This is driving me nutty. Here's a theorem and its proof as appearing in my notes. It's short, go through it if you have the courage. :smile: Theorem. Let L=K\left(\alpha\right), and let \alpha_{1},...,\alpha_{n} be the n conjugates of \alpha . Then if f\left(x\right)\in K\left[x\right]...

Right I'm thinking of applying for a phD in some area of physics once I finished my 4 year Msc physics course, I'm going into my second year once this summer is over. Do you think I should be worrying about what topic area of physics I want to do a phD in already? (and I'm thinking of...

One interesting question, I believe to understand how questions can be asked and how they can be answered is "How does thinking work ?" Lets say I wanted to write a some some kind of computer program. For me that would normally be some program written under Linux. Let's say I log on to the...

My bro. told me that it feels good b/c it gives us a sense of accomplishment; legacy. But I saw an old video I havn't seen in a long time and it made my brain access a part of its mind which I don't experience very often. Thanks for the replies!

What is thinking, and why does people "think" ? How can it be that humans once started "thinking" ? What can "thinking" be used for ? How is thinking performed ? What can be thought of ? Is there different ways to perform "thinking" ? Is there any difference in quality in what way...

Relationships between thinking, logic and deductive reasoning .. I have to admit that philosophy is normally not "my thing" and that the reason that I found this wonderfull forum was that I was searching for something about physics and technology. My idea was/is to collect some central...

I don't understand one thing... the square of 1 = 1, the square of 2 = 4, the square of 3 = 9. Basically... a square is the number added to itself by the number of times it is. That is square of 2 is 2 added to itself 2 times.. so 4, and 3 added to itself 3 times makes it 9. Now take the...

Good day. I'm a 11th grade IB student and i need help thinking of a nice physics project. Could you guys recommend me any nice ones? Preferably ones that would take 2 weeks to a month since i need to complete a certain number of hours doing the project. I'd take into consideration any project...

In metal, fermi energy is the highest energy states that electron occupied at T=0. And so, fermi energy of a particular metal is an intrinsic value, and won't be changed. Then for a semiconductor, What is fermi energy, is there any concrete interpretation as of metal? Why is it just in the...

I'm doing this for extra credit for my teacher and I have NO IDEA where to get any problems. In the past, my friends did... something like a = b (long lines of equation) and we had to find what's wrong. It took a while, but the club got it. I want something like that. It can be at around...

I'll give three subjects to work with please tell me any descriptive attributes to them: Thinking: If you think with the knowledge you have now but expand on it does it help yourself? Also, how does learning have to do with this Learning: How do you know when your learning at your limit...

I am operating under the assumption that one must engage in thinking when studying the nature of thought. Conclusions about the nature of thought are thus distorted by the process used to reach those conclusions. Are we prepared to state that thought is a tool which can be trusted to...

I'd like some help from builders - modellers or mechanical tinkerers. I'm trying to build the skeletons of some polyhedra - the vertices are intersections of rods - no faces. http://www.reed.edu/~mcphailb/puzzles/images/hex.bmp" I want to be able to telescope the rods by about 3x. So, I...

If the Earth was flat, and there were no such thing as gravity, and it, along with all the celestial bodies, accelerated upwards (so, parallel to normal) at 1g(9.8m/s^2), what would happen if I dropped a pen while I am on earth?

I have a TI-83 graphing calculator and am thinking about upgrading to the 89 because extra useful features. Is it worth it?

OK I'm a big fan of lateral thinking puzzles, logic puzzes are great for testing those little grey cells and I thoroughlly enjoy them too, but when you want to get:confused: and a little of the beaten track: lateral is the way to go, so I found some. Have fun...:smile: Ok these aren't that...

As an undergraduate, did any of you know what you wanted to studied in graduate school. I have absolutely no idea what I want to studied once I begin graduate school. Was there something that caused you to go into a certain direction in a physics field. I guess most people get there...

So I've got an MSc in Engineering physics and I'm now deciding if I should go find a job in the industry, or stay in school to get a PhD, more specifically in Scientific computing and numerical analysis. Getting the PhD is very temping, but the main thing holding me back is that I don't know how...

Can anyone recommend some good 'introduction to critical thinking' books?

Hello everyone, another example in the book I'm wanting to make sure I'm seeing how they got their answer correctly. It says: Supppose the group pof 12 consists of 5 men and 7 women. How many 5 person teams contain at most one man? Solution: The set of teams containing at most one man...

Why do people think about extra dimensions to aide our knowledge of the universe, when we do not even know what forces control the elements? i mean what controls the properties of the photon, the electron, they are well known in the literature, but what gives them there properties, why should a...

I believe that time as humans perceive it, is a product of how often our conscious thought, or inner dialogue, accesses images of time passing. To illustrate this, consider a human watching the second hands move on a wall clock for 2 minutes straight. This person will feel like much time...

It's the annual chili cook off at work, and based on the sorry, pathetic entries last year, someone needs to show these people what real chili is. Real chili is not soupy nor does it contain bell peppers. Bell peppers are not what they're referring to when a chili recipe calls for peppers...

I can't seem to understand this problem. Could someone give me a hint as to what I'm supposed to be thinking? Vectors A, B and C satisfy the vecotr equation A + B = C, and their magnitudes are related by the scalar equation A^2 + B^2 = C^2. How is vector A oriented with respect to vector B...

Hi all, Considering the nature of a water wave, how is the coconut going to move inland, say it is in the middle of the ocean(pacific)? Am i correct to say that the coconut bobs straight up and down. Thx! Any help will be appreciated

Should i be able to replace those large stationary "dee" magnets with electromagntes? (or would that be a grand misuse of the powersupply, as i know i will need to supply an ample amount to the electron gun, and the current which i need to accelerate the particles, rather than simply keep them...

Ive noticed something about myself when i try to solve a problem consciously i can't do it i'd be stuck there for hours and then i'd give up and like a nagging song the problem would surface again and my mind would solve the problem effortlessly and everything starts to 'fit' like a jigsaw...

I have somehow managed to maintain a "B" in this class, but I need help on this assignment. I have completed it and just need to know if it is wrong and if it is why? Exercise 10 In the cartoon Doonesbury, the character of Boopsie claimed to be the reincarnated girl friend of the 16th...

Hey everyone. It's summer, and I'm thinking, mostly about superconductors for some reason, and I have a question. For this, I'm going to pretend we have a room temperature superconductor pulled into a wire (I know, doesn't exist, but just thinking here). If a DC voltage was applied to a...

The word dimesional may not be a good choice, but the idea is to consider how many thoughts [maybe levels of awareness] we can carry at once. The other day while driving down a long, straight, remote road that passes through the grass fields, I was playing a little mental game to see how many...

I don't know why, but lastly I can't control and stop my thinking. It's like my brain thinks against my will and I can't control it. I'm afraid that if I keep on like that, I will finally run out, and get some kind of brainy diesease like Alzhaimer or any others. I'm thinking even when I do...

Can you tell in a general sort of way what some is thinking ? this would be some what easier with a familly member or close friend, but what about a stranger ?

Can you elaborate on linear and picture thinking process. Linear as being a step-by-step process, and picture thinking processes multiples "pictures" simultaniously. Which thinking procecss might make the person smarter, successful?

We've all had those conversations... when you know you're right but the person you're arguing against is dead set against agreeing you no matter how manyc ontradictions you point out in their argument and they ignore or how illogical their views are. Now, feel free to contribue! Mind you, some...

Hello there, I'm by no means a philosophy student but I plan on majoring it in college :rolleyes:. Anyway, I was killing some time, waiting for my introductory books to arrive, by playing with my 8 year old little sister. Well, she asked me this very interesting question. "Phusicist, when a...

Before I even venture into the maze, a question: what I'm meaning to do, is post a 'personal theory about relativity' that some guy told me. Now, it's quite ludicrous, even though the dear man tries to stick to the right principle. Which makes it hard for me, who is not really interested in...

Einstein stated that the laws of physics are the same in all inertial reference frames. Lets do the old thought experiment There are a pair of twins each with identical watches. One remains on Earth while the other travels out into space near the speed of light and back again. The...

Suppose u have a perfectly healthy individual. Is it possible for him to think himself to death? Some ideas i had: For example by meditating so intensively that one feels the ego dissolve and consciousness leave the body. Another example is this part in the matrix where they say: "if you...

The following is not intended as a definitive explanation of other dimensions, but a suggestion for other ways of looking at the idea of physical dimensions. Supporters of string theory occasionally remark that the reason we cannot "see" other dimensions is that they must be very small...

Right now, along with many other high school students in North America (and the rest of the world, I guess), I am faced with the dilemma of what I’m going to do after high school, and subsequently, the rest of my life. I know that with my limited knowledge of the world outside of high school...

Hi, A homework problem I ran across awhile ago asked me to determine if a set of of 2x2 Matrices were a basis for the set of aa 2x2 matrices. Am I going to run into any pitfalls by thinking about such 2x2 matrices as vectors of 4 components? Basically what I did was turn each 2x2 matrix into...

Thinking "out of the box" Hey guys, I'm currently doing A levels (UK EXAMS) and I've decided I want to do physics at Uni... I was wondering if anyone could recommend me any books or websites to help me think "outside the box", ie. applying current knowledge to new situations.. I can do it in my...
