I'm just out of high school and will be starting an advanced mathematics course in University (NSW, Australia). I'm unsure what each course consists of specifically, and all I've really heard about that will be in it is "discrete mathematics". It's vital that I get good marks on average...

Are there more in say , Colorado, than there are in California ? And Which state, given the choice, would you prefer to study science, engineering, or math in ?

Can anyone recommend a school in California, other than: UCLA, Berkley, Cal State North ridge, or Sandiego, that offers Electrical engineering , and physics

go to an average 4 year college like the University of Santa Barbara , and have grades of C and just a few A's or B's , as opposed to if you have all A's and are going to Berkley ? Really curious about how employers view grades and what school you went to in making a hiring decision

at the end of these 100,000 year cycles of temperature, what causes the peak temperature to fall?

Not all of them do, I've checked, or they only offer a few types of engineering. Like if anyone goes to a particular school and knows which engineering degrees are offered. & how much per semester does it usually cost to attend a 4 year college to study engineering?

Hey guys, I am a freshmen mech engineering student and so far I have been really disappointed in my college performance. I am on an academic scholarship that I need a 3.0+ to keep, which I thought would be no problem at all. However, I don't know what I am doing wrong. I just took a math test...

Hi everyone. So I am almost a senior math student. The senior year is obviously difficult and the classes small, and I was worried that I am not going to be friends with any of the other senior math students. This means I will be working on my own as opposed to in a group like the other...

What are the physical possiblities if the ,astroid Toutatis , crosses directly between the moon and Earth on December 12th 2012. I understand that this is a fairly large astroid and is projected to zoom near Earth somewhere in the range of the distance between Earth and the moon. What are the...

Hello, I have been reading this forum for about a month and I'm very glad I found it. My journey is peculiar, uncommon, odd, and some might argue that it's impractical; but some people say that things happen for a reason. I'm 24 years old and still in school, the road I've traveled has been...

Hey guys, I'm starting my sophomore year in high school this week and I'm intending to study for the physics olympiad for the next two years but I had a question about how to manage my work load. I already get a lot of work as I go to one of those competitive high schools, but I'm making it my...

When you study physics for the first time in school what grade,class or year is it? And what are the topics in your first year? I live in Pakistan and we start Physics in Class 9 (at approximately 16 years of age). The topics we study are as under. -Measurement -Kinematics -Scalars and Vectors...

Unfortuantely I did not do so well in Newton mechanics in the first year physics course. In brief, I decided to take the honors version with no prior physics experience and no care to try to fill in the gaps. Fortunately I managed to pull off a C overall but I hardly retained any information...

NOT the total distance that we have traveled, straight, curved, or whatever, through space but how far are we now, direct line, from where we were a year ago, say within 10% or so? I understand that there are a few motion items involved with this but I am looking for an approximation only. Just...

I am getting ready to move into an appartment on campus. This will be my first year on my own, the previous years I was living with family. My mother told me I should keep nothing in my car and leave it unlocked, so that if someone does break into my car, there is nothing to steal and nothing...

In the back of the economist there are articles about new research. One of them was about a paper published in science I think. It concerned deviations form what general relativity predicts for the velocity of space probes. I said that the measured velocities of a probe or probes was out by...

Raymond explains in his radically modern physics text on page http://physics.nmt.edu/~raymond/classes/ph13xbook/node61.html that a constantly accelerated observer (acceleration a) never increases his distance from the point x_0-c^2/a where x_0 is the point where he started his acceleration...
