Kid Scientist is the blog of Jeffrey McManus, a Silicon Valley software engineer and writer, and his daughter, Celeste. When Celeste started kindergarten, they began having a conversation about science every morning — Celeste would ask questions and Jeffrey would answer to the best of his ability. (Sometimes he’d need to look up the answers when they got home.) Their conversations meandered, covering topics ranging from biology, the environment, space, health, you name it. Eventually they decided it would be a good idea to share the subjects of their conversations with the world, so in 2007 the Kid Scientist blog was born.
