The frontier of scientific knowledge, often referred to as the cutting edge, is reached with maps drawn by earlier investigators. As Louis Pasteur said in 1854, “Fortune favors only the prepared mind.” Since he wrote this, the roads to the frontier have greatly lengthened, and there is an enormously larger population of scientists who travel to get there. There is a compensation for you in your journey, however. The frontier is also vastly wider now, and it grows more so constantly. Long stretches along it remain sparsely populated,
Like a growing circle with an expanding circumference.
