  1. Writing out all terms for a \(2\times 2\) matrix \(A\), explicitly verify that \[ \epsilon_{ij} \epsilon_{mn} A_{im} A_{jn} = 2\det A. \] where the indices \(i,j,m,n\) take values 1 and 2.
  2. For a three by three matrix A show that \[ \det A = \epsilon_{ijk} A_{i1}A_{j2} A_{k3}.\]

GellMann theorizes about doing research

Node id: 3072pdf_document

GellMann, who shaped particle physics from sixties to nineties, including proposal of QCD, passed away recently.
Read what lessons Gell-Mann gives about doing research. In two words,"WHY NOT".
In particular it is interesting to see how he gives examples to show that in research, "doubt and messiness are inevitable."
He also recalls a conversation with Dirac when he asked him why Dirac did not predict positrons right away?
Read Dirac's surprising response and more .....
