.... Do ghosts even *have* bones?

Did a slopbot make that rainbow.

I think I got one of these from the Pearson textbook rep the other day.

Also I think a lot of office-workers don't realize that "recalling" an email does nothing if the recipient isn't using Outlook.

If you think cloudflares are damaging, just wait till we get hit with the next cloud mass ejection.

Wait. He was pals with Deepak Chopra AND Lawrence Krauss?! I thought those two were arch-Twitter-enemies?

You speak it with other people in Akkadimia, obviously! 😉

My dad has been calling it 'Home Despot' since I was a kid, simply because it's funny.

This is why potlucks are a thing!

Oh, your guests are flying to see you and can't bring food? I'm sure you'll be fine with covering the cost of their airfare and lodging in exchange.

... which quantize angular momentum in integer units of h-bar (the reduced Planck constant).

But the electron's intrinsic angular momentum is hbar/2. It cannot be expressed as a spatial wavefunction. It indeed is not a ball, and is not rotating.

To elaborate on this: any expression of rotational motion that involves spatial coordinates (like the azimuthal angle phi in spherical coordinates) must satisfy Schrodinger's equation. Solutions of Schrodinger's equation for spherically symmetric potentials always involve the spherical harmonics...

Oh, I see. Like the exp{i phi} in the Y_{11} spherical harmonic. Those are for *orbital* motion, in which something really is orbiting or rotating (example of the latter: rotational modes of a diatomic molecule).

But the meme is about the intrinsic spin of the electron, and the meme is correct.

What do you mean by spin wavefunction phase? [genuine question]

... predictability can kick us into emergency shutdown mode.

Oh yeah, the link: www.cell.com/trends/neuro...

It should be open-access.

... drives neuroplasticity, but also too much of it too often overclocks the brain and causes inflammation.

My theory is that one feature of autistic people is a lower threshold for L.C. activation -- it would explain why we notice smaller "deviations from prediction" and why big failures of...

I read a review article about the 'locus coeruleus' a few months back and have been thinking about it in this context ever since. It's a (distributed) part of the brain that fires in response to "global model failure" [big failure of prediction] and juices the brain with norepinephrine, which...

Make a cup of tea and get on with your marking. 🫂
