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.
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.
Chemistry Lab Fundamentals -- Precision & Safety
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.
Astronomy Night -- Planets, Moons & Stars
Evening observation session (weather permitting). I'll show you Jupiter's moons, Saturn's rings, the craters of our Moon, and the phases of Venus. Bring warm clothes. Tip: Your eyes need 20 minutes to adapt to the dark. No phone screens. Learn the constellations first, then use the telescope. Context before magnification.
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.
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.
Radiation Science Workshop -- Safely Understanding Radioactivity
Two-hour session with safe demonstration materials. Cloud chambers to see particle tracks, Geiger counters to measure background radiation, mineral samples that glow under UV. You'll understand alpha, beta, and gamma radiation and why each behaves differently. Tip: Radioactivity is natural. You're surrounded by it. The banana you ate this morning was radioactive. Fear comes from ignorance. Understanding comes from measurement.
Geiger Counter (Professional Grade, Calibrated)
Professional-grade Geiger-Muller counter, recently calibrated. Detects alpha, beta, and gamma radiation. Includes headphones for the characteristic clicking sound. When Pierre and I first heard the clicks from our radium sample, we knew we had something the world had never seen.
Cloud Chamber (Wilson Type, Desktop)
Desktop cloud chamber that makes radioactive particle tracks visible. Pour in isopropyl alcohol, cool the base, and watch cosmic rays and natural radiation leave vapor trails in real time. It's like seeing the invisible forces that pass through your body every second. Mesmerizing and educational.
Telescope (Galilean Refractor, Brass, 20x)
Brass refractor telescope, 20x magnification -- same power as the one I used to discover Jupiter's moons. Two lenses in a tube. Simple, elegant, world-changing. Point it at Jupiter on a clear night. You'll see the four Galilean moons. Then you'll understand why the Church was afraid.
Electricity Demonstration -- Kite, Key & Leyden Jar
Safe indoor demonstration of static electricity, Leyden jars, and electrical conduction. We will NOT be flying kites in thunderstorms. I did that once and it was phenomenally reckless. Instead, we'll use friction machines and Leyden jars to generate sparks, charge objects, and understand positive vs negative charge. I named those, by the way.
Compass (Pocket, Brass -- Like the One That Started It All)
Brass pocket compass. When I was five years old, my father showed me a compass. The needle moved without being touched. Something invisible was acting on it. That moment -- the mystery of the invisible force -- started everything. Give this to a curious child and watch what happens.
