What was once truth becomes false

Two Australian surgeons found that half of the facts in that field also become false every forty-five years. As the French scientists noted, all of these results verify the first half of a well-known medical aphorism by John Hughlings Jackson, a British neurologist in the nineteenth and early twentieth centuries: "It takes 50 years to get a wrong idea out of medicine, and 100 years a right one into medicine." ... Max Plank codified this in a maxim: "New scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it."

~Sam Arbesman's book The Half-Life of Facts
