In Your Memory, there's an inference question: Which celestial body besides the sun causes the earth's temperature to drop? Well, first off, I notice that the sun delivers more energy to earth than everything else combined, so it can't ever cool the earth (unless he allows a major change to the current state of our solar system, or counts a lessening in received solar output as solar cooling). So the author put that there as a hint to think about what gets in the way of all that energy. The cool thing about the question is that it caused a nice moment when I realized how dependent we are on the sun, and how really convenient it is to have that large nuclear furnace there, and how nice it is that large clouds of stuff will spin, cluster, and at a certain critical mass will form a nuclear furnace, and how it's nice that Jupiter is just shy of that critical mass. I mean, what are the odds?
According to Your Memory: A User's Guide (from 1982), my previous notion of improving recollection can be done but not simply by practicing rote memorization. It's better to link knowledge to various memories.
There are three kinds of memory: short-term, long-term, and sensory. Short-term isn't understood well in 1982 and is just working memory. Long-term memory is comprised of episodic memory (your personal daily happenings, incidents, experiences) and semantic memory (facts, formulae, tables, words and their meanings). Sensory memory is the memory of sights, sounds, tastes, touches, and smells.
People normally index memories by either sight or sound, converting data into one format for indexing. Individuals with greater powers of recollection typically index memories with multiple senses. Alexander Luria wrote about Shereshevskii who has the following quote about a 2000Hz tone: It looks something like fireworks tinged with a pink-red hue. The strip of color feels rough and unpleasant, and it has an ugly taste - rather like that of a briny pickle ... you could hurt your hand on this.
If you want to improve your memory:
|Nighttime||Organize important memories of the day|
Tie them to different senses
Write them in journal
Of Permanent Value is 1000+ pages long, but only has about 700 pages of text as most chapters are a page long. Regardless, it has a bunch of very good info that I've not found elsewhere.
The Money Masters and The New Money Masters are good overviews of the "major" investment ideas. The first book was brought out in 1980 and the second in 1989.
Money algorithms (Jim Rogers is in The New Money Masters):
|Graham||Buy company at 50% of working capital, sell at 100%|
|Buffett||Pay a fair price for a great company (this isn't everything)|
|Fisher||Thing long-term prospects, buy and hold|
|T. Rowe Price||Buy growth stocks|
|Templeton||Go international for value|
|Jim Rogers||Invest based on macroeconomics|
|Peter Lynch||Buy baskets of promising sectors, whittle as some firms succeed.|
