Nuclear fission (atom bomb, nuclear power), fusion (hydrogen bomb, Sun) (1940s….) Transistors, semiconductors, superconductors (1940s….) Big Bang theory, cosmic microwave background (1960s…) Quarks, Standard Model of Particle Physics(1960s….) Dark Matter, Dark Energy…..(1990s….) 1900 1920 1940 1960 1980 2000 1910, 18th edition of Ganot. 1928, 1938 Millikan et al. 1949 Sears & Zemansky 1960 Halliday & Resnick (from 1977) 2004 H&R/Cummings 2004 S&Z/Young Milestones from the last century of physics education: Matter can be described in terms of atoms that interact with each other. For those of you who brought your iClicker with you today, let’s do a test run: Turn the Power on. After the question is declared “Open”, choose one: A. My last physics class was in high school. B. My last physics class was in college. C. I have never taken a physics class. D. None of the above. NOTE: From now on, always bring your iClicker to lecture with you. The quizzes count towards your grade. We will use powerful computer graphics to simulate real physical behavior. (Run VPython program for Moon Voyage, which students will write themselves during Lab #3. No prior programming experience needed!) We will show how mechanics plus real atomic behavior leads to thermodynamics: Mechanical forces + quantized atomic energy levels + counting statistics = Thermodynamics/Entropy/Temperature Important Details: Reading Assignment: read Ch 1, sections 1-4 for today, sections 5-11 for Thursday. Go to your assigned Recitation this week. Turn in the first WebAssign HW by Thursday night. Do the first Lab on WebAssign by Tuesday of next week. Register your clicker in CHIP.
