See section 5 on Kindle display measurements by optical coherence tomography. The Kaleido display is similar but with a matrix color filter layer. Those images weren't published.

A little off topic, but Figures 12 and 13 show optical coherence tomography images of Kindle Paperwhite display layers. The E-Ink, touch screen electrodes, and lightguide layers are shown.

A little off topic, but on the subject of E-Ink, here is an analysis of a Kindle display with optical coherence tomography images: https://arxiv.org/abs/1605.05174

"Optical teardown of a Kindle Paperwhite display by OCT": https://arxiv.org/abs/1605.05174
OCT = Optical Coherence Tomography
This paper shows what is going on inside the display.

Where does the data come from for this? The Gaia satellite database?

A little off-topic, but https://www.scanmytesla.com/ is a great automotive hack. Here is some data I collected with it: https://bartev.org/ and some data from a drag race with my Model 3: https://bartev.org/tesla-drag-race/

E-ink is a fascinating display technology. Here is an account of a non-destructive “teardown” of an E-ink display by optical coherence tomography (OCT): https://arxiv.org/ftp/arxiv/papers/1605/1605.05174.pdf

Here's what Richard Hamming has to say on the subject:
https://www.cs.virginia.edu/~robins/YouAndYourResearch.html
"Knowledge and productivity are like compound interest. Given two people of approximately the same ability and one person who works ten percent more than the other, the latter will more than twice outproduce the former. The more you know, the more you learn; the more you learn, the more you can do; the more you can do, the more the opportunity - it is very much like compound interest."
The payoff of working more is not linear.

That is what depression felt like to me as well. I’ve written a book about it, Can’t Be Trusted. It is a memoir about engineering, mental health, and aviation. Here is more information about me and my book: https://cantbetrusted.org/?page_id=262 As a laser engineer with an interest in computing, I think this book would be of interest to the tech community.
