General Relativity and Cosmology Textbook Recommendations
Finding a good textbook to learn about Einstein's theory of general relativity as well as modern developments in cosmology is not always an easy task. This video goes through some of the resources I've personally found quite helpful as well as those commonly recommended by other more experienced practitioners of physics. I hope to have provided you with some good recommendations on any educational level (bachelor, master, and beyond) such that you could further supplement your learning.

BOOK REVIEW: Physics and Philosophy by Werner Heisenberg
zhlédnutí 877Před měsícem
Physics and Philosophy is a book that explores the history of quantum mechanics. Written by one of the pioneers of the subject, it offers a first-hand account into the many ideas brought upon by the theory as well as its philosophical implications. The book serves as an interesting supplementary material to anyone learning the actual physics content of quantum mechanics through some formal text...
The Sad Lack of Popularization in Condensed Matter Physics

Of the many fields out there to study physics, applied research and condensed matter physics are frequently some of the most under appreciated areas of the field.

Kaluza Klein Theory: Unifying Forces Through Extra Dimensions

    If one writes y=y(x), then not all curves drawn are admissible, as some do not represent functions. I would rather have written y(t) and x(t) so as to represent all possible functions, with t something like time. What do you think?

While I haven't read the book I think that at the time this book would have been a great way for non-physicists to try and understand QM, especially with the lack of equations!

      I have no doubt that it is very common in some countries. I think it is equally as common in the US as well as a lot of other places. But my focus is on the public domain. Because usually this is the first exposure a prospective student of the discipline is going to get. A lot of people go into uni thinking they might do high energy physics, astrophysics, or some other exotic areas of physics. I think the lack of awareness condensed matter has in the public domain is something that could be improved upon. Since it does have poor 'marketing' (for lack of a better word), and we can't deny this (except in areas like quantum computing, chip industry, or superconductors). I hope this clarified things.
