Please be nice! I am new to forums in general XD

Hi, i am a physics graduate from greece and i am trying to think of ways to laverage my knowledge amd skills online. I am specifically trying to find a way to upload mini courses online for people to buy and make some income this way. Do you have any advice on how i should start and do you have...

Hi everyone I'm a mild physics enthusiast but I wonder if people thought time travel was technically possible? And if Nalini's thoughts were sound on a scientific basis.

HI all! New here, have tons of questions about physics :)

I am a retired programmer 1980 to 2012, renovating old houses in Goderich Ontario Canada, which is 40 kilometers south of the Bruce Nuclear Facility, 6,600 megawatts on Lake Huron, also in the midst of hundreds if not thousands of wind turbines. I am a climate change believer and wish to...

Hi everyone. I've had an avid interest in several fields of physics all my adult life, now 79. (Long retired as a psychologist.) My fields of interest include cosmology, astrophysics, relativity theory, quantum physics and philosophy of science applied to physics. I look forward to participation...

I'm not quite sure how to apply conservation of string to this problem, so guidance would be appreciated. Normally as long as there isn't a "sub-pulley" I can do the problem fairly easily but this one tricks me up. Thanks

I'm just google about my curious questions about physics, and then I got here. I'm keen on doing physics problems and other related fields. Hope this place will give me a memorable experience.

I am a senior living in New York state getting ready to submit my college applications. Colleges I Have Looked At: RPI, UoR, RIT, Clarkson, WPI, Stony Brook, and Binghamton My stats: 3/309 in my class 99% unweighted gpa 1440 SAT (790 Math, 650 Reading) (This score is likely to improve (I...

Physics is amazing and excited to be in a community of seekers.

Hello, everyone! I hope you have a great day. I'm from Colombia, and I'm currently in my last year of a Bachelor of Science in Physics with an AGPA of 4.3/5 (Colombian Scale) and 3.6/4.0 (converted using Scholaro). I'm from a top university in Colombia, but we're ranked in the top 2000 on the...

I have gone through this platform and I believe this platform will enhance my learning about physics

I'm Malaysian, and I'm definitely going to study physics. The thing that I'm worried about is that I do now know if I should do my bachelor's in Malaysia then go overseas, or should I just go overseas? I've asked my relatives about it, and they say that my bachelor's is very important and...

I am at a crossroads in my life. After graduating high school, I went into the ministry. I had no plans to continue my education, and I was content with my perfect little Christian-centered world. Eventually, my faith was shattered and I came to the realization that my entire worldview for the...

Hello everyone, just serving up a quick introduction. I took some physics and math classes during, I believe, the Eisenhower administration (anything before 2000 is hazy). Nevertheless, due to a lack of scientific acumen, I will be a taker, not a giver, on these forums. Here's to a second...

…but then I dumbed down in later life :sorry: Here’s to hoping this visit would change that :woot:

What's the difference in content between the two textbooks? International Adaptation and local edition Principles of Physics: Extended, 12th Edition Principles of Physics: Extended, International Adaptation, 12th Edition

Can I post Operations research problems in Physics Forum? If yes, where, can I post it?

Hello to everyone. I'm an undergraduate physics student and a private teacher.

Came to know about physicsforum by mistake . One of the best ones I made. I was suffering in undergrad. Will hopefully suffer less now onwards.

Hi, I start my PhD education, actually offically it was one and a half month. And ı didn't decide to choose to experiment or theoric. Maybe, if you know or study this field,help me to decide. What is this two field advantages in STEM? If ı choose theoric, ı can find a job? Thanks for your answer...

Hi everyone! I finally decided to go down the path of getting my engineering degree. I never had physics at school so I have to do a uni ready program and catch up on most of the course in my own time. Ive been quietly reading here for a while and it's actually been very interesting to start...

I'm a physics and engineering enthusiast! I really love the format of this forum

hi, i love watching videos about physics and mathematics, but i have no practical knowledge, i could not make the calculations or predictions for anything ;)

Hi I am a Physics Graduate and I have qualifiers coming up. Looking forward to sharing valuable info and to learn from this platform.

PF should keep up with the times https://www.livescience.com/planet-earth/nuclear-energy/physicists-solve-nuclear-fusion-mystery-with-mayonnaise :wink:

Hi Friends and Colleagues! It so happened I give classes of electronics in certain local school (which itself is physics-oriented) - as a hobby, once a week, perhaps more than 15 years already. Meanwhile by occupation I'm a meek programmer and years ago I created some programming-puzzles...

Suppose that Bob and Alice decides to do a quantum experiment, more precisely, The Shroedinger Cat Experiment. Alice goes to the Andromeda Galaxy, and wait for Bob’s results. According with the MWI, the wave function never collapses, suppose that in one world Bob found the cat alive, in the...

Hi, I am 10th grade student from Lithuania and I am really interested in physics. Studying further course on my own, but the problem is that I do not have a teacher or helper to ask questions. Hoping to find help here!

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...
