Intelligence along with street smarts is what is needed in today’s world. Intelligence Quotient (IQ) is a measure, a score obtained from a test, measuring a person’s intelligence or how sharp their brain works. These tests are for certain areas like language fluency, 3 dimensional thinking, etc.

IQ scores are used as predictors of educational achievement, special needs, job performance and income. The average IQ of the population is 100 as many score between 70 and 130.

World’s 10 highest IQ holders are:

10. Stephen Hawking (IQ 160)

Stephen William Hawking was born on 8^{th} January, 1942 in United Kingdom. His IQ is 160. He is devoted to the core fields of science and have worked on gravitational theorems in the framework of general relativity, and many theoretical predictions on black holes stating that they emit radiations and known as hawking radiation. He attended Oxford University in 1959 when he was only 17 years old.

He was the first to explain the cosmology thesis by a union of the general theory of relativity and quantum mechanics. He is a vocal supporter of the many-worlds interpretation of quantum mechanics.

Stephen is a fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and a recipient of the Presidential Medal of Freedom – the highest civilian award in the United States. He was also a professor of Mathematics at the University of Cambridge between 1979 and 2009.

9. Albert Einstein (IQ 160-190)

He was born on 14^{th} march 1879 in Germany. His IQ was estimated between 160 and 190. The right handed physicist did his schooling from Germany. His devotion towards science started with a compass that his father showed him. What made him work was reason behind what makes a compass needle move. Apart from physics, he had a keen interest in mechanics and mathematics. He also applied for polytechnic colleges in Italy, but due insufficient grades he failed to get admission. On the advice of the dean of the same, as he had exceptionally high grades in physics and mathematics, he completed his secondary education from Switzerland.

He worked in the field of Quantum theory and was the one to develop the general theory of relativity which was the turning point in the field of science. He is also very well known for his mass–energy equivalence formula E = mc^{2}. For his services to theoretical physics, and for his discovery of the law of the photoelectric effect, he was awarded with a Nobel Prize. He continued to work in the field of Quantum theory even after his photoelectric effect thesis.

At an age of 76, he died on 17^{th} April, 1955 due to some internal bleeding.
