Hello everyone. =) In honor of Pi Day I'm going to be explaining the very beginning of set theory (which I consider the beginning of university math) live on Twitch in about two hours (1 PM GMT). For those who do not know Twitch, it's a completely free streaming platform - you can come in and...

Hello! My name is Parker, but you can call me Apex. I don’t really mind either way. I’m an 8th grader that is interested in physics and astrophysics. My favorite author is Michio Kaku and he inspires me to learn more. I’ve read two books by him so far. I hope that through this website I can...

Hi, I am an undergraduate student in the 3rd sem, we have Lagrangian Mechanics in our course but I am unable to follow it properly. Can you please suggest me a book that will introduce me to Lagrangian and Hamiltonian Mechanics and slowly teach me how to do problems. I am beginner, so please...

Summary:: Pretty sure they have something to do with path integrals, or what not. But obviously it's hard to *search* for this stuff. Basically, I'm looking for a textbook, any textbook--physics, mathematics, etc.--that deals with integrals that look something like this (mistakes are mine): S...

Should i read Introduction to Calculus and Analysis by Courant? I have calculus background I want to study multivariable and single variable in rigorous way There is a lot of books in this subject like Spivak, apstoal,Courant,... . I am not sure what to choose

Although Stokes Theorem says that the line integral of a closed surface equals to zero why do we get a non-zero value out of this question 1.11 (and figure 1.33) in the Griffits Introduction to Eletrodynamics Book?

I have a copy of Griffiths Introduction to Elementary Particles (1st Edition) and was thinking of beginning to work through it. I was curious if anyone knows if this text is sufficiently up to date or if there have been any major developments in particle physics that would make it worth getting...

Hey, PF! I am currently studying Algebra and Trig, and was wondering what's a good book to use to get eased into the process of proving statements and theorems. I'm planning to use Basic Mathematics by Lang but the proofs in it have been a real hindrance to my progress. Even just simple proofs...

Summary: A short introduction to a antique calculator that I recently got I first know about this thing when I was chatting with @jedishrfu a couple months ago, and I was fascinated by it. It functions like a soroban but looks way cooler and easier to carry around. Also, it is a important...

I am writing an introduction to a first course in elementary number theory. The topics are linear Diophantine equations, modular arithmetic including FLT and Euler's Generalization, quadratic residues and Non - linear Diophantine equations. How can I write an introduction to this showing linkage...

Hi guys, My name is TheGreatOneAD. I'm a 9th grader who would like to pursue a Ph.D. in Astrophysics or Theoretical Cosmology later in life and is in deep love with physics. For me, Physics is love and Physics is life.

I'm not really sure where to put this. I came across this nice article on Medium. “The 5 Basic Statistics Concepts Data Scientists Need to Know” by George Seif https://link.medium.com/APtnCOapOV

I like science, which is obvious if I'm on this forum. I mostly like biology but I dabble a little in everything. I like answering questions people have in introductory biology and chemistry. For my own interests, I mostly read about cellular ion channels, but I also read about integral membrane...

I have project about cooling the room with ice and fan, I want introduction to type it in the report, any idea, thanks :smile:

I want to produce a resource that has a narrative and includes the following topics: Sets, logic and proofs, numbers (irrational, integers, rational, …), binomial theorem, geometric series, inequalities, define things like identity, polynomial, symmetry, sigma and product notation. It is in...

Aloha, My name is Charli - I am a computer systems Engineer based in Hawaii working with Lockheed Martin. I end up with a lot of random questions about the projects I do in my spare time and came here to ask some of those questions. My questions are currently based in a small chemistry project...

I am not a physics graduate nor a student. I believe I am an enthusiastic learner. I will need lots of help from you all to reach my goal of decent science literacy.

Hello there. I've recently joined the community of "Physics Forums". My main aim was to learn more about the world of physics from the posts on various questions throughout this forum. I'm currently 16 years old, in High school and have been studying Basic physics for 2 years now. I frequently...

Can someone recommend me a textbook about Introduction to Physics (college level)? I would thank a lot.

Hey there! This is Mayank Bhandare, from India. I am a recent graduate in Mechanical Engineering from the University of Mumbai. Though it's a strange switch as many would say, I am planning to pursue a career as a Theoretical Physicist/Cosmologist. I have a couple of entrances the next month...

Why would anyone like to intoduce a antibiotic gene in a bacteria if it will make it resistant to antibiotics which is not of any advantages to humans?

Hi! I am Bilal Rajab. I have a question regarding Quantum Physics. From where can we learn about Quantum Physics and what is its relation to Classical Physics? Why is there not one single Physics...? Thanks Regards, Bilal Rajab Abbasi

Here's a bit about myself (past stuff, present status, future hopes), though I might not go into enough detail to uniquely identify me: As far back as middle school, I'd say I was committed to studying physics. Although, now I'd say it's hard to commit from a decently-well-informed standpoint...

I find physics extremely interesting, as I'm sure all of you do as well. I'm currently a senior at Oklahoma State majoring in Computer Engineering, with a career path currently slated in Software Engineering. I've purchased several physics textbooks on QM, GR, etc. and plan on reading them...

I am NumFront. I am new on this forum. I'd like to get help for my questions from you respected experts of physics. Thanks.

Hi physics friends, I'm a hospital physicist in Scotland. Though it's a long time since I graduated, I never grow tired of learning and thinking about the wonders of the universe. This looks like a great place, and I can't wait to get to know you all!

Hi, I just registered today and am glad that I did. I am a 16 year old (will be 17 in 4 days) High School student who is into Physics and Mathematics. I've always been into Physics, since I was in elementary school starting in Astronomy then now to Theoretical Physics (Quantum Physics). I've...

First, two examples: 1.The Penrose's book "The road ro reality" may be, arguably, considered as a very fast and dirty introduction to modern physics as well as to some related relatively modern math topics. 2. I recently encountered a book Aleksandrov, Kolmogorov, Lavrentev "Mathematics: its...

Hi, this is my introduction. I'm an italian physicist, ... a Prof. as italian students use to said. I'm an astrophysicist that is working on quantum-relativistic physics unification theories. I love any cultural challenges, especially in physics.

I'm beginning to study the Matt Roots book Introduction to Cosmology and in the section 1.3 Olbers' Paradox he writes: "If the surface area of an average star is A, then its brightness is B=L/A. The sun may be taken to be such an average star, mainly because we know it so well. The number of...

Is there a good introduction textbook or pdf for quantum chromodynamics?
