<p><big>History of diffusion in physics</big></p>
<p>In the scope of time, diffusion in solids was used long before the theory of diffusion was created. For example, <a href="page.php?w=Pliny_the_Elder">Pliny the Elder</a> had previously described the <a href="page.php?w=cementation_process">cementation process</a>, which produces steel from the element <a href="page.php?w=iron">iron</a></p><p>
