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.

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.

The book I co-wrote with Brian Kernighan. 272 pages. Every C programmer alive has read it. Clear, concise, no padding. The entire language specification fits in your back pocket. Borrow it, read it, write hello world, return it.

Full bike tune-up: brakes, gears, chain, tires, cables, bearings. I work on road bikes, mountain bikes, city bikes, and e-bikes (non-motor parts). 10 years as a weekend mechanic. Drop off at my shed or I come to you (within Trapani). Most tune-ups done in 1-2 hours while you wait.

I'll teach you what I proved in my master's thesis: switches are logic. AND, OR, NOT. Wire them together and you can compute anything. We build circuits on a breadboard. By the end, you'll have a working binary adder made of transistors. From there, it's just scale.

I gave Europe the number zero. I wrote the book on algebra (al-jabr). I'll teach you both. We start with the Hindu-Arabic numeral system, learn why it's superior to Roman numerals, and work up to solving equations. The algorithm is just a recipe. Follow the steps.

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.

I'll teach you linear perspective, isometric projection, and how to draw machines that could actually be built. Bring a ruler, compass, and pencils. We draw by hand. No CAD. If you can't draw it, you don't understand it.

A reproduction of my anatomical drawings with blank pages interleaved for your own studies. I dissected 30 corpses to understand how the body works. You can study from the drawings instead. Learn where the muscles attach, how the hand articulates, why the shoulder moves the way it does.

Learn to decompose problems into repeatable steps. We start with simple sequences, add loops, add conditionals, and build up to something that could compute Bernoulli numbers -- the algorithm I wrote in 1843. Paper and pencil only. No computers. The machine is not the point. The pattern is the point.
