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

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

IONIC SOURCES. “In humid regions the important amounts of calcium, magnesium, sodium, and potassium added yearly by rain may be expected to influence the composition of the soil water and thereby the cations in the exchange positions of soil clay minerals. The acquisition of cations by clay minerals may slow down chemical weathering.” https://lnkd.in/ete8CApd View in LinkedIn
