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

Max Booth is from Redondo Beach and was excited to go to Maine for a summer camp for the second year. This year, that didn’t happen because of coronavirus, leaving Max at home. Then, his grandparents stepped in to save the day.Tim and Joy Booth live in Pacific Beach and said right around when Max found out he would be staying home for the summer, beaches and public places in their area started opening up, so they took advantage and planned a substitute summer camp for the 10-year-old.“It gave us real happiness to figure out how to make something that was at least a little bit similar to what he might have had,” said Joy.The trio spent the last week exploring the San Diego area, completing a long list of activities like cutting wood and barbecuing at a park, going to the beach, playing at a water park, practicing archery, hiking and observing nature, completing a junior park ranger program at the Cabrillo Monument and more. They even took the time to give back to the community, spending a day shoveling sand off of steps in Pacific Beach. They said a police officer and surfer stopped to thank them, the surfer adding that he had slipped on those steps because of the built-up sand.“We swept the stairs because we wanted to help people not get any injuries from slipping on the sand,” said Max.The week may have been different than a typical summer camp, but all three said they had the best time."I would just like to say thank you for being my parents and thank you for doing all this stuff for me," said Max."You’re welcome, Max. We love you," responded Tim and Joy. 1591

MEXICO CITY (AP) — Mexican authorities said a group of about 350 migrants broke the locks on a gate at the Guatemalan border Friday and forced their way into southern Mexico to join a larger group of migrants trying to make their way toward the United States.The National Immigration Institute did not identify the nationalities of the migrants, but they are usually from Central America.A similar confrontation occurred on the same border bridge between Mexico and Guatemala last year.RELATED: Where federal government falls short, San Diego agencies fill in to help migrantsThe institute said the migrants were acting in a "hostile" and "aggressive" way, and accused them of also attacking local police in Metapa, a Mexican village that lies between the border and the nearby city of Tapachula.The group of 350 pushed past police guarding the bridge and joined a larger group of about 2,000 migrants who are walking toward Tapachula in the latest caravan to enter Mexico.Claudia Jaqueline Sandoval, 43, from El Progreso, Honduras, was walking toward Tapachula with her 6-year-old daughter. Another son and a daughter are already in the United States.RELATED: Judge blocks Trump's asylum policy but delays enforcement"I have been HIV positive for 16 years," said Sandoval, but her reason for going north was not just medical treatment. "It has been two years since I heard from my son" in the United States, and money is scarce, she said.There are already several groups of migrants in the southern border state of Chiapas who have expressed frustration at Mexico's policy of slowing or stopping the process of handing out humanitarian and exit visas at the border.A group of several hundred Cuban, African and Central American migrants have been waiting at the immigration offices in Tapachula for documents that would allow them to travel to the U.S. border, where most plan to request asylum.RELATED: Mexico is apprehending more migrants. Is it because of Trump?Some members of that group have scuffled with immigration authorities and broken windows at the offices in recent days, accusing officials of making them wait too long for papers.And another group of an estimated 2,500 Central American and Cuban migrants have been stuck for at least a week further west in the Chiapas town of Mapastepec, also waiting for papers. 2337

Luxury fashion house Prada is withdrawing products after some items displayed in a Manhattan storefront were seen as depicting blackface imagery.The products, part of Prada's Pradamalia line, were pulled Friday after images surfaced of some merchandise depicting monkey-like figures with black faces and large red lips.New York-based civil rights attorney Chinyere Ezie spotted the products at the Prada store in Manhattan's Soho shopping district by happenstance on Thursday after recently returning from a conference in Washington.While in the nation's capital, she visited the Smithsonian National Museum of African American History and Culture. She wrote on Facebook?that she was struck by how the items looked similar to images she saw in an exhibit on blackface at the museum and that seeing the products left her "shaking with anger."As of Friday afternoon, Ezie's Facebook post had been shared more than 9,000 times.Prada said?in a statement Friday that the Pradamalia products depict "imaginary creatures not intended to have any reference to the real world and certainly not blackface.""Prada Group never had the intention of offending anyone and we abhor all forms of racism and racist imagery. In this interest we will withdraw the characters in question from display and circulation," the statement read.Ezie said she felt Prada's response constituted the "same paltry excuses that we've heard throughout history about racist imagery," telling CNN affiliate WABC that Prada is "a multinational, multibillion dollar company. They can do their own research about what these painful images mean. There was no mistaking it, there was no ambiguity."The Pradamalia line of products was debuted by Prada last month and are described as "a new family of mysterious tiny creatures that are one part biological, one part technological, all parts Prada," according to their website. The figure was one of seven characters developed by the fashion house.Pradamalia imagery can be found on branded keychains, cell phone cases, clothing, jewelry, and various leather goods that range in price from 0 to 0.Another Italian luxury house also faced controversy recently for offensive videos and private Instagram messages, allegedly sent by Dolce and Gabbana co-founder Stefano Gabbana.The videos featured an Asian model struggling to eat Italian food with chopsticks, stereotypical Chinese music, and mispronunciation of the brand's name, with some interpreting this as mocking the way Chinese people say "Dolce & Gabbana." Screen captures of the Instagram messages appear to show a series of direct messages in which Gabbana complains about criticisms of the videos. The fallout led to the cancellation of a major fashion show in China. 2781

MEXICO CITY — Volunteer searchers found 12 skeletons and one decomposed body in a shallow pit in the desert near the Mexican resort of Puerto Penasco.Prosecutors in the northern border state of Sonora said late Thursday that two of the bodies may be women. Tests are being conducted to determine the gender and identity of the bodies.Prosecutors said only one of the bodies was relatively recent; the others were "complete skeletons with clothing."The bodies were found by a group of women who are volunteer searchers. The group is made up of relatives of missing people who investigate reports of clandestine burial sites.Because of deficient police investigations, such volunteer groups have been responsible for discovering mass graves and burial pits in many parts of Mexico.Drug and kidnapping gangs use such pits to dispose of the bodies of victims or rivals.Puerto Penasco is also known as Rocky Point. It is located on the Gulf of California, also known as the Sea of Cortez.While not as violent as some other parts of Mexico, Puerto Penasco has been known for Sinaloa drug cartel activity and a large-scale shootout between cartel gunmen and military forces occurred there in 2013. 1198
