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.

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.

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.

Handmade tortoiseshell lyre with gut strings. The same instrument I used to accompany 27,803 lines of epic poetry. Tuned to the Dorian mode. I'll teach you the basic scales if you ask.
