I'm the author of "Experimenting With Babies: 50 Amazing Science Projects You Can Perform on Your Kid" (http://www.experimentingwithbabies.com, Oct. 2013)
It has sold more than 100,000 copies, and it even inspired an episode of "The Big Bang Theory," in which Sheldon uses my book to experiment on his friends' kids!
My other three books are:
"Experiments for Newlyweds: 50 Amazing Science Projects You Can Perform With Your Spouse" (https://newlywed.science, April 2019)
"Experimenting With Kids: 50 Amazing Science Projects You Can Perform on Children Ages 2 to 5" (http://www.experimentingwithbabies.com/kids, May 2020)
"Correlated: Surprising Connections Between Seemingly Unrelated Things" (http://www.correlated.org, July 2014)
Aside from writing books, I also write software.
