the next question was — what makes planets go around the sun ? at the time of kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an orbit. as you will see, the answer is not very far from the truth. the only difference is that the angels sit in a different direction and their wings push inward.

I wish I had stumbled upon Feynman's lectures in high school. It's weird how things that used to be a disconnected mess are all now falling into place. And he sounds crazy. Hyperexcited, bouncing-off-the-walls kind of crazy. And I'm only reading him not watching the videos.
Also I now can't stop thinking about jiggling corks in the water.
if an apple is magnified to the size of the earth, then the atoms in the apple are approximately the size of the original apple
Hello! I was wondering what textbooks you would recommend for someone looking to get into mathematical proofs and introductory physics. I don't have physics in my courses this year so any notes would be helpful. Thanks!
Hello there!
I am glad you approached my ask box (or me).
Unfortunately I may not have the answers you might be searching, but I found Keith Devlin's book Introduction to Mathematical Thinking helpful as an intro. (It's neither a textbook nor is it exactly about mathematical proofs.)
Do my fellow math peers here know some good textbooks and want to share? Please feel free to reblog with some infos and references. (I would like to know some good books about mathematical proofs as well.)
As for physics I consider the Feynman lectures merely well-written.
[Caltech has uploaded the Feynman lectures as digital format/website:]
Another source I enjoy is Hyperphysics. [... although it is not a textbook either, but a good website]
It's a very neat and very basic html website with many good javascript boxes to directly play with some equations, as well as it contains well-summarized information and an overall good visualization and explanation of the concepts.
The mindmaps with topics (and sub-topics) are clickable:
Sub-topics are chunked into well-summarized: boxes:
And the plain/simple javascript forms are helpful for getting a quick intuitive feeling for the concepts when playing around:
(It helps me to make it compatible with my imagination. I don't know if other people might find this helpful as well.)
I consider this website merely neurodivergent-friendly, as it's well-summarized, well-structured, well-visualized, chunked, minimalist and quick-to-the-point, while also using very basic design, which makes it quick to load as well as more minimalist to look at - meaning less distraction and more focus for the depicted topics/concepts.
And you have an index window on the side which you can close:

Are we still doing “first of all” memes?
The feynman lectures are so casual. He uses the phrase “pip-pip-pip” to describe how an electron navigates a crystal lattice. I love it
Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far as we know it. In fact, everything we know is only some kind of approximation, because we know that we do not know all the laws as yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected.
