FCP stories for June 2014

June stories at FCP: (1) If a slice of toast slides off a table, why does it always end up jelly-side down? (2) On a traditional roller coaster, which gives a more frightening ride, the first car or the last car? I do a calculation to get the answer. (3) The church Saint-Sulpice in Paris has an obelisk and a long brass strip to mark a meridian. A spot of light passes over the meridian at solar noon each day, and through the year, the passage point moves along the obelisk or along the strip. (4) In the pub, how can you tell if the eggs on the counter are fresh or hard-boiled?
