Supersymmetry. True? False? Does it matter?
A beautiful but unproved theory of particle physics is withering in the harsh light of data. For decades, many particle physicists have devoted themselves to the beloved theory, known as supersymmetry. But it’s beginning to seem that the zoo of new particles that the theory predicts – the heavier cousins of known particles – may…

Logic violation…
Associate Professor Dr Joan Vaccaro, of Griffith's Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called 'T violation' could be the origin of time evolution and conservation laws. In her research published in The Royal Society Dr Vaccaro says T violation, or a violation of time…

Information. Decay. Entropy. Clues…
Information may seem ethereal, given how easily we forget phone numbers and birthdays. But scientists say it is physical, and if a new study is correct, that goes for quantum systems, too. Although pages of text or strings of bits seem easily erased with the press of a button, the act of destroying information has…

Accuracy: Does it even exist? Break the mirror.
Better thermometers might be possible as a result of a discovery, where physicists have found a way to calibrate temperature measurements by monitoring the tiny motions of a nanomechanical system that are governed by the often counterintuitive rules of quantum mechanics. (1) Accuracy: The measure of how correct you are based on what you have…
