Subcase of a normed vector space, therefore also necessarily a vector space.

Appears to be a small section from the Diamond Sutra. TODO find or create a video of it, it is just too awesome.

This piece is a reference to Dragon boats from the Dragon Boat Festival.

The explosive moments presumably represent the intense rowing action of a dragon boat race competition.

TODO date composed.

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 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 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:

As of 2019, all known physics can be described by two theories:

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

Figure "xkcd 435: Fields arranged by purity" must again be cited.

One of the best ways to think about it is the transversal time dilation thought experiment.
