Early electronics: a cell for isolating minute quantities of heavy metals, apparently by zapping a drop of a solution under a powerful microscope and seeing what’s left behind. (Though this looks more like a mechanism for getting droplets of heavy metals to rise into a pipette by heating and cooling the water underneath and getting the warmed solution to touch a copper wire inside the glass capillary – the slender tube coming off at an angle. Just a guess.)

Yes, this song is two days late, so I shall be covering a cover, probably horribly, sometime soon.

I had music sort of set up for this (more or less) a week ago, then coul…

Science Art: The midnight sun, from Atlas zu Alex. V. Humboldt’s Kosmos, 1851.

Polar bears salute the midnight sun as Arctic explorers sail to the horizon.

This image is part of a page of “Cosmic Meteorological Landscapes” that are all pretty fantastic.

Traugott Bromme made this atlas with (or as a supplement to) Alexander von Humboldt. Both were great wanderers – Bromme was from Leipzig, but in the mid-19th century wrote one of the first guidebooks to the United States, Canada, and Central America for Europeans (a favorite text for German immi…

Science Art: What is that green gunk?, USGS/NASA, 2 Nov 2017

The answer, from the US Geological Survey’s Facebook page, is an algal bloom in Lake Erie, as photographed by Landsat:

In late September, Earth-observing satellites documented a large algal bloom in Lake Erie, which coated much of the water with a bright green skin-like slime. This goo, called cyanobacteria, is made up of microorganisms similar to algae and bacteria. When excess nutrients build up in the lake, cyanobacteria multiply rapidly, creating harmful algal bloo…
