Learning is about creating patterns in the brain between neurons.
These patterns help solve questions or challenges that the brain is familiar with.
These patterns are learnt first by concentrating on the problem and allowing the brain to diffuse think about these ideas to attempt to find solutions.
Once these patterns are established, they have to be committed to memory by spaced repetition or reminding about these ideas in intervals.
There are many ways people learn. I think I learn best by doing and trying out the options.
Often the fundamental ideas that are required for the efficient tries need reading and learning by seeing.
