Trained in mathematics, physics, cosmology, computer programming and science journalism. Retired mathematician, award-winning technical and journalistic writer. 1989 winner of the Bruce B. Howat Award-- an international business-journalism equivalent of the Pulitzer Prize. (Only one Howat was awarded each year, IF the committee in Geneva found an article they really liked. But I don't think the prize is granted anymore.) Also a past author and editorial advisor for Sesame Street... where I regularly worked with Jim Henson and Kermit!
