the following presentation is brought to you by Discovery Education in the world of digital and video learning Discovery Education to a world of learning Maria Marie sklodowska Curie was born on November 7th 1867 in Warsaw Poland and died on July 4th 1834 in Geneva Switzerland Mary Curie was an Innovative scientist who with her husband Pierre performed pioneering research but vastly expanded the world's knowledge of radioactivity she discovered the elements radium and polonium won Nobel prizes in physics and chemistry and greatly Advanced scientific and medical terminology through her work what in Warsaw Poland in 1867 Marie Curie spent most of her life in France where she discovered radium and put the word radioactivity in two common uses the winner of two Nobel prizes Cherry helps create an Uber physic and trained x-ray technicians to serve on the front lines of World War 1 during her 1921 trip to the US carry was getting a precious gift by President Harding a single gram of radium a valuable resource for her research at the radium Institute the object of Marie Curie studies can be found here deep underground contained in the shiny black mineral called pitchblende friends with already known as a source of radioactive uranium but Marie Curie and her husband Pierre were the first to determine that after the uranium was removed the remaining or with more radioactive than the uranium itself. using supplies of pitchblende or obtain chiefly from mines in the Western United States victories work to identify the radioactive substances breaking the door down through many chemical processes they finally isolated two new radioactive element which they name radium and polonium radium is present in Pitch Blend or in such low concentrations that it takes a ton of ore to produce a quarter gram of the precious element radium Discovery had far-reaching consequences do her research with radium Curie open new avenues of medical technology and brought hope to victim cancer and other related diseases President Hoover on behalf of the American friends of science presented Kure with $50,000 to purchase radioactive materials for her radium Institute Marie Curie and her husband Pierre along with another French scientist Antoine on Rebecca Rowe were awarded the Nobel Prize in physics in 1903 three years later tragedy struck when her husband Pierre was killed by a horse-drawn carriage in the streets of Paris taking over his physics professorship at the University of Paris Siri continued her research while raising two young daughters he went on to win the Nobel Prize again in 1911 this time for chemistry who is the scientist to research tirelessly challenge once insurable illnesses and open the secrets of radioactivity scientific study this was Marie Curie Marie Curie a lifetime of achievements Marie Curie received master's degrees in physics and math she was the first woman to receive a doctorate in France for the thesis on radioactivity are discovered to radioactive elements radium and polonium Marines revolutionary hypothesis that the initiative raised by uranium compounds could be Atomic property rhenium ushered in a new era of fundamentals medical research and treatment she coined the word radioactivity to describe the behavior of 1803 Curie won the Nobel Prize for physics with her husband Pierre for discovering the Radioactive elements of radium and polonium and with French physicist Antoine becquerel discovered natural radioactivity she was the first woman to win the Nobel Prize in 1911 Marie Curie won the Nobel Prize chemistry for isolating radium and studying chemical properties she helped found the radium Institute in Paris after her death and was the first director it became a world center for the study of radioactivity during World War 3 recognized the need for surgeons on the front lines to have accessed portable x-ray equipment she invented Radiology transport x-ray apparatus into the battlefield he served error cell Alex created the Curie Foundation which became a major International for treatment of cancer radioactivity was published posthumously Jimmy participated in the condition of the French Academy of Medicine that recommended the use of lead screen in blood tests for radiology workers cooperation for the League of Nations established an bibliography of scientific papers develop standards for international scientific scholarship and protected researchers ownership of intellectual rights for their discoveries Albert Einstein was born on March 14th eighteen 9th and Burton Berg Germany and died on April 18th 1955 in Princeton New Jersey Einstein's concept of time space Mass motion and gravitation revolutionized scientific his theories of Relativity the atomic theory of matter the unified field Theory and his interpretation of the photoelectric effect created a new branches of physics you received a Nobel Prize in physics for his discovery of the law of the phone electric fat Einstein's Formula E equals MC square forms the basis for the development of nuclear energy and the atomic bomb the 19th America received the Renown visitor from Germany Albert Einstein recipient of the Nobel Prize in physics Einstein was internationally recognized as the genius who is revolutionary mathematical theories that a rock foundations of science what are the most influential figures of the 20th century Einstein was Jewish and a scientist in an anti-semitic anti-intellectual Nazi Germany in 1933 the Nazi government seized just property removed him from his university positions and took away his citizenship Einstein immigrated to the United States that same year America welcome Tim is future work would lay the foundation for the development of nuclear energy and would have far-reaching effects on nearly every branch of science given X Moana Mystic River Mystic Einstein quest for scientific truth combined philosophical thought with complex mathematical reasoning his tools for pencil paper and an enormous intellect born in 1870 this gifted scientist who published his first theory of relativity by the age of 26 it was a decade before other scientists develop the technology for experiments to prove his theory universities all over the country offered him positions on their faculties but he headed for New Jersey and a quiet Princeton campus that was to be his laboratory and home until his death in 1955 in 1935 Einstein received the Franklin medal for his work in theoretical physics because of his loyalty and concern for the United States Hitler did President Roosevelt the Germany was nearing the nuclear age and that America must get there first this marks the beginning of the Manhattan Project and the development of the atomic bomb in 1947 instance Bicentennial celebration leaders such as general Eisenhower and President Hoover and Truman helped the university honor its recently retired Professor Albert Einstein statesmanlike Israel's Ben-Gurion were United in their upper Nation for Einstein a brilliant Visionary who changed the world Albert Einstein a lifetime of achievements Einstein's document the 19 5 papers resulted in three new branches of physics Quantum Theory special theory of relativity and the atomic theory of matter in 1915 Einstein announced his general theory of relativity why did the study of the unified field Theory he received the Nobel Prize in physics in 1921 first quantum theory which established a theoretical basis for the photoelectric cell and made sound Motion Pictures tell a and other inventions possible Einstein's Formula E equals MC squared became the foundation for the development of nuclear energy he is considered one of the fathers of the nuclear age in 1935 he received Franklin award for outstanding achievement in science and technology in 1939 Einstein wrote the now-famous letter to President Franklin Roosevelt urging him to build the atomic bomb before Nazi Germany did this launch the Manhattan Project and the US produce the atomic bomb in 1945 Einstein was offered the presidency of Israel in 1952 but declined the offer just before his death 1855 Einstein cosign the Russell Einstein Manifesto warning of the nuclear threat this publication lay the foundation for the modern peace event Jonas Salk was born October 28th 1914 in East Harlem New York and died on June 23rd 1995 in La Jolla California Salk an American Research scientist is best known for developing the first effective vaccine for infantile paralysis or polio his achievement end of the great polio demyx of the 1940s and 50s he also established the Salk Institute for biological studies as research on the causes and treatments for a range of diseases such as cancer AIDS Alzheimer's and by the 1950s polio outbreak in America had reached epidemic levels in 1954 Dr Jonas began testing a new polio vaccine almost half a million children were inoculated with his vaccine children in the control group received injections without the vaccine in them this was the largest medical test of its kind ever done in all more than a million and a half children were involved in this huge scientific test children and young people were the most frequent victims of polio this crippling disease struck without warning in the two years before a vaccine was widely available the average number of polio cases in the US was more than 45,000 per year this is the enemy the poliovirus it can affect the central nervous system infecting cells that control muscle function the result pain paralysis and even death dr. Salk vaccine was composed of polio virus that have been killed with formaldehyde a person inoculated with the vaccine would produce antibodies that would attack a live virus that entered their body in 1955 after a year of testing the results were presented at the University of Michigan doctor stock was as concerned as other parents since he also had a growing family Kali dr. Thomas announce the results of the study the vaccine had proven safe and effective not one child who had the vaccinations died of paralytic polio stop tears of Labor had paid off he became an international hero Dr sachdev his hat in the back seen nor did he earn any money from his Discovery he preferred to see it distributed as widely as possible 1862 the number of polio cases in the US have dropped from 45000 to only 910 today the Western hemisphere is in effect polio-free thanks to stop start Discovery there are hopes to someday eliminate polio worldwide doctor stop disease research continues at the Salk Institute continuing to represent the humanistic interests of its Visionary namesake Jonas Salk a lifetime of achievements during World War II Jonas Salk helped develop a flu that seen used by the Army in 1947 salt was appointed director of the virus research laboratory at the University of Pittsburgh School of Medicine by 1949 Celica becomes polio research with funding from the national Foundation infantile paralysis now the March of Dimes in 1953 silk announced the development of a trial vaccine testing followed in 1954 involving 1830000 children successive polio vaccine was announced in 1955 and mass immunization begin with school children with mental for great achievement in the field of Medicine in 1963 the Salk Institute for biological studies in La Jolla California was founded Salt continued his research into the cause and treatment of infectious disease until his death on June 23rd 1995 Guglielmo Marconi was born on April 25th 1874 and died July 20th 1937 in Rome Italy Marconi was a remarkable Italian inventor and go engineer who is determined to give the world a system of communication based on electromagnetic waves he gained International Fame for his revolutionary advances in Wireless telegraphy or radio is in Mainstays broadcast radio possible and lay the foundation for development of the first air defense radar Network Galliano Marconi was born Bologna Italy on April 25th 1874 the son of a wealthy Italian landowner he became famous for his invention of a practical system of long distance Wireless communication amongst 17 The Faculty of Columbia University awarded Marconi an honorary doctor of Science degree for his achievements he registered his first patent in 1897 for assist Wireless telegraphy 2 years the life-saving possibilities of Wireless transmission we recognize when a ship in distress signal for help he established his place in history in 1901 when he received the first transatlantic Wireless communication that when what's the Atlantic Ocean from Cornwall England to Newfoundland in 1933 Marconi and his wife went to Hawaii by then a network of radio communication broadcasting and navigational AIDS have been established WYD that same here David Sarnoff the president of the radio Corporation of America welcome to Marconi's do New York he too had come a long way since his first job in 1906 when he had been an office boy for them Tony Wireless telegraphic Company of America start-off took his old friend to Rocky Point Long Island to visit the first commercial Wireless station ever built in the United States both these men would continue to significantly influence the communication industry in the future Marconi inspected the RCA headquarters with sonoff who personally had done much to bring attention to Marconi's inventions on April 14th 1912 as a wireless operator at the Marconi Station in New York sun off received first distress signals from the Titanic and told the world that great tragedy turn off stayed on duty for 72 hours releasing names of survivors and getting details of the disaster none of this would have been possible without inventive Genius of go yellow Marconi Marconi John in Rome on July 20th 1937 back in 1895 when he first offered his Wireless transmission system to the Italian government it would turn down but the British saw the possibilities of wireless and encourage Marconi's Enterprise with the formation of the Marconi Wireless Telegraph Company Limited Global Communication without wires with made possible Tony's vision and invention open the doors to the wireless communication advances we enjoy and depend on today Coney a lifetime of achievement in 1894 at the age of 20 distance without wires after filing the world's first patent for some of the wireless telegraphy 1896 successfully demonstrated Telegraph and Signal Company in 1897 1899 wireless communication was established between France and England across the English Channel the East Goodwin Lightship was first to use Marconi's device to signal for assistance at sea in 1901 transmitted the first transatlantic communication patterns years he shared the 1909 Nobel Prize physics, Germany between 1920 and 1922 numerous advances were made in public broadcasting using Marconi technology including the first regular public entertainment program in 1924 did shortwave directional transmission called The Beam system making shortwave radio and effective and reliable method of communication continuing his research play the Practical demonstration of the principles of radar in 1935 two years before his death at the age of 63 Society of the John Fritz metal the Calvin end the Grand Cross of the order of the crown of Italy Thomas Edison was born on February 11th 1847 in the land Ohio and died October 18th 1931 in Llewellyn Park New Jersey Thomas Alva Edison is considered one of the most influential figures of the 20th century he is more responsible than anyone else for creating the modern world we know today is contributions include the invention of the incandescent light bulb practical lighting the phonograph and improvements to the Telegraph telephone and motion pictures Edison established one of the first Research Laboratories and have patents on 1093 inventions in 1876 Thomas Alva Edison a young man born in Ohio moved to Menlo Park New Jersey he did not have a formal education and was parked but he became the inventor genius who brought her Oculus changes to the world where does genius begin Edison once said genius is 1% inspiration and 99% hard work the youngest of seven children from an early age he showed signs of the intelligence and drive that would result in hundreds of revolutionary inventions Edison created one of the first modern research Laboratories in which to conduct his experiments many people think this Innovation his greatest achievement he worked side-by-side with his assistants some of them stayed with him throughout their working lives others went on to have brilliant years of their own because of their experience with him known as The Wizard of Menlo Park Edison was also a good businessman he designed new devices based on what people needed and would use he built his business around the in canndescent light bulb here is an actual recording made on his first phonograph with the invention of the kinetoscope in 1891 Edison pave the way for modern Motion Pictures after further refinements including a projector be produced America's first film classic The Great Train Robbery here he is seen using another of his Vengeance the time clock Edison was famous for putting in long hours at his laboratory for the rare hours when he was not working you would relax it is home in nearby Glenmont New Jersey married twice and was a father of three children however his work often overshadowed his family life Thomas Alva Edison was driven by his vision of the future he successfully Blended the imagination of the dreamer with the practical Outlook of a businessman to bring his ideas to the world Thomas Edison in 1862 at the age of 15 Addison printed and published the weekly Herald the first newspaper to be printed and published a board a moving train at age 16 came up these first authentic invention the automatic repeater which allowed virtually anyone to translate Minecraft code at their own speed in 1868 Edison applied for and received his first patent an electric volt recording machine politicians refuse to use it Italian votes to quickly shortly after moving his labs in Menlo Park New Jersey Edison invented the phonograph in 1877 in 1879 Edison patent to the first commercially practical incandescent electric light bulb free 1883 and 1884 he introduced the world's first practical system for centrally generating and distributing power light and heat Edison Salvage the world's first research and development center in West Orange New Jersey 1987 it became the model for such labs in the future in 1891 working with fellow inventor William Dixon Edison invented the kinetoscope the Forerunner of the Motion Picture film projector around the turn of the century Edison invented the first practical dictaphone mimeograph and storage battery following the invention of the kinetoscope and first silent films Essence attempt to blend picture and sound resulted in the 10-minute film classic Great Train Robbery 1903 during World War 1 the adventure Focus his creativity upon developing defensive devices for submarines and ships on May 29th 1928 Edison received the show Medal of Honor and appreciation for distinguished achievements and contributions to the nation in 1931 Thomas Edison died at his home in New Jersey by the time of his death at age 84 he had obtained one 2093 patents
