Nespresso Citiz (Backup Machine)
My backup Nespresso Citiz. For when the Linea Mini is rented out or when I can't be bothered to grind beans. Makes a decent espresso in 25 seconds. Pod machine -- not for purists, but perfect for mortals. Comes with a starter pack of 50 capsules.
Science for Young People -- The Christmas Lecture
A demonstration-rich science talk designed for children and teenagers. I started the Christmas Lectures at the Royal Institution in 1825. Fire, ice, magnets, sparks, bubbles -- real science made visceral. No equations. Just wonder. The Chemical History of a Candle -- six lectures explaining all of chemistry through a single burning candle.
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.
Self-Education Mentoring -- The Bookbinder Path
One-on-one mentoring for anyone without a formal science education who wants to learn. I had no degree, no university, no connections. I had a library and a willingness to work harder than anyone in the room. I will help you build a self-study plan and find your Humphry Davy -- the person who opens the first door.
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.
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.
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.
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.
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.
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.
