The key and central motivation for studying Lie groups and their Lie algebras appears to be to characterize symmetry in Lagrangian mechanics through Noether's theorem, just start from there.

Notably local symmetries appear to map to forces, and local means "around the identity", notably: local symmetries of the Lagrangian imply conserved currents.

More precisely: local symmetries of the Lagrangian imply conserved currents.

TODO Ciro Santilli really wants to understand what all the fuss is about:

Oh, there is a low dimensional classification! Ciro is a sucker for classification theorems! en.wikipedia.org/wiki/Classification_of_low-dimensional_real_Lie_algebras

The fact that there are elements arbitrarily close to the identity, which is only possible due to the group being continuous, is the key factor that simplifies the treatment of Lie groups, and follows the philosophy of continuous problems are simpler than discrete ones.

A large part of these projects are on SourceForge as of 2020, it is scary. They just die.

Constructs the quaternions from complex numbers, octonions from quaternions, and keeps doubling like this indefinitely.

This is good, and very close competitor to OurBigBook.com.

But they killed local build, so they are going to die.

Ciro Santilli fantasizes that he is more compassionate than average.

He feels that this manifests itself notably through his desire/ability to create amazing documentation content and notably for free.

Also related is Ciro's worry about social inequality and how to reduce it.

In school, especially before university, Ciro felt that he always treated "the ugly/unpopular" (it is horrifying that such perception of a person exists! but true) girls really well, which led some of them to like him romantically. In part this was de to Ciro Santilli's self perceived compassionate personality and enter through the narrow gate approach to life. But was also partly Ciro's fault, he should have been clearer that he was not truly interested, but he was also lonely, curious about how it was like having girlfriend, and it feels good to have someone like you. This was a sin.

He also feels like he treated working class employees (and don't forget, this is Brazil, e.g. his building janitors in São Paulo lived in the nearby favela!) with extreme equality, sometimes even better, than other richer people.

One thing Ciro does not do however is give money to beggars on the street. Those beggars do make Ciro feel extremely bad for not giving, but he feels that they must be drug addicts to be out on the street like that, and that this money would be better invested in OurBigBook.com. But maybe this is just wrong. How fucked up the world is, how far away are we from unconditional basic income???

Once Ciro was hanging out with one of his father's on a group tourist, and she was a lesbian borderline/actually activist social reform person, and she promptly gave to a beggar without batting an eye, and that made a big impression on Ciro, making him feel even worse about himself.

It must be said that at times this compassion can be a weakness see Ciro's trip to the Municipal Market of São Paulo.

2019: broke with sign number 6. Ciro Santilli opened it up a bit destructively.

Board LED does not turn on (turned on on first plug, Ethernet always turns on):

Now just HDMI does not work. Possibly a monitor vs television problem:

Front camera video on Android 11: about 100MiB / minute. The encoding is however super inefficient, a FFmpeg re-encode without any options reduces it by 1/3.

For Fastboot mode: Power and Volume down simultaneously for 10-15s. It is OK if screen sleeps. On "no command", power then volume up to see options.

2023-10: touchscreen not registering touches anymore. Still displays images. Manage to regain access with wired USB mouse + a simple USB-C adapter. RIP. Will attempt replacement: store.ifixit.co.uk/products/google-pixel-3a-screen-genuine?variant=42388954448071, partly to get Authy access which I had never properly tested... Replaced screen, but at exact same status as before: shows image but no touch. thus I wasted my money and time (minus the learning) something else is broken.

Ciro once told a friend that his ideal life would be to "just chill out and eat his bread in peace" (while also learning and teaching the sciences). Quote "Omar Khayyam's chill out quote" comes to mind. See also: Ciro Santilli's cheapness.
