Trained in mathematics, physics, computer programming and science journalism. Retired mathematician, award-winning technical and journalistic writer. Past winner of an international business-journalism equivalent of the Pulitzer Prize. And past author and editorial advisor for Sesame Street... where I regularly worked with Jim Henson and Kermit! Now enjoying "retirement studies" of photography, quantum physics and "scientific spirituality." (And restoring a shamefully lapsed relationship with the piano.)
