Am I chasing something impossible? Heya, I am a 21 year old female who is so confused as with what to do! I'll give a bit of a background so someone can help me a bit more. Sorry it may be a bit long, but just bare with me. When I was young at high school I was deadset on becoming an...

They seem to be a total scam based on, if you notice they offer Trigonometry at one school and it takes 4 weeks to complete, however the normal semester is 18 weeks long. So when you enroll in the course, the teacher is only "required" to teach a certain amount of material, if you take the exact...

Can someone recommend me a 2nd year linear algebra textbook that is good for self-learning? The course is linear methods II and the topics are: Vector spaces, subspaces, independence, basis and dimension, row and column space of a matrix, rank, applications. Linear transformations...

Hi, (this is my first post! : D ) I'm a freshman in college. I came in wanting to major in physics and English. I soon tossed english aside and immersed myself in the sciences(during like the first month). I took Physics 1(general overview course touched upon all topics of physics from...

I always wanted to make a post about this, because it's kind of cool. Living in south Louisiana, hunting/trapping/fishing is a big part of the culture. This January, my dad's brother and his son were on a deer stand on a pipeline, and they saw a whitetail that was about 500 yards away...

Does anyone know where i can get a nice table of the amount of CO2 produced for each year with the corrosponding average global temperature?

What should you expect as a physics major when you first enter college? Is there some resemblance in academics from high school classes?

Hello, I am an extremely curious first year student, who is hoping to get a summer research position. Earlier on in the year, I had a successful interview with a professor of General Relativity, whose grad lectures I had been attending. By "successful," I mean he said I could join his reading...

I'm currently a sophomore at NYU. This semester I've been taking some pretty hard classes (Functional Analysis being the hardest). I'm probably not going to do so well grade-wise - probably a few B's. Basically, I want to understand as much mathematics as I can before I start graduate school...

I am currently working on revision and the following question came up: Find the integral of: \int x^2 \sqrt{x-5}dx now the way I went about solving this was to let u = x-5 and du = dx so that for the first step i got: \int x^2 U^1/2 du. I felt wrong right from the get go and had a look at...

Hey all, I'm at a crossroads and feeling really stressed out. Below are my options: a) Complete a BSc in Physics, 4 - year Honours: It will take me two more years of intense work. I am already on my fourth year of the degree but messed everything up by taking only one course my second...

(For engineering / math classes) at some of the 4 year colleges, (in California or anywhere really,) what is the semester usually like as far as review days before tests, study guides for exams and tests, and quizzes? Do the teachers provide any of the above? And also, do you usually have...

Referring to any kind of engineering, pick your favorite? But, how many semesters at a 4 year college does it take to get a Bachelors degree in engineering? After you take your prep classes at a 2 year college for engineering, then how many semesters will it probably take to finish studying...

I'm an international student who has been in the US for a long time. I go to a state college that excels in engineering, but it's mainly focused on industry. My major is chem e, and I'm still trying to decide between industry and grad school. My gut tells me I'm a better fit for grad school, but...

So I pretty much only got into my "fallback" schools. Also, I just heard from my friend who's getting his PhD in physics from SUNY Albany that he applied to 20 postdoc positions, and only heard rejections back from 4 of them. He speculated that he got passed up because all the schools were...

I'm in year twelve (in New Zealand, equivalent to 11th grade I think) and physics this year seems much harder than it was before. I usually got the equivalent of B's in physics last year, so I wasn't particularly great, and I want to get more A's this year (as eventually I want to be a...

Recall that the bending moment, M, at a distance, x meters, from the fixed end of a cantilever beam is given in terms of the second derivative of the deflection, y, of the beam. Determine the deflection,y, of the beam at the free end of the beam. Assume that the beam is perpendicular to the wall...

I've heard a lot that 2nd year physics is the hardest part of the major. What makes it so hard relatively speaking? Is it b/c most students are taking physics courses concurrent with a Mathematical Methods of Physics I/II class? Would one be better prepared if one were to knock those 2 out of...

Hey guys, so I'm a freshman and course registration for next year is coming up. I have several thoughts about what to take but I'm not exactly sure what would be best. It's spring break right now for us and I'm going to talk to the undergrad physics advisor in two weeks, but I thought maybe I...
