The mystery of PRIMES

“We like to think of ourselves as the basic numbers.2 3 5 7 …..We can describe any whole number uniquely just break down the number any whole number to its prime factorizationNo two numbers have the same set of primesWe’re infinite in number , yet Only one of us is even- 2 is the only even prime.The rest of us are oddThe only factors of any prime are 1 and itselfNo one can take us apartNo one can factor us furtherWe’re not composite.We’re Prime! We’re Prime!”

What is the ‘mystery’?
![Page 11: Fascinating Aspect of Math](https://reader033.vdocuments.site/reader033/viewer/2022042623/546341e0af795939028b664d/html5/thumbnails/11.jpg)
Prime numbers become rarer as we progress through the integers.
And the block of 1,000 numbers just below and
including 10 million has only 53 primes.

Sense of beauty lies not in complexity but in Simplicity of representation and proof.

‘Prime Numbers are fascinating : they seem to be randomly distributed along
the number line, yet are capable of producing beautiful patterns.’

‘Every Prime Number is an Even Multiple of Three, Plus or Minus One’ or (to say the same thing slightly differently)
‘Every Prime Number (except 2 and 3) is a Multiple of Six, Plus or Minus One.’
5 = 3 × 2 – 1 7 = 3 × 2 + 111 = 3 × 4 – 113 = 3 × 4 + 117 = 3 × 6 – 119 = 3 × 6 + 123 = 3 × 8 – 129 = 3 × 10 – 131 = 3 × 10 + 137 = 3 × 12 + 141 = 3 × 14 – 1

This leads me to yet another mystery about prime numbers mathematicians have always
wondered is given any moment of time , what is the biggest prime that we know about?

Primes in Nature
![Page 35: Fascinating Aspect of Math](https://reader033.vdocuments.site/reader033/viewer/2022042623/546341e0af795939028b664d/html5/thumbnails/35.jpg)
In Nashville, every 13 years, the forests get drowned out for six weeks by the chorus of an insect- cicadas
This cicadas survival depends on exploiting the strange properties of some of the most fundamental numbers in mathematics - the primes
The cicadas appear periodically but only emerge after a prime number of years.
![Page 36: Fascinating Aspect of Math](https://reader033.vdocuments.site/reader033/viewer/2022042623/546341e0af795939028b664d/html5/thumbnails/36.jpg)
Because 13 and 17 are both indivisible this gives the cicadas an evolutionary advantage as primes are helpful in avoiding other animals with periodic behaviour. Suppose for example that a predator appears every six years in the forest. Then a cicada with an eight or nine-year life cycle will coincide with the predator much more often than a cicada with a seven-year prime life cycle.
![Page 37: Fascinating Aspect of Math](https://reader033.vdocuments.site/reader033/viewer/2022042623/546341e0af795939028b664d/html5/thumbnails/37.jpg)
These insects are tapping into the code of mathematics for their survival. The cicadas unwittingly discovered the primes using evolutionary tactics

It is almost impossible to spot a pattern that will help you to predict where the next prime will be found.We know primes go on for ever but finding a pattern in the primes is one of the biggest mysteries in mathematics.
