Benjamin Franklin
Benjamin Franklin lived from 1706 to 1790 and was one of the Founding Fathers of the United States. He made many important contributions in diverse fields including science, politics, and invention. Some of his most notable accomplishments were discovering that lightning is a form of electricity, inventing the lightning rod and bifocals, and conducting experiments that supported the wave theory of light.
Galileo Galilei
Galileo Galilei was an Italian astronomer, physicist and engineer who played a major role in the scientific revolution. Through his telescope observations, he discovered that the moon was not smooth but had mountains and craters, and that Jupiter had moons orbiting it. His observations supported the heliocentric model of the solar system and contradicted the geocentric model advocated by the Catholic Church. Despite his scientific contributions, Galileo was eventually tried by the Inquisition and forced to recant his heliocentric views.
Galileo Galilei
Galileo Galilei was born in Pisa, Italy in 1564. Although his father wanted him to study medicine, Galileo pursued mathematics and began teaching privately after abandoning his medical studies. In 1609, Galileo significantly improved the telescope and began making astronomical observations, discovering the moons of Jupiter, sunspots, and that the earth revolves around the sun. This contradicted the Catholic Church's view, and in 1633 Galileo was tried and sentenced to house arrest for defending the Copernican system, where he remained until his death in 1642.
Archimedes principle
Archimedes' principle states that the buoyant force on an object submerged or partially submerged in a fluid is equal to the weight of the fluid the object displaces. This principle can be used to calculate density and relative density. It also explains why ships and submarines float or sink depending on whether the object's density is greater than, equal to, or less than the fluid it is placed in. Applications of Archimedes' principle include ship building, submarine operations, and how certain aquatic animals and balloons are able to achieve buoyancy.
Archimedes principle
The document discusses buoyancy and how objects float or sink in water. It states that an object's apparent weight is less than its actual weight when submerged due to buoyant force. Buoyant force equals the weight of fluid displaced and is equal to the actual weight minus the apparent weight. A boat made of steel floats because its large size and hollow shape displace a large volume of water, creating enough buoyant force to support the boat's weight, while a solid steel block sinks because it only displaces a small volume of water, resulting in insufficient buoyant force.
Benjamin Franklin powerpoint
Benjamin Franklin was born in 1706 in Boston, Massachusetts. He had little formal schooling but taught himself subjects like geometry and languages. He worked in his brother's printing shop and later opened his own print shop. Franklin wrote Poor Richard's Almanac and published the Pennsylvania Gazette newspaper. He invented bifocals, the lightning rod, the Franklin stove, and more. Franklin served as a representative for the 13 colonies in Europe and signed the Declaration of Independence and Constitution.

New Technology Lecture L11 Connecting People
The history of technology has many lessons on how technology trends evolve over time. Discoveries create opportunities for practical solutions. The foundation for electronic communication as we know today was laid in the 19th century. From 1820 to the turn of the century, innovators made experiments and discoveries.
Morse’s telegraph made Western Union big and powerful. The telegraph proved to be a disruptive technology that changed how wars were fought and how businesses were run. However, the telephone would also prove to be disruptive and destroyed the telegraph business.
At the dawn of the 20th century many believed that there was a market for wireless communication. One was Guglielmo Marconi, who set out to commercialize the technology. Marconi and others created a new market for communication
Bjmc i-i, met, unit-iv, marconi, hertz and radio
Arthur C. Clarke first suggested using satellites for communication in 1945, though it may have seemed outlandish at the time. In 1957, the Soviet Union launched Sputnik, the first satellite, demonstrating the viability of satellite technology. In 1962, the US launched Telstar, allowing live television broadcasts between the US and Europe, including coverage of John F. Kennedy's funeral. This inaugurated an era of global communication via satellite.
History of radio
Guglielmo Marconi is considered the inventor of radio, building on earlier work with radio waves. In the late 1890s, Marconi transmitted the first radio signals and established the first radio factory in England. The radio allowed for wireless communication between soldiers and news/information to be transmitted, including the first radio link between Britain and France. While the Italian government rejected Marconi's initial proposal, his work established radio as an important communication technology.
19th Century Radio & Radio in the Bahamas
The document provides a detailed history of radio communication developments from the 19th century through the early 20th century. It describes key inventions and discoveries that laid the foundation for radio, such as Oersted's discovery of electromagnetism in 1820 and Maxwell's theory of electromagnetic waves in 1860. Pioneers like Marconi, Tesla, and Loomis then conducted early experiments in wireless telegraphy in the late 1800s. By the early 1900s, Marconi had achieved the first transatlantic radio transmission, cementing radio as a means of communication.
Birth of telecommunications
The birth of telecommunications was enabled by four key developments: 1) advances in electromagnetism science, 2) the ability to generate and store electricity, 3) the mechanical devices and infrastructure to transmit electricity, and 4) the creation of Morse code to translate electrical pulses into language. Together, these scientific and technological progressions allowed for the establishment of telegraph lines and marked the beginning of telecommunications.
History of telecommunication
Telecommunication has evolved greatly over time from early methods like drums and smoke signals to modern technologies. Early wired telecommunication systems included the optical telegraph, electrical telegraph, and telephones. Wireless technologies then emerged such as radio, mobile phones, and satellites that enabled telecommunication without wires. Important developments included the first transatlantic telegraph cable connecting Europe and North America, Alexander Graham Bell's invention of the telephone, and the launch of communication satellites that helped establish the internet and cellular networks that dominate telecommunication today.

Guglielmo Marconi is considered the inventor of radio. In the late 1890s, Marconi developed wireless telegraphy, which allowed transmission of Morse code signals over long distances without wires. He demonstrated the value of this technology when he helped save lives after the Titanic disaster in 1912 by alerting nearby ships of the sinking via wireless telegraphy. Throughout the early 1900s, other inventors like Edwin Armstrong continued developing radio technologies, leading to FM radio in the 1930s and the transistor radio in the 1950s. Today, radio remains a popular medium of entertainment and information, now available in various forms including internet and satellite radio.
