Friday with Physics at the ‘Week of Science and Technology 2014’

podujatie Piatok s fyzikouThe event Friday with Physics took place on Friday 14 November 2014 as one of the main events of the Week of Science and Technology in Slovakia 2014 in the Slovak Centre of Scientific and Technical Information, Lamačská cesta 8/A in Bratislava. This event was held under the auspices of the Ministry of Education, Science, Research and Sports of the Slovak Republic.

The aim of this event was to bring physics closer to the public through the work of the world-renowned physicist and inventor – Nikola Tesla.

Lecture topic: Can we get the energy for free? Myths and rumors in the story of the legendary Nikola Tesla.

Guests of the event were prof. Ing. Peter Ballo, PhD., and his assistant Ing. Patrik Novák, both from the Institute of Nuclear and Physical Engineering at the Faculty of Electrical Engineering and Information Technology, Slovak University of Technology in Bratislava.

In the lectures, they presented specific examples, which point out to the relationship between energy and space. Moreover, the guests also discussed the possibilities of obtaining energy from various sources. The lecture was also enhanced by a demonstration of the Tesla Coil, whose operation is accompanied by very interesting acoustic and visual effects.

The lectures were devoted to the life and work of the brilliant engineer Nikola Tesla, whose discoveries still fascinate the whole world today. Many consider him to be a talented visionary, but also an enigmatic scientist. Through his discoveries, he was able to see things far into the future, and literally overtook an era. In 1890, he constructed a gas discharge lamp, which was electrodeless. A year later, he began to deal with radio transmission technology and after a short time, he was first in the world to publicly demonstrate a radio communication device. Nevertheless, he remained unappreciated in many ways, because a good bit of his discoveries originated as a byproduct of his primary research, without realizing their future potential. For example, he has observed cathode rays a lot earlier before they were “reinvented” by Wilhelm Conrad Röntgen. It is even possible that he had constructed the laser, more than half a century before its proven discovery. However, Tesla focused his lifelong research on the energy and its (wireless) transmission through the air. What did the legendary Tesla actually invented in terms of the energy transmission? Is it possible to get energy out of nothing? Why even after more than 70 years after his death many of his inventions remain largely unknown?

What was Nikola Tesla like? He was a complicated person, hardworking, a visionary, a genius. He used to sleep three hours a day, he was not practical with money, he was a gambler, quarrelsome, because others did not understand him, but he was also generous and aroused the interest in Albert Einstein. However, he died forgotten. To conclude, professor Ing. Peter Ballo articulated the lesson that ensued from the lecture: “Everyone has a talent that should be encouraged, but the era of geniuses-individuals has passed and today’s engineers have to work together and cooperate.

Friday with Physics was divided into two separate lectures with the same topic. The morning lecture (at 9AM) was devoted to organized groups from high schools, while the afternoon (at 5PM) lecture was devoted to the general public.
