    And yes, heat has mass. But not very much.

    There are 3 doors. 1 has a prize behind. You pick one. Then 1 of the other doors is opened to show that a prize is NOT behind it.

    You then know the prize is either behind your door, or the other unopened one.

    You are then offered the chance to switch doors? What should you do?
    Switch.

    Gives you 50/50 chance of winning. Sticking gives you 1/3.

    Always switch. It's because the person who chooses which door to open after you made your choice has more information than you.
    yeah, stats friend explained it to me, but it still feels like it defies logic ;-P

    Why switch?
    Only difference is that your odds went from 1 in 3 to 1 in 2.

    If you can read this you really need to fiddle with your forum settings.

    If you stick your odds are still 1/3. They didn't change. They only change if you switch.

    It's a famous questions anyway, call the Monty Hall Problem if I recall. Worth googling to get your head around it.

    Basically, when you pick 2 times out of 3 you'll pick an empty box to start with. The host removing one of the empty boxes leaves an empty and a full, which means your odds increase if you switch. Now shut up.

    If a duck's quack doesn't echo, does that mean you can be picked out of a line up of real ducks because your quack does echo?

    LB, you really are a massive geek.

    Duck's quacks do echo.

    If a fly hits a windscreen of a truck that's full of birds that are flying around inside a sealed container on a treadmill, does it take off on Mars?

    Gremmi has been stealing ducks from his pond and making them quack in his basement. Don't ask how.

    If you pick your answer randomly from the options below, what is your chance of being correct?

    * 25%
    * 50%
    * 60%

    No wait! Let me think...

    Um... My brain hurts. I think that there is no right answer, but I am trying to figure out why I think that.

    It's unsolveable. It would be 25%, except when you choose 25% (when it becomes 50%).

    50% of the time, it works 25% of the time.

    Four cats have catbells on their collars.

    Catbell A
    Catbell B
    Catbell C
    Catbell D

    How many catbells should you remove?

    Sorry phAge :)

    Of course, it has to be the same amount.
    So no energy can leave or enter the spacesuit. Therefore mass inside the suit will stay the same but it might change form i.e. live human to dead human.
    Although it did baffle scientists for some time (I'm not sure if it still does) that the human body loses a very small amount of weight at the point of death. Some have hypothesized that this is the weight of "life" or the "soul".

    The world is going mad. Me? I'm doing fine.

    Am I heavier with a lungful of air than I am without? Eh? Eh?

    We could have a new diet craze here. Want to lose weight? Stop breathing.

    @RyanDS Surely it is still 50/50 as there is one right and one wrong door. It doesn't matter in this case about information level as whether you switch or not the odds are still 1 in 2.

    Just like how the odds of heads and tails are 50/50 even if you've had 100 heads in a row.
