Seems that this particular kind of teenage bug has evolved bio-gears to help it jump, giving it an acceleration of a whopping 400 g! Pictures are from the website above.  The adults are more responsible, of course.

A Visual Catalog of Physics and Astronomy Building Stone Carvings

door_archway_carvings_550-0001Our history web pages have a wonderful new addition.

Professor Emeritus  and photographer Donald R. Moorcroft has compiled a complete visual catalog of all of the stone carvings and sculptures which make up the exterior of the Physics and Astronomy Building.

This catalog of stone carvings is now part of our history web pages, which you may notice are now in a new location outside of the news folder structure of the departmental web pages. However they are still linked through the News area.
