Inventors and Scientific Discoveries Questions
-
Erno Rubik
-
James Gibb
-
George Crum
-
Ruth Handler
D
Correct answer
Explanation
Ruth Handler created the Barbie doll in 1959, naming it after her daughter Barbara. The doll was inspired by a German adult doll called Bild Lilli that Handler had seen during a European trip. Erno Rubik invented the Rubik's cube, and George Crum is associated with potato chips.
-
Theodore Maiman
-
Evangelista Torricelli
-
Italo Marcioni
-
Nicholas Cugnot
B
Correct answer
Explanation
Evangelista Torricelli invented the mercury barometer in 1643, demonstrating that air has weight and creates pressure. His experiment using a mercury-filled glass tube fundamentally changed the understanding of atmospheric pressure. The unit of pressure 'torr' is named in his honor.
-
Henry W Seely
-
Levi Strauss
-
Alessandro Volta
-
Erno Rubik
C
Correct answer
Explanation
Alessandro Volta invented the first true battery, the voltaic pile, around 1800. His invention consisted of alternating zinc and copper discs separated by brine-soaked cardboard, producing steady electrical current. The electrical unit 'volt' is named in recognition of his pioneering work.
-
Montgolfier brothers
-
Nestle
-
James Harrison (Australia)
-
Jacques Cousteau
D
Correct answer
Explanation
Jacques Cousteau and Emile Gagnan co-invented the aqualung in 1943, a self-contained underwater breathing apparatus that revolutionized diving. This device allowed divers to move freely underwater for extended periods. The Montgolfier brothers are famous for inventing the hot air balloon, not diving equipment.
-
Italo Marcioni
-
Don Wetzel
-
Charles Goodyear
-
Leon Battista Alberti
B
Correct answer
Explanation
Don Wetzel led the team that developed the first ATM in 1969 while working at Docutel. The invention transformed banking by enabling 24/7 cash access without visiting a bank branch. The first ATM was installed at a Chemical Bank in New York in 1969.
-
Charles Strite
-
Wilhelm Rontgen
-
Crompton and Co (UK)
-
Kirkpatrick McMillan
D
Correct answer
Explanation
Kirkpatrick McMillan, a Scottish blacksmith, invented the first rear-wheel-driven bicycle around 1839. His design used treadles connected to driving rods to power the rear wheel. Earlier versions like the 'running machine' lacked any mechanism for self-propulsion.
-
Pierre and Ernest Michaux
-
Whitcombe L Judson
-
John Dunlop
-
Thomas Alva Edison
A
Correct answer
Explanation
Pierre and Ernest Michaux developed the first bicycle with pedal-crank drive in the 1860s. Their velocipede design attached pedals directly to the front wheel, creating a more efficient riding experience. John Dunlop invented pneumatic tires, not the crank mechanism.
-
The washing machine
-
The coffee machine
-
The digitally programmable computer
-
None of the above
C
Correct answer
Explanation
Konrad Zuse (1910-1995) was a German civil engineer and computer pioneer who created the first programmable computer, the Z3, in 1941. The Z3 was electromechanical and the first fully automatic digital computer.
-
Arthur Schopenhauer
-
Albert Einstein
-
Georg Ohm
-
Konrad Adenauer
B
Correct answer
Explanation
Albert Einstein (1879-1955) was the German-born physicist who developed the theory of relativity, including both special relativity (1905) and general relativity (1915). He received the Nobel Prize in Physics in 1921. Schopenhauer was a philosopher, Ohm was a physicist known for Ohm's law, and Adenauer was a politician.
-
Isaac Newton
-
Albert Einstein
-
Benjamin Franklin
-
Marie Curie
D
Correct answer
Explanation
Marie Curie, along with her husband Pierre Curie, discovered radium in 1898. She was a pioneering physicist and chemist who conducted extensive research on radioactivity. Isaac Newton worked on gravity and calculus, Albert Einstein developed relativity theory, and Benjamin Franklin studied electricity.
-
Thermometer
-
Barometer
-
Pendulum clock
-
Microscope
A
Correct answer
Explanation
Galileo Galilei is credited with inventing the thermometer in 1593, specifically a rudimentary water thermometer called a thermoscope. While he didn't invent the modern mercury thermometer (that came later), he established the principle. The barometer was invented by Torricelli, pendulum clock by Huygens, and microscope by Janssen/leeuwenhoek.
-
Dynamite
-
Ladders
-
Race cars
-
Parachute
D
Correct answer
Explanation
Early parachute development and testing resulted in numerous fatalities as inventors tested different designs without full understanding of aerodynamics. Many early jumps were unsuccessful. While dynamite, race cars, and ladders can be dangerous, parachutes had the highest death rate during their testing phase.
-
Albert Einstein
-
George Gamow
-
Michael Skube
-
Roger Penrose
B
Correct answer
Explanation
George Gamow, the English-American physicist, was a key proponent of the Big Bang Theory and made significant contributions to cosmology including work on nucleosynthesis. Albert Einstein is associated with relativity, not Big Bang cosmology. Michael Skube and Roger Penrose are not the primary figures associated with the Big Bang theory.
-
A German Physicist
-
Developed the mercury thermometer in 1714
-
Devised temperature scale
-
All of the above
D
Correct answer
Explanation
Gabriel Daniel Fahrenheit (1686-1736) was a German physicist who invented the mercury thermometer in 1714 and devised the temperature scale that bears his name (the Fahrenheit scale). Option D is correct as it encompasses all these facts.
-
Akira Suzuki
-
Ei-ichi Negishi
-
Liu Xiaobo
-
Richard F.Heck
C
Correct answer
Explanation
The 2010 Nobel Prize in Chemistry was awarded to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki for palladium-catalyzed cross couplings in organic synthesis. Liu Xiaobo won the 2010 Nobel Peace Prize, not Chemistry - he was a Chinese human rights activist. The question asks who did NOT win in Chemistry.
