The Kopřivnice Days of Technology, held at the end of May at the Tatra Trucks test track in Kopřivnice, once again offered visitors a varied programme combining technology, education and hands-on demonstrations. Colleagues from CEET were also among the exhibitors. At the stand of the Centre for Nanotechnology, visitors had the chance to see that science does not have to remain confined to laboratories and academic papers. It can also be understandable, playful and closely connected to everyday life.
Although the weather during the event was far from ideal, it did not discourage visitors. Children, parents and adults interested in technology and natural sciences all stopped by the stand dedicated to the microscopic world. The main attraction was a digital optical microscope, which made it possible to observe objects we usually pass by without much notice. Seen up close, however, they turned into intricate landscapes full of shapes, structures and hidden details.
Visitors could examine various types of insects, plant flowers and pollen grains. Objects like these clearly show how precisely nature works. The surface of wings, the tiny hairs on an insect’s body, the delicate structure of a flower or the shape of a pollen grain are not random. Every detail has a purpose, it may help with movement, protection, reproduction or the capture of particles. The microscope therefore allowed visitors to look at familiar things in a different way: not merely as ordinary insects or flowers, but as the result of long-term development and remarkable adaptation to the environment.
The educational memory game also attracted considerable interest, as it connected nature, microscopy and modern technologies. Participants matched natural objects, such as a lotus leaf, a burdock or an octopus, with their enlarged microscopic structures and then with technical applications inspired by these natural patterns.
The participation of the Centre for Nanotechnology in the Kopřivnice Days of Technology therefore had both a presentation and an educational dimension. It showed that science communication is most effective when it links expert knowledge with direct experience. A visitor who sees a pollen grain or the structure of an insect’s body with their own eyes can much more easily understand why scientists study materials, surfaces and structures at the microscopic scale.
