I am reading about the eligibility criteria in order to employ researchers they ask non older than 35 years old and also if you want to apply for an assistant professor. I just do not understand why. I know someone who had almost 5 years before university a job and switched the professional...

"you're in pretty good shape" first year physics textbooks.. Hi, I'm wondering if there were any books for which if you were able to do the problems, then you're in good shape.. For example, if you can problems from Spivak's "Calculus" book as you are in your first year, then you're in pretty...

I had been talking to my seniors about applying to colleges once one is done with a BSc. In India, BSc degrees are only for 3 years, and I've heard that many colleges in US do not accept 3 year degrees when applying for masters, but only 4. I have also heard that since certain colleges offer BSc...

Homework Statement I want to convert wavenumbers into wavelength. The wavenumber is 400cm-1 and i used the expression v=vbar*c to get the frequency in Hz to be 1.2*10^13, I also remembered to convert c into cm/s so that frequency is in its SI units (seconds). I then simply thought that I...

Year: " The period of time during which Earth completes a single revolution around the sun, consisting of 365 days, 5 hours, 49 minutes, and 12 seconds of mean solar time." http://www.thefreedictionary.com/year" It seems very clear to me that a year does indeed exist, but I recently had a...

Happy New Year and may this be the best year of your life!

When do we run out of uranium? How much is used per year? How much is in stock piles? How much is in deposits that we can afford to extract?

The beginning of a 'new' year seems to invite aspirations of 'doing' something. It has been proved to some extent that writing down what goals a person has helps that person to plan more vigorously to achieve those goals. Large or small, on a level of a personal nature, or more of a...

It's suddenly started creeping up on me that the degree is almost over, barely having even started, and I was wondering about internships and things. We've just been sent an email by the department about penultimate year internships, which as I'm on a 4 year course I'm not that far yet. Still...

Hi I hope I'm posting this in the right section. I am trying to find some experiments that would be appropriate for an introductory biophysics course for some second year students. Any links/pointers in the right direction would be great, although I'm specifically looking for enzyme/molecular...

I have an undergraduate degree in chemistry. I'm taking some physics classes and I plan on eventually getting a PhD in physics. I plan on getting a master's before I go for the PhD. This will allow me to fill in some gaps in my physics education. My question is, what are you guy's thoughts...

I've recently become aware of a supposed well known fact, that actually seems quite wrong. It is said in many places that the difference between the Tropical Year and the Sidereal Year is about 20 minutes. Here are some examples on Wikipedia, but I've seen this in astronomy and science...

Well it's my senior year and I was pretty set on being an engineer. But an engineering student came in and talked to us about what it is like. He said that it was nothing like what he imagined; he became an engineer because he wanted to be active doing things and creating things. He said that...

Hi, I'm a second year physics student (doing a 4-year course) at Durham university and I really want to get some relevant work experience this summer. I've looked into a fair number of placement programmes (like IAESTE UK, the Nuffield Foundation, RISE etc.) both abroad and in the UK, but...

next year I am going into my sophomore year in high school, i think I am taking physics. will it probably be challenging? hope this isn't the wrong place to post this, it probably is though :(

Hello. This is a long post, so some of you may find it a bit boring, and you probably won't want to read all of it. I've read some of the posts related to my questions, but my situation is a bit funkier so I decided to make my own post. Thanks for reading. Questions start with bold numbers...

Is first year math in an university just Calculus I, II (or AP Calculus BC), and III?

I've been studying at my local community college since spring of 08 semester, including summers. I'll be finished with calc 1-3, diff eq, lin alg, statics, chemistry, physics 1-3, engineering 1, and possibly dynamics by the time I transfer. I haven't spoken with a Cal Poly adviser yet, just my...

How much more rigorous are the science and math courses at a university compared to science and math courses at a 2 year college. On this website called assist.org , it shows you all of the classes you would need to take at a particular 2 year college to get to transfer to a 4 year college...

It says on the engineering page at the 2 year college that, students who are studying engineering may not be best served by studying at that particular school, anyone have any idea why that might be It's on the counseling link where you can click on whichever career you want to prepare to study...

I am planning to become a physicist. But here is my question. Next year I will be heading to a post-secondary institution; however, I am unable to decide whether I should go to a college or university. Here are some problems 1. Money isn't a BIG concern, but it's always good to save up...

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...
