophy In Physics 2015-05-11T04:00:00Z Starting in the late 1920s, one of his primary goals was a deterministic alternative to probabilistic quantum theory, as developed by Niels Bohr, Werner Heisenberg, Max Born, and others. “Albert is an old fool”: Einstein vs Schrödinger in battle of the Nobel laureates 2015-04-18T04:00:00Z Because he was not mathematically adept, he could not get to grips with relativity or quantum theory. How 2 Pro-Nazi Nobelists Attacked Einstein’s "Jewish Science" 2015-02-13T05:00:00Z There are many interpretations of quantum theory; in all of them, he said, the world is real, but so in most of them is spooky action at a distance, now enshrined in technology as “entanglement.” Bernard d’Espagnat, French Physicist, Dies at 93 2015-08-15T04:00:00Z Which of quantum theory's many interpretations — if any — is correct? Quantum physics: What is really real? 2015-05-19T04:00:00Z Einstein, Podolsky, and Rosen argued that this points to a fundamental incompleteness in quantum theory– that there must be some deeper reality in which those measurement outcomes are defined in advance. The Role Of Philosophy In Physics 2015-05-11T04:00:00Z Although he realized that quantum theory was experimentally successful, he judged it incomplete. “Albert is an old fool”: Einstein vs Schrödinger in battle of the Nobel laureates 2015-04-18T04:00:00Z Bell’s paper made important claims about quantum entanglement, one of those captivating features of quantum theory that depart strongly from our common sense. Is Quantum Entanglement Real? 2014-11-14T05:00:00Z The penumbra of uncertainty and randomness with which quantum theory endowed nature on the smallest scales would in effect pierce the black hole’s previously inviolable surface.

Sounds like the light idea 2014-10-16T04:00:00Z When physicists first formulated quantum theory they realized that an electron in an atom can jump from one energy level to another, giving off or absorbing light. Fact or Fiction?: Energy Can Neither Be Created Nor Destroyed 2014-08-05T04:00:00Z Albert Einstein sneered that if the equations of quantum theory predicted such nonsense, so much the worse for quantum theory. Is Quantum Entanglement Real? 2014-11-14T05:00:00Z That required a daunting calculation that would combine quantum theory with Einsteinian gravity, twin poles of theoretical physics thought until then to be mathematically incompatible. Stephen Hawking’s Movie Life Story Is Not Very Scientific 2014-10-27T04:00:00Z Debates over the nature of reality go back to physicists' realization in the early days of quantum theory that particles and waves are two sides of the same coin. Quantum physics: What is really real? 2015-05-19T04:00:00Z The great American physicist Richard Feynman said that quantum theory “describes nature as absurd from the point of view of common sense.” Developments in Quantum Physics Are About to Transform Our Daily Lives Einstein was trying prove that quantum theory was flawed and he discovered and proved entanglement. Scientists Report Finding Reliable Way to Teleport Data 2014-05-29T04:00:00Z Bizarre as it may sound, even a minuscule amount of such coordination of the detectors’ settings would enable certain alternative theories to mimic the famous predictions from quantum theory. Is Quantum Entanglement Real? 2014-11-14T05:00:00Z According to inflation theory, the Bicep2 waves are magnified images of the hypothetical particles called gravitons that would transmit gravity in quantum theory. Out There: Ripples From the Big Bang 2014-03-24T21:55:26Z The interference pattern becomes closer to that predicted by standard quantum theory as the number of worlds increases. Quantum physics: What is really real? 2015-05-19T04:00:00Z This seeming impossibility is part of the mystery that lies at the heart of quantum theory, which even theoretical physicists say no one completely understands. NSA seeks to build quantum computer that could crack most types of encryption 2014-01-02T21:24:10Z Einstein and two other mathematicians actually proved that entanglement should exist if quantum theory was correct. Scientists Report Finding Reliable Way to Teleport Data 2014-05-29T04:00:00Z The entangled particles could be separated across the galaxy, and somehow, according to quantum theory, measurements on one particle should affect the behavior of the far-off twin faster than light could have traveled between them. Is Quantum Entanglement Real? 2014-11-14T05:00:00Z While some theorists have questioned whether quantum theory can ever be applied to gravity, Dr. Wilczek said last week that the new discovery “means gravity is quantized.” Out There: Ripples From the Big Bang 2014-03-24T21:55:26Z The Showdown Many physicists expect quantum theory to prevail. Physicists Eye Quantum-Gravity Interface 2013-11-05T21:15:00.387Z And, on a more profound level, it might reveal the structure of space-time in a future quantum theory of gravity — a breakthrough that would unify modern physics. Rethinking particle dynamics 2013-10-02T17:20:32.117Z I think you should make clear that besides denying entanglement, Einstein was the one who noticed that quantum theory implied it.. Scientists Report Finding Reliable Way to Teleport Data 2014-05-29T04:00:00Z In his article, Bell demonstrated that quantum theory requires entanglement; the strange connectedness is an inescapable feature of the equations. Is Quantum Entanglement Real? 2014-11-14T05:00:00Z Many physicists respond to this inner weirdness by retreating into the 'Copenhagen interpretation' articulated by Niels Bohr, Werner Heisenberg and their colleagues as they were putting quantum theory into its modern form in the 1920s. Physics: Quantum quest 2013-09-12T13:51:03.407Z The hypothesis arises from a fundamental postulate of quantum theory, which says that measuring a property of an object, such as its position, affects its state. Quantum Paradox Seen in Diamond 2013-08-20T21:45:01.427Z This was a breakthrough in combining general relativity, the gravity that curves the cosmos, with quantum theory, which describes the microscopic quirkiness inside it, but there was a big hitch. A Black Hole Mystery Wrapped in a Firewall Paradox 2013-08-12T20:46:10Z A Quantum of Solace Niels Bohr, the Danish physicist and philosopher-king of quantum theory, once said that great truth is a statement whose opposite is also a great truth.
