As a physicist who has recently infiltrated the ranks of the American Chemical Society, I was amused to see the letter by Ted Logan dealing with the "energy challenge," which states that chemistry has "the people and the talent to do the job better than any other discipline" (C&EN, Dec.12, 2005, page 4). In the following paragraph, we find that "20 TW equals 20 times 1010 [100-W] bulbs burning for a year." Actually, there is a stunning level of confusion here between energy and power, which leads me to believe that physicists will still be needed to explain these concepts for years to come!
