Two heroes in the pantheon of inventors are Thomas Edison and Nikola Tesla. Of their many contrasts an often overlooked one is their divergent approaches for how to solve problems. The book Empire of Light is a fantastic telling of the entire story of American electricity, and Edison and Tesla’s initial partnership and later rivalry, but it also touches on the attitudes about invention.
Edison is famous for his affirmations of hard work as the key ingredient in invention:
- “Genius is one percent inspiration and ninety-nine per cent perspiration”
- “I have not failed 700 times. I have not failed once. I have succeeded in proving that those 700 ways will not work. When I have eliminated the ways that will not work, I will find the way that will work”
It’s good advice. Finding the idea for something is rarely the hardest part in bringing it into the world. Instead, it’s the willingness to work on the long list of little issues that must be solved to bring an idea to fruition (or the marketplace). In problem solving lingo, this kind of approach is called brute-force. You apply great energy to exhaustively try out every different alternative.
Tesla had a different approach. His intuitive understanding of the principles of science allowed him to think about problems in ways Edison either could not, or did not want to. Tesla wrote:
- “If Edison had a needle to find in a haystack, he would proceed at once… to examine straw after straw until he found the object of his search. I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.”
The best approach to problem solving is synthetic: to use the synthesis of both ways of thinking to serve you. You should be willing to apply brute-force, but also be willing to do thinking in advance to make solving a problem easier.
Decades ago, in my computer science classes, there was a clear divide among my programmer peers. When given a new assignment, some would jump right in to writing code. I’d call them little Edisons. Others would put the keyboard away, and think for a while on paper. They’d sketch things out, and perhaps ask a question or two online. These were the little Teslas.
Which one do you tend to be more like in how you approach problems?
