Cam newton panthers super bowl12/18/2023 ![]() ![]() In the years since, Newton has become one of the league's stars, leveraging his size, arm and legs to become one of the most dynamic players in football. The quarterback quickly acclimated to the new competition, throwing 21 touchdowns and passing for more than 4,000 yards to earn Offensive Rookie of the Year honors. The Carolina Panthers, the NFL’s worst team in 2010, selected Newton with the first pick. 1 pick in the 2011 draft, but many football experts wondered openly if Newton would be worth the investment. The tumult surrounding Newton’s college career certainly raised questions about his ability to make it in the National Football League. Auburn officials denied any money had exchanged hands, and in October 2011, following a 13-month investigation, the NCAA announced it had found no evidence that Auburn had paid Newton to play for the school. However, controversy continued to shadow Newton, as allegations surfaced that the quarterback’s father had sought and received payment from schools for his son’s athletic services. He also won the Heisman Trophy in a landslide victory. He led the school to the 2010 BCS National Championship and along the way was named both the Southeastern Conference Player of the Year and the AP Player of the Year. Over the course of his single season at the community college, Newton resurrected his reputation as one of the most dynamic amateur quarterbacks in the nation, paving the way for his return to Division I football at Auburn University.Īt Auburn, Newton was a dominating force. His landing ground was Blinn College in Brenham, Texas. In January 2009, three days before the Gators won the national championship, Newton announced he was transferring. However, the incident scarred his reputation and he was suspended by the team. Newton, who has always claimed he was unaware the computer was stolen when he purchased it from another student, managed to avoid serious charges after he completed a pretrial intervention program for first-time offenders. ![]() Controversy and Move to AuburnĮverything changed on November 21, 2008, when Newton was arrested and charged with felony counts of burglary, larceny and obstruction of justice following the alleged theft of a laptop from another Florida student. The expectation was that Newton would eventually get his time at Florida. The following year, Newton sat out almost the entire season as a medical redshirt after suffering an ankle injury. These contests were largely geared toward players who didn’t play quarterback, but Newton, already a 6'5", 230-pound athlete, frequently jumped into the fray.Īs a freshman, Newton played in just a handful of games and largely watched from the sidelines as the team’s starting QB, Tim Tebow, steered a Heisman Trophy-winning season. The team's success was fueled by hard, testosterone-driven practices that featured players squaring off one-on-one to wrestle each other to the ground. Under the hand of head coach Urban Meyer, the Florida Gators boasted one of college football’s elite programs. Many believed Newton had made the right choice. Newton chose to attend the University of Florida at the start of his senior year of high school. Gator Football at the University of Florida By his senior year, Newton, one of the top high school prospects in the country, had received scholarship offers from the University of Georgia, the University of Florida and Virginia Tech, among other college football powerhouses. Big and fast, the quarterback packed a cannon of an arm and the kind of foot speed reserved for receivers. Football, part-time jobs and household chores kept his sons busy.Īt Westlake High School in Atlanta, Newton quickly earned the attention of college football scouts from around the country. While Newton’s mother, Jackie, stayed on top of her boys’ studies, their father, Cecil, cast a large shadow over their sports lives and weekend activities. The second of three boys, Newton hailed from a home in which athletics and hard work were a central part of growing up. Early Career in FootballĬameron Jerrell Newton was born on May 11, 1989, in Atlanta, Georgia. In June 2020, he signed with the New England Patriots. At the end of his 2015 MVP season, he led the Panthers to an appearance in Super Bowl 50. Selected by the Carolina Panthers with the first pick in the 2011 NFL draft, Newton became one of the league's stars. ![]() He initially attended the University of Florida and later led Auburn University to the national title in his Heisman Award-winning season of 2010.

Harry winston eternity band12/18/2023 ![]() ![]() ![]() He regularly showed off his collection in touring exhibitions, such as the 1949 “Court of Jewels,” which featured the Hope diamond. Winston was renowned for his eye for the finest of gemstones and the ability to design pieces in order to best flaunt their natural dazzle. ![]() Winston was also a pioneer of marketing as the first jeweler to dress an Academy Awards nominee when he loaned some diamond jewelry to Jennifer Jones for the 1944 Oscar ceremony. The rarity and beauty of the gemstones he pursued and presented in his boutiques made the Winston brand synonymous with excellence. Many others followed, including the 726.60-carat Vargas from Brazil which, in 1938, he tracked down across multiple continents after he read a brief newspaper notice about its discovery. The first of the celebrated diamonds to be purchased by Winston was the 726-carat uncut Jonker, acquired in 1935. in 1932, where he influenced 20th-century-jewelry trends by always elevating the stones rather than adding the lavish decorations that had pervaded jewelry in the 19th century. His early success involved turning that eye to estate sale collections that he transformed by freeing gemstones from dated ornamentation, giving them new cuts and modern settings. Winston’s father had immigrated to New York from Ukraine and ran a small jewelry shop where a young Harry learned about precious stones, enough, the story goes, to identify a real emerald in a heap of pawnshop jewelry at the age of 12. Today, Winston is regarded as the “King of Diamonds” and the “Jeweler to the Stars” as one of the first to recognize the branding power of lending glitzy earrings, necklaces and other fine jewelry for red-carpet events. 7-day return policy for a full cash refundĪmong the famed gemstones that Harry Winston (1896–1978) encountered over the course of his career was the Hope diamond, which he donated to the Smithsonian Institution in 1958.

It has 26 lines and 14 of them are variations of “pah,” “rum,” or “pum.” This reminds me of an old saying I just made up, “Give a child a drum on Christmas morning, you’ll be drinking by Christmas noon.” Instead, listen to: “The Friendly Beasts,” by Sufjan Stevens, a traditional carol about the gifts the animals gave Baby Jesus, not a girl who wants a dang hippo.Ħ) The Little Drummer Boy: There are so many versions of this and the only one mildly tolerable is the one where David Bowie pops ’round Bing Crosby’s place for a Christmas song. It’s a jaunty ’50s pop song but dear li’l Gayla’s voice is oddly grown-up for a kid so it all seems a bit disturbing. Instead, listen to: “Christmas Card From A Hooker In Minneapolis,” by Tom Waits, is your better haven’t-seen-you-in-a-long-time holiday classic.ħ) “I Want A Hippopotamus For Christmas” by Gayla Peevey: Another kid-sung novelty number, this one from 1953 by 10-year-old Gayla Peevey who - did you guess it? - wants a hippopotamus for Christmas. Instead of wishing each other a Merry Christmas and going on their way, they decide to go for a drink, find all the bars closed - because people are home with their families! - and buy a six-pack, which they polish off in the car and then drive home. She’s married he’s a successful musician. Hankey, the Christmas Poo,” from the TV series “South Park,” because if you’re going to listen to a bad song from an animated show, don’t mess around.Ĩ) “Same Old Lang Syne” by Dan Fogelberg: The singer runs into his old high school flame at the supermarket on Christmas Eve, which makes this probably the only holiday song with a protagonist stalking someone in the frozen food section. That said, I do still have the “Chipmunk Punk” album my parents gave me for Christmas 1980, and you have not lived until you’ve heard their version of “My Sharona.” But most of them who like this song liked it when they were 7 and grew out of it. Instead, listen to: “Joel the Lump of Coal,” by the Killers, which tells the story of Joel, a lump with feelings, and his journey to a naughty little boy.ĩ) “The Chipmunk Song (Christmas Don’t Be Late)” by Alvin and the Chipmunks: Sure, a lot of people do like Alvin and the Chipmunks. Gordon has had a long and accomplished career - president of the Screen Actors Guild, the role of rabbi on Larry David’s “Curb Your Enthusiasm” - so clearly he’s got somethin’ going for him. He sings about all the bad things he did and the snitches who ratted him out and by the time its two-and-a-half minutes is over you’re fully in favor of the kid getting nothing. ![]() Instead, listen to: “Underneath the Mistletoe” by Sia is a better choice for a kissing-under-a-parasitic-plant holiday love song.ġ0) “Nuttin’ For Christmas,” Barry Gordon: There’s a subset of bad Christmas songs that feature annoying kids singing insipid songs - you’ll find another one further down the list - and this 1955 ditty by a then-6-year-old Gordon was both a Top 10 hit and an eternally grating tune. Instead, listen to: “Christmas (Baby Please Come Home” by Darlene Love, a truly great longing-for-love holiday song. Plenty of fine, racy holiday songs exist, but not many that endorse adding a mistress to your missus. ![]() It starts off wrong and gets worse from there. “Baby,” though, is kid’s stuff compared to this 1990 track from the Aussie hard rockers. So let’s open the little doors on our Worst Holiday Songs advent calendar and see what’s inside, starting with …ġ2) “Mistress For Christmas,” AC/DC: Some people don’t like “Baby, It’s Cold Outside” for its out-of-date sentiments about male-female relations. And after conducting a highly unscientific study using YouTube and a focus group of friends, the results are in: These are the worst.īut because it’s the holidays, we also suggest some much better alternatives to listen to instead. This is a chronicle of the bad holiday songs that we - by which I mean, me - despise the most. This is not a story about good songs like those. Nat King Cole singing “The Christmas Song,” Bing Crosby’s hit with “I’ll Be Home For Christmas (If Only In My Dreams).” Or maybe something a bit peppier such as Brenda Lee’s “Rockin’ Around The Christmas Tree,” or Mariah Carey and “All I Want For Christmas Is You.” There are wonderful holiday songs, of course. Holiday music is the best … except when it’s the worst. ![]() Tiling shapes geometry12/18/2023 ![]() ![]() ![]() So after Smith told Kaplan about the hat tile, Kaplan turned to a program he’d written that simply places copies of a tile around an initial seed tile in ever-growing rings. It’s impossible to create an algorithm that can determine, for every possible collection of tiles, whether they tile the plane (let alone whether they are aperiodic). “The real art is finding a shape that will allow you to tile the whole plane, but won’t let you do it in a periodic way,” Socolar said. You can, for instance, use a couple of vertical dominoes while otherwise filling the plane with horizontal dominoes. It’s easy to make tilings that aren’t periodic from tiles that also form periodic tilings. Perhaps hobbyists, unlike mathematicians, are “not burdened with knowing how hard this is,” Senechal said. And then there was Joan Taylor’s discovery of the Socolar-Taylor tile. Marjorie Rice, a California housewife, found a new family of pentagonal tilings in 1975. Robert Ammann, who worked as a mail sorter, discovered one set of Penrose’s tiles independently in the 1970s. “I’m not used to this kind of thing.”īut this is far from the first time a hobbyist has made a serious breakthrough in tiling geometry. The excitement the tiles have generated has felt “a bit surreal,” said Smith, who lives in the coastal town of Bridlington in northern England. In the days since the announcement, mathematicians and tiling hobbyists have rushed to get their hands on the new tiles, making paper cutouts, 3D-printing them, and making hat quilts and cookies. The hat tile, Senechal said, shows that periodic and aperiodic tiles are more closely linked than mathematicians had realized. ![]() With just a little work, anyone with a magic marker and a hexagonally tiled bathroom floor can trace out a hat tiling. This divides every hexagon into six “kites.” Each hat is made of eight adjacent kites, combined from neighboring hexagons. To get a hat tiling from a hexagonal tiling, first connect the midpoints of the opposite sides of the hexagons. What its tilings do have is a deep relationship with a particular periodic tiling: the honeycomb lattice of hexagons. The hat, by contrast, has no symmetry and is “almost mundane in its simplicity,” the authors wrote. What’s more, they realized, the hat is one of infinitely many different tiles of this type. The hat tile embodies “enough complexity to forcibly disrupt periodic order at all scales,” the researchers wrote in their paper. Mathematicians call such a tile, or set of tiles, “aperiodic,” in contrast to shapes like squares or hexagons that can cover the plane in a repeating (or periodic) fashion. On March 20, Smith and Kaplan, together with two more researchers, announced that the hat tile was something mathematicians have been seeking for more than five decades: a single tile whose copies can fill the entire plane, but only in patterns that don’t consist of a repeating block of tiles. “It’s a tricky little tile.” He sent a description of his tile to Craig Kaplan, an acquaintance and computer scientist at the University of Waterloo in Canada, who immediately started investigating its properties. “I noticed that it was producing a tessellation that I had not seen before,” he said. Smith cut out 30 copies of the hat on cardstock and assembled them on a table. Usually when he created tiles, they would either settle into some repeating pattern or fail to tile much of the screen. Now he was experimenting to see how much of the screen he could fill with copies of that tile, without overlaps or gaps. Using a software package called the PolyForm Puzzle Solver, he had constructed a humble-looking hat-shaped tile. In mid-November of last year, David Smith, a retired print technician and an aficionado of jigsaw puzzles, fractals and road maps, was doing one of his favorite things: playing with shapes. ![]() AuthorWrite something about yourself.
