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

Many people could probably use a haircut right now, after six months of a global pandemic, but probably not like Ewenice the sheep in Australia. She was recently found wandering with about 4-years of growth needing to be sheared off.The abandoned sheep was found in a heavily wooded area in southeast Australia, roaming on a property with no nearby flock or owner. A person spotted the sheep, burdened with the extra large fleece, and reported it to the Royal Society for the Prevention of Cruelty to Animals, or RSPCA.The RSPCA estimates the sheep, who they named Ewenice, had not been trimmed in about four years.Ewenice was checked over, given a haircut, and sent to a new home. About 44 pounds of wool was sheared off.“Carrying such a large fleece for an extended period of time would have had dire impact on this ewe’s welfare and quality of life. It was fantastic to see her transformation after shearing and to send her on to her new home,” said Head of Inspectorate Terry Ness.Fleece must be shorn regularly because sheep are unable to shed. 1057

Michelle Ferre, 24, has a passion for running, and has a passion for teaching. Because of the love she has for both the fourth-grade teacher at Crofton Elementary in Maryland gets to live out her dream. Running the Boston Marathon on Monday is the opportunity of a lifetime."To me I think of the Super Bowl for runners," she said. "It is just the biggest honor to ever be able to run in that race.""I am already nervous," she added. "I'm already thinking about it. For me it's just an opportunity to represent my school, represent my students and get to share it with them."Ferre is part of team Hyland's, which is one of the sponsors of the Boston Marathon. She's one of 13 teachers that were picked to be on the team from a pool of 1,600 applicants. Her students surprised her with the news at school. Part of the reason she was chosen is because of her alter ego."Pocketful of Primary is a brand name that I go by as a teacher online," said Ferre.Her YouTube channel, where she posts videos about teaching, has over 100,000 subscribers."For me it was a way to kind of create my own community of teachers to surround myself with and get inspiration from them and just really support each other when we need it," she said. And she's making a difference across the country."About a year ago I actually started a hashtag on Instagram '#pocketfulofpositivity' because I noticed among teachers sometimes there's a lot of negativity with everything we have going on," she said. "So, I wanted to be able to spread a positive message among teachers."Every time someone uses the hashtag, Ferre donates to 'DonorsChoose.org', a website that helps teachers get tools and resources for their classrooms. So far she has donated 0.Her dream of running the Boston Marathon will be realized on Monday then she'll go back to helping her fourth-graders in Crofton realize theirs one day at a time."I've got nothing but positive support from my kids," said Ferre. "The parents and my team teachers, my administrators, they've all been nothing but supportive." 2091

Los Angeles-area protests calling for justice for an 18-year-old man shot and killed by police last week ended Sunday when police reportedly fired tear gas and rubber bullets at protesters.Video from Sunday's demonstrations shows police using chemical dispersants and shooting projectiles at protesters in Compton.One protester told CNN that the confrontation escalated into violence when a demonstrator wouldn't "back down" to police.KCBS reports that six people were arrested for unlawful assembly, and one person was charged with resisting arrest.Demonstrators were calling for justice for 18-year-old Andres Guardado, who was shot and killed by Los Angeles County Sheriff's deputies in an alley behind a Los Angeles auto shop on Thursday.Police say Guardado flashed a gun and then fled as officers chased him. CNN reports that a deputy fired six rounds at Guardado. Investigators say they recovered an unregister semi-automatic pistol at the scene that included an illegal extended magazine loaded with live rounds.Guardado's family maintains that he was working as a security guard at the body shop at the time of the shooting, and added that they do not believe he owned a gun. But police officers claim that Guardado was not recognizable as a security guard because he did not have a uniform on and was not wearing a gun belt.California law also requires that security guards be at least 21 years old.Capt. Kent Wegener, the head of the department's Homicide Bureau, says investigators have taken six or seven exterior cameras from the scene of Thursday's shooting. It's unclear if any of the footage contains images of the shooting itself.Guardado's death marked the second fatal shooting by a Los Angeles County Sheriff's deputy in a week. 1756

MENTOR, Ohio — Some northeast Ohio salon owners are concerned House Bill 189, which proposes cuts in mandatory cosmetology training, could create a potential public safety issue.The measure sponsored by State Representatives Kristina Roegner (R-Hudson) and Alicia Reece (D-Cincinnati) calls for a reduction in training for cosmetology licensing from 1500 hours to 1000 hours.Bill proponents believe the measure will improve Ohio’s cosmetology laws by allowing more cosmetology graduates to enter the workforce earlier and with less debt, thus increasing entrepreneurship and bolstering the workforce for Ohio’s salons.But some local salon owners, like Jennifer Pealer with Jenniffer and Company Salon in Mentor, believe a reduction in required training can set-up future cosmetologists for potential salon mistakes. Pealer believes 1500 hours of training is needed to insure cosmetologists are prepared to use potentially hazardous chemicals and equipment on a daily basis."The biggest thing is public safety," said Pealer. "Hair damage can occur very easily without proper training. What happens is there is damage to the follicle, the hair breaks off, and if it's not reproduced, there could be balding."Salon owner Nancy Brown owns the Brown Aveda and Casal Aveda Institutes for cosmetology training in Northeast Ohio and believes HB-189, and its companion Senate bill, SB-129, are being considered for the benefit of chain salons, which provide quick hair cuts and not more technical services.Brown believes the measures sets cosmetologists up to be under-trained, and could also cut training for nail technicians to just 100 hours."The equipment we use requires training, the shears we use are sharp enough to perform surgery," said Brown. "Our curling irons at the professional level are 450 degrees. The pedicures and manicures, people have lost toes, they had all kinds of injuries because of uncleanness."News 5 reached out to State Representatives Kristina Roegner about bill benefits, but we're still waiting for a response.Those against HB-189 have set up an on-line petition.Meanwhile, Brown said the bill could be voted on in the House as early as mid-May. 2258
