The butterfly effect is much stranger than most people think, and the famous line about a butterfly in Brazil isn't what Lorenz actually meant. A group of researchers has now worked out that quantum physics puts a hard wall on weather prediction, at 129 days. Not difficult after that. Impossible. And this has implications far beyond the weather forecast because chaos enters in everything from nuclear fusion to robotics to black hole physics. Let's take a look.

Artificial intelligence has eaten mathematics. In the past few months alone it turned up a counterexample to a conjecture open since 1939, disproved a thirty-year-old result, and made real progress on the Riemann hypothesis. Young mathematicians are somewhere between depression and anger about it. Physics is next, and almost nobody is talking about it. Let's take a look.

Quantum computing was supposed to be the next big thing, and for years the companies building it kept promising commercial payoffs were just around the corner and possible already with small, noisy devices (NISQs). Google, IBM, IonQ, they all gave dates. None of them delivered. So why is the industry more optimistic today than ever? Let's take a look.

A group of astronomers say they've spotted more than twenty giant unidentified objects racing around the Moon, some of them forty kilometres across, and that the Moon serves as a base for them. The daily mail loved it. My bullshit meter did not survive it. But underneath all this nonsense there's a serious question that almost nobody is looking into. Let's take a look.

You've probably heard that quantum mechanics is spooky, that measuring one particle instantly affects another across any distance. A physicist now says there's a reason: the universe doesn't have one dimension of time, but two. It sounds absurd, but he's got the maths and even a way to test it. Genius or nonsense? Let's take a look.

The origin of life is one of the biggest mysteries left in science. Now a group of researchers says there wasn't just one origin, there were two. And I want to explain why, despite how impossibly long ago it all happened, I'm actually optimistic that we'll one day work out how life began. Let's take a look.
