My suspicion is that most non-science people don’t realize that just coming up with a definition “this is a kilogram” and then being able to make a measurement in a lab where you can say with confidence “this is a kilogram” has involved an unimaginably huge amount of work and gazillions of dollars
Doing a 7-channel reciprocal frequency counter with external reference, for long term analysis of 10mhz oscillators. Input stages are hcu04 gates. #kicad#electronic#metrology
Janky shutter speed test setup. Made with stuff I had laying around. Photodiode is hooked up to the oscilloscope then I had the laser cat toy pointing at the photodiode. Trip the shutter and trigger on the rising edge and then just measure the pulse width.
Suppose that there was a #synth module(as in modular #synthesizers) which took a signal in, applied it to a quantum tunnel junction, then amplified the microwave noise from that junction, filtered it, integrated the noise power and turned that back into an audio sound.
Because of the structure of quantum noise, the response would all be at double the frequency as the incoming signal, but with a different shape because the quantum nature of the noise. The shape of the response sound would have information in it both about the temperature of the electrons tunneling through the barrier and about the photon energy relative to that temperature.
If I put in a certain kind of chirpped signal, I can use this for temperature and noise metrology. But that's not why I'm posting about this here. What I need is a modular synth enthusiast who's weird enough to actually want to play this instrument, to bring their synth modules into a lab with a dilution fridge and plug it all together, actually record a performance, stream it to the web, all that kind of stuff.
I'm writing a white paper right now to try to get funding to build this for metrology purposes. But if it were a thing that had some cultural significance where people are actually listening to music from the machine, I think it will help with getting the funding people's attention as well.
If I can find the right collaborator, this will turn into a paper we can publish in some applied physics journal, maybe something like Applied Physics Letters. Also, if we make a film about it, I have a finite Erdos-Bacon number and then any collaborator would as well.
#Anarchists only. #Musicians must be anti-intellectual property and anti capitalist in principle, although we can definitely try to get funding to support the work and pay people. I really just mean anti-copyright and anti-patent. We're not going to put this stuff behind a paywall, we're going to try to get funding from government and non-profit grants and donations. And then we can stay off the commercial platforms and just put up self-hosted videos. It's quantum noise #metrology as social media. I have a bunch of domains we can use for this, both in regards to metrology and #quantum noise.
#TIL that one bit weighs one #quectogram. So I am assuming we will need to reduce the size of our bit or assume that we cannot store infinite amounts. #physics#metrology#scale
