The <em>Strong Fields, Integrability and Strings</em>
programme, which took place at the Isaac
Newton Institute in 2007, explored an area that
would have been close to Isaac Newton's heart:
how to unify Einstein's theory of gravity, a
continuation of Newton's own work on
gravitation, with quantum field theory, which
describes the atomic and sub-atomic world, but
cannot account for the force of gravity. </div>

<p>It's been nearly 18 months since the Large
Hadron Collider at CERN started up and scientists are eagerly awaiting their first glimpse into the
cosmic mysteries it was designed to explore. But when can we realistically
expect the first ground-breaking discoveries to come through? Last week, <a href="http://ph-dep-th.web.cern.ch/ph-dep-th/?site=php/viewprofile.php&id=31">John Ellis</a>,
outgoing leader of the theory division at CERN, addressed an audience
of physicists at the University of Cambridge to update them on the
current state of play. <em>Plus</em> went along and also managed to
catch Ellis for a quick interview.</p>

<p>This week CERN <a href="http://press.web.cern.ch/press/PressReleases/Releases2011/PR01.11E.html">announced</a> that the Large
Hadron Collider (LHC) will run until the end of 2012, rather than being shut down earlier for an upgrade, as had been planned.
"If LHC continues to improve in 2011 as it did in 2010, we've got a very exciting year ahead of us," said CERN's Director for Accelerators and Technology, Steve Myers. "The signs are that we should be able to increase the data collection rate by at least a factor of three over the course of this year."</p><p><a href="http://plus.maths.org/content/whats-happening-lhc" target="_blank">read more</a></p>http://plus.maths.org/content/whats-happening-lhc#commentsmathematical realityblack holedark matterhiggs bosonHiggs fieldholographic principleLHCstring theoryWed, 02 Feb 2011 14:50:39 +0000mf3445415 at http://plus.maths.org/contentThe illusory Universe

With online socialising and alternative realities like <i>Second Life</i> it may seem as if reality has become a whole lot bigger over the last few years. In one branch of theoretical physics, though, things seem to be going the other way. String theorists have been developing the idea that the space and time we inhabit, including ourselves, might be nothing more than an illusion, a hologram
conjured up by a reality which lacks a crucial feature of the world as we perceive it: the third dimension. <i>Plus</i> talks to <b>Juan Maldacena</b> to find out more. </div>

<p><i>With many of us living a good chunk of our lives online it may seem as if reality has become a whole lot bigger over the last few years. In one branch of theoretical physics, though, things seem to be going the other way. Over the last two decades string theorists have been developing the idea that the space and time we inhabit, including ourselves, might be nothing more than an
illusion, a hologram conjured up by a reality which lacks a crucial feature of the world as we perceive it: the third dimension.<p><a href="http://plus.maths.org/content/illusory-universe" target="_blank">read more</a></p>http://plus.maths.org/content/illusory-universe#comments5151ablack holecosmologyentropygeneral relativityholographic principlequantum gravityquantum mechanicsrelativitystring theoryTue, 30 Jun 2009 23:00:00 +0000plusadmin2364 at http://plus.maths.org/content
