Question 1

True or false: Cantor was awarded the Nobel Prize in Mathematics for his work on set theory.

Accepted Answer

False. There is no Nobel Prize in Mathematics; Cantor received the Sylvester Medal from the Royal Society instead.

Question 2

True or false: Cantor suffered from severe depression and spent time in sanatoriums.

Accepted Answer

True. He experienced recurring mental health crises, particularly from the 1880s onward, affecting his later career.

Question 3

True or false: Cantor discovered that there are infinitely many sizes of infinity, known as cardinal numbers.

Accepted Answer

True. He introduced aleph numbers to classify infinite cardinalities, showing one infinity can be larger than another.

Question 4

True or false: Cantor proved that the set of real numbers is larger than the set of natural numbers.

Accepted Answer

True. He used his diagonal argument to show there are uncountably many reals, a groundbreaking proof in set theory.

Question 5

True or false: Cantor was a close friend and frequent collaborator of Albert Einstein.

Accepted Answer

False. No evidence exists of such a friendship; Cantor died in 1918, while Einstein’s major work came later.

Question 6

True or false: Cantor’s ideas were immediately accepted and praised by all leading mathematicians of his time.

Accepted Answer

False. Many, like Kronecker, fiercely opposed his work, calling it a 'pathology' of mathematics.

Question 7

True or false: Cantor originally studied number theory before shifting to set theory.

Accepted Answer

False. His early work was in analysis and trigonometric series, which led him to study infinite sets.

Question 8

True or false: Cantor was the first mathematician to define an infinite set as one that can be put into one-to-one correspondence with a proper subset of itself.

Accepted Answer

True. This definition became a cornerstone of his transfinite set theory, distinguishing infinite from finite sets.
