I was just watching a movie called "What the Bleep do we Know?", and in it, they explain that the double slit produces an interference pattern, when they are performed normally. However, when we try to measure the position of the electrons, instead of an interference pattern, we just get two bands, corresponding to two slits. They further state that measurement by a conscious mind leads to this phenomenon.
Is this true? If yes, where can I know more about it? Is it the measurement that causes the interference pattern to change into two bands? Why is this so?

It's base is 780.5 miles in length, and the other sides are 836.25 miles and 669 miles in length. It's height is 1226.5 miles...

Is it possible to determine square miles from these numbers? If so, how many square miles in the triangle?

I was worried about having low iron or protein so I have been taking 2 multli-vitamin Flintstone's vitamins, 2 chocolate Calcium vitamins, and a Joint Juice can everyday. (contains Glucosamine)

Anyways, I was reading on a few doctors "what to do before surgery" and it said to avoid taking vitamins up to a month before the surgery because they can thin your blood! Should I stop?

I want to be really healthy before going in there, but I don't want to bleed all over the place either. Anyone know? I don't see my doctor for three more weeks and that is for the one week pre-op.
