TODO understand.

The trivial takes a few hours.

The easy takes a week.

And what seemed hard takes a few hours.

As "deadlines" approach, feature sets get cut down, then there are delays, and finally a feasible feature set is delivered some time after the deadline.

The only deadlines that can be met are those of tasks which have already been done but not announced.

This is of course Hofstadter's law.

On the other hand, as a colleague of Ciro once mentioned, it is also known that the time it takes for a task to be done expands without limits to match the deadline. And therefore, without deadlines, tasks will take forever and never get done.

And so, in a moment, perceiving this paradox, Ciro was enlightened.

You can always learn pure theory later on for free or very cheap from books.

And above all, you can always learn software engineering later on for free, because the programming community is so much more open than any other so far, notably e.g. with Stack Overflow and GitHub, see also: Section "Ciro Santilli's Open Source Enlightenment". Ciro Santilli is trying to change that with OurBigBook.com, but don't hold your breath. But it is increasingly hard to understand why there isn't an university that forces teachers to publish all their notes and lecture videos (which should be mandatorily recorded) with a Creative Commons License, and then let anyone take whichever exams they want for a small fee or for free.

Actually, there is a good chance you will learn to program, like it or not, because chances are that you won't be able to find as decent a job doing anything else.

But there is one thing you cannot learn for free: laboratory work. Laboratory work is just too expensive to carry out outside of an institution.

Basically, if you don't do laboratory work in undergrad, you will very likely never be able to do so in your entire life.

Because laboratories are so rare and expensive, it is laboratories that put you in the best most unfair position at creating world changing deep tech startups, which is why when in doubt, choose the course that has the most experimental work. Yes, you won't be able to achieve those insanely concentrated equities of the early-Internet, as you will need more venture capital to run your company, but those days are over now, deal with it.

Debugging sucks. But there's also nothing quite that "oh fuck, that's why it doesn't work" moment, which happens after you have examined and placed everything that is relevant to the problem into your brain. You just can't see it coming. It just happens. You just learn what you generally have to look at so it happens faster.

法 (fa3) is the Chinese name for Dharma, and sometimes used as a way short way to refer to Buddhism.

Subgroup of the Poincaré group without translations. Therefore, in those, the spacetime origin is always fixed.

Or in other words, it is as if two observers had their space and time origins at the exact same place. However, their space axes may be rotated, and one may be at a relative speed to the other to create a Lorentz boost. Note however that if they are at relative speeds to one another, then their axes will immediately stop being at the same location in the next moment of time, so things are only valid infinitesimally in that case.

This group is made up of matrix multiplication alone, no need to add the offset vector: space rotations and Lorentz boost only spin around and bend things around the origin.

One definition: set of all 4x4 matrices that keep the Minkowski inner product, mentioned at Physics from Symmetry by Jakob Schwichtenberg (2015) page 63. This then implies:
