When I first read it my first thought was "So are quantum computers being used to simulate quantum systems yet?" .. what's the answer?

Not a linguist, but amongst others, Italian/French/Spanish/Portuguese are not millenia-old. I heard some "slangs" have the characteristics of outbranching languages. Globalization seems a strong uniformizer, but there may be other phenomena at play too?

Looking for advice or strategy ideas for an early career researcher on how to keep competitive while changing fields!
It's risky to go "all in" in a new direction and leave the comfort zone behind, whereas keeping your feet in two areas could make you uncompetitive in both..

Krebs cycle part 2: malic acid crystals. This compound is also responsible for apples being sour (malic comes from the Latin for apple) #sciart pic.twitter.com/iloSmpxxZM

Their choreography looks so cool. I think the individual rules are:
"try to go down to eat without pushing, while staying on frontline and close to neighbors, and when the group almost passes you, get back up"
This makes this awesome ghostly shape... twitter.com/Jamesdonovan45…

"irrationals are those numbers which are not the average of 2 rationals" sounds better to me

Take a 600-cell in 4D with 120 vertices ±v_i, i=1…60
Define F(x)=𝚷_i v_i·x
Stereographically project F from a 4-sphere to 3D, then Fourier-transform from momentum space to position space.
Result: this hydrogen wave function, with energy level n=61.

Usually I hate riddles like this that work only in the decimal system.
This one is not perfect but much better, because it also works in basis 6,8,.. (any even number >4, while bases 2, 4 are also morally ok for me even though you have to change a bit the statement). twitter.com/brilliantorg/s…

not sure it can give an actual drill:
1) Movement of "drill tip" by rotation + translations hard to implement from motor
2) No cancellation for moments of reaction forces may make drill handle unstable & hard to keep steady (either before, or during, contact w/ drilled surface)

that's awesome, and fascinating at the same time! is the model 3d, or for now only 2d?
