Why colliding blocks compute pi
A pair of idealized, frictionless blocks can be tuned—by choosing a mass ratio—to produce a collision count whose digits match those of π, even...
What IS Angular Momentum?
Angular momentum is the “oomph” that spinning and orbiting objects carry when their motion curves around a point, and it stays conserved even when...
What is Energy?
Energy feels like a substance—something you “have” or “lose”—but physics treats it differently: energy is a number, a bookkeeping quantity that links...
Noether's Theorem and The Symmetries of Reality
Conservation laws aren’t fundamental “rules” so much as bookkeeping devices that emerge from symmetry. Emmy Noether’s theorem links the two: every...
Space Time Livestream: Ask Matt Anything
A live Q&A with PBS Space Time turns physics questions into a tour of how “laws of nature” might be understood—through relativity, quantum...
Most Collisions Are Secretly in One Dimension
Collisions look chaotic, but for two objects the outcomes are largely locked in by conservation laws—because most collisions effectively behave like...
This New Idea Could Explain the Laws of Nature
A new theoretical framework argues that the universe’s fundamental “constants” may have drifted through random changes early on, and that only...
