## Logic Only a Geek Would Understand or Use

I am not sure of my own position relative to this week's resource. It is quite unusual and I am recommending its underlying idea more than the book itself.

Garth Sundem's Geek Logik: 50 Foolproof Equations for Everyday Life claims to use the power of algebraic equations to answer life's questions regarding dating, romance, relationships, careers, finance, health, and more.

Designed to be humorous, the book actually is the result of a college-prank of sorts. Yet, it actually contributes to the science of decision-making by identifying key variables and their potential influence.

For example, suppose the question is: "Should you get a dog, cat, or goldfish (or should you stick with houseplants)?" And the associated equation is:

[(M+N)SQRT(D)+HR]/[8T2] = Fido where

D = Need for more love in your life (1-10)
R = Your general level of responsibility (1-10)
T = In any of the past six months, what is the largest number of days you spent traveling?
H = In hours, your extra time per day
M = Your tolerance for another creature's mischief (1-10)
N = How nuturing are you? (1-10...with 1 being "my cactus died")

If Fido<1, sea monkeys would be too ambitious, if 1 < Fido < 2, get a goldfish, of 2 < Fido < 3, get a cat, and if Fido > 3, get a dog.

By substituting various values for variables in the above equation, students could see if the expected relationships hold. Also, by playing with the equation, students could determine which variables dominate or have the biggest impact.

Though you would not be able to use most of these equations in a mathematics classroom, you would be able to have students determine their own decision-situations and then create a representative equation with key variables. It could be both fun and entertaining.
