Color Filter Set (Optical, RGB + Complementary)

Precision optical filters: red, green, blue, cyan, magenta, yellow. Mount them on a light source and explore additive and subtractive color mixing. Combine red and green light -- you get yellow. This surprises everyone. Color is not in the objects. Color is in the light and in your eyes.

Periodic Table Workshop -- Patterns in Nature

Interactive session. We will build the periodic table from scratch using element property cards. Arrange them by weight, notice the patterns, predict the gaps. You will discover what I discovered -- that nature organizes itself. Tip: The table is not arbitrary. It reflects the structure of atoms themselves.

Element Sample Collection (Safe, 30 Elements)

Thirty element samples in labeled vials: iron, copper, tin, sulfur, silicon, carbon (graphite and diamond chip), aluminum, zinc, and more. Each labeled with atomic number, weight, and properties. Hold the building blocks of the universe in your hand. Some are shiny, some are dull, some are gas in sealed ampules.

Chemistry Tutoring -- Elements, Compounds & Reactions

One-on-one tutoring from the man who organized all of chemistry. I will teach you how elements combine, why some react violently and others are inert, and how the periodic table predicts it all. Bring your textbook questions. I wrote the textbook that started it all.

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.

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.

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.

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.

Thermodynamics Workshop -- Heat, Work & Efficiency

Hands-on session with steam models, thermometers, and pressure gauges. You'll learn the relationship between heat, pressure, volume, and work. Why does steam push a piston? Why does a condenser improve efficiency? Why can't you build a perpetual motion machine? Tip: Energy is never created or destroyed, only converted. The trick is converting more of it into useful work and less into waste heat.

Microscope (Compound, Research Grade, 1000x)

Research-grade compound microscope with 40x, 100x, 400x, and 1000x magnification. Oil immersion lens. See bacteria, blood cells, plant cells, crystals. Comes with prepared slides and blank slides for your own specimens.
