- Taking courses is OK, but not very cost effective. I would recommend
- reading a few highly technical articles in each field, and then spending a
- lot of time thinking about it and figuring out what it really means.
-
- For example, they don't teach you in school that the brain is the dumbest
- organ in the body.
-
- If you look at DNA as ROM (read only memory), there's nearly a gigabyte in
- every human cell. The machinery of the cell uses that ROM to carry out
- biological processes just as a computer uses it's memory to carry out much
- simpler tasks. Saying that cells are computers is not an analogy or a
- metaphor, cells ARE computers (and a lot more).
-
- Of all the cells in the body, neurons have the smallest amount of DNA per
- unit mass, because they just keep growing and growing without (re)producing
- any new DNA (mitochondria excepted).
-
- As we get older, brain mass stays relatively constant, but we keep loosing
- neurons and DNA. Surviving neurons just grow bigger. This produces severe
- bandwidth limitation problems in the cellular machinery. One nucleus with
- a limited capacity for transmitting instructions is asked to service a
- larger and larger cell.
-
- Almost all of the computing power in the human body is at the intra-
- cellular lever. A very small percentage is at the macro-cellular lever,
- and some of that is carried out by neuron firings.
