Timeline Of Aviation – 18th Century
This is a list of aviation-related events during the 18th century (January 1, 1701 – December 31, 1800): 1700s–1770s *1709 **Portuguese Father Bartolomeu de Gusmão demonstrates a practical model of a hot-air balloon made of a paper envelope with burning material suspended below it to King John V of Portugal in the Ambassadors drawing room. Worried that it will set fire to the curtains, servants end its flight by dashing it to the ground. It is the first known demonstration of a practical lighter-than-air craft. *1716 ** Well thought-out glider-project of the Swedish scholar Emanuel Swedenborg. Basis for his construction are bird flight and the glider kite. *1738 **In his ''Hydrodynamica'' the Swiss scholar Daniel Bernoulli (1700–1782) formulates the principle of the conservation of energy for fluids (Bernoulli's principle), the relationship between pressure and velocity in a flow. *1746 **English military engineer Benjamin Robins (1707–1751) invented a whirling arm centr ...

Timeline Of Aviation
A timeline is a display of a list of events in Chronology, chronological order. It is typically a graphic design showing a long bar labelled with calendar date, dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time. This timescale is dependent on the events in the timeline. A timeline of evolution can be over millions of years, whereas a timeline for the day of the September 11 attacks can take place over minutes, and that of an explosion over milliseconds. While many timelines use a linear timescale—especially where very large or small timespans are relevant -- logarithmic timelines entail a Logarithmic number system, logarithmic scale of time; some "hurry up and wait" chronologies are depicted with zoom lens visual metaphor, metaphors.
