Richard Bellman said :
"The 1950s were not good years for mathematical research. We had a very interesting gentleman in Washington named Wilson. He was Secretary of Defense, and he actually had a pathological fear and hatred of the word research."
Basically he said army and politicians hated the maths and research. That's why he named it : dynamic programming.
But why ? According to my knowledge in WW2 had a lot of progress in maths and research : linear programming (simplex method), conditional probability (enigma machine), AI(it was basically maths research). So even with those achievements, why did they hate maths in 1950?
Honestly I didn't found this information on web (or maybe I don't know how ask to google)
