Feynman Hughes Lectures

1966 – 1971

These notes are for all those who want to learn more about science, math and nature as Feynman did; to learn more of how he taught and embrace his charge to pass on what we have learned.

I believe consistent with Feynman’s interest to teach as many as he could about science these notes are free and open to the public for non-commercial use.

The Hughes Lecture Notes, THL, website has been up for about 5 1/2 years. The visitor count has now exceeded 200,000 from over 185 countries around the world. Those visitors have “visited” and or downloaded over 1,000,000 lecture volumes .



This continual, and sustained, interest in Feynman’s approach to physics and related science fields is sufficient historical validation of the original transcription effort I undertook for my own learning experience. It also validates the process involved in scanning my notes to make the lectures available on line to the general public at no cost. Feynman would be pleased with this continual show of interest in his approach to teaching and exploring complex science subject matters.

For those interested in learning more about the creation of these lecture you will find them on a podcast:



HRL Podcast: An oral interview on the development and motivation for THLs

In March 2017,during a visit and tour at the now HRL Laboratories, LLC, I was interviewed about my interest in Feynman and how the notes came about. The HRL Laboratories have undertaken a project to capture and preserve its long history of scientific and engineering breakthroughs. The interview was conducted as part of capturing a part of the labs oral history. For those interested in that interview which has recently been made available as a podcast it can be found at http://www.hrl.com/podcast/2017/12/18/episode-002-john-neer
