關於本有聲書
Roger Bacon can be placed on the boundary between magic and science. This essay starts with a strong dissenting opinion on the existence of magic; but finishes by discussing how to create a 'Philosophers Egg'. In between, Bacon writes about the use of optics, gunpowder, and petroleum in warfare.
