LORENZ gauge! LORENZ, not Lorentz!
Unbelievable. Now i see the world with different eyes.

What??Rive said:TIL that my keyboard actually has four extra buttons which I've never noticed before.
I just had to tear apart the thing for it's first ever thorough cleaning for this revelation...
My guess is: Annie Key, Lost Key, Stuck Key, and Boss Key.DaveC426913 said:What??Were they, like, molars waiting to erupt??
You have Wisdom Keys?
According to the no-hair theorem a black hole doesn't have a magnetic field. The paper says an Active Galactic Nucleus reversed its field. So I'd say that it's all the junk in the accretion "disk" that reversed.Oldman too said:TIL, A SMBH can reverse it's magnetic field.

Right. The accretion disk and the complicated mechanism that forms the jets of highly accelerated material that shoot out from either side, perpendicular to the disk.Hornbein said:According to the no-hair theorem a black hole doesn't have a magnetic field.

It's fine, there is the Lorentz-Lorenz equation!LCSphysicist said:LORENZ gauge! LORENZ, not Lorentz!

Is there a link to watch it on-line? (no TV here)BillTre said:TIL there will be a double Nova show (two hours!) on PBS today, on the recent (last few years) findings on the meteor impact that ended the Age of the Dinosaurs. David Attenborough is the narrator.
It has my interest.
I checked my keyboard after reading your post and there are three keys on there I have never used. No idea what they do, still don't but work got in the way so I didn't get round to checking.Rive said:Kind of
Somebody just made the power buttons look like LEDs.
And since I've never used them, they just lingered there, unnoticed![]()
Hi, sorry if the wording on my related post wasn't perfectly clear. It was made on my 42 wedding anniversary, about two margaritas into the celebration.Hornbein said:According to the no-hair theorem a black hole doesn't have a magnetic field. The paper says an Active Galactic Nucleus reversed its field. So I'd say that it's all the junk in the accretion "disk" that reversed.
And I'll make a guess why: Andreas Enge found the smallest prime number with 50001 digits, which is the largest number confirmed to be prime using elliptic curves: 1050,000 + 65,859.MevsEinstein said:Today I learned a bit about elliptic curves.

“The spatial distribution of the species has definitely increased by at least 30 to 50 percent in the last half a century,” said Ram Raghavan, an assistant professor in epidemiology and disease ecology at the University of Missouri, who has mapped the lone star tick’s spread. According to his research, the ticks are expected to continue to shift and expand their range; both to the north and west.
Alpha-gal syndrome is triggered by a complex sugar called galactose-alpha-1, 3-galactose, or alpha-gal, for short. The sugar is found in most mammals, but not in fish, reptiles, birds or humans. When the lone star tick feeds, alpha-gal is spread through its saliva, exposing the host’s immune system to the sugar. For some people, this triggers an overactive immune response the next time they encounter it.
That presumably works partly by creating a shady spot which fish are likely to move into and partly by making it easier for the bird to see the fish by reducing reflections of the sky.Ibix said:Today I learned that black herons do something called "canopy feeding" where they put their wings out in circles like umbrellas so that they don't look so bird-shaped to their prey looking up from the water.

This seems the most plausible.Jonathan Scott said:...making it easier for the bird to see the fish by reducing reflections of the sky.
This behavior defined its German name: "bell-heron".Ibix said:Today I learned that black herons do something called "canopy feeding" where they put their wings out in circles like umbrellas so that they don't look so bird-shaped to their prey looking up from the water.
