“Volcanic ash, despite the name, is dense as rock and can cause significant damage to structures, power lines and communications. It is also toxic because it contains chemicals such as sulfur, chlorine or fluorine, and it can therefore affect water supplies.”

“Psychiatrists look for twisted molecules and defective genes as the causes of schizophrenia, because schizophrenia is the name of a disease. If Christianity or Communism were called diseases, would they then look for the chemical and genetic “causes” of these “conditions?””

“It is important for human beings and animals to drink healthy water. Chemically purified water, chlorinated or ozonated water is no longer living and healthy water. Good water, full of life and rich in energy, is synonymous with strong and healthy life. Bad water is synonymous with sick life. No water is the same as no life.”

“Saying that a smoker inhales over 4000 chemicals is as meaningful as saying that fun runners pass over 4000 different kinds of rock, and because that rock may contain dinosaur fossils, said fun runners are at risk of velociraptor attack.”

“A dense film of a conventional surfactant is quite impermeable. On the other hand, a dense film of Janus grains always has some interstices between the grains, and allows for chemical exchange between the two sides; "the skin can breathe."”

“The real significance of the Russell paradox, from the standpoint of the modal-logic picture, is this: it shows that no concrete structure can be a standard model for the naive conception of the totality of all sets; for any concrete structure has a possible extension that contains more 'sets.'”

Hilary Putnam (1926–2016) American philosopher

Context: (If we identify sets with the points that represent them in the various possible concrete structures, we might say: it is not possible for all possible sets to exist in any one world!) Yet set theory does not become impossible. Rather, set theory becomes the study of what must hold in, e.g. any standard model for Zermelo set theory.

“When (volcanic) ash falls into the ocean, it brings with it nutrients. For example, It can bring iron, which is usually quite low in the ocean. It can suddenly create a bloom of plankton, which then go through the food chain, creating a population boom later on the fish and other lives too.”
