The inventors of the first airplane were Orville and Wilbur Wright. On December 17, 1903, the Wright brothers made the first successful experiment in which a machine (aka airplane) carrying a man rose by its own power, flew naturally and at even speed, and descended without damage.
"Flight is possible to man...[and] I feel that it will soon cost me an increased amount of money if not my life". - Wilbur Wright Co-Inventor of the first engined airplane. -The invention of airplane changed the way we travel and also made traveling very comfortable. Airplanes gave us the opportunity to explore different parts of the world. Tackling emergency situations like floods became easier. Airplanes are also an important part of the defense services. The aircraft that we see today can be classified into two types i.e. fixedwing aircraft and rotatory-wind aircraft. Earlier, in the 18th century, hot air balloons were developed for flight. It was in 1783 that the Montgolfier Brothers built a hot air balloon for the first time. The lack of thrust needed to power the aircraft and absence of navigation tools were the major problems associated with hot air balloons. However, this didn't stop people from working in the field of airplane development and eventually the airplane was invented.

Wilbur and Orville, the Wright Brothers were born on 16th April, 1867 and 19th August, 1871 respectively. They didn't continue their education after high school and instead decided to open a bicycle repair shop. They used to study the experiments and research taking place in the field of airplane development. Their interest and passion for airplanes led to the development of the first heavier-than-air plane.

Pinhole Camera Alhazen (Ibn Al-Haytham), a great authority on optics in the Middle Ages who lived around 1000AD, invented the first pinhole camera, (also called the Camera Obscura} and was able to explain why the images were upside down. The first casual reference to the optic laws that made pinhole cameras possible, was observed and noted by Aristotle around 330 BC, who questioned why the sun could make a circular image when it shined through a square hole.
Some say the first 'camera' was designed before Christ. It was by simple deduction that an artist noticed a faint image on the opposing wall of a small building where a small hole let in light from outside of the building. He worked on a lens that could be placed in a similar hole of another building and he noticed that the image on the opposite wall was rather clear, color and all, although upside down. He then proceeded to use oil paints that were in use to paint portraits at the time. He simply mixed the oils to match the colors and painted directly onto the image he was looking at. (Today's cameras do the same thing minus the oil paint. Film cameras have replaced the oils with both silver halide salts and dyes. Digital cameras simply use super miniature diodes, photo-etched onto silicon chips, to translate different ranges of the color spectrum into digital code.)
Inventor Charles E. Alden claimed, in the 29 April 1906 issue of the New York World, to have invented a device called the “vest pocket telephone" although Alden never had the chance to produce this device in large quantities. [9][10][11] The first mobile telephone calls were made from cars in 1946. Bell System's Mobile Telephone Service was made on 17 June in St. Louis, Missouri, followed by Illinois Bell Telephone Company's car radiotelephone service in Chicago on 2 October. [12] The MTA phones were composed of vacuum tubes and relays, and weighed over 80 pounds (36 kg).[13][14] There were initially only 3 channels for all the users in the metropolitan area, increasing later to 32 channels across 3 bands. This service continued into the 1980s in large portions of North America. Due to the small number of radio frequencies available, the service quickly reached capacity. In 1956, the world’s first partly automatic car phonesystem, Mobile System A (MTA), was introduced in Sweden. John F. Mitchell, Motorola's chief of portable communication products in 1973, played a key role in advancing the development of handheld mobile telephone equipment. Mitchellsuccessfully pushed Motorola to develop wireless communication products that would be small enough to use anywhere and participated in the design of the cellular phone.[15][16]Martin Cooper, a Motorola researcher and executive, was the key researcher on Mitchell'steam that developed the first hand-held mobile telephone for use on a cellular network.[17]Using a somewhat heavy portable handset, Cooper made the first call on a handheld mobile phone on 3 April 1973 to his rival, Dr. Joel S. Engel of Bell Labs.[18][19] As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones or cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life. —Martin Cooper, [20] The new invention sold for $3,995 and weighed two pounds, leading to a nickname "the brick". The world's first commercial automated cellular network was launched in Japan by NTT in 1979, initially in the metropolitan area of Tokyo. In 1981, this was followed by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway and Sweden.[21] Several countries then followed in the early-to-mid 1980s including the UK, Mexico and Canada. On 6 March 1983, the DynaTAc mobile phone launched on the first US 1G network by Ameritech. It cost $100m to develop, and took over a decade to hit the market.[22] The phone had a talk time of just half an hour and took ten hours to charge. Consumer demand was strong despite the battery life, weight, and low talk time, and waiting lists were in the thousands. [23][24] In 1991, the second generation (2G) cellular technology was launched in Finland by Radiolinja on the GSM standard, which sparked competition in the sector as the new operators challenged the incumbent 1G network operators. Ten years later, in 2001, the third generation (3G) was launched in Japan by NTT DoCoMo on the WCDMA standard.[25] This was followed by 3.5G, 3G+ or turbo 3G enhancements based on the high-speed packet access (HSPA) family, allowing UMTS networks to have higher data transfer speeds and capacity. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications like streaming media.[26] Consequently, the industry began looking to data-optimized 4th-generation technologies, with the promise of speed improvements up to 10-fold over existing 3G technologies. The first two commercially available technologies billed as 4G were theWiMAX standard (offered in the U.S. by Sprint) and the LTE standard, first offered in Scandinavia by TeliaSonera.
We use mobile phone everyday. I own a blackberry and a Nokia phone. In the 90s the cellphone was a luxury item. I thought it would be an interesting idea to dig out a little history about mobile phone.
Dr. Martin Cooper of Motorola, made the first US analogue mobile phone call
1.
Dr. Martin Cooper of Motorola is considered to be the inventor of the first practical mobile phone. On April 3, 1973, Martin placed a call to rival Joel Engel, head of research at AT&T's Bell Labs, while walking the streets of New York City talking on the first Motorola DynaTAC prototype.
2. 3. 4. 5.
In 1940s Motorola developed a backpacked two-way radio, the Walkie-Talkie and a large hand-held two-way radio for the US military. The same technology developed further and produced the mobile phone that we know today. In 1946 USSR (Russia) successfully tested their version of a radio mobile phone mounted inside a car. The modern handheld cell phone era began in 1973 when Motorola invented the first cellular portable telephone to be commercialised, known as Motorola DynaTAC 8000X. On October 13, 1983, the pilot commercial cellular system of Illinois Bell begins operating in Chicago. The second pilot system run by ARTS in partnership with Motorola begins operation in Baltimore/Washington on December 16, 1983.

The Motorola StarTac was the first phone in the world with Vibrating alert function. It was unveiled in North America on January 3, 1996. StarTACs remained popular until the early 2000s. The Sharp J-SH04 was the industry's first mobile phone to feature an integrated 110,000-pixel CMOS image sensor for taking digital photos (camera mobile phone).
10. By 2003 or 2004 Blackberry begun to take the market by storm. The phone were optimized for wireless email communication. GPRS could provide data rates from 56 kbit/s up to 114 kbit/s. It can be used for services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access. 11. On January 9, 2007 Apple unveiled the iPhone to the public.
