How does gravity follow the law of energy conservation? Just wondering... don`t hit me

The greeks had a competition for women where they danced and showed off their bods and this competition was called the Callipygean Games Kalos is beautiful and Pyge is buttocks so Callipygous means "has nice buns" or graceful ass or whatever, you figure it out. Linguistics is a science. why doesnt this board have a forum where Linguistics belongs. And etymology (word origins). maybe it does. maybe "General Science" is the right place for linguistics-related stuff

Is it possible to have a peltier device that was around 5-15*C on the hot side and maybe just below 0*C on the cold side? If yes, what size would it be, and how much power would I require?

Glass, is it a liquid or solid. You always hear that glass is always melting, and when you look at old works of glass, you notice the bottom is thicker then the top. Its really not defined either way. I searched it on google.com, but no define answer for it.

Can global warming be attributed to the large increases in processes in today's world that produce heat. Every day things such as transporation, A/C, creation of electricity, all produce heat. Can this be linked to global warming?

Hey, if you have the money, why not shoot your body into space when you die.. along with lots of other bodies? this way, your body is very well preserved, and has a 1 in 4 chance of aliens finding your body and making you alive again! (1 in 4 chance part was meant as a joke) so, you would either be found one day by something.. or end up burning in a star =), hmm.. what you think lol

Does a physist have no knowledge about chemistry? Does a biologist have no knowledge on the chemistry? What's the basic of science? Observation, hypothesis? Or a smart brain>?

I didn't know where I should ask this so I just did it here. My book that I am reading on Light & Sound Waves states the following. "Consider what happens when waves of sound move through the billions upon billions of particles that make up the air. A disturbance -- the ringing of a bell, a revolver shot, a mewoing of a cat -- causes the particles of the air nearest the disturbance (call them A particles) to bump into there neighbors, which we shall call B particles bump into the adjacent C particles and so on. The series of collisions brings about variations in pressure of the air; the variations are transmitted through the air at the rate of roughly a mile …

Most of you have probably seen the commercial for the Laser Straight. It is a wall-mountable laser that projects a line across the wall for haning objects. Of course, it is only accurate as you are in placing it on the wall. The part I do not understand about the commercial is when they show it with the laser line going around the corner onto a perpendicular wall. The narrator also acknowledges that, "Laser Straight even goes around corners!" However, I cannot understand how this would at all be possible unless mirrors were involved--and even if they were, a mirror would turn the line into a dot projected onto the adjacent wall, You can see Laser Straight …

Interesting picture on the Astronomy Picture of the Day today: Sure makes you wonder about the ol' albedo, doesn't it?

This invention called the nero net is the accumulation of a year of thought and research. Many problems I have solved but many more unforeseen problems will most likely occur with something as advanced as this. The basic Idea is to hook up an EMG, TENS and AMS system. And synchronize them to send receive and intercept electrical signals form the spinal cord with no invasive surgery. This would create the holy grail of virtual reality. The EMG is used for receiving signals. The EMG today has problems with differentiating muscle signals from one another. The problem is that the EMG has no depth making all signals run into one another. Creating one large signal ins…

JUst a bit of fun, maybe sparking a big discussion. IM me for the answers, also I will post them up in a few days. 1) The static charge you feel after walking around in Woolworths for a while and touching a meatle object is around 10,000V. 2) The Colour of Water is Blue. 3) Earth Has two moons. 4) In 800 Years there is an 80% chance that asteroid 1950 DA will strike earth. 5) Bug is the slang word for beatle. 6)The 3rd Biggest conspiracy (rated by channel 5) in the world is that Adolf Hitler is alive and living at the south pole making UFOs. 7) Polythene was invented in Northwich, Cheshire, UK 8) It uses more energy to fly to New York (from…

I have sometimes experienced that sometimes, when I close my eyes and am thinking about something or repeating(visualizing) some memories in my mind and get totally absorbed in thoughts ,and all of the sudden if someone bang the door, or make some other loud sound, immediately at the same moment ,on my mind screen something like flash or lines similar to the lines on the TV screen (when not receiving picture ) appear upon my mind screen for a second or lesser time. I want to know if somebody else have the similar experience, and can explain the scientific reason? mab

Global Warming is Good For You! From the Houston Press Above all, Gerald T. Westbrook is a man concerned with truth. For hours he works at his computer in the small office of his Memorial-area home, writing his latest scholarly paper or drawing up a lecture. He's the kind of guy who writes everything out in lists, and packs boxes with files of news clippings and interesting tidbits he's come across in his research. His cane, needed after a knee injury, and hair as white as paper add to the professorial image. He insists he's a firm believer in the scientific method, and a strong proponent for making sure research is dictated by facts, not personal agendas. West…

basically, as the title suggests im a little bored, what can i do to keep myself busy? home made experiments? i've got some strong magnets, which im making the repel each other, which gets quite boring after a while!!! i have general house hold items, can get hold of electronics, dont have many chemicals readily and/or locally available sadly.... any ideas?

LINK VANCOUVER, Washington (CNN) -- A series of unusual earthquakes near Mount St. Helens in recent days has scientists warning that something more serious could be imminent.

In Science, Do we deal with uncertainty only when the numbers we get are from the measuring we take? or there is other situation where we need to deal with uncertainty, in which has a limit of accuracy? Albert

Is a solid state civilization feasable in the long run ? Humans evolve until they learn to modify their own minds, their mental circuits, their emotional circuits, the way information is organized. Then minds will be hooked up to computers and virtual realities and then trillions of solid state neurons, minds, computers will keep on evolving continously until it is completely uncomprehensible. A Solid state civilization. We observe according to the way our mind is organized and organizes information so what and how we observe and our theories and interactions with reality are quite arbitrary. In the future when we start to modify the ci…

If pressure dictates boiling temperature what is the boiling temperature of water in a vacuum? 0*c?

Hey, I'll be in an upcoming school debate over wether video games decrease literacy rates or not. Does anyone here have a degree in psycology, or any other applicable science? If so, can I have your opinion? (Dont get me wrong, I've got nothing against video games.)

Im sick of this, I've seen it spelled two ways in two articles recently.... Which is it!!!!!!!! I originally started spelling it as Occam, untill I read it as Ockham in a New Sceintist article...... then I assumed I must be spelling it wrong all this time and started spelling it that way.... now I read an article where its spelled Occam! Argh!

Hello there I once read some information about the use of lacquer in strengthening light-weight materials, specifically the leather armours once used during the Samurai age in Japan. This process allowed for leather to be strengthened to make it as strong as steel...yet maintaining the much lighter form of armour that was prefered in Japan rather than the much heavier external equivilants. My question would be - How could you strengthen Cardboard to make it rock solid, Waterproof and Durable? but most importantly - Lightweight? Thanks for reading Noel Belfast N.Ireland

Is a man more dangerous swimming in pool(floating) or staying on ground(touch land) when there is lightning? Will the situation change when it is sea water?

I'm currently working on my final design project at uni - designing a wearable cooling device for very humid conditions (e.g crowded rock concert), which would be worn on the wrist. I'm proposing to use an umbilical system, which means (from what I ..umm.. researched) that i need a reservoir, pump, cooling device, heat sink, power source... From what I understand, the temperature of the device needs to be kept above the dew point to minimise condensation. My challenge is to somehow fit all that inside a wrist band/cuff and to use a motor (Wellington Motors - they are special) somewhere in the device. The other option that I have is using a series of inbuilt Sunon mini-fa…

Don't laugh, I know how hard it's supposed to be to do this. Wanted to know if anyone had any ideas other than "haha you idiot mars is easier." Because frankly, I've been doing the math and it strikes me that Mars is not easier, and will in fact take much longer, and its biosphere would be much more fragile. My hope is that the idea will intrigue someone who may want to help with the math as a bizarre hobby :3 That’s not to say I haven’t done a lot of math already >_< *brain pain. The Goal: Transform the Atmosphere The Venusian highlands shine in the radio spectrum because of high compositions of pyrite (iron sulfide, FeS2). These two massive continents…
