I always thought it was odd that we know dark energy expands our universe, and that we know it has been increasing over time, yet no one ever expressed a "true" size of the universe (not "observable" universe, the ENTIRE universe) by just reversing the process of expansion based on our...

I had been thinking the area I wanted to specialize in was theoretical astroparticle physics. After digging deeper into the exact roles of various sub-fields, I realized what I actually want to do lies in theoretical cosmology. Essentially, I want to study dark energy, or dark matter as a...

All the partials from the del function cancel, just breaks down to ## x \hat{x} + y \hat{y} + z \hat{z} ## The del function only operates on vectors to the right of it. So, with the first ##\vec{r}##, when you do the parenthesis, it just comes out to: ## x ( \partial / \partial x ) + y (...

Apologies, I used "*" instead of ##\cdot##. The exact problem was: "Calculate ##(\vec{r} \cdot \Delta) \vec{r} ## in cartesian coordinates" With my final answer, I kept the partials (taking into consideration the possibility of a vector like I mentioned previously), so I wrote it out like...

While I only have a minute to touch on this right now, when I solved this, according to my instructor, I did everything right except at the very end, I didn't drop the partial vectors for each direction. The reason I didn't do so is because up to this point, my understanding was that a vector...

Something like that could be very easily addressed on these forums by having someone have some sort of tag attached to their user ID on here (to indicate their current education level). What you touched on though is a much smaller part of (what I feel is) the bigger issue A solution to a...

No need to apologize at all. Like I said, that was just a general blanket statement. Not specifically directed at you by any means. And what you are saying there, that's pretty much exactly what I use the resources like AI for - if I realize I'm spending an unreasonable amount of time stuck...

Ok, I'm going to be respectfully completely open and honest here. This website (and those that most frequently assist on it) are WAY WAY too overboard with the whole "you have to do all the work," "don't let anything else do the work for you" "don't check your answers" "show us every single...

This right here. The equations themselves were pretty clear-cut imo, and so I knew I had all those right. But with Python, I didn't even know where to start. I wasted about an hour trying to compile it and getting errors before I asked for help. While ChatGPT got the equations correct, it...

Thanks. Like I said, I do use it for more as well, as I always like to check my answers after I complete problems. I don't know many students (I'm a non-traditional older student that just came back last semester, so I have hardly any connections other than a few class group chats that people...

I use ChatGPT at this point as basically my personal tutor. It has been a huge help in learning Python code, fixing issues when I'd have them, verify it's working as intended, etc. Also helped me with some of my problems in other classes too (it's difficult for me to make it to office hours a...

Thank you, and that is one thing I considered. As I stated in my previous post though, it is VERY difficult to find a job in this area these days. I am highly qualified for multiple positions, but after a company I was working for shut down, I was unemployed for nearly 3mos early 2024. And I...

I'm fine getting rid of some of my stuff, but I have kids (and yes, already talked to mom and worked out how we would make it work if I left the state). There are some things I have for the kids or from the kids that I will absolutely not leave behind. And I have enough other necessities or...

Are you saying that some grad schools will let you do a physics grad program without even having to be there most the time??? That doesn't sound right to me at all. Every single one of my physics courses expect us to be there physically every single day, physically show up to recitations, etc...

Well, choosing the school that offers the best program for me is why I don't know where I'm going to end up. That's exactly what I'm looking to do. Maybe I explained it in a way that came off differently. As far as once I get there, I can find a place online to move into once I get there...
