This is how they say it in Serbia «Money. Freedom. Future.»
“The man that invented the 20th century” – this is how his contemporaries called the great Serb. His personality is wrapped in mysteries and his inventions and discoveries still keep the best minds of humanity restless. He is featured in books and movies, the airport in Belgrade, the capital of Serbia, is named after him. Nikola Tesla has deserved the title of the nation’s main heritage.
His greatest contribution to science was the research of alternate current and the devices that use it. He was particularly interested in high-frequency currents and experimented with himself studying their influence on human body. He was able to discover that electric current with a frequency above 700 Hz does not harm a human body but simply goes over its surface instead. This concept laid the basis for electric current therapy and is now widely used, for example, in cosmetology.
Most people, however, would associate his name not with high-frequency currents but the famous Tesla transformer circuit (also known as “the Tesla coil”). This invention can sometimes be seen at nature and science museums and exhibitions – when it operates, it initiates various gas discharges, creating very beautiful and unusual visual effects: it looks like the air is being pierced by many lightning. This invention is also popular in the movies: for example, the main character of “The Sorcerer’s Apprentice” movie plays “light organ” with the help of the Tesla coil.
Tesla was by far ahead of his time. Back then, in late 19th century, he dreamed of wireless communications and was working to put this idea into practice. Nikola Tesla always prioritized scientific goals over commercial ones, and it often prevented him from finishing his research. As a true scientist, he was always interested in finding something new, to solve another riddle while his sponsors were mostly concerned with monetization of his inventions. However, Tesla left behind many scientific works that are still being studies by his followers and fans in Serbia and all over the world.
