Hello there,
I have always loved physics and wanted to get a degree in physics, particularly particle physics. But my father told me that if i have a physics degree i won't be able to get a job easily so i should pick an engineering course instead. i looked through engineering types but i...
I'm a final year high school student trying to figure out what he wants to study in university. I have decided on an applied math double major with one of the above. My dilemma is between deciding to purse the passion I have for theoretical/ pure physics or an applied science as I would really...
Hello,
I'm in sort of a strange predicament. I need to figure out how to install a bunch of software that we don't have install programs for. They did at one time, but I think they've been lost by the employee before me or even before that.
Luckily though, I do have servers with the program...
hello all, I am currently a college student studying energy systems engineering, i was just wondering if there are any ways to get into the habit of understanding math it's not my strongest subject. Also just a random thought, where do you think energy/ electrical engineering will be in the...
How are the problem solving skills you gain from majoring in Physics and majoring in Engineering different?
I have noticed that a lot of people think you get better at problem solving by majoring in Physics when compared to engineering, and I don't understand why. I mean, they both study the...
I always hear that mechanical engineers (at least ones without a ton of experience) rarely ever do any math. I really enjoy studying mechanical engineering right now, and I really want to make sure that the stuff I'm studying is what I'll be using on the job.
How does a mechanical engineer (or...

I am a high school senior debating between these two majors. In high school, I enjoyed both Mechanics and E&M very much so its really tough for me to decide which of the two engineering fields I'll like more. Whichever field I pick, I am also planning to minor or double in Physics and Computer...
I would like to ask about some terms of control engineering.
What are other common expressions for "moving a pickoff point" which can be used as" moving a pickoff point behind of a block" or as "moving a pickoff point ahead of block."

Thank you.
When solving for the hydrostatic force on a surface we use the height to the centroid(hc), then when using the point of application we use the y coordinate of the centroid(yc), however shouldn't they be the same since they both start from the top surface and reach down to the object surface on...
The equation for momentum (potential energy) is PE=M*V.
The equation for kinetic energy is KE=(1/2)*(M*V^2).
You will notice that PE is the derivative of KE. and then you might add that M, simply Mass, is the derivative of PE.
However, because M is simply a scalar quantity, and the other...
Can I major in Electrical Engineering and Biology and become a Biomedical engineer? I want to be a Biomedical engineer but the school I am going to only has environmental, electrical, and mechanical.
Hello Dears
I am Mechanical Engineering Technology and I am thinking to get Master degree in Nuclear Engineering/ Nuclear Mechanical Engineering. So, is it possible to do that and in which university?
Thank you
Suppose I have a tank which is made of steel coated with a thin layer of glass on the inside to protect the steel from corrosion (the material stored inside the tank is corrossive; say for arguments sake Water with 10% Hydochloric Acid).
In theory, till the glass is intact there is an...
If I have a BS on Physics, could I move and pursue into a MS in Aerospace engineering without having a BS on Aerospace E.? Would be easier if I had a BS in Astrophysics?
Which is better? To study dynamics through physics or through mechanical engineering? What is the difference really?

The scientific process.
An engineer once told me a joke:
"A scientist is considered a success when his peers agree with him. An engineer is considered a success when he actually gets it right."
After a physicist's comment today I am starting to think it wasn't a joke. The physicist said if...
Hello everyone, I want to give some brief background info about myself before asking; I am a junior/senior undergraduate living in Southern California studying mechanical engineering, and leaning towards the thermo/fluids side of mechanical engineering. However, when it comes to "my true...

I'm a high school junior who thought I wanted to be an engineer (because I enjoy and am good at math and science), and I decided to take AP physics 1, but I now realize that was a horrible mistake. I am doing terrible in the class, and although I kind of enjoy the ideas I hate the math for...
I was on the grad cafe looking at admission statistics. It looks like it is much more competitive to get into an engineering PhD program than it is a physics PhD program. Is this true? Most of the GPA's of people who got into the engineering PhD programs had a gpa in the mid to high 3's while...
