This page collects the open errata and suggestions for the free physics volumes (and for the research texts) found at www.motionmountain.net Your feedback will be used to improve the book series for all readers.
Just email me for an invitation to edit at the address given on www.motionmountain.net/author.html . Then add your entry below. If you want, I will add your name in the acknowledgments. More help leads to more rewards.
2021: "When I press a green asterisk to go to a footnote, always appears the note beginning at the second line. The first one is hidden in the upper part."
Volume I: none.
Volume II: none.
Volume III: none.

MP: The chapter on entropy would gain in clarity if you showed how to reconcile the thermodynamic and statistical definitions of entropy. You could just direct the reader to a very good site from Khan university which shows the reconciliation in layman's terms. It is not done in the most professional (as in polished) manner but it is clear and it is the only one I could find.
Other improvements:
Check Hubble constant and other universe's parameters in the tables.
Decide whether to change to the 8x10 inch format also for the black and white edition. (Issues: corner films, new ISBN, no Lulu.)
Reduce pdf size by removing the photoshop/illustrator metadata. Either pre-process the ps files before distilling with awk/perl or use the commercial application 'pdf enhancer'. Saves 14.1MB (CS: I need a way to do this on the mac, offline, for all files in my image directory; just let me know how to do it, while keeping the original eps files editable with Illustrator.)
Convert all videos to one common codec. Use h.264 in case that by the time of the next book release Windows Media Player ships out of the box with this codec. Should save an additional 7MB & ensure future compatibility and playability across platforms - once all major platforms come with this codec. (The best way is with Avidemux. Download it from http://avidemux.berlios.de/download.html, drop your file in it, in the left column change video to MPEG-4 AVC (another name for H.264) audio to AAC and format to MP4, then save the new file.)
Add the story of Rudolf Mandl as told here (2020, ZS):

Volume VI, p. 47, after equation (54), the text says "The limit on the left is the upper limit for any engine or lamp, as deduced from relativity; not even the universe exceeds it. The limit on the right is the minimum power emitted by any system through quantum gravity effects." Shouldn't it be "The limit on the right... exceeds it. The limit on the left..."?
