“A book published during the presidency of Chester A. Arthur has a greater chance of being in print today than one published during the time of Reagan.”
“In the basement of Madrid’s Reina Sofia museum, a giant robotic machine painstakingly scans a painting by Catalan surrealist artist Joan Miro, slowly snapping hundreds of microscopic shots. The pictures taken by the machine, which uses infrared and ultraviolet photography, will help experts determine the condition of the 1974 oil on canvas painting in unprecedented detail. The device lets restorers see cracks, scratches and creases as well underlying preparatory sketches and all subsequent touch-ups that would be otherwise undetectable. The robot can work unsupervised round-the-clock and can be controlled by a computer from a remote location.”
