And William's wife, Kate, has been diagnosed with cancer.

I'm really starting to feel sorry for the poor fellow.

Interesting chinese optical illusion

It's "divergence", not "diversion". And that only accounts for half the nature of light. The other half is: "The four-dimensional divergence of the dual of the previous tensor is the 4-current of electric charge". The second one accounts for the sources of light.

In other words,

\[ dF=0 \]

\[ d^{*}F=\mu_{0}j \]

(Not only light, I must say, but every other electromagnetic phenomenon, like the properties of capacitors).

Not very droll, I know...

Is the "frightened" dog part of the illusion?

It can't see the "hole" can it?(especially from its direction)

If you look at it turned upside down and screen placed horizontally, it looks like a raised pyramid, blocking the dog's way.

Had no idea

Two different dogs in that vid. Probably AI BS.

That meme mocks Prof. Kaku's controversial tendency to mix actual science with some dose of science fiction-inspired speculation 😆. Though i am sure you know that.

He occupies a strange space between a respected academic and a hype man for the universe.

Yes. I like how he would incorporate physics into his plays. The exploration of entropy in Arcadia, of course, and that scene's comic reference to a Newton's Cradle in RaGAD.

News story seen today:

Under a new law, California's 800,000 rideshare drivers have the right to unionize starting on Jan. 1.

Does that mean they will charge less?

I don't get it .Do they just pick up one ion per ride? (something like that?)

For want of a nail, the war was lost. For want of a hyphen, the joke was lost.

There is only you and AI** (and a few others here,no doubt) that get that.

Don't tell me.It may come eventually.

** quite prissy(no it didn't get it but it "had a go")

Edited by geordief

It relates a Ben Franklin attributed quote to the thud with which the unionize joke landed. Had I hyphenated unionize (after, in parentheses), the "charge less" double entendre would have been clearer.
