What do you want to learn?
Machine learning
From fitting a line to neural networks, convolutions, how LLMs write and how agents use tools and MCP. 28 hands on chapters.
Audio
Sound from air pressure to bits: frequency, harmonics, the spectrum, sampling, filters, EQ and compression.
Circuits
Build circuits and watch current flow. Ohm's law, series and parallel, capacitors, LEDs and fuses.
VR and XR
How headsets trick your eyes: stereo depth, lenses, tracking, latency, foveated rendering and comfort.
Design
UI styles from skeuomorphism to glass, plus white space, hierarchy, colour, type and the UX laws you can measure.
Physics
Motion, forces, energy, orbits, waves, light and gases as live simulations with graphs.
Biology
Cells, DNA, protein synthesis, genetics, the heart, neurons and homeostasis. Built for pre-med study.
Light
Light for artists and builders: light versus paint, warm and cool light, drawing shadows, light shows and projection mapping.
Anatomy
The whole body in 3D: skeleton and skull, circulation with blood flow, brain and nerves, pain pathways, organs and female and male anatomy.
CRNA
Anesthesia, cardiac and supporting drugs straight from their FDA labels, with flashcards, a mock quiz and airway anatomy in 3D. A study aid, not clinical guidance.
Muscles
63 muscles on a 3D body, with origin, insertion and action.
Elements
Atoms and the periodic table, with the math, electrons, Lewis dots and a mock exam.
