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

LOUISVILLE, Ky. — A third person who served on the grand jury that weighed charges against the police officers involved in the raid that led to the death of Breonna Taylor says she felt the investigation was incomplete.In an interview with The Associated Press, the woman said she thought prosecutors wanted only to give the officers involved "a slap on the wrist and close it up.""I felt like there should've been more charges," she told the AP in a phone interview.Taylor was killed on March 13 when officers conducted a narcotics raid on her apartment. Taylor's boyfriend, Kenneth Walker, said he drew a gun when he heard a pounding at the door. He maintains officers did not identify themselves and says he fired at officers when they breached the door, thinking they were intruders.Officers returned fire, killing Taylor. Kentucky Attorney General Daniel Cameron, who investigated the case, said officers were justified in returning fire because they were fired upon first.While officers say they did identify themselves as police and say a witness in the building also testified that they heard police ID themselves, several of Taylor's neighbors are on record as saying they did not know who was at the door.One officer, Brett Hankison, was charged with a crime in connection with the incident. He faces three counts of wanton endangerment for firing his gun toward the apartment building following the raid. No officers faced charges in connection with Taylor's homicide."All of (the officers) went in blindly, you really couldn't see into that lady's apartment as they explained to us, there was just a TV on," the grand juror told the AP of Taylor's apartment. She added that officers "went in there like the O.K. Corral, wanted dead or alive."The grand juror told The Associated Press that she was surprised that they were not presented with the opportunity to consider other charges. She also took issue with Cameron's justification in September that grand jurors had "decided" not to charge the other officers with a crime."I felt like he was trying to throw the blame on somebody else, that he felt like, we as jurors, we weren't going to (speak) out," she told the AP. "He made it feel like it was all our fault, and it wasn't."Typically, grand jury proceedings are held in secret and details of their investigations are held tightly under wraps. But following Cameron's press conference, a judge issued a ruling that allowed grand jurors to speak publicly about the process. Two grand jurors have since come forward to express their frustrations with how the case was handled."I didn't feel that the family was getting justice," the grand juror said. 2674

Millions of older Americans are growing old all alone. As Baby Boomers age, and start losing loved ones, loneliness can take its toll.The issue is becoming such a concern some national organizations are stepping in.“This was the one thing I said when I retire, I want to do Meals on Wheels,” says volunteer Donna Reuss.Reuss has been volunteering for the organization Meals on Wheels for six years. She not only brings seniors a free meal, but she’s often the only person they really interact with for weeks at a time.“One of the things that really surprised me when I first started this was how many seniors live alone,” Reuss says.Loneliness can have a big impact on their health. Research shows that lacking social connections can be as harmful to someone’s health as smoking 15 cigarettes a day.“It's a much bigger problem I think than people realize,” says Mary Lee Anderson, with Senior Services of Alexandria.Anderson’s nonprofit organization helps deliver food for Meals on Wheels. She’s helping with a new pilot project that lets volunteers delivering meals use a cell phone app to report any changes in behavior or concerns they notice while visiting with a senior.“It lets our volunteers, if they notice a problem, report it right on their phone,” she explains. “That information is sent back to us at the office and we can then contact the individual who is responsible, a family member or their city social worker if they don't have a close family member.”The pilot program is currently being tested in 10 cities across the country, and it’s expected to expand to another 50 cities early next year. 1619
