Marie Skłodowska Curie was born 7 November 1867 and she died 4 July 1934. She was a She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her older sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. She shared the 1903 Nobel Prize in Physics with her husband Pierre Curie and with physicist Henri Becquerel. She won the 1911 Nobel Prize in Chemistry.

Her achievements included the development of the theory of radioactivity (a term that she coined, techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world's first studies into the treatment of neoplasms were conducted using radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. During World War I, she developed mobile radiography units to provide X-ray services to field hospitals.

While a French citizen, Marie Skłodowska Curie, who used both surnames, never lost her sense of Polish identity. She taught her daughters the Polish language and took them on visits to Poland.She named the first chemical element that she discovered‍—‌polonium, which she isolated in 1898‍—‌after her native country.

Marie Curie died in 1934, aged 66, at a sanatorium in Sancellemoz (Haute-Savoie), France, of aplastic anemia from exposure to radiation in the course of her scientific research and in the course of her radiological work at field hospitals during World War I

Anna Maria Sibylla Merian –born April 2nd 1647 in Frankfurt, as a descendant of the Merian family. She was a German naturalist,  entymologist and illustrator. She is still considered one of the best botanical artists in the history.

Her journey with scientific illustration started when her stepfather, Jacob Marrel, started teaching her painting and drawing. In the beginning she painted the insects she caught in the garden. Merian married her stepfather’s apprentice, Johann Andreas Graff and after the first child they moved to his hometown – Nuremberg. She also taught painting, taking the unmarried daughter from wealthy families as her students. It helped the family to climb higher in the social standing.

In 1654 she published her first book – New Book of Flowers.

In 1677 her illustrations of the butterfly’s transformations were published, alongside the illustrations of numerous plants.

In 1685 Merian goes to live in celibacy in the religious commune (the Labadists, protestants). She takes her mother and two daughters –Johanna Helen and Dorothea Maria - with her. Her husband is not so thrilled about the idea and leaves to never come back there.

She lived in home owned by the first governor of Surinam, who encouraged her to continue her studies. Thanks to the relation she begins her studies of flora and fauna of Surinam and South America.

When her mother dies, she moves to Amsterdam. That is where her daughter marries a Dutch merchant and moves to Surinam – that was a colony at the time, named Dutch Guyana.

In 1699 she is granted the permission to travel to Surinam. She takes her younger daughter with her. They were supposed to spend 5 years there and to finance the mission she sold over 250 of her own paintings.

During her stay in Surinam she criticised the treatment of black slaves and natives and moved around, sketching the local plants and animals. After two years she caught malaria and had to return to Amsterdam in 1701.

For the next few years she took care of publishing her engravings. In 1705 she published another book, focused on insects from Surinam – the first work ever on its local natural history.

In 1715 Merian had a stroke that left her paralysed. She still tried to work, but it was greatly affected. On January 13th 1717 Maria Sibylla Merian dies in Amsterdam. Her last work is published after her death.

Even though she became famous when still alive, she was quickly forgotten afterwards. Only in 20th century her work became popular again and Merian’s face eventually appeared on the German mark banknote before German converted to euro. Year 2017 was the 300th anniversary of her death with many events held in her memory. Google Doodle was made in her memory on the 366th anniversary of her birth in 2013.

Maria Goeppert Mayer was a German-born American theoretical physicist, and Nobel laureate in Physics for proposing the nuclear shell model of the atomic nucleus. She was the second woman to win a Nobel Prize in physics, after Marie Curie.

Long before Goeppert-Mayer stood on that stage in Stockholm, however, she had already made some major contributions to physics. While still a graduate student in Gottingen, she predicted the phenomenon of double photon emission. This occurs when two photons are absorbed by a molecule simultaneously, causing the molecule to move to a higher energy state.

While working in Chicago after World War II, Goeppert-Mayer became interested in understanding why some atomic nuclei were inherently more stable than others. She made a list of the most stable nuclei and found that there were some magic numbers of protons and neutrons that kept turning up in particularly stable nuclei. She wondered why that should be happening, since it didnt fit with the currently accepted model of the structure of atomic nuclei.

In the nuclear shell model, protons and neutrons are located in distinct energy shells, and they are paired with other protons and neutrons. When the highest energy shell present in the nucleus is full, then the nucleus will be very stable, and when it is not full, the nucleus will be less stable.

Katherine Coleman Goble Johnson (born August 26, 1918) is an African- American mathematician who made contributions to the United States' aeronautics and spaceprograms with the early application of digital electronic computers at NASA. Known for accuracy in computerized celestial navigation, she conducted technical work at NASA that spanned decades. During this time, she calculated the trajectories, launch windows, and emergency back-up return paths for many flights from Project Mercury, including the early NASA missions of John Glenn and Alan Shepard, and the 1969 Apollo 11 flight to the Moon, through the Space Shuttle program. Her calculations were critical to the success of these missions. Johnson also performed calculations for the plans for a mission to Mars.

Katherine Johnson after she had got her degree in mathematics, have become a teacher, due to the fact that world of science hasn't been opened for womans yet. After a few years of working, in 1953 she has been offered a job that she accepted and in that way has became a member of the NASA team.
