Woodworking Jig & Fixture Building
Build a jig that produces identical parts every time. The jig transfers skill from craftsman to tool. A skilled worker makes one perfect piece. A jig lets anyone make a thousand.
Metal Filing & Fitting -- Hand Precision
Before machine tools, precision came from hand filing. File metal flat, square, and to dimension using a file, a square, and a surface plate. Patient, precise, and deeply satisfying.
Complete Filing Set (Swiss, 12-Piece)
Twelve Swiss-pattern files: flat, half-round, round, square, triangular, and knife -- in bastard and smooth cuts. Plus a file card for cleaning. Fundamental metalworking tools. With files and patience, you can make anything.
Ethics of Invention -- Second-Order Effects
The cotton gin was supposed to reduce labor. Instead it made slavery more profitable. Every invention has consequences the inventor did not intend. This seminar explores who benefits, who suffers, and how to think about responsibility.
Quantum Mechanics for Non-Physicists
Two-hour session. Superposition, uncertainty, wave-particle duality, entanglement using analogies and demonstrations. Quantum mechanics is strange but the most precisely tested theory in science. Your phone uses it.
Double-Slit Experiment Kit (Laser & Detector)
Laser pointer, precision double slit, screen, and single-photon detector. Fire photons one at a time through two slits. They create an interference pattern as if each photon went through both slits. This will break your intuition. Good.
Philosophy of Science Seminar -- What Can We Know
Small group (max 5). The uncertainty principle is epistemology. What does it mean to measure? What does it mean to know? Bohr, Einstein, Bell -- the arguments are unresolved. The questions are eternal.
Advanced Physics Tutoring -- Quantum Theory
One-on-one. Schrodinger equation, matrix mechanics, perturbation theory, angular momentum. Prerequisite: calculus and linear algebra. Not easy. But beautiful.
Sterile Technique Workshop -- Infection Prevention
Hands-on aseptic technique: surgical scrub, gloving, draping, instrument sterilization, wound cleaning. Before carbolic acid, half of surgical patients died from infection. Surgeons operated in frock coats stiff with dried blood.
Surgical Instrument Set (Educational, Stainless)
Educational surgical instruments: scalpel handles, forceps, scissors, needle holders, retractors, hemostats. Stainless steel, autoclavable. For anatomy study and dissection practice.
History of Medicine -- From Barbarism to Antisepsis
Surgery before and after germ theory. Sawing limbs without anesthesia, 50 percent mortality. Then Pasteur, carbolic acid, sterile technique. A single idea -- germs cause infection -- saved more lives than any drug. Semmelweis figured it out before me and they drove him to madness.
Microscopy Workshop -- Seeing Germs
Hands-on microscopy. Prepare slides, stain bacteria, observe microorganisms that cause infection. My father improved the microscope lens. I used the improved microscope to see what was killing surgical patients. One generation builds the tool, the next uses it.
