Einstein's Impact on Physics

The video explores Einstein's transformative impact on physics, likening it to Darwin's on biology. It covers the challenges faced by classical physics, key discoveries leading to quantum theory, and Einstein's groundbreaking work in 1905, including special relativity and E=mc2. The video also discusses general relativity, its confirmation in 1919, and Einstein's skepticism towards quantum mechanics. It concludes with Einstein's later life, his legacy, and his views on modernity.

How did Einstein's approach to physics differ from Newton's?

• He turned existing concepts of physics upside down.

• He ignored the concept of time.

• He added a unifying framework similar to Newton.

• He focused solely on the laws of motion.

What was the significance of the Michelson-Morley experiment?

• It proved that atoms are indivisible.

• It failed to detect changes in light speed, challenging the ether theory.

• It showed that light speed changes with Earth's movement.

• It confirmed the existence of ether.

Which discovery did J.J. Thomson make in 1897?

• The concept of quantum mechanics

• The existence of electrons

• The photoelectric effect

• The theory of relativity

What was one of Einstein's major contributions in 1905?

• The theory of general relativity

• The discovery of radioactivity

• The concept of mass-energy equivalence

• The invention of the steam engine

What does the formula E = mc² represent?

• Atoms are indivisible.

• Time is absolute.

• Energy and mass are interchangeable.

• The speed of light is constant.

How did general relativity change the understanding of gravity?

• It suggested gravity does not exist.

• It showed gravity as a distortion in spacetime due to mass.

• It described gravity as a force like light.

• It confirmed that gravity is constant everywhere.

What was Einstein's view on quantum mechanics?

• He ignored quantum mechanics entirely.

• He thought quantum mechanics was complete.

• He believed in a deterministic universe.

• He fully accepted the uncertainty principle.

Why did Einstein move to the United States in 1933?

• He wanted to escape the political situation in Germany.

• He sought better research facilities.

• He was offered a teaching position.

• He was invited to work on the atomic bomb.

What was Einstein's stance on the use of his scientific work?

• He was proud of its military applications.

• He believed it should only be used for energy production.

• He regretted its use for violent purposes.

• He was indifferent to its applications.

What did Einstein believe about the universe despite the horrors of war?

• It was beyond human understanding.

• It was governed by randomness.

• It had a code to be deciphered by science.

• It was chaotic and without meaning.
