How to predict the outcome of a coin toss

如何预测抛硬币的结果

Coins are fair. Their tossers, less so

硬币是公平的，抛硬币的人却不那么公平

Legend holds that the city of Portland, Oregon, was nearly called Boston. A coin toss in 1845 between Francis Pettygrove, who hailed from a different Portland, in Maine, and Asa Lovejoy, from Boston (the one in Massachusetts) eventually decided the matter. 

传说俄勒冈州的波特兰市曾差点被称为波士顿。1845年，来自缅因州另一个波特兰的弗朗西斯·佩蒂格罗夫和来自波士顿（马萨诸塞州的波特兰）的阿萨·洛夫乔伊通过抛硬币决定了此事。

But things might have turned out differently, per Frantisek Bartos, a graduate student at the University of Amsterdam, if people were not such wobbly tossers.
