Position to position. 12 bits. Plus occasionally, an extra 12 bits for promotion. Promotion found by impossible position prefix. Whether it’s a capture, check, castle, what piece, etc. all interpreted by a reader program. What am I missing

The deBroglie wavelength of the photon IS its wavelength. That’s why it can’t squeeze into nm features and optical waveguides are still not used on-chip, after 35 years of effort.

Unless computation can be accomplished on differing overlapping frequencies, wdm devices, which resemble train switchyards, are huge, on the order of mm. So optical computing would have to take place at multi THz switching rates using very

Referring to computing, not data transmission. Perhaps some day, using quantum computing, all those differing ‘portly’ photons, superimposed, could yield advances in density. To mix different wavelength streams on chip involves wdm devices,

Are you sure? Are you expert enough to read those papers? How do you achieve large scale integration in waveguides transparent to available laser sources? How does 250nm compare to the integration in your cell phone’s cpu? And we are decade

Hundreds of of millions of dollars have been raised from naive investors by ignoring this fact. Often, board-member and founder physics PhD’s aid in the deception by omission.

All optical computing surfaces again! Warning. There is NO opportunity for large scale integration, the MOST IMPORTANT ASPECT in computing. This is because the de Broglie wavelength of the information carriers, typically 1.5um, is so HUGE.

“ Many people and businesses find it inconvenient when financial systems are down. It also seems unnecessary.” They make money on the float when money doesn’t move. They make money by efficient compression of business with fewer workdays.

Huh? Did you flunk freshman physics? E=K+U=GmM/2r−GmM/r=−GmME/r. We can see that the total energy is negative, with the same magnitude as the kinetic energy. For circular orbits, the magnitude of the kinetic energy is exactly

Between 9-5, you are right. Then, the action starts. (When I worked in Germany, they practically locked the doors at 5.)

Ok, big vacuum systems, (you need about 1E-4 torr for an e-beam) are not efficient for garbage treatment. Your comment is a good one; although I thought it was the low throughput that made e-beam photolithography impractical. Ok, so we don’

Electron beams are not cost efficient in photolithography. And it is proposed to use electron beams to treat water or garbage?

Photography has been very well developed technically for almost a century. Yet very little is considered art. The most interesting AI art, to me, are “image compilations” where the compiler appears to have taken just a bit of LSD.

Well, for now, anyway. I went to college in the 70’s. What strikes me is, once obviously wrong hallucinations are eliminated, LLM’s will do exactly what untalented liberal arts students did with their time, but with some useful stuff tacked

If you call an HVAC firm in Tucson, often they simply use the call to try to sell you a brand new unit, making disparaging comments about the condition of the current unit, and outright lying about its fixability.
