Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Linus Pauling won the Nobel Prize in Chemistry in 1954 for his work on chemical bonding and the Peace Prize in 1962 for his activism against nuclear testing. He is one of only four individuals to win two Nobel Prizes and the only one to win two unshared prizes.

Multiple choice general knowledge
  1. Issac Newton

  2. Enrico Fermi

  3. Carl David Anders

  4. Charles Augustine Coulomb

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Charles Augustine Coulomb formulated Coulomb's Law, which describes the electrostatic force between charged particles. This fundamental law states that the force is directly proportional to the product of charges and inversely proportional to the square of distance between them (F = kq1q2/r²).

Multiple choice general knowledge
  1. Robert Oppenheimer

  2. Alexander Fleming

  3. Richard

  4. Merry Cury

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

J. Robert Oppenheimer was the scientific director of the Manhattan Project, which developed the first atomic bombs during WWII. He is often called 'the father of the atomic bomb.' Alexander Fleming discovered penicillin, Marie Curie studied radioactivity (misspelled here as Merry Cury), and Richard is too vague to identify.

  3. Bjarne Stroustrup

  4. Rasmus Lerdorf

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dennis Ritchie created C at Bell Labs in the early 1970s for Unix development. James Gosling created Java, Bjarne Stroustrup created C++, and Rasmus Lerdorf created PHP.

Multiple choice general knowledge science & technology
  1. T. H. Huxley

  2. Leeuwenhoek

  3. Rudolf Virchow

  4. J. C. Bose

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

T.H. Huxley famously described protoplasm as the 'physical basis of life' in the 19th century, emphasizing its fundamental role in living organisms. Leeuwenhoek was an early microscopist who discovered microorganisms, while Virchow is known for 'omnis cellula e cellula' (all cells come from cells). J.C. Bose contributed to plant physiology but did not work on protoplasm theory.

Multiple choice general knowledge science & technology

  2. X-ray

  3. Streptomycin

  4. Telephone

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alexander Fleming discovered penicillin in 1928 from the Penicillium mold, revolutionizing medicine with the first antibiotic. X-rays were discovered by Wilhelm Roentgen, streptomycin was discovered by Selman Waksman, and the telephone was invented by Alexander Graham Bell.

Multiple choice general knowledge science & technology
  1. Shockley

  2. Pascal

  3. Sholes

  4. Waterman

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Christopher Sholes invented the first practical typewriter in 1867, which later evolved into the modern QWERTY keyboard. William Austin Burt had created an earlier typewriter prototype in 1829, but Sholes' version was commercially successful. Shockley worked on transistors, Pascal on calculating machines, and Waterman on fountain pens.
