Her skills were so notable, that she became the leader of the Neoplatonism movement in Alexandria around 400. Her reputation led students from all around the world to come visit here. She was recognized as a better philosopher than most of the men during her time. Hypatia gave lectures at her house and in lecture halls. She lectured on astronomy, mathematics, philosophy, and religious literature. She wrote a number of books about mathematics.
Synesius of Cyrene was a student of Hypatia. His letters provided some of the most important information on her life and her teachings. She taught Synesius about the building of an astrolabe.
Hypatia was never married because she said she was “wedded to the truth”. She was an acquaintance of Orestes. He was the pagan governor of Alexandria. Radical monks murdered her. They possibly murdered her because the pagans seemed to have caused enmity among this Christian town. They persecuted her, and scattered her body parts around the city. She died at 45 years old, in 415 C.E.
Ada Yonath
Ada E. Yonath, Hebrew: עדה יונת , (born June 22, 1939) is an Israeli crystallographer. She received the 2009 Nobel Prize in Chemistry together with Thomas A. Steitz and Venkatraman Ramakrishnan for studies of the structure and function of the ribosome.
She was born in the Geula quarter of Jerusalem. Her father was a rabbi. Yonath and her family moved to Tel Aviv after her father died.
She received her bachelor's degree in chemistry in 1962. She received her master's degree in biochemistry in 1964. She got both degrees from the Hebrew University in Jerusalem. She received her Ph.D. in X-Ray Crystallography at the Weizmann Institute of Science in 1968. Yonath made the first protein crystallography lab at the Weizmann Institute. Her work showed the function of ribosomes. Yonath worked at Carnegie-Mellon University and MIT for several years. She stayed as Weizmann Institute for the rest of her career.
Ada Yonath is an Israeli chemist who made pictures of ribosomes using X-ray Crystallography. Ribosomes are the part of cells in the human body that put together proteins. X-ray Crystallography makes pictures of molecules by bunching them into crystals. This method is only used to make models of single atoms. Yonath used this methods to crystallize ribosomes although they are made of many atoms and proteins. This made her work very difficult. She returned to the Weizmann Institute of Science in 1970. She started the first Protein Crystallography lab in Israel. She did research at the Max Planck Institute for Molecular Genetics in Berlin, Germany from 1979 to 1984. She began trying to make ribosomes into crystals in 1970.  [1]
She made the first model of a large ribosome in 1980.
In 2006 she won the Wolf Prize in Chemistry.
She won the 2009 Nobel Prize in Chemistry with Venkatraman Ramakrishnan and Thomas Steitz. This Nobel prize was for her work in making images of ribosomes. She studied Molecular Genetics in Berlin, Germany, before winning the Nobel prize.
Yonath led a research team at the Max Planck Institute in Hamburg, Germany for 18 years. She also continued research at the Weizmann Institute of Science.
Youyou Tu
Youyou Tu (born 30 December 1930) is a Chinese pharmacologist. She won the Nobel Prize in 2015 for medicine. She is famous for making a medicine to treat Malaria. Malaria is a sickness or disease. It is spread by mosquitoes. It poorly affects a lot of people in the world. Many people have died from Malaria. Tu came up with a cure.
Tu was born on December 30, 1930.  She was born and raised in Ningbo, Zhejiang. Zhejiang is a province of China. It is located in eastern China. In 1951, she moved to Beijing. She went to the Peking University in Beijing. At the university, she studied pharmacology. In 1955, she finished college and started working at the China Academy of Traditional Chinese Medicine in Beijing. It is now called the China Academy of Chinese Medical Sciences.
In 1969, China was having a cultural revolution against Western ideas. This means that many schools, colleges, and research centers were closed. Tu was assigned to a secret project that was to find the cure for Malaria during this time. Malaria was killing American and Vietnamese soldiers in Vietnam before the treatment was found. She studied traditional Chinese medicinal ancient text. She was trying to find an herbal treatment. The text they read gave information about a medicinal plant, Qinghao. Qinghao is also known as sweet wormwood. Tu and two other scientists found a part of the plant that helped treat Malaria. This was made into a drug that stopped and treated the disease in millions of people. This drug was called artemisinin.
Rosalyn Yalow
Rosalyn Yalow (July 19, 1921 May 30, 2011) was an American medical physicist.
Yalow was born on July 19, 1921 in the Bronx, New York City. She graduated from Hunter College in 1941. She also went to a all-female college in New York called Hunter College. Yalow was Jewish. This made it difficult to become a scientist, due to prejudice. She continued trying. Yalow got a PhD from the University of Illinois at Urbana-Champaign.
Yalow became a consultant in nuclear physics at the Bronx Veteran’s Administration Hospital in 1947. She was assistant chief of radioisotope service in 1950. She was made a research professor at the Sinai School of Medicine in New York City in 1968. In 1973, she was made head of Solomon A. Berson Research Laboratory at the Bronx Veteran’s Administration Hospital.
Yalow won the Nobel Prize in Physiology or Medicine in 1977. She was the second woman to win that prize. She shared the award with Roger Guillemin and Andrew Schally.
Yalow was known for the creation of the radioimmunoassay (RIA). The RIA labeled things in the blood with radioactive marks. Yalow and Solomon Berson first used the RIA in 1959. It was first used to study the insulin in blood of diuabetics ( people with diabetes). This was an advancement that helped many people with diabetes.
Maryam Mirzakhani
Maryam Mirzakhani (May 3, 1977 – July 14, 2017) was an Iranian mathematician.
She worked at Stanford University. Her research topics include Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry.
On 13 August 2014, Mirzakhani became both the first woman and the first Iranian honored with the Fields Medal, the most prestigious award in mathematics.
Mirzakhani was born in May 1977 in Tehran, Iran. She enjoyed math and puzzles in high school. She earned her bachelor’s degree at the Sharif University of Technology in Tehran. Mirzakhani then went to Harvard to earn a Ph.D. in 2004.
In high school, Mirzakhani found her talents in math. She decided to reconsider her career goals. This was made possible by her principal. Her principal tried to give women the same chances as men to succeed.
Mirzakhani was also given extra math assignments, which gave her access to university laboratories. She was also allowed to study by herself in the library. This privilege was only given to a few people.
Mirzakhani was diagnosed with breast cancer in 2013. She died of the cancer on July 14, 2017 in Palo Alto, California, aged 40.
Mirzakhani won the Fields Medal award, the highest mathematical award, in 2014 for her accomplishments in math. She won this award because of her work on Riemann surfaces, a complex mathematical subject. Her work on this subject has improved the basics of both mathematics and physics.
Mirzakhani proved multiple relationships between "moduli" spaces, classes of Riemann surface structures. Her talent led her to be selected twice for the Math Olympiad Team.
Girls had never been part of the Iranian Math Olympiad team. Mirzakhani was the first woman to be on the team and was selected two times in a row. She won gold medals for her team. In 1994, she only had one point taken off and in 1995, she had a perfect score. This was a big accomplishment since she was the first Iranian to do so.
