This collection has 14 essays. They cover pregnancy and health, number bases and applications, statesmanship, theology and Christ, submarine design, a new type of engine, a general discussion of the basics of space, time and matter with respect to physics, a way to endure high g forces in flight, monetary policy and economics, and pest control. That was a long sentence that you just read, but my essays tend towards the succinct and simple (relatively speaking.) Thanks for noting my book, and I hope you enjoy it if you read it.
