So why physics?
Physics is the natural science. It deals with the fundamental properties of matter and motion. Theoretical physics is concerned with the application of various mathematical models to the real world. Long story short, studying physics is a way of learning stuff about the world.
Everything is made of particles moving through space in time, right?
Only to some extent.
There is Special Relativity saying that motion is not what it seems to be intuitively, while time and space are unified into a single continuum which could be rotated such that space and time coordinates get mixed.
There is General Relativity which is based on the idea that space-time continuum is not an a-priori given fixed entity, but rather an ever-evolving network of causal relations. Surprisingly, this point of view automatically incorporates the gravitational interaction in the relativistic setting as a geometrical property of space-time itself.
There is Quantum Mechanics which completely changes our view of dynamical laws and the information available to the observer. It unifies the concepts of waves, fields and elementary particles.
Each of these theories passed excessive experimental testing. And there is a whole lot more. So no, it is not all about points moving in three-dimensional space according to the Newton's second law.
Pfff, should I be studying it, too?
It depends on your profession and interests. Like, for example, should I be studying nanotechnology? Not unless I plan on working in it. But I might want to self-educate just enough to familiarize myself with the general state of the art.
Trying to earn fame and make money, aren't we?
Hell no. I estimate the frequent visitors of this site to be somewhere from one to three, so I don't even bother indexing it with search engines. It was never meant to become popular and thus never shall it host any form of advertisement.
Who is this website made for then?
Primarily, for me. I've been feeling like I need a way of organizing my thoughts and technical calculations for a long time by now.
Then, for everybody whom it might help in any way. I've posted a collection of special literature on theoretical physics. Each of my personal notes, including all the calculations and the outlines of lectures which I have attended, is available in the lecture notes section. Also, I plan on adding links to the video recordings of lectures.
Finally, for those who wish to reach me, discuss with me anything personal or ask any questions related to the subject of theoretical physics. I am no professor nor am I working in science professionally yet, but being a first-year graduate (by spring of 2016), I might help a beginner student.
How is the content organized?
The content is organized by a collection of tags added to each of its pieces. Browsing a list of literature on one specific subject is just a matter of clicking on the corresponding tag label.
I have a question concerning one of your notes. How do I reach you?
Just leave a text comment under the note. The DISQUS commenting system is used throughout this site.
What technologies are made use of?
None, kind of (except for the web server, of course). The site is hosted as a collection of pre-compiled html files. This format is incredibly easy to deploy, impossible to hack and allows fine tuning. A bunch of open-source scripts and style sheets are used, as well as the harp static site generator.
What does the equation above mean?
