See the fourth dimension.
A course in geometry and spacetime that you can actually picture, with weekly live problem sessions.
How it works
Picture first
Every idea starts as a drawing you can turn in your head.
Live problems
Bring the question you're stuck on to Wednesday's session.
Notes that stay
Every lesson comes with a one-page summary to keep.
Why pictures?
Most physics is taught as symbols first. We start with the picture, because once you can see it, the maths has somewhere to live.
You don't need to remember school physics. You need curiosity and an hour a week.
