What should I post about???
I'm seriously running out of ideas for creative posts, guys. So instead of posting something witty/funny/complete crap, I'll post about my friend Allison. (And Quinn, because she just asked me to.) We're all sitting together in history class right now, not doing much of anything. We took a practice test, but we finished earlier than the rest of the class. I've known Allison since 4th grade, or so I've been told. I've known Quinn since kindergarten. (Kindergarten sounds German, doesn't it? Allison just informed me that it is in fact German. It means 'child's garden.') Okay, well school is over, so I had better stop talking about my nice friends.

Pascal's Triangle
Recently in my math class we were taught about a thing called Pascal's triangle. I am not sure if this is my synesthesia kicking in (post on that coming soon!) or if its something else but I find Pascal's triangle to be one of the most amazing things, like ever...
I am writing this post to raise awareness to Pascal's triangle since many people I have talked to have no idea what it is. According to Wikipedia, "Pascal's triangle is a triangular array of the binomial coefficients in a triangle." This here is Pascal's Triangle (and it goes on forever.)
See a pattern?
One of the cool things about our friend's triangle is that it is simple to write. All you do is start with 1 at the very top and then go down and put 2 1s. The rows are created by adding the two numbers above it. Say you want to create row 3 (#1 is the zero row so we are talking about row 1 3 3 1) then you just look at row two and see, "Oh, 1+0=1 (the first digit), 1+2=3 (the second digit)..."
Don't think its neat yet?
Well! Prepare for blastoff Elwood, because I am about to make you think this is so neat that...I dunno... but its neat.
So say, your teacher gives you the problem, (a + b)^4
You would find the 4th row in the triangle, (1 4 6 4 1)
Then you would write
1 4 6 4 1
Then put in 1a 4ab 6ab 4ab 1b
and add the exponents starting at 4 for a on the left and 4 for b on the right
and you would get:
a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4
I just think this is really neat and my apologies for bursting into geek mode...

Video of the Month: May 2012
Sorry, but I don't have anything witty to say. It's the end of the school day on Friday, and I just want to sleep. Anyways, here's the video of the month.
Happy May, everybody!

Welcome, 0ld_Sp1ce!
Please give a warm welcome to our new author, 0ld_Sp1ce! We happen to know each other in real life, and since the blog's quality is crashing and burning, I came to him for help.
Yeah, that's pretty much the way it happened.
UPDATE
I have also changed the look of the blog to welcome 0ld_Sp1ce. I particularly like the way that it looks now, so I'm considering making this the norm. If you want your opinion heard, weigh in using the comments section. (Not that anybody actually will. Seriously, guys. Are you afraid of the comments? I feel like I'm talking to a wall here.)
Elwood: Hey, 0ld_Sp1ce.
0ld_Sp1ce: Hey.
Elwood: My blog sucks.
0ld_Sp1ce: I can help if you want.
Elwood: Okay.
Yeah, that's pretty much the way it happened.
