Nuclear fusion is what powers the Sun and the stars — unleashing huge amounts of energy through the binding together of light elements such as hydrogen and helium. If fusion power were harnessed directly on Earth, it could produce inexhaustible clean power, using seawater as the main fuel, with no greenhouse gas emissions, no proliferation risk, and no risk of catastrophic accidents.
Recently, the conversation about science’s wrongness has gone mainstream. You can read, in publications like Vox, the New York Times or the Economist, about how the research process is far from perfect — from the inadequacies of peer review to the fact that many published results simply can’t be replicated. The crisis has gotten so bad that the editor of The Lancet medical journal Richard Horton recently lamented, “Much of the scientific literature, perhaps half, may simply be untrue.”
“Spooky action at a distance” is how Albert Einstein described one of the key principles of quantum mechanics: entanglement. Entanglement occurs when two particles become related such that they can coordinate their properties instantly even across a galaxy. Think of wormholes in space or Star Trek transporters that beam atoms to distant locations. Quantum mechanics posits other spooky things too: … Read More
The values of two inherent properties of one photon – its spin and its orbital angular momentum – have been transferred via quantum teleportation onto another photon for the first time by physicists in China. Previous experiments have managed to teleport a single property, but scaling that up to two properties proved to be a difficult task, which has only … Read More
Quantum mechanics is often described as “weird” and “strange” because it abandons many of the intuitive traits of classical physics. For example, the ideas that the world is objective, is deterministic, and exists independent of measurement are basic features of classical theory, but do not always hold up in quantum theory. But what if it turns out that these intuitive ideas are not true features of classical physics, either? Would classical theory be just as weird as quantum theory?
