Marie Cure Essay

In the early 1900’s, the discovery of a luminescent material, radium, arrived on the scene to the delight of a fascinated and eager public. At first, it seemed to be a miracle remedy, not just harmless but even beneficial. However, when a multitude of watch dial painters were exposed to this substance on an extremely consistent basis, the negative effects began bubbling to the surface. These “Radium Girls” were unknowingly consuming a potentially lethal substance and would be the first victims of radium poisoning and radioactivity. Not many people knew about the dangers of radioactive substances or radium poisoning and many others had made judgements that were clouded by the perfection of the glowing sensation. In spite of this, the horrific afflictions that the Radium Girls endured helped shift the public perspective of radium from “wonder drug” to “pitiless poison” and started the country on a path to regulating the handling of radioactive

Born to Helen and Ivan Daly on April 16th, 1921, Marie was a bright and beautiful child. She grew up in Queens, New York. Her father, an immigrant from the West Indies, was avidly interested in science, and he would’ve continued to study chemistry if a lack of money hadn’t got in the way, forcing him to drop out. Her mother, on the other hand, was from Washington D.C., and she loved to read.

Marie Antoinette is possibly one of the most famous French Monarchs. Born an Austrian princess, she because one of the last monarchs to rule the French, Marie Antoinette has had a major impact on French History but, most importantly, the French Revolution. Unfortunately, she isn’t remembered as a great queen or ruler, but because of the way her and her husband died on the guillotine.

Marie Daly was born April 16, 1921. She grew up in Corona, Queens, New York. Her family believed in the power of education. That's why she spent most of her time in school and studying her books. She enjoyed reading a lot. Marie was educated at Hunter College High School. Hunter College High School

When Henri Becquerel discovered radioactivity in 1896, it inspired Marie and Pierre to investigate it further. They researched a lot of substances for any signs of radioactivity, and discovered something that was more radioactive than uranium. They discovered radium, an element that damaged tissue, so they used that to fight against cancer. “They found that the mineral pitchblende was more radioactive than uranium and concluded that it must contain other radioactive substances. From it they managed to extract two previously unknown elements, polonium and radium, both more radioactive than uranium” (Nobel Media). These discoveries led to radium being used to treat cancer and other diseases, and them getting their first Nobel Prize in Physics in 1903. After Pierre passed away, she continued with her own studies. Marie successfully isolated radium and proved its existence. She also studied the properties and compounds of these radioactive elements. “She also documented the properties of the radioactive elements and their compounds. Radioactive compounds became important as sources of radiation in both scientific experiments and in the field of medicine, where they are used to treat tumors” (Nobel Media). This discovery led to the further development of X-rays and her receiving her second Nobel Prize in Chemistry in 1911. Marie Curie was the first woman ever to win two Nobel Prizes in two fields and in multiple sciences, two incredible

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

In the article “Unteaching the Five Paragraph Essay”, Marie Foley intere that the five paragraph essay format is blameworthy of high school graduate unpreparedness for college coursework and the need of remedial classes. Foley stated that “Many college freshman enter composition course alienated from writing”(P.2) Foley also claim that “teaching the five paragraph formula this harms student in some fundamental ways….i'll-preparing them for academic and real world writing”(P.3) This paper is going to analyse Marie foley article by brake down the reason and problem behind the Five paragraph essay.

My paper is about Irene Joliot – Curie the Nobel – Peace Prize winner that created the first artificial radioactive element. Her life was very successful and fulfilling. Irene’s life was very successful, because she accomplished many things and inspired future scientist. Her and her mom’s work was very useful in World War I. Her work with radiation also became very important to new discoveries of atoms.

She was born on the 17th of February 1821 in County Sligo, Ireland. Her family then moved to India and shortly after her father died of cholera, which is a disease. Her mother then remarried a year later. She was then sent back to the British Isles (a group of islands in Great Britain, Ireland and other smaller isles). Lola was educated in England and Scotland. When Marie was 16 she ran off with Lieutenant Thomas James and then they separated five years later.

The idea that nuclear fission could be a significant producer of electrical power and a powerful military weapon occurred to many physicists, engineers and scientist around the world. Due to the escalating conflict in Europe, many scientist no longer published their discoveries and advancements for fear of it aiding enemy scientist. There was one difficulty encountered early on in the development of Manhattan Project, this problem was the difficulty of mining or creating the proper uranium isotope. Uranium-235 was the only isotope of uranium that underwent fission and only 0.7% of the uranium found in nature was of this isotope. More commonly uranium-238 was found, which actually inhibited the nuclear chain reaction. There were however several techniques which will be mentioned later for enriching the uranium. Do to how rare and expensive uranium-235 was it was first necessary to determine how much would be needed to create fission reactor or bomb.

His discovery to radioactivity helped a lot of other scientists. If Henri hadn't discovered it Ernest Rutherford

Curie thus began studying uranium radiation and made it her doctoral thesis. With the aid of an electrometer built by Pierre, Marie measured the strength of the radiation emitted form uranium compounds and found it proportional to the uranium content, constant over a long period of time and influenced by external conditions. She detected a similar immutable radiation in the compounds of thorium. While checking these results, she made the discovery that uranium pitchblende and the mineral chalcolite emitted four times as much radiation as their uranium content. She realized that unknown elements, even more radioactive then uranium must be present.

     It was not easy for Marie and Pierre to convince the science community of their new findings. Marie succeeded in separating the radium from the barium, but it wasn't easy. She had to treat very large amounts of pitchblende, but she had plenty of pitchblende to use. (The Curie's

I chose to do my project on Marie Curie, the woman who discovered radium and polonium. She was born Mary Sklodowska on November 7, 1867 in Warsaw, Poland and died July 4, 1934 in Passy, France at the age of 67. In 1895, Marie married a professor named Pierre Curie at the age of 26. She was the first woman to complete a doctorate in France in MMMM at the age xxx. And in MMMMM, Curie was also the first female professor at the Sorbonne. She was the first person to use the term “radioactivity”, which is the term still used till this day.

With her experiments, she became the first woman in France to get a doctorate. Curie decided to continue Henri Becquerel’s experiments with X-rays. She came up with the groundbreaking idea that the rays were actually an atomic property. The paper she wrote reporting her discoveries had to be presented through her professor because women weren’t allowed to address the Academy of Sciences. With this, she continued her work to find new elements. First, she found polonium, which is named for her home country, and then she discovered radium. Pierre and Marie’s greatest work was done in a run-down shed. They worked from 1898 to 1902. The Curies could have made a fortune if they patented their process of extracting and refining radium, but they decided share their knowledge with the world.
