XXV. General Assembly of the Learned Society of the Czech Republic

The ceremonial part of the XXV. General Assembly of the Learned Society, at which the Medals of the Learned Society of the Czech Republic Societas Scientarium Bohemica Ad Laudem et Honorem and the awards of the Learned Society of the Czech Republic in the “Young Scientist” and “Grammar School Student” categories were presented, took place on Monday 20 May 2019 in the Great Hall of the Carolinum.


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.


XXV. General Assembly

The Czech Learned Society is holding its XXV. General Assembly on 20 and 21 May 2019. The Learned Society’s awards in the “Young Scientist” and “Grammar School Student” categories, Teaching Awards for pedagogic workers who promote interest in science and research at grammar schools and the Learned Society’s medals for meritorious contributions to the advance of science will be presented during a ceremony on 20 May at the Karolinum. Lectures by renowned scientists will also be presented. The second day will be reserved for the working part of the meeting, in the building of the Academy of Sciences of the Czech Republic.
