Ciro Santilli's general feeling is that university should not own IP, it should belong to the researchers. Instead, university should help researchers make their startups, so they can become big, and then we can tax them and reinvest in the universities.
Of course, this goes through the nonprofit impact measurement difficulty. Maybe we could instead limit the IP to some reasonably small percentage, like 10%?
But still, as of 2020, if feels like universities are way too greedy.
University entry exam by Ciro Santilli 40 Updated 2025-07-16
These are the most evil examinations society has.
They mean that until you are 18, you have to study a bunch of generic crap you hate just to get into university. Rather than studying whatever it is that you truly love to become a God at it as fast as possible and have any chance of advancing the field.
And then, if you decide that you want to change, which is not unlikely since you haven't really try to study what you signed up for before then, it can be very hard and time consuming, leading to a bunch of adults with useless degress they will never use at work.
With the invention of the Internet, all teaching material can be free and open source. Only laboratory space has any cost (besides the opportunity cost of participation in actual projects in a research team).

Tree traversal by Ciro Santilli 40 Updated 2025-07-16
In principle one could talk about tree traversal of unordered trees as a number of possible traversals without a fixed order. But we won't consider that under this section, only deterministic ordered tree traversals.

Testing and Circuit for a Condenser microphone by RSD Academy (2018)
Source.
Not very numerical, but shows a simple working breadboard circuit and an oscilloscope. He whistles with his mouth to get a pretty pure frequency.
That type of microphone requires a bias voltage. The circuit is in Ciro's ASCII art circuit diagram notation:
DC_9---R_10k--+--MICROPHONE--+--G
              |              |
              +-------V------+

Soundwaves on an oscilloscope by Animated Science (2015)
Source. Dude speaking to microphone. Some analysis of how different sounds look like. No circuit diagram.
There's a billion simple looking expressions which are not known to be transcendental numbers or not. It's cute simple to state but hard to prove at its best.
Open as of 2020:
