  1. Unless they don't. https://en.wikipedia.org/wiki/Human_multitasking#Sex_differences
  2. IQ is only a measure of how well you do in IQ tests.
  3. Part of "creation" (whether it be created by a God, the big bang or the spaghetti monster) is mankind; and mankind does that sort of thing. So the mouse with an ear on its back is a part of creation. Preventing that sort of thing would be "tampering with creation" just as much as allowing it would be. So what was your point?
  4. Perhaps i should expand slightly on that. Since Lenz's law follows from Newton's laws of motion and the conservation of energy, you are not going to break it. Anything designed to defy it will fail.
  5. This might help https://en.wikipedia.org/wiki/Sleep_paralysis On the whole it's not considered a pleasant experience.
  6. "A motor design to defy lenz law" will fail.
  7. Who gets to decide what is necessary?
  8. I doubt that. https://en.wikipedia.org/wiki/Impact_depth#Newton.27s_approximation_for_the_impact_depth
  9. Do other languages have the equivalent of this? I take it you already know of tough and bough and cough and dough? Others may stumble, but not you on hiccough, thorough, slough and through. Well done! And now you wish, perhaps, To learn of less familiar traps? Beware of heard, a dreadful word That looks like beard and sounds like bird. And dead; it's said like bed, not bead. For goodness sake, don't call it deed! Watch out for meat and great and threat, (They rhyme with suite and straight and debt) A moth is not a moth in mother, Nor both in bother, broth in brother. And here is not a match for there, Nor dear and fear for bear and pear, And then there's dose and rose and lose -- Just look them up -- and goose and choose, And cork and work and card and ward And font and front and word and sword. And do and go and thwart and cart -- Come, come, I've hardly made a start. A dreadful language? Man alive, I mastered it when I was five.
  10. You were told of two. Incidentally, do you realise how cheap diodes are?
  11. On a weight for weight basis the sun produces roughly as much heat as a compost heap. This is jut as well. if it was ten times faster the Sun would be have pretty much gone out before we evolved. (Well, we would have had to evolve on a planet in orbit round a smaller star)
  12. I have an idea. Either you have the knowledge to know if it's right or not, or you don't. At the moment you lack that knowledge. Because I have not yet explained what my idea is. Whose fault is that?
  13. So, if my school timetable had put my chemistry lesson on Monday and my physics lesson on Tuesday, the gas laws would be chemistry, but, if they put the physics first then the same laws would be physics. Well, I guess it's a point of view... However the gas laws are unequivocally part of chemistry (whether they are part of physics or not). Incidentally you need to find out the difference between taught and learned. That's especially ironic, given your "name". Incidentally, have you noticed that none of this has a lot to do with the OP's question?
  14. If you had to learn it a second time, you didn't learn it the first time. So to say I learned it in chemistry tells you that I learned it in Chemistry. I may well have subsequently been reminded of it lots of other things. Monsieur Clapeyron was roughly two hundred years late, since Boyle discovered (at least part of) it in 1662 and Jaques Charles drafted his law in the 1780s
  15. Would it still be a dream? Incidentally, the answer to the question that forms the title of the tread is almost certainly yes. For example I'm sure that Kylie Minogue has been in a lot of peoples' dreams.
  16. This is worryingly close to medical advice from a bunch of people who aren't qualified *but... If you plan to add something to a person's blood stream, you should generally make sure it's isotonic. https://en.wikipedia.org/wiki/Cytolysis Whetehr you do that woith salt, sugar or something else depends on circumstances. * one of the important qualifications is knowing the details of the patient
  17. It's perfectly possible for a clean surface of a metal to look nearly black. A stack of razor blades can be used as a light absorber. https://books.google.co.uk/books?id=fdhGGY4Xw_QC&pg=PA216&lpg=PA216&dq=razor+blade+light+trap&source=bl&ots=ixfj6aKDHd&sig=nPvE3hPOyQzO8pNKMv60yjiDeSU&hl=en&sa=X&ved=0ahUKEwjy95bt-KzMAhUKM8AKHdecB_MQ6AEIIjAB#v=onepage&q=razor%20blade%20light%20trap&f=false
  18. Wissen 85, Since you don't appear able to find it without help from a grown up, this is what scientific research looks like http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3685533/ Granted, that it it only 1 smallish study, it shows the exact opposite of what you claim.
  19. If, as Wissen seems to have done, you redefine "albino" to mean "not black as the ace of spades" then then the opening premise is true- at least in part. Otherwise, it's not. When I said this "OK, lets just check on something. By any conventional definition, I'm white. My ancestors are, at least for a few generations, almost entirely Scottish. (and, as it happens, my parents married in South Africa so a stupid legal system that was snotty about such things "declares" that I'm white). So, according to you I am an albino. However I have brown eyes and dark brown hair; I tan if I go out in the sun. So, according to any conventional definition, I am not an albino. So, you are- at least by conventional use of the word "albino", wrong. Are you saying that everyone else doesn't know what the word means?" Your reply was But, as I pointed out, I have dark brown hair- not red, and I tan in the sun. So that clip from wiki is irrelevane. Please answer my original question.
  20. It is far from clear what your "current model" is. " Basically, I'm building a basic generator from scratch." have fun, but if you want something that works well either buy one (which I accept is no fun at all) or find a good book on motor design. "Although, something else that may be reverent...do you happen to know if there's some kind of materiel that can increase the inductance of the coil" Yes, that's why most motors transformers and generators etc have "iron" cores with winding round them. That's what the iron is for. (and it's more likely to be relevant than reverent)
  21. News to me; I learned it in chemistry. I'm not the only one. http://chemwiki.ucdavis.edu/Core/Physical_Chemistry/Physical_Properties_of_Matter/States_of_Matter/Gases/Gas_Laws/The_Ideal_Gas_Law and I suspect that the people who use it are more likely to be chemists and chemical engineers than physicists. At the time when it was discovered I'm not sure that the words "chemistry" and "physics " were in common use. https://en.wikipedia.org/wiki/Boyle%27s_law I'm reminded of this http://xkcd.com/435/ It hardly matters because the issue is one of the history of science; there isn't a "history of science" section, so it's bound to be in the wrong place.
  22. The big problem with "storing" acetone is that it's a small, fairly polar, molecule and will diffuse rapidly through cells. It would be difficult to stop the stuff leaving the "gland" and being dissipated in the bloodstream.
  23. OK, lets just check on something. By any conventional definition, I'm white. My ancestors are, at least for a few generations, almost entirely Scottish. (and, as it happens, my parents married in South Africa so a stupid legal system that was snotty about such things "declares" that I'm white). So, according to you I am an albino.

  24. Indeed, so why did you introduce it?
