The word catenary is derived from the Latin word for "chain." In 1669, Jungius disproved Galileo's claim that the curve of a chain hanging under gravity ...

Huygens was the first to use the term catenary in a letter to Leibniz in 1690 and David Gregory wrote a treatise on the catenary in 1690. Jungius (1669) disproved Galileo's claim that the curve of a chain hanging under gravity would be a parabola.

Galileo's suggestion that a heavy rope would hang in the shape of a parabola was disproved by Jungius in 1669, but the true shape of the “chain-curve”, the catenary, was not found until 1690/91, when Huygens, Leibniz and John Bernoulli replied to a challenge by James Bernoulli.

Catenary Demonstration Experiment; Fun with hyperbolic cosine ... Changing the shape of the catenary. Notice the strings are longer here ('a' is larger). This was actually done first, then the strings quickly shortened for part II. ; The catenary is less sharp here for the longer strings to line up.

Correct! - Catenary ... The catenary equation is where a is determined by the linear density and tension of the chain. This is a transcendental curve rather than an algebraic curve like the parabola. The catenary is a hyperbolic function: .

A catenary is the curve formed by a flexible cable of uniform density hanging from two points under its own weigh. Cables of suspension bridges and attached to telephone poles hang in this shape. If the lowest point of the catenary is at , then the equation of the catenary is ;

Global warming scepticism and academic intolerance ... Someone very dear to me told me, a few weeks ago, that he had noticed I was becoming more and more intolerant with several positions and people —among them, climate change deniers. ... So I started thinking whether I was indeed failing to uphold the values of my profession;
