I'm not that familiar with Einstein, but from what I understand this is
not a very accurate characterization of his intelligence.
Actually, Einstein did almost all of his best work when he was young.
His papers on the photoelectric effect, brownian motion, and special
relativity would any one of them have been worth a Nobel prize, all
published in his twenties. He set the foundations for quantum mechanics
and relativity, the great revolutions of 20th century physics, in just
a year or two.
After that, he slowed way down. He labored for almost two decades to
incorporate gravitation into relativity, finally producing his magnum
opus of general relativity. But that seemed to burn him out. He never
accomplished anything else of significance.
Einstein is in fact considered a notorious example of a great mind which
loses its flexibility once it gets older. He was never able to accept
quantum mechanics in its full form, tossing out one objection after
another, all of which were defeated by younger and more vital thinkers.
There have been scientists who remain active and productive throughout
their lives, people who, as David says, constantly exercise their minds
and maintain their intelligence. They are like the marathon runners of
the intellect. But Einstein was a sprinter. His early brilliance was
so impressive that we are still dazzled by it today, 100 years later.
But after that, he burned out.
I wonder whether this loss of creativity and intelligence would show
itself in his brain structure. Maybe when he was younger he would
have had more neurons, which died off to leave an apparent excess of
supportive glial cells. Maybe his brain mass would have been above
average instead of below average. Perhaps in the future we will be able
to make measurements of great minds while they are still alive and at
their peak of power.
