I don't know (and don't need you to elaborate on) exactly what you're referring to in that last sentence, but I suspect you are confusing Eric W. Weisstein with Eric Weisstein.
Lazy, or more efficient? If you type a time and hit start, you're not microwaving until you're done with all the buttons. If you hit "QS" a bunch to reach the duration instead, the microwave starts cooking immediately on the first press. Your nuggets get done a whole second earlier!
Switching the direction that you're twiddling the bolts would have to change the direction of any movement. But by symmetry, clockwise and counterclockwise twiddling are identical (looking down on the head of each bolt, one is always moving clockwise and one is always moving counterclockwise). So there must be no in/out movement at all.
This is similar to how I guessed the answer - it's a symmetric system, so there's no reason why it would be one direction over the other and so logically there would be no movement.
Relative to the handedness, one bolt is always moving with it, one bolt is always moving against it. Switching direction doesn't change that. So switching direction can't change whether it moves inward or outward.
Couldn't you transform twiddling one way into twiddling the other way by reflecting through a mirror and turning the bolts 180 degrees end-over-end? If you start with the bolts moving North, the mirroring makes them go South, and turning them around makes them go North again, but now you're twiddling the other way. So the bolts would have to go North no matter which way you twiddle them, so either twiddling is not reversible (which is a repugnant proposition) or they must have a speed of 0.
some math because I'm curious:
If you draw down and replace 50% of the water every day, each molecule has a 1/2 chance of sticking around.
After 3 months that's 1/(2^90).
A 5 gallon pot contains around 2^87 water molecules.
So after 3 months there's basically none of the original liquid left.
The Xbox came out when the PS2 did. When it came time for the next generation, Sony went with the obvious PS3. Microsoft of course couldn't compete with an "Xbox 2" vs a "PS3", and they couldn't skip right to "Xbox 3", so they called it the "Xbox 360", which was frankly genius because it had the 3 there anyway and put it on the same level in consumers' eyes.
But after that it all fell apart -- they had no good options. They still couldn't jump to "Xbox 4". Maybe "720" would have worked. Someone decided to have a clean break and restart at "One" but of course that fell apart immediately at "Two". So another clean break to "Series..". And by that point it's so screwy they've lost any chance of fixing it...
>Microsoft of course couldn't compete with an "Xbox 2" vs a "PS3", and they couldn't skip right to "Xbox 3"
Nope, it all goes back to Microsoft not naming the 360 "Xbox 3" with some lame excuse for why it did so. Yes, everyone would have laughed, but no one would remember or care today that the "Xbox 5" isn't actually the fifth Xbox.
An alternative that Microsoft missed, from Reddit:
>They could have named the Xbox Series X the Xbox 5 and said it was because they counted the One X as the 4th gen Xbox.
Exactly - or they could have released a rare, ignored souped up Xbox as the "Xbox 2" and done the "Xbox 3".
The 360 was a good "fix" for the problem but not going to something like Xbox13 or Xbox2013 (though year based names were on the out by then) - anything other than "Xbox One" (Xbone would have been better).
I still don't know how the various versions work and apply to the Series SeX.
They can't call it the <something else> Box because they don't want people to think of it as a Microsoft Device.
Nintendo can go from Nintendo 3DS to Nintendo Switch because the brand is Nintendo.
Microsoft clearly considers the brand "Microsoft" to be poison ivy to gamers, and always brands their gaming hardware as "Xbox" as if that were the company name. Going to Ybox would kill their brand and put them back at square one.
A&W tried to make a 1/3 pound burger to compete with the McDonald’s Quarter Pounder but it failed because people thought it was smaller, because 3 is smaller than 4.
I think "Xbox 4" coming after "Xbox 360" would have been the cleanest break. It would have been fine. Or heck, jump straight to "Xbox 5" if they really think the number in the name is the main point of comparison with the PlayStation.
Why not? If your starting point is completely static compared to the point mass and your aspect area isn’t zero, you’re going to fall directly down towards the point mass and are going to hit it.
If it was a point mass, and you had exactly zero horizontal motion relative to it, you'd go right through and out the other side.
Well, except for relativity turning it into a black hole with a Schwarzschild radius of 8.87 mm so it won't be "point-like".
But most of the disintegrate sheen of plasma that used to be your body would have had some horizontal motion compared to it, even if only due to you starting off as an extended body.
> This is no good. Let me just try reverting to a version from a month ago. Nothing. Three months ago? Nothing. Still failing. A year ago? Zilch.
Reverting your own code, but still using a broken PostHog update from that same day? For me, the lesson is to make sure that I can revert everything, including dependencies.
Years ago, IT at the company I was working at force-pushed a browser extension that did this same trick, but the extension vendor in question didn't even bother loading over https.
Edit: the extension's manifest gave it nearly every permission, on every web site, including internal ones
"An oscillator generates a 12-volt, 200-kilohertz (kHz) pulsed electrical signal, which is applied to a small plate on one side of the blade. The signal is transferred to the blade by capacitive coupling. A plate on the other side of the blade picks up the signal and sends it to a threshold detector. If a human contacts the blade, the signal will fall below the threshold. After signal loss for 25 micro seconds (µs), the detector will fire. A tooth on a 10-inch circular blade rotating at 4000 RPM will stay in contact with the approximate width of a fingertip for 100 µs. The 200-kHz signal will have up to 10 pulses during that time, and should be able to detect contact with just one tooth.[4] When the brake activates, a spring pushes an aluminum block into the blade. The block is normally held away from the blade by a wire, but during braking an electric current instantly melts the wire, similar to a fuse blowing."
Jensen Huang owns 3.8% of Nvidia and 3.8% of the voting power
Tim Cook owns 0.021% of Apple and 0.021% of the voting power
Previously, Steve Jobs owned 0.6% of Apple and 0.6% of the voting power
So yeah, there's a structural difference here and Meta is much closer to being owned, managed, and controlled by Zuck alone
