In May and June, APS presented two plaques as part of its historic sites initiative. The one in May honored the Davisson-Germer experiment, performed in 1927 at the then site of Bell Labs in lower Manhattan; and  the one in June recognized the Keeling Curve describing the rise of carbon dioxide in the atmosphere, research that was done by Charles David Keeling at the Scripps Institution of Oceanography in San Diego.
