If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those live in present.
— Wittgenstein

If you concentrate on a meaningful work now and here, you preserve your infinity. (No explanation here.)

And a heaven in a wild
Hold infinity in a palm of your hand
And eternity in an hour

The Nobel Prize in Physics in 1956
Bardeen brought only one of his three children to the Nobel Prize ceremony. His two sons were studying at Harvard University, and Bardeen didn’t wanted to disrupt their studies. King Gustav scolded Bardeen because of this, and Bardeen assured the King that the next time he would bring all his children to the ceremony.
The Nobel Prize in Physics in 1972
In 1972, John Bardeen shared the Nobel Prize in Physics with Leon Neil Cooper of Brown University and John Robert Schrieffer of the University of Pennsylvania for their jointly developed theory of superconductivity, usually called the BCS-theory.
Bardeen did bring all his children to the Nobel Prize ceremony in Stockholm, Sweden.
