The understanding of natural forms and their classications attracted natural scientists and mathematicians since antiquity. The presentation asks whether there can be a well-dened mathematical point of view, a clear system of classication that is useful for science and can say something new. The classication we propose is based on the static equilibrium points that are comprehensible also as the singularities of the gradient of the distance from the centre of gravity. The number of equilibria and the topology of the integral curves connecting them (the so-called Morse{Smale complex) create our proposed classication the completeness of which is a mathematical question of equal interest to search for suitable natural phenomena that can be described by this classication. The presentation discusses the main mathematical issues and the geological, biological, palaeontological and astrophysical applications.
