Think Like a Freak



Freaknomics authors Steven D. Levitt and Stephen J. Dubner tackle more perplexing problems with their new book, Think Like a Freak. Of the the three books, they have produced this one is less flippant and more nuanced.  The authors acknowledge that many problems in this world are incredibly complex and do not lend themselves to simple solutions.

The authors did help solve one of the more perplexing additions to their previous book.  In Super Freakonomics they added a section to the book on why terrorists should by life insurance from their bank.  They came up with an algorithm that could identify the unusual banking activities of terrorists with greater than 99% accuracy.  Unfortunately this still included a large number of innocent individuals.  They wanted the terrorists to reveal themselves by buying life insurance from a bank because almost no one buys life insurance from a bank.

They also describe the paradigm shift in the approach to eating hot dogs that allowed one man to double the previous record for the number of hot dogs eaten.  He broke down the task into parts discovering that moistening the bun with water made it go down quicker.  Eating the dog from the side sped up the chewing. This has implications for process improvement. We need to take a fresh look at how we do things and determine different ways of accomplishing the task. 

They encourage individuals to approach problems with intense child like curiosity.  It frees people from normal constraints and ways of looking at problems.

The Elements by Theodore Gray


Theodore Gray's book  The Elements: A Visual Exploration of Every Known Atom in the Universe , provides a humorously informative and visually interesting introduction to the known natural and man made elements on the periodic table.  Most elements have two to four pages packed with information about the elements usefulness, it's discovery and some health and safety information.

Sodium and other alkali metals are known to react strongly to water.  As part of my job, I've had to respond to the aftermath of this reaction.  The researcher in this case was safe but the lab was a mess.

I enjoyed his explanation of the relative amount of elements on the earth.  For example almost all of the helium on earth has originated from alpha particle radioactive decay of two protons and two neutrons. 

I have included a sample page from one of my favorite elements.  Even though Gallium's gray color fails to distinguish itself from many other metals, it has the unique property of melting just above room temperature.  This was the basis of Sam Kean's book, The Disappearing Spoon.

A World Without Time - Maggie Carlson


My daughter completed writing her first book last fall.  It's now available for Amazon Kindle at this link A World Without Time by Maggie Carlson.

The book is a fast paced adventure that gets rolling when three students on a field trip get separated from their group.  They mistakenly set off an experiment that traps the three of them in a world without time.

They learn to rely on each other as they overcome many obstacles on their quest to find the inventor who can stop the experiment and bring back time.

The cover photo was taken this spring while we were touring Cave in the Mounds Park in Wisconsin.

Linked




Albert-Laszlo Barabasi compares the linked nature of the web to the rest of our world.  Web hubs and links are not created equal.  Web link traffic like income distribution and job performance follow a power law curve and not a bell curve distribution.

A bell Curve distribution would assume that traffic to websites would only have a few sites with high number of hits and a few sites with a low number of hits.

The power law distribution shows a few websites (Google, Amazon) having a lot of traffic and many websites (personal, research) having little or no traffic.

This also has implications for disease management. In the spread of STD's there are individuals who have 1000's of partners and controlling their behavior or contacts has a much greater impact than focusing on individuals with one or two partners.
