A Short History of Nearly Everything by Bill Bryson

A Short History of Nearly Everything
Bill Bryson (2004)

Just finished reading this delightful survey of modern scientific thought and the history of how we got here. Some of the biographical vignettes are truly inspiring, and others heartbreaking.

I found only one area where recent discovery has superseded his account—so called “junk” DNA. It is now known that these areas perform important regulatory functions and are anything but junk!

This book should be required reading by every high school senior or college freshman! It does more to explicate science and scientists than any watered-down textbook ever could.

Clair Cameron Patterson, the Age of the Earth, and Environmental Lead

I’m currently reading A Short History of Nearly Everything by Bill Bryson. About a third of the way in he introduces Clair Cameron Patterson who could be the model of the modern citizen/scientist.

Here is a short synopsis of his career: Born in Iowa; attended Grinnell College, U of Iowa, U of Chicago; participated in the Manhattan Project to build the first Atomic Bomb, studied isotope decay in terrestrial rocks and meteorites to establish the age of the earth at 4.5 billion years; noticed during that research that all his samples were contaminated with lead; discovered that the lead was in the very air we breathe as a result of leaded gasoline and industrial processes; suffered at the hands of the powerful Ethyl Corporation and malicious bureaucratic forces; stood his ground and ultimately prevailed; lived to see lead removed from fuel and many other manufactured goods.

We can all breathe easier!

Yucatan Trip 2009 – Uxmal Ruins

Just back from a short vacation in the Yucatan with my brother and sister-in-law. We started and ended our tip at Merida, which has a delightful old city center to explore. [photo gallery] First on our list was Uxmal, my personal favorite! Located in the gently rolling Puuc Hills, it is one of several significant Late Classic Mayan centers in that area. [photo gallery]

The so-called Pyramid of the Magician dominates the modern entrance to the site (showing its less elaborate back side). The main temple entrance takes the form of a huge mouth, still intimidating even today. The pyramid was actually built in five stages, each covering older parts of the structure. Next to this lies the Nunnery Quadrangle, actually a palace or government building, with its cross-hatched facades and numerous masks.

The site has many other attractions including: a huge rectangular building called the Governor’s Palace; a taller Grand Pyramid that sort of blends into the forest; the Dovecote Temple; a Ball Court; and a double-headed Jaguar Throne. There were also plenty of lizards and birds in residence. Here’s a panorama from the top of the Grand Pyramid (large file).

The site had many intact rooms, all based on the Corbel Arch. The example shown here is particularly beautiful/impressive. Note how the walls gently curve toward the center where the tiny “ceiling” fills the gap.

Apparently there is new insight into the ubiquitous masks at Uxmal, Chichen Itza, and other Mayan sites in the Yucatan. Rather than representing the rain god Chaac, scholars propose that they denote hill or mountain beings (witz) and confer sacred status to the structures on which they appear.
