Libby right , the physical chemist who conceived of radiocarbon dating, with graduate student Ernest Anderson. Willard Libby’s concept of radiocarbon dating Willard Libby — , a professor of chemistry at the University of Chicago, began the research that led him to radiocarbon dating in He was inspired by physicist Serge Korff — of New York University, who in discovered that neutrons were produced during the bombardment of the atmosphere by cosmic rays. Korff predicted that the reaction between these neutrons and nitrogen , which predominates in the atmosphere, would produce carbon , also called radiocarbon.

But is there such a thing as a “type”? Women with feminine features, such as a smaller chin and fuller lips, tend to be deemed more appealing by both sexes, Saxton tells me, but preferences for male features are far from clear-cut.
So a disaster date might genuinely be a case of right person, wrong time. But it is possible to disrupt the trend. It seems the suggestion of heroics could also fuel a romance. A study conducted by researchers at Liverpool and Stirling Universities recruited women and 64 men, asking one group to assess images of the opposite sex with digitally added facial scars while another group viewed blemish-free mug shots. The upshot was that women rated slight scarring in a man’s face marginally more attractive when considering a short-term fling — men viewed scarring in women with indifference.
