Indicator Quotes (6 quotes)

Acid Salts have the Power of Destroying the Blewness of the Infusion of our Wood [lignum nephreticum], and those Liquors indiscriminatly that abound with Sulphurous Salts, (under which I comprehend the Urinous and Volatile Salts of Animal Substances, and the Alcalisate or fixed Salts that are made by Incineration) have the virtue of Restoring it.
Experiments and Considerations Touching Colours (1664), 212.

One indicator of Ernest Lawrence’s influence is the fact that I am the eighth member of his laboratory staff to receive the highest award that can come to a scientist—the Nobel Prize.

Penguins are an indicator of the health of our watery planet, and if they are unable to survive, we had better take notice or we might find our own survival threatened.

Taxonomy is often regarded as the dullest of subjects, fit only for mindless ordering and sometimes denigrated within science as mere “stamp collecting” (a designation that this former philatelist deeply resents). If systems of classification were neutral hat racks for hanging the facts of the world, this disdain might be justified. But classifications both reflect and direct our thinking. The way we order represents the way we think. Historical changes in classification are the fossilized indicators of conceptual revolutions.
In Hen’s Teeth and Horse’s Toes: Further Reflections in Natural History (1983, 2010), 72

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
