Beautiful Evidence + Naked Economics

   A couple of non-fiction books I've read recently ...

   1. "Beautiful Evidence" by Edward R. Tufte
     <http://www.amazon.com/Beautiful-Evidence-Tufte/dp/0961392177>

   Another interesting look at the presentation of information by Edward
   Tufte.  It brings together a lot of his earlier research, with the
   focus on how to present "beautiful evidence".  He draws examples from
   art and science over the past centuries, from Galileo and Newton to
   the modern day.

   There's an interesting critique of how Microsoft PowerPoint corrupts
   the very information it is used to present.  He cites the example of
   how PowerPoint slides adversely affected the assessment of the damage
   to the space shuttle Columbia on launch.  Excerpts from the book are
   available on the author's web site:

   2. "Naked Economics: Undressing the Dismal Science" by Charles Wheelan
     <http://www.amazon.com/Naked-Economics/dp/0393324869>

   Yet another book on economics.  I've been reading a few books on the
   subject lately, if only to reassure myself that the subject I learnt
   and enjoyed at Uni has been corrupted and perverted by modern
   politicians.

   This book tackles the basics: how markets work, and also how they can
   fail.  It looks at the role of incentives, human capital, trade and
   the supply of money.  The goal is to make economics accessible to the
   average person, and I think it succeeds quite well without getting overly
   political.

   There's a great discussion on the goals of real estate agents.  You
   would think that since they get a percentage of the final sale price,
   agents would always try to get the highest price for their client.  Not
   necessarily so, since working for a higher price will take time, and
   prevents the agent from selling more properties.  So turnover is more
   profitable for them, but that conflicts with the objective of the
   individual sellers.

   Another standout for me was that the book reminded me of the
   "Efficient market hypothesis":
     <http://en.wikipedia.org/wiki/Efficient_market_hypothesis>

   It "states that it is not possible to consistently outperform the
   market by using any information that the market already knows, except
   through luck. Information or news in the EMH is defined as anything
   that may affect prices that is unknowable in the present and thus
   appears randomly in the future."  If this is true, then all those stock
   market analysts are are effectively gambling other people's money
   in a global casino.  Unless they have access to special (inside?
   information, they appear to be just riding hunches.  Read the article
   for a critique.

   If you want to start reading about economics (the so-called "dismal
   science", this is a good start.  Here are a couple more interesting
   books:

   * "Freakonomics: A Rogue Economist Explores the Hidden Side of
      Everything" by Steven D. Levitt and Stephen J. Dubner
     <http://www.amazon.com/Freakonomics/dp/0061234001>
   Looks at the economics of the unusual, such as gangs, Sumo wrestling,
   the Ku Klux Klan, the naming of children and those sneaky real estate
   agents.

   * "The Undercover Economist: Exposing Why the Rich Are Rich, the Poor
      Are Poor--and Why You Can Never Buy a Decent Used Car!"
     by Tim Harford
     <http://www.amazon.com/Undercover-Economist/dp/0195189779>
   Looks at the price of coffee, used cars, health insurance and how
   supermarkets price products.  More focussed on the everyday things,
   it also ties everything together a bit more than Freakonomics.  Like
   "Naked Economics", the book also covers the wider economy as a whole.
