His first innovation after the telephone was the 'photophone,' a device that enabled sound to be transmitted on a beam of light.
Alexander Graham Bell
Alexander Graham Bell (March 3, 1847 – August 2, 1922) was an eminent scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone.
Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first US patent for the telephone in 1876. In retrospect, Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study.
Electronics engineering, or electronic engineering, is an engineering discipline where non-linear and active electrical components such as electron tubes, and semiconductor devices, especially transistors, diodes and integrated circuits, are utilized to design electronic circuits, devices and systems, typically also including passive electrical components and based on printed circuit boards. The term denotes a broad engineering field that covers important subfields such as analog electronics, digital electronics, consumer electronics, embedded systems and power electronics. Electronics engineering deals with implementation of applications, principles and algorithms developed within many related fields, for example solid-state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, electric power control, robotics, and many others.]verification needed[
The Institute of Electrical and Electronics Engineers (IEEE) is one of the most important and influential organizations for electronics engineers.

Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices. The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone, invented in 1880.
An optical communication system uses a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal. When electronic equipment is not employed the 'receiver' is a person visually observing and interpreting a signal, which may be either simple (such as the presence of a beacon fire) or complex (such as lights using color codes or flashed in a Morse code sequence).
The National Geographic Society (NGS), headquartered in Washington, D.C. in the United States, is one of the largest non-profit scientific and educational institutions in the world. Its interests include geography, archaeology and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. The National Geographic Society’s logo is a yellow portrait frame – rectangular in shape – which appears on the margins surrounding the front covers of its magazines and as its television channel logo.
Scottish inventions and discoveries are objects, processes or techniques either partially or entirely invented or discovered by a person born in or descended from Scotland. In some cases, an invention's Scottishness is determined by the fact that it came into existence in Scotland (e.g., animal cloning), by non-Scots working in the country. Often, things that are discovered for the first time are also called "inventions" and in many cases there is no clear line between the two.
The Scots take enormous pride in the history of Scottish invention and discovery. There are many books devoted solely to the subject, as well as scores of websites listing Scottish inventions and discoveries with varying degrees of science.
Volta Laboratory and Bureau
The Reis telephone, was an invention by Philipp Reis inspired by a French article in 1854 (by Charles Bourseul) on how to create microphone-like devices. His first successful work was achieved in October 1861.
The Volta Laboratory, also variously known as the "Alexander Graham Bell Laboratory", the "Bell Carriage House" and the "Bell Laboratory", plus the Volta Bureau, were created in Georgetown, Washington, D.C. by Alexander Graham Bell.
The Volta Laboratory was founded in 1880–1881 with Charles Sumner Tainter and Bell's cousin, Chichester Bell, for the research and development of telecommunication, phonograph and other technologies.
Nathan B. Stubblefield (November 22, 1860 - March 28, 1928) was an American inventor and Kentucky melon farmer. It has been claimed that Stubblefield demonstrated radio in 1892, but his devices seem to have worked by audio frequency induction or, later, audio frequency earth conduction (creating disturbances in the near-field region) rather than by radio frequency radiation for radio transmission telecommunications.
Though there were contemporaneous experiments by others such as William Preece, Stubblefield has been proposed as a claimant for the invention of wireless telephony, or wireless transmission of the human voice, which would, however conflict with the four documented patents for the photophone, invented jointly by Alexander Graham Bell and Charles Sumner Tainter in 1880. The photophone allowed for the transmission of sound on a beam of light, and on June 3, 1880 Bell and Tainter transmitted the world's first wireless telephone message on their newly invented form of telecommunication.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks.
Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV). Newspaper, book and other print publishing are adapting to website technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.
