Two books that are interesting to read together. Illich's book could be called an essayistic cultural history of water and he wrote it in 1984, heavily inspired by Bachelard's book from 1942, which had then just been translated into English. Now is the moment for somebody to write a sequel and keep the 42-year cycle going.

Tomorrow, Friday the 29th of May, at 17h there will be a special screening of my film "Mechanisms Common to Disparate Phenomena; #59" in Ghent at the IPEM Art and Science Interaction Lab of the UGent.
After that there will be a short Q&A and an informal book presentation.

So today I was getting all excited by this dusty tome from 1910/1923, a recent arrival after it was cited in the fantastic book by Bernadette Bensaude-Vincent that I finally finished reading.

Finally finished building, testing and calibrating (sort of) this 1 KV power supply; first display is in Volts, the second in mA. Things are slowly coming together...

There is a very interesting French lineage of philosophers and historians of science engaging with chemistry and these early writings by Pierre Duhem were also early contributions to that lineage; a very interesting book on the evolution of chemical concepts of mixedness and combination from 1902 and a great and nuanced history of the precursors of Lavoisier, published during WWI.

With my crude metal-working skills and capabilities I built this strange contraption of steel and mica, hoping it will be fit for purpose and able to resist high voltage and high temperature.

One of those periods were the reading pile grows a lot faster than it shrinks: I have only recently become aware of Feenberg's existence and this book from 2017 I think is his most recent. It looks very interesting indeed.

Spent way too much time trying to get this horizontal amplifier not to be biased and failing miserably. All components seem to be fine but the whole is not. Argh.

The Tektronix 7704A oscilloscope is the most modular analogue oscilloscope I know: not only does it have space for four amplifier and trigger plugins, but even the 'display unit' holding the CRT can be swapped for another one.
After several years of owning a spare 'display unit' I finally have a project where this strange feature may turn out to be actually useful. But first these machines need some maintenance and repair.
