Each volume in this series is essentially a ‘best of’ compilation of physics footnotes (including several I haven’t yet published online). The books are delivered to you in PDF format, with each page formatted as an attractive poster. This means you can print the pages out and bind them into a physical book, or laminate them individually and decorate the wall with your favorites. In addition (from Volume 2 onwards, as I haven’t updated Volume 1 yet), when you’re reading a volume online as an ebook, you can click any poster to go to its corresponding web page, where I usually provide more information about the topic, often including a video or animated GIF.
UPDATE: I created this page when I was selling these eBooks. I now distribute them freely to physics teachers and enthusiasts through my mailing list, which you can sign up to below. The completed volumes are contained in the first email you receive upon signing up. I’ll email you subsequent volumes as I finish them.
I hope you enjoy them!
