Unless it's on a piano. The region known as the temperament is tuned in a logical manner, but from then on, the tuner applies a bizarrely difficult series of modifications to obviate discordant resonances. This is known as 'Keyboard Stretch'. For example, A 440 could still be near to 440, but...

Really, this is the kind of answer I'd hoped for in the past when I ask about a rather mechanical explanation of gravity that I've toyed with for 50 years. Dale, you've suggested my post might be theory development, or some such term. I'm not remotely qualified to achieve...
That's a good question.
I visualize a line from a point at the centre of the Earth going through a particle at the surface, and on to a distant or fixed star*. Take this to mean a visible object not in our galaxy. I assume the surface particle is moving away from that distant object for...
Not so much confusing, as failing to make clear the question details. It's just that an accelerated object, in my limited understanding, undergoes a change in the direction of motion. I wondered what the effects might be on something that was decelerating in all directions simultaneously...
Hence, 'Fixed Stars' being in quotes.
I suppose it's much the same as calling gravity a force. I have to confess I haven't heard the term for a very long time, but it was often used, even in the heavier end of science books for the layman a couple of decades ago. I had a feeling back then that...
I've always felt that the concept of the Universe changing scale* is no harder to accept than learning it was expanding. Both take quite a leap of faith. In such a universe, spacetime - whatever it turns out to be - would have a limitless sink-hole and limitless energy proportional to the...
After almost a lifetime's interest in gravity, and some years ago, this forum gave me a steer to a paper being reviewed by an American professor. It was all about the inflow into matter of some kind of fluid spacetime, and was uncannily like the notion I'd had in my student days. The prime...
One is mindful of that picture of the Pope kneeling in front of Stephen Hawking's chair. He, the Pope, said something along the lines of it was okay to model back to the big bang but please don't theorize on a time before that. The professor said later that he didn't let on that he and others...
Given that measuring the speed of light over short distances requires a very precise clock, is there any significant time taken for the photons to be 'processed'* by the mirror to send them on their return journey?
*I've just read a little on what takes place but it seemed even more complex...
I was just going to suggest introducing the CMB into the discussion. The use of the CMB to stabilize a NASA U2 aircraft to better measure the . . . CMB has fascinated me for years. It almost seemed to suggest some sort of spacetime datum, but of course, that's not possible. :-(

Now we're getting to the point. Or two points if talking about a Taser or stun-gun. (Sorry ;-) ) By the way, they're different devices.
Current limiting resistor? Some of the stun guns I've seen demonstrated are downright vicious. i.e., if the points are touching the flesh, the voltage is...
