Carving Nature at the joints

David Hubel, on statistics: “We could hardly get excited about an effect so feeble as to require statistics for its demonstration.”

I came across this (below), in my end of year clear out. And even if this was 2016, rather than 2017, it is as good a thought to open 2018 with, as any other. It is from a review of “Life’s Greatest Secret: The Race to Crack the Genetic Code”, by Matthew Cobb. The review is by H Allen Orr. NYRB

Finally, and perhaps most important, Life’s Greatest Secret highlights the power of the beautiful experiment in science. Though Cobb pays less attention to this subject than he might have, the period of scientific history that he surveys was the golden age of the beautiful experiment in biology. Biologists of the time—including Nirenberg with his UUU, Crick and Brenner with their triplet code work, and others including Matthew Meselson, Franklin Stahl, and Joshua Lederberg—were masters of the sort of experiment that, through some breathtakingly simple manipulation, allowed a decisive or nearly decisive solution to what previously seemed a hopelessly complex problem. Such experiments represent a species of intellectual art that is little appreciated outside a narrow circle of scientists……..

But the larger lesson of Life’s Greatest Secret is one that may be worth remembering. When scientists require definitive answers, not merely suggestive patterns, they require experiments that are decisive and, if all goes well, beautiful.
