The Feynman Lectures are now freely available online

The Feynman Lectures is one of the most popular lecture series in physics. It’s a great resource for science enthusiasts, students, and teachers, and each lecture is just fantastic in general. Now, Caltech and The Feynman Lectures website have collaborated to put these lectures online completely free of cost.

The lectures themselves were first presented at Caltech in the 1960s by the legendary physicist Richard Feynman. The lectures have since been combined into a three-volume book. To date, about 1.5 million English copies have been sold, but now that it’s free, that number will probably stagnate.

We spoke with five people — a travel agent, a robotics expert, an engineer, a customer-service representative and a scriptwriter, of sorts — who have been put in this remarkable position. More than most, they understand the strengths (and weaknesses) of artificial intelligence and how the technology is changing the nature of work.

Worth a read.
