Round-leafed navel wort, pig’s ear, oblong pig’s ear, narrow pig’s ear, finger pig’s ear, purple pig’s ear; common wild plants have a variety of peculiar names, rooted in a rich history of local lore. View in LinkedIn

MACRO REFLECT MICRO. “Most minerals occur naturally as crystals. Every crystal has an orderly, internal pattern of atoms, with a distinctive way of locking new atoms into that pattern to repeat it again and again. The shape of the resulting crystal -- such as a cube (like salt) or a six-sided form (like a snowflake)-mirrors the internal arrangement of the atoms.” https://www.geologypage.com/2016/03/how-do-crystals-form-grow.html View in LinkedIn

SO ENDS this first of two weekends featuring one aspect of how Nature does large-scale chemistry in aqueous solutions. Biochemists and chemists do these reactions at mg or Kg scales, but geologic processes involve trillions of tons of reactants on the scale of continents. When you survey a landscape remember that it is highly dynamic on geologic time scales. View in LinkedIn

TWO PEAKS. “The nonshifted peak shown in (Figure 1) is due to photon collisions with tightly bound inner electrons in the target material.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

VALIDATION. “Scattering data measured for molybdenum, graphite, calcite, and many other target materials are in accord with this theoretical result.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

QED. “This formula for the Compton shift describes outstandingly well the experimental results.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

LANGUAGE OF MATHS. “The entire physics of Compton scattering is contained in these three preceding equations––the remaining part is algebra.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn

ISOLATED SYSTEM. “This assumption is valid for weakly bound electrons that, to a good approximation, can be treated as free particles.” https://opentextbc.ca/universityphysicsv3openstax/chapter/the-compton-effect/#:~:text=The%20Compton%20effect%20is%20the,wavelength%20of%20the%20incident%20radiation View in LinkedIn
