About Me

    Hi. Welcome to Kode360.com

    My name is Ken Rumsey, otherwise known as Koding. I am a college student currently in my 2nd year of study working towards an AA in Mathematics and an AS in Computer Analysis/Programming. I should complete both degrees in the Fall of 2008. In Spring 2009, I intend to start my undergraduate studies to get a BS in Mathematics and and then on to a PhD in Mathematics.
    I 1-sin(theta) Math!!

    The site will contain a seemingly random assortment of things as I am interested in many things. One day I could be talking about a 360 game, then a math problem I'm working on, and end the day with a post about an anime I recently watched. There's really no way to predict what I'll blog about

    Thanks for reading. Enjoy.

Have you ever done one of those things, usually a stupid thing, and you look back and you say to yourself “what was I thinking!”? I did one of those today.

I had just gotten out of work and was driving home. I was coming up on an intersection and heard a siren. Looking down the street, I saw a very large fire truck, lights and siren and all that, weaving through traffic coming to the same intersection. So I started slowing down. When I realized the fire truck and I were going to get to the intersection and roughly the same time, and I not knowing which way he was going to turn, I slowed to a stop before the intersection. As everyone knows you’re supposed to.

Everyone but the moron in the car behind me.

He starts laying on the horn and tries to drive into my trunk. I guess he figured if I wouldn’t move, he’d push me through the intersection. Note, at no time did he actually hit my car. The fire truck entered the intersection and after he did, I pulled forward and started moving. The moron decides to play “let’s see how close I can get to your bumper” and rides me to the next intersection.

We get to the next intersection and the light turns red just as I get to it. This is where the “what was I thinking?” comes in. I don’t like to be tailgated. I don’t like someone blowing their horn at me when I’m in the right. Before I knew what I was doing, I had put my car in park, gotten out, and walked back to the guys car (who was still behind me at the light). His window was already down and I proceeded to explain to him what a moron he was in using his horn instead of his eyes to see *why* I wasn’t moving, and then to draft me all the way to the next corner because he had been held up for 10 seconds or so.

He could see I wasn’t happy (I guess it was pretty obvious) and waved his hand out the window as to dismiss me. Having delivered my message, I went back to my car and drove off when the light turned green. He stayed a fair distance behind me before turning a corner a few intersections later.

After all this happened, I kept thinking “what did I just do?”. I have never done anything like that in the past, and I’ve been around some incredibly stupid drivers. Something this time just snapped in me, and it was almost like a reaction, out of my control. As I drove home, I kept asking myself why I did it. And what would I have done if he had reacted to my move. Or what if there had been 3 of them in the car…and they had been gangsters…with guns.

I’m not sure what I was thinking…

Oh, and then I stop at Albertson’s on the way home and one of the Pepsi Max 2 liters I was getting exploded on the moving-belt thingy at the checkout. Literally exploded. Sitting there one minute nice and peaceful, and the next minute *boom!!*, it’s on the floor behind the counter, and there’s Pepsi Max pretty much everywhere. Weird…

My Schedule…whew!…

Well, I finally got (I think) the last of my tutees and my class schedule is set so this is my 5 day Mon-Fri schedule:

Work (tutoring): 25.5 hours (I actually have 2 more hours available on the schedule but no one’s taken them yet)
In classes: 11 hours
Driving between VCC, UCF, and my house: 12.5 hours
Sleeping (as if I got 8 hours a night sleep…): 40 hours

Total: 89 hours

Wow…no wonder I’m so exhausted at the end of the week. I always said there weren’t enough hours in a day. Now I have proof of it.

You Gotta Love ‘em!

Overheard in the math lab:

Tutor: OK, so now we have two sides and we know the angle is 30 degrees. So for the next step, what is the sine of 30?

Student: Um….positive?

I almost bust out laughing when I heard that but I composed myself quickly. For those of you who don’t understand the joke, it would be equivalent of something like this:

Tutor: OK, so you know all your state capitals…what’s the capital of Florida?

Student: Um…F?

Priceless…absolutely priceless… :)

Test Week

This seems to be test week for me at UCF. I’ve already got a take-home test that is due Monday for Proof and Logic that I’m not worried about. I haven’t started it yet, but I did look at the questions and there was nothing in there that gave me pause. I should make a very good grade on it.

I took my first test in Matrix and Linear Algebra on Monday. Surprisingly, it was only 4 questions and there were no adjugates on it. Another question was solving 3 equations with Cramer’s Rule. That was very easy. The other 2 were solving a matrix via Gauss-Jordan elimination and solving a matrix via upper and lower triangle decomposition. I’m pretty confident on the LU triangular one and so-so on the Gauss-Jordan one. Hopefully I’ll get my test score back tomorrow but it’ll probably be Monday.

No test has been announced yet for my Probability class.

And that leaves Differential Equations. The test will be given this coming Tuesday and will consist of 9 questions. They will cover seperable, exact, linear, and Bernoulli differential equations, only one of which will be an initial value problem. Also on the test will be my ability to determine the linear dependence or independence of a group of functions via their Wronskian. I do not have good feelings about this test but will study as much as I can until Tuesday going on the belief that I can do good.

Probably not though…

School Update

Well, my plan to do daily updates has not faired well. I blame it on the lack of time I have for anything save school or work. So, here is a recap as to my classes over the past couple weeks.

Oh, and not getting the books for a class until 2 weeks into a class is not a good thing!

Proof and Logic in Math: So far, so good. Most of the beginning was just doing truth tables which are very easy. Then we did tautologies and now we’re actually writing simple proofs. We just got a take-home test given to us which is due on the 9th. Should be pretty easy.

Matrix and Linear Algebra: Started out real easy and ramped up pretty quick. Matrix manipulation is extremely easy but now we’re doing some weird stuff with discriminants that lost me pretty quick. I need to read the book some more and get some more problems under my belt. This coming Monday will be our first test and I want to be prepared for it.

Probabilities and Applications: Was easy but now has gotten extremely hard. We just started a section on figuring out the probability of the i-th ball in the j-th box for n balls and m boxes. It went right over my head. Plus he threw infimum and supremum limits at us which he admits are advanced calculus concepts. I am going to need a lot of practice to keep up with these.

Differential Equations: By far, the most difficult class I have this semester. I got behind by not having the book and wasn’t able to keep up with the homework. Add that to my lack of ability to do these (admittably) difficult integrations and a professor who moves like lightning and I’m definitely struggling in the class. I’m still trying to figure out the first differential equations assigned and he’s already done with Bernoulli equations and has moved on to IVP and BVP which really look difficult. I think I’m screwed…

So, one class is pretty easy (so far), 2 are difficult but I’m holding on, and 1 I’m just totally lost on. The worst thing is I increased my hours available to tutor (as I need the money) but this just puts me further in the hole as I have less hours available for studying and homework.

Wish me luck…

2 New Additions

To my math library, that is. “A Transition in Advanced Mathematics” by Smith, Regen, and S. Andrs and “Calculus 7th Edition Brief” by Anton, Bivens, and Davis. The “Advanced Mathematics” book is actually an older version of the book I’m using in my Proof and Logic in Mathematics class and I’m hoping the majority of the material is the same.

My New Schedule

In one word, it’s exhausting. Between my work at VCC as a tutor and my classes, Monday through Thursday I leave my house by just past 8am and don’t arrive back at home until 8:30pm or so. Friday is my only savior right now as I currently get home and an “early” 5:30pm-sh time but I have the potential to be working until 7:00pm.

At least Saturdays and Sundays are mine…to do homework. It’s going to be a fun semester…

At least the Monday coming up is a holiday so I have that to look forward to!

Happy Birthday Bryan!

Today is the 21st birthday of my son Bryan. He is a music major also attending classes at the University of Central Florida.

Happy Birthday Bryan!!

Day 2

Day 2 is about to start as I’m currently waiting in my Probability and Random Stuff class waiting for it to start. So far I only have one gripe. What is it with these “kindergarten” chairs they make us sit in? At my old school, Valencia Community College, for the most part we sat at tables. This was nice as I had room to put out my books, paper to write on, or later on, my tablet PC to take notes on, and we weren’t cramped. Now, for all 4 of my classes at UCF, I have to sit in these individual desks that feel like they were made for a 12 year old. …sigh…

Oh, and why does every room have a blackboard in it? Weird that as modern a school that UCF appears to be for the most part that they would still use blackboards instead of whiteboards. I was actually picturing every room would be equipped with a smart whiteboard for the professor to use. Blackboards seem so 20th century!
