These can be used to break cells apart from tissue, and also break up larger DNA or RNA molecules into smallers ones, suitable for sequencing.
This is a good and simple first example of Lie algebra to look into.
Notably, given the domain name, it is clear that he likes formalization of mathematics-stuff, like Ciro Santilli.
At first glance, looks a bit dry though, not many examples.

Nothing personal, just Ciro Santilli strongly disagrees with the moderation philosophies of these users.
One particular type of user Ciro particularly dislikes are those who do more moderation than content. Ciro finds it very hard to understand why some people spend so much time moderating. Maybe that's how politicians exist, some people just like that kind of activity.
The moderators tend to have lower intermediate rep. They spend too much time moderating and too little time coding.

That answer was clearly a labour of love, on a subject that will never ever make anyone any money (markup style). Too much meta rep, too little programming rep.
Flagged as spam, there obviously is affiliation between the first link and the poster, which is not disclaimed.

Filter graphs are a thing of great beauty. What an amazingly obscure domain-specific language, but which can produce striking results with very little!!!
A quick example from stackoverflow.com/questions/59551013/how-to-generate-stereo-sine-wave-using-ffmpeg-with-different-frequencies-for-eac/77730492#77730492 illustrates some of the fundamentals:
ffplay -autoexit -nodisp -f lavfi -i '
sine=frequency=500[a];
sine=frequency=1000[b];
[a][b]amerge, atrim=end=2
' +--------+
[sine=frequency=500]--->[a]-->| |
| amerge |-->[atrim]-->[output]
[sine=frequency=1000]-->[b]-->| |
+--------+So we see the following syntax patterns:
sine,amergeandatrimare filterssine=frequency=500: the first=says "araguments follow"frequency=500sets thefrequencyargument of thesinefilter- for multiple arguments the syntax is to separate arguments with colons e.g.

Ciro Santilli tried to add this example to Wikipedia, but it was reverted, so here we are, see also: Section "Deletionism on Wikipedia".
This is a good first example of a field of a finite field of non-prime order, this one is a prime power order instead.
, so one way to represent the elements of the field will be the to use the 4 polynomials of degree 1 over GF(2):
- 0X + 0
- 0X + 1
- 1X + 0
- 1X + 1
Note that we refer in this definition to anther field, but that is fine, because we only refer to fields of prime order such as GF(2), because we are dealing with prime powers only. And we have already defined fields of prime order easily previously with modular arithmetic.
Over GF(2), there is only one irreducible polynomial of degree 2:
Addition is defined element-wise with modular arithmetic modulo 2 as defined over GF(2), e.g.:
Multiplication is done modulo , which ensures that the result is also of degree 1.
For example first we do a regular multiplication:
Without modulo, that would not be one of the elements of the field anymore due to the !
So we take the modulo, we note that:and by the definition of modulo:which is the final result of the multiplication.
TODO show how taking a reducible polynomial for modulo fails. Presumably it is for a similar reason to why things fail for the prime case.
There are unlisted articles, also show them or only show them.
