The steepest grade on U.S. main-line track is at the small town of Saluda, on a Norfolk Southern route between Spartanburg, South Carolina, and Asheville, North Carolina. The grade goes on for three miles at a slope of 4 or 5 percent. Trains have not been running on the line since 2001, but the tracks are still maintained.
For those who've never experienced a sunrise in the rural Midwest, it's roughly as soft and romantic as someone's abruptly hitting the lights in a dark room. This is because the land is so flat that there is nothing to impede or gradualize the sun's appearance. It's just all of a sudden there.
I’m a historian of innovation. I write mostly about the causes of Britain’s Industrial Revolution, focusing on the lives of the individual innovators who made it happen. I’m interested in everything from the exploits of sixteenth-century alchemists to the schemes of Victorian engineers. My research explores why they became innovators, and the institutions they created to promote innovation even further.
To truly increase innovation, I think we need policies focused on what goes on even further upstream, before much of the supply of new inventors is inevitably siphoned off into distractions, dead ends, and failure. Most policies inevitably have a marginal effect, but a slight expansion of the incoming swell of potential inventors can have a much greater impact than fiddling with the incentives of the few hundred who’ve already somewhat made it to the final trickle. Increase the strength of the flow upstream, and everything downstream flows the faster too.
