QUANTUM VS CLASSICAL. “From the point of view of Newtonian classical mechanics, these two characteristics imply that a photon should not exist at all.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

SPECIAL PHOTONS. “Unlike a particle of matter that is characterized by its rest mass a photon is massless. In a vacuum, unlike a particle of matter that may vary its speed but cannot reach the speed of light, a photon travels at only one speed, which is exactly the speed of light.“ https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

LIGHT + MATTER. “A beam of monochromatic light of wavelength (or equivalently, of frequency f) can be seen either as a classical wave or as a collection of photons that travel in a vacuum with one speed, c (the speed of light), and all carrying the same energy, This idea proved useful for explaining the interactions of light with particles of matter.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

THE COMPTON EFFECT. “Two of Einstein’s influential ideas introduced in 1905 were the theory of special relativity and the concept of a light quantum, which we now call a photon. Beyond 1905, Einstein went further to suggest that freely propagating electromagnetic waves consisted of photons that are particles of light in the same sense that electrons or other massive particles are particles of matter.” https://lnkd.in/gsP2UEqH.

METASOMATISM. “I would like you to look at it from a far broader viewpoint—as a universal process based on the fact that the minerals of all rocks are soluble in the fluids of nature, particularly water, but also in the mixed emanations from magmas, and on the fact that these fluids change the minerals to others, of different composition, stable under the particular conditions of pressure and temperature prevailing. Remove metasomatism and there would be very little left of metamorphism.” https://lnkd.in/enQ7UEgW View in LinkedIn

THE NARROW VIEW. “Perhaps I am right in saying that there is a general impression abroad that metasomatism is a sort of replacement of one mineral by another, with addition of material and mainly of importance in ore deposits.” (1925). https://lnkd.in/enQ7UEgW View in LinkedIn

BULK AQUEOUS CHEMISTRY. “Metasomatism is the drastic change in the bulk chemical composition of a rock, due to the introduction of chemicals from other surrounding rocks.” https://lnkd.in/eSpeQsqS View in LinkedIn

FRAGMENT FROM NATURE features a 1925 article by the prolific Waldemar Lindgren on metasomatism in geology. He “began a 31-year career with the U.S. Geological Survey, and then he was appointed head of the Department of Geology at the Massachusetts Institute of Technology. Also featured is an excellent article by a rare woman geologist, Dorothy Carroll, on aqueous processes in geology, at the heart of metasomatic processes. https://lnkd.in/ei_gnmMD View in LinkedIn
