Modern Physics Preview
PHYS 101 · Module 6
This module gives a conceptual preview of twentieth- and twenty-first-century physics. Students encounter relativity, quantum ideas, gravity, cosmology, and the open questions that make physics an active field.
Lessons in this module
Special relativity in plain language
Special relativity describes motion near the speed of light and changes our ideas about space and time. This lesson explains its two main principles without advanced math.
Quantum ideas
Quantum physics describes matter and energy at very small scales. This lesson previews quantization, photons, wave-particle duality, probability, and uncertainty.
Gravity and cosmology overview
Gravity shapes planets, stars, galaxies, and the universe as a whole. This lesson previews general relativity, black holes, cosmic expansion, dark matter, and dark energy.
