The famous cat-in-a-box thought experiment by Austrian physicist Erwin Schrödinger is an illustration of one of the defining characteristics of quantum mechanics – the unpredictable behaviour of particles at the quantum level. It makes working with quantum systems incredibly difficult; but what if we could make quantum predictions? A team of physicists believes it’s possible.

Scientists in Germany have hit a new superconductivity milestone – achieving a resistance-free electrical current at the highest temperature yet: just 250 Kelvin, or -23 degrees Celsius (-9.4 degrees Fahrenheit). The work was led by Mikhail Eremets, a physicist at the Max Planck Institute for Chemistry, who set the previous high temperature record for superconductivity

For the first time, scientists have performed an iconic physics experiment with a positron – the antimatter counterpart of an electron, one of the fundamental particles. Not only did they get some truly interesting results, but this achievement could become the first step towards potentially revolutionary discoveries. The experiment – an antimatter version of the

Researchers at the California Institute of Technology (Caltech) say they’ve found a way to levitate and propel objects using only light – though, for the time being, the work remains theoretical. They hope the technique could be used for “trajectory control of ultra-light spacecraft and even laser-propelled light sails for space exploration,” according to a

Back in 2015, scientists found something amazing – a classic formula for pi hidden in the world of quantum physics. Pi is the ratio between a circle’s circumference and its diameter, and is incredibly important in pure mathematics. But this was the first time scientists had found it “lurking” in the world of physics, when

It’s been a year since the renowned and profoundly influential physicist Stephen Hawking passed away, and the Royal Mint has honoured his legacy in the form of a new commemorative 50 pence coin. If you’ve ever been concerned that British currency doesn’t feature enough astrophysical equations, we have good news. Although the collector’s item, sold on
