So quit trying to measure the speed of gravity waiting for and hoping to catch high speed gravitational events far away in the sky, and accurately plotting positions too, or computing them from a system of equations, for which you still need measurements of some kind, even if less accurate, for all the 7 actors involved in the system of 7 equations). So the best chances to measure speed of gravity are in the lab, repeating Cavendish's experiments (see the wikipedia page). Just like in the formula for attraction between electric charges, F=k.q1.q2/r^2, k is the Coulomb constant, equal to 1/(4.Pi.epsilon), you could measure the speed of light by jerking either the large charge or the small charge and plotting the force on the other vs. distance of charge on a high speed camera, you might be able to do the same experiment with the Cavendish setup relating to masses instead of electric charges, where F=k.m1.m2/r^2, k is the gravitational constant measured when the masses are sitting still compared to each. However it's really hard to get sensitive force measurements down to picograms on tons of weight (as in measuring weight to 2153.0000000000000000017 kg accuracy, that's too many digits), and while with charges you can concentrate a lot of charge and have small weight into a small object, easily jerked and position changed suddenly, with gravity you must have a heavy ball that's hard to jerk if you want to measure the quartz hair suspended torsion force on the smaller one, at say 0.0215300000000000017 kg. It's like you have to blast the heavy ball away from the sensitively suspended little one with an explosive pull through a strong shaft that does not shatter from the pull (you have to pull, you can't push by having an explosion blast going on between the balls), (capturing its motion on an ultrahighspeed camera,) to get a sudden effect, and then watch as the little balls inertia damps almost all of it away, and barely starts moving the torsional sensor. The torsional recovery force accelerating the mass back is extremely small, but you might be able to compute when it started from plotting and extrapolating back the accelerating positions vs.time. Such an experiment is extremely impossible to conduct, as even with the measurement of light, such as Fizeau, he gets a couple miles of distance by sending light out of the lab with a mirror for a few miles, then back into the lab, and now he's got a couple miles of path length vs. time, as opposed to the Cavendish experiment of 2 inches or 2 feet.
The most bad-ass server I've ever had the pleasure of working with was a Digital VAX 11/750 generations ago. It was *built* to be reliable from the very first rivet.
Oh sure, my pocket phone has far more power, memory, and storage. Despite the ample square footage of my "McMansion" house, It would not have fit in my kitchen. It ate power like global warming really was a myth. But as a server, it was in its own class.
It would automatically detect memory that was failing and rebuild from memory (like ECC) but then would remap that address so it would no longer be used.
You could upgrade its CPUs one at a time without shutting it down.
It was like a hoover with data, versioning files was intrinsic to how the O/S worked.
One time, the A/C in the computer room went out. It mapped *everything* in RAM to disk as the temperature rose and the chips became unreliable. We literally pulled the plug on it because it was completely unresponsive, as all operations were working directly off HDD. When the A/C was fixed and it was powered up late that night, it spooled all of RAM out of the HDD swap, and everybody's workstation resumed exactly where they had left off that afternoon - we couldn't find any data loss at all.
I will forever bow in deference to the greatest server I have ever had the pleasure of working on. How HP managed to acquire such a legacy and turn its back... part of me cries inside.
A bat has no idea there is such a thing as light in the Universe, and misses out on looking at distant galaxies. I wonder how many such interactions there are that we have no sensors for. I mean a bat could still detect light just like we detect radio waves through a radio speaker, but it would be a hard job for him to adapt an speaker to depict Hubble telescope images in ultrasound for his ears to see. Picture a Hubble telescope image viewed in ultrasound, then transduced back into light for us. The image resolution must be horrible for bats, if they look at stuff like we look at pregnancy ultrasounds, but they are able to catch bugs with their sound vision, so maybe there is ways to go with our pregnancy images to get more quality. So just because we can't see an interaction with our present biological sensors like eyeballs and technological sensors like infrared detectors it does not mean it's not possible to transduce it to the other methods, and we probably know of all interactions there are out there, but there is always a possibility of something not very interacting escaping our attention, and it may be a while before we discover it, just like it may take thousands of years for bats with intelligence equivalent to humans, to happen upon light sensors, even if they know all about lightning strike thunders.
"Neither Americans nor the rest of the world signed up for a fucking security agency which is no longer under anyone's control except people who feel they can do anything they want."
Uh, the CIA has been pretty much like this since its inception during World War II as the OSS and the CIA immediately after. It was reined in briefly by the Churck and Pike Committees in the 70's but that oversight and those reforms were pretty much rolled back by Reagan. Sure, they got to reach new lows after 9/11 with no hold barred torture, but the CIA has been torturing people through proxies for its entire history, so that wasn't exactly new either.
Not exactly sure why everyone is acting like this is some kind of revelation or anything new, other than its kind of amazing Brennan was foolish enough to admit to it. I predict his career at the CIA will soon come to an end, and he will be replaced with someone with larger brass balls.
The chances you all are gonna change any of this airing your indignation on
The political fervour that is whipped up in the populace, from security theatre / war on terror, the war on drugs, etc, takes a life of its own in a pure democracy.
Who whips up that fervor, the war on drugs wasn't started as a grass roots campaign, for sure, it came from the top. It's the same in the US and UK, I think, certainly with the same dark motivations and same ill-gotten power. Anonymity is a friend to the masses and an enemy to power. Whistle-blowers, leakers and disharmonious speech are threats to the status quo, the same one that provides the wealth they wield to have this alleged long-term view.
I don't disagree with the concept of having a ruling body that is not beholden to the mob, I just haven't seen any mechanism by which that body can be kept honest and magnanimous. That is the same spirit which brought down monarchies to begin with.
I'm certainly too ignorant to decide in what ways the UK system or the US system are better or worse, but in this particular example I do not see any significant difference.
Do those phones use custom or off-the-shelf displays?
I thought that Oculus had always planned on using off-the-shelf cell phone displays. If they can keep the retail price under $300, they will sell a ton of units.
I joined Mensa, and at my first meeting I brought 'smarties' and 'smart food' to share. Nobody thought it was funny and they were kind of annoyed. I didn't come back.
"We are going to proceed with at least two locations in parallel, just in case one of them encounters some issues after breaking ground," Musk said. He said Panasonic was likely to be Tesla's partner in battery production.
The fact that construction started and then stopped makes it sound more like this is that - who else would do such a thing?
Morgan Stanley is excited about the potential use of gigafactory batteries for home energy storage and grid independence, and thinks they might make more on that than on cars. (I would have thought good old lead acid car batteries were cheaper for this?)
But it makes more sense to filter the air at the inlet if you can, or at least as it recirculates through the HVAC system already built into your home. Check your air filter once in a while, people!
It annoys the hell out of me that my books are so damned expensive, which is why I wanted Mars, Ho! to be 100,000 words. I'd hoped that possibly Baen might publish it so it would be, oddly, far cheaper. I can buy a copy of Andy Wier's excellent novel The Martian from Barnes and Noble or Amazon for less than I can get a copy of my own Paxil Diaries from my printer, and Wier's book is a lot longer.
