| educational on their own.

| Thanks a lot man - I'm really happy to have this kind of
| feedback. The reason I wrote this is because I found most of
| the modern explanations lacking in intuition behind the
| equations - along with also not explaining what the actual
| equations meant. If you found this useful please share and
| subscribe - I'm also trying to provide intuitive guides to
| other concepts (Schrodinger's equation, Black Holes, Quantum
| Mechanics, other complex topics) and eventually I'm hoping to
| write books on some of these topics which present math and
| physics in a much more clear and intuitive manner. Math
| shouldn't be hard to grasp. At the very bottom level it's very
| simple but presenting it in a clear and intuitive manner I will
| admit is very hard. Also full credit to a lot of the material
| as well goes to Grant Sanderson (3Blue1Brown) and most of the
| diagrams there were generated using Vexlio which I also highly
| promote: https://vexlio.com/

| This is incredibly well explained. Everything is simple, yet it

| whole stuff is fascinating when explained in such a way that it
| makes sense. I fought with this during my 2nd year of engineering
| studies, but did certainly not understand half of it at the time.
| With that explanation, I would have enjoyed studying the subject
| so much more. I guess I was not smart enough to understand my
| textbook and all the consequences of the formulas, so that I was
| unable to be fascinated by the subject.
