Lesson n. three from my Masters degree
Surprisingly few people employ computational approaches in their work. People who build models usually do so without any direct confirmation, and people who run experiments either do not concern themselves with computations, or outright despise them. The number of scientist who can bridge this gap turned out to be much smaller than I expected initially.
Which makes it a very nice "blue ocean" for those willing to put in the time and efforts into learning both sides of the problem. I hope to pull this off in my PhD.
