Pixelated Physics
Physics. Personified.
Pixel-art characters and designs, each built on one real piece of physics.
Tees, stickers, hoodies and mugs for science fans, students and the endlessly curious.
We exist because we think knowledge is for everyone.
The product is the character, not a quote on a shirt.

What Is Decoherence, and Does It Solve the Measurement Problem?
Decoherence is what happens when a quantum system becomes entangled with its surroundings: interference between its alternatives becomes practically invisible. It explains why everyday objects never show quantum interference, and it has been watched in the lab. What it does not do, on its own, is explain why a measurement has one definite result.
