science. Daytime science is made of the polished, linear, rigorous stories you can read in a journal such as this one, or hear in talks. Night-time science is the messy heap of intuition, despair or elation, association of seemingly unrelated ideas, absolute absence of rigour, that feeds daytime science. To me, night-time science is the creative, exciting bit. The polishing, rigor, and so on, however, are not just a mere ‘professional packaging’ of the product. Night-time science will produce a fleeting thought, daytime science will formalise it into a long lasting mental representation from which novel concepts can emerge.
