What is Balls: Definition and 555 Discussions

Edward Michael Balls (born 25 February 1967) is a British broadcaster, writer, economist, professor and former politician who served as Shadow Chancellor of the Exchequer from 2011 to 2015. A member of the Labour Party and Co-operative Party, he was Member of Parliament (MP) for Morley and Outwood, formerly Normanton, from 2005 to 2015.
Balls attended Nottingham High School before studying philosophy, politics and economics at Keble College, Oxford, and was later a Kennedy Scholar in economics at the John F. Kennedy School of Government, Harvard University. He was a teaching fellow at Harvard from 1988 to 1990, when he joined the Financial Times as the lead economic writer. Balls had joined the Labour Party whilst attending Nottingham High School, and became an adviser to Shadow Chancellor Gordon Brown in 1994, continuing in this role after Labour won the 1997 general election, and eventually becoming the Chief Economic Advisor to the Treasury.
At the 2005 general election, Balls was elected as the MP for Normanton (which in 2010 became Morley and Outwood), and in 2006 became Economic Secretary to the Treasury. When Brown became Prime Minister in 2007, Balls became Secretary of State for Children, Schools and Families, serving until the 2010 general election; Labour were at that point defeated after thirteen years in government, and returned to Opposition. He was appointed as Shadow Secretary of State for Education under Harriet Harman and finished in third place at the 2010 Labour leadership election, triggered by Gordon Brown's resignation as Leader of the Labour Party, after which he was appointed as Ed Miliband's Shadow Home Secretary. He served in this role until 2011, when he was then appointed as Shadow Chancellor of the Exchequer, a role that he held until he was unseated at the 2015 general election.
Following his electoral defeat, he became a senior fellow at Harvard University Kennedy School's Mossavar-Rahmani Center for Business and Government, and a visiting professor to the Policy Institute at King's College London. He was appointed chairman of Norwich City F.C. in December 2015, a position he held until December 2018. In 2020 he was appointed Professor of Political Economy at King's College London. Balls was a contestant on series 14 of the BBC's Strictly Come Dancing, surviving until week 10, and in 2021 was the winner in BBC's Celebrity Best Home Cook.

    The Heisenberg Uncertainty of Bowling Balls

    I was recently thinking about the Heisenberg Uncertainty Principle which states that we can not know a subatomic particle's position and momentum at any instant. We can know one or the other measure but not both at the same time. The more we know about one, the less we know about the other...

    Why Does a Ball Spin When Thrown?

    When you throw a ball, why does it spin? Does it have to do with the air resistance? Obviously, you can spin it when you throw it, but it seems to spin even if you just "push" it up. Is it that I'm just not being precise here? Is this related at all to why it's easier to balance on a bike...
