Can you use a magnifying glass and moonlight to light a fire? (2016)
A magnifying glass concentrates light on a small spot. As many mischevious kids can tell you, a magnifying glass as small as a square inch in size can collect enough light to start a fire. A little Googling will tell you that the Sun is 400,000 times brighter than the Moon, so all we need is a 400,000-square-inch…

Eldar Black Holes
Isaac Asimov, in one of the anthologies he edited, mentioned reading some astronomical news back in the early 1960s about neutron stars. Being a science popularizer as well as a science fiction author, he was inspired to write a science essay about neutron stars. This was read by a few people but then more or less…

How to Be a Systems Thinker
At the moment, I’m asking myself how people think about complex wholes like the ecology of the planet, or the climate, or large populations of human beings that have evolved for many years in separate locations and are now re-integrating. To think about these things, I find that you need something like systems theory…

Wendelstein 7-X achieves world record
In the past experimentation round Wendelstein 7-X achieved higher temperatures and densities of the plasma, longer pulses and the stellarator world record for the fusion product. Moreover, first confirmation for the optimisation concept on which Wendelstein 7-X is based, was obtained. Wendelstein 7-X at Max Planck…
