Does Fluoride Have A Negative Effect On Creativity?
insane_alien replied to jamiestem's topic in Speculations
unless you have a massive source of fluoride in your diet, no. (the fluoride in tap water is not a massive source) also, zero fluoride in your diet would also make you quite ill too. everything has negative effects if the dosage is wrong. -
basically instead of normal daylight savings time, they add/subtract two hours instead of one. basically, its crap for anyone north of london as the sun won't rise till about 10am. i believe the whole campaign is about stopping kids walking home from school in the dark, and it does solve that problem but it does so by making them walk TO school in the dark. its a crap idea.
-
so, first you admit you are not a scientist, then when we raise concerns about the idea, you just handwave them away effectively saying 'that doesn't matter, it just is' yeah, thats not how it works.
-
also, with your time scale, the universe has not been around long enough to spit out even two planets. and the sun definitely hasn't been here anywaher near that time
-
i think the point is that the root doesn't realise that the top has been shaved off so it doesn't switch to the growth phase. where as plucking it stimulates growth.
-
When a telogen eyebrow hair is plucked however, the growth phase is disrupted and the hair is immediately converted to anagen phase, with predictable regrowth. hmm. makes it sound like its okay to wax them off <evil grin>

mm, its worth noting that there have only been a few cases where the mathematics describing the phenomenon came before the first observation of the phenomenon. and even then, the mathematics came from describing phenomenon with some amount of similitude to the new manifestation. black holes would be a good example, we've had a basic mathematical description since newton and a good measure of the finite speed of light, although they thought of them more as dark stars than a modern black hole but none had ever been observed. we then observed black holes. the reason we could describe black holes before we seen them was because we could observe things that behaved similarly, namely massive bodies in the cosmos. we could then extrapolate as to what would happen under some unusal circumstances, then it turned out those unusual circumstances weren't so unusual.

It is a result of quantum mechanics. the wave function can exist in several energy states that do not have the energy to remove the electron from the atom. think of it like a satellite orbiting a planet, that satellite even if it is the only one, can orbit at many different altitudes. well, same for electrons although the altitudes it can orbit at are quite limited so its not a perfect analogy.
-
no its not. if nearby humans are being exposed to signaling light from the CPU when it is running then you have much bigger problems than any harmful effects of a minute quantity of UV light. really, even if you had a cpu that used gamma rays, the exposure from the cpu will be minimal and will be swamped by the natural back ground radiation. if, whenever you turned on your processor, it started shooting lightning everywhere, you'd be worried right? and it'd be broken beyond repair. well, same thing with an optical CPU, if you get a laser show its broken beyond all repair and will never work. also, the frequency of the light does not equal the processing speed of an optical cpu.
-
it has one electron, but there are many energy levels. a single atom will give off only 1 colour at any one time, but when you have a few you'll get a spectrum.

Hey, I've recently got a graphics card with CUDA capabilities, I'm wondering where i can get the applications you see people posting youtube videos of. I can't seem to find a download link to any of them. prefferably one with CFD capabilities.

Techie!!! here techie!!!! r.e. super computer
insane_alien replied to random's topic in Computer Science
1 gigahertz means the processor has 1billion (1 000 000 000) clock cycles per second. define " no waiting" there will be nothing instantaneous and even then, if its a pig of a program to load then its going to take a while no matter how fast your PC is. also, burning a DVD and watching a movie can be easily accomplished with even a cheap computer these days. -
i don't know what the capacity of a mac book pro battery is therefore i can't tell you.
-
depends entirely on the capacity of the battery. also, although one of the bus's is 12V you need slightly more than 12V to actually run the thing. 13.1V seems to be common among laptop batteries.

it protects your thyroid against I-131 which has a lot of potential to be found where nuclear fission has taken place. this is its entire purpose, its not a miracle radiation remover and nobody is claiming it as such but the method of action is real. the only place in your body iodine hangs about for any length of time is the thyroid and thyroids don't take to radiation as well as other body parts do. sure, it won't be a cure all, but it is better than nothing.
-
it does prevent radiation damage in a way. although this is with the caveat that the isotope you are being exposed to is an iodine isotope and that there is a strong possibility that you'll ingest it. it does work well at doing what it is suposed to do (saturate your thyroid with iodine to stop intake of radioactive iodine) but people see it as anti-every radiation there is. i once met someone taking potassium iodide to stop them 'absorbing tv and mobile phone radiation'.
-
bull. i can make any atom from nitrogen and up lose seven electrons. for 9 it needs to be fluorine and up. please explain the lack of a magnetic field on venus which has a very similar mass to that of earth. Really, until you stop these factual errors, not many people are going to take you very seriously.

What is the most dense material that can exist on Earth?
insane_alien replied to Lan(r)12's topic in Classical Physics
yes, i know white dwarf material is different from neutron star material. neutron star material is supported by neutron degeneracy pressure. it has already exceeded the ability of electron degeneracy pressure to hold it appart which is the force holding white dwarfs up. neutronium approaches the density of an atomic nucleus. its 10^7 times denser than a white dwarf -

insane_alien replied to Lan(r)12's topic in Classical Physics
we already covered neutron star material which is denser than a white dwarf AND explained why you couldn't really have it on earth. -
Are our tsunami warning systems good enough?
insane_alien replied to Mr Rayon's topic in Earth Science
well, the japanese tsunami struck land soon after it was created. the warning for those land masses more than 20 minutes away did get good warning about it sometimes hours in advance. the big problem is earthquake prediction. we suck at it. not because we don't invest in it, but because they are by their very nature hard to predict and any warning signals you pick up, well by the time you pick them up the earthquake is already starting. -
Predicting Earth's position in space as a result of earthquakes
insane_alien replied to Greenfaerie's topic in Earth Science
17 degrees? yeah, BS-o-meter just melted on that one. if it was 17 degrees then you currently wouldn't be alive right now as 1000mph winds would have scoured the surface of earth. earthquakes tend to affect the rotational velocity rather than the tilt and even then for a massive earthquake like this it is only going to be a matter of a few nanoseconds per day difference. this will not impact the climate -
pessimist. we have had the option to destroy ourselves entirely for 2 thirds of a century now. we haven't done it. we've came close granted but common sense has prevailed(or dumb luck) and we didn't do it. most countries with the sayonara option are getting on with each other reasonably well and the one psycho who might have nukes (kim jong il) could just be pretending, he is that crazy and if he does have them, well, they don't work very well and he won't have many. I think we're going to come round quite nicely. It'll get hairier before it gets better but we will get there. besides, with global warming and that it doesn't mean the extinction of our species, it just means we will have to seriously change our lifestyles from a practical view point. there will be more over crowding and there will be some food shortages but I have faith in science and human nature that we won't go and crap it all up beyond repair.
