Why water puts out fires, why gold never corrodes, and why two identical reactions can take three seconds or three hours. Five subjects built from a handful of ideas instead of two hundred rules.

You get the intuition first β what's actually happening β 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 β not someone who needs to be talked down to. No gatekeeping, no condescension.
Recommended order: Chemistry β Biochemistry β Organic β Physical β Inorganic. Or skip straight to whichever one's been bothering you.
PDFEvery reaction in the universe is atoms trying to settle their outer electrons. Bonds, moles, acids and equilibrium once that one idea is in place.
PDFThe chemistry your body runs on β why enzymes make a reaction a million times faster, and what actually happens to a meal after you swallow it.
PDFNot memorising 200 reactions. Carbon has four bonds and electrons move from rich to poor β every mechanism in the course follows from that.
PDFWhy some reactions release heat and some need it, why a reaction can be inevitable and still take a thousand years, and what entropy actually measures.
PDFThe periodic table read as a map instead of a wall chart. Why gold never corrodes, why sodium explodes in water, and what a catalyst really does.
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 $40β$120/hr and roughly 30β40 total hours to work through five subjects from scratch.
5 ebooks, delivered as PDF files the moment you pay β nothing is posted to you. 102 pages, with worked examples and answers in every one. One flat price, no subscription.
Get all 5 books β $47 π§ͺThe Biology Bundle, the Chemistry Bundle and several new ebooks just went live. Get an email when new ebooks launch β at the launch price, before it goes up β and tell me which subject should come next.
There’s a confirmation email on its way β click the link in it and you’re on the list. I read every suggestion, and if enough people ask for the same subject, it gets built next.
