Yup, this one Focks you up.

Richard Feynman's mentor at Princeton University, and notable contributor to his development of quantum electrodynamics.

Worked with Niels Bohr at one point.

Web of Stories interview (1996): www.youtube.com/playlist?list=PLVV0r6CmEsFzVlqiUh95Q881umWUPjQbB. He's a bit slow, you wonder if he's going to continute or not! One wonders if it is because of age, or he's always been like that.

This is the one Ciro Santilli envies the most, because he has such a great overlap with Ciro's interests, e.g.:

This is what happens when you apply a step voltage to a series RC circuit: TODO $I(t)$ graph.

In this chapter Richard Feynman talks about his experiences in Brazil.

"O Americano, Outra Vez!" means "The American, once again!" in Portuguese, which is what one of the samba school boss exclaimed when Feynman was not playing well his instrument, the frigideira, during a rehearsal.

Feynman really enjoyed Brazil's (and notably Rio's) stereotypical "take it easy and enjoy life" attitude.

This is a good read: quantumai.google/hardware/datasheet/weber.pdf May 14, 2021. Their topology is so weird, not just a rectangle, one wonders why! You get different error rates in different qubits, it's mad.

Bibliography:

Forms a normal subgroup of the general linear group.

Unsurprisingly the term "computer" became a synonym for this from the 1960s onwards!

This is basically what became the dominant formulation as of 2020 (and much earlier), and so we just call it the "mathematical formulation of quantum mechanics".

The IMDb of music! They actually have a reputation system apparently. And sneaked in a vinyl marketplace as well.

The website name sounds like play on words: disc + hog, with hog in the sense "memory-hog", i.e. something that consumes all your computer's memory.

Ah, Ciro Santilli loved this one... games young Ciro Santilli played.

And as a result, adult Ciro really enjoys tool-assisted speedruns of the game.

Intuition, please? Example? mathoverflow.net/questions/278641/intuition-for-symplectic-groups The key motivation seems to be related to Hamiltonian mechanics. The two arguments of the bilinear form correspond to each set of variables in Hamiltonian mechanics: the generalized positions and generalized momentums, which appear in the same number each.

Seems to be set of matrices that preserve a skew-symmetric bilinear form, which is comparable to the orthogonal group, which preserves a symmetric bilinear form. More precisely, the orthogonal group has:and its generalization the indefinite orthogonal group has:where S is symmetric. So for the symplectic group we have matrices Y such as:where A is antisymmetric. This is explained at: www.ucl.ac.uk/~ucahad0/7302_handout_13.pdf They also explain there that unlike as in the analogous orthogonal group, that definition ends up excluding determinant -1 automatically.

Therefore, just like the special orthogonal group, the symplectic group is also a subgroup of the special linear group.
