Just think about you jumping up then falling down, then you running and jumping and falling down while flying forwards. Going forwards doesn't give you any bonus upwards acceleration or velocity, it's weird for me to imagine it being any other way, how would going forwards stop you from going down?DrRockor said:I took A level physics for a year and I just didn't understand most of the stuff we were told. One of the worst ones was that if you fired a bullet from a gun and dropped another identical bullet they would hit the ground at the sametime. It's all about velocity and gravity but it just doesnt sit right in my head
When people say 'look' at particles they don't mean when we see them with our eyes, in fact, we can't see sub atomic particles with our eyes, it's nothing to do with the detection side, it's that we have to physically do something to the particles to detect them, thus breaking down their wave function and giving them a defined area in which they could be in, not multipleThe-Epicly-Named-Man said:
How about the publishers who put it on the shelves in the first place. They're the ones I blame personally.Talshere said:Someone looked at he Twilight books and though "they will make GREAT movies", followed immediately by, "Twilight actually did make really successful movies"
Haha, this made me think of one:Avalanche91 said:There are still people argueing for creationism in 2012?
There are people who think europe and africa are countries?

Well, it's just their skin that is black. Their fur is "clear" (as in see through) and quite thick so that it makes them look whiteCrazy_Dude said:
the greeks did not discover pluto it was Clyde Tombaugh in 1930 and the name was from a girl who had an interest in mythoglage, her father worked with the telescope the was used to discover itScarim Coral said:I was going to say the whole "we eat spiders a few times a year when we are asleep" but I pretty sure that is not concrete true fact.
So I guess I go with Pluto is in fact a planet! I just feel that denining it's a planet at all, it's a like a big screw you to the Greek who discover it in the first place and Hades himself.
Pretty sure the satelites' time doesn't quite speed up. They are only fast in RELATION to us. Time for the satelite continues on at exactly a steady pace in the same manner it does for us. It is all about the relative relation between mass, time and position.Popadoo said:They don't lose time, the clocks actually SPEED UP when orbiting the Earth. Yeah, their high speeds will make their clocks slow down too, but the effect gravity has on time is much greater than the effect speed has on time.Talshere said:It could be so hard to believe because general relativity isnt true. At least certain aspects you have to use special relativity to get a sensible answer. If we ever get one theory that actually works for everything it may well be a whole lot easier to understnad.Popadoo said:When I was first taught about general relativity I found it hard to believe. I mean, come on, simply by being in low-gravity you age faster and time just general moves quicker?
But it's true, as it turns out. They have to reset the ATOMIC CLOCKS (super accurate clocks) on satellites every day, lest GPS be miles and miles off.
Also, the actually US GPS system, I dont know about GLONASS, GNSS or future Galileo, Compass or IRNSS systems, but I suspect they are the same, you don't actually alter the clock on the satellites (I misspelt this as satalites and auto correct has suggest to me Australites, Natality, Satanism and Satanist.....Go go autocorrect...) they check them individually against known location ground station and then work out the time error based on the error in position, the satalite then as part of the ping it sends out of its position says "I have an error of this" which the handheld devices then compensate for.
Also, I'm fairly sure the standard theory for the loss of time is due to the speed they are travelling relative to the earth is that much greater and the closer you get to the speed of light the slower you age (Though this could just be the special theory of relativity). The actual loss of time per day for satellites is negligible but it does become significant over time. For one day however the inaccuracies generated by the bending of the signal path as it travels through the atmosphere is significantly greater. Compensating for this bending is one of the biggest problems in satellite navigation as the difference it can make is huge.
When they first developed satellites they didn't believe simply being high up, away from stronger gravitational pull, would effect them. Within MINUTES the satellite was so far off GPS would mark you miles from your position. Granted, it's literally hundredth of a millisecond difference, but when you're trying to triangulate say, a phone out of anywhere on the whole EARTH, it makes the difference.
And thus, we have another victim who had a Bridget dropped on him. So, to help avoid such occurances again i have made up the following.Yggdraz0r said:
