Adox HR-50 is not the most tolerant film. With at least 5 stops between the two halves (and leaving A1 in auto mode๐Ÿ˜ฎ) I was not expecting too much.
But St. Silverfast is able to see something that you can amplify. Dodging and burning in DR could be a nice pastime, too๐Ÿ˜

Alchemy: A Curated Story of Transmutation This article offers a detailed review of Philip Ballโ€™s recent book on alchemy. It situates and interprets the work within contemporary debates regarding the science-pseudoscience distinction, the h...

A wonderfully in-depth review and critique of my book Alchemy.

"Philip Ballโ€™s Alchemy is an erudite and sumptuous work that aims to place alchemy as one of the great intellectual adventures in the history of ideas."

The quest to understand where atoms end Atomic size measurements like van der Waals and covalent radii are central to chemistry, but are they grounded in reality?

Where is the edge of an atom? My article for @chemistryworld.com on efforts to figure out the size of atoms, and why it matters.

>> tuttavia, se hai tante cose ancora da raccontare, ci vuole chi le vuole ascoltare, se no va a ramengo tutto il resto.

(e l'incapacitร  di ascoltare un discorso che abbia una completezza sintattica sta diventando sempre piรน un problema, si peggiora letteralmente e visibilmente anno dopo anno).

"non esistono leggi in amore" รจ sempre un buon principio. Credo che una lezione frontale in cui si indica dove e perchรจ andare a cercare /rivedere argomenti di approfondimento possa essere un buon compromesso. >>

Hungary's leader orders extra security at energy sites, claiming Ukraine plots disruptions Hungarian Prime Minister Viktor Orbรกn ordered extra security at critical energy infrastructure sites after claiming Ukraine was attempting to disrupt Hungaryโ€™s energy system.

Viktor Orban is now 20 points behind in the polls - and so he has ordered the military to guard โ€œkey energy facilitiesโ€ against a possible Ukrainian โ€œattack.โ€ Hungarians fear he plans a fake national security emergency or false-flag incident before the April 12 election
