Physics Course
With structure from Halliday–Resnick–Walker and mindset from Feynman, this course teaches physics for genuine understanding

Lesson 1: Physical Quantities
We ask a simple question: What does it mean to measure something?
This lesson introduces physical quantities as the starting point of all physical descriptions.

Lesson 1: Distance and Motion
Distance gives structure to motion.
In this lesson, we examine how motion is described using distance and time, and why measurement alone is not always enough to fully predict behavior.

Lesson 2: Chance and Random Motion
Many physical processes involve chance.
Here, we explore fluctuations and random motion as natural features of physical systems, using simple models to understand how order can emerge from randomness.

What You'll Learn
Develop Physical IntuitionWe break complex physical ideas into clear, manageable concepts so you can focus on understanding rather than memorization. Step by step, you’ll build intuition and confidence in thinking about physical phenomena.
Learn How Physicists ThinkThrough carefully chosen examples and guided reasoning, you’ll learn how physicists approach problems and construct explanations. This course emphasizes insight and flexibility, not rote formulas.
Use Physics as a Thinking ToolEach lesson equips you with conceptual tools you can apply immediately—to interpret motion, uncertainty, and physical systems around you. The goal is not just knowledge, but a way of thinking that carries forward.
