Ultrafast lasers produce pulses of light at extremely regular intervals (about 13 nanoseconds apart) that are less than a picosecond in duration. These lasers allow us to study very fast phenomena in crystals and solid nanostructures. The work that my group at Vassar does involves using these lasers to generate and detect ultrasound that is roughly 1,000 times higher in frequency than traditional medical or industrial ultrasound. Since ultrasound can serve as a nondestructive probe of the size or mechanical properties of buried structures, this so called “picosecond ultrasound” should be a great way to study and image the nanoscale structures that form the backbone of all of our modern electronic devices. In this talk, Professor Daly will describe a number of investigations (some very applied, some very fundamental) that we have pursued over the past decade with this optical experiment.
Filmed in 1986/87 in still-divided Berlin, Wim Wenders’ Wings of Desire is both a utopian fairy tale and a fascinating time capsule of that late Cold War moment. Together with legendary French cinematographer Henri Alekan (who had worked on Jean Cocteau’s La Belle et la Bête of 1946, among many other films) and Austrian author Peter Handke (with whom he had collaborated before), Wenders created a multilayered filmic poem of dazzling complexity: the skies over Berlin are populated with angels bearing witness to its inhabitants' everyday concerns. One falls in love with a beautiful young woman, a trapeze artist in a traveling circus, and decides to forfeit his immortality. Wenders’ groundbreaking film has been hailed as a paean to love and a rumination on the continued presence in Berlin of a troubled German history, as well as an homage to the life-affirming power of the cinematic imagination.
Christian Rogowski guides the reader through the film's many aspects, using archival research to bring out new insights into its making and meanings. Rogowski is the G. Armour Craig Professor in Language and Literature in the Department of German at Amherst College.
