自行车的稳定性看起来并不复什,但要掌握其运动的原理,却令人捉摸不透。其中很多问题,物理学家和力学家还不能明确地阐明。北伊利诺斯大学有位工程教授Jim Papad opoulos,在研究这个问题时发现,在历史上,企图解释自行车稳定性的科学家们,已提出了25个方程,其中3个是正确的,2个接近正确,20个为离脱实际的设想。然而竟无1人对自行车 The stability of a bicycle does not seem to be a concern, but it is unpredictable to grasp the principle of its movement. Many of these problems, physicists and mechanics can not yet be clearly articulated. In studying this issue, Jim Papad opoulos, a professor of engineering at the University of Northern Illinois, found that historically 25 scientists attempting to explain the stability of bicycles have proposed 25 equations, three of which are correct and two are close Correctly, 20 are the actual assumptions of the detachment. However, there is no one on the bike
