what about "false" statements?

September 18, 2016

Author:       Miguel Delete  Reply  IP  
I've been browsing this web pages for a while; I find many appealing statements, about Physics, Math, teaching, etc. But, to my dismay, I read in the "about the Project" section the issue of "false statements". Several of the listed "falses" are simply still not decided themes, or imprecise statements. I find this goes against the intended objectives of the book

CS: The statements you point to are all settled by experiments - and known to be false. Falsehoods weaken people. Truth makes people stronger. If you prefer falsehood over truth, this book is not for you.

China‘s quantum satellite

August 20, 2016

Author:       Chris Delete  Reply  IP  
What are the theoretical foundations for China's recent quantum satellite?

CS: Anton Zeilinger from Vienna has performed many neat experiments. The idea of entanglement is known (see vol. IV) and the experiment is a pretty extension of many similar ones realized in the past.

Excellent physics textbooks !!

The reading of your textbook vol 5 was something that socked me with pleasure. Studying Astrophysics for the last seven years in distant learning astrophysical course i never saw such a textbook with so much clarity and scientifically complete as yours series. Please continue and you will be rewarded by any means for your tremendous task of making physics a real pleasure to learn.

CS: Thank you!

Merci et thank you

I read the first three volumes in français and then the last ones in english. It was fantastic. Now I look at nature in a different way. Trees, animals and people have become much more interesting! Since I read it, it is really great to watch the world around me. Thank you!

CS: Merci pour le message - parlez-en à vos amis!
