Research & writing / How the world works

A complex world.
Worth understanding.

From sunlight to quantum fields. Lectures and essays on how matter works and how we know.

Sunlight and vitamin D: what I learned about summer in Moscow

How sunlight and vitamin D are connected, and why one recommendation cannot fit every person and season.

Atoms, quarks and fields. How we discover the structure of matter, and why a list of particles alone is not enough.

How fields describe particles and interactions, where mass comes from, and what the Standard Model still cannot explain.
