The Summinator
9 January 2007: Graph Theory
[Said in Deep Voice] The Summinator.
I left the other doodles in there just because I thought they were kinda cool. That, and I hope that whenever I look at "The Summinator" I get a brief reminder of the cyclic and transitive graphs.

Grid

This is just a grid, but it's actually made out of the characters between 2551 and 256C in the character map (Times New Roman). See ╬║╝╔╚ ╗╦ ╣╩ . They just all happen to fit nicely when arranged properly.

I don't remember exactly how the relationship goes, but I remember how we, as a class, decided that this illustration represented the Minimal Vertex Separator For A Complete Graph

This is an illustration of my professor. He was wearing black slacks, a blue shirt, and sandals with flaming socks that day. And these are the actual graphs that he was drawing on the board as well.

Bipartite Hand
10 March 2007:
First day of spring break, 2007. It was nice to take a few minutes to sit and doodle to relieve the stress of the semester thus far. There's a hand hidden in there.

Poisson Distribution
Stats 3000: Sometime Fall 2006.
The poisson distribution is a distribution in Statistics, but poisson is actually french for "fish". These are my two fish. The big guy is an 8-10" Oscar, and the little guy is a 3-4" Green Terror.
The Poisson Distribution (quoted from my stats book itself here) is; "A random variable X distributed as a Poisson random variable with parameter λ, which is written X ~ P(λ) and has a probability mass function P(X=x) = (e^-λ * λ^x) / x! for x = 0,1,2,3.... The Poisson distribution is often useful to model the number of times that a certain event occurs per unit of time, distance, or volume, and it has a mean and variance both equal to the parameter λ."

Binary Search Tree
CS 5050: Advanced Algorithms
January 2007
We had to draw a Binary Search Tree of height=7. I thought "I Can't Fit That Onto A Piece of Paper Neatly.... I Need A Bigger Canvas....Hrm..."
I drew this on the sidewalk on campus, took digital photos of it, and then turned those photos for my homework. Dr. Yan Really liked it. :-)
Theorem: Let T be a (proper) binary tree with n nodes, and let h denote the height of T. Then T has the following properties:
1. The number of external nodes in T is at least h+1 and at most 2^h .
2. The number of internal nodes in T is at leasat h and at most 2^h - 1.
3. The total number of nodes in T is at leasat 2h + 1 and at most 2^(h+1).
4. The height of T is at least log(n+1)-1 and at most (n-1)/2, that is, log(n+1)-1 < h <(n-1)/2.
That Means that this binary tree has

LockedOut
Linear Algebra, 8 Oct 06 Right before class, I managed to accidentally put an unknown password on my laptop....so I couldn't take notes on my machine during linear algebra as I usually do. I was forced to use archaic pen and paper! Anyway, this is how I felt during class - I was quite frustrated. However, when I got home, I was quite sure to make haste and figure out a way to hack the windows password, which I sucessfully did and got back into my windows machine. Oh, and in this copy, the blurry parts are where I photoshoped' out the *naughty* words.
Rocket
Statistics 3000, 10 October 06 I like to doodle rockets and stuff blowing up.....if you haven't already noticed, it's a recurring theme in my doodles.
Sleepy
Linear Algebra, 11 October 2006 I was really sleepy in class today, so I had to doodle some to stay awake. But all we went over was the inverse of a matrix, which is pretty simple, so I didn't miss anything big.
