Modern Physics

Welcome to Modern Physics! This section ventures beyond the classical world to explore the revolutionary ideas of the 20th century, including relativity, quantum mechanics, and the strange behavior of matter at the atomic and subatomic scales.

Subatomic particle tracks in a cloud chamber showing the paths of ionizing radiation — Modern Physics challenges our intuition, revealing a universe where time is relative, particles act like waves, and energy comes in discrete packets.
