  3. Hippocrates

  4. Thomas J Watson

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

Charles Darwin, the scientist who formulated the theory of evolution by natural selection, was keenly aware of how precious time is for scientific work. This quote reflects his intense focus on research and his belief that wasting time demonstrates a lack of appreciation for life's opportunities.

  2. Leo Hendrik Baekeland

  3. Roy Plunkett

  4. Henry Ford

B Correct answer
Explanation

Leo Hendrik Baekeland, a Belgian chemist, invented Bakelite in 1907. It was the first synthetic thermosetting plastic. Charles Goodyear worked with rubber vulcanization, Roy Plunkett discovered Teflon, and Henry Ford developed automobile assembly lines - none invented Bakelite.

  1. L.E. Waterman

  2. Laszlo Biro

  3. John Loud

  4. Milton Reynolds

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

Laszlo Biro, a Hungarian journalist, invented the modern ballpoint pen in 1938. His design used a tiny ball bearing that rolled ink onto paper, solving the problem of ink flow that plagued earlier fountain pens. While John Loud patented an earlier version in 1888, it wasn't commercially viable. Biro's invention is why ballpoint pens are still called 'biros' in many countries.

  1. Lewis Waterman

  2. John Jacob Parker

  3. John Scheffer

  4. Peregrin Williamson

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

Lewis Waterman patented the first practical fountain pen in 1884 after his earlier fountain pen leaked during an important contract signing. His invention solved the ink flow problem using a three-channel feed system that regulated ink supply. While earlier fountain pens existed (like Parker's 1884 patent), Waterman's design was the first commercially successful fountain pen.

Multiple choice general knowledge science & technology
  1. Charles Babbage

  2. Swede George

  3. Herman Hollerith

  4. Konrad Zuse

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

Charles Babbage is widely regarded as the 'father of the computer' for designing the Difference Engine (1822) and the Analytical Engine (1837), which introduced concepts like programmability and storage that are fundamental to modern computers. Note: 'Morden' in the question is a typo for 'Modern'.

C Correct answer
Explanation

Dr. Christiaan Barnard performed the world's first human-to-human heart transplant on December 3, 1967 at Groote Schuur Hospital in Cape Town, South Africa. The patient, Louis Washkansky, lived for 18 days after the pioneering surgery.

  1. Alexander Cartwright Jr.

  2. Alex P. Hartford

  3. A bunch of New York City kids

  4. Alex P. Sutherland

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

Alexander Cartwright Jr. is credited with formalizing modern baseball rules in the 1840s, including the diamond-shaped field, foul lines, and three-strike system. While baseball evolved from earlier games, Cartwright's Knickerbocker Rules established the structure of the modern sport. The Abner Doubleday myth was fabricated later.

Multiple choice general knowledge
  1. Benjamin Franklin

  2. Winston Churchill

  3. Jane Austen

  4. Albert Einstein

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

Albert Einstein said this, emphasizing that simplicity requires more intelligence than complexity. Einstein's work in physics sought elegant, simple explanations (like E=mc²) rather than convoluted ones. The quote reflects his philosophical view that genius lies in reducing complexity to fundamental principles.

Multiple choice general knowledge science & technology
  1. Darwin

  2. Lammark

  3. Oparin

  4. Haechel

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

Oparin proposed the theory of chemical evolution of life (primordial soup theory) in 1924, suggesting that organic compounds could form from inorganic precursors through natural chemical reactions. This was a foundational hypothesis for understanding the origin of life on Earth. Darwin focused on natural selection, Lamarck on inheritance of acquired characteristics, and Haeckel on embryology and recapitulation theory.

Multiple choice general knowledge science & technology
  1. newton

  2. Eienstien

  3. Romer

  4. Galelio

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

Ole Rømer was the first to measure the speed of light in 1676 by observing Jupiter's moon Io. He noticed that the timing of Io's eclipses varied depending on Earth's distance from Jupiter, allowing him to calculate light's finite speed. Galileo and Newton contributed to optics but didn't measure light speed. Einstein's work came much later.

Multiple choice general knowledge science & technology
  1. Roentgen:X-ray

  2. Newton: Law of gravitation

  3. Faraday: Diffusion of Gases

  4. Pasteur:Bacteriology

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

Faraday is famous for electromagnetic induction and electrolysis laws, not gas diffusion. The other pairs are correct: Roentgen discovered X-rays, Newton formulated the law of gravitation, and Pasteur founded modern bacteriology.

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 Latham Sholes invented the first practical typewriter in the 1860s, patenting it in 1868. His design became the basis for modern typewriters and the QWERTY keyboard layout. Shockley invented the transistor, Pascal invented the Pascal calculator, and Waterman was a fountain pen pioneer.
