摘要

1959年,理查德·费曼在他开创性的演讲《底部有足够的空间》中提出了两个挑战[1]。第一个挑战是将字母缩小到一定的尺寸,这样就可以在大头针的针尖上书写整部《大英百科全书》——这在1985年实现了[2]。第二个挑战是:“我打算向第一个制造出可以从外部控制的旋转电动机的人提供1000美元的奖金,这个电动机不包括引入线,只有1/64英寸的立方”[1]。

When a molecular motor does the quantum leap
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].

期刊介绍: Europhysics News is the magazine of the European physics community. It is owned by the European Physical Society and produced in cooperation with EDP Sciences. It is distributed to all our Individual Members and many institutional subscribers. Most European national societies receive EPN for further distribution. The total circulation is currently about 25000 copies per issue. It aims to provide physicists at all levels, ranging from post graduate students to senior managers working in both industry and the public sector, with a balanced overview of the scientific and organizational aspects of physics and related disciplines at a European level. Sections covered: ◦Activities ◦Features ◦News and views
