Five books, one connected discipline — how machines, structures, circuits, reactions and flight actually work, instead of a pile of equations you memorised and forgot.
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: Mechanical → Electrical → Civil → Chemical → Aerospace. Or skip straight to whichever one's been bothering you.
PDFForce, load, stress, torque, friction and mechanisms — then one real timing-belt replacement that uses every idea in the book at once.
PDFA breaker kills the power to one room and nothing else in the house flickers. One dead bulb takes out a whole string of lights. Same electricity, opposite behaviour.
PDFA bridge holds for eighty years and nobody thinks about it until the day it does not. What keeps it standing is a small set of ideas, not luck.
PDFSomeone drew a box, then another box, then an arrow between them, and called it a process flow diagram. You copied it down and never found out what it meant.
PDFA plane weighing hundreds of thousands of pounds stays up for hours; a rocket weighing millions leaves the atmosphere entirely. Both beat gravity, using almost none of the same physics.
Most people don't buy a book. They buy hours of someone else's time, one confused session at a time.
