Surprisingly, it can also become a superfluid even though each atom is a fermion! This is because of Cooper pair formation, just like in superconductors, but the transition happens at lower temperatures than superfluid helium-4, which is a boson.

aps.org/publications/apsnews/202110/history.cfm: October 1972: Publication of Discovery of Superfluid Helium-3 contains comments on the seminal paper and a graph which we must steal.

Good points:

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 pain point as of SVG 1.1...

Examples at svg/background.html which answers from stackoverflow.com/questions/11293026/default-background-color-of-svg-root-element/11293812:

This pain reflects directly on Inkscape: set SVG background color in Inkscape.

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.

Forms a normal subgroup of the general linear group.

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

Bibliography:

Within the The Holy Trinity of popular Brazilian music, Chico tends to approach the more down to Earth and heavy topics.

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.

The main four instruments are undoubtedly:but there is also amazing content on others which must not be missed, including:
