QUESTION 4

X was invented independently by the Babylonians, Mayans and Indians(although some researchers say the Indian number system was influenced by Babylonians).

ANSWER

Zero

QUESTION 5*

X is a sequence of six 9s that begins at the 762nd decimal place of the decimal representation of π. It is named after physicist Y, who once stated during a lecture he would like to memorize the digits of π until that point, so he could recite them and quip "nine nine nine nine nine nine and so on", suggesting, in a tongue-in-cheek manner, that π is rational.

ID X.You might know X for a series. Or in fact, many series following the same pattern.

ANSWER

Brook Taylor

QUESTION 9

X was an Indian Mathematician who was the first to write numbers in the Hindu decimal system, with a circle for zero. X also gave a unique approximation of the sine function in his commentary on Aryabhatta's work, Aryabhatiyabhasya, which is the oldest known prose work in Sanskrit on mathematics and astronomy. There is also a low-orbit satellite named after him.ID X.

ANSWER

Bhaskara-I

QUESTION 10X was born on 1 April 1776, in Paris, France, in a house on Rue Saint-Denis. When she was 13, the Bastille fell and she was forced to say indoors. Thus she turned to her father's library, and was intrigued by geometry. Thus began her affair with mathematics. She was known to hide candlesticks in her shoes to enable her to study at night.She adopted a male pseudonym, Monsieur Le Blanc, to enable her to send notes to Lagrange. Upon meeting her, Lagrange did not shun her, but supported her openly. She won a prize for her work in elasticity. However, she did her best work in number theory, where a theorem is named after her. This theorem is based on solutions to Fermat's Last Theorem.ID X.

ANSWER

Sophie Germain

QUESTION 11

The X is a shorthand version for a particular form of cross-multiplication. It was often taught to students in the 19th century by rote. This rule was highly useful for solving problems such as, ""If 4 Yards of Cloth cost 12 Shillings, what will 6 Yards cost at that Rate?"Charles Darwin said about X, "I have no faith in anything short of actual measurement and the X.”The term X is also used in C++, writing and in economics.ID X.

ANSWER

Rule of Three

QUESTION 12

X is a Babylonian clay tablet, notable as containing an example of Babylonian mathematics. This tablet, believed to have been written about 1800 BC, has a table of four columns and 15 rows of numbers in the cuneiform script of the period.This table lists what are now called Pythagorean triples, i.e., integers a, b, c satisfying a^2+b^2=c^2Id X.

ANSWER

Plimpton-322

QUESTION 13

X was discovered by a Polish mathematician, as he was doodling at what he described as a long and boring conference. He wrote down a rectangular grid of numbers and then spiralled out, circling the prime numbers. He noticed a pattern among the prime numbers. It seemed that the prime numbers lay on alternating diagonals. However, what was surprising was the tendency of prime numbers to lie more on some diagonals than on others.

ID X.

ANSWER

Ulam Spiral

QUESTION 14

X means a group of four things. The term X dates to the 14th century in English. The word appears in the King James Bible (Acts 12:4), which refers to "four Xs of soldiers."The term was popularised by William Rowan Hamilton, who used the word to refer to a four dimensional object with one real part and three imaginary parts.Hamilton dedicated the last twenty years of his life to Xs, and his magnum opus was called Lectures on Xs.ID X.

ANSWER

QUARTERNIONS

QUESTION 15

X is the notation commonly used in arithmetic and logical formulae and statements. It is characterised by the use of operators between operands.It is more difficult to parse, or analyse, by computers. But it is still used in programming languages due to familiarity. In fact, everyone in this room is familiar with this notation.ID X.

ANSWER

Infix Notation

QUESTION 16*Named after a Swedish Mathematician, X is one of the earliest known ______ curves. X can be constructed by starting with an equilateral triangle, then recursively altering each line segment as follows:

1. Divide the line segment into three segments of equal length.2. Draw an equilateral triangle that has the middle segment from step 1 as its base and points outward.3. Remove the line segment that is the base of the triangle from step 2.X is the limit approached as the above steps are followed again and again.It is thus a figure with infinite perimeter but finite area.ID X.The Mathematician in question has a common surname with two American brothers who are billionaires and heavy weight businessmen.

ANSWER

Koch Snowflake

QUESTION 17

X was created by the Nicolas Bourbaki group of mathematicians and appears in the margins of mathematics books written by the group.

QUESTION 18X lived during a time of political turmoil in France. X was a student at the École Normale, and was incensed when his school director decided to lock all students in during the Revolution. He wrote a blistering letter criticizing the director, which he submitted to the Gazette des Écoles, signing the letter with his full name. Although the Gazette's editor omitted the signature for publication, X was expelled.Ne pleure pas, Alfred ! J'ai besoin de tout mon courage pour mourir à vingt ans!The above were the last words of X. His works in mathematics are very important to this date, even though they only amount to 60 pages.ID X.

ANSWER

QUESTION 19*

X was introduced by John Wallis, and, since its introduction, has also been used outside mathematics in modern mysticism and literary symbology. Leopold Kronecker was skeptical of the notion of X and how his fellow mathematicians were using it in the 1870s and 1880s. This skepticism was developed in the philosophy of mathematics called ________, an extreme form of the philosophical and mathematical schools of constructivism and intuitionism. ID X.
