<p>Quantum mechanics was developed in just two years, 1925 and
1926 (see <a href="https://plus.maths.org/content/why-quantum-mechanics">here</a> if you want to know why). There were initially two versions, one formulated by <a href="http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Heisenberg.html">Werner
Heisenberg</a> and one by <a href="http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Schrodinger.html">Erwin Schrödinger</a>. The two tuned out to be
equivalent.<p><a href="https://plus.maths.org/content/ridiculously-brief-introduction-quantum-mechanics" target="_blank">read more</a></p>https://plus.maths.org/content/ridiculously-brief-introduction-quantum-mechanics#commentsFP-belowquantum entanglementquantum mechanicsquantum physicsquantum superpositionquantum tunnelingSchrödinger equationThu, 19 May 2016 13:11:20 +0000mf3446567 at https://plus.maths.org/contentExplaining weirdness with weirdness

<p>A very strange way of explaining away the strangeness of quantum mechanics.</p>
</div>
</div>
</div>
<p>Quantum mechanics is famously strange. It says that tiny little
particles behave in a way we never, ever see bigger objects behave. The
theory can't be reconciled with the classical physics of Isaac Newton most
of us learn about at school. Yet, it performs so well that physicists
have no choice but to accept it.</p>

<p>In the <a href="https://plus.maths.org/content/schrodinger-1">previous article</a> we introduced Schrödinger's equation and its solution, the wave function, which contains all the information there is to know about a quantum system. Now it's time to see the equation in action, using a very simple physical system as an example. We'll also look at another weird phenomenon called quantum tunneling. </p> </div>

<p>Well, it goes to no-one because there isn't a Nobel Prize for maths. Some have speculated that Alfred Nobel neglected maths because his wife ran off with a mathematician, but the rumour seems to be unfounded. But whatever the reason for its non-appearance in the Nobel list, it's maths that makes the science-based Nobel subjects possible and it usually plays a fundamental role in the some of the laureates' work. Here we'll have a look at two of the prizes awarded this year, in physics and economics.</p>

<p>No-one won the Nobel Prize for mathematics in 2010 ... because there isn't a Nobel Prize for maths.
