, who discussed the issue in his book of essays, The Relativity of Wrong
The Relativity of Wrong
The Relativity of Wrong is a 1988 essay collection by Isaac Asimov, which takes its title from the most ambitious essay it contains. Like most of the essays Asimov wrote for F&SF Magazine, each one in The Relativity of Wrong begins with an autobiographical anecdote which serves to set the mood...

"When people thought the earth was flat
Flat Earth
The Flat Earth model is a belief that the Earth's shape is a plane or disk.

, they were wrong. When people thought the earth was spherical, they were wrong
Figure of the Earth

The actual topographic surface is most apparent with its variety of land forms and water areas. This is, in fact, the surface...

Asimov explains that science is both progressive and cumulative, and builds upon the mistakes of the past. Even though scientific theories are later proven wrong, the degree of their wrongness attenuates with time. Data collected from satellite measurements shows precisely how the Earth's shape differs from a perfect sphere.

According to John Jenkins, who reviewed The Relativity of Wrong, the title essay of Asimov's book is the one "which I think is important both for understanding Asimov's thinking about science and for arming oneself against the inevitable anti-science attack that one often hears — [that] theories are always preliminary and science really doesn't 'know' anything."
