¢
a German-American physicist¢ Born on: March 26th, 1876
¢ Death: April 18, 1955
¢ did not speak clearly until he was 12 and his parents and teachers both thought that he was very slow and unable to learn.
¢ Practical jokes were one of his favourite activities.
¢ Learned how to play the violin and was given a place in the London Symphony Orchestra.
— Some say he was so talented that he could have become the finest musician in the world
¢
He came to New York City, where he became one of the most successful comics.The name given to him was “Fuzz Ball”, and one of his trademarks was sticking his tongue out at audiences.
¢ he helped the government develop the Atom Bomb and accomplished his dream of making big explosions.
¢ He also proved The Theory of Relativity with the formula “E= mc2.
¢ won a Nobel Prize in 1921 for physics
¢ After this honour, he referred to himself as the “Superstar of Science”.
Galileo Galilei
¢
Italian astronomer and physicist
¢ Born on: February 15, 1564
¢ Career: Physicist, Mathematician, Astronomer, Philosopher
¢ Death: January 8, 1642
¢ Galileo, known as the ‘Father of Modern Physics’ or ‘Father of Modern Science’,
Astronomy
¢ In 1608, Galileo, made a telescope with about 3x magnification.
— improved the telescope, to make one with up to about 32x magnification, which is now known as terrestrial telescope, or spyglass.
¢ discovered the four moons of Jupiter, which he named as the ‘Medicean stars’.
¢ observed the phases of Venus and proved that it orbited the Sun.
¢ first European to observe and recognize sunspots.
¢ Physics
¢ Claimed that a pendulum's swings always take the same amount of time
¢ Described an experimental method to measure the speed of light
¢ Presented a physical theory to account for tides, based on the motion of the Earth

Sir Isaac Newton
¢ British scientist
¢ Born on: 1642
¢ Death: 1727
¢ was born just a short time after the death of Galileo
¢ thought the universe worked like a machine and that a few simple laws governed it.
¢ Like Galileo, he realized that mathematics was the way to explain and prove those laws.
¢ He worked out the basic laws of motion and gravity.
¢ He also showed that sunlight is made up of all the colors of the rainbow.
¢ He invented the branch of mathematics called calculus, but he kept this discovery quiet
¢ He also used his laws to show that the planets revolve around the suns in orbits that are oval, not round.

Newton’s Laws
Isaac Newton used three laws to explain the way objects move called Newton’s Laws.
¢ The First Law states that an object that is not being pushed or pulled by some force will stay still, or will keep moving in a straight line at a steady speed.
— It is easy to understand that a bike will not move unless something pushes or pulls it. It is harder to understand that an object will continue to move without help. Think of the bike again. If someone is riding a bike and jumps off before the bike is stopped what happens? The bike continues on until it falls over. The tendency of an object to remain still, or keep moving in a straight line at a steady speed is called inertia.
¢ The Second Law explains how a force acts on an object. An object accelerates in the direction the force is moving it.
— If someone gets on a bike and pushes the pedals forward the bike will begin to move. If someone gives the bike a push from behind, the bike will speed up. If the rider pushes back on the pedals the bike will slow down. If the rider turns the handlebars, the bike will change direction.
¢ The Third Law states that if an object is pushed or pulled, it will push or pull equally in the opposite direction.
— If someone lifts a heavy box, they use force to push it up. The box is heavy because it is producing an equal force downward on the lifter’s arms. The weight is transferred through the lifter’s legs to the floor. The floor presses upward with an equal force. If the floor pushed back with less force, the person lifting the box would fall through the floor. If it pushed back with more force the lifter would fly into the air.
C. V. Raman
Born: November 7, 1888
Died: November 21, 1970
Achievements: first Indian scholar who studied wholly in India received the Nobel Prize.
¢ His full name was Chandrasekhara Venkata Raman.
¢ C.V. Raman won the Nobel Prize for Physics in 1930 for his work on scattering of light.
— The discovery was later christened as "Raman Effect".
¢ Raman joined the Indian Finance Department in 1907. After his office hours, he carried out his experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta. He carried out research in acoustics and optics.
¢ In 1917, Raman was offered the position of Sir Taraknath Palit Professorship of Physics at Calcutta University. He stayed there for the next fifteen years.
¢ He was elected to the Royal Society of London in 1924 and the British made him a knight of the British Empire in 1929.
