/ MAY 10, 2023 Quantum computing has a problem, and it's probably not solvable: reading out the answer. It's proven terrifically difficult getting the answer out of a computation. Quantum computing operates as electromagnetic waves of very low intensit...

/ SEP 28, 2021 I know this is early, but I was just reading Lake Wobegon Day by Garrison Keillor about him as a child going through the Montgomery Ward's Christmas Wish Catalog. I used to do that, but preferred the Sears Christmas Catalog. It was thicke...

/ OCT 25, 2021 I was first licensed as a Technician class back in 1977 with a station call sign1 of WB7WHD. It was a mouthful. I let the license lapse when I was in graduate school because I had other things to do, though I never lost my interest in ra...

/ JUN 06, 2022 I've mentioned here that I have a love for radio. I love tuning around the band to see what's out there. Shortwave is great for that, but it used to be better. A lot of shortwave stations beaming to America shut down because we have so mu...

/ OCT 01, 2021 This is a very long footnote in Garrison Keillor's Lake Webegon Days. It's a set of 95 Theses from a former kid in Lake Wobegon, written after he left the town and found himself. It's titled 95 THESES 95. It was his only copy, and he slid...

The first writers of alchemy seems to have a full blown version of alchemy in mind. This was around 300 A.D. with the Stockholm Papyrus and the Leyden X papyri. Both of these seem to be written by the same author, and are "recipes" of alchemical transformation...

In his 1660 book on experimental science, Robert Boyle made some things clear about how science is to be done: only trust an experiment, never philosophy, never try to make more of your experimental evidence than it directly says, and present your evidence as ...

We don't know the identity of Artephius, but he is very early for European alchemy, right at the forefront, 1160 A.D., when the Arabic alchemy is being translated. His Book of Secrets does not appear to be a retelling of an Arabic alchemical text (though one...
