... Early on, our interest in chirping analysis functions was motivated by a different kind of chirping phenomenon: chirping due to perspective. ... Our interest in radar, however, drew us toward processes that are more accurately analyzed by linear-FM chirplets. ... We have also constructed other chirplet transforms, such as a three-parameter Doppler chirplet representation that models a source producing a sinusoidal wave, while moving along a straight line (e.g. a train whistle). ...

... Concept Spacecraft . ... The proposed lentiular design concept for the Apollo spacecraft was one of several unorthodox designs rejected in favour of the more familiar conical shape which was lighter and less complex.The lenticular design was a ?road not taken?, losing out to less challenging configurations.It is strange to think that if history had proceeded differently, each Apollo crew could have ended their lunar mission by gliding to a touchdown on a runway at Edwards AFB in a flying saucer! ...

Catastrophism : . ... During the late 18th and early 19th century, a German mineralogist, Abraham Gottlob Werner, proposed that all of the Earth's rocks were formed by rapid chemical precipitation from a "world ocean," which he then summarily disposed of in catastrophic fashion. Though not directed toward the genesis of landforms in any coherent fashion, his catastrophic philosophy of changes of the Earth had two major consequences of geomorphic significance. ...

Next: X--ray Activity and PMS stars . ... This has made the need to study the evolution of the rotation periods of stars, and hence the angular momentum, very clear. ... In the case of low mass pre--main sequence (PMS) stars, we seek to learn whether disks alone determine the angular momentum distribution when stars arrive on the main sequence. ... If one assumes that angular momentum is conserved from the natal cloud, then rotation periods exceeding breakup velocity are implied for PMS stars. ...
