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.

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.

A piece of wire exactly 11.8 inches long. The distance light travels in one billionth of a second. I hand these out at lectures. Hold it. Feel how short a nanosecond is. Now multiply by a billion. That's one second. Never waste a nanosecond.

Learn to play my sonatas. Moonlight, Pathetique, Appassionata, Waldstein, Hammerklavier. We start with the ones you can handle and work up to the ones that break you. The Hammerklavier has destroyed better pianists than you. That's what makes it worth trying.

Point chisel, tooth chisel, flat chisel, claw chisel, rasps, rifflers. The same tool types I used on the David. Carbide-tipped for modern marble. I'll show you how to find the figure hiding in the stone.

Quills, iron gall ink, parchment. The tools I used to write 14,233 lines by hand. I'll show you how to hold the quill and form the letters. Your handwriting will never be the same.

My improved astrolabe design. Measures the altitude of stars and planets, tells time, finds latitude. The GPS of antiquity. Brass construction, hand-engraved. I'll teach you to read the sky.

Walk-in pop-up greenhouse, 3m x 2m x 2m. Steel frame, UV-resistant cover, roll-up door, 4 ventilation windows. Sets up in 30 minutes, no tools needed. Great for extending the growing season.

Hands-on physics lessons using real machines. We'll build levers, compound pulleys, and test buoyancy in water. You'll understand why ships float, how cranes work, and how I held off the Roman navy with math and mirrors.

Working model of my water-lifting screw. Turns by hand, lifts water uphill. Still the best irrigation device for low-tech farming. I invented this 2,300 years ago and nobody's improved on it.
