What is Computational Thinking?

“Computational thinking is a way humans solve problems; it is not trying to get humans to think like computers.” “Computational thinking is using heuristic reasoning to discover a solution.” J. Wing

A CERTAIN WAY OF SOLVING PROBLEMS

What is Grad School?

Why I Chose Grad School• A. I wanted to conduct experiments

that I was interested in and would (eventually) make a difference in how science works in the “real” world.

• B. I was bored at work.• C. I was crazy.• D. I love to learn.• E. All of the above
