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

Getting the shape of an open tin of sardines was an interesting challenge both in shape and in texture. Luckily, sandstone can be highly polished." "" " @marryme.films " "" "#sardines #humor #tin #marine #sealife View in LinkedIn

NO SPACE NO TIME. “A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is so intense that spacetime itself breaks down catastrophically. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when".” https://en.m.wikipedia.org/wiki/Gravitational_singularity View in LinkedIn

OBSERVATION. ‘One peak is located at the wavelength which is the wavelength of the incident beam. The other peak is located at some other wavelength, The two peaks are separated by which depends on the scattering angle of the outgoing beam (in the direction of observation). The separation is called the Compton shift.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

FIGURE 2. “Typical results of these measurements are shown in (Figure), where the x-axis is the wavelength of the scattered X-rays and the y-axis is the intensity of the scattered X-rays, measured for different scattering angles (indicated on the graphs).” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

FIGURE 1. “Experimental data show the Compton effect for X-rays scattering off graphite at various angles: The intensity of the scattered beam has two peaks. One peak appears at the wavelength of the incident radiation and the second peak appears at wavelength.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

PARADIGM SHIFT. “The explanation of the Compton effect gave a convincing argument to the physics community that electromagnetic waves can indeed behave like a stream of photons, which placed the concept of a photon on firm ground.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

THE WAVE. “The Compton effect has a very important place in the history of physics because it shows that electromagnetic radiation cannot be explained as a purely wave phenomenon.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn
