hahaa, I love it! That's right there is engineering and true work and dedication. Can hear the frustration and it's 100% warranted. I wish universities were better equipped for what you pay. Where is all that money going anyways? Leaking like free electrons?

The gym, I think. Usually the brand new buildings, too.

It’s going to the salaries of a few elite people in the university system. It’s not that far off from the wealth inequality of the real world.

So did you let this go without protest? Why not escalate it if it was clearly so unreasonable? Sounds like there was more nuance to the story.

"Escalating" in American high school is a good way to increase your consequences to no benefit.

I escalated a very similar thing with a college professor--in a social sciences class.

She did not update my score, she argued a while in front of class, and when she lost the argument, said I could take it up with her supervisor.

I declined (it was one question on a larger test)

> From grade school on, you are graded on whether or not the grading authority likes the results you got. I took an exam in a high school science class where I answered a question with the textbook's definition exactly as presented in the textbook, complete with the page number the definition was found on. I knew a bit about the topic, so I then cited outside scientific sources that explained why the definition was i…

> he was angry, he marked it wrong. That’s grounds for termination to me. Seriously. I would put this man out of a job and endanger the livelihood of him and his family for this kind of shit.

And if you CAN'T terminate because of admitted emotional grading, the system is too tightly captured by outside interests to the detriment of the client: the student and society.

A teacher is a professional entrusted with the most important responsibility society can offer: training and educating the next generation. It must adhere to the highest of professional standards and expectations.

That we don't pay enough to require that without reserve is a statement on our societal priorities, and disconnected from the expectations that should hold.

One 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…

Having recently gotten into quantum and listening to a lot of audiobooks on the history of it, that’s one of biggest takeaways for me. So many major advances in theory that languished for years because of the politics of the day of the personal opinions of their advisor, only for a physicist with greater standing to rediscover the same thing later and finally get it some attention. (Hugh Everett and David Bohm being two examples)

I spent a good minute looking at the exponential in graph, ignoring all the actual data points, thinking to myself that the experiment does show an exponential relation. Where's the lie? Guess that's the power pictures have over words.

> ignoring all the actual data points

Well that's your problem.

The line is the predicted, not actual. How would you derive that line from plot of noise?

>> I drew an exponential through my noise.

The issue is that there was supposed to be a curve according to his reading, but the actual had no measurable trend. It's possible that the data was measured on the wrong scale. If you zoom out, those noise plots become a line segment. Then again, the predictable line is on the same scale (and we're assuming that it's correct according to his reading or the best he could fit) so zooming out would probably be a different form of lying with statistics via overfitting.

I TAd a semiconductor fabrication lab class 20-odd years ago. Mostly it was about making sure the students had the absolute fear of God put into them about working with HF, but there was also a bit at the end where you actually got to do a voltage sweep and characterize your transistor. If in fact you had made a transistor rather than a needlessly complicated resistor. The other TAs and I passed this paper around and thought it was just hilarious.

Agreed. Like this is fraud level bs that’s happening and people are voting me down.

I think it’s because this kind of stuff is common. People have done fraudulent stuff and they don’t agree it’s a fireable offense. Understandable. I still would endanger someone’s livelihood for this. Poor performance I would think twice and go through all measures possible to improve performance including putting them in a position where they can excel. Poor performance does not justify endangering the livelihood of a person or their family but this fraudulent bs of being angry and marking something wrong. That’s just malice.

That's a poor way to measure g. In multiple schools I went to, the standard was to measure g via a pendulum (I think measuring the period).

I measured a 9.86[1] :-) Mostly dumb luck. But most people in the class would get decently close (9-10.5).

[1] The correct value is closer to 9.81.

I took some effort to change my research interest from computer vision to DFT calculation in quantum chemistry. Honestly, I'm kind of frustrated now, too many work is close-source in this area. The research paper will tell you everything except how to reproduce this work in minimal effort, it's like they are hiding something. They also using a `Origin` to plot and MS Word to write paper, which is also non-free licens…

> The research paper will tell you everything except how to reproduce this work in minimal effort, it's like they are hiding something.

They are. I used to work in an adjacent field. Everyone was open about doing it - they're competing with others for grants, and worry that if they reveal the secret sauce, others will move faster than they can.

You can say you performed a DFT calculation to get the result, but anyone who's studied these types of simulations/calculations knows that it's highly nontrivial to implement, with lots of coding and numerical tricks involved. So it's extremely hard to reproduce if you don't have detailed access to the algorithms.
