Gottfried von Leibniz and Emilie du Châtelet

# data[].attributes.body
Nationality: German and French

Concept: The energy of an object is a function of the square of its peed.

Experiment: Chatelet analyzed experiments where brass balls were dropped in clay measuring their impacts demonstrated that an objects energy is a function of its velocity squared.

Time Period: 1772

Challenges Faces: No one believed her because everyone wanted newton to be right.

Nationality: French

Concept: Mass is never gained or lossed but transferred into different forms.

Experiment: Turn water into gas then back to water and get the exact amount of water started with.

Time Period: 1789

Challenges Faced: People hated his ideas and people didn't believe hm.

Nationality: English

Concept: energy does not move a straight line.

Experiment: he used a static magnet move a wire.

Time Period: 1812

Challenges Faced: he had some setbacks but eventually came over them for example it took him awhile to become scientist.

Nationality: English

Concept: That light was a form of electromagnetic wave

Experiment: When electricity flows song a wire it creates a little magnetism and as it moves it creates electricity. So electricity and magnetism are woven together but the electricity producing magnetism and magnetism producing electricity can only happen when it is moving at the speed of light.

Time Period:1846

Challenges Faces: no one believed that he was right .
