Hi all, I am a math undergraduate who studies math solely when I crave dopamine — when I feel a “kiddish,” soaring excitement. As a result, however, I am unable to focus for consistent, long periods of time and thus succeed at research. For this reason, would any of you happen to know if any...

I am currently in the beginning of my Junior year as a physics major. This semester I am taking Electromagnetic Theory A, Mathematical Physics A, Mathematical Physics B and a special topics course (which consists of some minicourses and seminars on a range of topics in theoretical and...

I live in the SF Bay Area. I graduated in 2019 with a B.S. in Engineering Physics from UC Berkeley. My college experience began with me failing to actually sign up for orientation, and then contracting tonsillitis which lasted my entire first semester. The combination of these two things...

Hi, I am a master's student from India (with a CGPA of 9.75/10.0, equivalent to 3.9/4.0) who will be graduating in July, and so I am looking for PhD positions (in Europe). I am torn between selecting hep-th and selecting hep-lat for my PhD research. I have hands on research experience in...

Hi. I have just written a draft of my personal statement. I am still working on it, but there are some concerns that I am not sure about. 1. Is my opening too tacky? 2. Do I talk too much about research experience? Maybe I should cut some details out. 3. On the contrary, I feel that I do not...

So I need some advice of someone professional and experienced. I’m 16 just about to sit my GCSEs soon and I’ve got a plan of what I want to do in the future. I reckon for my age I know quite a lot about high end things in Physics to do with quantum physics, special relativity, string theory...

I started my PhD in physics at a position associated with a project. In the project I'm the only one working in my field and the only one working full-time that knows how to program (a computer scientist is also working on the project but only 50% and has another supervisor in his field). I...

I have a major in mathematical physics and mathematics and I've started on graduate school january of the last year to get a master's degree in theoretical physics. My real interest is fundamental physics, specialy related to general relativity and quantum field theory. I've talked to a...

Grad school is *not* what I was hoping it would be. I wanted to study GR and was fortunate enough to get accepted in a program with an advisor who is a gravity theorist. I have the best fellowship awarded to grad students at my school. I passed all my prelims on my first try. My grades...

Hi, My name is Rodrigo and I need to achieve a permanent seal for a vacuum chamber in the high vacuum range (I’ll be working between 1x10-4 and 1x10-torr). We were thinking of using a cold-weld sealing of an annealed copper tube to separate the chamber from the vacuum pump once the vacuum level...

Hello! I'm a junior in high school, and my school requires that every senior complete a "senior project" along with a research paper related to your project. Pretty much, you're supposed to do something that provides you with a learning experience or something that can help you grow as a person...

Hi all, first-time poster here excited to get my first telescope working. The issue: I see the silhouette of the secondary mirror and spider vanes in front of everything I focus on! I read through a similar post here a few years back, but the solution didn't work for me. Details: 6"...

Due to extenuating circumstances that I am not going into at this point (however, I may provide additional details if necessary), I am considering I have a MS, which I earned prior to dropping out from my PhD. My MS project was on a theoretical project involving topological defects. Thus far, I...

I have three semesters left before I get my BSME. I went back to school a few years after high school, and a few years later (I had to start at the very bottom, seeing as I didn't even pass algebra in high school) I got accepted into an engineering school. I've done well enough up until now to...

Hello, I'm in a situation where I may have to leave my PhD program (math). Let's not go into the details because I'm not sure how anonymous I am on here. I'm just trying to figure out what my options are at the moment. I have an undergrad in applied math and an MS in physics (not ABET). I'm...

Hi. Currently a junior in high school. I love math, and am currently either deciding between going into math or engineering. Because of this, I'd like to take as much math as possible and really challenge myself before I go to college. I'm currently taking pre-calculus at my school, but next...

I am currently in my second year of a bachelor of science with a major in physics. The class I am taking is notorious for being hard and the professor is very hard to understand (understanding the material, not what she's saying). The class is all about oscillations and waves. The textbook is...

So I really have a few questions. First, is it wise to take the following classes in the same semester? Quantum Mechanics I - At the level of Griffiths' Intro to Quantum Mechanics, chapters 1-5ish Classical Dynamics - At the level of Thorton and Marion, Chapters 1-12, ends with coupled...

Hi all, quick question about a PLA circuit I'm doing for coursework. I'll upload a pic of the circuit to help explain. I've got the main stuff worked out but a little line in the coursework is making me think if I need to add a couple of extra connections on it. The circuit has 7 incrementing...
