The Iranian mathematician in 2014 became the first, and to date, the only woman as well as the first Iranian to be awarded the Fields Medal (often referred to as the mathematical equivalent of the Nobel Prize). The citation for her award recognized βher outstanding contributions to the dynamics and geometry of Riemann surfaces and their moduli spaces.β
While a teenager, Mirzakhani won gold medals in the 1994 and 1995 International Mathematical Olympiads for high-school students, attaining a perfect score in 1995. In her professional life, her research topics included TeichmΓΌller theory, hyperbolic geometry, ergodic theory, and symplectic geometry.
She died of Breast Cancer on 14 July 2017 at the age of 40. Upon her death, several Iranian newspapers broke taboo and published photographs of Mirzakhani with her hair uncovered, a gesture that was widely noted in the press and on social media.
Maryam Mirzakhaniβs birthday, 12 May, is celebrated as International Women in Mathematics Day.

By 1894 he conducted experiments in India to determine the validity of the hypothesis of Alphonse Laveran and Patrick Manson that mosquitoes spread the disease.
In later work, in West Africa, he also determined the mosquito species carrying the deadly African fever. During this active career, Rossβ interest lay mainly in the initiation of measures for the prevention of malaria in different countries of the world. He carried out surveys and initiated schemes in many places, including West Africa, the Suez Canal zone, Greece, Mauritius, Cyprus, and in the areas affected by the 1914-1918 war.

He was Polish surgeon whose innovations in operative technique for a wide variety of diseases helped develop modern surgery. Jan contributed prodigiously to cancer surgery, especially on organs of the digestive system. He was first to suture a perforated gastric ulcer (1885), surgically restore part of the oesophagus (1886), remove a malignant part of the colon (1903), and describe what is now known as Mikuliczβ disease. In 1881 he developed improved models of the oesophagoscope and gastroscope. As an ardent advocate of antiseptics, he did much to popularize Joseph Listerβs antiseptic methods. He used a gauze mask and was one of the first to use gloves during surgery.
Fluent in Polish, German, Russian and English.

There was a common story among farmers that if a person contracted the relatively mild and harmless disease of cattle called cowpox, immunity to smallpox would result. On 14 May 1796 Jenner removed the fluid of a cowpox from dairymaid Sarah Nelmes, and inoculated James Phipps, an eight-year-old boy, who soon came down with cowpox. Six weeks later, he inoculated the boy with smallpox. The boy remained healthy, proving the theory. He called his method vaccination, using the Latin word βvaccaβ, meaning cow, and βvacciniaβ, meaning cowpox. π±πππππ ππππ ππππππ ππππ πππ ππππ πππππ.
