Ciro Santilli @cirosantilli 37

Once upon a time, when Ciro Santilli had a job, he had a programming problem.

A senior developer came over, and rather than trying to run and modify the code like an idiot, which is what Ciro Santilli usually does (see also experimentalism remarks at Section "Ciro Santilli's bad old event memory"), he just stared at the code for about 10 minutes.

We knew that the problem was likely in a particular function, but it was really hard to see why things were going wrong.

After the 10 minutes of examining every line in minute detail, he said:and truly, that was the cause.

And so, Ciro was enlightened.

Option 1) git commit. Doh!!!

Option 2) git rebase. Basically allows you to do arbitrary modifications to the tree. The most important ones are:

Why should I care when I can calculate new x and new time with Lorentz transformation?

Answer: it can give some qualitative intuition on what is larger/smaller happens before/after based only on arguably more intuitive geometric considerations, without requiring you to do any calculations, see e.g. Figure "Spacetime diagram illustrating how faster-than-light travel implies time travel".

Most of them use titles from TV Tropes.

Some people call it "operating System".

The main parts of those systems are:

In the Galilean transformation, there are two separate invariants that two inertial frame of reference always agree on between two separate events:

However, in special relativity, neither of those are invariant separately, since space and time are mixed up together.

Instead, there is a new unified invariant: the spacetime-interval, given by:

Note that this distance can be zero for two events separated.

How are the bands measured experimentally?

Why are there gaps? Why aren't bands infinite? What determines the width of gaps?

One can't help but wonder if he smokes pot or not.

Also one can't stop thinking abot Leonard Hofstadter from The Big Bang Theory upoen hearing his name.

No good per-sub way as of 2022:

He used to train the 800,000 imperial guard troops at the Capital, much like Lin Chong. He's not one of the 108 Stars of Destiny.

Chanbara (チャンバラ).

Those movies are "all the same". A quasi lone superhuman samurai with a good inside but painful problems helping out random people, mostly villagers in trouble and bitches in debt.
