HAPPY PI DAY!!!

Standard

Ok I have to get my geek on. Today is the official day for that pesky little number that we have to use to determine the diameter of a circle 3.14!! Here are a few little tidbits of history about PI

  • The ancient Babylonians generally calculated the area of a circle by taking 3 times the square of its radius (pi=3), but one Old Babylonian tablet (from ca. 1900-1680 BCE) indicates a value of 3.125 for pi.
  • Ancient Egyptians calculated the area of a circle by the following formula (where d is the diameter of the circle): formula:  [(8d)/9] squaredThis yields an approximate value of 3.1605 for pi.
  • The first theoretical calculation of a value of pi was that of Archimedes of Syracuse (287-212 BCE), one of the most brilliant mathematicians of the ancient world. Archimedes worked out that 223/71 < pi < 22/7. Archimedes’s results rested upon approximating the area of a circle based on the area of a regular polygon inscribed within the circle and the area of a regular polygon within which the circle was circumscribed.
  • A novel way to compute pi:  An eighteenth-century French mathematician named Georges Buffon devised a way to calculate pi based on probability. Buffon’s method begins with a uniform grid of parallel lines, a unit distance apart. If you drop a needle of length k < 1 on the grid, the probability that the needle falls across a line is 2k/pi. Various people have tried to calculate pi by throwing needles. Depending on when you stop the experiment, you can obtain a reasonably accurate estimate of pi.
  • The symbol for PI was introduced by the British mathematician William Jones in 1706, who wrote:

    3.14159 =pi

    This symbol was adopted by Euler in 1737 and became the standard symbol for pi.

Orange Beach and Mobile, AL

Standard

About a month ago, hubby told me we had a little extra and we could plan for a quick trip to the coast (it’s a 6 hr drive so not a major undertaking) and spend a couple of days. So for the last month we planned everything to make sure we could swing it and we decide to go for it. Last week we spent a couple days down in Orange Beach. It was a really nice quick trip. We got to go see the USS Alabama in Mobile and all the tanks and airplanes they had on display. After that we went over to Orange beach and spent 1 day and 2 nights in Orange Beach directly on the water 🙂  We got see jelly fish, a little sand crab, and a blue heron as well. It was great to have that quick trip for a refresh
