1. astronomy
I. definition
i. astronomy loosely translated means “patterns among the stars” (mc: 1)
II. your place in the universe
i. your address: street, city, town, country, earth, sun, milky way, local group, virgo
supercluster, universe (mc: 3, sa: 1)
ii. solar system: classical versus dwarf planets (tf: 1, 2, mc: 1–4, 7, sa: 2)
iii. milky way: contains 200 to 400 billion stars (mc: 3, 5–7)
iv. local group (mc: 3, 8)
v. virgo supercluster (tf: 3, mc: 3)
vi. universe: contains hundreds of billions of galaxies, roughly as many stars as in
the milky way (tf: 4)
vii. much of the universe is made of dark matter, and all of space is permeated by
dark energy (tf: 5, mc: 9, 10)
III. scale of the universe
i. speed of light, c 3 108 m/s (mc: 11)
ii. d v t (tf: 2, mc: 12–17)
iii. light year is a measure of distance (tf: 6, mc: 12, sa: 3)
iv. distance versus time comparison: circumference of the earth versus
snapping your fingers (mc: 19, 20, sa: 4–6)
, IV. origin and evolution of universe
i. age of universe: 13.7 billion years (mc: 21)
ii. big bang created the initial chemical elements: h, he, li, be, b (tf: 7, mc: 22, 23)
iii. stars manufactured the other chemical elements from nuclear burning and
explosions (tf: 7, 8, mc: 24, 25, sa: 7)
iv. solar system formed
v. life evolved on earth
sec 1.2
2. science involves exploration and discovery
I. evolution of astronomy from new technology
i. satellites, e.g., sputnik, lunar exploration, solar system exploration (tf: 10, mc:
26, sa: 8, 9)
ii. space-based astronomy used for high spatial resolution and access to
wavelengths blocked by the atmosphere (tf: 10, mc: 27, sa: 9, 10)
iii. cross disciplines: astronomy, physics, chemistry, geology, planetary science
iv. computers: a new important tool for astronomers (sa: 9)
sec 1.3
3. science is a way of viewing the world
I. scientific method
i. scientific method (mc: 28, 29, sa: 11)
ii. rational inquiry
iii. facts
iv. hypothesis (mc: 28, 30, sa: 11)
v. theory (mc: 28, 30, sa: 12)
vi. testable predictions/falsifiable (tf: 10, 11, mc: 28, sa: 11)
vii. physical laws
