The way most recursive functions are written, they seem to be circular at first glance, defining the solution of a problem in terms of the problem itself ("A rose is a rose is a rose").

In 1903, Aegidius Elling of Norway designed and built an 11-hp gas turbine that used steam injection between the combustion chamber and the turbine to cool the combustion gases to a safe temperature for the materials available at the time.
