Opera Magistris Communityis creating a compendium Book on Maths and Physics
Select a membership level
The main reason of sponsoring this book is to help us pay professionals to review the book content (Opera Magistris) , to redraw all figures in high quality vector drawings (and give them after to all for free), to pay people for peer review of the maths stuff and also to give the whole book and it source code for free to everybody in the world and not only the 6,000 first pages (see the corresponding Github repository). Also writing, updating, reviewing and answering to the e-mails about this book takes actually 5 to 8 hours every day including week-ends since 16 years and it is now quite hard to do our daily job and the book at the same time.

If we hit 500$/month we give for free 5 new pages of detailed mathematical proofs in the PDF every month.
