A study of Nobel Laureates from 1901 to 2008 in these three fields examined the age at which scientists did their prize-winning work.
Results showed that before 1905, about two-thirds of winners in all three fields did their prize-winning work before age 40, and about 20 percent did it before age 30.
But by 2000, great achievements before age 30 nearly never occurred in any of the three fields. In physics, great achievements by age 40 only occurred in 19 percent of cases by the year 2000, and in chemistry, it nearly never occurred.
“Today, the average age at which physicists do their Nobel Prize winning work is 48. Very little breakthrough work is done by physicists under 30.
The researchers believe the reasons for the age shift have to do with both the type of breakthroughs honored – theoretical or experimental – and how long it takes scientists to receive their training and begin their career.
