Multiple choice general knowledge science & technology

Einstein could not grasp which of these elementary school subjects, leading him into a mini depression?

  1. Geometry

  2. Science

  3. Greek

  4. Mathematics

C Correct answer
Explanation

Einstein struggled with Greek due to the authoritarian teaching methods and rote memorization required, which led to his mini-depression. He excelled at mathematics and science, and geometry was actually one of his favorite subjects where he thrived.

In 1905, the final jigsaw pieces of the special theory of relativity came to Einstein where?

  1. While reading David Hume

  2. Lunchbreak at the patent office

  3. In his sleep

  4. While hiking in the Alps

C Correct answer
Explanation

According to biographical accounts, Einstein reported that the final insights for the special theory of relativity came to him in a dream or during sleep. This anecdote highlights how unconscious processing often contributes to creative scientific breakthroughs.

Multiple choice general knowledge science & technology

1905 was a very busy year for Einstein. 'Relativity' was his fourth paper. The fifth that year was on the photoelectric effect. By applying this great scientists' quantum theory of light, Einstein helped to establish quantum mechanics. Who was this great German scientist and idol to Einstein?

  1. Philip Lenard

  2. Max Planck

  3. Marie Curie

  4. Max von Laue

B Correct answer
Explanation

Max Planck was the German physicist who originated quantum theory with his discovery of energy quanta in 1900. Einstein applied Planck's quantum concept to explain the photoelectric effect in his 1905 paper, which helped establish quantum mechanics as a fundamental field of physics.

Multiple choice general knowledge science & technology

Einstein summed up the special theory of relativity in a magazine review a few years later with the now legendary equation E=mc2. How does this translate?

  1. Energy = atomic mass squared

  2. Energy = mass multiplied by velocity squared

  3. Energy = mass multiplied by time squared

  4. Energy = mass multiplied by the speed of light squared
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The equation E=mc² means Energy equals mass multiplied by the speed of light squared (c represents the constant speed of light, approximately 3×10⁸ m/s). This fundamental relationship shows that mass and energy are interchangeable and a small amount of mass can be converted into an enormous amount of energy.

Multiple choice general knowledge science & technology

What did Einstein win a Nobel Prize for in 1922, 17 years after relativity was first published?

  1. Unified Field Theory of Relativity

  2. Special Theory of Relativity

  3. Services to Theoretical Physics

  4. General Theory of Relativity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Einstein received the 1922 Nobel Prize in Physics 'for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect.' The Nobel Committee specifically cited the photoelectric effect rather than relativity, which was still controversial at the time.

Multiple choice general knowledge science & technology

Einstein first visited the United States of America in April, 1921. What was the purpose for the visit?

  1. To leave Germany due to Nazi torment

  2. To support the World Zionist Organisation

  3. To lecture on the University circuit

  4. To witness an experiment by Robert Millikan on redshifts
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Einstein's first visit to the United States in April 1921 was primarily to support the World Zionist Organisation and help raise funds for the establishment of a Hebrew University in Jerusalem. He was an outspoken supporter of the Zionist cause and Jewish cultural renewal.

Multiple choice general knowledge science & technology

What did Edgar Hoover suspect so strongly, that he committed thousands of FBI man-hours in unsuccessfully trying to convict Einstein?

  1. Einstein was a communist

  2. Einstein had conspired against the US government

  3. Einstein was smuggling fission secrets to the Soviet

  4. Einstein was a fraud
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

J. Edgar Hoover, FBI Director, was convinced that Einstein was a communist and devoted extensive FBI resources to investigating him without ever finding evidence to support his suspicions. Einstein's pacifist views, civil rights advocacy, and association with leftist organizations made Hoover suspicious during the anti-communist era.

Multiple choice general knowledge science & technology

One of the reasons it took 30 years for the majority of scientists to support relativity was that it dispelled the mythical existence of the ether. Ether was described as an infinite, jelly like substance, which was the medium for the propagation of electromagnetic waves.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The statement is historically accurate. Einstein's special relativity (1905) challenged the widely-held belief in luminiferous ether as the medium for electromagnetic wave propagation. The scientific community's resistance to abandoning the ether concept was indeed one factor that delayed relativity's widespread acceptance for several decades.

Multiple choice general knowledge science & technology

What is the minimum memory requirements for Microsoft Windows XP?

  1. 32MB

  2. 64MB

  3. 128MB

  4. 256MB
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The correct answer is B (64MB) because Microsoft officially specified 64MB RAM as the minimum requirement for Windows XP, though 128MB or more was recommended for acceptable performance. Windows XP was more resource-intensive than earlier Windows versions like Windows 98 (which could run on 32MB).
