THE AIRPLANE the plane was an invention with greater impact for mankind, because it all started with the idea that people could fly.
Timeline: - Around 400 BC in Greece, Archytas was reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have flown some 200 m (660 ft) - the 9th-century poet Abbas Ibn Firnas and the 11th-century monk Eilmer of Malmesbury; both experiments injured their pilots. - In 1502 Leonardo da Vinci researched the wing design of birds and designed a man-powered aircraft in his Codex on the Flight of Birds - In 1799, Sir George Cayley set forth the concept of the modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. - Cayley was building and flying models of fixed-wing aircraft as early as 1803 - Cayley built a successful passenger-carrying glider in 1853 - In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach. - In 1883, the American John J. Montgomery made a controlled flight in a glider. - Sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot (34-meter) wingspan that was powered by two 360-horsepower (270-kW) steam engines driving two propellers. In 1894, his machine was tested with overhead rails to prevent it from rising. The test showed that it had enough lift to take off. The craft was uncontrollable, which Maxim, it is presumed, realized, because he subsequently abandoned work on it. - In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. His box kite designs were widely adopted. - Between 1867 and 1896 the German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights. - The Wright brothers flights in 1903 are recognized by the Fédération Aéronautique Internationale (FAI), the standard setting and record-keeping body for aeronautics, as "the first sustained and controlled heavier-than-air powered flight". - In 1905, the Wright Flyer III was capable of fully controllable, stable flight for substantial periods. The Wright brothers credited Otto Lilienthal as a major inspiration for their decision to pursue manned flight. - In 1906, Alberto Santos Dumont made what was claimed to be the first airplane flight unassisted by catapult and set the first world record recognized by the Aéro-Club de France by flying 220 meters in less than 22 seconds. - An early aircraft design that brought together the modern monoplane tractor configuration was the Bleriot VIII design of 1908 - A. Vlaicu nr. 1, was finished in 1909, and was test flown on June 17, 1910. From the first flight the airplane had no need of changes. - In 1015, World War I served as a testbed for the use of the airplane as a weapon. - Alcock and Brown crossed the Atlantic non-stop for the first time in 1919. - The first international commercial flights took place between the United States and Canada in 1919 - Airplanes had a presence in all the major battles of World War II. - The first 'operational' jet aircraft was the German Heinkel He 178, which was tested in 1939. - In 1943, the Messerschmitt Me 262, the first 'operational' jet fighter aircraft, went into service in the German Luftwaffe. - In October 1947, the Bell X-1 was the first aircraft to exceed the speed of sound. - The first jet airliner, the de Havilland Comet, was introduced in 1952 - The Boeing 707, the first widely successful commercial jet, was in commercial service for more than 50 years, from 1958 to 2010. - The Boeing 747 was the world's biggest passenger aircraft from 1970 until it was surpassed by the Airbus A380 in 2005.

We chose the phone because it was an actor in the communications and is one of the most modern and developed devices now adays. A important fact of cellphones is that it allow people to communicate easyer with others and reduce distance between people in a certain way, it also, in this days, has important applications to develop activities in study, job and whatever.
This is the time line:
In 1972 the first cellphone was created, it wheight 800grams and was called Duna from Motorola.
In1982 Nokia launched its first mobile called “ Mobira senador”. Its wheight: 9.8kg
In 1997 the first cellphone whit photographyc camera made by Philippe Kahn was released.
Samsung’s sph-mido was the first pone whit maps , it was launche in 1999
2001,Sony Ericson TG8 was the first cellphone with bluetooth
in 2005, the Nokia N91 was the first cellphone with wifi
Finally, in 2008, Apple made the first Smartphone: the iphone.
Evolution of the Camera; The camera is older tha the photography in the 10 th century was a dark room with a hole to see the eclipses, then in the 16 th and 17 th century that was used as a dark camera where the artist, who is in one end, draw his objective, in 1830 it was discovered and called photosensitive photographic camera. The photographic evolution was created by George Eastman in 1889 with the first kodak portable camera and theur movies, In 1936 appeared the reflex camera that revolutionazed the cameras, then the polaroid that is recognized around the world as instant photography by Edwin Land, then the digital camera appeared and the diferencce is that it can save the photographics with an electronical device,
