Mathematical Models of Diatoms: Understanding Their Complex Shape, Reproduction and Chain Formation

Apart from physical and chemical solutions used by the diatom for survival, some features of the unicellular microalgae also could be described in mathematics. For instance, the diatom morphology reveals a striking alignment with the golden ratio and fractal geometry. By examining the silica shells of these unicellular algae, we…

Frustules: Design solutions in Diatoms

There are many microorganisms in the universe, and they can generally be sorted into three types: prokaryotic, eukaryotic, and acellular. The subject of this paper is a member of the eukaryotic family, and they are commonly present in nature: the diatom. The diatomite which is formed by the death of…

The Hydrodynamic Advantages of Shark Scales

This essay examines the drag-reductive properties of sharks’ scales and analyzes the macroscale and microscale structures and mechanisms that diminished turbulence for the fish in motion over the course of evolution. Fluid dynamics theory and Reynold’s number are used to explain the high reduction of turbulence and friction drag in…
