Walk or Run in the Rain

For a couple years I have wondered about whether you get wetter by walking or running in the rain. I know the Mythbusters have attacked this question, but don't remember their conclusion. I decided to try to tackle the problem mathematically, and while I made some assumptions, I think my conclusion makes sense.

Classifying Quadrilaterals

Julie was working on how to classify quadrilaterals for her class, so I made up this chart that kind of breaks it down. I thought it turned out pretty good, and it gave me a chance to use my Kevin font. The one thing I didn't include was kites which have two sets of congruent sides that are adjacent to one another.

Big Numbers

Most people don't know a lot of large numbers. I myself do not know a lot of large numbers, but I know more than most people, and I am going to share some with anyone who wants to read about them. Most people know thousands, then millions, and billions. A large number of people probably even know that after billions comes trillions. But what comes next? Is it Gazillions? Bazillions? Nope, quadrillions. Here is the breakdown...not all of them, but enough to sound smart.

1,000,000,000 (1 x 10^9) One Trillion

1,000,000,000,000 (1 x 10^12) One Quadrillion

1,000,000,000,000,000 (1 x 10^15) One Quintillion

1,000,000,000,000,000,000 (1 x 10^18) One Sextillion

1,000,000,000,000,000,000,000 (1 x 10^21) One Septillion

1 x 10^24 One Octillion

1 x 10^27 One Nonillion

1 x 10^30 One Decillion

1 x 10^99 One duotrigintillion

1 x 10^100 (a 1 followed by 100 zeroes) Commonly called a googol (not google) it could also be called ten duotrigintillion.

1 x 10^(10^100) would be a googolplex. That would be a 1 followed by a googol of zeroes.
