LIGHT + MATTER. “In 1905, Albert Einstein (14 March 1879–18 April 1955, Nobel Prize in Physics 1921) published a paper advancing the hypothesis that light energy is carried in discrete quantized packets (photons), each with energy hν to explain experimental data from the photoelectric effect.” https://lnkd.in/eDZvjevE View in LinkedIn

QUANTA CONCEPT. “In 1900, while studying black-body radiation, the German physicist Max Planck (23 April 1858–4 October 1947, Nobel Prize in Physics 1918) (Figure 2) suggested that the energy carried by electromagnetic waves could only be released in “packets” of energy.” https://lnkd.in/eDZvjevE View in LinkedIn

CATION EXCHANGES. “The cations of the soluble salts in saline soils occupy the exchange positions of the clay minerals and modify or prevent development of soil profiles, particularly with regard to the movement of clay. Sodium in exchange positions may cause a flocculated, jellylike mass of clay similar to a sodium bentonite when wet.” https://lnkd.in/ete8CApd View in LinkedIn

ORBITAL SHELLS. “In 1925 H. Robinson, a pioneer who dedicated his entire scientific career to XPS, wrote that, “…an accurate knowledge of the energies associated with the different electronic orbits within the atoms is essential to the further development of the theory of atomic structure.” (XPS = X-ray photoelectron spectroscopy). https://lnkd.in/eDZvjevE View in LinkedIn
