Finite general linear group Updated 2025-07-16
general linear group over a finite field of order . Remember that due to the classification of finite fields, there is one single field for each prime power .
Exactly as over the real numbers, you just put the finite field elements into a matrix, and then take the invertible ones.

Brazil Updated 2025-07-16
An awesome country, with amazing people and natural resources, and without an evil government like China.
When visiting Brazilian cities coming from Europe, one of the things that shocks the most is the amount of motorcycles. It seems that the poorer the country, the less people's lives are worth, and the more motorcycles there are.
Another thing that was shocking is the amount of phone spam when you get a new SIM card, some legal and some likely illegal. Everyone is desperate for cash it seems on a poor country, and everyone fights hard for it.
Quantum threshold theorem Updated 2025-07-16
This theorem roughly states that states that for every quantum algorithm, once we reach a certain level of physical error rate small enough (where small enough is algorithm dependant), then we can perfectly error correct.
This algorithm provides the conceptual division between noisy intermediate-scale quantum era and post-NISQ.
Buddhism Updated 2025-07-16
Ciro Santilli's favorite religion. He does not believe fully in it, nor has he studied it besides through brief Wikipedia and Googling.
Ciro likes Buddhism because it feels like the least "metaphysical explanations to things you can't see" of the religions he knows.
Rather, it feels more like "a plausible theory of the mind" and highly compatible with physics.
Ciro also believes that there is a positive correlation between being a software engineer and liking Buddhist-like things, see also: the correlation between software engineers and Buddhism.
