Hello all. My name is Stew. As the title says, I'm contemplating becoming an astronomer. I'm 23 and spent the last five years in the Navy. I'm out now and want to go to college. (I'm currently stuck in the field I had in the military because I have no other skill sets that will get me a job)...

Hello everyone, I'm Eric and I'm looking at Ph.D programs. Looking at MITs page (my dream school) I jotted down the classes I'd want. My questions are: 1.Is my list thorough enough?too thorough? 2.How many years will they take? 3.Dissertation ideas? The classes: Quantum Theory I+II...

Homework Statement Is the sequence {n} convergent? Homework Equations The Attempt at a Solution I believe that it is not convergent. I'm thinking that I could show this by a Proof by contradiction, but I am not certain. Am I going down the right route? Thanks.

Hi physicsforums, I'm a CS student in my first year. I enjoy programming and have liked my intro CS classes. However, I'm pretty depressed with the rest of college. I feel like I'm spending a lot of time reading through literary theory, rote memorizing humanities definitions, or memorizing...

I am currently a mechanical engineering student at a Canadian university and what I have experienced thus far is leaving a sour taste in my mouth. A year and a half in and the only lab I have is mechanical drawing, however, we don't even get to enjoy taking apart the objects we are drawing--we...

Hi, My name is Brad and I am a graduate electrical engineering student. Recently I wanted to go back and review and patch some holes in my head about fundamentals of physics. Therefore, I went back to my textbook Physics for Scientists and Engineers with Modern Physics by Serwey and Jewett...

Now I'm not a PMI (perpetual machine inventor). In fact I'm quite convinced that there is no such thing as that. But a while ago, I saw the schematics of a perpetual machine that is hard to debate. Well this is how the machine worked. The inventor argued that if you have two magnets as...

I need help with getting a girl out of my head. We worked together on a project at school and spent a lot of time together. She's extremely nice and she's pretty and I would want nothing more than to be with her. I have no idea how she feels about me, but it doesn't matter. She has a boyfriend...

Hi all, I am from electronics background, yet I have studied quantum mechanics. Lately I have been reading Prigogine I., "From being to becoming". (If I am correct) the book deals with the one directional nature of time as it flows from past to present and onwards to future. But I did not get...

Hey all, I am currently on a 3/2 degree program for physics and engineering, where I'll spend 3 years at one school, transfer for an additional 2 years and graduate with an engineering degree from the second school and a physics degree from the first school. So I decided I need to start...

I've been working on my 2 year transfer degree at the local community college in order to head to a 4 year for mechanical engineering. After a few chem classes (which are req'd for ME anyway), I find it really fascinating and kind of fun. I've started toying with the idea of switching to a...

I've been thinking about getting into something in Optics, but I don't know anything about the different courses and such. Anyone here have any suggestions or know a good source of info on getting into optics?

About my thinking ! Kenetic E" last week i am thinking about the kenetic energy of the Earth compared with the object that falling down . I assume that it may be equal to 0 or ∞ but no why ?? How about you for this case ?

Homework Statement 1. A grasshopper sitting on the number line can jump p or q inches right or left. Find all points on the line the grasshopper can reach starting from the origin (i.e. at zero). 2.Say exactly eight people show up to your birthday party, where there are two types of...

I was thinking about a rod colliding with an external wall, if you will, and began thinking what would happen if the collision was elastic (not sure if that is correct in this context, but simply the energy of the rod is the same before and after the collision.) I assume if a particle was normal...

what does health physics entail? I am interested in either nuclear engineering or Health physics but would like to get more detail on what it is that they actually do? Anybody know and want to help out?

It might just be finals getting to me, but what else can I do with a Bio degree besides med school and teach (which I don't really want to do)? I was thinking about it and it seems like a Chem or Biochem degree is way more valuable to industry? I'm sure (hoping) it's not true and I think I'm...

http://www.teacherschoice.com.au/maths_library/area%20and%20sa/area_2.htm "NOTE: The value of p can never be known exactly, so surface areas of spheres cannot be calculated exactly." p = pi here. It always irks when people say "(insert irrational constant here) doesn't have an exact...

I am currently in my third year of my geology degree which I am enjoying but I love physics too. I don't really want to be strictly a geologist after I graduate, more like a geophysicist as I've taken an interest in seismology after narrowly surviving the 2011 Christchurch quake while in New...

I came up with last night and I couldn't figure it out. Can you actually predict what happens in a collision? For instance, suppose a truck and a toy duck is coming from opposite ends, they both have a velocity, now suppose they crash, it should be obvious that the collison isn't going to...

An augmented matrix scaled by a number also means the solutions set is scaled by that same number. I believe this is true due to it basically being the same as elementary row operations preformed on each row. Unless it is a zero scalar in which case you lose all conditions. Is my method of...

Hello everyone, I'm thinking of getting in the the nuclear engineer field. I want to know if getting a degree in electrical or mechanical engineering first would help? I want to get a degree in one of these two first, but I don't know which one would transition better for nuclear...

(QUESTION:) I was Thinking of Creating a Generator System... Okay, so I've been thinking about creating a generator system that doesn't reply on a Ful powered engine and to eventually get off of the "grid' completely one day... Also, in the last 4.5 years since we've moved into this house...

I am doing my gcses and have to decide what A levels I want to do, which of course involves deciding what university course I would be aiming for(oh god the pun in there is terrible, lol) I enjoy and would like to do the following subjects for A level, Maths, w/ Further Maths if possible...

So i stared as Comp Sci major about 3 year ago, very quickly changed to EE since i got interested in robotics and stuff like that. Since then i been playing with electronics, doing a lot of robotics work and i really like it... and i think its a hobbie that matches with me 100%. But now that I...

I have very little background in physics and I only have basic calculus under my belt... but I can't seem to get this thought out of my head. There is no mathematical proofs here, no experimental evidence, not even any real evidence for theory, however I'd like to hear your thoughts on the...

Hi all, I'm new here and wanting some advice and this forum came up top in Google when I was hunting around for advice with regards to working in the Space industry. I'm 34, dropped out of university when I was 19 in the first year (was doing a Physics with Laser Application course at...

As the title says I want to go into Medical Physics. I have one more course requirement to finish my undergrad at the end of the spring semester. None of the courses are offered so I will have to do a independent study to replace one of these classes: Biophysics, Analytical Mechanics, or E&M II...

I'm looking for a bit of career guidance from you guys. I'm thinking about quitting my job and going back to school for some type of engineering. I finished a BS in chem in 2007 with a minor in math (through linear algebra and few upper electives) and a 3.1 gpa. After that I immediately...

Hello everyone. I would assume such a thread would be very common in this section but I believe my circumstances are specific so I will make a new one. I'm a student in Slovenia, Central Europe. I'm finishing a bachelor's degree in physics. My particular area of study were astronomy and...

I think I may have made a thread about this a long time ago but maybe I didn't. Does anyone else have things they do on a daily or hourly basis that occasionally embarrass you? Now, I'll give you an example of stuff I do that occasionally gets screwed up and makes me look stupid (to myself...

I need to think less about things. Thinking about things means that you have to think about the things that have to be done after those things are done. bla bla bla I lack the habituation. I always think. Think think think. Thinking about thinking. And thinking about how to think. Bla bla bla...

Hi, I am currently doing a major in mechanical engineering. I am starting my 3rd year now. After i finish my major I'm thinking of getting my masters in aerospace engineering. I think that is going to take me like 5 or 6 years till i finish both things. Afters my masters, I what to do a major, a...

First, I've almost decided that I want to be an electrical engineer, but I wanted to know this. First, as a former math major who is highly interested in signals processing, is that the right path for me? And then I got to thinking of how much money I'd need to make per year to support the way I...

Hey, although I am 14, i have known for a long time that i want to be a physicist. My dream job would be to work at the LHC or at fermilab. I was wandering what universities offer great physics courses in the UK and would be right for me. I have an IQ of 162, and enjoy maths and physics. What...

I want to design and make headphones and stuff like that. Is electrical the best way to do fun stuff such as that?

I have been thinking out of the box and I have come to the conclusion that something cannot exist without consuming something else. I know this sounds really wacky (for want of a better phrase :)) which is why I posted this in the Quantum forum, lol. We know plants consume nutrients and use...

I don't know enough physics to answer these questions myselfs. For all I know, they might be foolish. Is there a branch of physics that takes perspective into account. I use that word in its most basic sense. To an observer on the quantum level, might everything appear to work according to...

Hi, I'm new here, and was after some information and general advice on what I need to get done. For a very long time I've been extremely interested in astronomy, and as a child, and indeed as an adult, it's something that I've always wanted to do professionally. Unfortunately, I have a bit of...

If I'm thinking about this correctly, the voltage difference in a conductor between two points of unequal temperature occurs because the chemical potential is lower on the hotter side which causes electrons to bunch up there. Is this correct? So at equilibrium, the macroscopic observation is...

I need help starting and solving this problem. See attachment for problem.

I'm about to enter my sophomore year of chemE. I haven't taken any chemical engineering classes yet but am registered for one in the fall. In high school, I found chemistry incredibly interesting, math tolerable, and physics..well I had only read Carl Sagan and Stephen Hawking. Now that...

We all know that our universe is headed towards a heat death with maximum entropy and useless energy. However, we know that a vacuum of space will always have energy greater than its local minimum (potential well) due to the uncertainty principle. There must always be random fluctuations...

I am 15 years old living in the Uk and i plan to leave sixth form in two years time with A* A-Levels in Sociology, Physics, Further Maths, Maths, and Chemistry and AS in biology and General studies. I would then hope to go to Cambridge, Imperial college, or Edinburgh University to study Physics...

I'm studying math proofs and I can't seem to grasp the intuition behind various proofs. Does this mean I don't understand the mathematics behind it, even though I understand perfectly the logic? Is mathematics supposed to be intuitive? Edit: I know basic facts of logic is founded on reason...
