How can someone measure genius? There are several tests and indicators, but even then there is no clear line that can describe people who excel and make a difference in different fields with no similarities between them. The website thebestschools.org, undertook the difficult task of creating a list of the “50 Greatest Living Geniuses.” The list includes names such as Stephen Hawking, in the field of physics, Oprah Winfrey, in the field of media, Jackie Chan for his knowledge in martial arts and Greek physician and psychiatrist Evangelos Katsioulis for his contribution in the field of medicine. Evangelos Katsiouls has one of the highest IQs ever recorded, standing at 205 on the Stanford-Binet scale. He graduated from the Aristotle University of Thessaloniki Medical School in 2000, and then did his postgraduate studies in Medical Informatics (2001-2003) and Philosophy (2008-2013) at the same university. He also did his PhD at AUTH, specializing in Psychopharmacology (2009-2013). Katsioulis has excelled in every area that he gets involved with, including oncology and neurology, while he has also ventured into psychiatry and psychopharmacology, contributing particularly in the research for antipsychotic drugs. Katsioulis is a member, and founder of various numerous high-IQ societies and organizations. Thebestschools.org has chosen people who have the ability to change their time and place through their work. The 50 geniuses were listed in alphabetical order, since it was impossible to compare the intelligence of two people, especially if they work in completely different fields.
