WHO WAS GEORGE WASHINGTON CARVER, HENRY FORD, COPERNICUS, LEONADO DA VINCI, MARIE CURIE, SIR ISAAC NEWTON.....

GOERGE WASHINGTON CARVER; George Washington Carver was born to slave parents but rose to become an important agricultural scientist. He discovered more than 300 different uses for the peanut, and he also did important work with cotton and other crops. Agricultural scientist George Washington Carver developed many different products from peanuts,

including soap, ink, flour, and axle grease.George Washington Carver was born on a farm near Diamond, Missouri, in 1864. His parents were slaves. Carver earned many awards and honors for his work. In 1923, the National Association for the Advancement of Colored People (NAACP) awarded him the Spingarn Medal. In 1935, he was appointed to an important position in the U.S. Department of Agriculture.

HENRY FORD; Henry Ford founded the Ford Motor Company, an automobile manufacturer. In the early 1900s, he made the most popular cars in the United State.Henry Ford set up factories to make cars quickly. As car parts moved along an assembly line, each worker did a specific task, as shown here. The workers did the same task, over and over.The Model T was a simple, sturdy car that most Americans could afford. Between 1908 and 1927, Ford built 15 million Models.

COPERNICUS;          Nicolaus Copernicus was the founder of modern astronomy. Earlier astronomers thought the Sun revolved around Earth, but Copernicus theorized that the opposite was true. By the late 1600s, his theory was widely accepted.

Copernican System

This drawing illustrates the theory of astronomer Nicolaus Copernicus that the Sun is the center of our solar system. Copernicus came up with his theory in the 16th century. Later astronomers proved his ideas were correct.

LEONADO DA VINCI;Leonardo da Vinci was not only one of the greatest painters of all time, but also an architect, sculptor, engineer, and scientist. He worked during the late 1400s and early 1500s mostly in Italy. Da Vinci imagined inventions, like a flying machine, that were not made until hundreds of years later.

Mona Lisa

The Mona Lisa was painted by Italian artist Leonardo da Vinci. The woman’s mysterious smile has made the painting one of the most famous pieces of art in the world.

The Last Supper

Leonardo da Vinci’s mural The Last Supper shows Jesus telling his disciples that one of them will betray him. This mural appears on the wall of a church in Milan, Italy.

MARIE CURIE:

Marie Curie

Marie Curie was a famous scientist who studied radioactivity. In 1903, she became the first woman to win a Nobel Prize, sharing the prize in physics. She won a second Nobel Prize in 1911 in chemistry.

Marie Curie’s Notebooks

French physicist Marie Curie made many important discoveries about radioactivity. Shown here are some of her notebooks detailing her theories.

SIR ISAAC NEWTON;

Isaac Newton

Isaac Newton was one of the greatest scientists of all time. In the late 1600s and early 1700s, he came up with theories about gravity, motion, and light.Newton was born in Woolsthorpe, England, on December 25, 1642. He loved to build mechanical models, but he was not a good student. His mother took him out of school so that he could help run the family farm. Newton did not like farming. He liked to read and study on his own. Newton invented a new kind of mathematics called calculus. Today, scientists and engineers use calculus to solve many kinds of problems.

Newton came up with theories about gravity and motion. He thought that the same force pulling people and apples down to Earth keeps the Moon going around Earth and the planets going around the Sun. He used mathematics to prove his theories.

Newton used a prism, a piece of glass with many sides, to study light. He found that sunlight is made up of every color in the rainbow.
