Lex Fridman interviews legendary chip architect Jim Keller about Moore's Law, microprocessor design, and first-principles thinking. Keller draws on his work at AMD, Apple, Tesla and Intel, discussing instruction sets, transistor budgets, and self-driving.

3Blue1Brown introduces Fourier series, from the heat equation to drawing arbitrary shapes with rotating circles. It builds a visual intuition for decomposing functions into sine waves.

Kirsten Dirksen visits retired mailman Russ Finch in Alliance, Nebraska, who grows oranges, figs and pomegranates in a backyard greenhouse without paying for heat. The greenhouse uses the stable temperature of the earth, with underground earth tubes, to heat and cool itself.

The first lecture of Stanford's Natural Language Processing with Deep Learning course, taught by Chris Manning and Richard Socher. It introduces NLP and word vectors, including SVD, skip-gram, CBOW, negative sampling and word2vec.

A two-minute video of Ira Glass on the creative process, describing the gap between taste and skill when starting out and urging you to keep producing until your work matches your taste.

Professor Ruzic explains modular micro-reactors: self-contained nuclear units with passive safety whose fuel lasts about 20 years. He covers their use for process and district heat and where they can compete with diesel generation.

A two-minute Rouxbe cooking-school demo of how to heat a pan properly before cooking. It uses the Leidenfrost effect, where water beads and skates across a hot pan, to show when a stainless steel pan is ready.

A 1979 BBC Nationwide report asking whether word processors and networked microprocessors could end office commuting. It shows early word processing and a woman working from home, with surprisingly prophetic predictions.

BigClive tears down a heated electric shower head of the type common in some countries, often called a suicide shower. He examines the construction and the dangerous fault conditions, such as poor insulation and missing earthing.

David Ditzel of Esperanto Technologies presents their massively parallel, energy-efficient RISC-V processors at the 7th RISC-V Workshop in 2017. It covers the high-performance many-core design aimed at machine learning.

Samuel Falvo II live-codes a text preprocessor and blog engine in Forth over about an hour. It shows Forth's dictionary being snapshotted and restored in place of mutation, and how a small Forth system gets real work done.
