Simple question, but why is the sky blue but we still get loads of white light coming through the atmosphere and we don't all appear blue. Moreover, if the sky is a brilliant blue and the sea reflects the colour, why is the sea sometimes green? All simple answers welcomed.

Is it possible that religion is causing psychoses ? Is it possible that the same is doing philosophy ? Is it possible that religion is one big false and philosophy contains only nonsenses ? lately appeared new theory which is connecting religion and philosophy with mental illness, it is describing in text "Religion and philosophy as illness": " (the author of the text originates from outside of Anglosaxon lingual area) ... 1. All domain of esoterism, of yoga, of meditation can be counted to the area of primeval religion. It is the same what shamanistic beliefs and practices. 2. These practices consist in the obtainment of the state of trance, …

Yes. Theories are interpretations of experimental/observational evidence. The experiment can't be wrong, but the interpretation can. That is why theories are never proven.

This is thermite- http://www.yikers.com/video_thermite_destroys_all.html But is this termite?- http://video.google.com/videoplay?docid=-2991254740145858863&q=cameraplanet+9%2F11"]Video Is that thermite? Now notice the fire above it. It isn't bright hot like that. And if that was an electrical fire wouldn't the sparks fizzle out immediately?

Many people think that the terms human race and human species are interchangeable. I don't agree with that - aren't races subsets of species? Are races the same as strains? Saying that, how many human races are there and what are they called? Is caucasian a race? asian? african-american?

I am trying to make a ferrofluid display cell with 1oz plastic bottles and water. The water will not mix with the ferrofluid (its oil base) but when a strong magnet is brought close the ferrofluid flows to the edge and coats the plastic so when the ferrofluid is no longer there the plastic is still black. I have had some amount of success with mixing soap with the water but that still doesn’t last long. A thicker solution of soap and water also helps but that minimizes the length of the spikes. Any ideas? Edit: You can see a display cell at: https://www.teachersource.com/catalog/index.html You must do a search for "Ferrofluid Preform Display Cell" T…

I would hope that this may be an appropriate Forum for consideration of a Cross-Disciplinary Theory. Having published a summary of my research into the Theory of a Human Response to Tectonic Stress there was very little response from the Geoscientific Community. This may be because work has only recently developed on the interactions between the lithosphere and the biosphere. This is not a 'pure' Geological theory and neither does it fit comfortably in the Humanities. Can I urge this Forum to consider the possibility that the effects of tectonic stress may influence human behaviour. A summary of my research can be found on the Geological Society of London's website a…

Say you're framing an hypothesis for an experiment. Should you phrase the hypothesis so that it's a positive statement even if you personally expect to see a negative result? For Example: "If I throw a lemur it will fly." I would expect for a lemur not to fly if I were to throw it, but should I phrase the hypothesis positively anyway for when it is to be tested?

Freeman Dyson is the last of the greatest 20th century physicists, a colleague of Einstein and Feynman, Professor Emeritus of Princeton’s Institute for Advanced Study, who wrote Imagined Worlds which has a chapter on ETHICS that documents the facts about why scientists have failed Humanity for over 50 years. Some of the more important quotes that characterize scientific culture are: The most historic warning of all is reserved for the UC National Labs, the worst case example of tenured welfare state scientific culture devoid of humanitarian motivation characterized by Dyson, is contained in President Dwight D. Eisenhower’s 1961 Farewell Address to the Nation: It …

Why do dogs bark at things we cant see? I know most of you don't believe in invisible manifestations of deceased living things, so whats the explanation though. Really the reason i started this thread was to just ask about the dog thing (my dog was just barking at one when i took her outside to pee), but while i'm at it i'll ask some ghost questions. Of coarse theres plenty of discovery channel specials on electromagnetism found in haunted houses, and light orbs that only appear on special cameras and such--- what do you think about it? The dogs see something--- animals are the first to detect earthquakes and similar phenomenon (even before seismographs?), maybe its not g…

i was thinking about 'spontaneous human combustion' today and i was just wondering, though i'm not trying to prove it or anything, if a human body was to reach a high enough starting temperature, would it burn unaided, even if the source of heat stopped?

MANCHESTER, England (Reuters) - Mysteriously snuffed out candles, weird sensations and shivers down the spine may not be due to the presence of ghosts in haunted houses but to very low frequency sound that is inaudible to humans. http://asia.reuters.com/newsArticle.jhtml?type=scienceNews&storyID=3401200

Why do we use soaps on our hands and bodies. I've always just used soap to wash my hands like all of us have. But what exactly does soap do to remove germs and bacteria and odors, etc. that plain water doesnt? Can somebody explain how soap works to me. Im a simple minded man haha. I know soap removes oils from your body/hands but how does it help remove germs and bacteria?

I've used a 'break barrel single action air rifle' type gun once before but never really thought about how they work. Now I am! Here is a link to what I mean: http://www.bbguns.co.uk/843_1_1054906.html Basically you break the barrel, put it back and the pressurised air is loaded. This is an air rifle (not spring) so what I want to know is how the break/unbreak action causes the gun to fill with pressurised air??? Also what is the opposite of breaking the rifle/barrel??? (unbreak the rifle?)

Hopefully you will experience the good ghosts and not the bad ghosts . Also , I don't know why this thread is in religion , when it could just as much be at home in theoretical physics .

Yes, it's time to bring up discussion on something alchemists have tried to do for many millennia. So, how did gold get here in the Universe and on Earth? What's your big idea?

Perhaps the atomic bombs on hiroshima and nagasaki were not dropped by american jets but were fallen from alien sky portals!? So much of the world has changed after world war 2? Are we living in a developing world or a rehabilitation world?

I was at the park, when a man from the water company drove in. He began using an orange instrument which looked like those metal detectors I've seen people using. It had a box with a meter on top, only instead of a flat pickup plate at the bottom, it didn't have anything. It just ended with a cap. My friend began talking with him and we found out he was looking for a metal cover that was buried. The instrument was beeping at different rates as he passed this "wand" over the ground but he became frustrated when he couldn't find it. As we watched, he got another instrument that was similar (but yellow) and looked more like a cane without a box on top. It didn't do any…

what i wanted to tell is, scientific community should ask questions instead of defending evolution, such as why only biblical creationist should be taught in schools why not islamic or hindu? amerika is a secular country every theory then should be taught. such questions should be asked, by the way i am from india and we have no creationists here, not a single and in our schools we have evolution every year! and no one here challenges evolution, in our syllabus evolution is cumpolsary, if you dont read it you lose the marks :D well back to point this is what i got from http://www.icr.org/index.php?module=articles&action=view&ID=1842 ==========================…

Calculating the viscosity of a blended liquid consisting of two or more liquids having different viscosities is a three step procedure. The first step involves calculation of the Viscosity Blending Index (VBI) of each component of the blend using the following equation (known as a Refutas equation): (1) VBI = 14.534 × ln[ln(v + 0.8)] + 10.975 where v is the viscosity in centistokes and ln is the natural logarithm (Loge). The second step involves using this blending equation: (2) VBIBlend = [wA × VBIA] + [wB × VBIB] + ... + [wX × VBIX] where w is the weight fraction (i.e., % ÷ 100) of each component of the blend. In using the above blending equation, it…

Here`s the idea, I want ALL who read this, to think of the individual nubers !, 2, 3, 4, 5, and 6 for next Saturdays lottery in the UK at 8:50 pm is the draw I`m going to put those numbers on my ticket, I want you all to WILL them to appear, bear with me, I know it sounds a bit screwball! an experiment was done in a TV studio some years back, they were given (the audience) a set of numbers to WILL for the appearance of, it worked at 87% (well above probability!) I wish to test this for myself, and want some volunteers/helpers. IF we DO win the big one (jackpot) all will have an equal share of the money, this money will only goto the serious ones! email me on satur…

Hello everybody and everyone! I'd like to share some thoughts about sound perception here. ========== First, does the phase of the harmonics matter in a periodic sound? This was a debated question when Hi-Fi was fashionable, and is still interesting. Here's a piece of software I made for more general purposes. It creates a file Tut.wav playable by Winamp, Windows' Sndrec32.exe, Media Player and probably more. The user defines a spectrum (hence of a periodic sound), the soft writes the sound in the file. TutD.zip I recommend to listen with headphones rather than PC loudspeakers that create misleading distortion even at low level. And this…

I always put a spoonful of honey on my breakfast porridge. (Granulated sugar tastes nicer, but honey is better for health, supposedly). The thing is, where does all the honey come from. I buy my honey in a jar, from a local supermarket, and its shelves always have masses of jars stacked on them. When you think of how many supermarkets there are in the world, and how many jars of honey they have on their shelves, how much honey does that represent - a million tons? Could that massive amount really all come from bees - wouldn't there have to be so many bees, to produce it, that there'd be huge bee-farms all over the place? But has anyone ever seen them? The …

WE SHOULD NOT TACKLE THE ENERGY PROBLEM BECAUSE IT IS EASY. WE SHOULD TACKLE IT BECAUSE IT IS HARD. President John F. Kennedy said something similar about man's going to the moon.
