From why your coffee always goes cold to why extra dimensions are mathematically required. Five subjects, one approach, no fluff — each book starts with the idea and only then shows you the equation.
You get the intuition first — what's actually happening — and the formula shows up afterward, as the natural way to write it down.
Speedometers, MRI machines, GPS signals, blood pressure readings. If an example couldn't exist outside a textbook, it doesn't make the cut.
Written for someone smart who was taught badly — not someone who needs to be talked down to. No gatekeeping, no condescension.
Recommended order: Thermodynamics → Electromagnetism → Quantum Physics → Astrophysics → String Theory. Or skip straight to whichever one's been bothering you.
PDFEnergy, entropy and heat — from your coffee cooling down to the four laws that make every engine possible. Why nothing is ever truly 100% efficient.
PDFFields, flux, and the correction that let Maxwell predict light itself. Why electricity and magnetism turned out to be the same force.
PDFSuperposition, entanglement and tunnelling — the rules that take over once you're small enough. Why your SSD depends on physics that shouldn't be possible.
PDFHow astronomers measure a 93-billion-light-year universe without leaving Earth. Why looking into space means looking back in time.
PDFThe actual problem string theory was built to solve. Why extra dimensions are mathematically required, not just a fun idea.
Most people don't buy a book. They buy hours of someone else's time, one confused session at a time.
Based on 2026 average private tutoring rates of $40–$120/hr and roughly 30–40 total hours to work through five subjects from scratch.
5 ebooks, delivered as PDF files the moment you pay — nothing is posted to you. 139 pages, with worked examples and answers in every one. One flat price, no subscription.
