Astrophysics is not just pretty pictures. What happens when we go beyond awe and start asking why the universe must behave the way it does?

Astrophysics for the Rest of Us: Fundamentals invites you to explore the cosmos from first principles — not as a list of disconnected facts, but as a logical unfolding of what must happen when light, matter, and space play by the rules of physics.

We’ll begin with the most basic question — what does it mean to “see” something? — and walk step by step through how we gather information from the universe. From photons falling into telescopes to the fingerprints of atoms in starlight, you’ll learn how we extract meaning from distant messengers.

This course doesn’t assume you’re a physicist. What it assumes is that you’re curious, thoughtful, and willing to slow down and think things through. We emphasize conceptual understanding, plain language, and building your own reasoning from the ground up. You’ll walk in the shoes of astronomers, wrestle with cosmic puzzles, and come away with a deep, working intuition for how astrophysics actually works.

Whether you’re preparing for more advanced coursework, teaching others, or simply hungry to understand the universe for yourself — this is your starting point.

Note that this material is meant to be a required resource for a college course - no certificate is available directly from LeanPub.
