  1. We can use mate to mean the same as you use buddy or pal as well. It depends what contex you use it in and how much inflection you put into it. It can also be your best friend - "he's my best mate" . Or, it can indeed mean your spouse. OK Pal! The gloves will be coming off for that one! Our language does indeed differ slightly - some phrases you use all the time in the US mean completely different things over here - I mean Phi, as a non-smoker, you would never bum a fag in the UK.
  2. :eek:The Earth is round!?! Preposterous!!!
  3. Presumably because of the v sqared in the equation for kinetic energy??
  4. Down here in the south we still use Blimey and Crikey alot - although alot of my mates use far stronger language.
  5. Well by doing so Severian, you have violated the human rights of your daughter - who are you to say she was wrong to throw shit - If she want's to throw it then she should be allowed to do so - all aver your nice white shag pile carpet if it pleases her - it is her right as a human to do as she wishes!
  6. I don't know if this is any help or not: http://www.sciencemadness.org/talk/viewthread.php?tid=10249&page=1 There is a massive thread there about various thermite variations.
  7. Perhaps you could change it from 'HornedWildebeas' to 'HornyWildebeast' thus satisfying the 15 character requirement?
  8. Good Luck to my Wife Who's PhD Viva is Next Friday. Good Luck! xxx
  9. He discovered it himself - just this week you know.
  10. I once had a meal cooked by a Nigerian man and his daughter. We had Chicken and rice with peas in it. As we got near to the end of the meal I was supprised to hear 'crunch, crunch, crunch..' coming from his direction - I looked over to see him munching away on the bones and knawing out the marrow. I told him that we don't usually do that and he said that it was his source of calcium as he thought drinking milk was disgusting - different culture. I drink alot less milk than I did as a child.
  11. Yesterday a friend of mine told me about a dream he had which he feels may be prophetic on this matter - He was in Dover (SE England) and as he looked across the channel , he saw the whole coastline of France ablaze in violent firestorms. Maybe the experiment will turn out OK after all then! Personally I think it was his subconsious doing some wishful thinking.
  12. I don't see why not - anything that creates a site for the bubbles to seed will work: broken splint, glass wool, granuals, scratches in the side of the vessel etc.. Something that I used to find useful in a particularly bumpy, small scale, distillation I used to do was to put some glass wool above the vessel at the start of the colunm - It ment that if there was a sudden big bump - the liquid would hit the glas wool 'bung' and not bump all the way over to the collection chamber - instead it would then drip back into the vessel from the wool.
  13. Try it: Substitute some numbers in for A, B, C, and D. example - A and B = 3 and C and D = 6. so we have A=B and C=D. So A/C = B/D = 3/6 = 3/6. and so on for whatever A,B,C and D are. In your case A = F, B = Tsin, C = B-W and D = Tcosx. Trig questions do get ALOT harder I am afraid!!
  14. OK - your perfectly entitled to do the following: IF: A=B and C=D Then: A/C = B/D you are dividing one equation over the other. So with: F = Tcosx (1) and B - W = Tsinx (2) you get F / (B-W) = Tcosx / Tsinx by dividing equ. (1) over equ. (2)
  15. Look at ajb's post #11. The T/T go to 1 and the sin/cos go to Tan.
  16. Any job in science needs maths. Also for any statistical study.
  17. Read the news today and apparently this year there is a bumper crop of fly agaric toadstools. The warm weather and early rains have produced some record crops of some really massive fly agarics. They look pretty - but I wouldn't even touch one - apparently you can die from even the slightest dose of these.
  18. It doesn't happen Imagine. The climers DO NOT get lighter as they climb. Except for the equation: F = G.m1.m2 / 4piE0r2 (or something like that). It means that the force experienced due to gravity is dependent upon the mass of both objects and the inverse square of the distance between them multiplied by a load of constants (distance in this case being a negligable distance as he climbs). NOTHING to do with movement, centripetal forces or electrostatics. They may apply other external forces to the body! But they will then counter gravity acording to the laws of physics, not lessen it at all. Doesn't happen. The forces acting on them from gravity are just the same - they still weigh the same and are not actually lighter in anyway at all.
  19. Since his first girl was called Sub-Unit I, and this one is going to be called Sub-Unit MkII - I reckon it's a girl!
  20. I get the same as Air (after I worked out that that Tan is Sin over Cos - not the other way round like you had it). Is that tanX = B - W/F the answer you have been given and need to prove?
  21. DrP

    Sub-Unit MkII

    Congrats YT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Sub-Unit MkII - is that like some hippy name your going to give him/her or something?? Like Frank Zappa's son and daughter are called Dwezel and Moon Unit! Was your first child called Sub-Unit I??
  22. It will be the salt in them that cures the cramps. It's a common cure for muscle cramps - I don't think many modern doctors prescribe it because of the whole "salt will kill you" knee jerk over reaction. I used to do alot of running and hard exersise - I would take alot of salt and water in my diet and I was fine. I started cutting down on salt due to peer pressure "that much salt on your chips will kill you" BS..... and I started to get some cramps during/after heavy exersise. I don't eat anywhere near the amount of salt I used to - but then I don't exersise anywhere near as much either.
  23. You can get them very cheaply - I paid about £25.00 for my one. It's about 4 inches long, made of poly styrene and is great fun. You can fly it around indoors without the fear of it hurting anyone really (as long as you dont fly it into anyones eyes).
  24. My chem is rusty, but if you look at the RHS of the equation you need to balance it, so what elements are missing? Ca, H and exess Cl. I do not how they go together on the RHS, but maybe CaH2 and Cl2? - Then you can ballance: CaCl2 + H2O + KCl > KClO3 + CaH2 + Cl2 balancing: 3CaCl2 + H2O + KCl > KClO3 + 3CaH2 + 3Cl2 I don't know if these are the right products or not, so I would feel happier if someone like Hermantrude or YT would varify what the products should actually be. I mean, you night get CaCl2 and H2 - I don't know.
  25. That sounds about right - The gross mass being the mass of the container and substance. The net mass being the mass of just the substance. Presumably you work out the density by dividing your net mass over the volume of the liquid in the cylinder.
