Electricity & Magnetism Workshop -- Fields You Cannot See
Hands-on session. Iron filings on paper over magnets -- watch the field lines appear. Compass needles deflected by current-carrying wires. Electromagnets lifting iron. I will explain how electricity and magnetism are two faces of the same force. James Clerk Maxwell later wrote the math. I gave him the experiments.
Lead Type Set (Textura Blackletter, Complete Alphabet)
Complete alphabet in Textura blackletter -- the typeface of the Gutenberg Bible. Upper and lower case, numbers, punctuation. Cast in traditional type metal (lead-tin-antimony). Each piece hand-finished. Handle with care; lead is toxic. Wash your hands after use. I didn't know that part.
Physics Tutoring -- Motion, Gravity & Forces
One-on-one tutoring in classical mechanics. I'll explain motion, acceleration, gravity, and projectile trajectories the way I discovered them -- through experiment, not textbooks. We'll use inclined planes, pendulums, and water clocks. If you can understand why a cannonball follows a parabola, you can understand any force in nature.
Relativity Explained -- Thought Experiments for Everyone
Two-hour session. No equations (well, one equation). I'll explain special and general relativity using the same thought experiments I used to discover them. Riding a beam of light. Trains and lightning strikes. Falling elevators. If you can imagine it, you can understand it. Tip: Relativity is not abstract. Your GPS uses it. Without relativistic corrections, your navigation would be off by 10 kilometers per day.
Impi Formation Drill -- Bull Horn Tactics
Group training (12-20 people). The bull horn formation: the chest pins the enemy, the left and right horns encircle. The loins wait in reserve facing away so they do not grow anxious. Commands by runner. We drill barefoot -- I threw away my warriors' sandals. Tip: A warrior who cannot run 50 miles cannot fight.
Mongol Composite Recurve Bow & Quiver (30 Arrows)
Laminated horn-sinew-wood composite bow, 160-pound draw. Effective range 350 yards. Comes with 30 arrows -- armor-piercing, broad-head, and whistling signal arrows. I will string it for you. Most people cannot.
Mounted Archery Training -- Shoot From the Saddle
Mongol children ride at three, shoot at five. Mounted archery at walk, trot, and canter. Composite recurve, thumb draw, the Parthian shot. Tip: Do not aim. Become the arrow. Your body knows the trajectory.
Desert Navigation & Survival -- Water, Sun, Sand
Finding water in the desert. Reading sun and stars. Building shelter from heat. My army marched from Egypt to Palestine through the Sinai -- if you cannot survive the desert, you cannot fight in it.
Full Plate & Mail Crusader Armor Set
Chain mail hauberk over padded gambeson, with plate reinforcement at shoulders and knees. Great helm with cross visor. About 55 pounds total. I wore heavier at Arsuf in desert heat. If you can fight in this, you can fight in anything.
Castle Design & Fortification Workshop
Concentric walls, flanking towers, murder holes, killing grounds. I designed Chateau Gaillard in Normandy -- three baileys, each commanding the one below. Philip took it by climbing through the latrine chute. Tip: Design for the attack you cannot imagine, not the one you expect.
Lens Grinding Kit (Optical, Beginner)
Everything you need to grind and polish your own optical lens. Glass blanks, grinding compounds, polishing pitch, a simple grinding jig. I ground my own lenses in Padua. It takes patience and steady hands. The reward is a lens that you made, that sees what no human eye can see alone.
Night Navigation Workshop -- Follow the North Star
Navigating by stars, moss, river direction, and landmarks in total darkness. I moved hundreds of people through swamps and forests at night with no map. The North Star was our compass. The drinking gourd song was our code. Tip: Move when the dogs cannot track -- in rain, through water, downwind. The night is your friend if you know her.
