3:30 PM | Déjà vu: Double pub in the same issue earns a retraction
Always do a careful reading of your galleys, editors. We imagine readers of Biomedical Chromatography’s special issue, “Reminiscences of Chang Kee Lim,” did some flipping back and forth when they found the same paper published twice. Here’s the resulting notice for “Determination of 4-hydroxy-2-nonenal in serum by high-performance liquid chromatography with fluorescence detection after pre-column derivatization using […]

2:51 PM | A Year in a Chemistry Developer’s Shoes
I have always seen the beauty of chemistry from a scientific standpoint: strange shapes, eye-catching patterns, giant explosions… But it was not until I came to Wolfram|Alpha that I began to appreciate just how sleek chemistry is from a programming perspective. Just a few lines of code are needed to create some of the most [...]

2:09 PM | Ice Bucket Efficiency
If you have been living on Planet Earth with an internet connection during the past month, then you can't fail to have noticed the precious bandwidth that has been devoted to streaming videos of people being soaked by a bucket of (allegedly) ice-cold water: The [insert chosen charity here] Ice-Bucket Challenge.Dubbia is for WaterIt is one of those extraordinary phenomena that transcends age, race, creed, and sanity. Everybody but everybody is getting in on the action. With the new school term […]

1:55 PM | Angst and the Empty Set
Angst and the Empty Set: Leon Horsten: Science, too, seems to suggest that there exist many “nothings” that have a positive existence: the vacuum, the number zero, and the empty set all seem to be objects with positive qualities, which can be pointed to, isolated, and manipulated. [source: mme rss]

1:47 PM | A short comment on money and independence
During the (now ironically labelled) 'Arab spring' I read Alistair Horne's A Savage War of Peace: Algeria 1954-1962. Reading the introductory chapters describing the state of the French Departments of Algeria in the first half of the twentieth century it struck me that control of the financial system was essential for a political entity to be truly democratic.  The context was that after 1848 the Mediterranean coastal region of Algeria had been administered as 3 Departments of France; […]

1:37 PM | Pre-election survey methodology: details from nine polling organizations, 1988 and 1992
This one from 1995 (with D. Stephen Voss and Gary King) was fun. For our “Why are American Presidential election campaign polls so variable when votes are so predictable?” project a few years earlier, Gary and I had analyzed individual-level survey responses from 60 pre-election polls that had been conducted by several different polling organizations.

12:50 PM | Marmellata di more 2014
Secondo tradizione inaugurata nel 2010 anche quest'anno abbiamo prodotto i nostri vasetti di marmellata di more. Ma, per la prima volta, abbiamo cambiato posto spostandoci di pochi chilometri ed sconfinando nel territorio di in un altro comune. Quello dove abita mia zia che, dallo scorso anno, ci ripete: il prossimo anno venite con me. Ed, effettivamente, la concentrazione di more, vicino a quel fontanile di abbeverazione per le vacche maremmane della zona, era molto più alta. Il che ci ha […]
