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

Millions of Americans are either at home trying to figure out how to pay their mounting bills, or out looking for work while worried about exposure to a deadly virus. The troubling state of society is proving beneficial to one particular group: scammers.“It makes sense that Americans are feeling that kind of economic and financial pressure, it is just really terrible that scammers are taking advantage of that,” said Lucy Baker.Baker is with the U.S. Public Interest Research Group, a watchdog organization based in Washington D.C that has been tracking COVID-19-related scams since May.In May, it found around 50,000 COVID-19 scams had been reported in the FTC’s database. When it went back to check the numbers last month, reported COVID-19 scams had jumped to over 200,000.“Kind of what was more shocking and right in your face was the number, 140 million,” said Baker. "That is the amount of money that had been lost due to these COVID-19 frauds.”Most of the scams are related to companies or individuals selling fake COVID-19 cures. Some are marketing PPE that is supposed to work better but does not.In one case, people were receiving flyers in the mail that instructed them to go to a URL that was supposed to be for coronavirus relief but instead it was a ploy for a used car business to get potential customers. The car dealership even sent fake checks with the flyers, stating it was money from the CARES Act for a new vehicle.According to U.S. PIRG, most people who’ve been scammed have lost around 0 on average. However, that number doubles to 0 for victims 80 years and older.So, organizations like PIRG, the DOJ and even AARP have put out top tips to avoid falling for a COVID-19 scam.“My biggest tip is to do your homework,” said Baker. "If you receive any kind of communication that seems off, smells fishy, it is too good to be true then it probably is.”Baker’s second tip is to be vigilant."The more you are aware that something like this could happen to you, the more likely you are to be able to stop it,” she explained.Lastly, most organizations recommend if you fall victim to a scam, report it. It is important to report it, regardless of how much money was lost or how embarrassed you may feel, because the more reported cases authorities get, the more information they have on the scams and scammers. Eventually, that will help officials find and stop the fraudulent activity. 2418

Medical offices around the country are opening back up for routine health checks and they're facing a huge problem; there's still a shortage of protective gear. Now, many are spending huge amounts of money restructuring the way they operate to keep themselves and their patients safe.On a window ledge at ENT and Allergy Associates in White Plains, New York, sits a number of brown paper bags. Inside, face masks labeled for each physician.“We have paper bags on our window sills with a bunch of masks. In there, we have 3-4-5 masks we’re rotating through. Those have to be kept covered to protect them from splatter or anything because once they get dirty, then they have to be thrown out,” Dr. Daniel Gold said. “We circulate gowns as well.”Gold is an E.N.T., which is the medical and surgical choice for anything having to do with the ears, nose or throat. It's a profession that is very much in your face, so protective gear is of utmost importance.“After wearing them for 5-10 minutes, you get short of breath and you’re like this is really hard,” he said.Doctors like Gold are having a hard time getting more gear. In fact, Dr. Gold often uses shields that are designed for sheet metal work because medical grade equipment is back ordered, or entirely unavailable. A surgical mask which once cost 30 or 40 cents now costs to .50.They've also found that knockoffs are being sold.“Not made of same material, not sealing against the face, and some had seam lines and then when you really looked, you’d realize there were holes through the seam lines that’s not blocking 95%,” Gold said. “You’re better wearing a t-shirt mask.”Dr. Gold is far from alone on this issue. It's a statewide and nationwide problem. Dr.Bonnie Litvack is the president of the Medical Society, State of New York.“That is an absolute mess because we can’t deliver the care if we don’t have the resources and the mask is ground zero for that,” Said Dr. Bonnie Livtack, the president of the Medical Society of the State of New York.When asked about whether they were able to negotiate for price on PPE, Litvack said, “With the various companies they either have it or they don’t, or you pay the prices or you don’t.”Dr. Litvack joined other state medical societies in the country by sending a letter to the Senate. They're asking the government to step in."We urge Congress to prioritize the production, distribution, and availability of PPE and testing, and accelerate efforts to conduct contact tracing,” the letter read. “All of these are essential to the safe reopening of medical practices and the economy and must be prioritized for all health care workers."They're also asking for financial help as their costs to operate, while seeing half the patient volume, are mounting.“These additional precautions and equipment is running us about per patient,” Dr. Gold said. “It’s about a million in extra overhead a month just in these extra masks, and gowns, and gloves and wipes. All these other things, which nobody could have thought to budget in because who would have thought we’d have to consider every patient highly infectious.”It's a new way of operating, as everyone is learning how to function in our new, post-pandemic world. 3229

MIDDLETOWN, Ohio — The things Lt. Col. Joe Jackson stored in his mother's basement before his most recent deployment couldn't be worth more than a few hundred dollars to a pawn shop, he said Tuesday night. They were family keepsakes, mostly: His father's Xavier class ring, relatives' dress watches and mementos from his other tours of duty. Nothing he felt he needed to worry about when he left for Afghanistan on Valentine's Day.They were gone when he returned for Thanksgiving, leaving him awash in "shock, anger and disappointment.""You realize the magnitude — the value beyond the monetary value of the things that were taken from you and how irreplaceable they are," he said. "Whether you can find them in a jewelry store or have them recreated, it's never going to be the same."His mother couldn't have moved them, he said. Multiple strokes have kept Rosalind Jackson in need of daily care since the turn of the century, and her family pays for a rotating team of caregivers to ensure her safety and comfort.She and her son believe one of those caregivers could be behind the theft. The culprit must have had both access to the home and in-depth knowledge of its contents, according to Joe Jackson. He didn't store his valuables in conspicuous containers."It makes me sick," his mother said. "Really."Jackson had returned to Fort Benning by Tuesday night. He said he had been working closely with Middletown, Ohio police to find leads and track down his missing possessions but encouraged members of the public to reach out with information as well.His hope? When he comes home again for Christmas, his treasured keepsakes will be there, too. 1682
