The general result from eigendecomposition of a matrix:becomes:where is an orthogonal matrix, and therefore has .
Appears to have just one, other bacteria can have more. TODO position in NCBI. Sequence determined in 1979: www.ncbi.nlm.nih.gov/pmc/articles/PMC382992
TODO why do we care about this?
Note that if a group is k-transitive, then it is also k-1-transitive.
Note that this is not the conventional starting point for gene numbering: Section "E. Coli genome starting point".
This classification is too restrictive, and too South-centered. But if is worth knowing.
E-learning websites must keep content free, only charge for certification Updated 2024-12-23 +Created 1970-01-01
Charging for certification is fine. Creating exams and preventing cheating has a cost.
Another thing that is fine charging for is dedicated 1-to-1 tutor time. This is something Udacity is doing as of 2022.
www.investopedia.com/articles/investing/042815/how-coursera-works-makes-money.asp has a good mention:and it links to: www.freecodecamp.org/news/massive-open-online-courses-started-out-completely-free-but-where-are-they-now-1dd1020f59/, very good article!
MOOCs were first created by people with utopian visions for the internet. This means the idea for platforms like Coursera was likely conceived without a business plan in mind. Nonetheless, Coursera has managed to monetize its platform. It is worth noting, however, that monetization has lead to the effective elimination of the original MOOC idea, which is predicated on ideals like free and open access, as well as the building of online communities.Coursera users must pay to engage with the material in a meaningful way and take courses for individualistic purposes. This has been a consistent trend among all major online education platforms.
That is a fundamental guiding principle of OurBigBook.com. The educational content must be licensed CC BY-SA!
Perhaps the most reliable way of reaching this state is E-learning websites must allow students to create learning content.

- www.classcentral.com/about amazing, they can make money just from ads! I wouldn't expect that they could scale like TripAdvisor, because travelling means very local knowledge, I would expect there to be much fewer MOOCs and for them to be more easily findable on Google. Good thing though, this website.
How are the bands measured experimentally?
Why are there gaps? Why aren't bands infinite? What determines the width of gaps?

Ah, this seems like a nice dude.
Fred Sanger 1918-2013 by Birgitta Olofsson (2013)
Source. This is a good video especially is you know Cambridge, to help situate Sanger's places a bit. Good Sanger quote at the end:I always tell people, it is much easier to get the second one than the first
A different and more elegant way to express Maxwell's equations by using the:instead of the:
Strangeness Minus Three (BBC Horizon 1964)
Source. Basically shows Richard Feynman 15 minutes on a blackboard explaining the experimental basis of the eightfold way really well, while at the same time hyperactively moving all over. The word symmetry gets tossed a few times.Crystallography determination with a transmission electron microscopy instead of the more classical X-ray crystallography.
is by far the most important of because it is quantum mechanics states live, because the total probability of being in any state has to be 1!
has some crucially important properties that other don't (TODO confirm and make those more precise):
- it is the only that is Hilbert space because it is the only one where an inner product compatible with the metric can be defined:
- Fourier basis is complete for , which is great for solving differential equation
Good animation explaining it: Video "Electron transport chain by HarvardX (2017)".
Startup lists:
Deep tech (have labs) unicorns:
- Oxford Nanopore Technologies
- Graphcore
- CMR Surgical
- Britishvolt
- Touchlight Genetics
Almost deep tech but possibly without labs:
- Exscientia
Not to be confused with algebra over a field, which is a particular algebraic structure studied within algebra.
