Math enthusiasts know all about it, and the rest of the population is probably hoping for cherry pie.But March 14 is Pi Day. While last year stretched the symbolic celebration out a little longer -- to 3.1415 -- each year presents ample opportunity for learning.To 31 decimal places, the celebrated irrational number that never ends is 3.1415926535897932384626433832795.A few more tidbits about pi and Pi Day:About piPi is the ratio of the circumference of a circle to its diameter. It's not equal to the ratio of any two whole numbers, so an approximation -- 22/7 -- is used in many calculations.Pi is essential in architecture and construction and was used frequently by early astronomers. Pi has been known for about 4,000 years, but it started to be called by the Greek letter only in the 1700s.The origin of Pi DayPi Day started 30 years ago at San Francisco's Exploratorium.Physicist Larry Shaw, who worked in the electronics group at the museum, started celebrating pi on March 14, 1988, primarily with museum staffers. The tradition has grown to embrace math enthusiasts from all walks of life.For more about pi, visit www.piday.org. 1159

MARTIN COUNTY, Florida — As early as next week, you could start to see an improvement in the water quality in Martin County.Officials plan to start cleaning up some of the areas most impacted by algae. They hope to give residents some relief from the sight and smell of the algae and help the estuary recover from its damaging effects.Martin County Ecosystem Division Manager John Maehl said because the county declared a local state of emergency earlier this week, it can more quickly obtain grant funds from the Department of Environmental Protection to pay for and expedite clean up efforts.The plan is to get contracted clean up crews on the water early next week, possibly by Tuesday. Even before declaring the state of emergency, county officials had been interviewing and researching companies with technology they say can clean up the algae, without creating more harm to the environment.By next week, Maehl said at least a couple are prepared to get to work.In at least one case, they would be vacuuming the algae from the water.Exactly where the clean up will happen is unclear, but Maehl said the county has been surveying the area, looking to create a priority list of the places they will send crews to first.That could be areas such as Central Marine, typically hit hard by the thickest of the algae.“The really nasty stuff, try to get that out and take away the most noxious component of this and then let the estuary do its thing. The estuary is remarkably resilient,” Maehl said.This is the first year the county has taken on algae clean up effort, so it is a learning experience.“It’s a really complicated issue with a lot of different solutions and really the approach we’re taking is we’re throwing a lot of stuff against the wall and see what sticks,” Maehl said.Stuart resident Teresa Cooper is among those glad to see action being taken.She lives right along the water and can smell the stench of the algae while walking her dog.“I don’t walk him over there, so I just kind of keep him on the side, because it’s bothering me, I’m sure it’s bothering him,” Cooper said. “It hurts your throat and just smells very bad."Maehl said the county also hopes, by next week, to place booms in strategic areas to hold and collect algae. That could include putting a boom in canals leading to the St. Lucie Estuary to keep algae from flowing into the waterway.Maehl is not sure if the cleanup will last for weeks or months. 2457
