What should science cost?

I would agree with you about growing costs for equipment in trendy "big science" (dark mater, hot fusion, gravity waves, accelerators), and I see this trend in military domain, like in IT in old-fashioned companies, like in nuclear industry... It is aggravated by a growing increase of regulation.
It seems that some domains push providers to improves performances to the point nobody can buy the product, but it is really perfect. I've heard that for nuclear reactors (they can resist to anything, but nobody can afford them), for tanks (they are smart, agile, p... (read more)

There are some analysis about why democracy, modernity appeared in Europe, earlier in Greece, and there are two related analysis.

One is by  David Cosandey, "Le secret de l’Occident. Vers une théorie générale du progrès
scientifique, "

You can translate this related presentation to have a quick vision:

He proposes 2 concepts, one is "articulated thalassography", a measurement I've seen in fractal theory, comparing the length of the coast with surface of the country that can be reasonably defended...

AMA: Jason Crawford, The Roots of Progress

I have a very technical question about the history of semiconductors.
I've read long ago, that in the 20s Germanium conductance was a mystery, because of parasitic PN junctions caused by contamination and various metallurgical uncontrolled differences...

It seems that some researchers had observed PN diode effects, but also, unable to explain it, have kept the measurement in their drawer... Is there any serious report about that dark age of germanium PN junction ?

More generally, I would like to understand the really underground story of early semiconductors ... (read more)
