[QUOTE=Brosi;16367656]I have a science question for the science nerds of the science thread. Its pretty sciency. I want to know how they accurately measure temperature. In the CELSIUS system, 0 degrees is based on when water freezes, and 100 degrees is when water boils. However, water only boils because of its impurities, distilled water can't boil. So when they established the measuring system, what was the amount of impurities in the control water? Did they even know then, or did they just use any left over piss? Because as far as I know this could effect the whole temperature system with inaccuracy, and I'm pretty sure there are some experiments that need National Socialisticly accurate measurements. SO WHAT DID THEY DOOOOO?[/QUOTE] ppppppretty sure distilled water can boil
[QUOTE=Beafman;16366591]Here is the epic anti-matter explosion from the movie Angels and Demons (pretty big spoilers if you haven't seen it) Pretty powerful when you release 100% pure energy, isen't it?

(Anti-matter of that size should take out a good chunk of the earth. A Europe sized chunk of the earth.)

if distilled water cant boil then how did it get distilled
What are the properties of "Bose Einstein Condensates"? I know what they are, but I just don't know what they do. [editline]06:20AM[/editline] [QUOTE=BAZ;16368411]if distilled water cant boil then how did it get distilled[/QUOTE] hax, of course.

[QUOTE=sp00k!;16368527]I'm pretty sure the author pretty much completely ignored what antimatter actually is/does. Can someone back me up?[/QUOTE] Antimatter is completely real and is not at all like that. It is not a smoky magical substance. If a quantity of antimatter that large were to touch real matter, it would in fact explode. However, that explosion would most likely detonate over a huge area. And that "antimatter" looks to be the size of a tennis ball. An explosion of antimatter that large would at the very least destroy the whole of Italy. I know this because PBS tells me so.
[QUOTE=sp00k!;16368527]I'm pretty sure the author pretty much completely ignored what antimatter actually is/does. Can someone back me up?[/QUOTE] Yeah that's right. Let me quote my source: [quote=http://en.wikipedia.org/wiki/Angels_and_demons]Angels & Demons is a [...] novel written by American author [highlight]Dan Brown[/highlight].[/quote]
Anti-matter just annihilates into pure energy when it comes into contact with matter.

I know this because PBS tells me so.[/QUOTE] The anti-matter in Angels and Demons were only small particles captured. It is just zoomed in when it explodes. Victoria says that the explosion is about a 5 kiloton nuclear warhead, so it would only have to be a very small amount needed for that blast. It has been calculated that if you had 1 kg of anti-matter and let it come into contract with matter, it would explode with the force of a 47 megaton nuclear fusion bomb. It's just a little under the Tsar bomba the russians exploded in 1962. Although that used more then 100 kg of plutonium: [media]http://www.youtube.com/watch?v=H9AMtUeyDP0[/media]

[QUOTE=bravehat;16368920]Anti-matter just annihilates into pure energy when it comes into contact with matter.[/QUOTE] Not quite. About half of it gets turned into neutrinos, which are harmless. So any antimatter bomb's yield is about half its theoretical yield.
[QUOTE=JohnnyMo1;16369716]Not quite. About half of it gets turned into neutrinos, which are harmless. So any antimatter bomb's yield is about half its theoretical yield.[/QUOTE] well 24.5 megatons are still quite powerful if you ask me xD
It just started raining here. Can someone do some science in such a way that it doesn't rain here anymore?
If an antiproton came in contact with a proton, both of these would get completely annihilated. So, would a bomb of antimatter just be obliverated by the air anyway?

[QUOTE=Billiam;16370437]I believe you're suppose to store them in a vacuum and suspend them with electromagnetism? Or something like that.[/QUOTE] Also, another thought. AntiH is said to have pretty much the same characteristics as H, so, it would explode the same way. I don't see an explosion of antimatter being able to destroy Europe as it's said to unless it was a 1 Gigaton explosion.

Some believe parts of the universe is filled with anti-matter which is in large groups. However since there is none around us, some believe it could be in some of the galaxies around us instead. There is anti-matter just floating around out in space, however I think it would be pretty annoying for a space ship to just hit a particle of it and being destroyed by it xD [editline]02:21PM[/editline] [QUOTE=Kendra;16370537]Also, another thought.

what would you see if you somehow managed to reach the physical edge of the universe? If there even is one that is. Does the National Geographic move "Journey To The Edge Of The Universe" depict that accurately?

I don't see an explosion of antimatter being able to destroy Europe as it's said to unless it was a 1 Gigaton explosion.[/QUOTE] You have to think what 'explode' actually means. When hydrogen explodes, all it is doing is combining with oxygen molecules and releasing energy. You're right, Anti-hydrogen is chemically identical to hydrogen so it would explode or burn, but you'd need anti oxygen molecules for it to bind with. Anti-H wouldn't chemically burn in our environment because there's nothing for it to burn with. What will happen is it will annihilate with the molecules in the atmosphere, causing it to explode, just nothing like a chemical explosion, and a fuckton more energy.
[QUOTE=SGTNAPALM;16368423]What are the properties of "Bose Einstein Condensates"? I know what they are, but I just don't know what they do.[/QUOTE] They are very cold and a majority of the bosonic atoms is in the same physical state - The ground state. This allows for example ultra-precises interferometry. And because of the atoms being all in the same quantum state, you have a quantum-system in macroscopic size: You can see a BEC. [editline]03:25PM[/editline] [QUOTE=bravehat;16368920]Anti-matter just annihilates into pure energy when it comes into contact with matter.[/QUOTE] In a more complete way: It annihilates to light and neutrinos.
