Fields, Factories, and Workshops is an 1899 book by anarchist Peter Kropotkin that discusses the decentralization of industries, possibilities of agriculture, and uses of small industries. Before this book on economics, Kropotkin had been known for his militant activity in behalf of international anarchism and writings...

The risk assessment of different titanium dioxide nanomaterials in sunscreen is currently evolving as nano-sized TiO is different from the well-known micronized form. The rutile form is generally used in cosmetic and sunscreen products due to it not possessing any observed ability to damage the skin under normal condit...

Almost entirely self-taught in modern formal logic, Prior published four major papers on logic in 1952, when he was 38 years of age, shortly after discovering the work of Józef Maria Bocheński and Jan Łukasiewicz, despite very little of Łukasiewicz's work being translated into English. He went so far as to read untrans...

The physical understanding of acoustical processes advanced rapidly during and after the Scientific Revolution. Mainly Galileo Galilei (1564–1642) but also Marin Mersenne (1588–1648), independently, discovered the complete laws of vibrating strings (completing what Pythagoras and Pythagoreans had started 2000 years ear...

While "local time" could explain the negative aether drift experiments to first order to "v"/"c", it was necessary – due to other unsuccessful aether drift experiments like the Trouton–Noble experiment – to modify the hypothesis to include second-order effects. The mathematical tool for that is the so-called Lorentz tr...

A breakthrough came with work of in the 1970s.

Without making such a conditional assumption on smoothness, he ...

On December 7, 1995, the orbiter arrived in the Jovian system. That day it made a flyby of Europa at 11:09 UTC, and then an flyby of Io at 15:46 UTC, using Io's gravity to reduce its speed, and thereby conserve propellant for use later in the mission. At 19:54 it made its closest approach to Jupiter. The orbiter's elec...
