Multiple choice general knowledge science & technology
  1. Mary anderson

  2. Patricia Billings

  3. Katherine Blodgett

  4. Marie Curie

Reveal answer Fill a bubble to check yourself
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.

  4. Valerie Thomas

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge science & technology
  1. Randi Altschul

  2. Lillian Gilbreth

  3. Mary Jacob

  4. Marie Curie

Reveal answer Fill a bubble to check yourself
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.

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.

Multiple choice general knowledge science & technology
  1. Ann Moore

  2. Katherine Blodgett

  3. Alice Parker

  4. Amanda Theodosia Jones

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge science & technology
  1. Valerie Thomas

  2. Mary anderson

  3. Mary Walton

  4. Carol Wior

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge science & technology
  1. John L. Baird

  2. Fred Terman

  3. Samuel Morse

  4. Marconi

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge
  1. Max Muller

  2. Bertrand Russel

  3. Albert Einstein

  4. FD Roosevelt

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge history
  1. Max Muller

  2. Bertrand Russel

  3. Albert Einstein

  4. FD Roosevelt

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge
  1. Joseph Priestly

  2. Isaac Newton

  3. Carlo Collodi

  4. John Steinbeck

Reveal answer Fill a bubble to check yourself
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.

Multiple choice general knowledge
  1. Aryabhatta

  2. Einstein

  3. Bhaskaracharya

  4. Newton

Reveal answer Fill a bubble to check yourself
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.
