|
||
<p>One of the most interesting and perhaps surprising features of many
|
||
body physics is the existence of distinct phases of matter.</p>
|
||
<p>Why does liquid turn to ice? Well there are two key ingredients.
|
||
First we need a system composed of a large number of objects and second
|
||
we need those objects to interact with eachother.</p>
|
||
<p>It turns out that the more objects there are, the greater the effect
|
||
that their interactions has on the whole. A hundred <span
|
||
class="math inline">\(H_2O\)</span> molecules can’t actually form the
|
||
nice regular structure that characterises ice, instead you’d get more of
|
||
a blob. However, any human scale amount of water contains an
|
||
unimaginable huge number of molecules.</p>
|
||
<p>Phases come about when the interactions between individuals
|
||
components serve the reinforce</p>
|
||
<p>When a many body, interacting system can display radically different
|
||
properties depending on the system parameters</p>
