> orchestras specializing in older music may sometimes tune in the tuning close to the one for which the piece was originally written, which may range from 415 Hz to 470 Hz). I can say as someone who performs a lot of Baroque music (c. 1600 - 1750) that there is a relatively common standard of A=415 for music of this period. A=415 is often referred to as "Baroque pitch." This mainly applies to ensembles that speciali…

Opera singer here - you must be playing in North America. In Germany tunings range from 436 to 444, depending on what you're playing. Most theaters tune to 442. One thing that gets opera singers (like me) up in a knot about this, is that the human voice is not a tune-able instrument. There are registration issues in fixed frequency ranges, which we can't change. At A440, a register shift happens a quarter tone lower…

Couldn't the Kilogram be derived from the Liter, which in turn can be derived from the Meter? From what I recall: - 1 Liter of pure water at 4 Celsius is 1 Kg. - 1 Liter is a cube with 10 cm on each side.

Generating a perfectly homogenous 4C over an environment large enough to contain a kilogram of any useful substance is going to be incredibly difficult and mearusing it even moreso. There's a reason every unit of measurement aside from mass is derived from an electrical property; we can measure electrical properties down to ridiculous precision, measurements small enough that all measurement uncertainty is removed.

I wouldn't be so sure there is nothing special about the duration of a second. It comes from dividing a day into two sets of 12, then those 12 into five sets of 12 (12x5=60), then those 60s into 60 each. We know our bodies do follow circadian rhythms, so you have the initial link to length of day. Then everything else is split into sets of 12, a number with exceptional properties that natural selection may optimize t…

It comes from dividing a day into two sets of 12, then those 12 into five sets of 12 (12x5=60), then those 60s into 60 each. That's exactly why, actually. This is what the second was once defined as, but the problem is that the length of a day varies slightly - up to ~8s depending on the time of year and other seconds. As the article men…

  F0 = the pitch of A4 on the when there are 12 hours of day/night
  k  = a scaling factor that determines how much to change the pitch based on duration of the variable second

Because it requires a core assumption of anti-intellectualism. It doesn't bother you when friends and family are sold on something that is baseless and are completely opposed to actually researching it and at the very least becoming more skeptical about it?

Nah. We evolved to be superstitious. It's evolutionarily advantageous. Why? Because it's much less costly to develop a random incorrect superstition than it is to miss an important correlation. How harmful is it to meditate to 432Hz compared to... well maybe without that superstition they wouldn't even meditate at all. It's probably advantageous, even though it's bullshit. As long as they aren't engaging in harmful b…

And you actually pointed out why those two things are different. We understand Star Wars is space wizards. New-agers do not understand that their beliefs are mostly bogus.

Luckily for us software development is a completely rational discipline, and is immune to fads, fashions, rhetoric, snake oil, and beliefs with no empirical foundation.
