This doesn't seem to be a typical type of question for this site, but I need help choosing a topic for a literature review in an advanced writing class. It needs to be related to computer or electrical engineering, and is described as follows: "A literature review is a very common genre of...

Homework Statement There is one thing I'm not getting in this problem. It's about uniformly magnetized sphere. In solving the problem with formula for magnetic potential: \phi_M=-\nabla\cdot\int\frac{\vec{M}}{|\vec{r}-\vec{r}'|}d^3r' At one point a change of variable for...

Recently, I was discussing airfoils with a friend. I thought I was being clever and said "No, Bernoulli's Law isn't what's keeping it in the air - that's a fallacy. If it were Bernoulli's Law keeping it in the air, then airplanes would not be able to fly upside down. What keeps a plane in the...

I'm not sure if this really constitutes as homework, its really a question more about topics in physics. As a final project in our high school physics course, we have been asked to design and test a physics principle learned over the period of the course. Topic from Kinematics and dynamics...

I am in my second year of an undergrad degree in physics and we have to write a 2000-3000 word essay on a topic of our choice. This can be any aspect of physics or anything related to physics with sufficient physics content and should be written in a popular science style. My problem is I...

I wonder how does the topic you choose to specalise in during your PhD affect what you'll research later on in your postdoc years? I mean assuming you specalise in number theory and decide you want to change to geometry or analysis in postdoc who would even give you a job if your'e not...

I have three questions: 1. Suppose your supervisor has given you freedom to choose topic of research (for PhD). How do you decide what topic to work on? 2. Can one work on two somewhat disconnected topics and write about both in same thesis? 3. When do you feel that you have done enough...

urgent and difficult algebra problem with unknown topic due in 13 hrs due now

For our astrophysics class, we're asked to present to the class our research on a certain aspect of astrophysics/astronomy integrated with a relevant discipline of science (Students in comp. sci might choose to do a project on computer modeling of stars for example). I'm looking for topic...

I'm just interested into what part of the class people have trouble with. Of course people are different so the answer may vary but I'm talking in general here. Which topic was the hardest to grasp and solve for your class and yourself. Just curious to see where the bumps may be and if I...

I've been wanting to write a journal article for quite some time. It doesn't have to be anything major, but I'd love to learn the process first-hand. The most important thing is finding something that hasn't been done before, or an idea that hasn't been pursued. I'm finding a lot of trouble...

I need to write 3-5 paragraph for a topic about science, non-science reported like science , or pseudoscience. I want to know if Organic food is a topic for pseudoscience? If so, what should I write about? I want to write how healthy organic food are, better tasting, chemical-free, etc. This...

Hello, I don't have a HW problem to post (yet) but I have just started taking college level Linear Algebra and was wondering what most people consider the most difficult topics in the course? At this point I am up to solving for systems of many variables (usually 3) by performing row...

Homework Statement Pions have a half-life, at rest, of 1.77 x 10-8 s. A collimated beam of pions leave an accelerator at 0.95c. What distance from the accelerator will the intensity be half? Homework Equations The Attempt at a Solution as you can probably tell from the title I really need...

Another free fall topic :) Here I don't really know where to start Homework Statement A body in free fall covers 64% of the total distance fallen in the last second. From what height did it fall? Homework Equations y= y1 + y2, where y1=0,36y and y2=0,64y y=.5at², where a=g=9.8...

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...

Hey guys! When I was on a trip in Cambridge I took a picture of the famous apple tree, that is supposed (so the turist office claims:-p) to be the one, where Isaac Newton got the idea for his most importaint work. In the back there are two windows and one of them (I think it's the right one)...

Hi everyone: I am new to PCB design, I want to how know often do you use autoroute, or just route the trace manually. Someone tell me that, they route most of the traces automatically and then modify it manually. Thanks

Homework Statement ^Not quite relevant to follow the template, unfortunately. I need to do an investigation in Physics (not just a research paper) and I need help finding a suitable topic Some of the good ones that have been done so far mainly involved looking at the aerodynamics of aeroplanes...

Didn't really think this question fit the Homework section, so I hope this is alright. I need to have 3 sources "for" and 3 sources "against". The difficulty lies in choosing a subject that when I present the evidence for each side, ppl in class and the prof's eyes don't start to glaze over...

Hey guys, I'm completely new to these forums, but I'm hoping someone here can help me out. I'm a Junior in high school, and I basically need some help with the 7 page research paper I'll have to write. I love physics in general, mostly quantum physics, particle physics, theories of...

Hey guys, I need some opinions. I'm doing a project this semester for my chemistry course, and I was thinking about doing it on the contributions of ancient alchemy (or rather the work of alchemists, not just the transformation of lead to gold) to modern chemistry. I have to find a creative...

Hey everyone, New to the forum - I apologize if you already get heaps of posts like these... Im in Year 12 Physics, and out first assessment piece is related to the physics of sport. It's a typical physics project -> hypothesis, testing, report...etc We're looking at anything relating to...

I am surprised no one made at least one thread about this today.

How wise is it to make your Ph.D. topic on something that can be disproven experimentally maybe in a year or two? I tried to make this question as general as possible, so that it can apply to others who have the same question. Specifically, if I do some calculations or theoretical work in...

Which topic to pick for physics coursework??!? For our physics coursework we can choose any topic around physics to talk about and I am stuck on which one to do. A good topic will be one that I can link many other aspects of physics to it, for example quantum or something else. Previous done...

Hey, I'm a high school student interested in persuing Physics in college. I just took my AP Physics exam, and I think it went well =]. I realize this isn't a specific homework question, but because it pertains to my AP Physics class I thought it would be appropriate here. Because we took...
