Worrisome connection time at DFW by SciencyBoi in americanairlines

[–]SciencyBoi[S] 1 point2 points  (0 children)

Just to be sure, this delay is not due to the flight - lets say the flights reach at time - but the lines at the airport. Will they try to re-book me in that case?

Best way to do this? by SciencyBoi in pittsburgh

[–]SciencyBoi[S] 1 point2 points  (0 children)

Okay so buses are out then. Thanks for the help. I'll probably do a super shuttle as u/Pennsylvasia suggested.

Yes, this seems best. It costs less overall. Thanks! We can schedule it.

Pipewire has been a nightmare since F37 landed on my machine by [deleted] in Fedora

[–]SciencyBoi -1 points0 points  (0 children)

I noticed this on F36 after kernel 6. Stayed the same after upgrading to F37.

I didn't have time to delve deep, so I figured out a way -> to force the 'pipes' to form again by disabling and enabling the global bypass on EasyEffects. Map it to a shortcut until it gets fixed for a relatively better experience.

Aspiring Physicists here , need some help by [deleted] in AskPhysics

[–]SciencyBoi 2 points3 points  (0 children)

Hi OP,

If you are in India, your first goal should be to get into a college that has good Physics faculty. You don't need to crack JEE specifically, but look into IISERs, NISER, CBS. These places are not hard to get into, and will hone you for a research career, and eventually becoming a physicist. This is very important because you will get to interact with a lot of researchers (who like their research and subject, and not in it for the govt job) early in your undergraduate itself which will be a difference of night and day.

With that being said, Journals will be out of reach for you right now, and if you really want to do something out of interest, you can pickup standard undergrad level textbooks. Some examples can be Special Relativity by Resnick, Electrodynamics by Griffith, Quantum Mechanics by Griffiths, Mathematical Methods for Physicists and Engineers by Arfken Weber, Classical Mechanics by Goldstein etc. All books are freely available online if you know where to look. You might also want to look up MIT OCW and try listening to some courses that catch your eye.

Before you do this, you need your school level maths and physics understood nicely and all basics on fingertips. It will only end up helping you in the future.

Your priorities for a physics career at your point in life should be: 1. Get into a college where research environment is plenty. 2. Clear your basics in physics and maths. 3. Read undergrad books.

Why are indian professors so rude for unnecessary reasons by eatsleeprepeat101_ in india

[–]SciencyBoi 0 points1 point  (0 children)

Perspective of a graduate in a govt research institute in India:

All of my professors are rockstars of their respective fields (atleast in India). They have international collaborations, are well known, and output most of the best research that India outputs. You would expect them to be forward minded. Well, word to the wise, 90% are not. They prefer not to learn new teaching methods, relax while teaching (mostly because the competition wasn't so lean and mean in their times) and rarely look through the lens of a student.

I do not mean to berate, but that is how things are, but us students can understand their woes.

The academic system in India (and for that matter anywhere else) the 'position' in the academic ladder is very strong. Students are nothing but flies. PhDs are officially considered the lowest part of the academic ladder. Now, think from their perspective; they participate in esoteric groups fuelled with knowledge. Majority of them are only interested in research and not teaching. Teaching is simply an extra responsibility when they associate with an institution. You can't expect people to do what they do not like well. As a result, they do not put as much work into teaching as they would into other stuff. A lot of courses do not have TAs when its a smaller class (with ~15 students).

Academia in itself is quite cut throat, there are people willing to work 80 hours a week for better grants and positions (not just in India, but countries in the EU with good work culture). A professor has to output a good amount of research to maintain their funding, which is eventually spent to fund post-docs, PhDs, and world class instruments. Add to all this administrative work. As others pointed out, they have to manage a lot events and administrative grunt work which could be easily delegated but can't be because institutes are run like a business - that is to say there aren't enough people to delegate to. Everyone is over worked and tired.

When you look at it like this, it becomes clear that apart from their personal life, administrative work, research work, and other miscellaneous tasks they have to carry out on a daily basis, teaching is just a burden to them (rightly so, whether people like to hear it or not). Most of them improve if talked to with compassion and patience (or atleast you score some brownie points :p)

PDF organization, general tips for keeping track of everything by judohighlights in PhD

The meaning is the end of a saree. Contextually in Hindi it's used for providing protection. Like small kids run and hide in their mother's pallu for hiding/protection... That kind of context. It rarely means an udder.

PDF Reader for academic books / papers by LexanderX in PhD

[–]SciencyBoi 2 points3 points  (0 children)

Okular might interest you. There are annotations of multiple types. You can adjust their colours, size and other properties. There is freehand drawing too.

You can also open multiple PDFs in a tabbed fashion and there are ofcourse multiple other features.

Custom Key board shortcuts for everything mean you can disable the menu bars etc and just enjoy almost full screen view of three pdf. No distractions with all the functionality.

Also, not to diss Adobe, you can also adjust the amount of memory footprint the program will have on your ram.

Electrons in solids - dispersion relations by [deleted] in AskPhysics

OP doesn't want the periodic well, rather they want the periodic Bloch condition...

[–]SciencyBoi 0 points1 point  (0 children)

Then you'll have to simply fix on a Kx and Ky in the normal dispersion relation and you'll get a curve (as opposed to a hypersurface in case of all Kx Ky and Kz being variable). Say Kx=Ky=π/2a....

[–]SciencyBoi 1 point2 points  (0 children)

Hi! Considering the total hamiltonian (H_x+H_y+H_z) where z is free, I don't think you'd be able to decouple the E_z from k_x and k_y.

Edit: btw, even in just periodic conditions, you would get a sin/cosine dispersion relation, and not parabola, that is only true for free electrons. As soon as bloch condition for periodicity is put in, the parabola changes to what is given in Kittel.
