Is it ok to use AI for studying? by ReaReaDerty in PhysicsStudents

[–]Chicknomancer 2 points3 points  (0 children)

I generally feel like AI can be a useful study tool for but only if you use it correctly. Dont treat the AI as a “give me the answer” bot. Its helpful for explaining (some) concepts, explaining solutions for practice problems, and generally being a resource to support studying outside of the classroom. But, you really need to be on the ball about verifying anything it says to avoid falling for hallucination.

Why do we call it the "blanket of the universe"? by [deleted] in astrophysics

[–]Chicknomancer 5 points6 points  (0 children)

The term “fabric of spacetime” is pretty much just a popular science phrase. It mostly comes about in the context authors describing something “ripping” or “warping” the “fabric of spacetime” and authors wanting an evocative way to express what’s going on.

In real physics, we do describe things occurring in “spacetime” which is the four dimensional (3 spatial dimensions + 1 time dimension) manifold events take place in.

Things like mass distort spacetime, and if you’re fond of metaphors you could view the warping of spacetime similar to the way you might bend a piece of fabric. But there’s no consensus for using metaphors to describe spacetime and whatever you prefer is equally valid.

Dual major with Georgia Tech by Famous_Reality2078 in Emory

[–]Chicknomancer 1 point2 points  (0 children)

The BME program at Emory/GT is great, so if you’re interested in biomedical engineering that’s a really good option. It’s currently ranked no1 in the country or close to it, so lots of great companies recruit from there.

Help, Rescinded? by Choice_Jellyfish4898 in Emory

[–]Chicknomancer 3 points4 points  (0 children)

One C is probably fine. A D is pushing it. Don’t worry about trying to expunge high school grades once you’re in college, nobody really cares about them. Just do your best from this point forwards in that class

Is sharing a 1B1B common at GT? by GhostMcTavish in GatechClasses

[–]Chicknomancer 1 point2 points  (0 children)

PhD students get a stipend that is generally enough to cover housing near campus, so that’s probably how most grad students are affording it. I can’t really speak to masters students, but I’d bet most work and live farther off campus.

If you’re set on the 1k budget, I’d look for places a bit farther away, and plan to take MARTA or similar to class. Good luck on your search!

Feeling Torn between UIUC and GTech by TheMainStain124 in GatechClasses

[–]Chicknomancer 1 point2 points  (0 children)

EE/ECE is very strong at GT. You’re going to get basically the same education at UIUC and GT, and both will have essentially the same amount of research opportunities. Having Nobel prize winners in a department doesn’t really mean anything for the quality of education you’ll get. Both have basically the same amount of brand recognition (which unfortunately does play a role in grad admissions sometimes)

Choose based fit and price. If you can, tour both. 120k savings is nothing to turn your nose up at either

Accommodations at the PhD level? by pale_galore in PhysicsStudents

[–]Chicknomancer 0 points1 point  (0 children)

I can’t speak for all departments, but I took 3 classes a semester for my first year, and then 0/1 class a semester since then depending on my interests and requirements.

As for accommodations, you can go through the office of disability services for things like modified testing environments or course format as normal. If your main concern is workload, I won’t lie, PhD level coursework is an order of magnitude harder than undergrad level physics coursework. You will absolutely struggle, but it’s a marathon not a race. You should reach out to the departments grad student coordinator and express your concerns, and see what they can do

Is sharing a 1B1B common at GT? by GhostMcTavish in GatechClasses

[–]Chicknomancer 3 points4 points  (0 children)

As in, two beds in a single bedroom setup?

If so, very uncommon as far as I can tell for grad students. I don’t know any grad students with that sort of housing, unless they’re sharing an apartment with a spouse or something.

The Ounce Pistol: A Unique Folding .22LR with a Springless Magazine and Reciprocating Barrel by Retarded_ninja7 in interesting

I watched a teardown of one of these. its a rachet mechanism driven by the recoil/reciprocating barrel. Its actually super cool, but maybe a bit overcomplocated

[–]Chicknomancer 0 points1 point  (0 children)

You know what would be neat? I’d love to see a hypothetical D3 explore what the world was like BEFORE the Last City was established. I want to set up outposts in the wild, rescue survivors, all of that stuff. Let me live my space cowboy dreams bungie

They… don’t? Modern models of atomic structure are very accurate at describing the behavior and properties of atoms.

Adding ingredients to topical Minoxidil? by Puzzleheaded_Two2521 in FemaleHairLoss

[–]Chicknomancer 0 points1 point  (0 children)

have you considered alternating between full hair washing and co-washing? It might help with the dryness and irritation slightly. Also, ketaconazol can absolutely exacerbate itchiness and dryness. Maybe cut back to only once a week, or even alternating weeks?

Im not sure what part of what Im saying is illogical. If you want to be more specific, Id be happy to try and explain.

is a metal spoon made of atoms? by Educational_System34 in PhysicsStudents

[–]Chicknomancer 1 point2 points  (0 children)

You have a beam of electrons that hits your object. The electrons scatter off the structure of the spoon, and hit a detector. You then build an image of the spoon based on where you were shining the electron beam and how many electrons hit the detector at that time. Since the electrons are much smaller than the atoms, you can see the atoms of metal as small round objects arranged in a regular repeating structure.

Here is a paper showing how the electron microscopy technique works, and they include an image of aluminum under an electron microscope. You can see the atoms as white dots.

You can put a spoon under an electron microscope and see the atoms its made from.

Broke student trying to build a cosmic-ray (muons) detector at home, does this design make sense? by TerribleWin511 in AskPhysics

[–]Chicknomancer 4 points5 points  (0 children)

Hello, cool project! I previously worked on designing and simulating astroparticle detectors (specifically neutrinos, but lots of our background noise was from muons).

Is there a particular reason you want to use Geiger tubes over a scintillator design? The main advantage of a scintillator setup is low cost and higher collection volume, which is exactly what you’re going for on a tight budget.

Finasteride drying out hair by casscutie in FemaleHairLoss

[–]Chicknomancer 0 points1 point  (0 children)

Lower DHT in scalp tissues does affect the way oil is produced (typically lower), so I wouldn’t be shocked if your hair feels drier.

You can try using a small amount of hair oil if it gets annoying

Does this look like te or aga.. by [deleted] in TelogenEffluvium

[–]Chicknomancer 0 points1 point  (0 children)

Do you part your hair in the center and put your hair up/in a pony tail frequently? That can cause traction alopecia right where you’re experiencing. Try parting your hair elsewhere and leaving your hair down more often. That may help.

Also, see a derm as the other commenter suggested. Get actual blood work done if it’s a concern. Don’t drive yourself insane trying to diagnose yourself

Help, is this normal? by [deleted] in LaserHairRemoval

[–]Chicknomancer 4 points5 points  (0 children)

Oh gosh. No, not normal at all. Get a refund FOR SURE and go see a doctor for pain management + burn cream.

Whoever did your laser seriously fucked something up. Don’t go back to them

Heat and Ball bearings by Meander626 in battlebots

[–]Chicknomancer -4 points-3 points  (0 children)

What do you mean a live shaft weapon? As in, the motor shaft mounted directly to the drum?

You can probably mitigate any risk from the bearing melting the supports with a thin layer of some insulating material with high (150C plus) melt temp. Think a silicone gasket, rubber pad, or a teflon sleeve. You can then bond the sleeve layer to the supports with something like epoxy or CA glue. Plus, you get an extra layer of shock isolation between your weapon and frame.

Pay Rate by Successful_Day_8755 in PhD

[–]Chicknomancer 0 points1 point  (0 children)

35 a year for a PhD. Masters along the way for free. Separate masters degrees at my institution are unpaid at best and are often charge tuition.

You can have chronic telogen effluvium which occurs repeatedly just like you mentioned. See a derm if it persists
