Math Makes Pizza Better

So the other day, I made one of the dumbest decisions of my life. My wife and I are at a pizzeria, and I notice the price of a 8" pizza is 1/2 the price of a 14" pizza. I brilliantly suggest we get two 8" pizzas because we'll get more for our money. Why is this not true?

Math Review
Remember that the area of a circle is πr(squared)


The area of the 8" pizza is:
π x 4(squared)
π x 16
16π
50.24
The area of the 14" pizza is:
π x 7.5(squared)
π x 56.25
56.25π
176.625

So the 8" pizza is 50.24 square inches of food
and the 14" pizza is 176.625 square inches of food.
The 14" gives you three and a half times as much food!

Hopefully you won't make the same mistake I did.

Weightlifting: Not Just for Meatheads

I've been pumping iron since the New Year to improve my life in the fitness department––and it's working. Amazingly, I've gained thirteen pounds of pure muscle, boosting the measure of my gravitational force to 168 Earth pounds (179 on Saturn).

The great thing about being male and thirty is that I am old enough to gain weight and young enough to see rapid body changes. I may not ever be a bona fide beefcake, but I am getting stronger and practicing discipline. There are other concomitant benefits.

I am breaking through the description my father gave of me during college, "You have the body of an academic." It was true, and I have to make some progress now before the black hole of of school swallows my free time next fall.

Speaking of Adonises, two of Saturn's moons are Titan and Atlas. Follow these links (link1 and link2) this to see some of the most beautiful images you have ever seen. How can something be so beautiful? What makes it so? There is something ineffable amongst the colors and shapes that captivates my imagination. The photos were taken just weeks ago!
