All aboard as I attempt to simulate the artistic process of paper marbling. The algorithm is based on the paper 'Mathematical Marbling' by S. Lu, A. Jaffer, ...

TIL that there is a species of fish (common name : bogue) with the scientific name Boops Boops. Sadly, it's pronounced bow-ops.

Ferrocell, an awesome magnetic field viewer, magnetic field perception is undoubtedly better than any other system. It's easy to make, but be careful, ferrof...

The Wikipedia page on the Hall effect says: I probably don't have the math ability or the time to master solid state physics in all its glory, but I am hoping to get to a heuristic picture of the P-type Hall effect that, at the very least, won't be "not even wrong". My attempt is as follows...

Henry A. Rowland is known for his pioneering work on the manufacture of high quality diffraction gratings. A less known experiment of his is the demonstration that a mechanically rotating charged disk produces a magnetic field, equivalent to that of a current in a similarly shaped flat coil...

Edwin Hall on his discovery of the Hall Effect: https://web.archive.org/web/20070208040346/http://www.stenomuseet.dk/skoletj/elmag/kilde9.html Although published as a scientific paper, it reads in part like a personal narrative... It would be fun if papers were written in that style today. Or...

From "Boffin : a personal story of the early days of radar, radio astronomy, and quantum optics", by R Hanbury Brown... If it had been truly coherent (e.g. laser light), wouldn't the detection events have been uncorrelated? That is, two independent Poisson processes?
