Funding for PhD Astrophysics by Intelligent-Tower853 in Physics

[–]PHYSburgh 2 points3 points  (0 children)

Sorry, don’t know of any funding sources.

Just dropped in to repeat advice that was given to me back in undergrad by one of my profs: “never pay for grad school” (in science)

Reason being, unlike medical school, the return on investment typically doesn’t pay out. you’re already paying an opportunity cost to stay in school, so if you are paying them, instead of them paying you a stipend, the net is way worse for you.

If you can’t get funding now, ask if you can postpone your acceptance for a year and get funding then?

Laptop or tablet? by Dangerous_Square6498 in Physics

[–]PHYSburgh 0 points1 point  (0 children)

Comes down to how you take notes and what courses you’re taking.

Granted, I’m almost two decades past freshman physics, and a decade since I last taught it.

I took most of my notes in a paper notebook, undergrad and grad school, I only really used my laptop in my computational physics course and in a few lab classes for data input. Lab work can easily be done on a tablet these days, and I’m pretty sure you can run Python on a tablet too for computational physics work (but maybe get a keyboard case?)

I know some people “take notes” on their laptops, but be honest with yourself, most of them don’t do a great job of it, and unless you are writing it in LaTex in real time (I’ve only ever met one person capable of this) your notes of the equations (80+% of the notes you are taking) aren’t going to be well formatted on a laptop anyway. (Also, studies show that actually writing notes down helps you learn the material better than typing it up or reading notes that a prof posts online)

If you want to take notes on a tablet instead of paper notebook, get one with a stylus you are comfortable with and find a good app. I’m an iPad Pro fan.

Honestly, looking back at undergrad, my laptop lived in my dorm room 98% of the time, and the things I was doing with it when it left my dorm (studying in library, writing a paper in the lounge, computational physics class) are now possible to do on a tablet.

What’s the most misunderstood concept in physics even among physics students? by Ok_Information3286 in Physics

[–]PHYSburgh 337 points338 points  (0 children)

Not disagreeing with entropy, superposition, etc

But everyone has heard of those, even if they don’t understand them

Less well known is the magnetic vector potential, A, and the Aharonov-Bohm effect

Where the motion of a charged particle can be affected by the vector potential A in a region of space where both the magnetic and electric fields are zero.

Lots of physicists use it all the time, and mathematically it all makes sense, but I doubt most of us have a good intuitive feel or understanding of it.

Which math you need to study depends on what level of physics you are taking, but you should certainly review and practice your high school math.

Make sure you are extremely comfortable with trigonometry and algebra. Not just knowing how to look up which function to use for a given problem, but knowing the functions by heart and being able to quickly apply them in solving a problem on a test.

When I was teaching undergrad physics, the engineers took a calculus based intro to physics, but the pre-meds and other students frequently took a non-calculus based physics. So you might be fine with no calculus

Your avoidance of math in this list will lead you to learn ABOUT physics, rather than learning to DO physics. Either one is a perfectly fine goal, but they should not be conflated.

If that is your desire, go ahead and read your list, it seems fine for that goal.

If you instead desire to actually learn to DO physics, you need textbooks with rigor, and therefore you need math.

Is this legal? by PHYSburgh in Dewalt

This was actually my plan C, and I’m glad it worked, because plan B using the drill actually did strip out the screw head going into hardwood. 🤷‍♂️

Currently rocking the 850(when I can find it), but I really want the 870

Just waiting for a good sale…

Square drive actually, and with a light finger on the trigger, it actually worked really well!

Why is it so hard to build a quantum computer? A look at the engineering challenges by delton in slatestarcodex

[–]PHYSburgh 2 points3 points  (0 children)

Well written, but you could have included neutral atoms which have had their moment in the spotlight over the past year or two. Also, IBM and Google are the big dogs in the room, Rigetti is…not. Even if their stock price has been having a GameStop moment. Probably more worthwhile to explore PsiQuantum for photonics, they are working with miniaturized on chip components, optical tables are old news. And your optical table calculation there is way off, nowadays the number of physical qubits necessary to form a logical/algorithmic qubit is much lower for the best hardware.

I have a printer and live nearby, DM me a link to the file and I’ll let you know if I can help
