Ramanujan's Number Mini Quiz

Test your knowledge with these top questions!

Question 1

Mathematician Srinivasa Ramanujan famously noted that 1729 is the smallest number to have what trait?

The number 1729 can be expressed as 1 cubed plus 12 cubed, and also as 9 cubed plus 10 cubed. No smaller positive integer shares this unique mathematical property.

Question 2

British mathematician G.H. Hardy famously noticed the number 1729 on the side of what vehicle?

Hardy rode in this specific cab while visiting a hospital in London. Because of this legendary anecdote, numbers with this cubic property are now called taxicab numbers.

Question 3

Mathematicians study the unique traits of integers like Ramanujan's number 1729 in what specific field?

Number theory is a branch of pure mathematics dedicated entirely to the properties of integers. It focuses on whole numbers, unlike calculus which studies continuous change.

Question 4

British mathematician G.H. Hardy originally dismissed the famous taxicab number 1729 as what?

Hardy remarked that 1729 seemed uninteresting and hoped it was not a bad omen. His peer immediately corrected him by pointing out the hidden mathematical beauty of the integer.
