Physics (like all well done <science>) is the <art> of predicting the future by modelling the world with <mathematics>.

And predicting the future is the first step towards <control engineering>[controlling] it, i.e.: <engineering>.

<Ciro Santilli> doesn't know physics. He writes about it partly to start playing with some scientific content for: <OurBigBook.com>, partly because this stuff is just amazingly beautiful.

Ciro's main intellectual <physics> <fetishes> are to learn <quantum electrodynamics> (understanding the point of <Lie groups> being a subpart of that) and <condensed matter physics>.

Every science <reductionism>[is Physics in disguise], but the number of objects in the real world is so large that we can't solve the real equations in practice.

Luckily, due to <emergence>, we can use uglier higher level approximations of the world to solve many problems, with the complex limits of applicability of those approximations.

Therefore, such higher level approximations are highly specialized, and given different names such as:
* <chemistry>
* <biology>

As of 2019, all known physics can be described by two theories:
* the <Standard Model>
* <general relativity>

Unifying those two into the <theory of everything> one of the major goals of modern physics.
