Problem: Tu Youyou (Chinese: Tu You You ; pinyin: Tu Youyou; born 30 December 1930) is a Chinese pharmaceutical chemist and educator. She is best known for discovering artemisinin (also known as qinghaosu) and dihydroartemisinin, used to treat malaria, which has saved millions of lives.

Tu Youyou was born in Ningbo, Zhejiang, China on 30 December 1930. She attended Xiaoshi Middle School for junior high school and the first year of high school, before transferring to Ningbo Middle School in 1948. From 1951 to 1955, she attended Peking University Medical School / Beijing Medical College. Tu studied at the Department of Pharmaceutical Sciences, and graduated in 1955. Later Tu was trained for two and a half years in traditional Chinese medicine.  After graduation, Tu worked at the Academy of Traditional Chinese Medicine (now the China Academy of Traditional Chinese Medical Sciences) in Beijing. She was promoted to a Researcher (Yan Jiu Yuan , the highest researcher rank in mainland China equivalent to the academic rank of a full professor) in 1980 shortly after the Chinese economic reform began in 1978. In 2001 she was promoted to academic advisor for doctoral candidates. Currently she is the Chief Scientist in the Academy.  As of 2007, her office is in an old apartment building in Dongcheng District, Beijing.  Before 2011, Tu Youyou had been obscure for decades, and is described as "almost completely forgotten by people".  Tu is regarded as the Professor of Three Noes - no postgraduate degree (there was no postgraduate education then in China), no study or research experience abroad, and not a member of any Chinese national academies, i.e. Chinese Academy of Sciences and Chinese Academy of Engineering. Up until 1979, there were no postgraduate degree programs in China, and China was largely isolated from the rest of the world. Tu is now regarded as a representative figure of the first generation of Chinese medical workers since the establishment of the People's Republic of China in 1949.

Question:
Howard was born in Atlanta, to Dwight Sr. and Sheryl Howard, and into a family with strong athletic connections. His father is a Georgia State Trooper and serves as Athletic Director of Southwest Atlanta Christian Academy, a private academy with one of the best high school basketball programs in the country, while his mother played on the inaugural women's basketball team at Morris Brown College. Howard's mother had seven miscarriages before he was born. A devout Christian since his youth, Howard became serious about basketball around the age of nine; when in the eighth grade, he resolved to be selected as the number one pick in the NBA Draft one day.
Standing at 6 feet 11 inches tall (2.11 m) and weighing 265 pounds (120 kg), Howard plays the center position. Howard led the NBA in rebounding from 2007 to 2010, and again from 2012 to 2013. Howard's rebounding is in part facilitated by his extraordinary athleticism; his running vertical leap was tested at 39.5 inches in 2011, rare for a player of his size. He demonstrated this skill in the 2007 Slam Dunk Contest, where he completed an alley oop dunk from teammate Jameer Nelson while slapping a sticker onto the backboard at 12 ft 6 in (3.81 m) high. The sticker showed an image of his own smiling face with a handwritten "All things through Christ Phil: 4:13", a paraphrase of Philippians 4:13. Howard's leaping reach of 12 ft 6 in (3.81 m) is the highest documented in NBA history, 1 inch (2.5 cm) higher than Shaquille O'Neal's previous record of 12 ft 5 in (3.78 m). As of April 2013, Howard's career average of 12.9 rebounds per game (in the regular season) ranked 12th in NBA history.  Howard's abilities and powerful physique have drawn attention from fellow NBA All-Stars. Tim Duncan once remarked in 2007: "[Howard] is so developed... He has so much promise and I am glad that I will be out of the league when he is peaking." Kevin Garnett echoed those sentiments: "[Howard] is a freak of nature, man... I was nowhere near that physically talented. I wasn't that gifted, as far as body and physical presence." Subsequent to a game in the 2009 NBA Playoffs, Philadelphia 76ers swingman Andre Iguodala said: "It's like he can guard two guys at once. He can guard his guy and the guy coming off the pick-and-roll, which is almost impossible to do... If he gets any more athletic or jumps any higher, they're going to have to change the rules." As early as December 2007, ESPN writer David Thorpe declared Howard to be the most dominant center in the NBA.  While many sports pundits have been rating Howard as one of the top young prospects in the NBA since 2006, Howard has some weaknesses in his game. Offensively, his shooting range remains limited; he is also mistake-prone, having led the NBA in total number of turnovers in the 2006-07 season. Like many centers, he has a low free throw conversion percentage. As a result, he is often a target of the Hack-a-Shaq defense and is annually among the league leaders in free throw attempts. During the 2007-08 regular season, Howard led the NBA with 897 free throw attempts while shooting only 59% from the free throw line. Also in that season, outside of layups and dunks, his shooting percentage was only 31.6%. In the 2008-09 season, he led the NBA again with 849 free throw attempts and in 2009-10, he was second in the NBA with 816.
