This is a timeline of women in science, spanning from ancient history up to the 21st century. While the timeline primarily focuses on women involved with natural sciences such as astronomy, biology, chemistry and physics, it also includes women from the social sciences (e.g. sociology, psychology) and the formal sciences (e.g. mathematics ...
On February 12, 1961, the Soviet spacecraft Venera 1 was the first flyby probe launched to another planet. However communications with the probe failed before it could complete its mission. [30] Venera 3, which also lost contact, marked the first time a man-made object made contact with another planet after it impacted Venus on March 1, 1966. [31]

Invented in 1952 by Virginia Apgar. Disposable diapers The first disposable diaper was invented in 1946 by Marion Donovan, a professional-turned-housewife who wanted to ensure her children's cloth diapers remained dry while they slept. [12] Donovan patented her design (called 'Boaters') in 1951.
The first woman to go to space was Valentina Tereshkova. She flew in 1963 but it was not until the 1980s that another woman entered space again. All astronauts were required to be military test pilots at the time and women were not able to join this career. This is one reason for the delay in allowing women to join space crews.
Was the first U.S. spacecraft to reach another celestial body. Failure in the onboard computer prevented it from carrying out its scientific objectives. First spacecraft to impact the far side of the Moon. [7] [8] April 26 UK: Ariel 1: Thor-Delta: Earth Success: First British satellite in space (on American rocket) July 10 US: Telstar 1: Thor ...
The idea of using atomic transitions to measure time was first suggested by the British scientist Lord Kelvin in 1879, [204] although it was only in the 1930s with the development of magnetic resonance that there was a practical method for measuring time in this way. [205] A prototype ammonia maser device was built in 1948 at NIST. Although ...
The Association for Women in Computing was one of the first and is dedicated to promoting the advancement of women in computing professions. [228] The CRA-W: Committee on the Status of Women in Computing Research established in 1991 focused on increasing the number of women in Computer Science and Engineering (CSE) research and education at all ...
