Assuming this is real, it looks like he measured some high quality noise. No way the resistivity would jump 2x over 5 degrees and stay constant at constant temperature (the biggest suspect according to his own confessions).

When you do it right you get this sort of picture. https://pdfs.semanticscholar.org/3753/2b8a21825d66633f33684a...

I guess this must be from '99. Consequently the author went to get his Masters and PhD in CS.[0]

Having gone through a similar ordeal and frustration at the end of my uni career, in the end I went out with the highest admiration for the experimentalists and their tech staff.

Pretty funny, but what seemed disturbingly true: > Going into physics was the biggest mistake of my life. I should've declared CS. I still wouldn't have any women, but at least I'd be rolling in cash. I wish academia pays better.

It's not just the pay; the pressure as a graduate student and not-yet-tenured professor is immense. The darkly humorous "A (de)motivational letter", purportedly by one "Prof. Hardass Slavedriver", sums it up: https://lifesciencephdadventures.wordpress.com/2013/01/04/a-...

Exactly my experience back in the days doing the mandatory "advanced experimental physics laboratory semester" where you had to do like 14 vastly different experiment of the caliber described in that post in the course of one semester on old equipment that would break during the experiment, with less than motivated PhD students or post grads as teachers. Of the 14 experiments only two worked and we got the expected r…

> on old equipment that would break during the experiment

Isn’t that closer to the real conditions in a research lab?

I met some NASA scientists doing atmospheric sampling on a plane, and they had to accompany their equipment to manage any equipment glitches during the expensive sampling process (a custom modified 747 flying from Hawaii to New Zealand IIRC)

Yeah I don't quite understand how the physics curriculum is set. There is more and more physics discovered over time and yet the time you get to study remains the same. 4 years is not enough time to learn the math and physics you need to do anything real, not counting the other important stuff you need to do (like English comp and partying and getting your heart broken).

Heh this strikes me as funny. I remember studying hierarchical image classifiers... If you think physics changes fast you should check out CS sometime.

As is Mathematics.
