You don’t wear gloves when you work with HF? You are banned from my lab. 8 mil nitrile. Always check for cracks and pinholes before use.
Conventional wisdom is to not wear gloves when working with HF, as pedvide points out. It may not be to your advantage to ban people like pedvide's advisor from your lab, especially if at some point they're refereeing your papers—though, at least from my point of view, there should be no such personal-offense considerations involved, it would be unsurprising if someone were insufficiently detached for such a personal…
My teaching lab was for undergraduates who were etching oxide off of silicon wafers in a big old tub of hf. We’d have them wear a big thick apron and massive gloves; this is not an occasion requiring dexterity, and it’s one with a high potential for inadvertent splashes. We never had an exposure in the years I was there, although a grad student in a research lab got careless and took a cold, rusty shower.

Yeah? What "life lesson" does the dean think you're going to learn from that? That authority figures cannot be trusted because they will hurt you with bureaucratic stupidity. Does the dean, as an authority figure, really want that to be the lesson you learn?
A kid might see it in terms of "authority figures," but live long enough and you'll understand it's everyone. Not just your professors and bosses, but your subordinates, your friends, your lovers, even your children will judge you unjustly from time to time. But that doesn't mean the world is poison and existence is a curse. It just means you have to learn to get by despite other people's imperfections the same way t…
Except that you can't get by if the other person is an authority figure and the imperfection is throwing you under the bus.
Your statement makes no sense in the context you're answering to.

Sort of like the first debugging tip here: https://news.ycombinator.com/item?id=42682602
> 1. Understand the system: Read the manual, read everything in depth, know the fundamentals, know the road map, understand your tools, and look up the details. Maybe? Although it seems more like it's actually #5: > 5. Change one thing at a time: Isolate the key factor, grab the brass bar with both hands (understand what's wrong before fixing), change one test at a time, compare it with a good one, and determine what…
Odd. When I look at it, the first item is my own suggestion for debugging:
> In my experience, the most pernicious temptation is to take the buggy, non-working code you have now and to try to modify it with "fixes" until the code works. In my experience, you often cannot get broken code to become working code because there are too many possible changes to make. In my view, it is much easier to break working code than it is to fix broken code.

I think we may have just had different interpretations of "here" in this instance. I took it to mean the article at the link, while you meant the comment that you authored?
I will justify my interpretation because saying "first" primed me to expect a list and the linked comment (and portion quoted) only suggests rewriting, while the article at the link mentions 9 rules to keep in mind during debugging.

It's a general problem with large bureaucracies. If you're a cog in the machine, the safest way is to always stick to the rules, and avoid any situation where one has to exercise discretion, since any personal judgment comes with potential personal responsibility down the line.
It bugs me that oftentimes there appear to be nothing but cogs (e.g. Intel)
That shouldn't be surprising at all, since that is the safest arrangement for everyone, and therefore the system will tend to approximate it closely in the long term.

Interesting. If that is correct and you take OPs value, 6.8 / 5 * 7 = 9.5 which is pretty damn close. So his failed grade was for the only non-cheated result?
One ambiguity for anyone reading this in future would be... I would hope that both experiments already had worked in the impact of the angle of the board on the gravitational force, and the 6.8 the op turned in was with that taken into account. But without taking into account inertia and friction.
I feel like this is one I'm going to have to try at home.
Re: Electron band structure in germanium, my ass (2001)
#428One of my Core Memories when it comes to science, science education, and education in general was in my high school physics class, where we had to do an experiment to determine the gravitational acceleration of Earth. This was done via the following mechanism: Roll a ball off of a standard classroom table. Use a 1990s wristwatch's stopwatch mechanism to start the clock when the ball rolls of the table. Stop the stopw…
Just registering my experience, which was mostly good in principle.
I took my physics/chem labs at a not particularly good university, and got points for having valid calculations, whether or not they matched the correct values. I felt that the labs themselves were a little bit patronizing and a waste of time, but at least they were designed in the direction of making us perform experiments and do measurements.

Out of curiosity, do you have a specific goal or outcome in mind in this exchange? I have tried to determine what your and your sparring partner's objectives are, and I admit it is difficult to discern.
>Out of curiosity, do you have a specific goal or outcome in mind in this exchange? I have tried to determine what your and your sparring partner's objectives are, and I admit it is difficult to discern. Thank you for asking! I'm most curious in figuring out ways to bridge the communication gap that is manifesting in this discussion. The gap is as follows: multiple people have objected to the remark of /user/ninetyni…
I might have missed a point you stated, but a few thoughts:
1. I am not sure the issue is double empathy
2. A group of people could see holding a performance standard as attacking livelihood. I believe this view ignores that the teacher chose to mis-grade a paper, so the jeopardy to livelihood is on the teacher themselves -- assuming the standard and expectation is fair. An organization needs to hire and be willing to fire based on its values.
3. Tone policing of text has a long history on the internet. Five years ago we'd accuse tone policing enforcers of expecting privilege where none should be expected if you seek a meeting of the minds. Tone policing is a weird mix of shibboleth and inability to simply state: "I disagree" and disengaging from a conversation.
