Serious science and mathematics readings

[close] Please only propose books that you seriously intend to read, and are accessible from the local bookstore / Amazon / Kindle at a reasonable price. A great monograph worth 200 Euros in one's university library is not a practical suggestion for others.

Don't use this as a platform to flaunt your credentials for external validation. If someone comes across as ignorant on a certain topic, they are an opportunity to pass on the baton of knowledge, not a punching bag to feel great about one's intellectual superiority.
Conversely, don't be afraid to ask questions, but try to do some prior background research so that you can engage with others more fruitfully rather than making impulsive arguments.

The usual guidelines on non tolerance of discrimination on basis of race, gender, age etc. obviously apply.
