Today's topic is 'Integration'. Hard integrations have started after some classes. Writing some maths on the board, the teacher turned around to see if the students were doing math or not. Everyone is doing with their full concentration except one. The teacher came close to him and asked, "Why aren't you doing?". The 14-year-old boy solved every single problem on the board. The teacher thought that the boy must have memorized the answers. The teacher gave some more problems developed on his own. The boy again answered all of them correctly. He didn't even once take the help of a notebook or pen. The teacher realized this boy is really a genius, But we don't know about this genius from our childhood. Tesla, an EEE Engineer who remained ignored in the pages of history, this writing is a tribute to him.


Testa was born on 10 July 1856 in a village in Croatia. His father and grandfather both were priests. He was the fourth among his five siblings. His eldest brother died by falling from a horse. His father wanted Nikola to be a priest like him. His father used to pressurize him for being a priest since his childhood. But Nikola didn't want that. Not at all. Nikola started his primary school in 1861 and learned the German language, maths and religious studies. In 1870, he was reading in high school while this incident of solving integration occurred. It was then that his brilliance was discovered for the first time. In 1873 he completed graduation in three years which would actually take four years.


He returned to his village after graduation the same year. Soon after arriving, he was attacked with cholera. He was in a very critical condition. He was in bed for long nine months. He came very close to death several times. Nikola's father promised him that he would get Nikola admitted to an Engineering School. He won't insist on Nikola for being a priest anymore. Tesla recovered from his sickness. He escaped from being admitted to the military in 1874. He began to wander in mountains. Tesla later said that this close relationship with nature was very important in his life. He used to read Mark Twain.

In 1875 Tesla got admitted to the Austrian Polytechnic. He didn't miss a single lecture in the first year. He got the highest grade in all. His father got a letter from the Dean saying, "Your son is the star of the first class". He continuously struggled from 3 pm to 11 pm. He didn't take any rest in any holiday. In 1879 when his father died, Nikola found a letter that was sent to his father from his teachers saying." Immediately take your son from school or he will die struggling",


In the second year, Nikola had an argument with a professor on "A commentator is needed or not". In the same year, he got addicted to gambling and his scholarship was canceled. In the third year, he spent all his wealth on gambling and became a pauper. But again he earned everything back from gambling. Then he got addicted to playing billiards.


When the exam was knocking at the door, Nikola realized he didn't read a thing. He wanted to increase PL. But his claim was denied. He couldn't graduate. He didn't get even a single grade in his last semester. He became a drop-out.


He went to Slovenia. He used to work there as a draftsman for sixty florins per month. And he used to spend the rest of his time playing cards with people on the roads. In March 1879 his father found him there and insisted he come home. But Nikola didn't go. He was suffering from a nervous breakdown. In the same year, he came home but his father had died by then from a stroke. Tesla started teaching in his old school there.


In 1880, Tesla went to study in Prague at the expense of his uncles. But it was too late. The time of registration was over by then. Besides, the university required to know Greek and Czech languages. He didn't know these languages by then.

In the year 1881, he went to Budapest. He started working in a telegraph company there. Tesla started his first scientific work here, he perfected the telephone amplifier. But he never took any patent for that.


In 1884, he went to work in the company of Thomas Alva Edison. Edison himself hired him. That was in New York. Initially, his work was simple electrical engineering but later on harder problems started to come. He was given the task to redesign the DC generator. In 1885 Tesla claimed that he could make this even better. Edison responded, "If you can do this I will give you 50,000S". After working months after months, Tesla finally succeeded. Then he claimed his payment from Edison. Smiling. Edison replied, "Oh Tesla! you don't understand American humor." Tesla's salary was just increased from 185/week to 28$. This was his prize. But Tesla denied taking it and resigned.


In 1886 he started his own company named "Tesla Electric Light and Manufacturing". There he made "Dynamo Electric Machine Commutator" which was his first patent. But the investors were not interested in the new things of Tesla. Thus he became a pauper. At one time, his parents were gone out of his hands. For the money, he started doing repair jobs. He even engaged himself in digging for 2$. During the winter of 1886/1887, he was thinking, "What profit did I get by studying so much?".


In 1887, Tesla along with two businessmen started a company. For the first time, Tesla used AC to run an induction motor in the lab. Today's electrical world started in that very lab in the hands of Nikola Tesla. He was the first to give the idea of rotating magnetic fields in 1882.


In 1888, Tesla demonstrated AC. Everyone took that as great. He even got an offer of 60,000S. But Edison became anxious. His DC would suffer a huge loss if Tesla's AC would start in the market. Edison named AC as "Death Current". Edison gathered some local boys and paid 25 cents per head for gathering living cats and dogs, Edison electrocuted those cats and dogs along with an elephant and killed them by Tesla's AC to prove that AC is dangerous. But all his efforts went in vain. In 1892 he lost the head post of his own company.


In 1894 Tesla started working for invisible wave. But he didn't take any patent or anything for it. In 1895 Wilhelm Rontgen named that invisible wave as X-ray. Then Tesla told that he had worked with this. In 1895 everything in his lab was destroyed by fire (the loss was worth 50,000S). That's why he couldn't show any work of X-ray. He had to start all over again. When Rontgen was working with X-ray, people thought X-ray had healing powers. But Tesla told these waves are dangerous and let not this be used in the medical field yet. But who listens to him? One Clarence got so much exposed to X-ray that his hand was cut off. Besides Edison himself used an X-ray on him. He repeatedly used an X-ray on his eyes. He almost got blind. In 1903 when he was asked about X-ray he responded, "Beware! don't talk to me about X-ray. 1 am afraid of X-ray".


We know Italian Scientist Marconi is given the credit for inventing the radio. But what we don't know that his works were based on Tesla's work. When Marconi first sent a radio message, Tesla told, "Marconi is a good man. Let him work. He used 17 of my patents".

We know in 1935 Robert Watson Watt invented radar. But in 1917 Tesla gave its theory Question may arise, "Why did he just give a theory? Why didn't he make one himself?" Not at all. He was about to do it. At that time World War-I was going on. He brought this proposal to the US Navy. But do you know who the chief of the US Navy Research and Development during that time was? Edison! He rejected the offer just by seeing the name of Tesla. This technology ended in that very rejection of Edison. Do you know Tesla gave the idea of Hydroelectricity? He told about making practical energy source from Niagara Falls. Nikola Tesla already worked with Cryogenic Engineering 50 years before its establishment. All the materials for making Transistor belonged to Tesla's patent. Today's computer wouldn't have even existed without it. There is a thing called ball lightning. It floats some feet above the ground. This was also shown by Tesla in 1890. Even today's wireless technology is also Tesla's invention. There is an interesting story behind this. In 1898 Tesla ran a boat from a further distance using wireless technology. People didn't even hesitate to claim it as "magic". Tesla wanted to give radio-controlled torpedo to US Navy but they didn't show any interest at that time. Tesla produced artificial lightning. The sound of it was so loud that its sound was heard from 15 miles away Colorado-135 feet long million-volt of lightning. Horses were running about. Butterflies were electrified and bluish light was glowing around them. Tesla claimed he could make an earthquake strong enough to destroy whole mankind even slice the earth into two pieces. In 1928 Tesla made a plane that could take off vertically. This was his last patent. Do you know what was the last work of Tesla? To build a tower by which people would get free wireless energy. His dream was one day the whole world will get free energy. But after building the tower, when the builder came to know there is no financial profit for him in this, he shut it down. Full budget loss!

Tesla could talk in eight languages. Serbian, English, German, Czech, French, Hungarian, Italian, and Latin. Marconi got the Nobel prize but Tesla never got. Good news! Even Edison didn't get it! Nikola Tesla's hobby in his last days was to feed pigeons. Once while feeding the pigeons Tesla had an accident. He got hit by a taxi and his three ribs broken. This happened while he was staying at the hotel New Yorker. Tesla didn't consult any doctor his whole life. This was his stubbornness. Even this time he didn't consult any doctor. So actually what really happened to him, we don't know for sure. Tesla didn't even want to know who hit him. He just called a cab and went to the hotel. He was in bed for months. His grief was he couldn't feed the pigeons. In 1938 spring. Tesla started to walk again. In this very hotel-room no. 3327, on 7 January 1943 died this so-called "mad scientist.". He hanged " DO NOT DISTURB" sign on his door two days prior to his death. Avoiding that sign maid Alice went in and discovered his dead body. The cause of his death was Coronary thrombosis. Two days after his death, the FBI took over all his properties. An MIT professor checked all his research materials. The professor reported that there was nothing dangerous.

Tesla died being poor and in debt. He spent his last days drinking milk and eating Nabisco biscuit in that hotel. In an interview in his final days, he told that an injured pigeon always came to visit him. He spent 2000$ to make a machine for healing that pigeon. Slowly the wings and bones of the pigeon were healed. He remained unmarried for his whole life. No intimacy with any woman was seen with Tesla. He thought this would harm his work. On the other hand, so many women were mad for him. What didn't they do! But he didn't pay any heed to them. He told, "I do not think you can name many great inventions that have been made by married men". Very few people on earth have a photographic memory. Tesla was one of them. He could fully read a book from his memory. He could memorize thousands of designs. Never did he wrote with hands or draw. He used to do everything from memory. Which dimension would be how much, he could solve in his memory.


Nikola Tesla was the vice president of IEEE (it was AIEEE then) from 1892 to 1894. During his middle age, he became friends with Mark Twain. He spent a lot of time with him. Mark was pleased to see his induction motor. In 1931 when Edison died, among hundreds of conciliation in the New York Times newspaper, the only criticism was from Tesla. He fulfilled the rage of his whole life there.

Tesla never slept more than two hours. But sometimes he used to snooze. In his words, this was to "recharge his batteries". While in school he played Billiards continuously for

48 hours. Once he came out of the lab after working for 84 hours continuously. Nothing happened to him. In his honor, the SI unit of magnetic flux intensity is named 'Tesla'.

The 10th of July is Tesla day. Everyone remembers Einstein, Edison but who remembers
Tesla! He is a legend born at the wrong time.
