“had prepared myself for the likelihood that I would fail. In fact, the entire field of theoretical physics prepares you to cope with disappointments and failure. For theoretical physicists, a best-case scenario is one where only nine out of ten of your ideas are wrong—and even then, most of us never know that we were correct one-tenth of the time, because opportunities for theoretical physicists to test their new ideas observationally are rare. But where observations fail, the scrutiny of peers comes to the rescue. The theoretical physics community operates like an extended family. The bond among its members is based not on blood but on a deep respect for one another’s views. Of course, as in any family, respect has to be earned the hard way—in our case, by contributing to groundbreaking ideas and advancing knowledge. To that end, we scrutinize, criticize, and work hard to pinpoint logical flaws in the ideas of our colleagues as well as in our own. Even if we rip apart each other’s reasoning, we remain united by our shared pursuit of the same goal: to learn the true answer to the mysteries of nature.”
