Clearly a pigment of our imagination.
Do these count? Perhaps a generous definition of “wind” to include convection:

What happened to all the ancient Egyptian mass spectrometers then?
I understand the confusion, but Egyptians didn’t have devices to weigh charged particles. Instead they would weigh people’s hearts against the feather of truth to determine whether they were worthy of entering paradise. So, you know, it’s more of a Ma’at spectrometer.
Thanks for the earworm!
Are you referring to
Cahill, T. A., Schwab, R. N., Kusko, B. H., Eldred, R. A., Moller, G., Dutschke, D., … Pooley, A. S. (1987). The Vinland map, revisited: new compositional evidence on its inks and parchment. Analytical Chemistry, 59(6), 829–833. doi:10.1021/ac00133a009
That abstract reads
The Vlnland Map, once considered the first cartographic evidence of the North American continent, purportedly dates from the mid-15th century. In 1974 compositional evidence derived from microparticles removed from Its surface led McCrone Associates to conclude that Ink In the Map was made up of 20th century titanium-based pigments containing up to 50% anatase (TIO2) and that the Map was therefore a forgery. Recently at Davis, 159 multi elemental PIXE (particle Induced X-ray emulsion) analyses of the Vinland Map were performed, Including spatial analyses of the parchment, 33 closely matched Ink-parchment pairs, and transects across Inked lines with 0.5 mm resolution. The results show that titanium and other medium and heavy elements are present In only trace amounts In the Inks, with titanium reaching a maximum value of 10 ng/cm2, or about 0.0062% by weight. In the light of these results the prior interpretation that the Map has been shown to be a 20th-century forgery must be reevaluated.
Allegedly the same method as this most recent study, yet it comes to the opposite conclusion.
Also because the people who’s identities are invested in them tend not to allow them to be tested. The Shroud Of Turin is a good example. It was shown to be a hoax hundreds of years ago, yet people still cling to it and cite it as evidence for religious beliefs.
This makes Planck’s principle sound optimistic by comparison.
Planck sounds like a spring chicken who was too young to have ever opposed statistical thermodynamics.
I like the cut of your Gibbs!
That is the best possible reply.
