Varia Rejecta Mathematica: online journal publishing papers that have been rejected from peer-reviewed journals in the mathematical sciences. Isaac Newton referring to Robert Hooke in a letter of 20 June 1686 to Edmund Halley: Now is not this very fine? Mathematicians that find out, settle & do all the business must content themselves with being nothing but dry calculators & drudgers & another that does nothing but pretend & grasp at all things must carry away all the invention as well of those that were to follow him as of those that went before (The Correspondence of Isaac Newton, Volume II, 1676-1687. Edited by H.W. Turnbill, F.R.S. Cambridge, Published for the Royal Society at the University Press, 1960, p. 438). D. Fanelli (2009). How many scientists fabricate and falsify research? A systematic review and meta-analysis of survey data. PLoS ONE 4(5): e5738. doi:10.1371/journal.pone.0005738 Joe Doob: I cannot give a mathematically satisfactory definition of non- mathematical probability. For that matter I cannot give a mathematically satisfactory definition of a nonmathematical chair. The very idea of treating real life as mathematics seems inappropriate to me. But a guiding principle in my work has been the idea that every nonmathematical probabilistic assertion suggests a mathematical counterpart which sharpens the formulation of the nonmathematical assertion and may also have independent mathematical interest (J.L. Snell. A conversation with Joe Doob. Statist. Sci., 12:301-311, 1997. See p. 305).
