Hi guys, I am trying to study GR on my own. You got any good books in mind?

OK, I want to self study classical EM in greater depth than my electromagnetics course, and I plan on working through Jackson (I am currently an undergrad). I want to get into the relativistic treatment of the subject. However, to properly tackle this, I feel my mathematics background is...

So, my present situation is that I dropped out of high school following the end of my junior year at the end of last year, got a GED, and am attending a community college this coming September. I took the AP calc and physics tests and did pretty well on them and I've been studying a linear...

Hi All, I was hoping someone could help point me in the right direction. I'm interested in simulations of General Relativity with generic mass distributions that are self gravitating, i.e. that the metric of the space-time being considered is dynamically altered by the distribution of mass whose...

This question is bugging me, and I think I need to get it answered before I move on to working on the "harder" problems. I hate being stumped by the little stuff like this. Anywas, I'm including the question that I have as an attachment, it will be easier for all. Thank you!

I came across this link and wonder if their is any factual basis: http://mindbluff.com/hypnotic.htm Thanks...

Over at the PSYCHE online journal they are having a discussion of Metzinger's theory of phenomenal consciousness and selfhood. Here is a link to his precis of this theory: http://psyche.cs.monash.edu.au/symposia/metzinger/precis.pdf I am going to copy a couple of paragraphs from this...

I'd like to expand a bit about a comment I did in the other subforum. I find it amusing that while Planck scale is a good cutoff for Gauge theories, it is not a good one for gravity? The point is that for a cutoff \Delta x in position space, we expect to use a cutoff \Delta p= \hbar /\Delta x...

Is it true that there are cases in which the radiation reaction force on an electron is nonzero even if its acceleration is constant? I am confused because the radiation reaction force is proportional to the time derivative of the acceleration. Also when considering the radiation reaction...

I am half way done with Physics 2. I don't feel that I learned enough and I want to review and relearn physics 1 and 2 during the summer. What is the best physics textbook, which is the most popular for freshman physics. Also, and most importantly, which is the best for self-learners? Thanks

Where to start self study of higher mathematics? I am a student who just finished high school and i am going to go to college this fall. I got like 7 months to shape up my maths and physics because my country got only 10 years of school. I want to ask if i could self study on all the advanced...

My teacher hasnt been in and I am trying to self teach this topic. Can anyone help me with this question, its probably quite simple but I am really stuck :redface: :frown: A flat circular coil of mean diameter 3.0cm has 500 turns and is situated so that the plane of the coil is perpendicular...

In this ever more dangerous world can you defend your self ? In the UK it is illegal to carry an offensive weapon of any kind, so i think it would be lucky to escape a gang of thugs. What are your ideas on getting out of such situations ?

I know there are several threads asking for textbook recommendations, but I need something special: I am teaching myself math, and need a Linear Algebra textbook from which I can learn on my own. I really want to obtain a thorough math education, and I'm almost done with calculus (Stewart's), so...

I'm asking from a mathematical aspect, please be as exact as possible. Suppose A is an observable, and B a Borel set in R (real numbers). Without further assumptions on A, I would like a general expression for the probability of measuring one of the values from B for A. The reason for my...

Can you explain why an idea is so dangerous that it must be suppressed? Specifically the concept that the Pauli exclusion principle may be able to explain why the self-gravitation of the quantum vacuum has not yet collapsed the diameter of the universe to a few thousand kilometers (and may be...

This question may have no value since it defeats itself. We can't use logic to discuss an illogical god. Nonetheless I would be interested in other peoples thoughts on the possibility of a "not-always-logical" god.

After an abortive start in the new IR Forum I am beginning a new thread on the published theory of Self Creation Cosmology. There has already been many posts on the subject in PF and I apologise for any repetition, but having been asked to post it here in A&C I here make a clean start! The...

SpaceTiger has created a very valuable thread on Mainstream Cosmology. For good scientific practice it is important to compare standard theories with testable alternatives, however ST's thread is not the place to do it. The theory of Self Creation Cosmology (SCC) presents itself as such a...

One has to provide an input to start an oscillation, but that input can be removed and the oscillation will continue. So when we talk about space time, if the original, "input", is no longer present we are looking at an effect and have to guess the cause. So could we work backwards...

Embargoed Book Claims Saudi Oil Infrastructure Rigged For Catastrophic Self Destruction By Huffington Post 05/10/05 "HP" - - According to a new book exclusively obtained by the Huffington Post, Saudi Arabia has crafted a plan to protect itself from a possible invasion or internal attack...

I have a job as a salesman in a store that gets maybe 5 customers a day if I'm lucky. No excessive chores (vacuum, clean bathrooms, takes maybe an hour all together), so I'm left with hours of time of not doing anything. So I figure (especially over the summer) that I might as well learn a...

I have copied over a statement from a JPL release regarding the "Trojan Moons", of Saturn. It is interesting to me that there is an automatic assumption of lifelessness on Saturn, even though there is Oxygen present. I do respect life, and I also respect the sovereignty of the other...

hello, i was wanting to teach myself multivariable calculus. i am currently in calculus BC AP. that class isn't challenging enough for me. do any of you out there know any good sites or good books for multivariable calculus. any help would be greatly apprecaited. thanks in advance.

hey, i really want to learn physics. however, I can't learn it in school yet. What are the best books for teaching yourself physics? p.s. I would eventually like to go into quantum, or another branch of theoetical physics. I'm not sure if this would influence the books I should start off...

Hello I have a query (Classical Electrodynamics) regarding Self Energy and Interaction Energy. I understand that the integral definition U_{tot} = \frac{1}{2}\int_{all space}k\epsilon_{0}E^2d\tau = \frac{1}{2}\int Vdq represents the total electrostatic potential energy of a system and...

If say, there is a false premise 'x'. Am i capable, psychologically, of convincing myself that this false premise 'x' is true? Therefore, can i cause myself to reach the point at which false premise 'x' becomes a true premise only in my private world? Is there a name for this?

This and any form of self mutilation is really amazing and baffling to me. I have seen videos of people from primitive African cultures who have their heads layed wide open - permanently - for regular trepanning "treatments"...

I would like to talk about the speed of light and how so many people, even physicists, don't realize that light speed relative to itself is in fact infinite. What I mean by this is if you travel at light speed you in fact travel at infinite velocity, not 300,000 km/s. Is there anyone here who...

Amit Goswami's "The Self Aware Universe" Hey everyone, I'm a new member, but have enjoyed reading threads here as a guest for a little while. Anways I just wanted to get some reflections on The Self Aware Universe by Amit Goswami. Here is a link to an interview with Prof. Goswami...

The universe is self aware because WE are self aware. If anyone argues this then I would then question as to how self ware THEY are.

So how do I show that when we have a linear second-order differential equation expressed in self adjoint form that the Wronskian W(y1,y2)= C/p(x) W=y1y2'-y1'y2, and C is a constant, and p is the coefficient where Ly=d^2/dx^2(pu) - d/dx(p1u) +p2u ? I know Ly1=0 and Ly2= 0 if that helps at all.

http://www.prweb.com/releases/2004/9/prwebxml159636.php This article disusses a project, in which the robot self-built , and self-programmed. How long before it turns us off? This is an old question, but with all the Rf in the air these days, how long before the singularity occurs where...

hey, i was just confused here, which is the right formula for finding the self inductance of a solenoid, given the number of turns, the cross-sectional area, the length, and the current. is it L = Uo x Ur x N^2 x A / L (Uo = mu o, Ur = mu r)?? pls if it is wrong, let me know the right...

Would it be possible to buy a trig textbook and read it straight through and teach myself? Do people do this? I know that it is very hard to teach yourself calculus, but isn't trig much easier to teach yourself?

hola. this year in high school i was enrolled in AP calculus. the year before we had an awesome teacher who was incredibly smart. this year, however, he left and we got a new teacher. it is her first year teaching this. consequently, she's not teaching well and id say 75% of the class dropped it...

http://www.math.com/students/wonders/life/life.html After reading this article, I thought it would be a good research project to do for a science competition I'm planning on entering. Is it something worth spending a year researching on? The thing that intrigues me is the possibility of...

Dear forum members, may I post on this Forum my questions about GR and a brief description and link to my work in which they are answered? Questions of General Relativity (Also posted on the Special and General Relativity Forum) 1. In the presence of gravitational fields the...

i have a paper on probabilities. What shld i do? i am in singapore. do i send for copyright or what sort of route i shld take.

Does self interest negate the positive effects of a country's actions? The USA is constantly claimed to be selfish, despite the result of 'selfish' acts being HIGHLY positive for others (The marshall plan is a great example). Currently, it could be argued that we would like to develop oil...

try to describe to me what a sense of self is?

Tuning our bodys up as musical instruments helps tune up the universe. Just like we can't expect to go traveling to other dimensions until we keep our minds above negativity (breaking commandments). We can't even be galactically until we tune up our attitudes, and what a blessed world this...

Those that follow my posts are well awear of how serious are my objections to the traditional physics. They must at some point question them self: How can the traditional physics be wrong despite all the progress mankind makes? The answer is simple: I can put A + B = RESULT They can put A + B...

What is so called SELF ENERGY? I know the explanation that it is the energy that a point charge has when it is by itself,at a large distance from other charges. In textbook (ohanian) says that it takes work to assemble the point charge out of infinitesimal pieces of charge.The energy needed to...

this is by no means polished. i will be working out my thoughts as i write. whenever i try to understand the concept of self, i visualize a tree. i am the tree but this physical me might only be a branch of the total me. the trunk is my core being(soul, spirit, etc?) and the big branches...

Is every human action motivated by self-interest? Even when we help a complete stranger do we do it becuase it makes us feel good (and hence we are doing it out of self interest)? What do you think?
