  1. Ive never had any experiments go wrong for me.....luck or skill (most prob luck) and i do a resonable amount of toying considering.

    The worst thing ive seen happen is a chick in my chem class was doing a copper content in brass titration and a guy shoved past her knocking over a flask of conc nitric acid, gave her a few scares and no shoes:p

  3. yu're refferring to the dark matter question, yes its possible that gravity might be interacting with our universe and causing some of these effects, prob is at the moment we have no easy way to detect it. Thats the reason gravity is "supposidly" so weak is because it can leave our universes dimension and travel into higher dimensions, which is the interaction of gravity you're talking about...... if string theory is correct

  5. I think' date=' first, we need a working definition of the word "drugs". One of the best I've seen is: "A Drug is any non-food substance that affects body function."

    [/font']

     

    The best definition i seen is "Any substance that is taken and has no nutritional value at all" Your definition of saying "any non-food substance" seems wrong...there are many drugs that are foods

     

    BTW i know several old drug addicts quite alot of whom say it just feels like they are tripping permanetley all the time, is this due to what the drugs done to their body or is it because they probably have excess still left in their system? Does any one ever full recover from the affects drugs have? or does it depend on the drug?

  6. Prove the triangle inequaltiy as follows

    a) [ math ]|z_{1} + z_{2}|^{2} = |z_{1}|^{2} + |z_{2}|^{2} + (z_{1}Z_{2} + z_{2}Z_{1})[ /math ]

    (b) [ math ]z_{1}Z_{2} + z_{2}Z_{1} = 2Re (z_{1}Z_{2})[ /math ]

    [ math ]<2|z_{1}Z_{2}|\[ /math ]

    [ math ]=2 |z_{1}][z_{2}|\[ /math ]

     

    Where capital Z's are the conjugate,

    Oh and < means greater than or equal to

     

    Cheers

  7. We know the radius because we can measure it indirectly (bond lengths) and through share theortisising, it works. we can see atoms with special microscopes (electron microscope) but cannot see it with visible light for obvious reasons. I have seeen several pictures of atoms, but theyre not much to look at really

  8. I heard someone at a youth conference say "god may have just set things in motion so it looked like there was a big bang".

     

    For evidence just look at what god was like and turned into....like he allowed in-breeding when he first created the world ("go forth an multiply" to adam and eve, how were they to do this without in breeding) there are heaps of contradictions i have found in the bible you just have to look for them....but basically there will always be people on either side of the fence...just more people on the right (evolution :) ) side..

     

    BTW Go.Sorcerer .....another kiwi in the mix...YE-YAA

  9. In the explanation of the Principle (Feynman Lectures) where i read it stated, "the path in which the first order of time is not altered but the second order of time is"

     

    I dont get that part, cheers for the help pangloss

  10. Soz if i got the dudes name wrong, I was wondering if any body knows of any good books/sites or has any good interpretations themselves into the principle of least time/most time?

    I dont get what it means when "there is no change in the first order time, just a change in the second order time???

    Im finding this principle very hard to pick up and would appreciate the help.
