First, two examples: 1.The Penrose's book "The road ro reality" may be, arguably, considered as a very fast and dirty introduction to modern physics as well as to some related relatively modern math topics. 2. I recently encountered a book Aleksandrov, Kolmogorov, Lavrentev "Mathematics: its...

Science Fictions have contributed much to entertainment and spreading awareness of issues related to complex scientific matters among the youth and the common man. It has also contributed to art etc. This has resulted in a spreading of scientific temperament and thereby has helped in adopting...

Hi, this is my introduction. I'm an italian physicist, ... a Prof. as italian students use to said. I'm an astrophysicist that is working on quantum-relativistic physics unification theories. I love any cultural challenges, especially in physics.

I'm beginning to study the Matt Roots book Introduction to Cosmology and in the section 1.3 Olbers' Paradox he writes: "If the surface area of an average star is A, then its brightness is B=L/A. The sun may be taken to be such an average star, mainly because we know it so well. The number of...

Is there a good introduction textbook or pdf for quantum chromodynamics?

Hi, I’m 28 years old and live in Minnesota. Most of my knowledge about physics is self-taught. (I love knowledge but don’t tend to thrive too well in academic settings for a number of reasons. Kind of like how some people are spiritual but don’t care for organized religion). Anyway, thanks Greg...

Hi I'm Robbie, a uni student studying physics and mathematics. I hate experiments and I like theory. Also, I'm not passionate about physics, yet. I really enjoy investigating math maybe because it has a much lower barrier for discovery (and breadth) in comparison to physics. Anyways, I hope I...
