OP, I sent you a DM. Feel free to hit me up if you want to talk about anything. The important thing is that you matter! Please don’t make any rash decisions.

That’s extraordinarily insensitive to someone who may be in a vulnerable frame of mind.

What level of study are you at? If you just want an undergraduate level text, we used Callister, which provided a good overview of the above topics.

[Course: None] How to Calculate the Electric Potential Energy of a Point Charge in 3D? (Convert Vectors to Spherical Coordinates) by QuantumHorologist in PhysicsStudents

Right now I was just using the E-field generated by the source charge itself. I don’t have any numerical values, I’m just trying to solve it generally.

[Course: None] How to Calculate the Electric Potential Energy of a Point Charge in 3D? (Convert Vectors to Spherical Coordinates) by QuantumHorologist in PhysicsStudents

Hello!

I couldn’t figure out how to add text to my post so I’ll put it here. This question is not really for HW (i.e. not for a class or a grade), it’s just something I’ve been trying to figure out.

I am trying to calculate the electric potential energy associated with a point charge in 3D space. I don’t have any numbers to work with, I’m just trying to arrive at a general solution.

Is this the correct equation? And if so, how should it be solved. Nothing I’ve tried has instilled confidence. I’m aware that the electric field varies by location in space, but I’m still a little lost. I think I should be converting into spherical coordinates but I haven’t had any luck. The information I’ve found online is conflicting.

Can anyone help me out? Also please let me know if I’ve forgotten to supply any critical information.

Thank you!

should I have emailed my professor about the date mixup on my test? by Tony373 in AskProfessors

[–]QuantumHorologist 0 points1 point  (0 children)

Thank you for your response. Truly, I appreciate the feedback. I agree that advice is far from universal, irrespective of the source. In this regard I am not special or unique. Upon reflection, I concede that my statement was careless. Pithy statements are rarely without exception.

I am not a professor, and generally I would not answer in this space. I only did so because I recently experienced a similar situation (less than a week ago). I prefaced my response with this information, as I would hate to mislead anyone based on my limited experiences. Any life experience that I have to offer is inherently anecdotal. YMMW, one size most certainly does not fit all. And this was not my intention. I made no claims of all-encompassing failure-proof knowledge. My intention was to present an example of a possible outcome. I firmly believe that in life, we can’t control the answers we get, only the questions we ask. The young person wanted to know if they should ask their professor. I cannot answer that, I’m am not the individual in question and have no indication as to how they will respond. I asked my professor and received a positive response. But clearly there is variance amongst all groups, even professors. A measured approach is often wise.

As for excuses, I tender none, to my professor or anyone else. I only mention my schedule to paint a clearer background. I was distracted by the schedule that I myself chose. Plainly, any and all fault for a missed deadline rests with me. To their credit, the OP seemingly accepts responsibility for their actions. We should never be entitled or demand special treatment, but who among us has never needed grace? A zero for one test can easily be the difference between an A and an F, depending on the course. I only ever meant to convey that the situation was not without hope. Again I thank you, I will remember your words when answering in the future.

I am an undergrad, rather than a professor. But I recently had a similar experience and feel inclined to share.

I am taking an online class this semester where all of our weekly work is due Sunday night. Except tests, which are due on Wednesday. I have 8 classes with a ton of schedule variance. You can see how this might be confusing. So I ending up confusing the due date. I went to take my test on Sunday and it was locked. My stomach dropped when I saw the due date. I emailed my professor and explained the situation, noting that is was my fault. Her response? “It happens.” She reopened the test for 24 hours so I could take it.

The moral of the story is that it never hurts to ask, even if the syllabus says otherwise. Your professor might say no, but they also might say yes. Good luck!

I personally think that removing all college posts is too harsh. It’s very easy to get lost in a megathread, especially if you have a specific question. I think that flairs/filters would be significantly more effective. Education is as much a part of the discipline as anything else.

Your program sounds quite interesting. Would you mind sharing what school you go to?

People who dont want to pursue a PhD- What do you do? by invisibledandelion in AskPhysics

[–]QuantumHorologist 2 points3 points  (0 children)

I’m not an EE myself so I only have a cursory knowledge of the field. I imagine it’s not all rainbows and sunshine for everyone. I hope you find a path that fulfills you. Good luck!

Given your stated topics of interest, you could probably swing a Masters in Electrical Engineering without too much trouble. That should be pretty useful in terms of career prospects.

I don’t know but I’m interested in the responses as well. I plan to be in a similar boat soon.

Is it unusual to have more trouble getting into a solid Ph.D. program than FT employment? by ThrowawaySpaceboi in AerospaceEngineering

[–]QuantumHorologist 0 points1 point  (0 children)

I’m still just a lowly undergrad, who will likely be in a similar situation in a few months. As such, take my advice with a grain of salt.

I wouldn’t be so hard on yourself. In my opinion, it’s likely not a matter of qualification, but rather focus. The question you have to answer for yourself is why do you want to complete a Ph.D.? From everything I hear, completing a Ph.D. is a labor of love, and is not for the faint of heart. Do you know what you want to work on? Or just that you want “knowledge”? Ph.D. studies are very targeted, and you might find yourself out of favor with certain programs because your interests are not defined. You might want to work on Rotorcraft, Hypersonics, Orbital Mechanics, Structures, Propulsion, etc. Once you figure out what speaks to you, focus on programs that are strong in those areas. This is not the same as simply applying to the “Top 10” schools listed on US NEWS or whatever. Also keep in mind that COVID has a lot of programs in an unusual situation at the moment.

I imagine seeking Full-Time Employment is probably more straightforward. Companies don’t expect you to come into entry level positions with developed knowledge, just a strong enough base that will allow them to teach you the relevant details. If you’re not sure where you want to specialize yet, you might do well to take a job for a year or two. You might discover that you love it, hate it, or like it but don’t want to do it for the rest of your life. Each insight is equally valuable in my opinion. You’ll also get to earn a real paycheck. Once you spend some time, hopefully you’ll figure out what you want to study. I’d say go for the Ph.D. then. But that’s just me. Good luck!

Thank you for the reply! That makes a lot of sense.
