Polymaths are people with a deep knowledge of multiple academic fields, and often various other interests as well, especially artistic, but sometimes even things like tropical exploring. Here I will focus on acquiring deep knowledge about academic fields, and why copyright reform is necessary to increase the number of polymaths in the world.
What is the fastest way to learn about some field of study? There are a few methods of learning, 1) listening to speeches/lectures/podcasts and the like, 2) reading, 3) figuring out things oneself. The last method will not work well for any established academic field. It takes too long to work out all the things other people have already worked out, if indeed it can be done at all. Many experiments are not possible to do oneself. But it can work out well for a very recent field, or some field of study that isn’t in development at all, or some field where it is very easy to work it things oneself (gather and analyze data). Using data mining from the internet is a very easy way to find out many things without having to spend money. However, usually it is faster to find someone else who has already done it. But surely programming ability is a very valuable skill to have for polymaths.
For most fields, however, this leaves either listening in some form, or reading. I have recently discussed these at greater length, so I will just summarize my findings here. Reading is by far the best choice. Not only can one read faster than one can listen, the written language is also of greater complexity, which allows for more information acquired per word, hence per time. Listening to live lectures is probably the most common way of learning by listening. It is the standard at universities. Usually these lectures last too long for one to concentrate throughout them, and if one misses something, it is not possible to go back and get it repeated. It is also not possible to skip ahead if one has already learned whatever it is the that speaker is talking about. Listening to recorded (= non-live) speech is better in both of these ways, but it is still much slower than reading. Khan Academy is probably the best way to learn things like math and physics by listening to recorded, short-length lectures. It also has built-in tests with instant feedback, and a helpful community. See also the book Salman Khan recently wrote about it.
If one seriously wants to be a polymath, one will need to learn at speeds much, much faster than the speeds that people usually learn at, even very clever people (≥2 sd above the mean). This means lots, and lots of self-study, self-directed learning, mostly in the form of reading, but not limited to reading. There are probably some things that are faster and easier to learn by having them explained in speech. Having a knowledgeable tutor surely helps in helping one make a good choice of what to read. When I started studying philosophy, I spent hundreds of hours on internet discussions forums, and from them, I acquired quite a few friends who were knowledgeable about philosophy. They helped me choose good books/texts to read to increase the speed of my learning.
Finally, there is one more way of listening that I didn’t mention, it is the one-to-one tutor-based learning. It is very fast compared to regular classroom learning, usually resulting in a 2 standard deviation improvement. But this method is unavailable for almost everybody, and so not worth discussing. Individual tutoring can be written or verbal or some mix, so it doesn’t fall under precisely one category of those mentioned before.
