Oh yeah, since somebody does not believe what YOU believe; that makes us vapid...
I cannot grasp that what you call "Something happened to nothing, and that nothing became something, and it was smaller than than a period."
Seven, the fourth prime number, is not only a Mersenne prime (since 23 1 = 7) but also a double Mersenne prime since the exponent, 3, is itself a Mersenne prime. It is also a Newman-Shanks-Williams prime, a Woodall prime, a factorial prime, a lucky prime, a happy number (happy prime), a safe prime (the only Mersenne safe prime) and the fourth Heegner number.
Seven is the lowest number that cannot be represented as the sum of the squares of three integers. (See Lagrange's four-square theorem#Historical development.)
Seven is the aliquot sum of one number, the cubic number 8 and is the base of the 7-aliquot tree.
n = 7 is the first natural number for which the next statement does not hold: "Two nilpotent endomorphisms from Cn with the same minimal polynomial and the same rank are similar."
7 is the only dimension, besides the familiar 3, in which a vector cross product can be defined.
999,999 divided by 7 is exactly 142,857. Therefore, when a vulgar fraction with 7 in the denominator is converted to a decimal expansion, the result has the same six-digit repeating sequence after the decimal point, but the sequence can start with any of those six digits.[1] For example, 1/7 = 0.142 857 142.... and 2/7 = 0.285 714 285...
In fact, if one sorts the digits in the number 142857 in ascending order, 124578, it is possible to know from which of the digits the decimal part of the number is going to begin with. The remainder of dividing any number by 7 will give the position in the sequence 124578 that the decimal part of the resulting number will start. For example, 628/7= 89 + 5/7; here 5 is the remainder, and would correspond to number 7 in the ranking of the ascending sequence. So in this case, 628/7 = 89,714285... Another example, 5238/7 = 748 + 2/7, hence the remainder is 2, and this corresponds to number 2 in the sequence. In this case, 5238/7 = 748,285714...These might be one reason.
