Doctordick Posted March 16, 2006 Report Posted March 16, 2006 It is now 400,000km off course and slowing down at a rate of less than 100 millionths of a centimeter per second.Sorry but you have got something wrong there as "slowing down at a rate" is a rate of change of speed (acceleration) and "100 millionths of a centimeter per second" is a speed so the sentence doesn't make any sense. :eek2: If you think you are quoteing a speed, you don't tell us how long it takes for it to slow down that much; a second, a minute, an hour, a day, a month ... . Essentially, as stated, what you are saying is that every second it slows down 100 millionths of a centimeter. That is like saying my car slows down three feet when I hit the brake. :) Have fun -- Dick Quote
Jay-qu Posted March 16, 2006 Report Posted March 16, 2006 people blind from an early age (or even born blind) can hear much better than sighted people because their brain recruits help from their inactive visual cortex! Quote
DFINITLYDISTRUBD Posted March 16, 2006 Report Posted March 16, 2006 It is said that if you know six people then you know indirectly everyone else on the planet!:eek2: Quote
Jay-qu Posted March 16, 2006 Report Posted March 16, 2006 Tardigrades are the toughest creatures on the planet!From Wikipedia: 1. Tardigrades can survive being heated for a few minutes to 151 °C or being chilled for days at -272.8 °C (almost absolute zero). 2. Radiation— Shown by Raul M. May from the University of Paris, Tardigrades can withstand 5700 grays of x-ray radiation. (Five grays would be fatal to a human). 3. Pressure—They can withstand the extremely low pressure of a vacuum and also very high pressures, many times greater than atmospheric pressure. In theory, they could even survive the vacuum of space, though the possibility of it is slim. Hardy little things:) Quote
Qfwfq Posted March 16, 2006 Report Posted March 16, 2006 What you quote from Wiki refers to the state of cryptobiosis. Quote
Jay-qu Posted March 16, 2006 Report Posted March 16, 2006 does it.. I actually got it from another site that quoted wiki.. If all the overweight people in the world where to loose their fat than they would release approx. 10 billion tonnes of carbon dioxide into the atmosphere. Quote

GAHD Posted March 16, 2006 Report Posted March 16, 2006 ...In 1943, UC officially takes over operation of the government laboratory at Los Alamos, N.M., that is continuing the work of Berkeley faculty and others in the development of the atomic bomb...I withdrawoh well it was a cool idea anyways. I'd have loved to be able to tell My ex that her brother was getting irradiated while he was there...:eek2: there are 2 main types of circulatory system, Open and closed Open has no diferentiation between blood and interstitial fluid. Closed has a distinct seperation between the blood and the rest of the body's fluids, relying on a series of arteries and veigns for transport. Open is also usually copper-based and about 1/3 as efficient as closed which is usually iron-based. Quote
Boerseun Posted March 16, 2006 Author Report Posted March 16, 2006 ...the two systems, of course, being easily discernable by the colour of the blood! Iron based - (most animals) blood is red when oxidized.Copper based - (molluscs, etc) blood is dark blue when oxidized! Research is currently underway to use pig's blood (only the colourless plasma part of it) together with plant-based clorophyl for carrying oxygen for emergency blood transfusions. So pretty soon, is someone at work cuts his finger and bleeds green, you'll know he was in hospital recently! Will do wonders for anemics, although they will look a bit off-colour... Quote

Racoon Posted March 16, 2006 Report Posted March 16, 2006 Lightspeed in an ideal vaccum = 299,792.5 km/s !! :eek2: :eek2: Quote
DFINITLYDISTRUBD Posted March 17, 2006 Report Posted March 17, 2006 Seriously...pray tell...HTF do they know this?!?..how do they figure out things like this?!? Lightspeed in an ideal vaccum = 299,792.5 km/s !! Quote
Qfwfq Posted March 17, 2006 Report Posted March 17, 2006 Seriously...pray tell...HTF do they know this?!?..how do they figure out things like this?!?Actually, the speed of light in an ideal vacuum is exactly, precisely equal to 1. Quote
Boerseun Posted March 17, 2006 Author Report Posted March 17, 2006 Through embriology, it became clear that our lungs developed from aquatic air-bladders! Human foetuses first develop the circulatory equipment for gills (actually having the proper gill-slits as well) before the air bladder develop to assume the breathing role. In other words, aquatic animals first had to learn how to swim upright and control their buoyancy before land animals could breath! Fishy... Quote
Racoon Posted March 17, 2006 Report Posted March 17, 2006 1 Rad (rd - Radiation Dose) = 0.01 J of energy absorbed per kg. 1 Joule (J) = the work of 1 newton through a distance of 1 meter. 1 Newton (N) = force that will accelerate 1 kg mass at 1m/sec^2 quarky, Quote
