Indian-American Deepak Chopra is one of the most famous proponents of this approach. Many people who believe in paranormal phenomena and in certain “therapies” claim to be inspired by quantum physics. “Quantum physics might explain certain alternative therapies and other mysteries” Marine Joumard, Flammarion, Author provided 7. Lasers, maglev trains and MRI are just a few of the applications of quantum physics. Lasers, MRI in hospitals, LEDs, flash memory, hard disks – and above all else, the transistor and electronics – all of these technologies were invented by quantum physicists. Quantum physics is probably the most useful discipline in modern physics: once physicists understood how light, atoms and electrons worked, they were able to manipulate them. Einstein fully appreciated the relevance of quantum physics, he just had a few problems with some of its implications, especially as regards locality. Later, experiments on entanglement and violation of Bell’s theorem proved him wrong and showed the absence of hidden variables. This is what won him the Nobel Prize, in fact, not his work on the theory of relativity.Įinstein probably earned that reputation because of his discussions with Niels Bohr, especially on the idea of interpretation and quantum reality, as he didn’t accept the concept of nonlocality. In it, he proposed that light was made of small, individual and quantified bodies, called photons. Poor old Albert Einstein is often depicted as having been a virulent opponent of quantum physics, probably because of his famous quote, “God does not play dice with the universe.” Yet he wasn’t against it and what’s more, he created it! In 1905 Einstein wrote his foundational article, “On a Heuristic Viewpoint Concerning the Production and Transformation of Light”, based on the work of Max Planck. “Einstein was quantum physics’ worst enemy” Marine Joumard et al., Author provided 5. Experiments generally come first, except in very few cases. The highly productive “back and forth” exchanges between theory and practice are what physics is built on. Theories and concepts then emerged once again: duality, spin or superconductivity were introduced. Only later did brilliant theorists enter the scene, when Albert Einstein, Max Planck, Niels Bohr and others tried to provide explanations.įurther fundamental experiments followed, including electrons that bounced weirdly off nickel, silver atoms strangely deviated by a magnetic field, a perfectly conducting metal at low temperatures and so on. The entire history of quantum physics shows the exact opposite: at the very beginning, lab experiments threw up unexpected results, such as the photoelectric effect, black-body radiation, the light emission spectrum of atoms. “A few brilliant theorists came up with the entire concept of quantum physics” They just need to adapt their intuitions to this new field and its inherent paradoxes. Physicists do understand what they’re doing when they’re manipulating the quantum formalism. One of the leading lights in the field, Richard Feynman himself said: “I think I can safely say that nobody understands quantum mechanics.” But he then immediately added: “I am going to tell you what nature behaves like.” Niels Bohr, one of the founding fathers of the discipline, gives a good summary: “Those who are not shocked when they first come across quantum theory cannot possibly have understood it.” “Even scientists don’t really understand quantum physics” Both patterns are probability distributions in the sense that they are built up by individual particles traversing the apparatus, the paths of which are not individually predictable.Design makes it possible to imagine what quantum particles could be. \): Double-slit interference for electrons (a) and photons (b) is identical for equal wavelengths and equal slit separations.
