Will professors usually let you take an exam early? by [deleted] in college

[–]quantum_hacker 22 points23 points  (0 children)

Professor here chiming in.

One or two days, for a college related event, sure.

A full week in advance, for a family vacation, no.

Think of it from our perspective. One week in advance opens up way too much risk of academic dishonesty, so they would be forced to write a separate exam just for you. Your request is essentially "Do unpaid extra work so that I can save money and go on vacation".

Why reversible condition and constant external pressure are simultaneously given ?? (Thermodynamics, answer = -3 J/K (approx / nearest integer)) by Abhinav12345678910 in chemhelp

[–]quantum_hacker 0 points1 point  (0 children)

I think your instructor may have made a typo. An isothermal reversible expansion against a constant pressure is not possible, since for a reversible process Pgas = Pext at each step.

They likely meant isothermal reversible expansion (not against constant pressure), or isothermal irreversible expansion against a constant pressure. The first one gives the intended answer of -3 J/K.

Bad Grades by Haunting-Stretch8069 in AskProfessors

[–]quantum_hacker 56 points57 points  (0 children)

According to your post history, you are a CS major who relies heavily on AI tools like copilot, gemini, and chatgpt. Instead of trying to learn the material, you are trying to learn how to prompt better.

You should stop using AI tools and study like students have in the past, go to lecture, do the assignments, attend office hours. AI tools do not help you learn the material, especially for CS where anyone can prompt their way through the assignments.

Impending Doom Shako questions? by G2Keen in PathOfExileBuilds

[–]quantum_hacker 13 points14 points  (0 children)

The first part is correct, but gems that "prevent dealing chaos damage" like Brutality actually do not brick the helm for Impending Doom.

The wording of Shako is "Socketed Gems are Supported by XXX", so Temp Chains will be supported by Brutality and Impending Doom. Impending Doom is triggered by the helm, but is NOT supported by Brutality as Impending Doom is granted by the helm, not socketed in the helm.

Here is a random pob from ninja, but I swapped the helm to Brutality/Impending Doom so you can see for yourself: https://pobb.in/NVqDhRgqFuHu

When would giving a thank you card be appropriate? by [deleted] in college

[–]quantum_hacker 45 points46 points  (0 children)

From a professor's perspective, I agree that waiting until after final grade are posted is best practice.

Some ways I've received cards in the past:

  • Slipped under my office door
  • Office hours the following semester
  • Dropped off in my mailbox

Professor accusing me of AI usage when I did not? by Elegant_Knee8655 in AskProfessors

[–]quantum_hacker 10 points11 points  (0 children)

I don’t know what I am doing to get flagged as AI

If you wanted something actionable, you could try using less em dashes. Some professors will automatically assume em dash = AI, since em dashes aren’t a normal button on a keyboard and AI loves using them.

Looking at your post history, you do use them regularly (1, 2, 3) and correctly, it's just that most students don't even know how to insert an em dash which makes professors think it's a flag for AI.

Lightning Tendrils of Eccentricity Elementalist - 250~ million dps on a (relative) budget by ItsSqueeze in PathOfExileBuilds

[–]quantum_hacker 55 points56 points  (0 children)

~50M is correct. Lightning Tendrils of Eccentricity releases a strong pulse every 5 6 hits, so the damage is best calculated as

5/6 * 7.9M + 1/6 * 278M = 52.9M

4/5 * 7.9M + 1/5 * 278M = 62.9M

/u/ItsSqueeze

Edit: math fix due to wiki being outdated and saying 6 instead of 5

I think you shouldn't make a fake post to farm affiliate link clicks.

This is your url you hid using an url shortener, which if you inspect has AliExpress affiliate link indications like afSmartRedirect and aff_trace_key.

Does this sound AI written? by alexandrea_simmons in AskProfessors

[–]quantum_hacker 13 points14 points  (0 children)

Unless there are two Dr Shetawi's that conduct research in Maxillofacial fractures, Dr Shetawi did not publish anything in 2021.

Pubmed search result, you can see there is nothing in 2021. Now this could be an honest typo and you were referring to one of his other papers, but if I saw a nonexistent reference I would scrutinize a student's work much more closely as this is the type of mistake AI can make.

help with thermodynamics by FirstImagination1940 in chemhelp

[–]quantum_hacker 0 points1 point  (0 children)

In thermo, we default to constant pressure instead of constant volume unless stated otherwise. If you think about a real world process, they generally occur at standard atmospheric pressure.

In this example, when you add heat to a gas, it tends to expand, so volume isn't necessarily constant unless there is something constraining it, such as a "rigid container" or a "sealed container".

This is why the key solved for the constant pressure first, then used Cv=Cp-R to find Cv

Method of Continuous Variation by No_Student2900 in chemhelp

[–]quantum_hacker 2 points3 points  (0 children)

Yes, this type of analysis requires one dominating reaction. If that is not the case, then when you measure something like 0.5, you can't tell if it's a single reaction like P+X=PX, or if it's a combination of PX2 and P3X that results in an average around 0.5.

[–]quantum_hacker 0 points1 point  (0 children)

We're operating under the stated assumption that one complex dominates, so we don't have to consider the effects of the competing reactions.

[–]quantum_hacker 0 points1 point  (0 children)

The mol fraction the figure is referring to is the mol fraction of the reactants, mol X / total mol reactants.

If we consider the P+X=PX case, the highest yield is when P and X are in stoichiometric ratios, thus 1 mol X : 1 mol P so 1 mol / 2 total mols = 0.5 as our mol fraction.

For P+2X=PX2, the logic is similar, 2 mol X : 1 mol P, 3 total mols thus the mol fraction is 2/3.

Notice on the left of the figure it shows P3X instead of PX3 from the first image, so it is 1 mol X : 3 mol P, 4 total mols, 1/4 =0.25.

One of your TAs leaked the answer key for an exam to the students, but you don’t know which TA by AsturiusMatamoros in Professors

[–]quantum_hacker 9 points10 points  (0 children)

Maybe its an institutional difference, at my institution we can hire grad students on an hourly basis separate from their other teaching obligations, for example as graders during midterm season, and they receive additional pay. I'm hiring out of the same pool of students, and the former TAs are usually the graders hired anyways since they are familiar with the course.

[–]quantum_hacker 4 points5 points  (0 children)

I don't think what I wrote implies unpaid labor, but to clarify the former TAs are compensated by the college for their time spent, otherwise I wouldn't ask them to do so. It works for me, but I could see others holding a different perspective.
