    Sure we only need to look at the Sun to see it orbits the earth.

    Alas we will never see the underside of this earth disc we live on :(

    It's not?

    gravity is a force of attraction in nature between 2 objects the force of attraction is proportional the the mass and the square root of the distance between them i think

    It will indeed, thanks for pointing it out. :)

    Ah, Science.

    Well a kettle of it would scald slightly. ;)

    Oh I see what you mean. No, not really, that's Science, constantly refining itself. It's actually a pleasure to be corrected for a change. Thank you. :)

    Yes, you have it right more or less. I remember it from LC Physics.

    The Law of Universal Gravitation states that any two point masses in the Universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

    The constant used in the direct/inverse relationship is the Universal Gravitational Constant.

    I've seen it.

    It says "Made in Japan" on it.

    Water is blue.
    I see blue as red though.
    So it's red.

    It's blue when it gets deeper as this is light condensed. Red is the first colour to leave the spectrum.

    Just a bit of LC physics.

    Increase in electromagnetic wavelength = redder colour
    Decrease in electromagnetic wavelenth =blue-er colour

    One reason why Physics is so enjoyable to learn. It can be applied in real life. :rolleyes:

    Ah, that is the term. Ok.

    ...


    What physics doesn't explain is why you came to use the :rolleyes: smiley in your post, unless it was unintended sarcasm :pac:

    That smiley can be used when one wishes to express extreme exhaustion and is no longer aware of what he/she is typing anymore. :p Good night sir. :)

    PS- I too love diving! :D
    Last spot was down Hook Head.
    ANYWAY, good night.

    I thought you had with a name like Science Nerd :)

    I studied Optics for 5 years at collage. It's rare that I find a thread in AH that I can relate to !

    Watch more QI. Fry says all kinds of quite interesting stuff- like the colour of pure water being a very slight blue but this isn't observable in small quantities, like your puny glass or dirty tumbler.

    Stephen Fry wouldn't lie. :D

    Drunk in the pub the other night we ended up debating about the colour of water( I know what you're thinking, "calm down you crazy bastards") and even ended up putting a 10 euro bet on it.

    so while im waiting on my email response from stephen fry

    do you think water is blue or clear?



    also whats the most ridiculous thing you have got into a debate in a pub about?

    So what colour is water at night-time?
    FFS!

    Got into a debate with a lad about perpetual motion... his idea was to put an electric generator at the foot of a waterfall (so far, so good) but he then thought you could use the generator to pump the water back up to the top of the waterfall where it would then flow over the precipice and onto the generators thus continuing ad infinitum...

    poor lad couldn't figure out what was wrong with his idea!


    Pumping the water back up would take more energy than the generator's could produce, that and one of the laws of thermodynamics say its impossible
