Before the internet, I user to spend a lot of time pondering questions to which the answer was in a textbook somewhere. Sometimes I figured them out for myself.
Today, I rarely spend much time pondering questions whose answer is in Wikipedia. I just look it up.
Pondering any question is good mental exercise for others. I wonder if the easy availability of answers to most questions makes it harder to tackle the truly unsolved ones.
