“After Elsa’s death, Einstein established a routine that as the years passed varied less and less. Breakfast between 9 and 10 was followed by a walk to the institute. After working until 1pm he would return home for lunch and a nap. Afterwards he would work in his study until dinner between 6.30 and 7pm. If not entertaining guests, he would return to work until he went to bed between 11 and 12. He rarely went to the theatre or to a concert, and unlike Bohr, hardly ever watched a movie. He was, Einstein said in 1936, ‘living in the kind of solitude that is painful in one’s youth but in one’s more mature years is delicious’.”

“Marriage is,’ Einstein said later, ‘the unsuccessful attempt to make something lasting out of an incident.”
