The Lady of Luminosity: Henrietta Swan Leavitt

One of the most prominent contributors to the field of astronomy has never actually used a telescope. Unfair discrimination against women forbids one of the most prominent 20th century astronomers actually seeing the stars she is studying. However, this did not matter because Henrietta Swan Leavitt challenged the inferiority and incapacity of these women by entering the dominant male dominant male field. The surprising discovery of the time between Cepheid variable stars by Henrietta Leavitt - the relationship of light will forever change the perception of our universe and known galaxies and lay the foundation for astronomers like Harlow

Henrietta Swan Leavitt (1868-1921) is an American astronomer who has revealed the relationship between light intensity and Cepheid variable stars. It is called "Leavitt's Law" and allows astronomers to measure the distance between the Earth and distant galaxies. Through Leavitt's pioneering work, Edwin Hubble has decided that the universe is expanding. Environmental and industrial chemist Ellen Swallow Richards (1842-1911) changed the face of the modern family through science. Richards created the term "ecology" and used scientific information for nutrition. In the industrial setting, Richards also adopted the water quality standards of the first state of the United States and the first modern city sewage treatment plant. She also created a magazine known as Journal of Family and Consumer Science.

Henrietta Swan Leavitt is an American astronomer who discovered the relationship between lightness and cycle of the Cepheid variable. Rabbit graduated from Radcliffe University and in 1893 he worked as a "computer" at the Harvard University Observatory and began studying the photographic version to measure and catalog the brightness of stars. Although she was not aware of anything in her life, her discovery first enabled astronomers to measure the distance between the Earth and a distant galaxy. "You can easily draw a straight line between each of the two series of points that correspond to the maximum and minimum values, indicating that there is a simple relationship between the brightness of the variable and its period I will.
