One of the first formal proof systems. This is actually understandable!

This is Ciro Santilli-2020 definition of the foundation of mathematics (and the only one he had any patience to study at all).

TODO what are its limitations? Why were other systems created?

We select for the general Equation "Schrodinger equation":giving the full explicit partial differential equation:

The corresponding time-independent Schrödinger equation for this equation is:

Good article about its history: en.bitcoin.it/wiki/BitcoinTalk

Founded by Satoshi Nakamoto, making it the earliest and one of the most important Bitcoin communities. TODO official in any way? Who founded it?

Instance of Simple Machines Forum, an open source, PHP-based forum system.

Some notable appearances:

On Ubuntu 20.10, just:

Note howver that .ass subtitle files can contain style information, which ffmpeg respects. Aegisub can produce and preview such styles, making .ass one of the best options.

Also sometimes called helium II, in contrast to helium I, which is the non-superfluid liquid helium phase.

He's good. Sometimes a bit repetitive, but generally pretty good.

Only the "original" videos matter. After those it became crap.

The book unfortunately does not cover the history of quantum mechanics very, the author specifically says that this will not be covered, the focus is more on particles/forces. But there are still some mentions.

We can reach it by taking the rotations in three directions, e.g. a rotation around the z axis:then we derive and evaluate at 0:$L_z$ therefore represents the infinitesimal rotation.

Note that the exponential map reverses this and gives a finite rotation around the Z axis back from the infinitesimal generator $L_z$:

Repeating the same process for the other directions gives:We have now found 3 linearly independent elements of the Lie algebra, and since $SO(3)$ has dimension 3, we are done.

Leads to the Dirac equation.
