Understanding how little we know is crucial to gaining knowledge.

In general, people accumulate knowledge gradually over a long period of time. However, there are extraordinary people all around us, who are capable of accumulating impressive amounts of knowledge within a relatively short period of time.

Let us consider, for example, some ideas of Nikola Tesla that have not been implemented as of yet.

Spreading knowledge is the most effective weapon for defeating ignorance.
