Theory that gases are made up of a bunch of small billiard balls that don't interact with each other.

This theory attempts to deduce/explain properties of matter such as the equation of state in terms of classical mechanics.

There's six to eight in different systems of the end of the 20th century:This mess is because people don't realize that clades are all that really matter.

The software engineer phrasing of simplicity is the ultimate sophistication.

Like all other principles, it is not absolute.

But it is something that you should always have on the back of your mind.

You aren't gonna need it is closely related, as generally the extra unnecessary complications are set in place to accommodate useless features that will never be needed.

Not to be confused with Subtitle Edit.

As of 0.54.0 this feels featureful, but extremely buggy or lacking UI obvious enhancements that would be simple to implement, and offer huge value:

It is hard to understand how that project reached this weird featureful but crappy state. Feels like they just gave push permission to a bunch of random people.

The dominating meme database as of 2020.

If you adda bit of impurities to certain materials, at low temperatures of a few Kelvin their resistivity actually starts increasing if you go below a certain critical temperature.

High school classical mechanics material, no mention of the key continuous symmetry part.

But does have a few classic pendulum/pulley/spring worked out examples that would be really wise to get under your belt first.

Revolutionary for its time, and a big part of Ciro's Enlightenment.

But too insane, and did not keep up with internet age, and so Ciro wants to kill it now.

A more specific type of E-learning website generally run by a specific organization.

A website, usually hosted by an university, that takes what is done in class, and pastes it online. It is already much more rational and efficient, and opens up the way for potential sharing outside of the institution (or by default paywalling as the University of Oxford did.

The fundametnal problem with VLEs is that they tend to not have enough incentives for students to contribute at all to the content. This is basically the major motivation behind OurBigBook.com.

"More complex and general" integral. Matches the Riemann integral for "simple functions", but also works for some "funkier" functions that Riemann does not work for.

Ciro Santilli sometimes wonders how much someone can gain from learning this besides the beauty of mathematics, since we can hand-wave a Lebesgue integral on almost anything that is of practical use. The beauty is good reason enough though.

Microscope by Antonie van Leeuwenhoek used to first observe microorganisms.

Their websites a bit shitty, clearly a non cohesive amalgamation of several different groups.

E.g. you have to create several separate accounts, and different regions have completely different accounts and websites.

The Europe replacement part website for example is clearly made by a third party called flex.com/ and has Flex written all over it, and the header of the home page has a slightly broken but very obviously broken CSS. And you can't create an account without a VAT number... and they confirmed by email that they don't sell to non-corporate entities without a VAT number. What a bullshit!

This is true. The level of competition in university entry exams in Asia in insane in the early 21st century compared to the West.

This is actually both good and bad. Good because it selects some very good exam passers. And bad because it selects some very good exam passers.

Initial issues off-the-bat:

We can almost reach the Lie algebra of any isometry group in a single go. For every $X$ in the Lie algebra we must have:because $e^{tX}$ has to be in the isometry group by definition as shown at Section "Lie algebra of a matrix Lie group".

Then:so we reach:With this relation, we can easily determine the Lie algebra of common isometries:
