What is Ph.D
Illustrated by Matt Might
Imagine a circle that contains all of human knowledge.
By the time you finish elementary school, you know a little.
By the time you finish high school, you know a bit more.
With a bachelor’s degree, you gain a specialty.
A master’s degree deepens that specialty.
Reading research papers takes you to the edge of human knowledge.
Once you’re at the boundary, you focus.
You push at the boundary for a few years.
Until one day, the boundary gives way.
And, that dent you’ve made is called a Ph.D.
Of course, the world looks different to you now.
So, don’t forget the bigger picture. Keep pushing.
