Researchers’ Night in Dolni Brezany

Researchers’ Night, an event that brings to life hundreds of scientific buildings in one evening that are inaccessible to the average mortal. Visitors cruise through labs, lecture rooms, exploding experiments and go in-depth on current topics. Kids, adults, seniors, anyone passionate about science is welcome.

Meet our scientists on Friday, 24 September 2021 and they’ll teach you to love science 😉

This year’s theme for Scientists’ Night is time. The programme has been prepared in cooperation with the ELI Beamlines laser centre and the Institute of Physics of the CAS.



  • Lecture Lasers and Time |18:15| Jan Kaufman will take you into the remarkable world of lasers – you will learn how short time moments we are able to create with lasers and where to take advantage of it. Thanks to lasers, we can measure the exact distance of the Moon from the Earth or take ultrafast photographs of cellular processes; the lecture will last about 45 minutes, in Czech language only.
  • Guided Tours in CZ |18:00| 18:45| 19:30| 20:15| 21:00| 21:30 | you will have a look into the experimental halls of the HiLASE Centre and learn what our lasers are used for; the length of the tour is approx. 45 minutes
  • Guided Tour in English | 20:00
  • Interesting accompanying programme for children and adults |18:00 – 22:00| come and turn into James Bond in a real laser maze, exercise your brain in the laser maze game or see if you can shoot faster than a laser 😉

The Researchers’ Night has been held in the Czech Republic since 2005 and the HiLASE Centre is not to be missed! Together with us, universities, institutes, observatories and other institutions join the event. In 2020, the coordinators (University of Ostrava and VŠB – TUO) succeeded in obtaining the prestigious European Marie Curie-Skłodowska project, thanks to which the Czech Researchers’ Night is also on the European map.
