Cosmic Ray Detector - STAR Symposium Cloud Chamber Posted by: ebdavidson1 Video duration: 236 seconds Clips of the particle decays caused by high energy radiation that comes from space and passes through us all the time! Come see our cosmic ray detector! Learn about cosmic rays and much much more at the STAR Symposium! Saturday Oct 3, 2009 Vari Hall, York University, Toronto.

By: saintmichaelsarmoury. on 27 Feb 12, 21:35:41 Also P.S. look up "pyramid texts." They are burial texts found in Sarcophoci in...wait? for it...in pyramids. The consensus is ... By: saintmichaelsarmoury. on 27 Feb 12, 21:32:35 The consensus is that they are tombs. There's an archaeologist taking nap in the other room from me right now (my wife). Even if we accept what you say, that they were not related to burial AT ALL, you can't then substitute another batshit idea that they were cosmic ray detectors. 1. They didn't know about cosmic? radiation. 2. why would they want to shield themselves from it? 3. Just no. -- Since when have ... By: VicktheChick. on 27 Feb 12, 13:49:38 -- Since when have they ever FOUND mummies in the pyramids? THEY HAVEN'T.? Schools just taught the general theory that the pyramids were USED as places to put bodies but there are some convincing books that say they were created instead for regular RITUALS for live people INSTEAD. Why put the equivalent of 100 billion of todays dollars in something that couldn't be USEFUL? They didn't? know ...

By: ebdavidson1. on 24 Mar 11, 20:43:39 well, you definitely can use peltier coolers, as google will tell you. You need a rather large heatsink, however, and it is not as? nice as it is with dry ice Ok, thanks. I love ... By: yellowmetalcyborg. on 24 Mar 11, 20:22:44 Ok, thanks. I love these could chambers, but it's too bad that? you can't really have one as a desktop attraction. I was thinking it would be nice of I could take a peltier module and make a cloud chamber that I wouldn't have to cool with liquid nitrogen or dry ice. I don't really mind if I have to plug it into an outlet. A compressor would be kind of loud... I'm not sure that ... By: ebdavidson1. on 24 Mar 11, 20:11:16 I'm not sure that the efficiency? would be high enough. You would certainly need a lot of power. It would probably be cheaper to use a compressor and coolant. Cheapest and simplest of all - dry ice. Another cheap idea, if you have the means to handle it, would be to use liquid nitrogen, although you need a convenient source and it wouldn't last very long in the tray unless it was well-insulated. Do you think that ... By: yellowmetalcyborg. on 24 Mar 11, 19:50:06 Do you think that peltier cooling of the? bottom would work just as well as dry ice? There is an ... By: VicktheChick. on 13 May 10, 12:50:56 There is an interesting theory that the Great Pyramids of Egypt and Mexico were built as they were to be cosmic ray shelters. Apparently underneath enough concrete? or earth the rays decrease. So freaking? cool! By: wafflegirl506. on 13 Dec 09, 13:55:01 So freaking? cool! its so awesome to ... By: boxa888. on 03 Dec 09, 22:50:29 its so awesome to think we are being hit by these wether we like it or not lol. i find it even more interesting when going sub atomic to the subatomic particles where the neutrinos are like hitting everything millions of times a second and still barely have a nudge on sensory devices because they are barely interfer with anything. tesla said he was? harnessing this particle, he called it a "slightly negative neutron", and surprisingly these particles fall into this in one form or another! You need like 97%, ... By: ebdavidson1. on 03 Dec 09, 22:02:47 You need like 97%, and a high temperature gradient. We got the best results using dry ice at the bottom and just warming the top with? our hands. maybe i was crazy, ... By: boxa888. on 03 Dec 09, 21:38:09 maybe i was crazy, but i saw the same tracks like a cloud chamber, its alot less frequent, but i saw the tracks that you would see in a chamber like that, but maybe it was my imagination lol. maybe ill test it and put it up, fine dry dust of a certain diameter and shake it infront of a window with sun comming through, if it works ill post it. great work by the way!? very impresssive! i tried to build one but i didnt have a extremly evaporative alcohol. seems a little ... By: ebdavidson1. on 03 Dec 09, 16:54:09 seems a little strange... I'm not sure? why dust would be so sensitive. i swear if you make ... By: boxa888. on 30 Nov 09, 03:18:57 i swear if you make the dust off of the couch spray into the air you can see the cosmic rays too, its really hard to see but in the light comming through a window you can see tracks sometimes, first i thought i was crazy but it seemed like it really is happening, anyone else. any way nikola tesla dicovered these particles 30 yrs before hess and even was able to obtain energy from them!i made a simple device to take? the energy from them, tesla called them radiant energy. its easy to build andfree =O q? bonito se ve By: FemAnDFunky. on 12 Nov 09, 19:41:52 =O q? bonito se ve

By: acsial. on 10 Feb 09, 23:18:24 After years of thinking that Unionized employees at universities had the same interests as them, these kids finally smartened up. It's Vulgar Marxism, stupid! The Unions care about THEIR interests, not yours. The NDP is in the pockets of the unions & doesn't give a shit about students. Free tuition would be possible, at current funding levels,? by cutting expendatures ~30%. This could be done with contracting out some services, reducing overstaffing and eliminating overpaid tenured positions.
