This is why the Euler spiral can be used to describe all types of rat whiskers, even though they come in many different shapes. Some are s-shaped, some get more curly towards the tip, and some get ...

Given how rat whiskers follow the Euler spiral, and that spirals are so common in nature, we think there’s a good chance the whiskers of other mammals probably follow similar rules and may also be ...

The whiskers all have different lengths and shapes, and their distribution is such that each whisker is represented as an interval on the Euler spiral. The researchers conjecture that this ...

An Euler spiral. In particular, because the Euler curve has a transition from flat to curved, it has been used for designing the parts of railway tracks or roads that make this transition.
