It's Easier to Observe the Failure of Local Realism than Previously Thought
(PhysOrg.com) -- Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly ...

Does the quantum wave function represent reality?
(Phys.org) -- At the heart of quantum mechanics lies the wave function, a probability function used by physicists to understand the nanoscale world. Using the wave function, physicists can calculate a system's ...

The 'mad' Egyptian scholar who proved Aristotle wrong
Ibn al-Haytham's 11th-century Book of Optics, which was published exactly 1000 years ago, is often cited alongside Newton's Principia as one of the most influential books in physics. Yet very little is known about the writer, ...

Don't have all the information? In the quantum world, that doesn't matter
(PhysOrg.com) -- When it comes to the rules of the quantum world, it seems that almost everything goes against intuition. In the case of the way ignorance of the whole implies ignorance of at least one of its parts, the situation ...

Two crystals linked by quantum physics
Physicists take a perverse pleasure in playing with the strangeness of the quantum world. That's how they have managed to entangle minuscule objects such as photons. After specific manipulations, they persuade two photons ...
