Among them, about 1000 was invented before he invented it, and several of them had more accurate formulas before him. For example, now someone writes that I invented calculus. Who knows whether you invented it independently or copied it from Leibniz?
So this 1000 is a re-invention and meaningless. There are many repeated inventions, such as π formula, and he invented more than a dozen.
There are still some mistakes, but the error is not big. We will slowly correct it with the development of time, but the principle is correct. So these formulas are similar to how we feel about black-and-white TV sets now. Our TV has evolved four or five times than black and white TV. But the principle is the same.
For example, in his pi formula, if k is 1000, then it is only accurate to 1500. Do we all have 654.38+050 billion bits now?
There are also some meaningless formulas.
But I can't stand his abundance, some of which have been proved to be correct.
Generally speaking, Lamanukin is a genius, but his achievements are too biased and he only aims at one direction; The second is that many formulas have problems and uneven quality, and they can probably rank in the top 30 among mathematicians.
Adult work:
When he came of age in India, he had to find a job because he got married. With his mathematical calculation ability, he looked for a job as a scribe everywhere in Chennai (formerly known as Madras). Finally, he got a job and contacted researchers in Cambridge at the suggestion of an Englishman.
As an employee of Chennai's chief accounting firm, Lamanukin hopes to devote himself to mathematics without doing other work. He appealed to influential Indians for support, and published some papers in Indian mathematical magazines, but failed to find financial support. At this time, Sir AshutoshMukherjee is trying to support his cause.
