<p>question of whether it is possible to <a href="page.php?w=Hearing_the_shape_of_a_drum">hear the shape of a drum</a>. Weyl conjectured that the eigenfrequencies of a drum would be related to the area and perimeter of the drum by a particular equation, a result improved upon by later mathematicians.</p>

<p>The field of inverse problems was later touched on by <a href="page.php?w=Soviet_Union">Soviet</a>-<a href="page.php?w=Armenians">Armenian</a> physicist, <a href="page.php?w=Viktor_Ambartsumian">Viktor Ambartsumian</a>.</p>
