(e)Xtend ChemEd X looks outside the resources available at ChemEd X to items of interest to the community throughout the internet.
Xtend includes Picks, which includes a short description of books, articles, journals, magazines, and web items that our contributors and staff find interesting, professional development events, tweets, and news feeds.
This little book is a gem. I have to admit that most of the students who have completed my first physical chemistry semester, which is all about thermodynamics, would benefit from reading this wonderful explanation of the central place that these topics play in every aspect of life.
One of the most memorable experiences of my youth was when I was camping in the Mojave Desert. Having lived all of my life up to that time in Los Angeles, I had never seen a truly dark night. Lying under the stars, I found it very difficult to close my eyes because of the extraordinary beauty of the sky, full of stars and planets - the Milky Way clearly visible.
Is there something wrong with American schools?
Like Malcolm Gladwell s Tipping Point , Nassim Taleb s Black Swan threatens to become a permanent part of the lexicon. In this best-selling book, he makes the argument that evolution has prepared us to over-emphasize continuous, Gaussian relationships because they occur much more frequently than do rare but momentous, unpredictable events.
What were personal qualities of the greatest scientist of the twentieth century that differentiated him from his contemporaries? I have read a lot of books about Albert Einstein, who was one of my childhood heroes (along with the Lone Ranger).
The first of this series of books by Edward Tufte, "The Visual Display of Quantitative Information" was the one that, in my opinion, would be of most practical use to the average scientist. That was six volumes and twenty four years ago. I would recommend the most recent one, "Beautiful Information", as a logical continuation.
The folly of spending more per liter to buy water than gasoline has been mentioned in Hal's Picks previously (July 2003). That article, by Michael Schermer, emphasized the waste of money that this boondoggle constitutes. In the New York Times magazine this week is another argument against the practice, and that is its impact on the environment.
One of my picks last year was the frontal attack of an atheist scientist on religion. It was Richard Dawkins' popular "The God Delusion". This month, my choice is a respectful and conciliatory appeal by entomologist E. O. Wilson for common cause between religion and science in the preservation of what is left of Eden.
The currently accepted formal definition of a mole is the number of carbon-12 atoms in exactly 12 grams of the pure substace. This is not a good operational definition, however, because it takes too long to find, purify, and count all those atoms. The best experimental value is based on x-ray diffraction experiments on silicon crystals and puts the number within 0.0000010 of 6.0221415 x 10^23.
Neil Downie runs a Saturday science program for kids in Guildford, UK, that appears to be the most fun that anybody could have. This book is the third in a series that describes projects that he has invented for kids to build and investigate (often with the help of an adult).
