By David Derbyshire for MailOnline. Lucky: Seven is seen as the world's favourite number - and it appears across many cultures and religions. Stop any person in the street and ask them to choose an odd number between 1 and More often not, they will say the number 7. There are seven days of the week, seven colours of the rainbow, seven notes on a musical scale, seven seas and seven continents. Snow White ran off to live with seven dwarves, there were seven brides for seven brothers, Shakespeare described the seven ages of man, Sinbad the Sailor had seven voyages.

Only had the right ring. This week, a poll of 30, people confirmed that 7 is overwhelmingly our favourite number β with 3 in second place. A remarkable ten per cent of those surveyed gave 7 β from the infinite choice of numbers available β as their lucky number. What is so special about 7? Our fascination with certain numbers goes back to the dawn of recorded history.

For the Ancient Babylonians the most meaningful number was They based their mathematics and calendar around it β and we, many centuries later, have inherited their system. In Ancient Egypt, 12 was considered special. In Egyptian mythology there were 12 realms of the dead.

Indeed, 12 crops up throughout history β inches to a foot, pennies to a shilling, months of the year, the number of apostles. A day is split into two cycles of 12 hours. There are sensible reasons to venerate 60 and Both divide neatly into halves, quarter and thirds, making them ideal units of currency and measurement.

Mathematician Alex Bellos, who carried out the survey as part of research for his book on maths, Alex Through The Looking Glass, says an emotional attachment to numbers β and 7 in particularly β is surprisingly common. Favourite numbers are usually linked to birthdays, anniversaries or house numbers. But some people have the strangest reasons. Bellos argues that some numbers are inherently more appealing than others.

Small numbers tend to be more popular than large ones, for example. We are most familiar with the numbers 1 to 10, and tend to pick our favourites from those. Most people see odd numbers as more exotic than even ones.

Can numbers be funny? Author Joseph Heller spent some time deciding that 22 was funnier than 11 or We also seem to be attracted to prime numbers. So when looking for a favourite number, that makes 3, 5 and 7 the most likely candidates. We are so used to rounding up numbers to the nearest multiple of 10 that numbers finishing in 5 seem oddly unsatisfactory.

That knocks 5 out the running, and three β the second favourite β misses out on first place, possibly because it is just too mundane. After all, we see groups of 3 everywhere we look: traffic lights with 3 colours, sets of knives, forks and spoons, 3 hands on a clock, 3 meals a day.Globe Icon An icon of the world globe.

This sieve is similar to the Sieve of Eratosthenes that generates the primesbut it eliminates numbers based on their position in the remaining set, instead of their value or position in the initial set of natural numbers.

The term was introduced in in a paper by Gardiner, Lazarus, Metropolis and Ulam. They suggest also calling its defining sieve, "the sieve of Josephus Flavius" [1] because of its similarity with the counting-out game in the Josephus problem.

Lucky numbers share some properties with primes, such as asymptotic behaviour according to the prime number theorem ; also, a version of Goldbach's conjecture has been extended to them. There are infinitely many lucky numbers. Because of these apparent connections with the prime numbers, some mathematicians have suggested that these properties may be found in a larger class of sets of numbers generated by sieves of a certain unknown form, although there is little theoretical basis for this conjecture.

Twin lucky numbers and twin primes also appear to occur with similar frequency. Continue removing the n th remaining numbers, where n is the next number in the list after the last surviving number. Next in this example is 9.

One way that the application of the procedure differs from that of the Sieve of Eratosthenes is that for n being the number being multiplied on a specific pass, the first number eliminated on the pass is the n -th remaining number that has not yet been eliminated, as opposed to the number 2n. That is to say, the list of numbers this sieve counts through is different on each pass for example 1, 3, 7, 9, 13, 15, When this procedure has been carried out completely, the remaining integers are the lucky numbers:.

The lucky number which removes n from the list of lucky numbers is: 0 if n is a lucky number. It is not known whether there are infinitely many lucky primes. From Wikipedia, the free encyclopedia.

If you show someone a collection of objects randomly scattered around on a tabletop or on a computer screenβ¦.

DEVLIN: β¦seven is the largest number of objects where they will recognize that there were seven objects. Beyond that, you have the need to count them or group them either physically or mentally. But up to seven, you can recognize them immediately. And the other interesting thing about seven is that if you ask people to pick a number between one and 10, almost everybody picks the number seven.

I don't think that tells you anything about the mathematics of seven. It tells you a little bit about how the human mind deals with things like randomness and arbitrary representations. If you start forming all of the obvious fractions - one-seventh, two-sevenths, three-sevenths, all the way up to six-sevenths - something very interesting happens. If you work out one-of-a-seven, you get a decimal, 0. Okay, so far so good.

Work out two 7s, you get 0. And that's a curiosity, I thinkβ¦. DEVLIN: I have no idea, whatsoever, except that, you know, if we forget lucky numbers, there is a mathematical notion called a happy number. To get a happy number, you look at the number and you start squaring the digits and adding the answers.
