"In 1887, the French railways unilaterally decided to move every clock in every railway station 5 minutes behind Paris time. Meanwhile, the clocks outside the stations remained untouched. So why on earth (or at least, in France) would you do that?" www.youtube.com/watch?v=PELr... #soFrench

"In the 1940s, when the French mathematician Jacques Hadamard asked good mathematicians how they came up with solutions to hard problems, they nearly universally answered that they didn’t think in words; neither did they think in images or equations" www.henrikkarlsson.xyz/p/wordless-t...
When is better to think without words?
Non-verbal, blurry thinking is faster and can search in a broader way, but it is more error-prone than verbal thought.
