Black Hole Mergers and Multi-Messenger Astronomy - Sixty Symbols
Sixty Symbols

The interferometer to (astro)physicist is just like the SDR to (ham)EE.

LIGO is so sensitive I bet it can even detect the Luminiferous Ether, and if I were to have my own LIGO, pretty obvious the Michelson-Morley would be the very first experiment I would do.

Why nobody is trying that any more? Disappointed.

Ray Holt and the history of MP944/Cadc @ Rome Technopole, 2017
Leo Sorge

Intel 4004 was not the first microprocessor.

The first microprocessor was Ray Holt's MP944, designed for the F-14 fighter jets and therefore kept secret.

Analog computers are making a comeback, by doing analog matrix multiplication needed in AI by repurposing flash memories cells to do analog multiplication instead of data storage (see from minute 15:50 for how it's done).

Not sure if this has been posted already...

Suppose you have a right-angled triangle with a shorter side of length 'a' and the hypotenuse has a length of zero, what is the length of the third side?

Hint: use your imagination.
