Overview of our Planetary System (7.1);
 * How bright is the Sun compared with other stars?
 * What fraction of the Solar system consists of the Sun?
 * What fraction of all the planets, asteroids, and moons consists of Jupiter?
 * What are trans-Neptunian objects?
 * Roughly how many trans-Neptunian objects have been identified?

Composition and Structure of Planets (7.2);
 * Differentiation

 * Test hint: Formation of the Solar System: Gravity recovers debris from collisions in a fashion that creates low-density structures that resemble dust bunnies. Accretion is the name for the process by which gravity enhances the growth of protoplanets.

W 2/7/18 Mercury
Finish Ch9 with Mercury. A volatile subsance melts or evaporates at low temperature. Hydrogen and helium are most volitile, followed by water, followed by silicates (sand/glass), followed by the metals as the least volatile. Since it is so close to the sun, Mercury has has few volatile substances. Start

Attempt to log into Miraheze. Also, poll students on whether they have WMF (Wikipedia/Wikiversity) accounts.
 * Test hints:
 * 1) The life cycle of stars like the sun: Protoplanetary disk-yellow dwarf-red giant-white dwarf.  Discuss red giant stage in light of temperature and light energy production. See w:special:permalink/823036569 and File:Sun_red_giant.svg
 * 2) The protoplanetary disks might have resembled the ring systems of our gas planets. See w:special:permalink/823862648 and note the dubious nature of the most recent edit.

 * Write the lede for Physics_and_Astronomy_Labs/Radioactive_decay_with_dice. You may either write by hand hand to me personally, or you may write electronically and submit a pdf to pilot.  Best is to write on Miraheze and submit a permalink.
 * If you submit by hand: Place name and date on upper inch margin. Write "Public Domain CC0" somewhere below that margin.
 * If you submit a word or pdf file via Pilot. License it with "Public Domain CC0"

T 2/20/18 The failure of the shephards
[https://highered.mheducation.com/olcweb/cgi/pluginpop.cgi?it=swf::800::600::/sites/dl/free/0072482621/78780/Solar_Nav.swf::Solar%20System%20Builder We were unable to get this simulation to exhibit sheparding. Instead two Hot Jupiters bookending 8-12 "plutos" eventually ate all of them. This shows the giant planet "cleaning" out it's region, but not the "pushing" of satellites away from the planet's orbit.

This video shows the actual sheparding of a small ring around Saturn

W 3/14/18 Bell's theorem card game

 * Not popular with the class, but why?
 * Two interesting quotes:
 * Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from "indifference" to "wild extravagance".
 * Lawrence Berkeley particle physicist Henry Stapp declared: "Bell's theorem is the most profound discovery of science."


 * I couldn't sleep for 3 days when I realized what was going on back in the 1990s
 * Any interest in understanding Einstein's special theory of relativity and how we know information cannot travel faster than the speed of light?

Conclusion: Today we reviewed relative velocity using the "man-on-train" at Relative velocity. Then we did the clock argument at wikipedia:special:permalink/829634204. We reviewed the card game and a solid majority voted to play the couple's game at least once.

Next time, lets look at this:
