Three Lectures by Hans Bethe IN 1999, legendary theoretical physicist Hans Bethe delivered three lectures on quantum theory to his neighbors at the Kendal of Ithaca retirement community (near Cornell University).

Intended for an audience of Professor Bethe's neighbors at Kendal, the lectures hold appeal for experts and non-experts alike. The presentation makes use of limited mathematics while focusing on the personal and historical perspectives of one of the principal architects of quantum theory whose career in physics spans 75 years.

Parallel Park – Parallel parking is a requirement on most standard driver’s license driving tests, yet so many people have no clue how to do it. How could this be?This incomplete list is not intended to be exhaustive. This is a list of current, widely held, erroneous ideas and beliefs about notable topics which have been reported by reliable sources from around the world. Each has been discussed in published literature, as has its topic area and the facts concerning it. In ancient Rome , the architectural feature called a vomitorium was the entranceway through which crowds entered and exited a stadium, not a special room used for purging food during meals.
