Nikola Tesla’s revolutionary inventions
Once, Einstein was asked how it feels being the smartest man on the planet. His answer was: “I don’t know. You should ask Nikola Tesla”.
Throughout its development, the mankind has had both magic moments and negative moments. All those negative moments had unexpectedly long consequences, most of them being a part of our today’s life. Those magical moments, instead, although as many as the negative ones, didn’t have any consequences at all. Have you ever wondered, while working with a certain machine, who was the genius who invented it?
But humanity’s magical moments are infinitely more. Starting with the discovery of stone sharpening, of making a fire, melting the first metals, creating the first arc, the first wheel, the first robot in history, namely the trap, all were magical moments. The whole history of mankind is strewn from place to place and from time to time by the birth of people whose thinking and work were significantly above their time; birth of geniuses in moments of genius.
The mankind was blessed with people like Hermes Trismegistus, Thales of Miletus, Herodotus, Pythagoras, Hippocrates, Heron, Plato, Guttenberg, Leonardo da Vinci, Nicolaus Copernicus, Tyco Brahe, Roger Bacon, Galileo Galilei, René Descartes, Blaise Pascal – to name just a few representatives of Antiquity and the Middle Ages.
These people were many, and in modern times, even more than in other historical periods. Each one of them has provided great opportunities to the whole humanity. But most of the times, humankind not only didn’t know or didn’t want to take advantage of them, but also dealt infamous with them, even going to their abolition.
But the worst thing is that, even today, mankind still has the same attitude towards these people. But don’t be surprised. It’s in our nature. We’ve always been scared by what we didn’t understand. However, recently, this attitude of fear has been replaced by an infinitely more harmful attitude: small groups of interest have appropriated, at the expense of the rest of humanity, the opportunities that these geniuses had offered. Concerning these geniuses, the outcome is still the same: discredit, carried to decay.
Like all the other centuries before, the twentieth century has its astral hours. In this century, one name stands out: Nikola Tesla, an Istro-Romanian engineer of genius born on July 10, 1856 in Smiljan, Gospici village, in the former Yugoslavia, who died poor and unknown, in a hotel room in New York on January 7, 1943. Tesla is the one who propelled humanity into the electrical age.
You never heard of him at school, although 90% of today’s electrical civilization is owed to him. Have you heard of Edison, Marconi, Roentgen, but you didn’t know they shamelessly stole and used his inventions. To convince yourselves, go into any library and look for his name in history of science books, physics books, engineering books and so on, that have been published to date.
Why he died poor, since the current civilization would not have been the same without him and why his name doesn’t appear in physics textbooks of the world? Because Tesla has never agreed that his inventions become the preserve of an oligarchy or military power. Because, discovering that electricity is ubiquitous, in unlimited quantities and can propel all the cars in the world without using oil, coal, methane gas or any fuel, he never accepted the idea that the oligarchs would have possess it and sell it to population.
When you think of electricity, you think of Edison, when you think of radio, you think of Marconi. In fact, there’s only one genius of electricity, a man who dreamed to give mankind inexhaustible energy – Nikola Tesla. He is the one who made possible the transmission of electrical energy worldwide, through his inventions. The fact that this brilliant inventor was Romanian is a less known detail. During his lifetime, other people were praised instead. Others have been appreciated, but the history will fix things.
It’s no exaggeration to say that Nikola Tesla has transformed the world due to electricity. The extraordinary heritage he has left to the humanity can be seen everywhere the electromagnetism is used. His name is linked to the famous Philadelphia experiment and also the first contact with other civilizations, the scientist receiving a repeated radio signal from space.
Besides discoveries in electromagnetism (single and polyphase alternating current, engines of all kinds, high frequency and high voltage technologies, so on) and engineering discoveries, Tesla is considered a pioneer in mechanics (Tesla turbine), robotics, ballistics, computers, nuclear physics and theoretical physics. Yet, inexplicably, history seems to have forgotten this remarkable man who has given humanity so many inventions.
The brilliant scientist was inventor, physicist, mechanical engineer and electrical engineer. Nikola Tesla’s inventions and theoretical research are underlying modern knowledge about the power of electricity, alternative current systems, including polyphasic systems, power distribution systems and the AC motor, which determined the “second industrial revolution”. One of his most important inventions is the AC generator, based on which the hydropower near Niagara Falls works.
We also owe Tesla the first wireless communications system, the first robots, the first transmitter, the idea of vertical takeoff vehicle and more. Tesla proposed a scheme similar to a science fiction: a global wireless communication system to deliver telephone messages across the ocean, news, music, stock market reports, private messages; secure military communications in any corner of the world. “When wireless communication will be widely applied, the earth will turn into a huge brain, able to respond in any part of its”, Tesla said.
Nikola Tesla is considered by American biographers as a Serbian emigrant (like other famous Romanians, such as Henri Coanda or George Enescu, Tesla also received a loan nationality). Actually, he was an Istro-Romanian. He was born on the night of July 10, 1856, as a son of an Orthodox priest, Milutin Teslea, and Gica Mandici. His father was descended from an anti Ottoman border guards family, in the former Austro-Hungarian Empire. The originally last name was Draghici, but was replaced by the nickname Tesla, according to the family practiced profession, that of carpenter (craftsmen).
Nikola Tesla had a fascinating life. Due to his exceptional native vitality, he defeated some serious health problems, although the doctors were saying there’s no recovery. And at the age of 60, he felt younger than ever. Since he was a child, he had extrasensory perceptions. Different images, often accompanied by strong flashes, were disturbing his vision, interfering with his thoughts. At that time, he had no idea how important these perceptions will be in his later discoveries. Tesla had the ability to perceive, in front of his very eyes, an object designated by a spoken word that sometimes it was impossible to figure out if what he was seeing was real or dreamed.
As time passed by, Tesla has developed the ability of making astral projections. Thus, his greatest pleasure was to travel his astral body in the subtle worlds, visiting wonderful unsuspected places in the astral plane. He was constantly concerned about these perceptions until age 17, when he got the idea to capitalize and fructify all the information from these incursions.
Due to his exceptional view, he could mentally build, test and disassemble any device, without building models, drawing projects or making new experiences. Tesla used to make his inventions in his mind, until the final stage. He had an idea, crystallizing it in mind, doing necessary adaptations and improvements and he was switching the appliance on in mind, until everything was perfect. Finally, he actually built it and the invention practically worked as he had been visualising it.
Nikola Tesla went down in history by inventing the alternating current, modern engines and AC generators and… stupor!… fluorescent tubes. His name is linked to magnetic induction, which is measured in “Tesla”. Tesla Coil is even today a very well kept secret of high voltage engineering. Invented in 1891, this coil is a transformer that is powered from the network or from batteries and raises the voltage to hundreds of thousands of volts, thus obtaining high frequency current.
Taking the example of a swing, if we push it out of step with current momentum, it will oscillate increasingly slower. But if we give the swing impulses just at the end of a cycle, thus achieving a synchronization using exactly the right time, this will lead to a gradual increase amplitude of its oscillations. We can call this synchronization putting into resonance.
In those circumstances, oscillations can achieve amazing values. In ideal functioning, the impulse triggers at the end of each cycle, exactly at the right time. In this ideal state of resonance, the power gain is gigantic. Thus, the Tesla coil can be used for artificial lighting, for water disinfection, as a radio transformer, electricity transformer, as well as in global communications, high frequency currents electrotherapy, to generate X-rays or as a disinfection ozone generator, without excessive energy consumption. The discovery of tachyon energy is also due to Tesla’s research.
Beyond this, the greatest merit of Tesla is his pioneering work in the field of free energy. Revealing the secret of free energy generation would soon collapse most industries currently existing on the planet who earn huge sums from their taxpayers. This is the main reason why Tesla’s research, which should belong to all mankind, are kept secret.
On the technology of the future
“Soon, we’ll be able to send wireless messages all over the world so simply that any individual can carry and operate his own aparatus.”
On contemporary scientists
“Today’s scientists have substituted mathematics for experiments, and they compose equation after equation, and eventually build a structure which has nothing to do with reality.”
On patience and planning
“That’s the problem with many inventors; they lack patience. They lack the willingness to work a thing in their mind, slowly, clearly and sharply, so that they can actually understand how it will work. They want to try their first idea right off; and they lose lots of money and lots of good material, only to find eventually that they are working in the wrong direction. We all make mistakes, and it is better to make them before we begin.”
On individualism and mankind
“We speak of man, but we don’t imagine mankind as a whole. To apply scientific methods to a particular person, we must think of humanity too. But can anyone doubt that all the millions of individuals and infinite types of characters constitute an entity, a unit? Despite freedom of will and action, we are held together as stars in the sky, united by indestructible ties. These ties are invisible, but we can feel them. I cut my finger and it bleeds, as this finger is part of me. I see a friend hurt, in pain, and it hurts me, too; my friend and I are a whole. Even if I see an enemy in pain, an enemy I care least for, it still grieves me. Does this not prove that each of us is a part of a whole?”
“We build to distroy. Most of our work and resource is wasted. Our progress is marked by devastation. Everywhere is just a appalling waste of time, effort and life. Yes, it’s a sad view, but true.”
On human being
“Each individual should consider his body a priceless gift, from those who love him above all, an indescribable beauty, a masterpiece. The mystery that lies hidden in the conception of the human being is so delicate that even a word, a breath, a look, even a thought can affect it. The cutter that spreads disease and death is not only self-destructive, but also immoral.”
On human nature
“Our virtues and defects are inseparable, like energy and matter. When they separate, man is no more.”
On inventor’s psychology
“I don’t think there’s a greater happiness that can fill a man’s heart such as that felt by the inventor who sees a creation of his mind becoming reality. Such emotion can make an individual forget about food, sleep, friends, love… everything.”
On his legacy
“I invested all my money in experiments to make new things, allowing mankind to live easier. What will be the result of my research, only the time will tell. But whatever they may be, and to whatever this principle may lead, I’ll be more than satisfied if the future generations will accept that I have contributed, even in small part, to the advancement of science.”
On others that took credit for his inventions
“Let the future tell the truth and appreciate each one according to his work and accomplishments. The present is theirs. The future, for which I worked, is mine.”
