You Say Potato (Posted on 2003-06-04) Difficulty: 2 of 5
Let’s suppose that potatoes (by weight) are 99% water and 1%, well, potato!
If we take a 100 pound bag of potatoes out and put them in the hot June sun, the water will begin to evaporate. If we monitor the moisture content (which starts at 99%, of course) and we weigh the potatoes just when the moisture content gets to 98% (precisely), then how much will the potatoes weigh at that moment?

How much will they weigh when the moisture content is 50%?

Genetics and percentages | Comment 6 of 8 |
Have you ever heard that chimps and man are 97% the same genetically? Or that no man is more than 99.7 percent different than any other man, genetically speaking? This bothers me, not because of the genetics, but because of the math. How many instructions are there per genome? Billions, trillions, right? I mean I'm not a geneticist, but that's what I hear. So if we are 97 % the same, then we are 300,000,000+ instructions different than all of them. I'd really like to get a number on this, because if it's in the low billions, then there is someone genetically exactly like you somewhere in the world of 6.3 billion people, heck more than one even. You do the math.
