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.

    ECON: Confusing math regarding bonds?

    Here is a screenshot of a slide that the professor went over in class (PV = Present Value): http://dl.dropbox.com/u/64325990/ECON%20102/Capture.PNG I think the reason why I don't understand what's going on in the math is because I don't understand the question at all. So the bond pays $100...

    Σ and ∏ bonds and hybridization

    I am having difficulties understanding the concept of hybridization and the σ and ∏ bonds. My current understanding is that basically you just mix up a p and s orbital and it gives you an sp orbital, and if the bonds touch they are σ bonds, and if the bonds are parallel the are ∏ bonds. I don't...

    Why energy released when bonds formed

    Are coordination bonds always Lewis acid/base bonds?

    I read that coordination bonds can be formed when a Lewis base like NH3 uses its lone pair of electrons to bond to an empty d orbital on a transition metal. I don't get how this applies to elements with 5 or more electrons in their d orbital though. For example cobalt has 7 d electrons so I'm...
