  1. Haha.. I hope you know that I posted this question more than 4 years ago, when I was still in school. (...and looking back at it now, my typing was absolutely HORRIBLE!)
  2. Hey Kaytie11 I'm personally a night person myself. I hate waking up early in the morning (but I hardly have a choice because of lectures ). I usually stay up till around 3-4 AM which is when I go to bed. I know some people (my mom, for example) who just can't stay up as late as I can. It's a natural 'body-clock' thing where the body decides (and in some cases) wants to go to sleep. As for your age, I suggest you get plenty of sleep. As YT said previously, you're growing up, and you need the sleep. Once you're older, you'll automatically find out what kind of person you are (be it a night person, or a morning person). Oh yeah... and keep away from smoking, energy drinks, soft drinks, and sources of caffeine... you don't need them
  3. I believe Hoffman degradations also reduce carbon chains, but I believe you need to have amide groups in.
  4. Thanks John! Would you happen to know the mechanism for the decarboxylation?
  5. Hey YT! I've been busy at university. I'm double majoring in Chemical Engineering and Chemistry and doing a minor in Math... so, I have a lot less free time than I had The conversion to Benzoic acid makes sense, but I'm not exactly sure how the redcution would work. You could use a variety of substances for the reduction (Sodium Borohydride, or Lithium Aluminium Hydirde would also work). But as I see it, you'd compeltely reduce the benzoic acid to Benzyl (or phenyl) methanol, instead of removing the carbon group from it. Unless I've gotten the mechanism completely wrong...
  6. Hey guys! I'm wondering whether or not it is possible to be able to eliminate the methyl group from toluene by using a relatively low amount of energy/reagents. I am well aware that this reaction is not favourable. The overall reaction I'm looking for would be: Methyl Benzene ->Benzene + CH4 (I'm guessing the other H would be obtained from solution) I'm considering the probability that the reaction may be impossible due to the fact that you'll need to have a CH3 leaving group. I'm also thinking that a Hoffman degradation wouldn't work because you need to use Amines? Thanks
  7. Are you referring to Lenz's Law? If so, consider this: Does this mean that every magnet can only generate a certain amount of current, ragardless of the strength? If that is the case, then it makes sense that a stronger magnet generates more current because you are applying a bigger force, and hence, the conditions are not satisfied. I hope I explained myself properly?
  8. Hmmm... didn't realise that! Does that mean that the force required for moving a magnet across a wire is dependant on the strength of the magnetic field? Is there an equation that would allow you to work out the force required? One more thing.... does this mean that the amount of current induced in the wire is contsant, only it is the force that makes the difference? Thanks a lot for your time
  9. Okay, let me try and explain what I meant: Take it that you want to induce a current in a wire, let's say to power a very tiny bulb. You are given two magnets, a strong one and a weak one. Which magnet would you choose to make the bulb light up the most? Most obviously the strong one, as for the same motion, you produce a geater current and hence a greater amount of electrical energy. Does this make sense? Or am I talking a whole load of rubbish?
  10. Hi guys! I am pretty sure I am going to regret it, but I'll ask anyway! Let's say, you have two magnetics. One is an NIB (rare earth magnet, really powerful) and one is a fridge magnet (vey weak). Now, you also have a fixed lenth of wire connected to an ammeter/voltmeter. If you run each of the magnets down the wire, at the same speed, the rare earth magnet produces a greater current, we all know that. Consider this: Your kinetic energy is being changed by the magnetic field into kinetic energy. This means that the NIB magnet is has a greater efficiency. Please correct me if I am wrong in any of the statements above, but, what exactly is going on here? Does this mean that you could get a magnet that is 99.9% efficient? Thanks for your time guys.
  11. Thanks for that. I didn't check the ISBN number. I'll just make sure on that before I place the order. Thanks alot for that guys!
  12. And a sixth one called a Fermionic Condensate http://en.wikipedia.org/wiki/Fermionic_condensate
  13. Thanks alot for your help guys. I'll try and get the Fabric of the Cosmos first, before the other books. Thanks alot for your time!
  14. I think I know an average amount of the string theory, because I already watched the series, which talks about the string theory in breif. I know for sure that I wouldn't even dare to try and read the book without some background knowledge on the string theory. Thanks alot for that tip though!
  15. Thanks alot for the links RyanJ. the only problem is that at the moment, I would only like to try out one of the books before I move on to the other one. Any suggestions?
  16. Hi Guys! I was interested in buying the Elegant Universe by Brian Greene, so, I searched on Amazon, and two titles came up: *The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory *The Elegant Universe Also note that BOTH of the book are by Brian Greene. I am interested in learning about the String theory, multiple dimensions etc. and have watched the NOVA release of this. I am just wondering, which one is the book that I am looking for? Thanks alot guys!
  17. I think he may need with understanding some of the science. I think we'll just wait for him to come back.
  18. About the books....that is the problem. BOTH of the books are by Brian Greene! And both seem related to what I want. Which one is it?
  19. Hehe.. although not an answer to my question: Relativity deals with massive objects, and its equations work fine with it Quantum physics deals with extremely tiny particles, like atoms and subatomic particles. They start to falll apart when dealing with objects like black holes. Which one should scientists use? Relativity because a black hole is extremely massive, or quantum physics, because the black hole is extremely small? Whichever one is used, the values that come out is non-sensical, and that is where they collapse.
  20. Which book of the elegant universe do you recommend? I did a search on Amazon, and two books came up: *The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory *The Elegant Universe
  21. Yeah, which is why I gave to 'safe' experiments. How did me manage to steal the potassium? With gloves?
  22. Hmmmm.... its the 'other dimension' that I don't really agree with. We are able to use 4 dimension, and are all contained in a dimension so large, that it could contain parallel universe. What I think that you meant to say is that you have gone to another universe or brane. If that is the case, then yes, the string theory states that it would be impossible to send signals using the technilogy that we use today. This is because the string theory, now th M theory states that there are two types of strings. One with open ends, and these are tied down to the brane we are one, and ones with closed ends, like a circle, and these are able to escape from one universe to another, ie from one brane to another. They think that this string is what makes up the graviton, and therefore, this is why the force of gravity is weaker then all the other forces, as some of it leaks out to other branes. So, what could all this mean? It is possible that it would mean that we could be able to communicate with other universes on different branes by exchanging 'graviton waves' or something to that extent. And yeah, who can really say? Its all a theory that I don't think will be proved for a veeery long time
