Inventors and Scientific Discoveries Questions
-
Mary anderson
-
Patricia Billings
-
Katherine Blodgett
-
Marie Curie
A
Correct answer
Explanation
Mary Anderson was granted the first patent for an automatic car window cleaning device (windshield wipers) in 1903. The question uses 'Windshield' as shorthand for the wiper system. Marie Curie and Katherine Blodgett worked in physics and chemistry.
-
Valerie Thomas
-
Amanda Theodosia Jones
-
Bette Nesmith Graham
-
Patricia Billings
D
Correct answer
Explanation
Patricia Billings, a sculptor, invented Geobond, a non-toxic, fireproof building material, while trying to find a durable plaster for her art. Valerie Thomas and Bette Nesmith Graham are famous for unrelated inventions.
-
Sally Fox
-
Katherine Blodgett
-
Josephine Garis Cochran
-
Valerie Thomas
B
Correct answer
Explanation
Katherine Blodgett was the first woman to earn a PhD in physics from Cambridge and invented 'invisible' or non-reflecting glass by adding monomolecular film coatings to surfaces. This technology is essential for cameras and eyeglasses.
-
Randi Altschul
-
Lillian Gilbreth
-
Mary Jacob
-
Marie Curie
D
Correct answer
Explanation
Marie Curie is renowned for her pioneering research on radioactivity and her development of mobile X-ray units during WWI. While Wilhelm Röntgen discovered X-rays, Curie's work was fundamental to the technology's medical application.
-
Mary anderson
-
Mary Kies
-
Bette Nesmith Graham
-
Margaret Knight
C
Correct answer
Explanation
Bette Nesmith Graham, a secretary, invented 'Mistake Out' (later Liquid Paper) in her kitchen to correct typing errors. Mary Anderson invented windshield wipers, and Margaret Knight invented the flat-bottomed paper bag machine.
-
Ann Moore
-
Katherine Blodgett
-
Alice Parker
-
Amanda Theodosia Jones
D
Correct answer
Explanation
Amanda Theodosia Jones, an American inventor, patented the vacuum-packed canning process in 1873. Her innovation involved using a vacuum to remove air from containers before sealing them, which significantly improved food preservation by reducing bacterial growth. This technique laid groundwork for modern vacuum-sealing food storage methods. Katherine Blodgett invented non-reflective glass, while Alice Parker invented a gas-powered heating furnace.
-
Valerie Thomas
-
Mary anderson
-
Mary Walton
-
Carol Wior
A
Correct answer
Explanation
Valerie Thomas, a NASA scientist, invented the Illusion Transmitter in 1980. This optical device uses concave mirrors to create 3D optical illusions, capturing an image at one point and projecting it as a three-dimensional illusion at another point. Her invention received a NASA patent and has applications in medical imaging, television, and video technology. Mary Walton invented pollution-reduction devices, Mary Anderson invented windshield wipers, and Carol Wior invented slimming swimwear.
-
Henry Labouisse
-
Jan Tinbergen
-
Linus Pauling
-
Manne Siegbahn
C
Correct answer
Explanation
Linus Pauling indeed received two unshared Nobel Prizes - Chemistry in 1954 for work on chemical bonds, and Peace in 1962 for nuclear disarmament advocacy. No other person has achieved two unshared prizes. Marie Curie won two prizes but shared one.
-
Gordon Moore
-
William Shockley
-
Fred Terman
-
Robert Noyce
-
John L. Baird
-
Fred Terman
-
Samuel Morse
-
Marconi
B
Correct answer
Explanation
Frederick Terman's 'Radio Engineering' (1932) was the foundational textbook that shaped radio and electronics engineering education. Terman, a Stanford professor, mentored many Silicon Valley pioneers including William Hewlett and David Packard. His work established Stanford as a center for electronics innovation and helped launch the semiconductor industry in the region.
-
Max Muller
-
Bertrand Russel
-
Albert Einstein
-
FD Roosevelt
C
Correct answer
Explanation
This quote about India's contribution to mathematics (particularly the decimal system and zero) is widely attributed to Albert Einstein. He praised Indian mathematical innovations as foundational to scientific progress. This attribution appears in many sources.
-
Max Muller
-
Bertrand Russel
-
Albert Einstein
-
FD Roosevelt
C
Correct answer
Explanation
Einstein praised India's mathematical contributions, particularly the decimal system and concept of zero, which are foundational to modern mathematics and scientific progress. This quote acknowledges that without these numerical innovations, advanced scientific discoveries would not have been possible.
-
Joseph Priestly
-
Isaac Newton
-
Carlo Collodi
-
John Steinbeck
A
Correct answer
Explanation
Joseph Priestley discovered oxygen in 1774 by heating mercuric oxide. He published his findings first, though Carl Wilhelm Scheele had also discovered it independently but did not publish until later. The other options (Newton, Collodi, Steinbeck) are not associated with chemical discoveries.
-
Arabians
-
Europeans
-
Asians
-
mayans
-
Aryabhatta
-
Einstein
-
Bhaskaracharya
-
Newton
A
Correct answer
Explanation
Zero as a numerical concept emerged in ancient India. Aryabhata (5th century CE) used a place-value system with a zero placeholder, though Brahmagupta later formalized zero's arithmetic rules. Einstein and Newton worked millennia after zero's development.
