Off the top of my head, I believe George Gamov wrote a book decades ago entitled, "One, Two, Three - Infinity" which explained the basics of nuclear weaponry sufficiently for a writer to create a feasible scenario or description. He also explains things like how to do a simple home experiment to calculate how large a molecule of water is.
Genius is simple. When asked to define time and space, Einstein replied, "Time is measured with a clock and space is measured with a ruler."
