How Kepler Invented Science Fiction and Defended His Mother in a Witchcraft Trial While Revolutionizing Our Understanding of the Universe

How many revolutions does the cog of culture make before a new truth about reality catches into gear?

BY MARIA POPOVA

This essay is adapted from Figuring.

This is how I picture it:

A spindly middle-aged mathematician with a soaring mind, a sunken heart, and bad skin is being thrown about the back of a carriage in the bone-hollowing cold of a German January. Since his youth, he has been inscribing into family books and friendship albums his personal motto, borrowed from a verse by the ancient poet Perseus: “O the cares of man, how much of everything is futile.” He has weathered personal tragedies that would level most. He is now racing through the icy alabaster expanse of the countryside in the precarious hope of averting another: Four days after Christmas and two days after his forty-fourth birthday, a letter from his sister has informed him that their widowed mother is on trial for witchcraft — a fact for which he holds himself responsible.
