In “Intersectionality,” Dr. Vivian May includes leading feminist scholars’ definitions of the term intersectionality, as well as her interpretations of what the word signifies. May refers to intersectionality as a “consideration of marginalization regarding lived experience and social structure” (81). While, in a TED Talk, Dr. Kimberlé Williams Crenshaw describes intersectionality as “oppressive institutions (like sexism and racism) overlapping and creating multiple levels of social injustice”…

logarithmic functions. However logarithmic functions are associated with many other areas of science. We use logarithm in such that the decibel scale for the loudness of sound, the Richter scale of earthquake magnitudes, and the astronomical scale of stellar brightness are all logarithmic scales. When we want to calculate radioactive decay, we use logarithmic functions. We know that radioactive atoms decay randomly.” If we have a sample of atoms, and we specify a time interval short enough…

NGC 584 is an elliptical galaxy in the constellation Cetus. The galaxy was discovered on 10 September 1785 by the German-British astronomer William Herschel. Number 20 in the Herschel 400 list is NGC 584. NGC 584 is a moderately large and bright elliptical galaxy in Cetus. In an 18 inch telescope it appears as an elongated patch of light with a bright center. The two bright galaxies either side of NGC 584 are the 13.2 magnitude NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While…

Describe the development of single dish radio telescopes and advantages of radio interferometers. Discuss major discoveries that were possible after detection of radio waves from space and how they changed our understanding of Universe. Astronomy is all about increasing our understandings about our Universe through observing objects like stars, galaxies and other bodies which exist outside Earth’s atmosphere. Astronomers make observations of these celestial phenomena by collecting…
