Final Flashcards
Paradigm
Unprecedented and openended set of assumptions that direct nsci. Forces choice, defeats competition, and leaves puzzles.
Barr on BBang as anomaly
Dates for evidence
Steady state theory (bondi, gold, Hoyle)
Bouncing, baby, inflation theory
Friedman/Lemaitre
1924 guessed beginning using relativity
Slipher
1925 receding galaxies
Hubble Humeson
Hubble’s law and increase in speed 1929
Alpher Herman
1948 predicted radiation from BBang
Penzias and Wilson
1965 radiation
Continental drift as anomaly
Overcame old p with evidence (dates)
Wegener
Theorized continental drift but mechanism disproved
Hess Dietz
Sea floor spreading with Fathometer and other new tech
Vine Matthews
Paleomagnetism on mid ocean ridges and drill cores
Anomaly
Counterinstance to nsci. Often, unless anomaly creates crisis, scitists don’t abandon p
