In geometry, the Weaire–Phelan structure is a complex 3-dimensional structure representing an idealised foam of equal-sized bubbles, with two different shapes. In 1993, Denis Weaire and Robert Phelan found that this structure was a better solution of the Kelvin problem of tiling space by equal volume cells of minimum surface area than the previous best-known solution, the Kelvin structure.

The St. Louis Cardinals are an American professional baseball team based in St. Louis. The Cardinals compete in Major League Baseball (MLB) as a member club of the National League (NL) Central division. Since the 2006 season, the Cardinals have played their home games at Busch Stadium in downtown Saint Louis. One of the nation's oldest and most successful professional baseball clubs, the Cardinals have won 11 World Series championships, more than any NL team and second in MLB only to the New York Yankees. The team has won 19 National League pennants, third-most of any team. St. Louis has also won 14 division titles in the East and Central divisions. In 1881, entrepreneur Chris von der Ahe purchased the Brown Stockings barnstorming club, renamed it the St. Louis Browns, and made it a charter member of the American Association baseball league. The team won four league championships, qualifying them to play in the era's professional baseball championship tournament, a forerunner of the modern World Series. In two of these championships, the Browns met the Chicago White Stockings, launching the enduring Cardinals–Cubs rivalry. In 1892, the Browns – also called the Perfectos – joined the National League. In 1900, the team was renamed the Cardinals. (Two years later, an unrelated St. Louis Browns team joined the American League.) Notable Cardinals achievements include manager/owner Branch Rickey's invention of the farm system, Rogers Hornsby's two batting Triple Crowns, Dizzy Dean's 30-win season in 1934, Stan Musial's 17 MLB and 29 NL records, Bob Gibson's 1.12 earned run average (ERA) in 1968, Whitey Herzog's Whiteyball, Mark McGwire's single-season home run record in 1998, and the 2011 championship team's unprecedented comebacks. The Cardinals have won 105 or more games in four seasons and won 100 or more nine times. Cardinals players have won 20 league MVPs, four batting Triple Crowns, and three Cy Young Awards. Baseball Hall of Fame inductees include Lou Brock, Dizzy Dean, Bob Gibson, Whitey Herzog, Rogers Hornsby, Joe Medwick, Stan Musial, Branch Rickey, Red Schoendienst, Ozzie Smith, and Bruce Sutter. In 2018, Forbes valued the Cardinals at $1.9 billion, 7th-highest among MLB clubs and far more than the $147 million paid in 1995 by owner William DeWitt, Jr.'s investment group. In 2017, the team took in revenue of $319 million on an operating income of $40.0 million. John Mozeliak is the President of Baseball Operations, Mike Girsch is the general manager and Mike Shildt is the manager. The Cardinals are renowned for their strong fan support: despite being in one of the sport's mid-level markets, they routinely see attendances among the league's highest, and are consistently among the top three in MLB in local television ratings. Through 2020, the Cardinals' all-time win-loss record is 10,948–10,091 (.520)
