someone has to invent a truly digital speaker that eliminates the need for a DAC altogether, have the bits themselves push the cone into position somehow I don’t know
Just realized you can extend x^x to the negatives this way, very neat!
i was kind of curious about that little peak there. Wolfram Alpha says it's at -1/e.
what if i dyed my hair black
I predict it would result in you having black hair.
yeah but would I be hot
if you're in the sun
since the ionosphere and the ground are conductive but the air in between isn’t, could we use the earth as a giant capacitor to store power?
Telsa (the man not the company) planned to do with to enable wireless transfer of power.
I don’t see how you could do it wirelessly
Basically, with a REALLY big Tesla coil — the idea wasn’t so much to store power as to use the ionosphere as the capacitor in a resonant LC circuit. The energy being pumped into the ionosphere could then (hypothetically) be tapped into by circuits tuned to the same resonant frequency
but doesn’t an LC circuit need an inductor and wouldn’t you need to connect it to the capacitor?
The coil is the inductor. It doesn’t need to be directly connected to a capacitor, since it works off the stray (or “parasitic”) capacitance to the environment — the idea behind the tower at Wardenclyffe was to be big enough to meaningfully couple to the ionosphere in this way
the ionosphere isn’t a capacitor, the ionosphere and the ground with air between them is. I don’t see how you could form an LC circuit with that unless you physically connect an inductor to the ionosphere and the ground
Yeah, and the Wardenclyffe tower was on the ground. The tower itself would’ve had stray capacitance to it’s environment, same as all Tesla coils (and all electrical systems for that matter), and if the tower was big enough and high enough power, then “the environment” would include the ionosphere, allowing it to interact and charge to flow and yadda yadda.
Bear in mind though that this might be total nonsense. I like to imagine Wardenclyffe would’ve worked, or at least produced some interesting results had it ever been turned on, but it’s extremely possible and probably even likely that Tesla was just dead wrong. The notion of a high frequency resonant circuit coupling to the ionosphere is certainly plausible — at least, there’s no reason it *shouldn’t* work, beyond the inherent challenges of doing so — but even if you could, there’s not *really* any reason to think it would’ve enabled the worldwide free wireless power Tesla was going for

apparently the revolver was standard issue for the NYPD until 1994!, which seems just insane. in the miltary semiautomatics were standard issue in WW2! during the peak of the late 20th century crime wave, cops were carrying around cowboy guns! no wonder they kill so many people these days, they used to only have 6 shots, gotta make em count
how do I estimate the breakdown voltage over kilometers of air?
wikipedia says paschen's law doesn't apply and instead meek's crition is used but declines to tell me what that is
Fucked up that those ultrasound microphones cost $6000 USD, I want to record my plants clicking at 80KHZ or whatever
a normal microphone doesn't pick up ultrasound?
