That is times 10 (longer) for each 20degC lower average operating temperature!

P.s. I see now, you did the "manual" thing this thread moves faster than I am

Well, last I checked, no change in the charge of the electron or change of speed of light has occurred. Some "inventors" seem to think so. Of course there will be new valuable inventions, based on science, and they will progress the art.

There's so much cool stuff one can do without needing to rewrite physics, which already being engineered at levels that boggle the mind, including the very device you're using to view this thread. Of course, that actually requires one to be pretty well studied on what is already known. But at the mundane size scales we work at, outside of JNeutron's employer, one should assume that we're working in realms that are well described, even if we don't necessarily know which phenomenon(s) are at play.

That's not to say it's all known, and when we add the listener to the equation everything gets much more fuzzy. Of course, humans also follow the laws of physics at their most fundamental (it's all chemistry/physics at the end), but complexity masks what's going on, of course.

Not disagreeing with that latter, but I know an engineer of some standing who has questioned the light constant for many years and keeps bringing it up, and he is no 'inventor' and a transmission expert. Maybe it is time fluctuations that explains minor variations, so maybe light is constant and time is not? Who knows? But I won't adopt a rigid position on it. I am reminded that QM allows for time to have some inherent fuzziness.

Last person who went on record with a faster than light measurement lost his job when the loose connector on an equipment rack was found!

However issues that science can explain are being found all the time, for example Hubble Space Telescope one of 16 suffering data-scrambling sensor error • The Register

Rather embarassing it went unnoticed for so long, but correctable. Good Science works!

Sure. But what makes science interesting is that we can have on observation that cannot be explained at that time, and then looking for explanations and finding them. In the meantime, the science might look a bit messy and there will be perhaps a little bit of infighting, a few egos here and there taking positions, and yet hopefully emerge at the other side with a consensus and a hypothesis that can stand the scrutiny. So science is as much about the journey, that it is about the destination.

Science is mainly about the journey. Scientists build a giant apparatus, run it for a few months then say 'this is great, we now need a much bigger one'. Cern hasn't been shut down now the decayed carcass of the Higgs Boson has been found. They want to bigger better, faster collisions to see what particle roadkill they find.

None of which of course has very much bearing on the 20Hz-20kHz world of the human hearing. At least until they work out how to implant better ears into us.

Whatever works, works! No need to attack, just because you do not understand WHY it works!
