A hot hot place.

users.ox.ac.uk/~corp0014/B6-lectures.html gives a syllabus:

Problem set dated 2015: users.ox.ac.uk/~corp0014/B6-materials/B6_Problems.pdf Marked by: A. Ardavan and T. Hesjedal. Some more stuff under: users.ox.ac.uk/~corp0014/B6-materials/

The book is the fully commercial The Oxford Solid State Basics.

Pseudo-fuck.

December 2023: found the keys for the Kryptonite Kryptolock and the Abus in the house, so now I've got backup!

2023 lost one of the two keys to Kryptonite Kryptolock and to the Abus padlock:

2018 Kryptonite Kryptolock. Looks like: www.kryptonitelock.com/en/products/product-information/current-key/002031.html Includes Transit Flexframe-U Bracket carrier

2017 Abus Sinus Plus 471/150 HB U-lock. Sample seller with image: www.lockshopdirect.co.uk/products/abus-sinus-plus-471-d-lock-230mm-shackle-62620/

2017 an Abus chain and padlock, can't see marking easily. Chain length: 82cm.

Solution $Z$ for given $X$ and $Y$ of:where $e$ is the exponential map.

If we consider just real number, $Z=X+Y$, but when X and Y are non-commutative, things are not so simple.

Furthermore, TODO confirm it is possible that a solution does not exist at all if $X$ and $Y$ aren't sufficiently small.

This formula is likely the basis for the Lie group-Lie algebra correspondence. With it, we express the actual group operation in terms of the Lie algebra operations.

Notably, remember that a algebra over a field is just a vector space with one extra product operation defined.

Vector spaces are simple because all vector spaces of the same dimension on a given field are isomorphic, so besides the dimension, once we define a Lie bracket, we also define the corresponding Lie group.

Since a group is basically defined by what the group operation does to two arbitrary elements, once we have that defined via the Baker-Campbell-Hausdorff formula, we are basically done defining the group in terms of the algebra.

Bare metal programming is to run a program without an operating system below it.

Or in other words, it is basically implementing an operating system/firmware yourself ad hoc, together with your actual program.

"Barys" means "heavy" in Greek, because protons and neutrons was what made most of the mass of known ordinary matter, as opposed notably to electrons.

Baryons can be contrasted with:

As of 2020, account for about 20% of the known mammal species!!! www.sciencefocus.com/nature/why-are-there-so-many-species-of-bat/ mentions some reasons:

When you do get face to face time with students, don't teach a large group.

Everything you want to teach is already online.

And if it is not, then you are wasting your time saying it face-to-face instead of creating such online resource.

The only goal of meeting students is talking to them individually or in small groups to:

and letting them do the same amongst themselves.

If you talk to a large group, you will only reach / understand a very small percentage of the group, so your time is wasted.

It is better to deeply understand what 25% of the students feel and adapt the course material, than to talk to everyone at once, and have only 5% understand anything.

Very unfortunate license "public domain license" with a "non religious" clause, whatever the fuck that is, which completely defeats the point of a public domain declaration:

There's nothing like seeing the hypocrisy of the "Liberté, Égalité, Fraternité" people destroyed.

Interesting how Algeria now supports China's Xinjiang policy in 2019. But of course, dictatorships tend to work together

Ciro Santilli's father, an avid history reader, and in particular interested in the military dictatorship in Brazil through which he lived, once told Ciro how the French torture doctrine was directly adopted by Brazillian military, e.g. then even invited general Paul Aussaresses who had served in Algeria, to help them out with intelligence operations and give courses. Bro, fuck that.

But of course, the Americans weren't too far behind in Guantanamo.
