If you want to know who the smartest person in the world is, look no more. Here is a list of 10 people who have the highest IQ scores today.

The brain is the most mysterious part of the human body. It is an essential part of our system. Although each individual possesses special qualities that define their intelligence, some of us simply stand out of the crowd. So it makes sense why we want to know who the smartest person in the world is and what they have done.

Let’s take a look at people with the highest IQ ever recorded:

10. Stephen Hawking

Stephen Hawking is a scientist, a theoretical physicist and a cosmologist who managed to amaze us all with the IQ level of 160. He was born in Oxford, England, and has proven to be the smartest person in the world many times. He is currently experiencing a paralysis, but nevertheless, the level of his IQ has made him overcome this handicap. Moreover, his contribution to Science and Cosmology is unparalleled.

9. Andrew Wiles

Sir Andre John Wiles is a British mathematician and professor of research at the Royal Society of Oxford University. He specializes in number theory and has an IQ level of 170. One of his many successes has been the demonstration of Fermat’s theorem.

8. Paul Gardner Allen

Paul Gardner Allen is an American businessman, tycoon, investor and philanthropist, well-known as the co-founder of the Microsoft Corporation along with Bill Gates. In June 2017, he was named to be the 46th richest person in the world, with an estimated net worth of $20.7 billion.

As opposed to the common outdoor activities that teenagers usually enjoy, Paul Garner Allen and Bill Gates in their teenage years would go dumpster diving for computer program codes.

7. Judit Polgar

Born in Hungary in 1976, Judit Polgár is a chess master. She is by far the most powerful female chess player in history. In 1991, Polgár obtained the title of Master at the age of 15 and 4 months, being the youngest person ever since.

5. Rick Rosner

3. Christopher Hirata

Since 1986, she has been writing for “Ask Marilyn” and “Parade” magazines where she solves puzzles and answers questions on various topics.

1. Terence Tao

Terence Tao is an Australian mathematician working in harmonic analysis, partial derivative equations, additive combinatorial, Ramsey ergodic theory, random matrix theory, and analytical theory. Tao exhibited extraordinary mathematical abilities from an early age, attending university-level mathematics courses at the age of 9.

He and Lenhard Ng are the only two children in the history of the Johns Hopkins’ Study of Exceptional Talent program to have achieved a score of 700 or greater on the SAT math section while being just nine years old.

Tao carries a level of intelligence of 230 and is the smartest person in the world today. He has received inspirational prizes, such as the BöCHER Memorial Prize in 2002 and the Salem Prize in 2000.

Additionally, Tao was a co-recipient of the 2006 Fields Medal and the 2014 Breakthrough Prize in Mathematics. These are just a few of the many. He is also the youngest professor at UCLA.

Now you know who the smartest person in the world is. Amazing, isn’t it? Yet, we should not be discouraged. There is a genius inside every one of us!

    Why is Judit Polgar the most powerful female chest player in the world. And then Garry Kasparov said to be the best chess player of all time and was # 1 at some point but Judit Polgar beat him at chess? Why is she the most powerful female instead of her true accomplishments as a chess player?

    This shows you have no idea what IQ is really about Andreea. I once spoke with Marylin and she’s not really that wise. I am also a candidate for Mensa but I rejected it as it is not what its cracked up to be. High IQ is only a subjective number with nothing to reference it to in the real world. Just because some random Asian kid has an eidetic memory for spelling, remembering numbers, and memorized math formulas does not make him a genius. Have him use an eclectic set of skills like Issac Newton to solve the problems of Earth and then I’ll take notice.

    Smartness is not IQ score, but creativity plus photographic memory can be said to be samrtness.
