Today many people say that women have the same chance as men in society. But this was not always so. In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work..
One woman who showed that women should have the same chance was Marie, a scientist. In the 1800s scientists knew that a metal, uranium, gave off radiation. They also knew how much radiation came from his element. But they didn’t know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, But it gave off 4 times as much radiation as usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material.
In 1898 Marie Curie set out to find out this new source of radiation, which she named “radium”. Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, And one morning in 1902 Marie found the source of the radiation.
Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.
