VAST PH RANGES. “The pH of rainwater in any area varies considerably and seems to form a seasonal and regional pattern. The recorded pH values range from 3.0 to 9.8.” https://lnkd.in/ete8CApd View in LinkedIn

IONIC BREW. “The stability of soil clay minerals is influenced by the constant accession of cations from rainwater. Conversely, the clay minerals modify the amounts and kinds of cations that are leached out by drainage waters. The stability of micaceous minerals in soils may be partly due to accessions of K+1 ions from rainwater.” https://lnkd.in/ete8CApd View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the topic of the constant flux of rocks. Geology is about constant transformations and highly dynamic processes occurring at large time and space scales with an enormous variety of components, resulting in a staggering diversity of rocks. https://lnkd.in/ete8CApd View in LinkedIn

NEMATODES, or roundworms, are among the most abundant animals on the planet. But when researchers looked at a variety of nematodes, they found the very same types of chemicals being combined and used for communication, says Paul Sternberg, professor of biology. “It really does look like we’ve stumbled upon the letters or words of a universal nematode language, the syntax of which we don’t yet fully understand.” https://lnkd.in/eUkRKpG5.

RARITY. “Seldom, an electron will escape by absorbing two or more quanta. Still, this is extremely rare because by the time it absorbs enough quanta to escape, the electron will probably have emitted the rest of the quanta.” https://lnkd.in/eDZvjevE View in LinkedIn

NOBEL LAUREATE. “As a child I was always interested in building things. Instead of buying candy, I would purchase nails which I used to construct things out of scrap wood. My mother always claimed that my spending my money on nails instead of on candy was why I was so skinny as a kid.” (Robert H. Grubbs). https://lnkd.in/e9-viyDe View in LinkedIn

ODDITY. “Below that threshold, no electrons are emitted from the material irrespective of the light intensity or the length of time of exposure to the light.” https://lnkd.in/eDZvjevE View in LinkedIn

“SULFATE ions in rainwater come from several sources. In industrial areas the principal source is the combustion of fuels containing sulfur. In other areas sulfate comes from shallow-water marine environments.” https://lnkd.in/ete8CApd View in LinkedIn
