  1. "haha, perxenic anhydride. thats an enjoyable concept" http://www.westga.edu/~chem/courses/desc.inorg/490Ja28a/tsld031.htm Now I'm scared.
  2. "'strike' sounds like something a 'god' would do hehe." "Strike" sounds something like U.S. likes doing and "god" sounds like something good ol' Bush thinks he is. )
  3. ...Hmmh. Well, imagine a black hole that's getting quite right all its energy from cosmic background radiation. The more its mass, the colder it is (one solar mass blackhole is about at 60 nanokelvin). Now then, if a blackhole is at a temperature greater than its background (in the case of space about 2.7 Kelvin), it loses more energy than it sucks in. And due to the loss of energy (as I explained earlier), its mass decreases, causing it to become hotter, thereby absorbing even less energy. So the black hole shrinks, and shrinks, and its temperature just keeps rising. And then... BOOM! A huge burst of Hawking radiation. IIRC, it's thought that the final burst happens about at the stage where the event horizon is somewhat smaller than an atom's nucleus, the mass is over 100 million tons and the temperature is approximately 100 000 trillion K. So yes, it's generally thought that black holes go up with a BANG. Check also: http://www.newscientist.com/article.ns?id=dn1617
  4. (From the "Rods from God" article) "According to the Space Command’s Strategic Master Plan, by 2025, the United States will have developed the capability to strike any target on Earth within minutes." Sounds like the ultimate wet dream of George W. Bush, I hope he's not the president when this happens. Speaking of orbital weapons, I've been waiting quite a while for the first orbital rail gun, even a small one, as it's quite fascinating, and rather easy to build and maintain (at least compared to an entire space fortress with lasers and such ).
  5. "i'd like to see perxenic acid act on a piece of wood" I'd imagine the reaction is quite similar to the one of osmium tetroxide. Which means pretty severe.
  6. "no need for debate; i know im right" Heh, at least you're confident about it.
  7. Have perxenates even been manufactured in larger quantities? I read somewhere that barium salts can form interesting intersitial compounds with perxenic acid (or the ion, can't remember) with the xenon-atom trapped inside an insoluble barium salt crystal.
  8. "actually, botulinum toxin a is something like 100 million times more lethal than ricin" Ooh, I sense a debate coming. Yeah, even with similar dispersion, I'd imagine 1ug of botulin A would do more harm than 1ug ricin. I don't think that it would be anywhere near 100 million times more lethal in this scenario though, but more anyway.
  9. "what i do know is that black holes radiate slowly and do not explode!!!" If the mass of the black hole is under certain point, it will lose more energy than it gains (by sucking in the cosmic background radiation). And when it loses more energy than it gains, its mass drops, and when that happens, it will result into losing energy even faster, eventually probably resulting in a final burst of energy. Of course, the black holes of the mass category of a large star, gain (currently) more energy from the CBR than they lose.
  10. "Frankly, all systems of temperature measuring suck compared to Kelvin." I have to agree, though it's easier to say "it's 3 degrees out" than "it's 276 degrees out". "If I turn a M5.0624 (making up a number here) nobody will have a nut that fits it." Yeah, that would drive them nuts! Ahahaha... I'm tired. And who took my meds?
  11. "When 50% H2O2 undergoes a rapid decomposition, it's incredibly impressive." Hope you hadn't "been impressed" by it personally, at least not too close due to accidentally dropping something not-suitable-with-H2O2 to your beaker. )
  12. "black holes blow up?? i thought they just died out due to the hawking radiation?" (from the Wikipedia-site:) "For a black hole of one solar mass, we get an evaporation time of 10^67 years—much longer than the current age of the universe. But for a black hole of 10^11 kg, the evaporation time is about 3 billion years. This is why some astronomers are searching for signs of exploding primordial black holes." Yep. "how do you get a "blow up" power from that?" First of all, the site even tells us how many megatons worth of energy is released. And even if it didn't, note that over 100 tons of matter transforms into energy in a second. Well... I'd call that an explosion. )
  13. I'd imagine things are generally more stable when solid. I'm not sure if this goes with every molecule though. In your solution, there might be slow, yet continuous production of ClO2, which then decomposes. Or then it's something completely else. :I
  14. http://en.wikipedia.org/wiki/Hawking_radiation Whoah, see the end of the page. It seems that a black hole that "lives" only for a second blows up with quite a bang.
  15. So that's what it was. bud noticed it first, probably, and I was quite surprised too. "can ya see the place over in the corner where all the babes are at? I`m in the middle, THAT`s the bar :)" Now now YT, drinking in moderation is OK but when you start seeing your wife as multiple persons, it's time to call the cab.
  16. Got to admit, I like bass, but in moderation. Btw alt, what headphones do you use (you do make some interesting music after all )? Mine are Sennheiser HD 570, very good for listening to classical (or playing CS, which is quite right all I use them for :> ).
  17. http://www.thaigem.com/buyer_diamond.asp - A very comprehensive guide to buying and identifying diamonds. Check out the moissanite part - they're used quite often as fake diamonds.
  18. "What are complex numbers?" Isn't the complex number group just real numbers + imaginary numbers together?
  19. "That stuff is fun. It's fun to show people that water can start a fire." That should prove them that spraying a chemical fire with water isn't necessarily a good option.
  20. I'd imagine you could use carbonate instead of the sulfate? Edit: "well there are perxenates.....but we wont talk about them" Yeah, they're rather unpractical.
  21. "rather it DECOMPOSES RAPIDLY in such a manner than MANY MOLECULES OF GAS are evolved with a great RELEASE OF ENERGY. this is called an EXPLOSION" It's GOOD that you CLARIFIED things for us. Even though, the stuff Nave got might only have traces of ClO2, resulting in rapid decomposition yes, but not necessarily a "proper" exposion.
  22. "I also remember which side you Finns were on .... and why. You are the only enemy Britain ever had that we never attacked." There has been controversy with this in Finland too (you know, the Germany thing). However, Risto Ryti once said that something like "The only way to fight Satan is to fight him with the Devil", referring to Stalin and Hitler. So it was a rather smart move. Now that's what I call an application of the games theory. ) And since Finland is cold and has no tea plantages, I can see why the Brittish didn't attack us. j/k "And Gilded how can one take serious someone from a country that bans donald duck comics because he wore no pants,lives in a country thats shaped like a large testicle,name their children all MIKA,or if girl MIkaela.And have the personality of a lettuce." OK, let's go through the facts here. A) http://www.snopes.com/disney/films/finland.htm Donald Duck was never banned in Finland. Check your facts before posting such nonsense. It has been discussed though, but if Finnish uptightness is compared to that of USA... Well, I'm not going to talk about that. ) B) Mika hasn't been on the most popular boyname list for quite a while. Mikael is currently quite a popular name, and I bet there are quite a few popular names for boys in the US too. And Mikaela? Well, it has NEVER been on the most popular girl names list. And I think I've met one Mikaela in my life. So there. And I personally know know Mikas, and I know quite a bunch of Finnish people. (Name info taken from Finland's Population Registry Database) C) If you have testicles shaped like Finland, go to a doctor. And what do you have against testicles anyway? In the words of Johnny Depp "You're not an eunuch, are you?" D) And for the personality, some even have the personality of pumpkin or cauliflower!
  23. "Not easily deflected." Argh, I'd make a fool of myself less often if there were no physicists around. ) (BTW, does neutron even have absolutely zero electrical charge?) Is there any particle that doesn't have neither electrical charge or magnetic moment that could possibly be used for similar beam weaponry uses as the neutron?
  24. "nonono, barium nitrate." UH-OH. Are you aware that barium nitrate is a) very reactive b) very poisonous (lethal dose ranges from 1 to 15 grams!) c) a very good oxidizer? Go with a sulphate or another relatively safe salt, the nitrate is a HUGE safety risk if mixed with your propellant!
  25. "A similar reaction occurs with iodine and aluminum powder. But the gas given off is incredibly corrosive, yet beautifully violet." Every rose has its thorns. Especially in chemistry. "BEWARE THIS HAS SENT ME TO THE ER" Lol. Judging from the experiments you have shared with us, you're gambling with your life more than George W. Bush is gambling with USA's credibility (if humanly possible).
