Unfortunately, it would not work for LLNL guys in the original paper - as they used a [monochromatic] laser already….

No I was referring to the load to burn off the excess energy.

Ramanujan's formula for Pi, I also have no idea how it works...

Ramanujan's formula for Pi, I also have no idea how it works...

Same idea as Fourier transformation we all like so much here on ASR? (Taylor series?)

Oh no, not wires again...

Scientists Have Created The Thinnest Possible Electrical Wire, Measuring Just 3 Atoms Wide

Scientists have developed the thinnest possible electrical wires, using tiny bits of diamonds called diamondoids to construct a wire just three atoms wide.

Physicists Discover a Remarkable New Type of Sound Wave

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered scientist

"A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered scientists’ previous beliefs about the sound wave, opening an avenue to the development of novel applications in acoustic communications, acoustic sensing, and imaging."

I thought it was one of these three shapes depending upon the cosmological constant's actual value. With most leaning toward it being flat.

That is just boring-old 3D stuff
Some newer and much fancier theories:

• Holographic Principle: the 'reality' is 2D flat, everything 3D is just a projection/illusion.
• One Electron Universe: the Highlander electron.
• M-Theory Strings: the other extreme with 10(+1)D. Or even more extra dimensions.

And I am a bit disappointed with the sellers of 'innovative' audio devices, they are so stuck with the 100 years old quantum 'technology'.
The shakti holographic stickers should be much more lucrative than those boring 3D stones. And the one-electron fuse would be 'awesome'. Or the M-String power cables...

Doctors in China have removed 420 kidney stones from a single patient, it's reported.

In 2009, a doctor in India removed 172,155 stones from a patient's left kidney during a three-hour surgery, according to Guiness World Records.

China: Doctors remove 420 kidney stones from patient

Doctors blame the Chinese man's love of calcium-rich tofu.

Current model of the cosmos assumes it is flat. Yet it could be round. If it is round, it means if you keep looking back farther and farther, you eventually arrive at where you are! Naturally this screws up many assumptions we make about the nature of universe.

My friend came from central Texas where he said it was so flat " that on a clear day you could see the back of your head" so maybe he was on to something

Would pi behave the same way if a different number base system, other than decimal, were used?

 

[egellings]

Bizarre little number.

I remember an article from the 80s written by Steve Wozniak where he used 6502 assembly language to compute pi to an arbitrary number of digits, depending on how long you let it run. It was pretty impressive coding. Must have been a slow weekend...

Yes. No. Yes. No.

In Base Pi, one Pi = 1.

Bizarre little number.

Indeed... as is the fine-structure constant 1/137 that shows up all over the place in quantum physics;
