What is Ph.D.? Yes, I know it is a prestigious academic degree. Only that? Hmm... I think NO . It's hard to describe it in words. You better focus on the illustration below: And... the things that made me fall silent is what was said by Matt, below: "If you zoom in on the boundary of human knowledge in the direction of genetics, there's something just outside humanity's reach. My wife and I chose to start funding these graduate students after we learned that our son has a rare, fatal genetic disorder. It may be too late for my son, but it's not too late for other children. Even one child suffering is one child too many. The only way to end this kind of suffering is science. And, the best way to do science is through graduate students." What a beautiful thought that touched my heart. Note: This work was originally from The Illustrated Guide to a Ph.D. by Matt Might.
