I currently have all credits completed for a B.S. in Biochemistry from the department of Biology at a top 50 university with a 3.2 GPA. I'm staying this last year to finish my few remaining GE requirements. However, I am deeply dissatisfied with my degree. I've spoken to other biological...

Hi PF members. I'm a first year engineering student, and recently got my midterms back and was highly disappointed with the statics mark, 55% compared to the class average of 23.8/40, SD 9.1. I did a very large amount of practice from Hibbeler's Statics textbook, 12e, but it seemed that the...

Hi, Am new on this forum.I am about to start my final year in electronics and telecommunication and i am planning for my final year project a research on how traffic (signaling) in a specific cell in a cellular network can be sent to another cell when there is a huge congestion like in a...

[FONT="Palatino Linotype"]Hi, I haven't done physics since year 10, and will be doing physics next year at college, it is involving the concepts i will list below, with a emphasis on the physics of the human body with them, so if it involves this it'll be great. I want a book that has...

Hi, i am a first year engineering student at the university of regina in cananda. I just have a couple questions to ask some other more senior engineer people. First off, how active are these forums? And, are there other, more active forums geared towards engineering i should check out? What...

Homework Statement An ion thruster may be used to change the speed of a satellite, through the emmisions of charged particles. Positive xenons ions are accelerated by the potential difference(deltaV) in the region between grid A and grid B as they move towards the right of the diagram...

I am in year 10 and I am very interested in physics, but I came up researching on this topic of acceleration due to gravity, but when I looked this question 'accelaration due to gravity is 9.81ms-2. what is the value in imperial units (ft.s-2)' I really wanted to work it out so badly. Could...

So, a friend just picked up an antique chemistry set from the 50s, containing all sorts of interesting stuff - among it sodium ferrocyanide. Out of curiosity, can this photodecompose or react with an acid such as HCl or H2SO4 to produce hydrogen cyanide? Any risk of cracking it open without...

This is an absolutely brilliant movie that every should try to watch: The movie tells the tale of a Quantum Physicist in the year 2092 who is of the age of 138. He is the last living mortal (everyone else has become immortal due to Telomeres regeneration) whom suffers from "memory...

Here is the problem that I am having trouble with (It probably is a no brainer, but i am a bit rusty- not a bit actually, a lot!). Here is the question: A student stands at the top of a building to perform a kinematics experiment. He throws a red ball directly upwards with an initial speed...

I am a senior Physics/Math major. I want to go to grad school (99% sure) but I am not ready to start immediately after undergrad, I hope to bike to and live in South America next year. My question is, how harmful will this be to my chances at getting into a top tier physics Pd.D. program the...

let me start by saying that i love physics and i am very passionate about becoming an astrophysicist, but this semester i am taking my first e&m class and for the first time it my life i actually feel like i am confused (i might add that i am understanding it more than a majority my other...

I'm only about a month into freshman year at college, but everything has been going great so far. I resurrected SPS at my school and am about to start some research with my professor on scientific reasoning and optics, which will hopefully get published when we finish. My classes are going good...

Analytical definitions vs intuitive (or perhaps "first year") definitions I just began my real analysis course in college and we were given an assignment; a bunch of mathematical terms for us to define. We are asked to define them using two textbooks, one, our first year calculus textbook, the...

As the title says, I'm a first year university student, currently attending Northern Michigan University. I'm really quite unsure about what classes I should take in my second semester and was wondering if anyone had some suggestions. I'm unsure what kind of physics/mathematics I want to get...

I understand that there are different meteor showers at different times of year, and that they are named for the constellation from which the meteors seems to come from (to an Earth-based observer). Does the point of "exit" for arbitrary meteors all year follow a pattern or a great circle on the...

I just finished precalc and have done a little bit of studying this summer of basic calculus. I don't know what is on the calculus ab/bc curriculum so could anyone here who has taken the class before tell me what I am missing? Here is what I have done so far in calculus over the past...

Season is almost over, so did you go on vacation, or?.. http://abcnews.go.com/Travel/americans-refuse-vacation-days-lag-rest-world/story?id=11361600

Hi all, I'm in an M.S. physics program, and am about to graduate May 2011. I do not have anything published yet, despite a summer's worth of research (which was very slow-going!). I want to be a theoretical physicist... a competitive field. So: I need extra time to publish something ebfore I go...

Hey guys, Totally new to the forum, but I have been studying physics since the age of 16. I graduated at 16 from high school and applied to several colleges, I was accepted to a few awesome colleges, but because of my financial situation at the time, was unable to go to college. I since then...

Let me explain my situation in short terms. 1. to get a degree here(malaysia), we'll need to work on an undergraduate final year project which is sort of alike thesis? basically an undergraduate research program. 2. I like theoretical or computational physics. Well, perhaps the math, quantum...

Hi, I will be a 2nd year EE student as of next september and I need to choose a stream (I am in a 3 year program and I'm from europe). There are 3 main streams but I already ruled the Electrical Power stream out as it doesn't seem for me. The 2 streams left are the Electronics stream and the...

Hello there, I am currently 14 and 1 and a half weeks away from starting high school and over my summer break I've developed a strong fascination in theoretical physics, especially in the brane theory(which involves the notion that there are actually 11 dimensions of space and one of time) and I...

It's a big goal, I know. I'm going to a top-20 in its field undergrad school (for chemical engineering). It's a state school in my state, but a solid school nonetheless. I wasn't the best student in high school. I say that after graduating 3rd in my class, but in all honesty, I didn't...

So I just completed my first year of Physics at my university. It could have gone a lot better, but I got sick with Crohn's and that really screwed things up. I'm not sure if physics is right for me, so I need input. The thing that makes me really question my self is that all the other physics...

1. My school's divided into 4 terms per year. 2. I decided to rack up on math completely for the first year. To begin with, I'm told that no one can decide for me what's the best way to arrange my schedule, I just know I'd hate taking a physics course and its prerequisite concurrently. Also...

Hello all Next year I will be attending college for engineering (top 10 nationally). At the orientation they said that the average GPA of the freshman class at the end of the first year is a 2.9 (this is quite alarming to someone who is used to getting A's). When I asked the peer advisors how...

Hello, I just finished school and I want to study physics, but I have to wait about 1.5 years until I can start with it. What would you recommend to stay in touch with physics during that time? Reading books would be the thing I came up with, would you say that reading in forums like this...

If Astronomers stated that they had using the Hubble telescope found a remote island on the Earth with 1000 meter tall Homo sapiens we would based on scientific knowledge and logic concerning the biological limits of animal structure (any land based animal that moves on the surface of the earth)...

hello everybody, I am going into my 3rd year as an EE major, usually between semesters ill either prep or try to learn more tools for my tool box. my question is this: are there any tools (languages, certifications, subjects, etc.) that would "really" aid me when i enter the workforce...

Hello Everyone! I too am a new member in this forum. I would like to thank Karkas for starting a thread on a topic, I spent the chief of today looking for on the internet, but, without much success. I too am a 16 year old, and my interests are somewhat similar to Karkas's with an addition...

So I was planning on getting into research next year for my Undergrad in Physics and so I self studied, trying to get ahead in my classes. I talked to my counciler about it and she told me to just talk to one of the professors. During Mid-Semester I talked to my quantum professor as well as...

Hi I'm a sophomore and I'm barely getting into research now. I plan to do an REU next summer , Junior year, and one after that, Senior year. Do grad schools even get to look at what you did Senior year summer? If so, that would mean we basically only have 3 summers to do research. freshman...

Hi, I am an EE student and I'm nearing the end of my first year from a 3 year course. I am quite sure that I want to continue studying after I obtain my degree, however I'm not sure what I want to study just yet. Is this normal for someone at my stage? Or should I already have a clear picture...
