This Korean super-genius was born in 1962 and might just be the smartest guy alive today (he's recognized by the Guinness Book of World Records as having the highest IQ of anyone on the planet).
By the age of four he was already able to read in Japanese, Korean, German, and English. By the age of five he solved complicated differential and integral calculus problems. Later, on Japanese television, he demonstrated his proficiency in Chinese, Spanish, Vietnamese, Tagalog, German, English, Japanese, and Korean. Kim was listed in the Guinness Book of World Records under "Highest IQ"; the book estimated the boy's score at over 210.
Kim was a guest student of physics at Hanyang University from the age of 3 until he was 6. At the age of 7 he was invited to America by NASA. He finished his university studies, eventually getting a Ph.D. in physics at Colorado State University before he was 15.
In 1974, during his university studies, he began his research work at NASA and continued this work until his return to Korea in 1978 where he decided to switch from physics to civil engineering and eventually received a doctorate in that field. Kim was offered the chance to study at the most prestigious universities in Korea, but instead chose to attend a provincial university. As of 2007 he also serves as adjunct faculty at Chungbuk National University.
