6 Atomic talk They’re what is you

7 Why it matters When a journalist asked the great physicist Richard Feynman what single sentence would best encapsulate all science so far if it were to be the sole surviving scrap of all we knew, he replied, “The world is made of atoms. ” From The Secret of Scent, Luca Turin p. 28

Atoms: the stuff of life ❖ DNA, RNA: C, H, N, O, P, [Mg++] ❖ Carbs: C, H, O ❖ Protein: C, H, N, O, (S), (P) ❖ Membranes: C, H, N, O, P, (S) That’s pretty much it. Understand these and how they combine/interact and you’re almost done. *OK, fine, there’s the occasional role for Ca++, etc. 8

9 Color your world: representing atoms Study hint: Memorize the first 4. Now.

Atoms together ❖ DNA? molecule ❖ Sugar? molecule ❖ Lipid? molecule ❖ Protein? molecule ❖ Enzyme? molecule made of protein ❖ nucleotide? molecule ❖ amino acid? molecule ❖ You? complicated machine made of interacting… molecules 10

12 Adding to your tree of knowledge Knowledge, assumptions, hearsay

Faith v. Science 13

Rank these 'ways of knowing' A) Your roommate calls & says your stove is on B) I tell you that the stove in your apartment is on C) Campus safety calls & says your stove is on D) You touch the stove & burn your finger

Example: knowing 15 ❖ The sun is way far away*--its rays are essentially parallel ❖ In Syene, the sun is directly overhead at noon ❖ In Alexandria, at noon**, a large vertical*** column’s shadow marks out a 7. 2˚ angle ❖ Q. E. D. http: //www. wired. com/science/discoveries/news/2008/06/dayintech_0619

Framework: a ranked list 16 i) Empirical: you see it, touch it, etc. ii) Reasoned argument: derived from #1 and/or documented/identified assumptions. ❖ --Sound conclusions survive the ‘sniff test’ iii) Repeatedly established by others that you ‘trust’ (scientific literature goes here on a good day) v) Not allowed: assertion from authority solely on the basis of that authority, regardless of the nature (or volume) of that authority. NEVER! Death before dishonor!

Wintu ❖ tenses dedicated to. . . hearsay! ❖ http: //en. wikipedia. org/wiki/Wintu_language ❖ "position inflectional suffixes: 1. non visual sensory evidential, 2. hearsay evidential, 3. inferential evidential 4. experiential evidential 5. subordinating causal anteriority 6. approximation" 17
