Guest Rolling Parts Posted February 8, 2010 Share Posted February 8, 2010 Anyone know why the sky is blue? That's easy, because there are no clouds and it's daytime? Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted February 8, 2010 Share Posted February 8, 2010 The sky is blue because that wavelength of color bends 90 degrees (scatters in all directions actually) and comes towards us, when it hits our dusty atmosphere. Red passes straight through without bending which is why you see it at sunset and sunrise. In short. Dusty skies make the best sunsets.

woldson Posted February 8, 2010 Author Share Posted February 8, 2010 Why is mars red? Kinda funny answer. How about this old crusty that has been debated for years, is glass a soild or liquid? Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted February 8, 2010 Share Posted February 8, 2010 If you leave your fridge open, will the room cool or heat? Quote Link to comment Share on other sites More sharing options...
woldson Posted February 8, 2010 Author Share Posted February 8, 2010 Did ya know that the space between atoms, molicules in a solid such as steel is sooooo vast that if you compress an aircraft carrier do the density amount of a megatron star, it will fit in your pocket?

Guest Rolling Parts Posted February 8, 2010 Share Posted February 8, 2010 Stay the same! Well, if you plugged it in, it will heat the room. Entropy rules! Quote Link to comment Share on other sites More sharing options...
MAG58 Posted February 8, 2010 Share Posted February 8, 2010 Well, if you plugged it in, it will heat the room. Entropy rules! Yep. A fridge isn't 100 percent efficient so it will expel more heat than it can cool. Thus when you open the fridge you heat your room. Quote Link to comment Share on other sites More sharing options...

Guest Rolling Parts Posted February 8, 2010 Share Posted February 8, 2010 That's right! did not think of that. Actually, it always heats the room, it will just do so at a faster rate if you leave the door open. As far as compressing an aircraft carrier to such a small size that it fit's in your pocket, well, yea but you'd BETTER have some pretty strong pockets!

johnc Posted February 8, 2010 Share Posted February 8, 2010 There are 2 identical parts, one made from alloy steel, one from titanium. Which is stronger? Pure titanium metal is actually not that strong (63ksi) and loses a lot of its strength if heated over 800F, it needs to be alloyed with other materials to get its legendary strength. So, my answer is: the alloy steel is stronger. Now if you're comparing the 6AL-4V alloy of titanium with alloy steel, I choose the titanium alloy. There's also the BetaC Ti alloy which achieves over 200ksi of strength. Quote Link to comment Share on other sites More sharing options...

You wouldn't live, you'd be a giant cancerous tumor. : Q: Why is it that all your friends seem to have more friends than you? Because you spend too much time with math.

woldson Posted February 8, 2010 Author Share Posted February 8, 2010 Because you spend too much time with math. LOLOLOL! Accoding to math a distince can always be divided in half. So one can assume that you can not pass through a door way. Really think about that one it will show you hard it is to get your self past common knowlage.

woldson Posted February 8, 2010 Author Share Posted February 8, 2010 Hydrogen! But dark matter is the most abundant "stuff" (whatever it is)... I did think of that, though I knew it had not been classified. Iron Oxide or Rust. Yep, There is just enough water vapor in the air to rust the large amount of Iron just laying around.

MAG58 Posted February 8, 2010 Share Posted February 8, 2010 What's the only currently known living organism that can produce Methane? Bacteria (at least in your guts).? Not quite. Methanogens. E. coli (the main component of gut flora) doesn't create any methane. Methanogens are acutally a group of archaea (kinda related to bacteria but not really) and they're the only known living organism that can respire to CO2 to create methane, which is actually a pretty PITA process for them, but it allows them to live in some pretty inclimate places, like garbage heaps. Not everyone has methanogens in their gut, which is why not everyone can light their farts. But please, don't light your own brand on fire to test to see if you're lucky. You'll light other things on fire. Quote Link to comment Share on other sites More sharing options...
