Since when did we start using v for frequency? v is velocity, f is frequency, lambda is wavelength. Using v for frequency is pure insanity. https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Physica l_Chemistry_(LibreTexts)/13%3A_Molecular_Spectroscopy/13.01%3A_The_Electromagnetic_Spectrum https://en.wikipedia.org/wiki/Frequency

The top chess programs now demolish the grandmasters. Scandals have developed, involving cheating, with players wearing hidden devices. Recently, the world champion lost a game, apparently agitated, as his opponent was wearing... send the children from the room... an ANALOG WATCH!!! Such barbarism has no place in our modern civilized world. Anyway, organizers now scan the player...

'So why haven’t we heard more about this if it makes solar panels generate electricity even after the sun sets? Well, that’s because it doesn’t generate tons of electricity. Instead, some estimate it only generates around 25 percent of the energy a solar panel can generate in a typical day. But that’s still clean energy that you didn’t have be

First time I have truely lost a personal computer (PC). Most likely cause of death: Too much CPU thermal paste interface material (Artic Silver 5) short circuiting the CPU pins damaging the processor. Second likely cause of death: CPU Overheat due to CPU Ventilator failure. Third likely cause of death: CPU metal pin contact oxidation. (It was a warm year) Fourth likely cause of death: ...

One story has been dominating the U.S. and international media cycle for the past 24 hours. It has been repeated by pro-Israel activists, Israeli government officials, reporters, and anchors throughout the U.S. media and even alluded to by the President. The thing is ? this story has not been confirmed in any way. It appears to come from a single source with a history of espousing calls for g...

I need to mount (many) RGB indicators at right angle to the PCB (i.e., so the light travels parallel to the plane of the PCB) The entire assembly needs to be *really* thin. Using SMT components, it seems like I'd have to use lightpipes to bend the light (typically emitted normal to the PCB). This will add to the thickness of the assembly (board thickness + component + pipe) A better...
