These have almost certainly been transferred to nuclear DNA in the course of evolution.
This isn't completely surprising, since when mitochondria die, their DNA is kind of left in the cell, so it is not hard to imagine how genes end up getting uptaken by the nucleus. This is suggested at Power, Sex, Suicide by Nick Lane (2006) page 196.
A limiting factor appears to be that you can't just past those genes in the nucleus, further mutations are necessary for mitochondrial protein import to work, apparenty some kind of tagging with extra amino acids.
However, you likely don't want to remove all genes from the mitochondria because mitochondria have DNA because they need to be controlled individually.
It has to swim fast, right!
So how is it that mitochondria are not inherited from the father?
Since that is a symmetric bilinear form, the associated matrix is a symmetric matrix.
By default, we will use the time negative representation unless stated otherwise:
but another equivalent one is to use a time positive representation:
The matrix is typically denoted by the Greek letter eta.
MakeCode Miro Bit by Ciro Santilli 40 Updated 2025-07-16
Microbit simulator using some Microsoft framework.
TODO the Python code from there does not seem to run on the microbit via uflash, because it is not MicroPython.
forum.makecode.com/t/help-understanding-local-build-options/6130 asks how to compile locally and suggests it is possible. Seems to require Yotta, so presumably compiles?
Presumably this is because Microsoft ported their MakeCode thing to the MicroBit, and the Micro Bit foundation accepted them.
E.g. there toggling a LED:
led.toggle(0, 0)
but the code that works locally is a completely differently named API set_pixel:
microbit.display.set_pixel(0, 0, )
Microsoft going all in on adopt extend extinguish from an early age!
Pion by Ciro Santilli 40 Updated 2025-07-16
Conceptually the simplest mesons. All of them have neutral color charge:
  • charged: down + anti-up or up + anti-down, therefore with net electrical charge electron charge
  • neutral: down + anti-down or up + anti-up, therefore with net electrical charge 0
Kaon by Ciro Santilli 40 Updated 2025-07-16
One strange quark bound with one up quark or a down quark. 6 combinations exist, 4 if we consider antiparticles the same as particles.
de Broglie relations by Ciro Santilli 40 Updated 2025-07-16
Relates particle momentum and its wavelength, or equivalently, energy and frequency.
The wavelength relation is:
but since:
the wavelength relation implies:
Particle wavelength can be for example measured very directly on a double-slit experiment.
So if we take for example electrons of different speeds, we should be able to see the diffraction pattern change accordingly.
MIT OpenCourseWare by Ciro Santilli 40 Updated 2025-07-16
CC BY-NC-SA unfortunately.
Upload is actually optional, and it appears that teachers do retain their copyright: ocw.mit.edu/ans7870/global/MIT_OpenCourseWare_FAQs.pdf Hmmm, so how have they convinced so many teachers to do it?
Made huge advances in radar.
Notably, Isidor Isaac Rabi was a leading figure there, and later he was head at the Columbia University laboratory that carried out the crucial Lamb-Retherford experiment and the anomalous magnetic dipole moment of the electron published at The Magnetic Moment of the Electron by Kusch and Foley (1948) using related techniques.

German graphite from The Genius Behind the Bomb (1992)
Source. Graphite was expensive because it had to be boron-free, since boron absorbs neutrons. But a boron process was the main way to make graphite. This type of pure graphite is known as nuclear graphite.
Plutonium-based.
Its plutonium was produced at Hanford site.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
