Fermat and I invented probability theory by analyzing gambling. I'll teach you expected value, risk assessment, and Pascal's Wager. You'll leave understanding why the house always wins and why you should still play.

I co-invented game theory. I'll teach you the fundamentals: zero-sum games, Nash equilibrium, minimax strategy. We play actual games -- poker, chess, negotiation scenarios. By the end you'll understand why rational actors still make irrational decisions.

Packets, routing, TCP handshakes, DNS resolution. I designed TCP/IP and I'll explain it with diagrams and a glass of wine. You'll never look at a loading spinner the same way again.

My amateur red blend. It's not great. It's decent. The internet is better. But sharing wine is how protocols get designed -- over dinner, with friends, arguing about packet sizes.

I invented the web. I'll teach you to use it. We start with a plain HTML file, no frameworks, no build tools. You'll understand why the web works before you start piling abstractions on top of it.

I wrote Git in two weeks because I was angry. I'll teach it to you in two hours because you need it. Branching, merging, rebasing, conflict resolution. The fundamentals that 90% of developers still don't understand.

A dedicated chess machine inspired by Belle, the first computer to earn a master rating. Play against it. It will beat you. That's the point. Learn from losing.

I rode this through the halls of Bell Labs while juggling. Now you can ride it through your neighborhood. 20-inch wheel, good for beginners. Balance is information theory in action -- constant feedback, constant correction.

Handmade brass astrolabe with Arabic inscriptions. Navigate by the stars, find Mecca, tell time, predict sunrise and sunset. I mapped the known world. This device was my GPS. I'll teach you to read it.

6 practice locks from simple to complex. I was fascinated by locks -- the engineering is beautiful. Pin tumbler, wafer, disc detainer. Legal to own, useful to understand, excellent for developing mechanical intuition.

A box of precision brass gears, cams, shafts, and springs. The same components I designed for the Analytical Engine. Build a clock, a music box, or a mechanical calculator. Or redesign them three times and never finish. Either way, the gears are beautiful.
