Maria Goeppert Mayer was born on June 18, 1906 in Katowice, Poland. Mayer has made numerous contributions to the field of physics. Not only was she the first person to investigate the phenomenon of double quantum emission and double beta decay; She was also the first person to work out the atomic properties of transuranic elements as well. She was a member of the National Academy of Sciences and a corresponding member of the Akademie der Wissenschaften in Heidelberg. Mayer received honorary degrees of Doctor of Science from Russel Sage College, Mount Holyoke College and Smith College. She was a professor of physics and a very accomplished physicist. She was also the first person to investigate the theoretical basis of nuclear pairing …show more content…
Her father was a professor of pediatrics and the seventh generation of university scholars in his family. Because of her family's pedigree in education, it was highly expected that she acquire an education for herself. However, at first, Maria Goeppert Mayer did not intend to become the famed physicist she is today. She originally had the idea of becoming a mathematician in the spring of 1924 when she enrolled at the University at Göttingen. Göttingen was then a world center for physics (and the new study of quantum mechanics). Maria Goeppert had studied mathematics and science, preparing for a university education. She began by studying mathematics, but being exposed to the ideas of such people such as the great Niels Bohrs and Max Born, led Göppert to switch to physics for her choice of study. This switch led her to a great path and successful career in physics. She became a student of Max Born --- a physicist with a strong foundation in mathematics too. Maria was well-trained in the mathematical concepts that would be required to learn quantum mechanics. Even then, once reading her thesis, it was shown that she was highly influenced by James Franck's non-mathematical approach to physics. In 1930, she completely this thesis and received a …show more content…
Goeppert Mayer taught at Sarah Lawrence College between 1941 and 1945, but she worked mainly at the S. A. M. Laboratory, on the separation of isotopes of uranium, with Harold Urey as director. She was also employed by the Argonne National Laboratory. In 1948 she started to work on the magic numbers, but it took her another year to find their explanation, and several years to work out most of the consequences. The fact that Haxel, Jensen and Suess, whom she had never met, gave the same explanation at the same time helped to convince her that it was right.. During her time at Chicago and Argonne, Maria developed a mathematical model for the structure of nuclear shells. She conducted inquiries about the elements sources and noticed the repetition of seven “magic numbers", with the help of Edward Teller. The numbers were 2, 8, 20, 28, 50, 82, and 126. It was shown that elements with a “magic number” of protons or neutrons were consistently more stable than elements with other numbers of protons or neutrons. She proposed that in the inside the nucleus, protons and neutrons are arranged in a series of nucleon layers, like the layers of an onion, with neutrons and protons rotating around each other at each level. During the same time but working independently, German physicist J. Hans D. Jensen reached the same
After Anna graduated from the University of South Dakota she began graduate work at the University of Iowa. She then made a thesis The extension of Galois theory to linear differential equations, which earned her a masters degree in 1904. One year later she earned a second graduate degree from Radcliffe College. At Radcliffe College she took courses from Maxime Bocher and William Fogg Osgood.
Rosalyn Sussman Yalow graduated Hunter College as the first women to graduate in physics (Bauman et. al. 2011). She also led a way for acceptance and understanding of women’s role in science in America (Bauman et. al. 2011). She even inspired Mildred Dresselhous, who was a professor at Massachusetts Institute of Technology (MIT) and president and officer of many Associations including American Association for the Advancement of Science, to pursue the career she wanted (Bauman et. al. 2011). Rosalyn born to Clara and Simon Sussman in New York City, on July 19, 1921 (Brody 1996). She married Aaron Yalow on June 6, 1943 and had two children named Elanna and Benjamin (Brody 1996). In 1977, Dr. Yalow won the Nobel Prize in medicine and was the second women to ever accept such an award (Brody 1996). She also taught physics in New York until 1950 when the Veterans Administration (during World War II) was interested in exploring and researching radioactivity (Brody 1996). As her life progressed, Dr. Rosalyn Sussman Yalow became an inspiration for young women who want to be recognized and achieve something in their life (Brody 1996). From when she was a child she was fascinated with science and decided to achieve something no women really does. Rosalyn Yalow went to school and started working in the science field, she managed to help the world of radioactivity and radioimmunoassay, how Mrs. Rosalyn impacted the world of science, how Dr. Yalow impacted the lives of other women, and how she never lost her passion for science even in her last years.
...acknowledged as the greatest women mathematician of the 1900’s, even though she had to go through many obstacles and chauvinism. She was the first women to be accepted into a major college. She proved many of the stereotypes that women were considered to be erroneous, which in the long run also made her a famous person. She was the one who discovered the associative law, commutative law, and the distributive law. These are the Laws that make the basics for Algebra, Geometry, and Basic math. All together she has unquestionably earned the title as the most famous woman mathematician of the 1900’s.

Marie Curie (1898-1934): Marie Curie was a Polish physicist and chemist who conducted pioneering research on radioactivity. In 1903, she shared the Nobel Prize in Physics with her husband, and in 1911 won the Nobel Prize in Chemistry. She was the first woman to win a Nobel Prize, the first person and only woman to win the Nobel Prize twice, and the only person to win a Nobel Prize in two different sciences. Through her experiments she developed the theory of radioactivity and techniques for isolating radioactive isotopes, as well as discovering two new elements: radium and polonium.
Marie Curie opened the world up to the science of radioactivity. She discovered polonium and radium, two radioactive elements, and was the first person to ever win two Nobel prizes and in two different subject areas. To the modern world, her discovery of radium was significantly and forever changed our understanding of how matter (atoms) and energy (radiation) are related. Her efforts influenced and expanded theories dealing with fundamental science and brought in a new era of medical research and treatment.
It was Italian-born physicist and Nobel winner Enrico Fermi, and his colleagues at the University of Chicago who were responsible for this success (“Nuclear”).
Michael Guillen, the author of Five Equations that Changed the World, choose five famous mathematician to describe. Each of these mathematicians came up with a significant formula that deals with Physics. One could argue that others could be added to the list but there is no question that these are certainly all contenders for the top five. The book is divided into five sections, one for each of the mathematicians. Each section then has five parts, the prologue, the Veni, the Vidi, the Vici, and the epilogue. The Veni talks about the scientists as a person and their personal life. The Vidi talks about the history of the subject that the scientist talks about. The Vici talks about how the mathematician came up with their most famous formula.

MARIE CURIE AND THE STUDY OF RADIOACTIVITY Marie Curie was born, Maria Sklodowska, on November 7, 1867. She grew up in Warsaw, Poland. She would become famous for her research on radioactivity. Marie Curie was the first woman to ever win a Nobel prize, and the first ever to win two Nobel prizes. She is most famous for the discovery of Radium and Polonium.
She made an equation that describe the drop-offs in women in science and shared it in one of her lectures. “In the few years before that, I had started thinking about why there are so few women in science overall and I had started collecting data. I started out this lecture with an equation- a birth and death equation- and I showed the statistics I had gathered about how the percentage of women drops off dramatically throughout the academic ladder and I asked, what is killing them off?”
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
During the seventeenth century, the modern science of physics started to emerge and become a widespread tool used around the world. Many prominent people contributed to the build up of this fascinating field and managed to generally define it as the science of matter and energy and their interactions. However, as we know, physics is much more than that. It explains the world around us in every form imaginable. The study of physics is a fundamental science that helps the advancing knowledge of the natural world, technology and aids in the other sciences and in our economy. Without the field of physics, the world today would be a complete mystery, everything would be different because of the significance physics has on our life as individuals and as a society.
