Hello! I joined because I am interested in how physics would intertwine with science based magical systems in books. I'm looking forward to learning a lot of new things and seeing how they would work with each other.

Hello I am a laser engineer interested in Physics.

Recently I’ve been learning more about quantum physics, and Physics Forums has had a lot of good answers to questions I had. I’m looking forward to learning even more, and asking questions that I’ve beenconfused about.

As the title says, I've found out I've achieved a 2:2 (50%-59% average), and am now considering my options. I've read a lot online about this grade and see too many mixed opinions so I thought I could make a post and see what everyone here thinks. Firstly I would like to state that I would...

Hi! I'm a current high school senior and I'm taking two physics classes this year on top of other math/science courses. I'm starting my college applications and wanting to study nuclear engineering. I'm on here to find help with my courses as well as advice for my future!

Concider a planet A, which is a planet just same as earth (for familiarity). When we try to mesure it's total mass (rest + relativistic mass), we have to mesure it from some reference. (Because motion is relative) Let's put reference point as planet B which is moving away from planet A at a...

I am a physics major in the second year and always have loved maths. Now that interest has grown into something bigger and I am thinking of taking some recognized distance courses in mathematics so that I will have something to show in case I decide to do a masters in mathematics. It will be...

I'm not exactly sure what to post here, but I also like robotics?

Hello, I will start with some background, I'm 35, I have 2 bachelor's degrees: one in chemical engineering and the other in genetics/biotechnology. In my country there is no major/minor system, so I studied both careers at the same time in different colleges. You would say I have two majors. It...

This site probably gets similar questions all the time, apologies if its too repetitive. I know the ultimate answer is to keep practicing, anything else is just a way of procrastination (including this post) but I feel like im doing something wrong somewhere. I'll explain this with an example...

So this may be a very simple problem to answer or a very stupid problem to even ask, but it’s something that I thought about and can’t quite figure it out. So my made up scenario is this. Say we have a normal sized man, and when he throws a punch it takes him one second to complete the act of...

I am curious to know if there is any existing topic explaining how objects break into several pieces when force is applied.

I have been looking for days for a physics community through social sites but they only have good memes. Hoping to learn and share meaningful things with this community.

I have a BA in math. Took no physics courses. In the few years since I graduated I've self studied a lot of physics in my spare time and have a desire to pursue a formal education in it. I understand it would be almost impossible for me to get into a masters in physics unless I went back and...

Hello everyone, I am very new to physics, I'll leave that at that for now. However I came here because I am in the process of coming up with a build for my own generator and honestly I loved electrical engineering just didn't have the ability to pursue it. Now I have been brainstorming and am...

Hi. I am new here as a participant, but I have been reading and studying from some answers in this forums (and many others of course) for different degree courses related to physics etc. Right now I am in a PhD in control systems and I am learning about systems modeling and control, and that is...

Does anyone know where I can find all the ionization energies of Germanium? hbcp.chemnetbase.com shows only the first 5 and winter.group.shef.ac.uk only the first 21. I need them because I would like to reproduce a plot of the ionization of Germanium in a plasma. Since this plot exists I assume...

I found Physics Forums via Google search. I'm a Tanzanian citizen pursuing a bachelor's degree in Physics (minor in Economics) at The Open University of Tanzania. I'm a first year undergrad. I'm glad to be a part of a huge community of like-minded people. I'm especially passionate about...

May be It's a concept problem.

Hey, some questions are bugging me about career choices available. First my background> Masters in physics from non programming type degree(remove c and matlab). So as you can see from above i have to do masters again for job prospects in america ,germany,uk,canada etc. Now questions are:what...

Hi! I am happy to join this great community. I'm Haia, 24 y/o and own Masters degree in Physics. I would love to have friendly and proffesional conversations! :)

Hello my fellow physics enthusiasts!

Hi everyone! I've begun teaching myself physics with the Feynman Lectures books. However, I find the exercises so difficult. After reading a chapter, I struggle with how to approach the exercises effectively. I understand that this isn't an easy process, but I feel I need a deeper understanding...

I want to be a member of this forum for the prime reason to learn about other aspects of physics that currently I am unaware of.

Hi, I am a physics graduate but now I am teaching middle school science, I have been struggling because it seems that everyone is looking at me as a teacher rather than a physicist and the fact that I lost a lot of my ability to do physics only makes things worse. was anyone in a similar...

I hope this is the right forum right now I’m a 2nd year physics student in the United States and I’m really interested in nuclear/plasma physics. The thing is that I know the U.S. has great national labs to do internships at and good graduate schools here but I’m also interested in studying...

I understand that there are vacuum solutions of the equations of general relativity (GR) (i.e. equations with no mass-energy content contributing to the stress-energy tensor), that are studied by physicists interested in GR. I don't understand why these are studied or what purpose they serve...

For the past few months, I've been on a look out for the best physics community on the Internet and I've just come across this one. My primary goal is to gain as much knowledge as possible in the area of classical mechanics and electromagnetism in a year. I'm fairly new to magnetism, but I can't...

I am a second-year combined honour in physics and math with prerequisites for 4th-year math courses. I am hoping for a direct entry (if possible) into a top US PhD physics program in quantum with a current unofficial cGPA of 3.9/4 (88%). Since I am in Canada, we only have percentage grades that...

Hey guys, I am Henricus. You can call me Henry. This year (accurately 2024) I'm a middle schooler and i have an interest to physics, especially quantum physics & particle physics. If I had a chance, i would like to get a scholarship in theoretical physics. I've learnt Lagrangian and Hamiltonian...

I was born 1963 and received my bachelor degree in Physics which I found it very attractive subject.

Hello! My name is Graeme and I'm pursuing a BS in Astrophysics. I have undergraduate degrees in business, economics, and analytics, and a Masters in business analytics. When I was nearing the completion of my MS, I rediscovered my love for science and enrolled in this BS program shortly after...

Hello, everyone. Thank you for allowing me to post on your forum. I am not good enough at math to become a physicist, but I love physics and found this forum through my Google searches. Hopefully, I can learn enough here just to call myself Smith

I’m a physics major (going to be a junior in the august) that would like to go into astrophysics!! I picked physics for a major bc i like knowing how things in our world work + i’m especially interested in space. I lowkey am just seeing where the wind blows me so I really don’t even have a fully...

If someone believes they have developed a somewhat unified theory that brings together various physics concepts into a Unified Theory of Energy, but they are concerned about being dismissed or criticized by members who strongly adhere to conventional academic views, where in the Physics Forum...

I have been using Maple for a decade, but only recently started using the Physics Package. I unfortunately ran into trouble to contract indices ( Maple calls it SumOverRepeatedIndices ). Below I give an example that will execute if you paste it into a Maple worksheet. A metric is defined. A...

Hi - AP Physics teacher here, from Florida. Happy to join in!

Hi. I need your help! I have a college physics question Suppose there are pipes A and B. [Figure 1] I had to connect pipe B to pipe A, but pipe B was short, so I bent A by about 30 degrees and installed it. [Figure 2] It's a picture of the pipe A being installed by increasing the length in...

Good day to all. I'm a new member who is fascinated by and interested in physics, quantum mechanics, astronomy, and cosmology, though I never took classes during my schooling. Admittedly, I have basic math skills and worked hard to attain mediocrity in math classes (a living example of the law...

Student of master of physics.

Hello, can anyone tell me about applications of Diophantine linear equations to physics?The only example that comes to mind is that of a series of weights. I have a measuring rod that is 40cm long and hinged in the middle. If I put a 40g weight at one end, how can I place 5g, 7g, 11g, 13g, 17g...

I have had a life long interest and fascination with physics and love to learn more about the different aspects of it. This forum is greatly appreciated for the wealth of knowledge and experience that is freely shared amongst the members. I apologize in advance for my child like wonder and...

Hello everyone! My name is Amman, and I'm thrilled to join this vibrant community. I wanted to take a moment to introduce myself and share a bit about my background, interests, and what I hope to gain from being here. Background I hail from a small village in Pakistan, a place that holds a...

Hello Everyone. Thanks for accepting me as a member :smile: . The bar for joining was set exceptionally high, yet here I am! I am a phys grad, and read physics books when I have the time.

For anyone interested in ‘what it used to be like’… Sifting through some old paperwork, I found one of my 1967 A-level physics exam’ papers. For those unfamiliar with UK ‘A-levels’ in 1967, they were national examinations generally taken in school at about age 18. Students typically studied 3...
