“Einstein did not just wake up one morning thinking that nothing was faster than light, nor did Copernicus simply think up the idea that the Earth orbits the sun, Darwin that species evolve. New ideas do not just fall from the sky. They are born from a deep immersion in contemporary knowledge. From making that knowledge intensely your own, to the point where you are living immersed in it, from endlessly turning over the unanswered questions, trying all roads to a solution, then again trying all roads to a solution, and then trying all those roads again. Until there, where we least expected it we discover a gap, a fissure, a way through, something that no body had noticed before, but that is not in contradiction with what we know, something miniscule on which to exert leverage, to scratch the smooth, and unreliable edge of our unfathomable ignorance, to open a breach onto new territory.”
