Nikola Tesla may be not as well-known as some of his generations, such as incandescent lightbulb inventor Thomas Edison, but the engineer and discoverer is perhaps one of the most significant figures of the last 200 years. Without him, the Second Industrial Uprising might not have even been imaginable, as the electrical structures we know today would not exist.
Born in what is now Croatia, Tesla is a Serbian American who founded the use of alternating current and arranged the groundwork for much of the technology that has established common around the world. He had a wide-ranging assortment of interests, from electronics and mechanical engineering to radio waves and radiocommunication transmissions. Tesla even claimed to have fashioned a Death Beam weapon that could terminate enemy aircraft from hundreds of miles away.
With hundreds of charters to his name, Tesla created dozens of discoveries throughout his life. Even though some of them became outdated, others have stood the test of time and proved vital in shaping the technology that we still use today.
Nikola Tesla was far from the primary individual to create an electric motor. Early motors were first projected in the late 1700s, and by 1822, Michael Faraday had established that it was conceivable to create electromagnetic rotation by utilizing a magnetic wire and an electric field. Just a decade later, William Sturgeon shaped the first working DC electric motor that could turn machinery, leading to more research in the field of power machinery. These were significant ancestors that proved it was possible to generate working machines powered by electricity, with the motors altering electrical energy into mechanical force.
What Tesla established was the induction motor. Alongside Galileo Ferraris, who independently shaped his form of the induction motor, Tesla established a working model of a motor that functioned via alternating current and produced power through electromagnetic induction. Before this time, AC motors had never been constant or reliable, so this discovery would have far-reaching significance. As the current automatically reverses the poles of the magnetic field, it could transfer the motor without the need for physical linking. This made it more effective and capable of creating far more energy.
This revolutionary invention is extensively considered to be one of the most significant in history. Induction motors went on to control the electric motor market, and are the most commonly used type of motor today, accounting for more than half of all energy usage in industries. Without the induction motor, the Manufacturing Revolution would have been nowhere near as dramatic.
Nikola Tesla’s work on the induction motor similarly led to him implementing new ways of harnessing alternating current. While he didn’t discover AC power, he was one of the individuals accountable for bringing it to the public’s consideration and fought to have it more extensively adopted. The inventor patented many discoveries linked to AC motors and machines, which were ultimately purchased by George Westinghouse and his corporation, the Westinghouse Electric Corporation. Westinghouse was a big supporter of the potential for alternating current for electric power delivery and teamed up with Tesla to further progress his polyphase alternating current idea.
Guglielmo Marconi is broadly considered to be the father of modern radio. However, Nikola Tesla could also be considered to be just as significant in the growth of the technology. Tesla first started to research radio waves during the early 1890s and considered the work of German scientist Heinrich Rudolf Hertz. By 1895, Tesla believed that radio waves could be used for wireless communication and was even formulating an experiment that would have seen him send signals over 50 miles away. Regrettably, a fire demolished his lab and put a halt to Tesla’s work on radio, letting Marconi send the first radio communication in England.
Both Marconi and Tesla applied for radio-based copyrights in the late 1890s, with Tesla being presented several in the U.S. while Marconi continued to try to secure copyrights for his inventions. Ultimately, Marconi was accredited with discovering the radio, although this was eventually overturned in 1943 by the U.S. Supreme Court. What is clear is that some of Tesla’s inventions, as well as his Tesla oscillator, were vital to producing functioning radio transmitters and receivers.
The discoveries of the two engineers later transformed into what people would think of as radio and set the groundwork for wireless communication. Without them, the capability to communicate with individuals around the globe instantly would have been impossible. At one point, Tesla even recommended that radio waves could be utilized to distinguish ships at sea that couldn’t be seen. This notion would later progress into RADAR, a technology that is still very much used today and plays an important role in maritime and air security.
Radiology is a significant technique that doctors and other medical staff practice to diagnose patients and have an improved understanding of the human body. Although there are many different forms of medical imaging in use, one of the earliest and most broadly used is X-rays. This includes projecting radiation at a person, which is absorbed at different rates by numerous bodily matters, permitting an image of the inside of a person to be formed. This can then be used to see injury to bones and organs or search for foreign objects.
Many different scientists and engineers experimented with X-ray radiation and additional forms of imaging. Wilhelm Conrad Röntgen is often realized as the father of the field, with the German physicist discovering a new form of electromagnetic radiation in 1895. However, Tesla was involved in showing the practicality of X-rays as a diagnostic tool and supported many experiments using X-rays during the late 1890s and early 1900s. He even fashioned his imaging tools that used high voltages and specifically designed tubes.
This study allowed Tesla to be one of the primary individuals to take X-ray images of the human body. Denoting these images as shadowgraphs, they confirmed that it was conceivable to use radiation to observe the inside of a body. He also emphasized some of the hazards of using X-rays, such as the harm they could do to tissue, including burns and substantial pain. These inventions certified that radiology could become what it is today, even though Tesla rarely gets suitable credit.
