An idea about gravity that isn't correct but is still cool
So, our universe is expanding very quickly. Expanding not in the sense that more matter is being created and adding to the edges of the universe, but rather our universe is stretching like a piece of rubber being stretched in all directions. So, as this rubber is being stretched, each planet gets further and further away from each other planet and the distance between any two points in our galaxy (or universe) is getting larger.
Now, to slightly switch topics, when Einstein came up with the idea that gravity is the curvature of spacetime, his wonderful idea sprouted from the idea that, if a car is constantly accelerating, then the person inside it will feel a constant force from the back of the chair. This force, if the acceleration is 9.8 m/s^2, then would be the same as gravity and, in the absence of earth's gravity, would feel exactly like gravity.
So now, back to the first paragraph, if our universe is constantly expanding, then doesn't that mean that the mass in our universe is expanding, too? We would not be able to measure this- one might say that the density of an object would constantly be going down, but if it is in fact the atoms themselves that are getting larger and larger, we could not measure this and, since we would be growing at the same rate as everything around us, we would seem to be not growing at all. But let's say that the matter below us is growing very, very quickly and we ourselves are growing very, very quickly, then there would be a force exerted by the ground on us, resembling gravity.
No, wait, the expansion of mass has to be accelerating to begin with, just like the accelerating car (we wouldn't feel a force if it was just constantly expanding). http://en.wikipedia.org/wiki/Accelerating_universe
Wow, I swear I didn't read that before I made that last statement.
But, yeah. Probably wrong. Fun to think about, though.

"I have seen the others and I have discovered that this fight is not worth fighting
And I've have seen their mothers and I will no other to follow me where I'm going
So, take your shower, shine your shoes
You got no time to lose
You are young men you must be living
Take your shower, shine your shoes
Well, you got no time to lose
You are young men you must be living
Go now you are forgiven"
Why is this such a good song? Because people are avoiding human nature?
On another note, I love school, pretty much.

random...I need to start my 11 page paper
No words can explain how content I am with everything right now.
Now, this will sound awkward, but I had a dream last night that something happened, my mom got a phone call, and she was freaking out saying that "this could be bigger than 9/11"...that's what stuck in my mind, the bigger than 9/11 thing (even though I didn't know what had happened). Then, in my dream, I went on cnn.com (lolz, I am a loser and check their homepage constantly) and there was like something saying that like 300 some people were dead from some virus that spread from 1 to 300 in like hours.
But, yeah, so much for the nightmare, but then today I did an eerily similar thing by going onto cnn.com just to make sure everything was chill and I saw that the freakin United States Economy is royally screwed. They're comparing it to the Great Depression. Couldn't help but compare the bill not passing to 9/11. In the end, I think the former will have a greater, more lasting impact on us.

Ah, the drama. Tis not good, not good at all. Although it is more other people being stupid and dramatic and me just watching them and telling them to stop saying mean things about their friends. And by telling them, I mean thinking.
Time to go hang with some amazingly cool kids (that aren't being dramatic)

what I just sent to my physics professor (Warning; it has to do with sound waves and...science.)
"The goal of this is to find out the wavelength of one sound-wave with a fairly high accuracy by using a combination of a wave of a known wavelength and the unknown wave. From my experience, sound waves which are very close to each other in frequency and which are sounding at the same time end up creating a third pulsating noise. This pulsating noise is due to the additive property of the waves (when waves “sync up” with each other, they add to each other and increase in amplitude). Using the time of the period of the addition of the unknown wave and the known wave, one can find the wavelength of the unknown wave to some accuracy.
Vs=Speed of sound
λ1= Wavelength of the known wave
λ2= Wavelength of the unknown wave
t1+2= Period of combination of λ1 and λ2
W1= Known wave
W2= Unknown wave
First, find how many cycles of W1 happen in t1+2
(Vs)(t1+2)/( λ1)=Cycles of W1 per period of t1+2
Now, we know that (if W2 is slightly smaller thanW1) the unknown wave will be x meters smaller than the known wave. Therefore, we know that (x)(the number of cycles in wave W1 over t1+2)=(wavelength of the known wave). Therefore, (Wavelength of the known wave)/(number of cycles in wave W1 over t1+2)=x
(λ1)/[((Vs)(t1+2))/ (λ1)]
Which is equivalent to
λ12/[(Vs)(t1+2)]
This gives us the “x”, the difference between the λ of the known wave and the unknown wave. Both waves will interact the same if they are x meters larger or x meters smaller than the known wave.
(λ2) ±(λ12)/[(Vs)(t1+2)] "
So I am a loser...

College is amazing. Here are the things I will do this year:
Join the Ultimate team (done)
Hike the tallest mountain in Maine (done)
Hike the tallest mountain in Maine in the winter
Go on a back-country ski trip
learn how to telemark
Do the puddle jump (jump into a hole in a frozen pond)
win a ski race
join the downhill ski racing club (this one should go before win a ski race)
find someone who will talk to me more than I talk to them
Get an "A" in a hard class
Have more than 2 beers. (Maybe not?)
go skydiving (a longshot-although there is a skydiving club)
sled with my friends
Travel with the ski club
Join Outdoor Track
Join a sports team that I have never played on before
pull an all-nighter (not that I want to...)
HAVE FUN
and....a lot more
So, basically, although I may miss High School, college is cool. A lot of work, but cool.

Three Days
I'm so sad to be leaving what I am leaving, yet I am so happy to be going where I am going. In three days, I will be in the wilderness of Maine. In three days, it all starts over. In three days, it all begins.

physics stuff
So, let's say it is possible to go the speed of light in a spaceship. And one of the laws of physics states that as you speed up toward the speed of light, time time slows down and is eventually zero when you actually get to the speed of light. So let's say we are in a space ship traveling from point A to point B. If no time elapses when the ship travels from A to B, then surely the space ship must be going infinitely fast.
Hmmm...but not really. Time does elapse outside of the space ship but it does not inside of it. So we will see the ship travel from A to B, but the ship itself (from its point of view) wouldn't be traveling from point A to B but instead "jumping" between the locations-without having any time elapse in between. In this way, (although laws of physics also state that you cannot get up to the speed of light) a rocket could travel from earth to another far, far away planet and the person inside of it would not even believe they went anywhere. The only problem is how would you stop the space craft? It is going at the speed of light so even if you set a timer to slow the rocket down in .nth of a second, that tiny amount of time would be infinite if time slowed down to a halt. The only way to stop it would be with some external force, I guess. Although accelerating to the speed of light without killing somebody with the force of acceleration would be a pretty difficult feat in itself.
I've spent an amazing amount of time biking and thinking and doing nothing. I wish people would include me more often. Maybe I need to include myself more often.

So I am in Spain. It is very cool and very hot and very...very interesting. Don´t know what else to say other than the fact that my parents dropped me off at this sketchy internet cafe thing and I am surrounded by people I should be able to understand (hence the 6 or so years of learning the language) but somehow I can´t. I am off to France in about a week or so and then off to Italy then Switzerland then I don´t even know where till July 2nd. It will be fun, but I miss so many people back at home like crazy. Like CRAZY. It is kinda like the whole point of going on trips is to look at cool new things, but I have just discovered some very cool new friendships back at home which I must leave for a month. Ok, so I have about....3 seconds left in my 15 minutes on this computer...

The Horizon Effect
Imagine a beach ball full of air. The air is trapped inside the beach ball and slightly pressurized. Is the beach ball is forming a sphere around the air inside it, separating that air from the rest of the universe, or is the beach ball wrapped around the rest of the universe, separating that from the air inside it?

Comatose
So I am obsessed with this song "Comatose" by Timmy Curran. It is like...woah, this has to do with so much stuff right now. Especially the whole going off to college thing. And like the whole global warming thing. Gotta "wake up soon."
If we don't wake up soon.
All we ever knew will be gone.

It's finally getting to be like summer again
So I may not get a varsity letter. So I may not improve like crazy. But like, I am so happy that I am improving at all. Sports are meant to make you happy, and obsessing about getting a varsity letter isn't really that much fun.
And basically, I miss some people on the ski team like a bunch. I want so much to have a group of people in my life like that right now. Luckily I have some people on the track team. Too bad the track team can't be co-ed like the ski team.
In conclusion, I love warm weather and CANNOT wait for summer. Well, actually maybe I can. I love the feeling of having something (and basically everything) to look forward to.

Finally.
And then there were two.
Bates and (I wanna say SLU just to rhyme, but that's the one I just took off my list) UVM. I'll know which one by next week. I'll know where I'm going to be for the next four (hopefully) years of my life in the next week.
Good times with my sister over the weekend. Dartmouth is a sweet school.
"Yeah, and he was basically just freaking out about life"
"I've never met any teenager who hasn't freaked out about life"
In other news, the track team is amazing. And so is Newton Faulkner, and so are the Red Hot Chili Peppers, and staying up late, and thunderstorms, and rain, and the spring, and school, and life. Just basically life is amazing.
