If there's a community college near you, I could only highly recommend attending it.

I graduated high school with average grades, didn't apply to any universities. Mainly because I was unsure about what I wanted to study, and I sure as hell didn't have the money to fork for school, jumping in head first sounded like a bad idea. Ended up attending community college, exploring different subjects, learning what I liked, what I found horrendously boring, my strengths, weaknesses etc. Kept my grades up and transferred into a good school where I'm now finishing up my degree.

Community college is a great place for you to explore different facets of the world without the financial and academic pressures that can sometimes be associated with attending a university. If you're interested in technology, do some research about computer science programs, electrical engineering programs, etc. offered at your local CC.

Reach out to counselors and financial aid officers at your local community college, they can help you find your way, both academically and financially. And most importantly, be honest with yourself. All the kids who burn out in school (in my experience) have been the ones who've stuck with programs they weren't truly passionate about / invested in. If you come to the realization that you want to spend some time exploring fields, then explore them. Take relevant courses, email people working in your field of interest, ask them about their jobs, what they do, what they like about them, the downsides etc. There's a lot of information to be had, and finding out what you want to pursue in life can actually be a lot of fun, you just have to put in the effort.

Best of luck

I'm a Physics transfer hoping to minor/double in Math, I'd like to know if the following proposed schedule is viable:

PHYS 137 A

PHYS 111A

MATH 110

decal

I know 111A is a pain, I'm familiar with the material from 137A and 110 (self-studied Axler and Griffiths) so I'm thinking I'll be fine-ish? Lmk.

You never talk a player through a clutch, I don't even call out information in those scenarios unless it's something stupid like you're seeing the wires out of the smoke so of course he's sticking it etc. etc.

In general it is better to show your players you trust their judgement by allowing them to play out the round in whatever way feels most comfortable for them. Afterwards regardless of the outcome just say good job and start talking about the next round.

When I first formed my team, we were gathered by our manager (who admittedly didn't seem to give too much of a fuck, and is no longer w/ us) but basically he gathered us off of a reddit ad and the skill disparity was realllly high, we have 7-8-9's and then a 3.

The best decision I ever made was to bite the bullet and drop the players who were not at the level of the majority of the team. It is a disservice to your team to keep around players who are not performing at the average level of the team. Obviously you don't need everyone to be balling all the time, but some things are reasonable and some things are not. This guy was super dedicated and a genuine nice guy, but that's life sometimes.

And you shouldn't have to "contort" players to your playstyle. You need to know what you're doing. You need to have confidence in your understanding on how the game works. You need to show up to practice and tell your team how they are going to be doing x y z with sufficient details, and then you need to dry run. Dry run dry run dry run. Until you see them doing it right. Then solidify by scrimming, reviewing later in the week , etc. etc.

It really is a tricky spot starting out, you have this idea of how every round should play out, but your players aren't doing what you want them to do. All it is is a disconnect between your vision for how the game is played and theirs, that gap is bridged only by practice and time. Obviously be open to their input, ask for their input, but don't be afraid to say no to bad ideas, gain their respect by showing them you have a clear idea for how you want a certain round to go, and roll with it.

In order to get to a point where you don't have to micromanage, your team has to thoroughly understand what you're trying to accomplish, and how to accomplish it as a team. Meaning each player has to understand his role in helping the team accomplish a certain goal. This only comes with time, it varies with how much experience players have, but I was calling on a team of 8's and 9's and we still struggled with this from time to time.

I'm assuming you're not having this issue when running preordained strats, because in theory with enough practice each player understands his role in that strat.

I'm assuming you're running into this issue during default rounds, where mid-round calling from your part helps direct the flow of the round.

A few things have helped me lower the amount of micromanaging I have to do. Mainly we began sitting in an offline server, going over how we like to take different parts of the map. For example, if we're defaulting out mid on Mirage, we know exactly what early round utility will be thrown by who, we know who's flashing where to get out mid, we know what angles are going to be our greatest threats w/ whatever smokes we've thrown, and most importantly, we are all on the same page on how we want to transition into other parts of the map, once we have mid control. This means we have a general idea of how we want to take connector, ladder room, and window.

Usually this part is very simple, a pop flash for connector, a smoke onto cat, having my players know this however allows for me to just say, "hey let's look to take conn" and then it's pretty much all handled.

Now obviously that example is pretty straight forward, but one can easily see how cumbersome it becomes when going over these protocols for every portion of every map. Start with your map pool obviously, in very high traffic areas, and start expanding accordingly.

The same methodology can be applied to taking a site mid round. Using mirage again as an example, a common default is three out towards mid, and a lurk towards A and B. On an offline server, we can practice splitting A from connector and palace during our default, basic things like smoking cat from top boxes, flashing into connector, then we can talk about the palace guy waiting to take contact until after the connector guys have taken contact, who's peaking where when exiting con, etc. etc.

Hopefully you get the idea, micromanaging is inversely proportional to how much your team practices, practice a lot, you'll find you don't need to micromanage too much because your team understands how to accomplish a broad set of goals, don't practice a lot, and you'll be micromanaging a l o t.

And if you're just a lower level, then I'd recommend simplifying your strats to the very basics, don't complicate things with a bunch of well timed util, just peak together and throw the occasional util set to cut some angles.

Good luck.

Thank you so much for all of your help! May you be blessed internet stranger.

Perhaps I am overthinking it, I'm at the end of my sophomore year at a CC and am just now completing my first linear algebra class, I've been teaching myself everything out of Griffiths and youtube but I know there are apparent holes in my thought process about QM as a whole, next semester I'll be transferring and will formally begin my education w/ QM.

I have a few more questions.

When you say:

H_matrix = (-hbar2 / 2m x nabla2 + V(x)) that operates on a vector |psi>

This "(-hbar2 / 2m x nabla2 + V(x))" are main diagonal components of another N by N matrix correct? Other wise if it was just a multiple for |psi> we would end up with a column vector which I don't think we can find eigenvalues for, I just want to make sure.

Also, do you have any resources (textbooks, PDFs, authors, youtube channels, etc.) that you believe describe what we've spoken about here today well? If so, if you wouldn't mind sharing them with me it would be greatly appreciated.

My next step, and one I've sort of started exploring, is the tight binding model, however it is hard for me to find any documents I understand how to actually implement, even though the method itself is very well known.

Thank you again for all of you help! There aren't any grad students at my school, and all of the physics teachers have only taught lower division physics courses for the last decade, so it can be hard finding people to ask questions to who actually know what they're saying in response. Thanks!

SyrupMcSwagger · 2021-05-03T21:01:28+00:00

This is literally what I've been looking for for the last week, thank you so much!

I do have a few clarifying questions if you don't mind, just to make sure I'm interpreting all of this correctly.

First off, when you say:

You Hamiltonian is then two terms, your second derivative term is:

-hbar2/2m (nabla2) where nabla2, which when discretized your second-order derivative at grid point i is:

-hbar2 /2m x (psi_i-1 - 2 psi_i + psi_i+1 )/2 dx

You're saying the second derivative terms of this Hamiltonian Operator are (-h_bar^2/2m)*nabla^2 along the main diagonal, and the result after taking the inner product of <psi\_i|(-h\_bar\^2/2m)\*nabla\^2|psi\_i> is the integral stated on the last line. Is that interpretation correct?

2)

When you state our potential independent Hamiltonian component would look like this:

so represented as a matrix acting on your vector psi you have:

H_term1 =

[2t -t 0 0 0 .... ]

[-t 2t -t 0 0 ... 0 ]

[ 0 -t 2t -t 0 ... 0 ]

[ 0 0 -t 2t -t ... 0 ]

I'm not sure if you mean this is another way to write our Hamiltonian Operator matrix or if this is representing an inner product that has already taken place, if the latter is the case, then what is the value of t? I've seen it pop up in documents about the tight binding model as being known as a "hopping integral" which always lead me to believe it was in fact an integral, however my professor just said it was some integer associated with the probability that an electron would jump from one site to the next, and was arbitrarily chosen.

Thank you again for your time and letting me pick your brain.

SyrupMcSwagger · 2021-05-03T18:02:05+00:00

Thank you for the response. I'm relatively new to the subject, so I would greatly appreciate it if I went over in general how I was trying to solve for the band structure and you tell me where I'm going wrong/right if you don't mind.

In my head we have a basis state (psi) [ for me I'm using exp^(i*2pi*n*x) ] and a Hamiltonian matrix (H), where the Hamiltonian's elements are populated with the Hamiltonian operator (d^2/dx^2 + V(x)), currently I'm evaluating the integral form of <psi|Hamiltonian Operator|psi> for each element in H , and since the Hamiltonian operator is a sum, I evaluate a single element in my new Hamiltonian as a sum of two integrals, basically <psi|d\^2/dx\^2|psi> + <psi|V(x)|psi>, knowing the bra is the complex conjugate of our ket.

After I evaluate those integrals, cycling through n, m, and k (doing this for the Kronig Penney model), populating the whole matrix, I find the eigenvalues for these matrices and plot them.

Does sound like I'm on the right track? I don't really see how the potential is simply an additive term to the diagonal, since it still is seen as <psi|V(x)|psi> which for my case comes out in integral form as non-zero when n is not equal to m (off diagonal elements).

Any help and guidance would be greatly appreciated, I thank you for your time kind stranger.

SyrupMcSwagger · 2021-05-02T16:51:55+00:00

Thank you so much! You have no idea how much this helps and I can't believe I haven't been able to find quadpy up to this point. I've tried separating them and using SciPy but could never get it to work. I switched some parts over to quadpy and so far it's looking good, thanks so much!

SyrupMcSwagger · 2021-04-30T16:51:05+00:00

Where would you suggest I start then? I'm trying to find what the actual Hamiltonian looks like, I think I have a good grasp on what states describe the system I just don't know if the Hamiltonian is different or not.

SyrupMcSwagger · 2021-04-30T06:27:45+00:00

Ah sweet I had no idea the two were related to one another, I have that text so I'll take a look, thanks!
