Arthur Holly Compton, WashU’s ninth chancellor, conducted X-ray scattering experiments in 1922 that demonstrated the particle nature of electromagnetic radiation. At the time, the idea that light had both wave and particle properties was not easily accepted. His discovery stimulated the development of quantum mechanics and was recognized with the Nobel Prize in 1927.
Physicist Errando helps NASA solve black hole jet mystery

Thirsty wheat needed new water management strategy in ancient China
|
Research from the laboratory of archaeologist Xinyi Liu in Arts & Sciences shows that a practice of purposeful water management, or irrigation, was adopted to help cultivate wheat in northern China about 4,000 years ago.
Polarized X-rays reveal shape, orientation of extremely hot matter around black hole
|
New measurements from Cygnus X-1, reported Nov. 3 in the journal Science, represent the first observations of a mass-accreting black hole from the Imaging X-Ray Polarimetry Explorer (IXPE) mission, an international collaboration between NASA and the Italian Space Agency. The lead author of the new study is physicist Henric Krawczynski in Arts & Sciences.
