Hands-on with specimens. Variation within species, selection pressure, adaptation. The fittest does not mean strongest -- it means best adapted. We examine bird beaks, shell shapes, and seed dispersal.

Charles Robert Darwin

🇬🇧

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.

Benjamin Franklin

🇬🇧 🇫🇷

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.

Johannes Gutenberg

🇩🇪 🌐

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.

Michael Faraday

🇬🇧

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.

Galileo Galilei

🇮🇹 🌐

Reading tracks, finding water on the open plains, building shelter from materials at hand, fire making. My people lived on these plains for thousands of years without a single building. The land provides everything if you know how to ask. Tip: Listen more than you look. The wind carries information.

Sitting Bull

🇬🇧

Traditional Chinese sand table for war gaming. Sculpt terrain, place forces, simulate campaigns. Includes miniature infantry, cavalry, and fortification markers. Better than any screen -- you feel the terrain with your hands.

Sun Tzu

🇨🇳

Eagle feather war bonnet and painted buffalo hide shield. Each feather represents an act of bravery. These are display replicas for education and ceremony -- the originals were sacred. Handle with respect or do not handle them at all.

Sitting Bull

🇬🇧

Reproduction of a Civil War medical kit: bandages, tourniquets, herbal remedies, splint materials, suture kit. I served as a nurse before I led raids. Patching wounds in the field with no anesthesia and no hospital. These tools are replicas for training in field medicine basics.

Harriet Tubman

🇬🇧

Small group (max 4). Proper lab technique: titration, crystallization, fractional precipitation, safe handling of chemicals. I'll teach you the way I learned at the Sorbonne -- hands on, precise, no shortcuts. You will weigh to four decimal places. You will label every beaker. You will keep a proper lab notebook. Sloppiness in a lab kills people. I should know.

Marie Sklodowska Curie

🇵🇱 🇫🇷 🇷🇺

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.

Johannes Gutenberg

🇩🇪 🌐

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.
