1. half the acceleration and maximum speed, if the movements are also divided (if the pressure is equal)

2. I agree that pressure equals output. In other words, the movements have… homothetic parabolas.

Who doesn't know The Little Prince, the second most sought after book in the world – after the Bible – with more than 134 million copies sold worldwide since 1943? Its creator, Antoine de Saint-Exupéry (1900 – 1944), was a french writer brilliant, author of several successful books that are now part of French and international heritage.

Aviator by profession, first for the Post Office and then for the French Army during the Second World War, Saint-Exupéry's hours of flying inspired much of his work. They also stimulated his interest in technical and scientific subjects, a lesser-known aspect of his personality.

Thus, learning from his flying experience, he constantly sought to improve his planes and scribbled calculations and drawings in the margins of his manuscripts or on paper towels. Antoine de Saint-Exupéry criticized scientific rigor and praised the practical experience of men who risk their lives to go beyond the theories of engineers. Thus, from 1934 to 1941, he invented and patented 11 techniques in France and the United States; None of these patents made him any money, but some of his ideas were applied to American aircraft.

Autograph documents by Antoine de Saint-Exupéry, who died mysteriously at just 44 years old, have been in increasing demand and value for over fifty years, a result of the incredible worldwide success of the Little Princes. The self-portrait is particularly interesting here.
