  9. Q1: Feynman’s Question: If in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? The Feynman Lectures on Physics, Vol. 1, Chapter 1, Section 1.2

  10. Feynman’s answer: Matter is made of atoms “In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking is applied.”

  11. Epitaphs of some famous scientists Newton’s Epitaph NATURE and Nature’s Laws lay hid in Night, God said, “Let Newton be!” and all was light. Alexander Pope

  12. Q2: Who has a single mathematical equation as his epitaph? Thermodynamics: Chap 2

  13. Q3: How are atoms arranged inside a solid? Crystallography and structure of solids, Chaps 3 & 5

  14. Q4: Which is the only father-son team to win a Nobel prize? For what? X-ray diffraction, Ch 3

  15. The Kissing number Problem Q5: What is the maximum number of equal sized spheres that can be arranged around a given sphere of same size? Structure of solids, Ch 5

  16. Q6: Why sometimes air simply leaks out of a cycle tube while at other times it comes out with a burst? Chap 12; Fracture

  17. Q7: Why did Titanic sink? Chap 12; Fracture

  18. Q8: Artificial rain?

  19. Q9: Who said (in 1895) “Heavier than air flying machines are impossible” — Lord Kelvin, President of the Royal Society, 1895.

  20. As time permitted I started Lec 2, Ch2 on thermodynamics and covered the first 12 slides upto, S=k ln W.
