By 1524, pocket watches produced by Peter Henlein, spread across Europe. With the usage of screws, since 1550 onwards, pocket watch gradually become flatter otherwise it used to be cylindrical. 1675 was the year when new fashion style emerged and hence pocket watches were so small that it could be carried in the shirt pockets also. Charles II of England has popularized this new way of carrying watches across entire Europe and North America.

Martin Cooper was born on December 26, 1928 in Chicago to the parents of Arthur and Mary Cooper. After graduating from the Illinois Institute of Technology with his Masters and bachelors Degree in Electrical Engineering in 1950 (Martin Cooper&Leard), he joined the navy for 4 years. He was fighting in World War II before Motorola offered him a job. As he worked at Motorola, he was inspired. Star Trek inspired him. On the show they used small, hand-held communication devices.

A portable device that would replace wired telecommunication system forced to work in this direction. And From 1972 he worked upon this. In 1973, he succeeded. Martin made first mobile call on April 3, 1973.

Weight of the phone was 2.5 pounds. It was 9 inches long and 5 inches in height. He nicknamed it "The Brick". It used to take more than 10 hours to charge and one could able to talk only 30 minutes. In front of reporters, he made first wireless telephonic call from handheld subscriber equipment to Dr. Joel S. Engel of Bell Labs.

However, 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.

Where as 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 began operating in Chicago. The second pilot system ran by ARTS in partnership with Motorola begins operation in Baltimore/Washington on December 16, 1983. And so on, By 1984, Washington, DC has two competing cellular providers. 

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.

Who invented television?

Have you ever wondered who invented television? Then this article is going to help you to know who are the inventors behind the television.

Marcony's invention of wireless telegraphy radio sparked an imagination among scientists alike sound, visuals can also be transmitted from one point to the another. This opened path towards the invention of television. However behind television invention, there are multiple names float around.

George Carey [Image Source: Wikipedia]

George Carey was the person whose name is documented to send components of pictures over a series of multiple circuits. However, W. E Sawyer, suggested the possibility of sending an image over a single wire by rapidly scanning parts of the picture in succession.

On December 2, 1992 Edwin Belin, an Englishman, deomonstrated a mechanical scanning device that was the first version of modern television.

He had held the patent for the transmission of photographs by wire, Fiber Optics and also through radar. Belin's mechanical scanning device captured flashes of light and sent them at a selenium element connected to an electronic device that produced sound waves. Then the sound waves were received at another location which were remodulated back into flashes of light on a mirror.

So far at this point, the concept of television was established but still electronic scanning of images yet to be invented. In this race, two names have been conflicting over the real inventor of modern television.

Vladimir Kosma Zworykin, a Russian Born American Inventor and Philo Taylor Farnsworth, a farm boy from the state of Utah. Both worked on same issue over same time period. Zworykin had a patent but Farnsworth had a picture.

Meanwhile, John Logie Baird, a Scottish Engineer cum Entrepreneur successfully achieved first transmission of simple face shapes in 1924 using mechanical television.

Toy Train Shimla Toy Train Travel Information Kalka Shimla Railway

Toy Train Shimla - Journey in a toy train is something else which no word can helpful to express the joy. Kalka Shimla Railway runs toy train between capital of Himachal Pradesh Shimla to Kalka of Chandigarh. The Kalka to Shimla railway is a 2 ft 6 inch or 762 mm narrow gauge railway in North India which traverses a mostly mountainous route from Kalka to Shimla. It is known for dramatic views of the hills and surrounding villages.

The railway was built under the direction of Herbert Septimus Harington between 1898 and 1903 to connect Shimla, the summer capital of India during the British Raj, with the rest of the Indian rail system. Its early locomotives were manufactured by Sharp, Stewart and Company. Larger locomotives were introduced, which were manufactured by the Hunslet Engine Company. Diesel and diesel-hydraulic locomotives began operation in 1955 and 1970, respectively. On 8 July 2008, UNESCO added the Kalka–Shimla railway to the mountain railways of India World Heritage Site.

Toy Train Shimla History

Shimla (then spelt Simla), which was settled by the British shortly after the first Anglo-Gurkha war, is located at 7,116 feet (2,169 m) in the foothills of the Himalayas. The idea of connecting Shimla by rail was first raised by a correspondent to the Delhi gazette in November 1847. Shimla became the summer capital of British India in 1864, and was the headquarters of the Indian army.

This meant that twice a year it was necessary to transfer the entire government between Calcutta and Shimla by horse and ox drawn carts. In 1891 the 1,676 mm (5 ft 6 in) broad-gauge Delhi–Kalka line opened, which made the construction of a branch line up to Shimla feasible. The earliest survey was made in 1884 followed by another survey in 1885. Based on these two surveys, a project report was submitted in 1887 to the government of British India. Fresh surveys were made in 1892, and 1893 which lead to four alternate schemes being suggested - two adhesion lines 67.25 mi (108.23 km) and 69.75 mi (112.25 km) long and two rack lines. Fresh surveys were again made in 1895 from Kalka to Solan with a view to determine whether a 1 in 12 rack or 1 in 25 adhesion line should be chosen. After much debate an adhesion line was chosen in preference to a rack system.

Construction of the Kalka–Shimla railway on 2 ft (610 mm) narrow-gauge tracks was begun by the privately funded Delhi-Ambala-Kalka Railway Company following the signing of a contract between the secretary of state and the company on 29 June 1898. The contract specified that the line would be built without any financial aid or guarantee from the government. The government however provided the land free of charge to the company. The estimated cost of 8,678,500 rupees doubled by the time the line was opened. The Chief Engineer of the project was H.S. Herlington.
