Mistakes can and does happen to everyone. Anyone who claims otherwise is either lying or does not do research.<br /><br />Just to cite a famous example, it took Poincare several papers to formulate the so called Poincare conjecture -- all of which (along with his other papers on algebraic topology) were erroneous.<br />See Dieudonne's beautiful exposition of Poincare's work in his "History of Algebraic and Differential Topology". Nevertheless, Poincare is accepted as the founder of the field of algebraic topology.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-69685398894857371792009-10-15T12:32:02.252-05:002009-10-15T12:32:02.252-05:00Wim, just think of them as 0-1 vectors.Wim, just think of them as 0-1 vectors.ryanwhttps://www.blogger.com/profile/09644595632189419277noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-88049426820318807352009-10-15T10:41:30.096-05:002009-10-15T10:41:30.096-05:00Is there a typo?
