June 18, 1926

Allan Sandage (June 18, 1926 to November 13, 2010) was a leading American astronomer, in an era in which the United States was a world leader in such research. He was born in Iowa, and got his doctorate from Cal Tech. Sandage was throughout his long career concerned with cosmological questions and contributed his insights to questions about the age of the universe and the amount of the Hubble constant. I do not know if it is true that he became a Christian in his later years, but his is the kind of intellect that is generous and humble. He wrote the introduction to a book, published in 2001, and called Unsolved Mysteries of Science. Here are some mentioned therein:

The mysterious astronomical and calendrical achievements of the Maya suggest that degrees of knowledge depend on what is being looked for.

Scientists have failed to integrate the force of gravity within the other three fundamental forces.

Light seems to be a wave sometimes, a particle at others and the dividing line is still theoretical.

Quantum physics is haunted by a cat that is both dead and alive.

It is now certain that black holes exist but we don't really have any idea what goes on inside them.

The age of the universe is up for grabs

The mathematical possibility that every move we make creates a new universe has turned Oz into a model of reality.

....

Still, we want to know how the universe might end...
