Theoretical physicist... I'm an A-level student...i want to be a theoretical physicist...what am i supposed to do right now...can anyone guide me...i know i should have been a bit specific while asking this...but i want to have a general guidence for it...!...thanks for any kind of help...

The news always depicts them as real http://www.bbc.co.uk/news/science-environment-13964767 But as far as I gather from reading this forum and wikipedia, black holes are always said to be "candidates" Has it been proven "beyond a reasonable doubt" that they exist?

Theoretical situation: Temperatures at a point near the center of a gas giant of another star system have been artificially raised by local ET intelligence in order to achieve the heat to begin the fusion process. The planet has enough internal pressure to sustain the fusion process and it...

in projectile motion, why the experimental results are different with theoretical result? thank you

If so, what software are the likely to use?

So I have a problem. I have a measurement of several different points and I would like to compare that to the theoretical function. I'm not expert in origin. I've tried with simulated curve, but I cannot get the points and curve on the same graph :\ How can I do that? Thanks...

Their most highly-cited papers (of people like Yang, Oppenheimer, Teller, Feynman, etc.) are surprisingly readable. And they're *really* deep. They're highly cited for both of those reasons, after all. But no one seems to touch them anymore. http://prola.aps.org/abstract/PR/v73/i7/p801_1 -...

"Electric charge is a theoretical given . . ." Hi, folks. First, I'd like to say that although I plan to major in physics next semester, I know very little of it now. My lack of posts doesn't reflect how often I frequent this forum, though. While browsing a thread asking what "charge" is, I...

[During the pilot phase in one of the hospitals, a coronary-care-unit nurse reported a veridical out-ofbody experience of a resuscitated patient: “During a night shift an ambulance brings in a 44- year-old cyanotic, comatose man into the coronary care unit. He had been found about an hour...

So there's this guy that's trying to downplay me saying i don't have the smarts for math. I tell him that if you're prepare to work for it, then you can eventually get it. If you do anything consistently, you can only get better right? So I'm in need of assurance and prove to him that this is true.

Im a college student with a good knowledge of basic physics. I am majoring in math (unfortunately) but I spend all of my spare time researching physics. I have a lot of ideas for physics inventions but no physics experts to talk with because I don't know any of the professors. When I email...

As I understand it, the days of paper and pencil are mostly over. So what exactly do computational physicists do that that makes them different from theoretical physicists?

As many may know, the UC system recently released all of their admission decisions. I was able to get into UCSD, UCSB, and UC Davis, each with the physics major. I want to do theoretical physics (as the title states), or something involving applied mathematics and physics. My interest lies with...

dear all, I'm a second yr Math/Physics student in an alright UK university. Not oxbridge though. I am interested in pursuing theoretical physics (knowing it's competitive subject, and mathematically challenging) I have got high first in the first yr (hopefully well among top 5% of class)...

Hey I didnt know where to put this so the masters projects we can do for next year came out .. but I am not really interested in any of them However we can propose projects So i was thinking if anyone could lead me in the right direction Im want something in either COSMOLOGY or THEORETICAL...

Hello This is my first post and i was wondering is their a possible field know as applied theoretical physics? i am very interested in both applied physics and theoretical physics but i want them to be combined. this is taken into consideration that in college i want to double major with...

I was thinking about this today: When a force acts on an object, the object exerts on equal and opposite force - Newton's third law. Imagine this situation: I am breaking down a wall with a hammer. I begin hitting the wall gently and this wall doesn't break. I then hit harder and the force...

Homework Statement I'm in a physics 2 (electricity and magnetism) course, and I'm having trouble with something the professor discussed in class. I tried approaching him about it afterwards, but it still didn't make sense to me. I really think he made a mistake here, and I'd like input...

Let me preface this by saying that I have very little knowledge (basically zero) about astrophysics, just like to learn, have been reading some Hawking and have a question. I was reading about formation of universes and stars imploding, exploding etc.. the miracle of life in star form. I was...

Which "advanced" math courses are needed to prepare for graduate theoretical physics? I am a first year physics student preparing my schedule for next year. I would greatly appreciate advice on what kind of math will help me prepare for graduate studies in theoretical physics. Here is a list of...

Hi all, I need some help finding the thoeretical data rates for 802.11 a, b, g, n standards. I think I should use the following equation... C = 2Blog2M C = data rate in bps, B = channel bandwidth in hz, M = # of voltage levels or # signal elements For instance I look up the channel...

(I haven't actually got a degree yet, I'm just wondering if it's a risk doing the degree, in case I can't get a job) What are some jobs I could get into with a B.Sc in Physics? Where could I work? I'm really interested in finding out how we got here and why the universe is why it is.

Is there any "best" place (by place, I mean country or university or organization, whatever) for theoretical physicists? Is there advantage of doing research in a developed country like US to a developing country like India? If yes, what are they? Thanks!

I'm studying for a Theoretical Physics degree in the UK, and I have to decide this year if I should stick with that or switch over to a Joint Degree in Maths/Physics. So far, in Maths, I've done calculus up to multivariable and vector calculus, linear algebra, intro do real analysis, intro to...

Is it common to find the "applied" explanations more confusing than the "theoretical" Is it common to find the "applied" explanations more confusing than the "theoretical" ones? E.g. thermodynamics seems VERY confusing if I try to learn it from engineering textbooks, but VERY understandable...

I hope to apply for a Ph.D. place in 2012; is it possible to send off written papers [as if to write extended articles] as part of the application, to demonstrate competence? I am worried that otherwise the grades for the various modules of my Physics degree that won't end up as my intended...

What are the difference? What does each one specialize in? I've tried looking on google but I can't really find anything that explains exactly what they do.

do you khow definintion of theoretical physics? in this branch of physics; what skills should we have?

OK guys Can anyone tell me some hot research problems in theoretical quantum optics/cavity QED right now ?

I really like physics, and I really like engineering. I like theory and I like building things and understanding how things work and all that jazz. So it's always been a tossup, hence I'm working on 2 BS degrees in Physics and EE ( the reason is because i couldn't imagine not doing either...

What is it? By that I mean what does it consist of? My understanding is that experimental physics research is performing experiments and recording observations, then drawing conclusion from that. Is theoretical physics research then just locking yourself in a room and posing problems...

Hi. I'm currently a 4th year phd student in astrophysics, studying compact stars. I'm from China and am now an exchange student in US. What I'm asking is: if I really have more interest in theoretical physics, do I still have a chance of entering the field? I'm now in a very confusing stage...

Right so I'm a math major but what I really want to be is a theoretical physicist. 3rd and 4th year is when everything gets very specified, and I'm wondering which of the following modules would be most useful for that path? Here are the modules. Only 6 can be chosen from each term...

I'm thinking of doing a PhD in http://www.ucl.ac.uk/chemistry/vacancies/adverts/studentships/2011/Zwijnenburg_2011_1" . I come from a physics background and have a MSci Mathematical Physics. I'm confident that this PhD is suitable for me, and all I have to do now is accept the offer, but I...

Hello everyone. I'm a 11th grader who plans on becoming a theoretical physicist. In fact, for most of the time, the only thing that goes in my head is trying to think of an idea to find a better alternative to quantum mechanics, as I feel that it is not in accordance with nature. I have the...

Is it mostly trying to coming up with equations, solving them, reading etc.? Do they use computers a lot or can the work they do be done simply with a pen and paper?

How is "Mechanics; a course of theoretical physics volume 1", by Landau and lifshitz? I have recently bought Volume 2 of this series (the classical theory of fields) because it was recommending for an undergrad course I'm following. I was wondering how good this first part was. I'm mainly...
