1905 and 1916 Einstein introduced his theories of relativity

Einstein argued that measurements of space and time are not absolute but are determined by many factors...

Einstein’s theories of relativity were accepted by many scientists

Einstein’s theories led to many new discoveries such as the atomic fission

Received the 1921 Nobel Prize in physics

Curie experimented with an atomic process called radioactivity

Curie and others discovered that atoms of certain elements spontaneously release charged particles

Studying radioactivity further, it was discovered that it can change atoms of one element into atoms of another

Curie’s contributions to such findings proved that atoms are not solid and invisible

Curie’s theories also led to the discovery of the atomic fission
