Other Sciences

hello! im new so dont be to tough on me i want to fill ballons up with hydrogen and oxygen (because its easier) and ive modified a 1.5 litre coke bottle so that 2 carbon rods are sticking into it. then all i have to do is add water and an electrolyte and hook it up to some electricity and put a balloon on the mouth. but this takes a ridiculous amounts of time to even fill the balloon up (not even till its standing up) so my question is, if i hook up the rods to the wall outlet via an old cord, will this speed it up alot? enough to fill a balloon within half an hour? ive tried adding more electrolytes (mainly NaCl) but it hasnt made much of a difference at al…

I think the EPA should be charged with labeling products that are “green” in nature vs. ones that just sell on such a title. I would even go as far as to think it would only help consumer habits if say some green product for sale had a sticker on it. This would imply certain standards to the definition that I think could be handled by scientists. I also do not think it would be to difficult to coordinate also.

My general idea is simple! Is it not possible that Intelligent design, that is the creation of life by intelligent means ( I have no idea what it is or could be, the possibilities are endless and mind boggling ) could incorporate evolutionary process. In other words life was created and meant to evolve and form on its own. While i already understand that intelligent design theory has not been able to produce lab results, I also know that mathematics is a very real thing, and Intelligent Design theory definitly has the mathmatical evidence. I also know that Evolution leaves behind some very real evidence, and i believe it happens every day. Science today has …

I've got a Coke Zero here in front of me (I don't actually, but I did when I first thought of this question and its a good demonstration). Supposedly this contains zero calories. I suppose that means I could drink an infinite number of these things and never get fat. How on earth could that be? If you took some Splenda and burnt it will it really not raise a milliliter of water a single degree? How could this work and how can they say it?

Hello. Q1. How far and fast can a neutrino travel? Q2. How do we know if neutrinos come from our sun, when neutrinos can pass through all known matter? Could they be coming from another star instead? cheers.

A sclerochronologist (!?) on how crossing the Atlantic gave him an insight in geological time.

I saw millions of ladybugs today that obviously mass-hatched. They were all headed somewhere, although none seemed to land on anything. Does anyone know how long these hatchings last? Is it hours or days?

So my physics teacher was telling us about a climatologist who is predicted a tipping point in the whole global warming fiasco within the next decade. Apparently some studies showed much LESS CO2 in the air than what should be there based on our emissions. Upon investigation, it was found that a large quantity of it was being dissolved into the ocean. His theory is based on the simple characteristics of gas solubility in liquid. It is known that cooler solvent can dissolve more gaseous solute. As such, he predicted a time when the rise in temperature will cause the ocean to be able to dissolve less and less of our emitted CO2 and reach a point of saturation when the ocean…

Skylab was America's first space station and orbital science and engineering laboratory. Jon Cowart is a great host with a millionaire mustache. Enjoy, MC

I want to learn more about the sciences of PV and thinfilm solar panels, can anyone point me in the direction of a good book on the subject (or webiste)? Such as how they are made and how they actually harness energy. Also, if anyone knows where to read more about wind energy, it would be greatly appreciated.

To elas I am puzzled. Could you please explain why you think what I said is 'on dangerous ground?'

It's a Friday night, and my girlfriend has to work in the morning so didn't come over. I'm decompressing after a long week. School has been challenging, but we did take our last oral quiz today in Chinese, and all that is left is our skit show and final. I've got a solid A in the class, so reimbursment from my company will arrive in a few weeks. That is of more importance than one can know... So, it's floodin' down in Texas tonight. I've been watching the radar for the past few hours, embedded as picture-in-picture as I catch up on my recorded shows while the GF is not here. Monster storm coming in. Tornadic activity, huge down-pours of rain... But, that's Tex…

Hi, everyone. One day I've seen some kind of (photo?)filming, when camera captures the movements of gas. I mean, the viewer can see, how gas expands and so on. Does someone know the name of this kind of filming? Maybe you can give me some links to articles or videos? ) I'll be very thankful, thanks in advance. p/s. Sorry for my ban English, I'm from Kazakhstan

I am trying to work out what cumalative frequency is. My son is doing a test on 250ml of water running out of a hole in a beaker into a measuring jug. The times per 50ml are 14,33 50 78 180 seconds. He has been told to show them in cumulative frequency ???? any ideas I'd be very grateful Ian:confused:

The Space Shuttle Minute is NASA's wrap-up of activities surrounding Space Shuttle processing at NASA's Kennedy Space Center in Florida.

i was just wondering, is there a slight chance that sound can be the sixth phase. we all know that the phases are solid, liquid, gas, then plasma, but yeah i'm just wondering if there is a chance....

I was talking to my housemate and he raised a point I wasn't certain of how to explain, about how Earth's atmosphere was transparent. I mentioned about how the particles in gases were so widely dispersed compared to other particles, and he mentioned that other gases can block light... So I commented that eyes must have evolved to take advantage of nitrogen's transparency to what we term "visible light" when he reminded me that oxygen and carbon dioxide are transparent to those same frequencies too. So how do I respond to the fact that nitrogen, oxygen and carbon dioxide all being transparent to the same wavelength frequencies of the EM spectrum when other gase…

1:00 am. Tired. Too much MatLab. Too much genetics. Need a good laugh. Solution; a free visit to M. Behe's website, Mr. Irreductible complexity. Very funny. First of all, unlike most scientists, Behe doesn't feel the need to use visually appealing graphics. Nooooooooooooooooo. But, he got a mousetrap. I could not believe this, I mean, this guy must sit on more $$$$ than most evolutionary theorists (of course, the source is different). Right after that, there's the "the Lehigh university is ashamed of my ideas but for some reason hasn't fired me yet" disclaimer. Which is also quite unusual. But hey, when you're a révolutionaire... And at…

Apparently there is some tension in the philosophy of science between Kuhn a Popper, as I've deduced largely from discussions here. I can't say I know much about either of them. I've got Structure of Scientific Revolutions but I haven't read it yet, and I've never come across anything of Popper's. I think I'll Wiki it and education myself a bit better. But in any event, I was curious, to which philosopher do you subscribe? Is this just a false dichotomy? How many other important camps am I missing? Respond away.

I have a Hypothesis, that to ME makes perfect sense, let me begin by assuming we all now WHY and HOW a hot-air balloon works and rises in our atmosphere. now with that established, couldn`t some sort of solid structure be made from light alloys such as Beryllium types, and then have a vacuum created inside it sufficient that the air molecules removed it greater in mass than the structural mass + load, and then let Free, it should Also Rise shouldn`t it? I personally can`t see any reason why in principal it shouldn`t work, maybe I`v missed something?

Hey all, There is an ample amount of metaphor being used in the forum threads, which is not a problem, I think there is a problem when you try to use the title of a theory, say, paired with something that has nothing to do with the original theory in order to get a point across. For example: "...whilst the evolution of history is...." since this is a scientific community, it is ambiguous whether the author is trying to use structure of evolution to describe the events in history or if history itself has genetic code and 'survival of the fittest' is an accurate method to describe how history survives. As you can see this is a simple case and most people can see right t…

Can any one tell me what will be the scenario taking place when high-energy proton beams come in contact with the brass material ?

Nice, broad topic here. Where do you draw the line and say "this is a science" and "this isn't"? I suppose at one extreme you could say that anything that ends in "science" or "-ology" qualifies, on the other you could take a Rutherfordian position and say that physics is the only science and all else is stamp collecting. So what is science? The easy answer is "any study that applies scientific methods," but in respects about every field does to certain degrees of emphasis. Historians will formulate hypotheses and test these from the historical record with various degrees of "scientific" robusticity, but does that make history a science? Or, if you want to go…

The Vain Technology. Empty fruits of advance Can science and engineering/technology really ease our life or only new troubles can appear as a result of development of it? Why new technologies have been being applied in industry and labour productivity has been increasing for more than century, but people have to work so much as in the past? Why workday isn't being reduced anywhere, but instead of it people are making and selling more and more things which were needless before? Why at work I shall can earn more money in same work time (may be), but I shall not can work less for same money? History of first sewing-machines invented in England may help to find answe…
