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.
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.
Writing & Persuasion Workshop -- Poor Richard's Method
Small group (max 6). I'll teach you how to write clearly, persuade effectively, and publish for maximum impact. I wrote Poor Richard's Almanack for 25 years. Sold 10,000 copies a year. 'Early to bed and early to rise' -- that's mine. 'A penny saved is a penny earned' -- also mine. Short, memorable, useful. That's the formula.
Physics Problem-Solving Tutoring
One-on-one tutoring in physics. Any level, any topic. I spent 10 years as a professor. The secret to teaching physics is this: never start with the formula. Start with the question. Why does this happen? What would you expect? Now let's check. The formula is just the shorthand for the understanding.
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.
Glass Armonica (Working Replica, 37 Bowls)
My most beautiful invention. 37 glass bowls mounted on a spindle, turned by a foot pedal, played with wet fingers. Mozart and Beethoven both composed for it. The sound is unearthly -- people fainted at performances. Some thought it caused madness. It doesn't. It causes wonder. Handle with extreme care.
Ink Making Workshop -- Oil-Based, From Scratch
Make your own oil-based printing ink from linseed oil, soot, and pigments. Water-based ink was fine for stamps but terrible for type -- it beaded up on metal. I had to invent a new ink. You'll leave with a jar of ink good enough to print with. Wear old clothes.
Bifocal Lens Demonstration & Fitting
I got tired of switching between two pairs of glasses -- one for reading, one for distance. So I cut the lenses in half and combined them. Revolutionary? No. Practical? Enormously. This workshop covers basic optics, lens grinding principles, and why bifocals work. Tip: The best inventions solve annoyances, not emergencies.
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.
Scientific Method Workshop -- Question Everything
Small group (max 6). Hands-on experiments: pendulums, inclined planes, falling objects. We'll replicate my actual experiments from the 1600s. You'll learn to form hypotheses, design experiments, collect data, and draw conclusions. Aristotle said heavy objects fall faster than light ones. I proved him wrong. You'll prove him wrong too, with your own hands.
Letterpress Printing Workshop -- Set Type, Pull Prints
Hands-on letterpress session. Pick individual lead type from the case, compose a line, lock it in the chase, ink the form, and pull a print. You'll leave with a hand-printed broadside. Tip: Set type mirror-image, left to right becomes right to left. The first time everyone gets it backwards. That's why we call it 'mind your p's and q's' -- they're mirror images in the type case.
Franklin Stove (Cast Iron, Working Replica)
Cast iron replica of the Pennsylvania Fireplace. More efficient than an open fireplace -- the baffle system circulates warm air into the room instead of up the chimney. I refused to patent it. Some things should be free. The Governor of Pennsylvania offered me a patent; I said no. Heat is a public good.
