Does it have number.toPrecision() like javascript? Cheers, Ryan Jones

Yes and I very much doubt it would be from a supplier that they could easily be traced from. Lets face it ban or not people who wan to do damage will. Buy lots of Asprin oer a long time and no-one would suspect a thing why ruin others hobbies when they could be trying to find these people instead? Cheers, Ryan Jones

Well, it makes sence... something collapses smaller and smaller untill there is no known force that can hold back the collapse. This was a long debate, a good book to read on it is called Black Holes and Time Warps. When a star is in mid life its forces are ballanced, gravity trying to crush it and its internal reactions trying to make it explode are equal. To the end of its life the stars starts to run out of fule and so its internal force is decreased. As this occurs the gravity overpowers it and compresses it. Assuming the star does not expode this will form a neutron star, the electrons were forced into the protons making neutrons. This can only happen within a limit, if the star is bigger the a limit (of which I forget the name) then the repulsive force of these neutrons is no longer strong enough to hold of the collapse, the star shrinks past the Schwarzschild radius forming an event horizon, then into a singularity. One of the funny things is that as the star crosses the Schwarzschild radius it will appear to freeze, thus their former names, frozen stars. Even though if you were on the surface of the star you would see it progress as normal but thats a relativity effect. Cheers, Ryan Jones

OOO, nice. Looks like a fractal version of an image I saw called the known universe - thats pretty neat. Cheers, Ryan Jones

Well, [ce]NI3[/ce] can be set off by loud sounds but it is highly unstable. for more reactions the effect of normal sound waves is neglegable at best - its better to simply use heat. Cheers, Ryan Jones

CRAP! So it does, an it looks like its comming this way... I feel unwell. TW, you've probably guessed - I like Stargate http://zyzstar.kosoru.com/projects/fractals/images/fractal-04.jpeg That one is just amazing, I can't even think what it looks like though... Loks like some sort of malformed galazy being pulled into a black hole... Anyone else have any images, prize for the most interesting / wierd fractal Cheers, Ryan Jones

Could beone of the main causes of evolution. Given high doses though the damage is to much to replair and the cell dies or in some cases we get an ever replicting cell, a cancer. Funny, a possible cause for random evolution and yet it kills too. If youwant tosee what radiation can do look up Hiroshima... here are some photos that show how nasty it is. Cheers, Ryan Jones

I've also noticed that sometimes there are posts about news in the science forum its self, e.g. sometimes physics news in the physics section. Should there not be a way to have these moved to the news forum etc. Maybe requests thread? Cheers, Ryan Jones

I don't know - I think it looks like the instant just after the big bang... also, reminds me of the idea of the quantum foam... Next up... To me tht does looks like a big bang... it even looks like there are some other universes forming in there too Cheers, Ryan Jones

7? Souds good to me - looks like a nice mix of stuff Anyone else have anything to add? Cheers, Ryan Jones

Red spots, sounds like Jupiter has acne... Unfortunatly the sky have been unleashing snow here so I have been unable to check it out for mysel. Cheers, Ryan Jones

Thats true, lets face it you would not be a resident expert if you did not know your stuff. We should just leave that one out. Other then that it seems like a good round selection of choices Cheers, Ryan Jones

I have one comment, when we vote we should specify which field the mod belongs too... if not we should have a best overall knowledge section instead... would be more fair I think Cheers, Ryan Jones

Heres a new one just of the net: What do you think this one looks like? Cheers, Ryan Jones

True, very true... I can think of a few uses for them but as Dave said they seem to be more of a mathematical curiosity... Cheers, Ryan Jones

Well, its a common missconception. For example if you replaced the sun with a blach hole of equal mass it would not pull in the planets because its still the smae mass. It is not knows wether or not black holes actually exist but there have been experiments that have found evidence of gravitational lensing, an effect that is thought to be caused by a black holes extreme gravity where the light is bent towards the event horison. Black holes are potentially very interesting and a lot of developments in their theories have been madfe in the last few years by people like Stephen Hawking who for example has proven that black holes can evaporate through what is called Hawking radiation. Black holes themselves are basially a star that has collapsed beond a boundary called the event horison. This is the point at which the gravity of the star has such an effect that going beond that means you simply cannjot escape due to the way space and time are distorted. At the heart of a black hole is a point called a singularity, this is the point at which time and space no longer exist - its a point of infinate density and infinate smallness, its also the point at which our current understanding breaks down. If you want to do research I really suggest you look at Wikipedia, it has a page full of interesting facts that may help you. http://en.wikipedia.org/wiki/Black_holes Also, of additional interest: http://en.wikipedia.org/wiki/Worm_holes http://en.wikipedia.org/wiki/Neutron_star http://en.wikipedia.org/wiki/White_hole Cheers, Ryan Jones

I guess that makes sence because fractals have a large surface area... You could makea really big antena with a HUGE suface area Cheers, Ryan Jones

Thats certainly an interesting use, I'd think fractals could be used in encrption too because of their essentially random natue. Anyone agree with that? Cheers, Ryan Jones

Sounds interesting... Never heared that one before. Cheers, Ryan Jones

I see Arn't fractals chaeotic systems? If they rethen that would explain their applications in some areas such liquid dynamics as you stated above Cheers, Ryan Jones

Fractals - any real uses? I love fractals, the question is are they useful for anything? I knowthey preduct certain shapes in nature but do they have real uses or are they just pretty patterns? Cheers, Ryan Jones

Sounds like soome nice round cats there, looks good Cheers, Ryan Jones
