Notes. 1. "There is no human experience that can be termed true science unless it can be mathematically demonstrated. And if thou sayest that the sciences which begin and end in the mind are true, this cannot be conceded, but must be denied for many reasons, and firstly because in such mental discourses experience is eliminated, and without experience there can be no certainty.” —Leonardo Da Vinci, Thoughts on Art and Life 2. "I should even think that in making the celestial material alterable, I contradict the doctrine of Aristotle much less than do those people who still want to keep the sky inalterable; for I am sure that he never took its inalterability to be as certain as the fact that all human reasoning must be placed second to direct experience." --From the Second Letter of Galileo Galilei to Mark Welser on Sunspots, p. 118 of Discoveries and Opinions of Galileo, translated by Stillman Drake, (c) 1957 by Stillman Drake, published by Doubleday Anchor Books, Doubleday & Co., Garden City, New York 3. “To reject all anecdotes is also to reject facts.“ --Bernd Heinrich, the Mind of the Raven 4. "Biology is a sterile undertaking, until one gets hands-on experience." ---Bernd Heinrich, in his book Winter World 5. Anecdote definition from https://www.dictionary.com/browse/anecdote i. "a short account of a particular incident or event, especially of an interesting or amusing nature." ii. "a short, obscure historical or biographical account." 6. Anecdote definiton from https://www.merriam-webster.com/dictionary/anecdote "a usually short narrative of an interesting, amusing, or biographical incident" They also say: "The Byzantine official Procopius wrote three historical works in Greek. In the first two, he dealt with wars and public works projects, but the third was something of a departure from this kind of history. Referred to as 'Anekdota,' from the Greek a- meaning 'not,' and ekdidonai, meaning 'to publish,' it contained bitter attacks on the emperor Justinian, his wife, and other notables of contemporary Constantinople. Understandably, it was not published until after its writer's death. English speakers originally used an anglicized version of the book's name for similar secret or unpublished histories or biographies, and by the 17th century, the meaning of anecdote had been broadened to cover any interesting or amusing personal tale." 7. Anecdote etymology from https://www.etymonline.com/word/anecdote "1670s, 'secret or private stories,' from French anecdote (17c.) or directly from Medieval Latin anecdota, from Greek anekdota 'things unpublished,' neuter plural of anekdotos, from an- 'not' (see an- (1)) + ekdotos 'published,' from ek- 'out' (see ex-) + didonai 'to give' (from PIE root *do- 'to give'). Procopius' 6c. Anecdota, unpublished memoirs of Emperor Justinian full of court gossip, gave the word a sense of 'revelation of secrets,' which decayed in English to 'brief, amusing story' (1761)." 9. Science definition from https://www.dictionary.com/browse/science "a branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws;" or "systematic knowledge of the physical or material world gained through observation and experimentation;" or "systematized knowledge in general." 9. Science etymology https://www.etymonline.com/search?q=science "mid-14c., 'state or fact of knowing; what is known, knowledge (of something) acquired by study; information;' also 'assurance of knowledge, certitude, certainty,' from Old French science 'knowledge, learning, application; corpus of human knowledge' (12c.), from Latin scientia 'knowledge, a knowing; expertness,' from sciens (genitive scientis) 'intelligent, skilled,' present participle of scire 'to know.' "The original notion in the Latin verb probably is 'to separate one thing from another, to distinguish,' or else 'to incise.' This is related to scindere 'to cut, divide' (from PIE root *skei- "to cut, split;" source also of Greek skhizein 'to split, rend, cleave,' Gothic skaidan, Old English sceadan 'to divide, separate'). "OED writes that the oldest English sense of the word now is restricted to theology and philosophy. From late 14c. in English as 'book-learning,' also 'a particular branch of knowledge or of learning, systematized knowledge regarding a particular group of objects;' also 'skillfulness, cleverness; craftiness.' From c. 1400 as 'experiential knowledge;' also 'a skill resulting from training, handicraft; a trade.' "From late 14c. in the more specific sense of 'collective human knowledge,' especially that gained by systematic observation, experiment, and reasoning. The modern (restricted) sense of 'body of regular or methodical observations or propositions concerning a particular subject or speculation' is attested by 1725; in 17c.-18c. this commonly was philosophy."
