What is the oldest document known relating to the existence of Pi?
- A.
The Suse tablette from the Babylonians
- B.
The Rhind papyrus from the Egyptians
- C.
Paper on the method of Archimedes
- D.
A carved stone
Correct Answer
A. The Suse tablette from the BabyloniansExplanation
The Suse tablette from the Babylonians is considered the oldest document known relating to the existence of Pi. This tablet, dating back to around 1900-1600 BCE, contains a mathematical table that approximates the value of Pi to four decimal places. It is significant because it demonstrates that the Babylonians had an understanding of the concept of Pi and were able to calculate its value accurately. This tablet provides valuable insight into the mathematical knowledge and achievements of the ancient Babylonian civilization.Rate this question:

How are the first few digits of Pi written in binary?
- A.
11.1110111101111100
- B.
1.10111011010010011
- C.

- D.
11.0010010000111111
Correct Answer
D. 11.0010010000111111Explanation
The given answer, 11.0010010000111111, represents the first few digits of Pi written in binary. In binary, each digit can be either 0 or 1, and the digits to the left of the decimal point represent the whole number part of Pi in binary, while the digits to the right of the decimal point represent the fractional part. Therefore, the given answer accurately represents the binary representation of the first few digits of Pi.Rate this question:

The definitions of Pi through geometry because of the Euclidian geometry and integral calculation from below. Mathematicians now go for analytical definitions a lot more abstract. Notably, the famous paper of Bourbaki Pi is defined as:
- A.
The constant such that exp(i*π)=-1
- B.
The double of the unique root to the equation cos(x)=0 between 0 and 2
- C.
The real number that appears in the differention 2*π*e(x) of the function e(x), unique continu homorphism of the additive group R on the multiplicative group U of the complex number of absolute number 1
- D.
The perimeter of an apple π divided by it's diameter
Correct Answer
C. The real number that appears in the differention 2*π*e(x) of the function e(x), unique continu homorpHism of the additive group R on the multiplicative group U of the complex number of absolute number 1Explanation
The correct answer is the real number that appears in the differentiation 2πe(x) of the function e(x), unique continuous homomorphism of the additive group R on the multiplicative group U of the complex number of absolute number 1. This definition refers to the mathematical concept of Pi as a constant that arises in the differentiation of the exponential function. It highlights the relationship between Pi, the imaginary unit i, and the exponential function e(x).Rate this question:

Another important concept, the universal number. We don't know if Pi is one. What practical consequence could this have if the hypothesis were checked?
- A.
We could find the Bible and our own biography at a precise place in the decimals of π translate in letters
- B.
We could calculate the size of the universe
- C.
We could finally have a discussion with π
- D.
We won't need to calculate it's decimal anymore because we could guess them using the previous one
Correct Answer
A. We could find the Bible and our own biograpHy at a precise place in the decimals of π translate in lettersExplanation
If the hypothesis were true and we could find the Bible and our own biography at a precise place in the decimals of π, translated into letters, it would imply that π is a normal number. A normal number is one in which every possible sequence of digits occurs with equal frequency. This would have significant implications, as it would suggest that π contains all possible combinations of letters, making it a rich source of information. It would open up possibilities for encoding and decoding messages, and potentially revolutionize communication and information storage.Rate this question:

A contemporary mathematician and who participated in the research of Pi owned a number plate whose number was P 314159. Nowadays it's in hexadecimal, who was it?
- A.
Simon Plouffe
- B.
David Bailey
- C.
Peter Borwein
- D.
David Chudnovsky
Correct Answer
B. David BaileyExplanation
The correct answer is David Bailey. David Bailey is a contemporary mathematician who participated in the research of Pi. The number plate mentioned, P 314159, is a reference to the first six digits of the mathematical constant Pi (3.14159). Therefore, it is likely that the number plate belongs to David Bailey.Rate this question:
