In mathematics
Seven is the fourth prime number. It is not only a Mersenne prime (since 23 − 1 = 7) but also a double Mersenne prime since it is itself the exponent for another Mersenne prime (127). It is also a Newman-Shanks-Williams prime, a Woodall prime, a factorial prime, a lucky prime, a happy number and a safe prime.

Seven is the only number less than 15 which cannot be represented as the sum of the squares of three integers.

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[citation needed].





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...

A seven-sided shape is a heptagon. The regular n-gons for n ≤ 6 can be constructed by compass and straightedge alone, but the regular heptagon cannot. Figurate numbers representing heptagons (including seven) are called heptagonal numbers. Seven is also a centered hexagonal number.


There are seven frieze groups, the groups consisting of symmetries of the plane whose group of translations is isomorphic to the group of integers.

There are seven fundamental types of catastrophes.


When rolling two standard six-sided dice, it is the sum of any two opposite sides on a standard six-sided die. It has a 6 in 36 (or 1/6th) probability of being rolled (1–6, 6–1, 2–5, 5–2, 3–4, or 4–3), the greatest of any number.

did i lose you? I don't know what half of that stuff up there is talking about, but I do know this.

Today, June 23, 2009 is SEVEN years since Lance and I met. The first day of the rest of our lives.....
We couldn't have asked for a nicer day. We walked around the mall, sat and ' people watched', went eat at TGIF'S (can you believe they CLOSED it! the nerve of them!), went to Books a Million...then went to a park and walked, played on the swings, and sat on our temple a wooden structure they had in the middle of the park.
What was suppose to be lunch, turned into a 9 hour date!
What was suppose to be lunch, turned into 2 years later, on that very same date, June 23, on the very same temple wooden structure, being asked to marry him (and of course i said YES).
what was suppose to be lunch turned into 5 years and 2 more children later, and many happy memories (and some tough times too...but everyone has those!) and the rest of our lives still before us!!
even though he was 11 minutes late.... even though he says he kissed me first, and I KNOW i kissed HIM first....
We can't wait to celebrate our SEVENTH WEDDING ANNIVERSARY next!
I love you babe...thank you so much for the beautiful flowers you sent me. Thank you for being so thoughtful to even think about the day that started the rest of our lives!
I LOVE YOU!
There will be several post today...one, i couldn't resist, this one, and one more should post sometime today!
