Awesome, thank you! That confirms my suspicions. I'll have to let the physics freshmen know they can't tell the 10-year-olds it's a hologram any longer. So my question is, how did this misconception arise in the first place? These optical illusion demonstrations are even marketed as...

Hello everyone, An interesting discussion has arisen within my physics department. Would this (https://www.amazon.com/dp/B0002W3J7M/?tag=pfamazon01-20) two-sided reflective dish technically fit the definition of a hologram? We often present this demonstration to schoolchildren, talking...

After speaking with my professor, he clarified that the "6-12" rule is indeed the Lennard-Jones Potential, and recommended that I use that as my central potential. As opposed to Numerov's method, his suggestion was to describe how separation of variables in the time-dependent Schrodinger...

Thanks so much for your response! For the class presentation, my professor stated he was looking for either a 5 page paper (using the blackboard to write equations as needed), or a Powerpoint presentation with an attached appendix detailing code and procedure. I'm not sure, but for this...

Hey everyone, I'm starting a research project for my partial differential equations course, and I've chosen to research numerical solutions to the radial form of Schrodinger's equation. From some preliminary research, I've found information on using Numerov's method, but I am really not...

Ooooooh... Okay, that makes perfect sense! I was making it out to be a lot harder than it was, and wasn't trying to solve it by inspection, but after looking at it with your hints, it's very clear. Thank you both! Just out of curiosity, if the initial conditions weren't given, would it...

Homework Statement I'm not sure if this is actually solvable, or a typo on my homework... but here's the problem in question: Solve the ODE: \frac{d^{2}y}{dt^{2}} + t^{2} \frac{dy}{dt} + y^{2} = 0, y(0)=0, y'(0)=0Attempt at solution I've been stumped on where to even start with this one, but...

Wow, both of those recommendations sound fantastic - thank you!

Speaking as a US college student at a moderately-sized public university, I'm afraid I'm going to have to agree with Cristo here - although I see where you're coming from as well, Lubuntu. As a freshman, I took an orientation course taught by various physics faculty in my department, and...

I like this idea! Classes: Quantum Mechanics - Griffiths, which I think I'll try and supplement with Mendl E & M II - Intro to Electrodynamics, Griffiths again Partial Differential Equations - Applied PDE, Haberman Astrophysics (emphasis on stars) - Intro to Modern Astrophysics, Carroll...

Hello all! So, I'll be taking first-semester quantum mechanics and partial differential equations this fall, and would like to get a little bit of a head start by reading/working some problems on my own this summer. After some initial browsing, I've heard mixed-to-poor reviews concerning...

The on-going armadillo fact file (and its blatant unrelated-ness to the thread) has just made my whole day. I will never be able to look at such a critter the same way again. (p.s., I also heard that their leathery shells effectively repel most projectiles from semi-automatic weaponry. Any...

Well, dang... As of today I was officially rejected from all 6 physics/astronomy REUs I applied to :( Anyone know of any super-late-deadline summer internships?

Congrats on all of those acceptances! That really is quite something. Concerning the choice of going with Fermilab, I don't think that's wrong at all :) A good friend of mine had a great research experience there a few summers back, and another of my classmates will be joining you this...

Dang, so, just got rejected from Hawaii and the Smithsonian (astrophysics)... so this puts my rejection count up to 3/6, with no word yet from the other three. I'm a little more apprehensive now, since I don't know that I have a very good chance of getting into the other ones, and I really need...
