Event Description

Born in Sweden in 1814, Anders Ångström was a physicist, solar astronomer and a pioneer in the field of spectroscopy. He was among the first scientists to identify hydrogen in the Sun’s atmosphere and to examine the spectrum of the Aurora Borealis.  To express the wavelengths of electromagnetic radiation, Ångström used a unit of length equal to one hundred-millionth of a centimeter, which was later called “ångström” or “angstrom” in his honor. “Ångström” is the topic for Utah State University’s Science Unwrapped program Friday, March 22, with featured speaker Sean Johnson, associate professor in USU’s Department of Chemistry and Biochemistry and associate dean in the College of Science. “We’re going to examine the atomic world,” says Johnson, who specializes in structural biology and x-ray crystallography. “We’ll take a look ‘under the hood’ to investigate structures of this scale.”
