These advancements and many more were based on the work of Marie Curie‚ renowned female physics researcher. To make a list of people that changed the world for the better we need a way to separate the great‚ from the truly amazing. One important factor is that they helped people in their time period‚ and this is made

Jean Daniel Colladon‚ a Swiss physicist‚ discovered how to calculate the speed of sound underwater with the Under-Water Church Bell. Colladon also discovered that sound waves traveled faster underwater than they did in air. In 1880‚ Pierre & his brother‚ Jacques Curie‚ who were both French physicists‚ discovered the Piezo-Electric effect which is the connection between electrical voltage and pressure on crystalline material. This is how modern transducers were created. In 1915‚ Paul Langevin‚ a

In particular‚ the value of exploring unknown information lies in its positive influence on invention and innovation. One of the greatest examples of someone who explored the unknown‚ and changed the world as a result‚ was the great scientist Marie Curie. Marie is credited with the discovery of two periodic elements: Radium‚ most notably‚ and Polium.

It’s a rarity that we should come across a laboratory‚ classroom‚ chemistry textbook or lecture theatre that doesn’t contain a periodic table of the elements. It required the immense research and determination of the scientist Dmitri Mendeleev to show us that all elements followed a natural form and provided us with the first decent periodic table. There are 111 elements recognised today by IUPAC and they are arranged in the periodic table in horizontal groups and vertical periods. The eight groups
