Marie Curie decided to study uranium to known more about the rays emitted by it. Her husband had previously invented a device known as the Curie Electrometer which was used to measure electric currents which were extremely low. Marie Curie used this device to study the nature of the rays emitted by uranium and found that uranium in any form; be it wet or dry, solid or pulverized or even pure or in a compounded form; emitted rays which were consistent.

She then validated the theory provided by Becquerel that a mineral with a low amount of u ranium emitted fewer rays than a mineral with a higher concentration. Further, she discovered that the rays coming from uranium depended on the amount of uranium and not on its chemical form. Thus she theorized correctly that the rays were coming from within uranium atoms and not from a chemical reaction.

In , German Scientist Gerhard Carl Schmidt first observed that t horium was also radioactive like uranium. A few weeks later, Marie Curie independently reached the same conclusion but missed the credit for the discovery. While studying the nature of rays emitted by uranium, Marie Curie found that the uranium minerals, pitchblende and torbernite affect the conductivity of air more than pure uranium. Due to this, she correctly theorized that these minerals must be containing other elements which are more radioactive than uranium. Marie Curie, joined by her husband Pierre, decided to find these new radioactive elements which they suspected might be present in pitchblende.

Polonium was the first radioactive element which was discovered by t hem. In July , they published a joint paper announcing its existence. Further, it was was found that polonium was times more radioactive than uranium. While her husband worked on identifying the different physical properties of the new elements they discovered, Marie Curie was more interested in isolating the elements from their mineral form. Pitchblende is a complex mineral and thus this proved to be a very difficult task. In , along with her assistant, Marie Curie was able to successfully isolate a tenth of a gram of pure Radium Chloride from tons of pitchblende mineral. She never succeeded in isolating polonium , which has a half-life of only days. The Curies also found that radium was almost a million times more radioactive than uranium.

Through further studies, it came to be known that radium is a source of heat and has temperature higher than its surroundings. During the course of her research on radioactivity, Marie Curie found that the number of rays emitted by uranium were directly proportionate to the amount of uranium , i. Through further research, she formulated a hypothesis which explained that the emission of rays from uranium was an atomic property of uranium and a result of the structure of the atom. This discovery was significant as it suggested that the atom was not indivisible, as believed earlier. The theory of radioactive decay proposed by Curie helped in validating the existence of subatomic particles.

It was found that by emitting energy and electrons, atoms can undergo changes and lead to the rise of completely new atoms. The discovery of polonium and radium strengthened this theory, as both elements were found to be highly radioactive. Marie Curie is the only person till date who has won two Nobel Prizes in two separate disciplines of science. She was also the first woman to win the prestigious prize as well as the first person to win it twice. Marie Curie played a key role in World War I in terms of healing the wounded.

X-Rays were discovered in by Wilhelm Roentgen, but the X-Ray machines to treat the wounded had a limitation. They were only found in the hospitals, which were far away from the battlefield. Curie recognized that wounded soldiers were best served if operated upon as soon as possible. To solve the problem of providing electricity, Curie installed a dynamo in the mobile car to generate and provide the required electricity.

Apart from inventing mobile radiology units in WW1, Marie Curie also contributed in several other ways. Along with her daughter Irene , she worked in a Casualty Clearing Station and helped in discovering bullets, broken bones and other internal injuries using the X-Ray machines. In the first year of the war itself, she directed the installation of 20 mobile radiology vehicles and another radiology units at field hospitals. She also trained almost women to work as aides in using X-Rays. Her father taught physics and mathematics — subjects Marie would later pursue. Her father was fired by his Russian supervisors for his pro-Polish beliefs, and the family was forced to take in lodgers in order to survive financially.

Marie married Pierre Curie in and together they had two daughters — Irene, born in , and Eve, born in Read the full results of our Women Who Changed the World poll and find out what the experts think here. Growing up in Warsaw in the 19 th century, Marie displayed an interest in science from an early age. She excelled at boarding school and graduated with a gold medal from a gymnasium — a European form of grammar school — for girls in Marie became determined to further her education, and she worked as a governess and a tutor in order to save up the tuition fees. In Marie moved to Paris, where she studied mathematics and physics at the Sorbonne. Despite having very little money and surviving on a poor diet, Marie completed a degree in physics in Just a year later, she received her degree in mathematics.

A year later, the couple were married. She examined whether these properties were found in other forms of matter. Sharing an interest in chemistry and physics, Marie and Pierre worked in collaboration to investigate radioactivity, and in they announced that they had discovered two new chemical elements: polonium and radium. Marie was devastated when, in , Pierre was killed after being knocked over by a horse and cart. In , Marie was presented with her second Nobel Prize, this time in the field of chemistry for her work in isolating radium.

To this day, Marie is the only person to receive two Nobel Prizes in different sciences. Soon after Marie received her second Nobel Prize, two laboratories were constructed at Sorbonne. In one of the laboratories, Marie led a team of researchers analysing radioactivity, while the other laboratory was used to explore possible cancer treatments.
