Bolzano lecture by prof. Kip S. Thorne

American physicist Kip S. Thorne, recipient of the Nobel Prize for 2017 for detection of gravitational waves, visited Prague at the invitation of he Learned Society. He held a series of “Bolzano lectures” and a lecture titled “Creating Gravitational-Wave Astronomy” for the Learned Society on 15 May 2019 in the Blue Auditorium of the Carolinum. The lecture was held with the support of the Karel Janeček Foundation and was received very enthusiastically.
