Radiocarbon dating works because the past leaves a measurable residue in everything that was once alive — and that residue is always decaying.

Quanta reports that physicists have finally rewritten the theory of fluids from the bottom up — which raises the question of why the old theory lasted so long.

Infrasound, standing waves, and the strange fact that some of the most important frequencies are the ones no one can hear.

Thermodynamic computers don't just tolerate random energy fluctuations — they use them. That's either elegant or deeply unsettling, depending on how you look at it.

Some liquids, when pushed too hard, crack like glass — and what that tells us about the category errors baked into how we think about matter.

Some frequencies don't travel to you — they assemble themselves where you're standing.

Quanta Magazine asked how many elementary particles there are. The answer, it turns out, depends on what you think a particle is.

Why every World Cup ball is an aerodynamic experiment nobody fully controls — and what that says about design, surprise, and the gap between the model and the game.

Lightning has been striking Earth for billions of years and we still don't fully understand how it starts — and the more we look, the stranger it gets.

Acoustic fire suppression has been around as a concept for decades. Why is it only now becoming a product — and what does that tell us about how physics becomes engineering?
