    Half the size and mass, stronger force of gravity?

    I am pretty sure that the new r is not r/2, but something greater than that (although less than the original r). The decrease in M is much greater than the decrease in r. Meaning that gravity will decrease.

    Automotive Why don't we see more I6s being produced?

    True, but I would think that for 6 cylinder applications, the straight six would be preferred. It would necessitate a slightly (around a foot or less) longer engine bay, but in all other areas, a straight 6 is superior to a V6 (I think, am i wrong?).

    Automotive Why don't we see more I6s being produced?

    It has perfect primary and secondary balance, has a smooth power delivery, and can be very fuel efficient. So why do we see so many V6s? Except for BMW and the Cummins diesel, I can't think of another I6 produced today. Back at the dawn of the automotive industry, they were very popular. What...

    Upstate NY Man Finds Flammable Water from Gas Drilling

    I just read a news article about a man in upstate NY who claims that gas drilling near his home caused gas to leak into his water supply and out of his faucet. He demonstrated this by holding a lighter near his faucet, which causes sparks to flame up. Now, I took chemistry, and know how a...

    Planck's blackbody radiation law is proved untrue at nanoscale distances

    A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists had never been able to confirm, or measure, this breakdown in practice. For the first...

    There is no such thing as Nuclear Waste

    What do you guys think of this editorial? It was published about a month ago. It claims that almost all spent nuclear fuel is reprocessable and what is not can be either used for something, or safely stored until we could find some other use for it. And the only reason why we don't reprocess...

    Why do living beings die?

    If cells can always reproduce and replace themselves then why do living beings die? Living beings die due to the cumulative effects of years of free radical damage to the cells of the body.

    Nuclear batteries

    If they figure out how to manufacture them efficiently, we might see nuclear powered batteries in a few years. It seems from this article that engineers were finally able to convert radioactive decay into a useful form of power...

    Thermoacustic freezer

    A freezer was recently invented for Ben and Jerry's by researchers at Penn State called the thermoacustic freezer. It freezes with sound waves. Ben and Jerrys likes this because it is more enviromentally friendly than regular refrigeration, since regular refrigeration gives of...

    Is Too Much Vitamin C Bad for You?

    Linus Pauling was, according to many, the greatest chemist ever. He discovered most of what is written in chemistry textbooks today. He won 2 Nobel Prizes, one in Chemistry, and the other in Peace. Towards the end of his life he declared Vitamin C a cure-all, and started chugging down obscene...

    Physics, Chemistry, Biology?

    As a current pre med student, I can tell you that medical schools don't care what your major is. You can major in sports history, art, or any other non science major and still get in. However, you do have to have a high total GPA and a high math and science GPA. However, almost every med...

    Derivative of fraction without quotient rule

    The following problem appears in my textbook (before it discusses the quotient or product rule, so those rules cannot be used for the answer): Find the derivative of the function: \frac{x^3-3x^2+4}{x^2} I brought the denominator to the top and multiplied it out to get {x-3+4x^-2}[/ltex]...

    Sterling hybrid car, will it work?

    Is this "thermoelectric generator" a sterling engine? If there are no other engines that are powered by heat, obviously it must be a sterling. But is this so?

    Sterling hybrid car, will it work?

    What do you all think about the following idea? A hybrid car could be built using a regular internal combustion engine, with a few small sterling engines connected to a battery resting on top of it. The car will start running on the internal combustion engine, and as it is running the heat...

    Cellular membrane question

    i learned in my cellular biology class today that hydrophillic molecules don't diffuse through the membrane easily, since the inside of the membrane is hydrophobic. my question is that water easily diffuses through the cell membrane, and water isn't just hydrophillic, it is hydro! so why can...

    Adding organelles to a cell.

    what would happen if you took out the nuclei of many animal cells and injected into them the nuclei of identical plant cells, and put these cells together. i know that they will all grow cell walls, but will their walls fuse together in the test like they do in regular plants?

    News Pros and Cons of Abortion

    when sperm meets an egg, if nothing else is done, the now fertilized egg will usually implant itself into the walls of a uterous, start dividing into more and more cells, and eventually develop into a living person. for me, that this is enough for it to be called living, the same way a child is...
