Sipho: Just know it takes 50,000 drops of liquid tin per second, each individually hit at perfect angle with an exact burst of laser so it is evaporated and in this process, emits extreme ultraviolet light, which is then focused and transported by an intricate pattern of mirrors so that it may be used to etch profiles with edges at 5 nanometer distance.

Wow, very impressive! And all that just to build the world’s smallest better mousetrap!
