Marie Curie once said “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less” (“Marie Curie Quotes”). Many people are fearful of radioactivity and its effects on a person’s health, but Marie Curie dedicated her life to researching radioactivity so more could be understood about radioactivity. Marie Curie was a pioneer in physics and an inspiration for women in scientific fields. Thanks to Marie Curie’s curiosity, radioactivity is something that is understood today, so people can be less fearful. Through the examination of the life and accomplishments of Marie Curie, her influence on the world, especially for her work in physics and chemistry, it becomes abundantly clear that …show more content…
This is an example of one of the many times Marie Curie faced discrimination throughout her career. Then, in 1894, Marie Curie met a French physicist, Pierre Curie, who was studying magnetism and crystals; they were married in 1895 (Des Jardins). Pierre and Marie were both conducting similar research which likely contributed to their relationship. In 1903, Marie Curie was the first woman in France to receive a PhD in physics. “Professors who reviewed her doctoral thesis , which was about radiation, declared that it was the greatest single contribution to science ever written” (Des Jardins). This shows that Marie Curie had excelled in her career despite growing up in poverty. After her husband died in a carriage accident in 1906, Marie was asked to fill her husband’s position at the University of Paris (“Marie Curie Biography”). At Marie Curie’s first lecture, “Hundreds of people - students, artists, photographers, celebrities - lined up outside the university on November 5, 1906, hoping to attend her first lecture” (Des Jardins). This is an
(Brown 166). This radioactive element that workers produce is not just affecting the environment, but is also affecting the workers and their families. Brown has given an immense amount of evidence to explain to the readers how it affected so many of the workers’ health; she gives a vivid picture of how the radioactivity and particles of plutonium linger in the air. The effects to the workers and their family range from cancerous cells to organ deterioration, when a pregnant woman is exposed to it, the health of her baby is also at risk. The fourth and last part of the book is “Dismantling the Plutonium Curtain,” this curtain is the curtain of secrecy.
An influential American printmaker and painter as she was known for impressionist style in the 1880s, which reflected her ideas of the modern women and created artwork that displayed the maternal embrace between women and children; Mary Cassatt was truly the renowned artist in the 19th century. Cassatt exhibited her work regularly in Pennsylvania where she was born and raised in 1844. However, she spent most of her life in France where she was discovered by her mentor Edgar Degas who was the very person that gave her the opportunity that soon made one of the only American female Impressionist in Paris. An exhibition of Japanese woodblock Cassatt attends in Paris inspired her as she took upon creating a piece called, “Maternal Caress” (1890-91), a print of mother captured in a tender moment where she caress her child in an experimental dry-point etching by the same artist who never bared a child her entire life. Cassatt began to specialize in the portrayal of children with mother and was considered to be one of the greatest interpreters in the late 1800s.
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.
Florence Joyner was the American woman, who most female track runners wanted to be like. Many may know Joyner as “Flo Jo”. She was given that name because of her great speed. Joyner is considered to be the fastest woman of all time, based on the fact that she set the world record in 1988 in the 100m dash and 200m dash. Since her death, her records still stands in the 100m dash and 200m dash, running a 10.49 and 21.34. There are very fascinating and inspiring things about Joyner that some people may not know about her.
Marie Curie, originally Maria Sklodowska, was born in Warsaw on November 7, 1867. She was the fifth-born and the youngest child and both her parents were schoolteachers. Marie lived in Warsaw her whole life until her mid-twenties, where she went to school and was also taught math and physics by her father. Her oldest sister and mother passed away during her childhood—her sister dying from typhus and her mother dying from tuberculosis. The deaths in her family caused Marie to become agnostic at the age of fifteen. Due to the fact that she was a woman, Marie was not able to receive a better education at normal institutions so she and her sister involved themselves with Flying University—a university that accepted females as students.
She had many struggles trying to receive higher education because of the restrictions women had when it came to furthering ones education. But after many attempts, she was able to study with the great German mathematician Karl Weierstrass. She worked with him for the next four years and then in 1874, received her doctorate. By this time, she had published numerous original papers in the field of higher mathematical analysis and applications to astronomy and physics. But despite all her attempts, and brilliance, she was still a woman in her time period, and therefore unable to find a job in academia. Weierstrass had tried helping her find a job because he was astonished with her abilities and intellectual capacity, but had no luck because after all, she was still a woman.
Marie Curie and Dorothy Crowfoot Hodgkin both achieved great discoveries for the human society. They saw the invisible of nature as visible in their own perspective. Therefore, their purpose gave them an insight of what seems to invisible to visible. Marie Curie studied the radiation of all attributes of radioactive elements. She then realized that these elements can be measured by their strength. Marie Curie was able to make something that doesn’t seem to exist and make it into existence. Therefore, she proved her hypothesis that there is another element that has a stronger radiation than uranium and thorium. And therefore that was how Marie Curie saw the invisible to visible.
Marie Curie’s impact is felt far beyond the improved understanding of radioactivity and the advancement of the research area of chemistry. Her work and efforts also have made a difference to society in general. She is widely regarded as a role model for female scientists, having been the first women to ever win a Nobel Prize and the only person to ever receive Nobel Prizes in two sciences, which was not easy considering the favoritism towards men in the field during her lifetime. She was also known to be an outstanding person in general, have such high standards and very honest and
The famous marine biologist, Rachel Carson, lived a beautiful, happy childhood. She always wanted to see the sparkling, blue ocean. She grew up just outside Pittsburgh with her mother, father and older sister and brother, Marian and Robert. Rachel loved nature and her mother told her about all the birds and animals. Rachel enjoyed exploring green fields and woods. At school, Rachel was an A student, though was usually absent because she stayed home to study plants and animals. When Rachel was young, she wrote books and at age ten her books were published. Rachel spent her first two years of high school at her elementary and middle school. The other two years were spent at Parnassus High School. Rachel went to college at Pennsylvania College
Rachel Carson had a very exciting life, she never was in the same job for more than five years, always was doing something never sits around. She made many books about wildlife.
“Radioactivity is used in electricity plants, navy submarines and ships, spacecraft in deep space, and pacemakers. Radioactive elements are used in the health field to treat cancer, to conduct various laboratory tests, to sterilize medical supplies, and to diagnose diseases using nuclear medicine images. In other industries, radioactive materi...
Human's understanding of science has evolved because of the contributions made by scientists. Current knowledge of radium is based on the research done by Marie Curie and her husband Pierre. Marie Curie was a famous Polish physicist and chemist. Marie Curie had a science influence during her initial years, worked with her husband in radiation, impacted science and medicine and earned achievements for her studies.
...longed exposure to radiation. Based on all her work, Marie Curie made many ground breaking discoveries in her lifetime. She is the most famous female scientist to have ever lived and received many posthumous honors. In 1995 her and her husband’s were interred into the Pantheon in Paris which is the final resting place of Frances’ great minds. She was the first and only woman to be laid to rest in the Pantheon. Curie passed down the love of science to the next generation. Her daughter Irene followed in her mother’s footsteps by winning the Nobel Prize in 1935. She shared her Nobel Prize with her husband on their work on their synthesis of new radioactive elements.
Rachel Carson was born in May 27, 1907 in Springdale, Pennsylvania. She’s known for her best selling book Silent Spring which talks about the dangers of pollution and how it affects the environment. Growing up she lived in a farm which her mother, taught her to know more about nature and wildlife while her father wasn’t home as much. Her mother had inspired Rachel to be interested in literature which eventually she knew that she wanted to be a writer. However, when she reached to college, she changed her major from English to Biology after she had realized her actual love for Science.
The impact of nuclear power on the modern world has improved Various sectors of the economy and society .i.e. Food and Agriculture, Insect control, Food Preservation, Water Resources, Military, Medicine, Research and Industry. “In 1911 George de Hevesy conducted the first application of a radioisotope. At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials. Not having much money he lived in modest accommodation and took his meals with his landlady. He began to suspect that some of the meals that appeared regularly might be made from leftovers from the preceding days or even weeks, but he could never be sure. To try and confirm his suspicions de Hevesy put a small amount of radioactive material into the remains of a meal. Several days later when the same dish was served again he used a simple radiation detection instrument - a gold leaf electroscope - to check if the food was radioactive. It was, and de Hevesy's suspicions were confirmed.
