Welcome to the World of Physics
Here you'll find study notes from The Feynman Lectures on Physics, from the microscopic world of atoms to the macroscopic structure of the universe. Let us explore together the most fundamental laws and the most profound truths of nature.
π Table of Contents
Chapter 1: Atoms in Motion
Explore the nature of matter and understand the atomic hypothesis β the most important knowledge in science. Learn how atoms make up everything around us, from a drop of water to life itself.
Chapter 2: Basic Physics
Explore the fundamental concepts of physics: from pre-1920s classical physics, to the quantum revolution, to the frontiers of particle physics. Understand the four fundamental interactions of nature.
Chapter 3: Physics and Other Sciences
How does physics provide theory and methods for chemistry, biology, astronomy, geology, and psychology? Understand core interdisciplinary challenges like "turbulence."
Chapter 4: Conservation of Energy
The abstract yet powerful "bookkeeping" idea: energy can change form, but the total remains constant. Use energy methods to analyze inclined planes, levers, and static equilibrium; understand kinetic energy, potential energy, heat and elasticity, E=mcΒ², and available energy and entropy.
Chapter 5: Time and Distance
Defining time by periodic phenomena and distance by triangulation and physical methods; from atomic clocks to stellar parallax, from electron microscopes to nuclear radii, understanding measurement consistency and quantum/relativistic limits.
Chapter 6: Probability
Describing uncertainty with the language of probability: binomial distribution and random walks, normal distribution and diffusion, Maxwell speed distribution, and quantum uncertainty making "probability fundamental."
Chapter 7: The Theory of Gravitation
From Kepler to Newton and Einstein: universal gravitation, tides and planetary perturbations, Cavendish measuring G, relativistic corrections and the equivalence principle, unified explanation of gravitational phenomena from the Moon to galaxy clusters.
Chapter 8: Motion
The limiting definition of velocity, displacement integrals, acceleration and multi-dimensional components, projectiles.
Chapter 9: Newton's Laws of Dynamics
F=d(mv)/dt, component method, midpoint numerical method, orbits and N-body problems.
Chapter 10: Conservation of Momentum
The third law and conservation, deriving collisions from the relativity perspective, elastic/inelastic, relativistic/quantum corrections.

If, in some cataclysm, all of scientific knowledge were to be destroyed,
and only one sentence passed on to the next generation,
what would it be?
All things are made of atoms
