About two weeks to go before collisions and data-taking start again.<\/li>\n<li>Physics Today has a <a href=\"http:\/\/physicstoday.scitation.org\/doi\/10.1063\/PT.3.3551\">report this month on the LHeC proposal<\/a>, something that has not gotten as much attention as it deserves.  This is a proposal to collide protons and electrons, by building a new electron machine and a detector at a collision point with the LHC beam.  Unlike proposals for a 100 TeV proton-proton machine that are getting a lot of attention, this would not push the energy frontier, but it would cost a great deal less (estimate is half a billion to a billion, vs. multiple tens of billions for the 100 TeV machine).  In a few years when the question of a follow-on machine to the LHC starts to get very pressing, this idea and the HE-LHC idea (higher field magnets in the LHC tunnel, maybe doubling the energy) may get a lot more attention as the only financially viable ways forward.<\/li>\n<li>The Universit&eacute; de Montpellier today has started to make accessible about 18,000 pages of its <a href=\"https:\/\/grothendieck.umontpellier.fr\/\">archive of Grothendieck&#8217;s mathematical writings<\/a>.
