I recently stumbled on an old article. It was a nice read about the scientific pursuit, a treasure trove of neverending question that need answers. Read Why the Pursuit of Scientific Knowledge Will Never End.
It also reminded me of a quote I had read some time back, which I think is relevant here.
Mistakes are, after all, the foundations of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not.
– Carl G. Jung
