Earlier quoted context omitted.

while we're on thin and japan companies, youtube taught me about Disco, the wafer slicing disc company. Such a "trivial" problem in definition yet very impressive when you think about it.

What I love most about these small engineering companies making high tech niche products is their no thrills, stuck in the 90's websites. Huge contrast to dark pattern based websites dedicated to selling stuff to consumers. I guess they just don't bother since it'll make no difference to their bottom line. They're well known in their niche and probably as the only go-to solution for this kind of problem, I imagine th…

Doctor Yueh put an object on the table between them - black, oblong, no larger than the end of Paul's thumb. "It is a very old Orange Catholic Bible made for space travelers. Not a filmbook, but actually printed on filament paper. It has its own magnifier and electrostatic charge system." He picked it up, demonstrated. "The book is held closed by the charge, which forces against spring-locked covers. You press the ed…

Here's the company Hidaka Washi mentioned in the article: https://www.hidakawashi.com/jp/paper-TENGU/index.html They make "tengu jo-shi" (典具帖紙), the world's thinnest paper, also called "the wings of a Mayfly". Around the beginning of the 20th century they achieved a thickness/thinness of 0.03 millimeters. The paper became popular for typewriter paper, as well as napkins, wrappers for precious stones, coffee filter, l…

There are many thinner materials : 10-micron aluminum foil is commonplace in households, and disposable plastic shopping bags are usually about the same thickness, while this paper is 20 microns. Any of these could fit Yueh's 1800-page book into the thickness of Paul's thumb, 18-36 mm. But typical gold leaf is 0.1 nanometers thick, a hundred times thinner. What's notable about this paper is that it's paper that thin.
