What is Bonds: Definition and 202 Discussions

Barry Lamar Bonds (born July 24, 1964) is an American former professional baseball left fielder who played 22 seasons in Major League Baseball (MLB) with the Pittsburgh Pirates and San Francisco Giants. He received a record seven NL MVP awards, eight Gold Glove awards, a record 12 Silver Slugger awards, and 14 All-Star selections. He is considered to be one of the greatest baseball players of all time.Bonds holds many MLB hitting records, including most career home runs (762), most home runs in a single season (73, set in 2001) and most career walks. He led MLB in on-base plus slugging six times, and placed within the top five hitters in 12 of his 17 qualifying seasons.Bonds, an all-around baseball player, won eight Gold Glove awards for his defensive play in the outfield. He stole 514 bases, becoming the first and only MLB player to date with at least 500 home runs and 500 stolen bases (no other player has even 400 of each). He is ranked second in career Wins Above Replacement among all major league position players by both Fangraphs and Baseball-Reference.com, behind only Babe Ruth.However, Bonds led a controversial career, notably as a central figure in baseball's steroids scandal. In 2007, he was indicted on charges of perjury and obstruction of justice for allegedly lying to the grand jury during the federal government's investigation of BALCO. The perjury charges against Bonds were dropped and an initial obstruction of justice conviction was overturned in 2015.Bonds became eligible for the National Baseball Hall of Fame in 2013; he has not received the 75% of the vote needed to be elected, with his highest share of the vote coming in 2021 balloting, his 9th of 10 years of eligibility, when he received 61.8%. Some voters of the Baseball Writers' Association of America (BBWAA) have stated that they did not vote for Bonds because they believe he used performance-enhancing drugs.

    Can we break the hydrogen bonds in DNA with Phonon?

    Double stranded DNA are bind with hydrogen bonds in between the nitrogenous bases, Usually we use high temperature for denature,so can we break the hydrogen bonds with phonon because shorter wavelength give rise to heat, weather it is possible to denature the DNA?

    Hydrogen Bonds in Water and Ice

    Hi I've read sufficient literature on Ice/Water expansion to understand that when water freezes into a lattice, the hydrogen bonds between molecules are longer than they are in liquid water, hence ice expands. However, everything I've read seems to skip over the reason why with statements like...

    Understanding Covalent Bonds: Why Do They Hold Molecules Together?

    Why does a silicon atom in a silicon lattice have 4 single bonds?

    Silicon has 14 electrons, this means if it fills up its first two shells it will have 4 electrons in the outermost shell (These are the valence electrons). This shell can have 18 electrons in it, so silicon can have 14 more electrons in its outermost shell. This means it could...
