<p>The 2012 Nobel Prize for Physics has been awarded to Serge Haroche and David J. Wineland for ground-breaking work in quantum optics. By probing the world at the smallest scales they've shed light on some of the biggest mysteries of physics and paved the way for quantum computers and super accurate clocks.</p>

<p>Quantum mechanics predicts the bizarrest things. Tiny particles
like electrons can simultaneously be in two
places, or, more generally, in two states that would seem mutually
exclusive in our everyday experience of physics. Similarly weirdly,
particles that have once interacted can remain <em>entangled</em> even
when they're moved far apart and then
influence each other instantaneously, something which Einstein called "spooky action
at a distance".<p><a href="http://plus.maths.org/content/nobel-prize-quantum-optics" target="_blank">read more</a></p>http://plus.maths.org/content/nobel-prize-quantum-optics#commentsNobel prizequantum computingquantum entanglementquantum mechanicsquantum physicsquantum superpositionTue, 09 Oct 2012 12:54:31 +0000mf3445788 at http://plus.maths.org/contentIn a spin

When it comes to the science of the very small, strange things start happening, and our intuition ceases to be a useful guide. <i>Plus</i> finds out about the crazy <b>quantum world</b>, and spin that a politician would die for. </div>

<h2>Heavens above</h2>
One of the great triumphs of nineteenth century physics was to enable us to go beyond the bounds of our ordinary experience. It was the culmination of Newton's realisation that the laws which govern what happens here on earth are the same as the laws that govern the way the planets move. Before Newton, people thought there were entirely different rules governing the heavens and the more mundane
region "down here".<p><a href="http://plus.maths.org/content/spin" target="_blank">read more</a></p>http://plus.maths.org/content/spin#comments22Dirac's equationelectron spinquantum computingquantum informationquantum mechanicsquantum superpositionFri, 01 Nov 2002 00:00:00 +0000plusadmin2215 at http://plus.maths.org/content
