Time crystals. In a timeless world…
It may sound like science fiction, but it’s not: Scientists have created the first time crystal, using a chain of ions. Just as a standard crystal repeats in a regular spatial pattern, a time crystal repeats in time, returning to a similar configuration at regular intervals. (1) Crystals developing in time. Over and over again.…

Words. Making the world collapse…
Physicists have a habit of depicting their discipline as “beautiful” or “elegant”, where an outsider might be forgiven for seeing no more than an endless morass of equations. In an ideal world, those equations would be unnecessary; the ultimate goal of physics – and science generally – is to describe the world as simply as…

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…
