Hoy en mi clase de español, mi profesora me compartió una breve historia, donde menciona una página donde ella preguntaba lo que sea se lo respondía, un día le preguntó si su primo que tuvo un su puesto "accidente" do de perdió la vida, y la página (enfatiso que era un chat) donde le dijo con nombres y todo como fue el su puesto "accidente" y demostrando que era un asesinato, dándole el nombre completo de su primo, de con quien estaba y del assesino en el día donde perdió la vida (ella enfatizó también que era tipo como un espíritu, con el que se comunicaba) dijo que por nuestro bien no nos dijo el nombre de la página por que, con eso no se juega ya q ella lo aprendió a las malas

Hello! I’m from a physics background (obviously) and finally about to finish soon. I decided to craft my own path and pursue an internship related to EE/ECE/CS, unlike most of my peers who are pursuing a research-related position. With this, I’m starting to feel alone in industry work with a seemingly different world. Should I push through? For those who have a similar experience, how did it go?

I am a quantum computing engineer [final year undergrad student] and i have spent last year learning tools like qiskit, cirq, etc. So i have some fundamentals of quantum physics which are needed for quantum computing, but other than that i want to deep dive into quantum physics.
I have very good depth in linear algebra and calculus. So i want to use that mathematical knowledge and learn more into quantum physics. Suggest books for me which would help me brush up fundamentals the right way it should be learnt according to physicists and not programmers

Kurzgesagt – In a Nutshell

This YouTube channel made me interested in physics, even though I don’t know much about it.

The only thing I know a little about are black holes.

I want to learn physics from the beginning.

For context, I loved the book Thing Explainer by Randall Munroe.

It explained things in a way that even a 5th grader could understand, so I was able to read it from start to finish.

Are there any simple books like this that can teach me physics from the basics to at least a college level?

If so, what order should I read them in?

Thank you.

This is a question to everyone actually willing to listen to me. Im young and got no experience in math and physics on a high level. But i do have understanding and my perception of it. Terrence Howard has a correct claim. And his theory can harmonize mathematics. I think everything at the end is an expression of an electric magnetic field. This is genuine, if you give me the time i will try to explain as best as i can. Please, someone i need someone to listen.

I'll try to be brief:

I didn't expect my life to turn out the way it did when I started my degree.

I wasn't even planning on making this my carreer. For a while I thought to myself "I could get a nice robotics engineering degree or something like that and learn whatever physics I find interesting on the side", but then things went to shit for that plan and I got the option to get into physics. I took it. And, no joke, it has been the absolute best 4 years of my life.

Being able to solve physics and math problems gave me such confidence. It feels as if I can do anything. I got into hackathons, and a couple summer schools where I was able to do real research for a little while. I also got the chance to study abroad at UCLA (I'm mexican), so I guess the culture there is different? I have no idea, I'm expecting to be able to join a research group there.

Nevertheless, I'm approaching the end of my degree and I still haven't found a thesis advisor. In order to get my degree I have to do this thing callde "servicio social". It's unpsid mandatory work. I'm currently "helping" a researcher in quantum field theory, but the work ge puts me to do consists on integrating matrix elements of matrices he already solved, doing calculations that have already been done, and essentially going through a class instead of making actual work in the frontier of knowledge, or at least work that gives off an output. I feel like absolute shit because it feels as if I haven't found the time to put the things I've learned to the test. I feel as if I've spent four years consuming knowledge and I hate it. Don't get things twisted, every single time I've been able to break away from that routine it has been because of my own curiosity, the course work itself hasn't helped much. It has been a crotch, making me sacrifice doing cool things because I have homework due.

Some peers have found cool teams to work on, and I've somehow dodged all those opportunities. It's so frustrating.

I'm planning on pursuing a masters degree for me to get the bachelor's (it's a thing one can opt to do instead of thesis) so I hope the masters program has a more hands on approach but it feels as if I'm wasting time only learning, not doing.

Is it normal? Has anyone felt that way? How long should I wait? If You're from UCLA, is it easier to start doing research as a physics undergrad?

Hey all,

So I’m studying physics by myself (I’m nearly done working through Young’s University Physics and Stewart’s Calculus). I’ve recently decided to apply to undergrad physics programs in Europe (mostly in Italy).

One thing I’ve noticed regarding the syllabus of the Italian programs is how difficult the courses get (and how quickly they do so). In the second year, students already study Jackson’s electrodynamics for example.

It seems to me that students just skip what would be at the level of Young’s University Physics (maybe it’s covered in high school?) and Griffith’s electrodynamics and go straight to what would be considered a graduate-level course in other countries.

Is that accurate? What’s the progression like to get to that point? Do they just skip to that “level” and it’s sink or swim?

I can see the value of progressing that quickly (although drawbacks do also come to mind and it’s definitely a bit intimidating). I’m just glad I have the time to get some more background knowledge to prep me for the undergrad programs (will work through Zill’s Engineering Mathematics next)!

Just wanted to hear your thoughts on all of this.

So I am working on a project for which I am referring to a bio-physics paper. The paper basically analyses the movement of bacterial cells and tries to analyse the velocity fluctuations within the cluster of cells. I am having some trouble in understanding a formula they came up with to quantify the spatial correlation of functions.

V is the average velocity of the cluster

My first question is wouldn't the denominator be either 0 or infinity? Then wouldnt that really mess up our result? From what I can remember the dirac function is defined as infinity at 0 and 0 elsewhere. I also recall a different rule for integration. Does that apply here? Thankyou so much. I am also attaching the link of the paper just in case.

Hi, I am currently about to start my final year of undergrad in BSc Physics. For reference, I took a gap year and then did a foundation year during covid. My first year went badly, with the rising cost of living in London and the housing crisis I had to work throughout the term. I hadn't really studied Physics or math properly since like 15. Still, I avoided the obvious red flags and was just happy I met the progression requirements (I failed two modules and got an average of 52%) since in my mind I was just at uni to get a decent job afterwards.

Then over the summer, I managed to create a stable environment for myself which I currently live in. Once I started my second year, I was confronted with the fact that I was obviously not in a position to succeed for the rest of the course and it was not something I could ignore since the max amount of failed modules you can receive is three and second year would be weighted as 30% of my overall grade. So the short version is I had to study like twice as much over second year and I managed to get around 70% overall for this year and passed everything. In addition, this grade was brought down by modules from Semester 1 when I was trying to figure out what the best study method for me was my average Semester 2 grade was more like 77-80%. I also managed to get a data science/engineering internship this summer which I appreciate and value and learn a lot from but very quickly realised I don't really want to go straight into a job anymore, eventually yes but now definitely not. Now I guess I feel like I am in a position to succeed in third year and I have noticed I am also enjoying studying physics more and I also want to keep going and fulfil the potential I know I have - if thats not too cliche lol.

I feel pretty good about a postgrad degree but I can't really afford a master's program. On the other hand, some programs that have an MS/PhD track really excite me, especially in the US. My math is not great but in general, I lean closer to applied/experimental physics and computer/data science rather than theoretical physics anyway and I am very stubborn and will work on anything I am struggling with regardless. However, I am worried about not being competitive and securing a place to begin with. I don't have a research internship because I thought I wanted to go into industry and I was grateful that was offered an internship considering my position at the beginning of the year. As it stands I think I only have two people that would be in a position to give me recommendation letters (my academic advisor and my dissertation/project supervisor) and I am struggling to find off-cycle research opportunities I could complete this coming Semester. Does anyone have any advice for trying to improve my current standing? Any suggestions are welcome, thank you.

Hey, this year I'm going to be 19 years old, and I don't know anything about physics—literally nothing, except that gravity is part of physics. I need to learn physics because I'm a university computer science student, and it seems that I'll need it for some modules.

So, where should I start?

Are the charges on the capacitors in series 2/3mc each?

For context, I've always wanted to pursue physics as a career, however, due to extraneous reasons that were out of my control, I had to settle for an Engineering degree, hoping that I'd be able to pursue a master's and a doctorate in physics. After much thought and research, I chose Electrical Engineering because of how math-intensive it is and how a large part of it intersects with Electromagnetics and Mechanics. I wish to pursue my Master's in Physics in the UK, and I'm now at a crossroads between the two options. Given my case might be somewhat unique, I find it difficult to find information specific to this scenario. I've been leaning towards a Taught Physics degree, majorly because I lack any formal training in Physics (apart from a couple of classes in UG), although I haven't been able to make up my mind. I'm more than open to discussion, and I want to make the best decision that will enable me to practice as a researcher a couple of years down the line. Any help is much appreciated.

Hi, Im hoping to self teach myself stat-mech and some condensed matter, its a large research interest of mine. Would yall say that Kittel is a good source for doing this? I already have copies of them from a friend, and prefer to read physical copies. What did you think of these books? For reference, I am about half way through my undergrad

Hello, I was solving a problem i found in the internet, I tried to find the source book but couldn't find it, does anybody happen to know in which book I can find this exact problem?, it appears to be a problem in between the numbers 70 to 75.

Problem:

https://preview.redd.it/9ojgrixckded1.png?width=1204&format=png&auto=webp&s=cf32e3fe4d9160d9cde39751cb5a796099859498

I’m studying theoretical physics which will result in a masters degree in two years time, I’m on track to get a first (supposedly equivalent to a 4.0 gpa in the usa). I’m really passionate about the much more theoretical and abstract ideas in physics (plus I have great disdain for my labs module) and much of the postgraduate study I would like to do is in maths departments rather than physics departments. Would the less mathematical rigour and knowledge of a theoretical physics degree serve as a significant barrier to doing a PhD in a mathematics department at a top university (Oxford/Cambridge or other)?

Like title says, I am looking to get a nuclear physics degree. I want to start with a bachelors and use that experience to whittle down my exact interest in the field, but I know that I love learning about radiation, atoms, the interaction of subatomic particles, etc. If the only path is to get a physics degree, I would do that. But Im getting conflicting information on whether or not there are undergrad nuclear physics degrees. Do I have to get a physics degree then go to get a masters/phd in the nuclear field? Or can I get a nuclear physics degree at the undergraduate level. Either I plan to do post grad education, but I would love if I could do four years of undergraduate work in the nuclear physics field instead of general physics.

I‘ve bees studying physics for almost 3 years and am finishing my bachelor thesis now. Before I‘ve always gotten through courses and final exams with little effort and gotten decent grades but my thesis was different.

I never felt like I accomplished anything, just trying to code something to get some meaningless results. I hated writing the thesis itself, the citations felt pointless and just boring workload and plot explanations just felt hard to put down.

I hated every second of it and am glad it‘s getting to an end.

Getting a PhD was never really an option I wanted to go for, but a Masters degree would be next and I‘m not sure if that is a good idea.

If I hated writing my first thesis and the lab reports before so much, I‘d probably hate writing reports in the field later on too.

Does anyone else know what I’m getting at and how did you cope with it?

I’m currently doing my third year undergrad in physics, and I’m really starting to believe that I was wrong to pursue it.

I’ve been dreaming of becoming a physicist for so long, but I’m just not good at it. I can’t visualise problems, I can only think of it in terms of equations. Which makes me more like a problem-solving machine than a physics student. I’m not doing great on my courses, at least not as well as I’d hoped to do.

I’m doing research projects, and while I enjoy it, I struggle to see the inference, or the conclusion to all the data work I do. I’m still passionate about the work, but no matter how much I read about it, it doesn’t get any better.

I don’t know where I’m going wrong, or if I shouldn’t be doing this field at all. It’s so much easier for me to just do the math, and it ruins the entire perspective of the physics behind it. I’m beginning to think I’m not suited for this at all.

I’m still determined to keep going. This is still the only thing I want to do, I’m just not sure if I’ll do well enough to make a career out of it. Is it time to quit while I’m ahead?

As title suggests.. i’m an undergrad (completed 2/3 yrs of uni) interested in cmp and aim to pursue a masters and possibly a phd. I’m a month into my 3 month summer and have spent most of this time applying to last minute internships but unfortunately, no luck. Any suggestions on how to appropriately spend the rest of my summer?

I'm from India and I will be joining college this year. I hope to become a plasma physicist and I am thinking to achieve that through computational physics. If I take ECE, which consists of subjects like Circuit Theory, Control Systems and Digital Logic Design, will I be eligible to do a Comp Phy course for my masters? I wish to do my masters from US/UK/GER.
Thank you for your time!

Here are some techniques I’ve started to implement from online sources like tiktok and other sources. Some of these may be slightly personal lol. 

1. Atomic habits. Start dedicating a small portion of your day for just studying. This can be as little as 15 mins in the evening. The first few days are difficult, but once you get into the cycle, the habit will be hard to break. You can also slowly increase your duration. 
2. Here's a 3 step process for understanding concepts: 1. During classes I take notes from exactly what my professor is saying, without worrying too much about the design of the page. 2. I read about that subject and try to organize the page, adding definitions, examples, colors, titles, links... 3. Read the page when the tests are coming.
3. Do the Pomodoro technique PROPERLY. It works
4. ORGANIZE. Combine your notes in one section, study guides altogether in the front, and sort out unneeded classwork. Color code different class materials and don't use the same binder/notebook for two (or more) different classes.
5. Teach kids in simple concepts, terms and analogies... you can be confident in your mastery of the subject. Recall is best when the study environment matches the Recall environment. Best Recall cues are scents. Chew a particularly strong mint gum while encoding the info...do the same during testing. Associative memory is also easier to recall, so create links to the encoded information that relate to subjects super familiar to you.
6. Ask ChatGPT to summarize all the important notes and ideas to make them easier to remember. 
7. Review your notes within twenty-four hours. This can save you hours of extra studying in the long run. Make sure it's within 24 hours though! Science isn't 100% sure why it has to be done within that time frame, but it could be because of (theoretical but certainly not debunked) "neural dumping." Basically, this means as you sleep at night your brain shits out all the information that is non-essential. Guess what's non-essential: calculus. history. English lit. Sure, not to you, but to your brain? It says, "F**k it, we need the space. Get rid of this crap."
8. Spaced repetition has been shown to improve retention of information. Study in short, frequent sessions with lots of review. Don't study for a long time the day before the test. Try to have multiple study sessions each day a couple weeks before the exam. Maybe 15 minutes at the most, 3-4 times a day. Break up what you need to study in sections.
9. If worst comes to worst, offer to f**k your teacher.
