Hiho, long time since I've posted here. So I've been thinking about 1 or 2 things. Globular clusters are assumed to be the earliest structures formed in the universe because they are roughly the size of the Jeans length. But I'm thinking that if the universe was very nearly isotropic the...

Hey Im a physics student and was told that a mechanical engineer may think or i good idea to help so here goes... (this is what I've posted in the physics forum) Hello I have to complete an experimental physics project for high school physics this year and with help of the physics...

Here is a cool tour inside of a Genetics Lab. Make sure to check out the zebra fish mutants and the mouse guillotine! :eek:

Hi everyone I have a few conceptual questions about velocity and acceleration. Can an object increase in speed as its acceleration decreases? If it does, can you guys give me an example? Can an object have zero velocity and nonzero acceleration at the same time? Also give some examples...

Hi. I just recently switched into a physics course midyear, and I really don't know what's going on. Help with a few of these questions would be greatly appreciated. Homework Statement A 2.5 kg ball strikes a wall at 8 m/s and rebounds at 7m/s. The ball is in contact with the wall for 0.2...

Hello, I am quite new to this forum and I first just wanted to say that I love it. Now on to my question. This last year I have found myself really interested in physics and have been reading about it like crazy. The problem is last year, as a junior in high school, I had my physics class and...

This is my problem: 1. A 56.2-kg high-school student hangs from an overhead bar with both hands. What is the tension in each arm if the bar is gripped with both arms raised vertically overhead? 2. What is the tension in each arm when the arms make an angle of 35.00 o with respect to the...

Hi all! I am a final year mechanical engineering student. I am kind of confused about my choice to do mechanical engineering... I love mathematics and physics. I am comfortable with those theoretical and abstract concepts that most of my classmates are not really into them. Like classes of...

Hey everyone. I'm a sophomore in Electrical Engineering, and loving it (except for the homework...and tests...). Anyways, it's almost time for me to be applying for scholarships (well, in a couple months), and I was thinking about applying to IEEE as a student member. I was wondering if anyone...

This is an unbelivably disturbing story; some seriously depraved "police" attacked and repeatedly tasered an immoblized student on the floor of the UCLA library, while a large crowd watched. The unarmed Muslim student allegedly became confrontational after been refused entrance (he forgot his...

How much work is required for a 50 kg student to climb a 10 meter ladder? i know that work = f x d but it doesn't tell the Newton so what do i multiply with 10 m?

A horizontal platform in the shape of a uniform circular disk rotates on a frictionless bearing about a vertical axle through the center of the disk. The platform has a mass of 150 kg, and radius of 2.00 m. A 60kg student walks slowly from the rim of the platform toward the center. If the...

I'm currently attending the University of Minnesota in the evenings, waiting for my wife to finish her Ph.D. I plan on going back for a B.S. in engineering, but I haven't picked a field yet. I'm currently taking Calc II, and have the following classes left to take before I start full time...

I might not be the brightest bob in the bunch but I am having trouble with a simple quadratic equation. k^2 + (k + 4)^2 = 346 According to my manual expands to: k^2 + k^2 + 8k + 16 = 346 Everything is going fine until I see the 8k. Where did the 8k come from? Or is my...

am a little behind in my engineering curriculum but not to worry. right now I am taking Calculus 1 and Physics 1 for engineers, along with two excessively hard CSE courses. I have gotten **** poor grades thus far because well its really hard for me to study all of this in a given day. I just...

It's official! As of 1st of October I'll be granted a part-time assistentship, which will enable me to start my PhD. A bunch of research groups have already expressed their interest, but my first choice will remain theoretical particle physics. This means that I will also have to teach the...

I plan on entering into an engineering program net year as a first year entrant. My grades should get me into the engineering program if I apply for first year entry. But should I do this? I only recently (grade 11) started taking my school work as seriously as I do now. My marks are in the...

Hopefully I'll be getting a laptop for my 18th (v. soon!) and I need advice! I've been looking at macbooks and they're so pretty...but how difficult would it be to switch from microsoft to OSX in terms of learning to use it? Can anyone advise me as to which would be the best for a student...

I'm trying to get perspective on what life is life for a physics grad student, namely on the social side of things. When I was an undergrad (UC Irvine), it seemed that the majority of the graduates at my school were dedicated, quiet, and exceedingly introverted. However, my sample size is very...

I need a book that will explain tha statistical methods that we use in the analysis of the laboratory exercises done in the first years of a physics course. Stuff like standard deviation, standard error etc and also in handling errors. I know the formulas and some general instructions on where...

I am currently attending a community college and I have completed 28 units and am taking 6 units right now in the summer. I plan on applying to the UC's but my primary choices are UCLA and Berkeley. Since I plan on being a theoretical physicist and getting a ph.d to study string theory...

I'm not mighty. I suck. Man, am I in a Donatella Versace mood. :mad: I swear if anyone walks in my office I'll throw things at their head. GET OUT! grrr. I hate midterms. I hate neuroscience. I hate artificial intelligence. I hate essay questions. Especially when there's four on a midterm you...

I need some advise. My parents want me to go into engineering. For the most part(still undecided) I prefer physics(especially theoritical). They don't think I can find a job with a physics degree. At least not without a PhD(they have heard certain companies pay engineers to get a PhD). Keep in...

Well finals just finished and I am pretty sure that I did pretty well over all except for my Honors Physics II course. I wanted to get advice about this. My final grade for the semester just came in for Physics II and its a C+. I thought I was going to do worse but the scale greatly helped...

First and foremost I'm a newbie on here and just registered today but have been visiting for a while and find a lot of you guys very helpful. I registed because I wanted some advice on my current situation. I am an EE student who went to Community College for the first year and half and...

Dear all Hopefully this is an appropriate topic for this forum. I am an assistant professor of physics in a liberal arts college. I have had, and for the first time, supervised a senior thesis involving a calculation in supergravity. Although the calculation was original, in the sense that it...

Is the student not correctly taught if the intructor says: the photon has no rest mass but it has a m=E/cc dynamic mass? Could such a statement have missleading consequences?

I don't get it "But his mathematical feat won the praise of others, including the math and computer science teacher who got Gaurav interested in it." Why is this considered a "mathematical feat"? He's not actually doing any math. I admit it's an awesome bit of memorization and recitation...
