When you read enough SF, the scary becomes less so. That's one of the many points of literature, and one of the main points of SF: extend and exercise the imagination. In retrospect, it was only a matter of time until somebody got interested enough to leave our planet before their time.

You might like this then because it combines the tracking idea with books.
They use a catch and release meme. So instead of spending money, "release" a book somewhere and check it gets caught.

Didn't understand a bit of that, I don't have the proper education. But I do have a question.

In the example(s?) given I only saw the plus sign. I assume it can be done with subtraction, but what about other stuff like multiplication and division? Maybe at some point it can be extended beyond basic algebra? I mean basic algebra in terms of the problem equation, not the calculation of the solution.

A great idea. I have also wondered about that possibility. Perhaps some of the trawlers which are overfishing the seas could be re-purposed. Start with the ones that drag the ocean floor and leave behind a wasteland for the sake of the few fish they keep, killing everything else and throwing it back.

That skydive video is pretty awesome (though it's a shame the camera didn't have a stabilizer of some sort).

[edit: about metronomes. (few cross-posts in the same time)]

Hahahaha that is wonderful! I almost died of laughing when at minute 2:05 (about) all looked synchronized, except the last one in the second row from the front, which was moving totally wrong, like in the movies with Laurel and Hardy. "Unfortunately" it "solved" itself till the end of the movie. I still puzzles me how they can tell the left tick from the right tick, most probably they use ultrasound ticks, when they hit one side, like a "reset" signal (they have to sound the same, like in "must issue the same audible sound on both sides", they can't sound different, like in "are not allowed to". I may not be able to tell the difference, but my daughter's piano teacher would really look upset if the her metronome makes "tick" on the left and "tock" on the right...).

[QUOTE=LaurV;313141][edit: about metronomes. (few cross-posts in the same time)][/QUOTE]
Scrap that! It seems like my brain is too much damaged by production issues... When I watched the video I was thinking to metronomes which are "required" (by customer specification) to beat synchronous (no idea for what, for teaching music in a class, whatever he needs them for, not my business) and I was convinced that what I see in the movie is the factory QA line testing those metronomes before shipping them out... That is why I wondered what technical solution they adopted to make them beating together, and somehow I was thinking they need too much time for it - I could make them going synchronous much faster/sooner.

Meantime I have read the English description linked. That is different story, and sounds even more interesting...

But I am still laughing like an idiot around minute 2:05, I don't know why, I can't stop it!

i sent the metronome piece around to a bunch of people. One of my cousins responded with speculations about the period of the support surface.

[QUOTE] Impressive demo. Interestingly, of the 32 metronomes, there's one holdout that stays 180º out of phase until late in the game.

If you click through to the original YouTube post, it bears a Japanese caption which Google Translate renders, not too badly I suspect, as:

[INDENT] When you move the metronome and put on a table that moves multiple metronome that ticks all the metronome sound at the same time as it is known in sync eventually.


[/INDENT]Close enough. My guess is that it said:[INDENT]

When you start a metronome and put it on a movable table with multiple ticking metronomes, eventually all the metronomes sound at the same time ("in sync").
[/INDENT]
If you look closely you can see the alluded-to movable support scheme for the rear corners of the styrofoam platform - a suspension wire at each corner so that the whole table is a pendulum, with wires that appear to be about a foot long judging by the front crossbeam (rear one's up out of view). For what it's worth, I get that this should give a natural frequency for the table (1 / 2pi ) * sqrt (g/l) of about 0.9 hz whereas I time the metronomes at 1.33 hz. Wouldn't want 'em matched to table frequency, I suspect -- table might go nuts, or else conceivably (rusty on this) might exactly track the metronome bobs so their swing angle became zero and they'd cease to tick...


If the metronomes weren't powered, I'd expect them to act as a Vibration Eliminator to kill the swing of the table -- but with them being the energy [I]source[/I].... FWIW as set up in the video the table swings in opposition to the metronome bobs.


[/QUOTE]

He says it is OK to post this part of his message. I am just curious if any of the math/science people want to take up the question of what would happen if the swinging support matched the metronomes' timing.

We wonder how close each metronome has to be to the others (in Hz) for this to work.

We wish we worked in that lab!

Good question. I had supposed that they were set nominally the same, and that phase differences were the meat of the matter.

Someone on my cousin's mailing list responded that this experiment only worked because the metronomes are Japanese. If they were American they would still be out of step.

That is plagiarized from an year-old comment on youtube:
[QUOTE]It is because they are all Japanese metronomes. Their culture teaches conformity in every day life.If they were American metronomes, some would chose to only move in one direction; to stubbornly not move at all; to orientate themselves backwards; to head/hand standing... etc... LOL[/QUOTE]
or this on, newer:

[QUOTE]This video shows the process of going from American to Asian.[/QUOTE]I love the last one, and I bet is valid not only for Americans, but for everyone, (Romanians including), especially for Latins, maybe some of you still remember the video which was in circulation years ago about Italy joining the EU, it was really famous (goggling for it) ([URL="http://www.youtube.com/watch?v=HHWBL9_alKs"]found it[/URL]!) It fits our society and culture in every aspect...

It's true! I was in Italy for two weeks for a class history trip. We were taking two vans back to Fiumicino. When we got there, we told a teacher in the other van, "Holy ****! Our driver was driving 100 MPH!". He asked us, "Are you sure that wasn't 100 KPH?", and we replied, "No no no, it was 1[I]60[/I] KPH."

[quote]One day, high above Arizona , we were monitoring the radio traffic of all the mortal airplanes below us. First, a Cessna pilot asked the air traffic controllers to check his ground speed. 'Ninety knots,' ATC replied. A twin Bonanza soon made the same request. 'One-twenty on the ground,' was the reply. To our surprise, a navy F-18 came over the radio with a ground speed check. I knew exactly what he was doing. Of course, he had a ground speed indicator in his cockpit, but he wanted to let all the bug-smashers in the valley know what real speed was 'Dusty 52, we show you at 620 on the ground,' ATC responded. The situation was too ripe. I heard the click of Walter's mike button in the rear seat. In his most innocent voice, Walter startled the controller by asking for a ground speed check from 81,000 feet, clearly above controlled airspace. In a cool, professional voice, the controller replied, ' Aspen 20, I show you at 1,982 knots on the ground.' We did not hear another transmission on that frequency all the way to the coast.[/quote]

[QUOTE=Uncwilly;313142]Yes, about the same elevation as the Hollywood sign. Got to see much of the looping around. Looking down on all of the folks at the Observatory was fun. It was quite hot, the fire department rescued a person off of a ridge (they had heat stroke) by helicopter and treated many others.[/QUOTE]
