In his seminal 1959 lecture “There’s Plenty of Room at the Bottom” Richard Feynman has put forward two challenges [1] .The first was to shrink letters to a size, which allowed writing the whole Encyclopedia Britannica on the head of a pin - which was achieved in 1985 [2].The second challenge read: “It is my intention to offer a prize of $1,000 to the first guy who makes a rotating electric motor which can be controlled from the outside and, not counting the lead-in wires, is only 1/64th inch cubed” [1].
