Notes on Relativity

These aren't just notes, they're the collected musings of the great Roger Penrose, the man who dared to challenge time and space.

Date: 1965

"Time is what we want, and time is what we have. The only time we have is the time we give."

The Theory of Everything (Almost)

Or, as Roger liked to call it, "The Not-Theory of Everything (Mostly)"

Some highlights:

• The universe is a big mess.
• Time is relative, but only if you're a physicist.
• Gravity is like an invisible string that ties everything together (except on Tuesdays).

More on Relativity

• The grandfather paradox: A classic.
• The Singularity: A party waiting to happen
• The curvature of space-time: Because, you know, it's a thing

Other Notes

• Quantum Mechanics: Because, why not?
• Black Holes: Not as scary as they sound
