Inventors and Scientific Discoveries Questions

Multiple choice general knowledge science & technology
  1. Robert Hooke

  2. Robert Koch

  3. Robert Brown

  4. Robert Clive

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

Robert Koch pioneered the technique of growing bacteria in pure culture on solid media in the late 19th century, which was revolutionary for microbiology. While Robert Hooke first observed microorganisms in the 17th century, Koch's work established systematic methods for isolating and growing specific bacterial species, forming the basis of germ theory.

Multiple choice general knowledge science & technology
  1. Selman Waksman

  2. Alexander Fleming

  3. Abelardo Aguilar

  4. Beecham scientists

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

Alexander Fleming discovered penicillin in 1928, which is widely recognized as the first antibiotic. Selman Waksman coined the term antibiotic but discovered streptomycin later. Abelardo Aguilar discovered erythromycin, and Beecham scientists developed amoxicillin, both after penicillin.

Multiple choice general knowledge science & technology
  1. James Watson, Francis Crick

  2. James Watson, Maurice Wilkins

  3. Peter Mitchell, Maurice Wilkins

  4. James Watson, Theodore Schwann

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

James Watson and Francis Crick formulated the double helix structure of DNA in 1953, building on X-ray diffraction data from Rosalind Franklin and Maurice Wilkins. This discovery revolutionized our understanding of genetic information storage.

Multiple choice general knowledge science & technology
  1. Robert Clive

  2. Robert Koch

  3. Robert Hooke

  4. Robert Brown

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

Robert Koch was the first to successfully grow microorganisms in pure culture using solid media, developing Koch's postulates. Robert Hooke observed microorganisms but did not grow them, Robert Brown discovered cell nuclei, and Robert Clive was a colonial administrator.

Multiple choice general knowledge science & technology
  1. Gregor Johann Mendel

  2. Thomas Hunt Morgan

  3. Hunt Thomas Morgan

  4. Johann Gregor Mendel

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

Gregor Johann Mendel established that traits are inherited through genes through his pea plant experiments, founding modern genetics. Thomas Hunt Morgan later confirmed this with fruit flies, showing genes are on chromosomes.

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

  2. G.J. Mendel

  3. Eugene Simpson

  4. Charles Darwin

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

T.H. Morgan won the Nobel Prize in 1933 for his work on genetics using the fruit fly (Drosophila melanogarium), demonstrating that genes are located on chromosomes. G.J. Mendel founded genetics earlier, Eugene Simpson is not a known geneticist, and Charles Darwin proposed natural selection.

Multiple choice general knowledge history

  3. Adam

  4. Allen

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

Thomas Alva Edison is the full name of the famous American inventor. 'Alva' is his middle name. Edison is one of the most prolific inventors in history, holding over 1,000 patents including the phonograph and the practical electric light bulb.

Multiple choice general knowledge
  1. Stephen Hawkin

  2. Charles Darwin

  3. Alexander Fleming

  4. Louis Pasteur

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

Charles Darwin wrote 'On the Origin of Species' (full title: 'On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life') published in 1859. This revolutionary book presented Darwin's scientific theory that populations evolve over generations through natural selection. It forms the foundation of evolutionary biology. Stephen Hawking is a physicist, Alexander Fleming discovered penicillin, and Louis Pasteur contributed to germ theory and vaccination.

Multiple choice general knowledge
  1. Shockley

  2. Pascal

  3. Sholes

  4. Waterman

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

Christopher Latham Sholes, along with partners Samuel Soule and Carlos Glidden, invented the first practical typewriter in 1867. Sholes' design, known as the Sholes and Glidden typewriter, was commercially produced by Remington and Company. The QWERTY keyboard layout, still used today, was also developed by Sholes to prevent jamming of commonly used letter combinations. Shockley worked on transistors, Pascal invented the mechanical calculator, and Waterman is associated with fountain pens.

Multiple choice general knowledge science & technology
  1. John Graham

  2. Charles Babbage

  3. Wilhelm Schickard

  4. none of these

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

Charles Babbage is widely regarded as the Father of Computers for designing the Difference Engine and Analytical Engine in the 19th century, which laid the theoretical groundwork for modern computers. John Graham and Wilhelm Schickard were not primarily known as computer pioneers, and 'none of these' is incorrect since Babbage is the correct answer.

Multiple choice general knowledge
  1. Telescope

  2. Stethoscope

  3. Compass

  4. Periscope

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

In 'Twenty Thousand Leagues Under the Sea,' Jules Verne described Captain Nemo using a periscope on the Nautilus submarine. When periscopes were actually invented decades later for submarine warfare, the original inventor was denied a patent, as the concept was already published in Verne's fiction.
