Plenty of things in math are downright uninteresting. Who cares that the area of a circle is πr², or that a negative times a negative is a positive? Why should this interest us at all? Perhaps the answer can be found in the most unexpected results, the facts that have sometimes eluded even the best mathematicians. Here are some mind blowing math facts which will build up your interest in maths….
Anti-prime numbers (Opposite of Prime Numbers)
These are also called highly composite numbers (as coined by) and are divisible by a whole lot of other numbers. eg. 1, 2, 4, 6, 12, 24, 36.. A special number among these is 5040, which was also the best number considered by the famous Greek philosopher since, it is divisible by 60 different numbers! More at
Maths can be used to predict which words are funnier than others
A research at University of Alberta predicted that nonsense words with unpredictable letter combinations would be considered funnier than those with letters that occur most often in everyday speech. In math terms, lower entropy words (uncommon letter combinations) are considered funnier than higher entropy words (predictable letter combinations). For example, the nonsense word “finglam” is low entropy and would be considered funnier than the nonsense word “clester“, which is high entropy.
Highest Prime Number
As of January 2016 , the largest known prime number is 2^74207281 − 1, a number with 22,338,618 decimal digits. It was found in 2016 by the(GIMPS), which has also been finding world record primes since the year 1996! More at
The Birthday Paradox says that if there are 23 people in a room, there is a more than 50% chance that two people have the same birthday. It seems confusing because the probability of having a birthday on any particular day is only 1/365. But the difference relies on the fact that we only need two people to have the same birthday as each other.
In other words, if there are 23 people in a room, and you choose one person X, and ask, “Does anyone else have the same birthday as X,” the answer will probably be no. But then repeating this on the other 22 people increases the probability every time, resulting in a net probability of more than 50% (50.7% to be more precise).
Most difficult mathematical problem
No three positive integers a , b , and c satisfy the equation
a^n + b^n = c^n for any integer value of n > 2
This is. It was in the Guinness Book of World Records as the most difficult mathematical problem. It took about 350 years for any other mathematician to prove this. Below is what Fermat said exactly (translated).
It is impossible to separate a cube into two cubes, or a fourth power into two fourth powers, or in general, any power higher than the second, into two like powers. I have discovered a truly marvelous proof of this, which this margin is too narrow to contain.
Can you imagine losing $125 million thanks to a little metric system error?
That’s exactly what happened in 1999 when NASA lost a Mars orbiter because one team used metric units for a calculation and the other team didn’t.
Most sarcastic one! If you write out pi to two decimal places, backwards it spells “pie”.
