  1. Motor burned out in 10 years? I wouldn't give that a good grade unless you were raping it on a daily basis.
  2. Of course it needs one. Containment domes shield from aircraft impacts, earthquakes, hydrogen explosions, fission product escape, etc. It's not just about steam explosions. It's a tomb in case anything goes horribly wrong and the interior needs to be shielded from the rest of the world. Every nuclear power plant absolutely has to have a containment dome. No discussion about that.
  3. I have no idea. Houses in Croatia are built out of bricks and reinforced concrete, so it can't be judged by that. Maybe this thing would've peeled of parts of a typical cardboard house at this distance, I don't know. It's probably barely F1 or F1.
  4. I'm curious about the structural integrity of this lump. http://blogs.esa.int/rosetta/2014/07/29/cometwatch-28-july/
  5. That's good news, but I'd be happier if they would spend some money on building containment domes over all of the reactors in Beloyarsk. I'm all for nuclear energy, but I don't like Russian stance on containments. It's a nuclear fission reactor, not a cake factory.
  6. I didn't want to open a new thread for this. This was two days ago relatively close to me. A tourist from Hungary took the video. What you're seeing is a tornadic waterspout, in fact a real tornado stronger than those tornados people typically call waterspouts.
  7. So only theoretical physicists should be able to talk about this? I've been reading about this in the 90s and I remember it's one of those things you hear in older documentary movies. OK, I'm wrong, I've mixed something. Why are you constantly behaving like a bickering old lady? Normal people provide others with a link. You're being a pain in the ass all the time and behaving like a god almighty towards everyone. You'd be a lousy teacher. Please stop with such behaviour or I'll report you the next time. I'm sick of it. Also, you could finally say what's the state of matter of a single electron whizzing by Neptune. I've never heard that lonesome elementary particles represent a state of matter, but what the hell do I know, right?
  8. I really doubt that's the case. Someone should do the math, but as far as I know, you'd need very small black holes (artificial) for the tidal forces before the event horizon to be so huge that a human body od 180 cm would be torn apart. So an electron is a state of matter? No, it's not. It's an electron. State of matter requires a system of particles. Therefore a black hole can not be a state of matter. It's a point surrounded by a horribly warped spacetime. You're using semantics to get your way, and it's not the first time.
  9. App? You mean there's a mobile version? I've only used the PC program for a looong time.
  10. Also, for all but very small black holes, crossing the event horizon of a lonesome black hole would be just a fancy visual display (if Firewall hypothesis isn't true). Horror of pulling stuff apart comes after that, close to the singularity where the gravity gradient is enough for human-sized objects to experience high tidal forces.
  11. Only by scribbling on the paper. No information can reach us from inside of the event horizon. Current knowledge supports the notion that matter is totally crushed into a point because even neutron pressure is not enough to stop the contraction. By the time event horizon is formed, matter as we know it can't exist.

  13. Event horizon is space, which is "nothing" by traditional sense of speaking (let's ignore particles foaming in vacuum), and the center is singularity, which could also be called nothing because it has zero dimensions. It's a point. According to our current knowledge, of course. Who knows what's the actual bussiness inside. I was always fond of hypothesis that it's still a kind of star, but a totally degenerated and very small. So, curved space... that's not a state of matter.
  14. We don't have actual bagels here, but there are things close to it. Cinnamon and raisins for me - a truckload of warm ones, please. How do you pronounce it? http://www.youtube.com/watch?v=2dwM8FV0f7E
  15. They're very loud, too. I was stunned because I thought all the hype must be because of something, I don't know... good. But it was all a good marketing. Somehow I think this is not a good idea.
  16. Don't worry, it won't be there for long! Waiter, there's a Goomba in my soup!
  17. Well I'm sort of a coordinator here, and can't do anything else. Others seem to got awfully quiet. Yes, we need someone who could write a script that would collect the timestamped data pouring in from various sensors, Geiger-Müller tube included.
  18. Piston compressing air which blows at you through a valve. Not terribly efficient, and quite noisy, too.
  19. Not really. You can get hit by one gamma ray per second, or a million of them per second. We already established that we're talking about fixed frequencies for both gamma and radiowaves.
  20. Therefore it isn't possible, because the question was about model rockets.
  21. As xcorps said, multiple factors, and they aren't the same for radiowaves and gamma rays, as they're really different.
  22. You should check out other videos on that channel. That should explain all of this.
