“Mary, what’s come over you?” Susan’s mother was finishing up a spreadsheet when I led Susan’s father into the control room. She didn’t notice him at first, then jumped up as soon as he approached her desk. He took her hand but stood staring at the computer screen. “We don’t know anything about the Earth’s internet,” he said. Susan came to her mother’s rescue: “Papa, we’re living in a different time now. The internet helps us all lead better lives.” He frowned. “Maybe you,” he said. “But not us. C’mon, Mary, let’s go.” I asked Deadpan how astronauts got into space. He says they stood on the shoulders of giants.
