Scheffer, M. 2014. The forgotten half of scientific thinking. Proceedings of the National Academy of Sciences of the United States of America 111:6119, [full text].
Quote: "The idea that taking walks, reading things unrelated to your research, and hanging out with strangers in a campus pub should be considered part of the serious process of thinking, but might well meet with skepticism in practice.
Should we really set time and space apart for things that distract us from our jobs? Yes we should, because many of the breakthroughs in science were made by people who were distracted."
