MIT receives thousands and thousands of appilication every year, but do you know what's the percentage that get accpted? 14% in 2005, and 98% of people who apply there have a GPA of 4.0 and Sat score at least 1590 in each verbal and math section of the old version of SAT.

Do you think you can make it???????????

be realistic

poor people can't afford a car, but they need it to go to work.

on the other hand

rich people can afford nice cars, they use it for entertainment.

Why? Why? Why is the world so unfair?

Then what caused the inequality distribution of wealth?

recently i realized things are not fair sometimes, like things in life. for instance, a rich person have lots of money so they can purchase a car, but they might not needed. On the other hand a person doesn't have much money, but they may need a card badly, and they can't afford it.

Can anyone tell me why this phenomona so common?

If a quark is elementary, what makes them "appear" in 6 different forms?

The reason why they appear in 6 different forms is each quark contains different energy or power. For instance C quark has 1.5Gev, but S quark has 90eV.

When the temp. rose around 80s' my body slows down a lot, and I'm not well concentrated either. ( this case only appears to me inside of the house). When I went to backyard and play basketball I felt this intense energy coming out of me, all of a sudden i felt like to Tracy Mcgrady. Can someone explain to me why i felt so different at the same temp. but doing different activities.

thanks dave

my problems is i got stuck while i was trying to find the domains of a function,

1) f(x)=(x^3)-(3x^2)+(2x)+5

2) g(x)=(x^2)+5/(x+2)

can anyone determine the domain of the two functions?

Thanks a lot!

We don't know what caused the planet go in orbit. Gravity is caused by the curvature of space time.

what i think it should improve is the speed. It runs very slow on my PC.

It is really a waste of time to read all the comments posted by the people on this forum who do not have any intelligence.

When I mix vinegar with baking soda, it produce gas. But it also produce salt, I'm confused on how does gas related to salt.

i disagree

i remembered dr.feynmen said something about active molecules. It has a 2 percent possiblility on every rotation of the electron orbiting proton. And a T + V transaction between the R + T.

but later we discovered that electron do not go eliptical order or in circular path.

I definitely think your grades are more representative of your work ethic and not your intelligence.

What do you mean by work ethic?

Some people appear to me as if they know everything. And they probably do know a whole lot more than me. I made a promise to myself, I need to try really hard to catch up with them.

Thank you mart for your good advice. Tell the truth I didn't expext any answers. I have already tried these two problems myself, and i can't solve it. I know I should do these myself, but that's not required.

1) At 10 p.m. a 5 foot 6 inch tall young lady is directly below a street lamp which is on a pole 25 feet in the air. This young lady begins walking in a straight line away from the street at 6 feet per second. After how many seconds is the shadow she casts 11 feet long?

2) Given triangle ABC. Let E be a point on line AB and D be a point on line AC such that line DE // line BC and BD bisects angle ABC. If AE=4, AC=18 and BC=15 then what is the length of DC?

hey thank you jordan for your good advice. I think that's what i needed the most.

ed84c I don't think I am bored with the work, it's quite the opposite I didn't get enough fundation of physics and try to clime up too high. But thanks for your advice.

people I really worked hard in the course of physics but I still get a B for the semester. I felt depressed. I don't have any motivation to go on and study, and I'm tired of not to accomplish anything. do any of you have any suggestions on what to do?

thanks dave i believe your first post was right. Thanks to you also ed84c, your first few steps was right, but i think you are a little off at last few steps.

If ex - fy= gx + hy find ratio of x to y

Answer is highly appreciated.
