In my last post I said I was now a vegetarian.

and I still am, it's been 2 days.

I feel very proud of myself.

When I told my friends they were all like "wtf?" I figured this to be their reaction.

But my little brother came into my room a few minuets ago and says that my dad doesn't believe that I am now a vegetarian, and one of my best friends said that she gives me two week.

Thanks for the support guys. Note the sarcasm.

It kind of upsets me that she thinks I can only go 2 weeks. I've never felt this serious about anything before. Anytime I smell or look at meat, I get sick to my stomach.

but whatever.

you'll see I'll prove them all wrong. 


&& I want you to check out this AMAZING band

i've been a fan of them for about 2 or 3 years, and they aren't all that well known, they will be. 

the lead singer is absolutely crazy.

think of it as a female fronted blood brothers, meets my chemical romance

and no, they did not steal gym class hereos name.

Today while I was eating leftovers for lunch, which was meat that was flavored with some asian sauce, string beans, and rice. It was good until I started eating the meat. While I was eating my food, I started to think about what I was putting in my body, mainly the meat. I started to think that what I was eating was once living, and breathing. Whatever type of meat it was [I think it was short ribs of some kind] once had a family, had a brain, and had feelings of some kind. I love animals, seriously I really do. If something happened to my cat, I would be a wreak for weeks, or even longer. Crazy, I know, but it's true. Like for example, I recently moved to a new house, and we had to catch my cat and stuff her in a cage so we could bring her with us. My cat, who's name is Hello Kitty :] She doesn't like to picked up for some reason, so we had to get a towel and throw it over her so we can get her in the cage, but when my grandma put the towel over her, I almost cried because I didn't want to hurt her. Even though we don't mean to, just the thought of it made me want to cry. I had to leave the room. 
I'm crazy I know. I love her so much. She's my favorite cat I've ever had. haha.

But anyway, While I was eating lunch, I realized what I was eating, and got sick to my stomach. I really did. I had to put my bowl down, and take a deep breath. 

From that moment on, I thought, "I'm not doing this anymore, no more meat, no nothing, I can't do it." 
I know it's going to be hard, especially in a place where I'm surrounded by meat. My mom is mexican, so we have burritos a lot  [no, not the taco bell kind] I'm talking authentic burritos, with seasoned steak, all the good stuff you know? 

No more spam musubi's. [trust me, they are soooo good.]

But it's worth it. 

From this day on...

Momentum, was actually introduced by the French scientist and philosopher Descartes before Newton. Descartes' idea is best understood by considering a simple example: think first about someone (weighing say 45 kg) standing motionless on high quality (frictionless) rollerskates on a level smooth floor. A 5 kg medicine ball is thrown directly at her by someone standing in front of her, and only a short distance away, so that we can take the ball's flight to be close to horizontal. She catches and holds it, and because of its impact begins to roll backwards. Notice we've chosen her weight so that, conveniently, she plus the ball weigh just ten times what the ball weighs by itself. What is found on doing this experiment carefully is that after the catch, she plus the ball roll backwards at just one-tenth the speed the ball was moving just before she caught it, so if the ball was thrown at 5 meters per second, she will roll backwards at one-half meter per second after the catch. It is tempting to conclude that the "total amount of motion" is the same before and after her catching the ball, since we end up with ten times the mass moving at one-tenth the speed.

Considerations and experiments like this led Descartes to invent the concept of "momentum", meaning "amount of motion", and to state that for a moving body the momentum was just the product of the mass of the body and its speed. Momentum is traditionally labeled by the letter p, so his definition was:

for a body having mass m and moving at speed v. It is then obvious that in the above scenario of the woman catching the medicine ball, total "momentum" is the same before and after the catch. Initially, only the ball had momentum, an amount 5x5 = 25 in suitable units, since its mass is 5kg and its speed is 5 meters per second. After the catch, there is a total mass of 50kg moving at a speed of 0.5 meters per second, so the final momentum is 0.5x50 = 25, the total final amount is equal to the total initial amount. We have just invented these figures, of course, but they reflect what is observed experimentally.

There is however a problem here--obviously one can imagine collisions in which the "total amount of motion", as defined above, is definitely not the same before and after. What about two people on rollerskates, of equal weight, coming directly towards each other at equal but opposite velocities---and when they meet they put their hands together and come to a complete halt? Clearly in this situation there was plenty of motion before the collision and none afterwards, so the "total amount of motion" definitely doesn't stay the same! In physics language, it is "not conserved". Descartes was hung up on this problem a long time.

Explain to your classmates what Descartes was missing in his analysis.



Anybody care to explain?

i hate how all my friends are older than me. 

because tonight we all planed to go see Superbad, but then they call me and go 

"i don't know if you can get it in." 

"why?"

"cause the movies rated R, we all can get in, but i don't know if you can" 

I&&*&&*!&@^#@

GRRR that makes me mad because you have to be 21 to buy a ticket for a minor, but if your 17 you can buy a ticket for yourself.

and ALL my friends are 17 and older. srsly.

but were going to try and get in anyway. when they go to buy my ticket, i'll just gracefully walk away.
