Einstein: un famoso científico

Ingles:

Einstein: a famous scientist

In 1905, a 26-year-old patent clerk named Albert Einstein changed the way we understand our universe.

Providing very important information for the development of science through time, Einstein first studies focused on the nature of light. He believed that light consists of small packets of energy, called photons. When these photos are of the right energy level, or color, they can dislodge electrons from the atoms of some metals. This interaction causes an electric current to flow in the material. This discovery called the photoelectric effect is the basis of modern inventions such as television camera tubes, solar power cells, and photographic light meters. The photoelectric effect helped Einstein win the 1921 Nobel Prize for Physics, because his way of explaining light helped develop a new field of science called Quantum theory. This theory laid the foundation for other applications, including nuclear science, electronics, and nanotechnology.

Einstein also proposed his famous theory of relativity, disagreeing with a fundamental belief of scientists, like Isaac Newton, who assured that the measurement of time is a constant throughout the universe. Einstein´s Theory maintained that the speed of light, not time, is constant across the universe. These Revolutionary scientist´s ideas, in modern physics have launched many of the life-altering inventions produced during the past 100 years.
