"Good questions outrank easy answers."

from MIT News
"In a career that spanned seven decades, [Samuelson] transformed his field, influenced millions of students, and turned MIT into an economics powerhouse.

from the New York Times

"The first American Nobel laureate in economics, the foremost academic economist of the 20th century...  In receiving the Nobel Prize in 1970, Mr. Samuelson was credited with transforming his discipline from one that ruminates about economic issues to one that solves problems, answering questions about cause and effect with mathematical rigor and clarity."
