BMW the Author
14er Climber • Rocket Scientist • Published Novelist • Movie Connoisseur • Stock Photographer
Benjamin M. Weilert was born in Colorado in 1985. While he went to school for Mechanical Engineering (eventually earning a Master’s Degree), he has found science to be interesting enough to write fiction about it. He likes to classify his novels as “science fantasy,” wherein the science is real and (semi) accurate, but portrayed in a fantasy setting to make it accessible to non-scientific readers. If you want stories that are surreptitiously educational, he’s your man.

Cool Science
Cool Science is all about making science – actually Science, Technology, Engineering, Art & Math (STEAM) – cool for kids, just like sports, music and  art!  We do this by traveling throughout Colorado, mostly up and down the front range from our base in Colorado Springs, but also to several mountain and western slope communities (and even into Wyoming), bringing our unique blend of cool demonstration shows and hands-on STEAM activities to
elementary and middle schools and libraries year-round.  Best of all, we never turn away any school that can’t pay us.
