Lawrence Hargrave of Australia in 1891 pro duced what were probably the first
successful models of ornithopters. ... indicated that the two basic requirements for
flight, lift and thrust, could be treated separately with great resultant simplification
of the overall problem. ... It gave the results of his extensive observations of birds,
especially the larger soaring birds, which he had observed in northern Africa.

"Zoological Record is published annually in separate sections. The first of these is Comprehensive Zoology, followed by sections recording a year's literature relating to a Phylum or Class of the Animal Kingdom. The final section contains the new genera and subgenera indexed in the volume." Each section of a volume lists the sections of that volume.

Indexes the world's zoological and animal science literature, covering all research from biochemistry to veterinary medicine. The database provides a collection of references from over 4,500 international serial publications, plus books, meetings, reviews and other no- serial literature from over 100 countries. It is the oldest continuing database of animal biology, indexing literature published from 1864 to the present. Zoological Record has long been recognized as the "unofficial register" for taxonomy and systematics, but other topics in animal biology are also covered.

Offers an array of documents, short fiction, poems, songs, plays, movie scripts, and folklore to offer a look at the mass culture that was consumed by millions in Soviet Russia between 1917 and 1953. This work focuses on the entertainment genres that both shaped and reflected the social, political, and personal values of the regime and the masses.

Flight Physics

Just as Cayley, he discovered that flight does not entirely depend upon the
flapping of wings and that birds use this primarily for propulsion. ... Between 1891
and 1896 the Lilienthal brothers constructed a range of hang gliders on which
Otto would hang by his arms and ... Otto Lilienthal attempted to solve the problem
of powered flight by means of a carbon dioxide engine moving the wing tips up
and down. ... Otto Lilienthal was the first in history to perform controlled gliding
flights.

Knowledge is not merely everything we have come to know, but also ideas we have pondered long enough to know in which way they are related, and 1 how these ideas can be put to practical use. Modern aviation has been made possible as a result of much scienti c - search. However, the very rst useful results of this research became ava- able a considerable length of time after the aviation pioneers had made their rst ights. Apparently, researchers were not able to nd an adequate exp- nation for the occurrence of lift until the beginning of the 21st century. Also, for the fundamentals of stability and control, there was no theory available that the pioneers could rely on. Only after the rst motorized ights had been successfully made did researchers become more interested in the science of aviation, which from then on began to take shape. In modern day life, many millions of passengers are transported every year by air. People in the western societies take to the skies, on average, several times a year. Especially in areas surrounding busy airports, travel by plane has been on the rise since the end of the Second World War. Despite becoming familiar with the sight of a jumbo jet commencing its ight once or twice a day, many nd it astonishing that such a colossus with a mass of several hundred thousands of kilograms can actually lift off from the ground.
