I have a code in Matlab where I need to measure the radiation on a specific latitude over a year. I have my time steps in hours and I am iterating over a year. I have parameters for the amount of radiation per hour in a 24 hour period, but my problem is that I want to loop this 24 iteration loop...

Can someone recommend me some good books of those subjects? EDIT: Sorry, I meant calculus, not chemistry.

Basically, I skipped A levels and went right into Bsc Economics & Finance. I'm graduating this year and am planning to take a second degree in EEE because I don't like my current degree. I choose EEE because I have passion in science and technology, and working in the tech sector is something...

Currently, I'm a junior Biology/Studio Art major who became disillusioned by the allied health field very early on and then the biological research field very recently. I have been looking for something else to do with my life, but every subject (psychology, English, chemistry, biology, history...

Ok so I started this year as a pre-health major so I took the non-major physics classes (non calc based) and enjoyed them so much I want to take the calc based classes and start anew with physics next year. I did mechanics in semester 1, and E&M and optics and briefly touched on modern physics...

I've heard from a few people that chemistry courses get quite hard when the 2nd year starts. I would have thought since you start to specialize in chemistry there will be a lot of overlap between classes which would make things a bit easier. I was thinking about trying to double major so I can...

redshift ""first year astronomy"" how do i find distance using redshift? please keep in mind that this is first year astronomy course i am currently taking having some trouble doing it. don't know where to start

Hello, I'll be finishing my freshman year of college soon and I'm pretty saddened as to the results of my academic performance. I am currently a Physics major and after my first semester I pulled off a dismal 2.7 gpa. This semester I was working for a big change, but I guess this was mainly talk...

I love physics, especially particle and astronomical physics, and for my intel research class which I will be taking next year, I would like to study them more. For this class, I need to choose a topic of study to which the answer is unknown or poorly understood and "play scientist" for a year...

Hi all, First I just want to say that I find this forum really interesting and very helpful - so thanks to all those who answer these questions! Onto my questions - I am a Junior physics major considering what classes to take next year. I am lucky enough to have all of my requirements...

It's been a while since I've posted here, but since my last post I've become more entrenched in the terrifying mess that is late junior year/early senior year, and the college hunting and decisions that come with it. I realize there are tons and tons of threads about this stuff, but I have some...

Hope this is in the right place. I'm 13 years old and I would like to self-study physics. I've study most of calculus and some differential equations and linear algebra. But due to my eagerness and perhaps lack of guidance I have many gaps in my foundations. As I have little access to books...

Homework Statement Consider two friends who go to Burger King every day for lunch. One of them orders a double whopper sandwich large fries and a large coke (total cal = 1600) while the other orders a whopper junior small fries and a small coke every day (cal = 800). if these two friends are...

I was watching a video on the scale of the observable universe. At the end, it shows the famous WMAP imagery and at the bottom it reads that the age of the observable universe is about 13.5 billion years old, but that due to the expansion of space the actual age is closer to 93 billion years. I...

I have never done any programming (except very basic python stuff in 1st/2nd year physics), and I want to learn some a bit more in depth over the summer. Can anyone recommend which programming language I should learn? What's most-widely used for physics/astrophysics?

hey guys, i need some advice as to which math class to enroll in. i just got accepted to college and will be starting first semester of freshman year in september. i will be a math major, and i am really comfortable with math. So right now, i am in ap calc BC and i am confident that i can get...

I was accepted to a PhD program in Materials Science and Engineering at a prestigious university and I find myself reconsidering immediate entry into the program. I am very intent on earning my graduate degrees from this school, but I would prefer to begin classes in the Fall of 2011 if given...

Hi everyone I will try to be brief. I have completed my junior year as a mathematics undergrad. I am seriously considering taking a year off before my senior year as an undergrad. This is not so rare at my university. I want to do this because I realize I have a very poor foundation in...

Homework Statement Why does a superconductor have a greater magnetic field because of a. its interior has no magnetic field and b.it has no electrical resistance Homework Equations The Attempt at a Solution

Hi, I'm looking for advice on how to look for summer research in physics. I don't even have a area I'm looking for, anything thing is fine; I'm just looking for experience. Most of the programs for summer research I seen at my school are for 2nd,3rd,4th years. I'm at a pretty big school (Uof...

Do you think it is possible to complete a PhD in theoretical physics in just one year, since no experiments have to be done?

Zhonghui Liu of the University of Hong Kong has made the most comprehensive deep-sea core research to date http://www.sciencemag.org/cgi/content/abstract/323/5918/1187?ck=nck. Global SST's fell by an average of 4.5 to 6 degrees F at the E-O boundary, with temps near the South Pole and North Pole...

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...

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...
