Famous Personalities and Discoveries Questions
-
Developed the telescope
-
Discovered 4 satellites of Jupiter
-
Discovered that the movement of the pendulum produces a regular time measurement
-
All are correct
D
Correct answer
Explanation
Galileo made multiple significant contributions to astronomy and science. He discovered four moons of Jupiter, developed telescope improvements, and studied pendulum motion. The question asks which statement describes him, and since all listed achievements (A, B, C) are correct, option D 'All are correct' is the right choice.
-
Jean Bernard Léon Foucault
-
Benjamin Franklin
-
Samuel Fox
-
Philo Taylor Farnsworth
C
Correct answer
Explanation
Samuel Fox, a British inventor, developed the modern steel-frame umbrella in the 1850s. His 'Fox Frame' umbrellas used a collapsible steel rib design that made them more durable and portable. Foucault worked with pendulums, Franklin with electricity, and Farnsworth with television.

C. A Angel
-
Van der Waals
-
Albert Einstein
-
I Newton
C
Correct answer
Explanation
Albert Einstein published the theory of General Relativity in 1915, describing gravity as the curvature of spacetime caused by mass and energy. This revolutionary theory replaced Newton's gravitational theory and predicted phenomena like gravitational lensing and black holes.
-
Albert Einstein
-
Conrad Rontgen
-
Galileo
-
Edwin Hubble
D
Correct answer
Explanation
Edwin Hubble was the first to observe that the universe is expanding and galaxies are receding from each other. This became known as Hubble's Law (1929), showing that galaxies are moving away from us at speeds proportional to their distance - a fundamental discovery in cosmology.
-
Edwin Hubble
-
Newton
-
Archimedes
-
Einstein
A
Correct answer
Explanation
Edwin Hubble first observed that the universe is expanding and galaxies are receding from each other (Hubble's Law, 1929). This is a duplicate of question 46933 with shuffled options. Option A correctly identifies Hubble.
-
JAMES CROMWELL MATHUR
-
STEPHEN HAWKINGS
-
MAX VON PLANCK
-
WILLIAM LAMBERT
B
Correct answer
Explanation
Stephen Hawking (though spelled 'Hawking' not 'Hawkins') is indeed the theoretical physicist described in the question. He was awarded the Presidential Medal of Freedom in 2009 by Barack Obama, was born in England (Oxford, 1942), did his BA at Oxford University, and his principal fields are theoretical cosmology and quantum gravity. Hawking is one of the most famous physicists in history, known for his work on black holes and his book 'A Brief History of Time'. The other options are fictional or misnamed physicists.

-
Mickey Sony
-
Mickey Rooney
-
Mickey Sooney
-
Mickey Rony
B
Correct answer
Explanation
Mickey Mouse was NOT named after Mickey Rooney. This is a common myth. Walt Disney named the character Mickey Mouse, and there's no evidence it was named after the famous child actor Mickey Rooney. The name was reportedly suggested by Walt's wife Lillian from 'Mortimer' to 'Mickey.'
-
Jack Tont Woods
-
Nicolos Tont Woods
-
Joe Tont Woods
-
Eldrick Tont Woods
D
Correct answer
Explanation
Tiger Woods' birth name is Eldrick Tont Woods. The nickname 'Tiger' was given by his father in honor of a fallen soldier friend.
-
roger federer
-
tiger woods
-
kobe bryant
-
lance amstrong
B
Correct answer
Explanation
Tiger Woods was born Eldrick Tont Woods, with "Tont" being a traditional Thai name from his mother's heritage. He won his first major championship at age 21, making him the youngest to win a Grand Slam event at the time. He was indeed the highest-paid athlete in 2008. His nickname "Tiger" was given by a Vietnamese soldier friend of his father, Earl Woods. The other athletes - Federer, Bryant, Armstrong - don't match these biographical details.
-
Rene Decartes
-
Karl Gauss
-
Archimedes
-
Blaise Pascal
-
Evartiste Galois
E
Correct answer
Explanation
Évariste Galois is credited with founding group theory, making fundamental contributions to abstract algebra before his death at age 20 in 1832. Despite the typo in the option ("Evartiste" instead of "Évariste"), this is the correct answer. Descartes founded analytic geometry and Cartesian coordinate systems, Gauss made contributions across multiple fields, Archimedes pioneered ancient mathematics and physics, and Pascal developed probability theory and Pascal's triangle - none founded group theory.
-
Alois Hitler
-
Altis Hitler
-
Leopold Hitler
-
William Patrick Hitler
A
Correct answer
Explanation
Alois Hitler (1837-1903) was Adolf Hitler's father, an Austrian customs official. He was born Alois Schicklgruber and changed his surname to Hitler in 1876.

The Andromeda Strain is a science fiction techno-thriller novel by Michael Crichton, published in 1969. It tells the story of a deadly extraterrestrial microorganism and the team of scientists working to contain it. The novel established Crichton's reputation for combining science with suspense and was adapted into a film. Crichton is famous for Jurassic Park, Sphere, and other science-based thrillers.
-
De Broglie
-
Heisenberg
-
Bohr
-
Einstein
B
Correct answer
Explanation
The uncertainty principle, fundamental to quantum mechanics, states that certain pairs of physical properties cannot both be precisely determined. Werner Heisenberg first formulated this principle in 1927, revolutionizing physics. De Broglie proposed wave-particle duality. Bohr developed atomic theory. Einstein developed relativity. Only Heisenberg is correctly associated with the uncertainty principle.
