### Happy Pi Day (March 14)

*UAS FH Construction Update for 3/14/2014*

**Happy Pi Day (March 14)**

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

π is a very important mathamatical constant and deserves a day of celebration.

Here is how some folks celebrate π Day

**Engineers: **

The Contractor has installed a seismic joint in the fire sprinkler system. To prevent waterlines from breaking during an earthquake, the Mechanical Engineer has called for the installation of seismic pipe joints placed at strategic locations in the building. These joints are designed to flex, bend and move during an earthquake. To celebrate π Day this Engineer has calculated the volume of water that will be required to fill this seismic pipe joint.

Volume = __π D ^{2} (L)__

4

V = (3.14159)(4=inch diameter pipe)^{2} (117 inches long)( / (4) = 1470 cubic inches

V = 1470 in^{3} / (231 in^{3}/gallon) = 6.4 gallons for each seismic pipe joint.

**Architects:**

Architects see the Greek letter “π” as an aesthetically pleasing symbol with calming curves and assortment of line widths. This makes it desirable to use in the design of buildings, sculptures and the design of appropriate apparel for Pi Day.

**Mathematician:**

π is an irrational number, - a number that it cannot be expressed as a simple fraction of a/b.

π is also a transcendental number, – a number that is not the root of any nonzero polynomial having rational coefficients.

The computation of π will continue infinitely without repetition or pattern. Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits. I have a friend who has memorized pi out to 12 digits. He will have to improve to 20 digits to make it on the www.pi-world-ranking-list.com for North America.

**English Teacher:**

Write a story in the π format 3.14159.

The story starts out with the first word containing 3 letters, then the second word has 1 letter, third word as 4 letters and on and on as long as you want to go. Pi has been calculated out further than you have paper for your story.

**Dessert Lovers**

We all love another reason to have a slice of Pie.

**Construction Update:**

The Contractor continues to make good progress inside the building framing interior walls, roughing in electrical and mechanical equipment. You will notice that we are getting a building of another different color this week as the contractor installs insulation on the exterior. Look for the first window to be installed today.
