ChemEd X contributors and staff members are continually coming across items of interest that they feel others may wish to know about. Picks include, but need not be limited to, books, magazines, journals, articles, apps—most anything that has a link to it can qualify.
Many Picks can be purchased from Amazon. Using the Amazon links on those pages help to support ChemEd X.
No, phosphorus did not jump to a new position in the periodic table - it is still element number 15.
Malcolm Gladwell has done it again. This article is very much in the spirit of the books by Henry Petroski, who has written about the engineering hidden in ordinary objects such as paperclips and pencils.
Professor James Collman of Stanford University has provided an excellent resource for all of us who try to help our students and the general public to discriminate between valid science and the bogus "scientific" claims that pervade television, the Internet, the grocery store, and especially the "health food" store.
For a long time, it could be said that with some validity that drugs not help athletes perform better. That is no longer the case. It is could increasingly difficult to assure that amateur athletes, even high school athletes, are not training and competing with the aid of testosterone and its precursors, or erythropoetin.
I've been reading a lot lately about alchemy, and was therefore delighted to find a new book on the history of chemistry (that includes some on alchemy), just published by Johns Hopkins University Press. Trevor Levere takes on the impossible task of chronicling the developments in chemistry from its beginning to the present, in only a little over 200 pages.
As a physical chemist, I was amazed when it was discovered that the diatomic free radical, nitric oxide (NO) was intimately involved in the transmission of neurological information in mammals. Now a group led by Barry Trimmer at Tufts University has demonstrated that it is the key that turns on bioluminescence in fireflies.
What do you think of when someone mentions DDT (dichloro-diphenyl-trichlorethane)? Chances are that your mind immediately goes to the damage the use of this chemical has done to bird populations, Rachel Carson's "Silent Spring", and the effort to ban or control its use.
"Brunelleschi's Dome" is an excellent example of technology in an historical context. The author, Ross King, focuses on one of the great achievements of medieval technology, the construction of the dome of the cathedral Santa Maria del Fiore, in Florence, Italy.
The word "Surviving" should probably be underlined in the title of this first-hand account by an American astro/cosmonaut of his experiences aboard Mir. There is precious little science in this book, but a great deal about living at the mercy of technology and Russian bureaucracy.
Try this! Take two identical cans of soda (or some other beverage). Roll then down a slight incline to confirm that they roll at about the same speed. What do you think will happen if you shake up one can and roll them again? Make a prediction. Then try it. Have your students do it. Develop hypotheses and test them. This is a terrific experiment that anyone can do.
