Hi, new to the forum and checking in ✔️

As I was asked to say hello, here I am. I am not a scientist, did work in finance, suspect it is like a dog chasing its tail and that the next century is the right one to be a life scientist and the next thousand years is the right time frame to be a physicist.

Hello guys, I'm new here. Hope to gain knowledge and help others along the way. Thanks

Hello everyone, let me introduce myself, I'm new here. I have a few questions about semiconductor devices and was looking for a physics forum and found this site. I hope to find answers to my questions and help others if I can. I hope to find answers to my questions and help others if I can.

I am a public high school math teacher who connects relevant physics facts to the maths students are studying. I hope PF will provide grist for my mill.

Yes

I'll be starting Apostol's calculus book in a little less than two weeks, as I'm finishing up an easier textbook. I looked ahead and I see that there is a four part introduction, and I was wondering if I could just skip that. I briefly skimmed it, and it just looks like a review of summation...

Started a Physics Degree at QMC in London 1 in 1978 but swapped to an English Degree in Canterbury in 1979. Mostly an accountant these days but been a mini video-producer, hairdresser, worked at BT. I have my Raspberry Pi but not yet into programming. What *IS* a computer? A logic machine? And...

Hi all. Started a conversation with Chat GPT about the big bang, C, gravity, time, thought experiments and other things that I mull over in my brain every few months and it suggested I talk to someone that's actually studied some of the things I asked about especially as things change...

Salaam alaikum, I'm Sanaa. I have joined this forum to enjoy my experience learning online completely.

Hello everyone , ich bin eine neue Studentin, freut mich hier mit euch zu sein

How did you find PF?: Science article link about the Universe being twice as old by an Ottawa physicist. Hi people, I am unsure about what the requirements are for posting to this forum, but upon posting a basic comment on an article I was given an almost unimaginable list of requirements and...

My name is Les and in 1977 I began studying Physics at Texas A&M university, After four years, I decided a career in Physics was not for me. Since then Ihave been working as an Engineer.

Hi Physics Forum. Greetings from Denmark. Best Daniel Twellmann

Hi, My name is Albert, and I'm here to learn and share knowledge and experiences throughout my journey in physics and human sciences.

I'm supposed to enter a valid message so here we go. I'm a girl obv and very much interested in physics. Found this platform on google and thought it might help me quench my thirst of ever growing curiosities. Yea, that's it pretty much

looking for answers to a problem I had while building my final year project prototypes that uses a 12v dc motor on a Google link that brought me to this forum

Came across this forum wanted to state first I have no background in physics but have been reading through a lot of these articles and would like to learn more. I just posted a thread on a question I had about materials that passthrough IR. Looking forward to seeing more posts with individuals...

I want to become an astrophysicist and hope to learn a lot about physics from this forum.

I'm a teenager eager to learn more about math and physics. As a self-directed learner, I'm particularly interested in calculus and linear algebra. I'm thrilled to be part of this community and look forward to gaining knowledge and engaging in enriching discussions. Your expertise and insights...

Hello, I don't have much to say at the moment, I just signed up on a recommendation from HN and thought I'd give it a try. I'm probably mostly here to lurk and read older stuff, but I figured it was worth making an account and introducing myself.

Hello everyone. My name is Przemek. I am from Poland and I am intrested in quantum physics and intermolecular forces.

Hi, hope all are happy souls! cheers!

Hi there, good to meet you all, looking forward to our discussions!

Hi PF! I am a new member and looking forward to learning new things here. Thanks!

Hello! I am Logan, I am a student and i like chemistry! I came here because I was searching for an answer for a reaction I did but found nothing elsewhere.

I'm out here

Hello!

Hello everyone!

Hi, new member here. I'm a fiction writer and could use a bit of help in writing scenes based on real science. It's harder to make something up that clearly defies the laws of physics. Looking forward to dive into the forums. I'll try not to pester you with stupid questions, but please forgive...

Hello everyone! My name is Psyklon and I work as a full-stack developer at my job. In my free time, I mostly generate things on my computer like fractals, cellular automata, and various other generative arts. Since I first read about fractals I was fasciated by them, so I started to dive...

TL;DR Summary: education, history I need to devise a module for next academic year which is an introduction to pure mathematics. They need to use this module as a stepping stone module such as number theory, group theory, combinatorics, real analysis. What should I cover to make this an...

The code with no modifications is at the very bottom. For part 1: loading a mat file into the code, I just put it above the last function but it's going to have to replace the data part of the original code thus I have to extract it out of the file: (I would add the file but I am unsure of how...

Hi! As a kid, I remember wanting to become an astronaut. "Honey, you need to know lots of math for that!", replied my mother. She knew how much of an enthusiastic student I was, especially regarding the things of the world. That was one of the first graves to be dug in my own, VIP "Cemetery of...

TL;DR Summary: Looking for literature on O(N) vector model Hello, We have been going over the O(N) vector model in my QFT class but the notes are not very detailed and we are not using a textbook. Does anyone know of a good QFT book which goes over this material? I have a copy of Shrednicki...

I came across HSB for the first time when I was reading a guide on Java. What is the difference between the two, and how do you convert from RGB to HSB (and vice versa)?

What combination of resources can you recommend for introducing people to spherical harmonics? Assume that the audience has the mathematical maturity of first-year grad students in mathematics, and will want a decent introduction to the theory and constructions. But also assume that this is part...

Which textbook is recommended for a modern introduction to QFT? What mathematical topics do I need to know to start studying QFT? From which textbooks can I learn them? I know calculus, linear algebra, mathematical methods of physics (the necessary topics for quantum mechanics). I learned basic...

Hi, As an Undergraduate student I'm looking for some textbooks and/or articles as an introduction to superconductors. I have a homework to do as final project not exactly in this field but related. and I would like to understand what exactly is a superconductor as well as use those textbooks...

Nice to meet you all! I am a college dropout self-studying math. Before dropping out, I flunked out my Calculus class even though I managed to pass my Precalculus class (I honestly don't know how). I realized that I was lacking a lot in Geometry and Trigonometry. My understanding of algebra is...

Hello everyone! I'm new to this forum, and I've tried looking at all the conventions on the forum, but if anything I say is out of line, please speak up! With that out of the way, I've added some of my background in physics in the spoiler, with the main questions below that. Looking back at...

How did you find PF?: I searched google for a Physics Forum I searches Google for a Physics Forum, to enable me to pose a question to people who know more about physics than I do. I have no detailed physics knowledge, but do read a lot of science articles, so understand most of the basics. A...
