Greatest discoveries in Physics

Page 2: Some famous physicists

Physics from G. physis, “nature”

Physics is the most fundamental, and the most

quantitative of all sciences

Page 3: Some famous physicists

Physicsis the basis oftechnology.

Page 4: Some famous physicists

Scienceis a way ofthinking.

Page 5: Some famous physicists

Science, technology, and Mathematics are

indispensable partners

Page 6: Some famous physicists

Some of the Greatest Scientists

Page 7: Some famous physicists

Sir Isaac Newton

Page 8: Some famous physicists

Some of the greatest discoveries• Unification of the whole theory

of Mechanics• The discovery that the law of

universal gravitation that govern objects on earth are alike as those that govern the universe

Page 9: Some famous physicists

James Clerk Maxwell

Page 10: Some famous physicists

Some of the greatest discoveries• Proved that :oelectricity and magnetism cannot

exist in isolationolight is produced by oscillating

electric charges• Determined c (299,792,458m/s)

Page 11: Some famous physicists

Albert Einstein

Page 12: Some famous physicists

Some of the greatest discoveries• Formulated the special and general

theory of relativity• Find out that mass can be

converted to energy• Explained the shift in the perihelion

of the planet Mercury• Discovered that light can be bent

by a strong gravitational field

Page 13: Some famous physicists

Louis de Broglie

Page 14: Some famous physicists

Some of the greatest discoveries

Discovered that particles having wavelengths that lead to the wave-particle

dualism for quantum mechanics

Page 15: Some famous physicists

James Prescott Joule

Page 16: Some famous physicists

Some of the greatest discoveries

Worked on the computation of the

mechanical equivalent of heat showing that the

total energy is conserved

Page 17: Some famous physicists

Heinrich Hertz

Page 18: Some famous physicists

Some of the greatest discoveries

Through experimentation, he proved that

electromagnetic waves can travel over some distance

through the air

Page 19: Some famous physicists

Enrico Fermi

Page 20: Some famous physicists

Some of the Greatest scientists

he and his team created the world's first nuclear reactor

in 1942

Page 21: Some famous physicists

Michael Faraday

Page 22: Some famous physicists

Some of the greatest discoveries• one of the pioneers of modern

electromagnetic theory• laid the foundation for the

identification of light as an electromagnetic phenomenon, and led to the employment of electromagnetic waves in communication.

Energy and the Society

Role of energy and interaction among energy, technology, &

society

Page 24: Some famous physicists

Energy, technology, and society• Goal of technology is to control

nature• Continuous search for sources of

energy• Breakthroughs in agriculture• Population growth• Health
