Michael Faraday was an English scientist who lived in the 1800's. Faraday always had a interest in being a scientist but because of his low class in society it was almost impossible. His big discovery was that, electricity traveling through a wire gives off an electrical force. He came up with the idea of this when the scientist he worked with was putting a compass on eieither side of a electricfied wire. The needle of the compass the deflected at right angles. Late on he preformed is own experiment
Radiation and its Effects on the World The biological effects of radiation play a key role in today’s society and it is something that all species have to deal with on a day-to-day basis. Throughout time, this field of study has grown and has become one of the most prominent fields of science. Radiation is something that we as a human race will never be able to escape. It is naturally present and has been since planet Earth was formed. In the mid 19th Century, there were two famous scientists that
Over the course of history, there have been many great scientists. Ranging from Enrico Fermi to Albert Einstein, the contributions made by these men and women have dramatically changed society then, now, and forever in the future There are three characteristics which all the great scientists possess, they are all: intelligent, curious, and persistent. These scientists will all be remembered as pioneers in their respective fields because what they did has changed the world forever. The word “smart”
Otto Hahn was awarded the Nobel Prize in chemistry in 1944 for his discovery of nuclear fission. Although his coworkers Fritz Strassmann and Lise Meitner are also credited for the discovery, Hahn took most of the credit. Hahn took much interest in science and worked non stop day and night trying to figure things out. On top of discovering nuclear fission, he is also credited with discovering certain radioactive isotopes and elements. The main reason for Hahn’s success was not his actual academic
1930 Schrödinger views electrons as continuous clouds and introduces "wave mechanics" as a mathematical model of the atom. -------------------------------------------------------------------------------- 1931 Albert Einstein urges all scientists to refuse military work. Harold C. Urey of the United States and associates discover deuterium (heavy hydrogen) which is present (0.014%) in all natural hydrogen compounds including water. John D. Crockcroft of Great Britain develops high-voltage apparatus
the year 1910, this lead him to becoming the head of the chemistry department. Hahn worked with the German army during the first world war, where he created poison for both the west and east front. Hahn after the war concentrated on chemistry, with Lise discovered Uranium Z. In the year 1936, he wrote a book named “Applied Radiochemistry” which was very helpful to many scientist. Later 1930s Hahn and his group were the first to figure out half the life of Uranium. In 1936 Hahn continued discovering
Alchemy was an early form of pseudoscience focused on a mythical substance, the philosopher’s stone. Alchemists had many conflicting views on what the stone was and what its powers were, but it was believed to be very powerful. Uses of the stone included producing the elixir of life, which could cure any illness and prolong life indefinitely, and turning ordinary rocks into precious gems. The main goal of alchemy, “transmuting base metals into gold,” was believed to be possible only when using the
Have you ever wondered why women make up only “10-20 percent” of careers in science and technology? (Countries Must Address). The cause of this is from the media that injects gender stereotypes into our lives. The adroitness used to execute these stereotypes can push women away from STEM careers. Women today are pushed away from STEM careers due to discriminating gender stereotypes, an impact which can be seen through the imbalance in the nation's sex ratio in STEM careers. America’s history addresses
The definition of radiation is the emission of energy electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. One of the scientist who discovered radiation was Henri Becquerel, the way the French scientist discovered radioactivity was when we was conducting an experiment with uranium-bearing crystals to sun light, then put it on a photographic plate, he then had set off his experiment for a few days because it was very cloudy and the sun wasn’t
Nuclear Fission/Fusion There is a lot of information to gather and learn while talking about/discussing nuclear fusion and nuclear fission. Nuclear fission can be defined as a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy. Nuclear fusion can be defined as a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy. Nuclear fission takes place when a large
Why is the Atomic Bomb one of the most important inventions created in the United States? According to research, the atomic bomb is considered an essential invention to have in a country due to its destructive power created by the fission of either plutonium or uranium. Countries across the world would use the atomic device against other countries in order to make advancements. The first atomic weapons that were built for warfare was known as the Little Boy and Fat Man. United States is the first
like radioactive decay, but a much more dramatic reaction. In 1938, Otto Hahn and Fritz Strassmann, working with Lise Meitner, bombarded uranium with neutrons, releasing energy and causing the uranium atoms to split into multiple parts, the nuclei themselves breaking down to create new nuclei with fewer protons, which were the nuclei of smaller atoms. Hahn, Strassmann, and Meitner had produced nuclear fission, the reaction soon to be used in powerful nuclear weapons and power plants. Hahn and
women in this book have won Nobel Prizes, the next page goes into depth of what the Nobel Prize is and how Alfred Nobel started this honorable award. Flipping forward, women such as Gertrude B. Elion, Grace Hopper, Henrietta Leavitt, Sallly Ride, Lise Meitner, Marie Curie, Jane Goodall, and Maria Tharp are introduced. Each women has a page summary of what her achievements were and how she affected the world, accompanied by an activity related to their work. Through these pages, students can learn about
Atomic Theory Historical SHE Task 1. Construct a timeline which shows the development of the modern atomic theory. Include a minimum of 5 and a maximum of 15 significant events in your timeline. 442 BC thinking about matter Democritus, a Greek philosopher, co-originated the thought (with his teacher, Leucippus) that all matter is composed of indivisible elements. 1803 John Dalton and atoms John Dalton, a British chemist and physicist, developed a theory that matter is simply composed of atoms
The Nuclear Era Begins: A Brief Background on the Trinity Project Introduction The 20th Century unleashed a fury of new technologies and discoveries that changed the course of the world. Developments in physics led the charge with the likes of Lise Meitner and Otto Frisch who, in 1939, demonstrated and coined the process of fission. Potentially, no individual discovery influenced the course of history like the development of nuclear fission. With the world at war, and the Axis forces winning on
Human Gender and Mathematics Is there a difference in the mathematical ability between men and women? Historians have no precise method of quantifying or comparing their individual accomplishments (Olsen). Not only in mathematics, but also in many other career areas in the past, women were looked upon as inferior to their male counterparts. Women were not encouraged to pursue a career in mathematics. Historically, women were seen working around the home, cleaning the house, taking care of the
The Atomic Theory is a theory that explains what matter is made of. The Atomic theory states that matter can’t be divided as it is made up of minute particles called atoms that cannot be separated. The very word atom is derived from the Greek word Atmos which means indivisible. Atomic theory timeline- Year Person/People Event 442 BCE Democritrus and Leucippus These Greek philosophers came up with the idea that all matter is composed of indivisible elements. 1803 John Dalton British chemist and
Outline In 1944 the German chemist Otto Hahn was awarded a Noble Prize for his work on nuclear fission - the process that lies at the heart of nuclear bombs and power stations. The Austrian physicist Lise Meitner, who was the official leader of Hahn's team, and who also worked out the theoretical explanation of their experimental discoveries, was not even mentioned in the Noble committee's announcement. (Wertheim) Thirteen years later the Chinese-American particle physicist Chien-Shiung Wu
