I'm a kind, compassionate, retired scientist, deeply curious about the universe and the human brain, with computer programming and organ playing as lifelong passions. Also very interested in NASA space missions, robotics, internet-of-things, artificial intelligence, and physical computing education. Hobbies including creating apps, listening to cathedral music, playing tennis, reading beautiful poems, and building cool websites. I am very curious about the nature of dark energy and dark matter in the universe, whether there is any form of life outside planet earth, and the brain's "software"
