Introduction Definition and 860 Threads

Hi, I have always been presented with a description of photons (and electrons more recently) as being entities that at times behave like waves and at times like particles (and I understant that typically particle is a substitude word for small little solid object of mass). So I would like to...

This is a very fundamental question. I apologize for its simplicity. I did searches on the web but could not find a clear explanation. Whenever I read about the principles of quantum physics, I always come across a statement along the lines of: "electromagnetic energy could be emitted only in...

I have a gazillion questions and I love feedback positive or otherwise as long as it is constructive and on point. I am not allowed to ask any at the moment- Bites nail in despair, but I am here to say a few words about me- First off I am wildly immature for my age which is half a tree by...

Greetings. It's my pleasure to introduce my self..well, I'm Ayran Thane Olckers born and raised in South Africa, Currently living in the UK. I am not new per say, however I never introduced myself on the forums. I am currently studying a BSc Natural Sciences at Open University, pursuing my...

Hello ,guys ! Nice to meet you in the forum .I like reading ,climbing and making friends. I hope to make more friends here !

Hi, my name is Aaron and I am a fourth year Applied physics undergrad in Ireland. I am studying DFT-D for my final year project and hope to continue on to become a postgraduate next year. My interests lie in condensed matter, computational physics and optical microscopy.

Hi, I studied 'A' level physics back in the '80s, my dad was a physics teacher, and I have an ongoing interest in the subject. I'm particularly interested in optics. The main thing that I remember being taught incorrectly at school is that white light is a combination of red, green, and blue...

What are the essentials to starting on this topic from the very beginning? What are topics I should have covered before starting? Suggestions please? Thank you.

My name is Marc. I live in Belgium and have graduated as a chemical engineer in 1991. I have had a broad interest in anything related to engieneering and physics, but must admit that I have forgotten a lot since I graduated.

I came across this forum after doing a Google search. I ended up in the biology and medicine section which I found interesting. I decided to sign up since it seems like a good forum to learn and have intelligent discussion.

Hello! I'm Reece, an aspiring Doctor and Surgeon (hence the "Dr." in my nickname). I am 16 studying 5 AS levels which are: Biology, Chemistry, Physics, Mathematics with Statistics, Further Maths. I have also studied and still study other subjects unofficially for my own interest, those being...

I really like physics, but I struggle sometimes and have found threads from here helpful in the past, so I finally registered. I hope to be able to help others and get help as I progress in my classes! Nice to meet you all, I go by Mel.

Hello, I am The Darkness. I don't expect to be extremely active, but I will asks questions every so often. Have a good time.

Greetings! My name is Emma Watson. I am From USA. I am Editor at The New Time Magazine. I plan to do some research in Physics. I look forward in participating with this society and share some valuable topics with other members. Thanks Emma Watson

I'm a secondary school student and that is my last year so it's an important one , I hope I go to Cairo University and graduate from it as an engineer .

Hi, handsome jack here. Fresh aircraft maintenance and technology grad student. Hope to learn a lot here

First, I have a question regarding the conservation of probability. The book shows (quite elegantly) that $$ \frac {d}{dt} \int_{-\infty}^{\infty} |\Psi (x, t)|^2dx = \frac {i\hbar}{2m} \Big{(}\Psi ^* \frac{\partial \Psi}{\partial x} - \frac{\partial \Psi ^*}{\partial x} \Big{)} \Big...

Hi guys newly registered member here, looking forward to working with you all!

Hello, Engineer looking to join a forum of like minded individuals. -Katrina

Hi PF! I'm Zephyr007 and I am 14 years old. I love to study Science since it has a lot of things to explore. I also love to test new experiments and debate in a specific topic. The area in Science that I love to talk about is Physics. I hope I could help you in contributing what I know and have...

Hello, everyone! I've lurked around for **years** before even making an account! Being a sophomore, studying physics and astronomy, I'm still so new. I'm so excited for the semester to start. Thanks for all of the wisdom. Miss Carraway

Hi everyone. I'm a sophomore now , majoring in astronomy, and will become junior in no more than 1 month. I have a good command of classical electrodynamics and quantum mechanics. However, I'm confronted with some problems. 1. I want to know more about Astronomy. I borrow Very High Energy...

I am looking for a short pedagogical introduction to Young-tableaux and weight diagrams and the relationship between them, which contains many detailled and worked out examples of how these methods are applied in physics, such as in the context of the standard model and beyond for example. I am...

Hi, I'm Jerry, a 74 year old retired engineer. Although my degree is in electrical engineering my approach to problems has generally been from the applied physics standpoint. I have recently become interested in space flight methods. Lots of Newtonian physics there! I ran across this forum when...

Does anyone know of any gentle, introductory books to LA that assume little prerequisites, even in the way of vectors and matrices? I want something that will give intuition and reasonable proofs, and will provide enough background for something like computational neuroscience. I do not know...

I want to read some books on the major different fields(solid state,computational and any other except from medical physics and the astro,theoretical,cosmo stuff) in order to get a feel for what I might want to pursue later on my degree.I don't want it to be a textbook as you might agree...

Hello, I am major in physics in the university. Physics is the thing which fascinates me a lot. After I touched the beauty of general relativity, I found that I cannot have a day without physics. However, physics is such a difficult and confusing subject that I often meet some obstacles and have...

It's awful, the reading of this first chapter is extremely boring, he appears only to cover divergence and convergence of series, should i skip this chapter?

I'm about to enter college as an Electrical Engineering student, but I am considering changing my major to physics. Before I commit, however, I would like to take an advanced physics course (QM, Classical Mechanics II, Thermodynamics, etc.) so that I can get a feel for the mathematical rigor of...

I'm aware that most modern textbooks gloss over relativistic qm and jump to qft. Since I'm not that brilliant of a student I'm thinking that i should firstly familiarize myself with relativistic and then go to qft. So my first question: Is it worth it to study relativistic qm or should i jump...

[Mentor's Note: Thread moved from the New Member Introduction to General Physics] what are the physical interpertation of entropy?

Hello, Physics Forums. I'm a new member to these forums. When the school year starts again, I'm going to be a freshman in high school. I'm mostly an autodidact due to my dissatisfaction with my past school's learning pace, disinterest, and due to various funding costs for higher learning. My...

Can someone recommend me a modern physics book, that includes introduction to all the different theories like quantum mechanics,quantum field theory,special relativity,general relativity,standard model,string,m-theory,supersymmetry,superstrings,quantum gravity,loop quantum gravity etc(if I...
