The First Manned Flight
On December 17, 1903, <a href=http://http://www.eyewitnesstohistory.com/wright.htm >Orville Wright </a>piloted the first powered airplane 20 feet above a wind-swept beach in North Carolina. The flight lasted 12 seconds and covered 120 feet. Three more flights were made that day with Orville's brother, Wilbur, who piloted the record flight lasting 52 seconds and a distance of 852 feet. -
Sonar
Lewis Nixon invented the very first Sonar type listening device in 1906, as a way of detecting icebergs. Interest in Sonar was increased during World War I when there was a need to be able to detect submarines. Sonar is a system that uses transmitted and reflected underwater sound waves to detect and locate submerged objects or measure the distances underwater. -
Ford Model T
The Model T was introduced on Oct. 1, 1908. It had a 20-horsepower, four-cylinder engine, reached a top speed of about 45 miles per hour, got about 13 to 21 miles per gallon of gasoline and weighed 1,200 pounds. It was the ninth of Henry Ford's production cars.More than 15,000,000 Model T's were built and sold. Led to the invention of the assembly line. -
The Band Aid
In 1921, Earle Dickson took a piece of gauze and attached it to the center of a piece of tape, and then covered the product with crinoline to keep it sterile, inventing the band aid. By 1924, Band-Aids were machine made, sold sterilized in 1939, and made with vinyl tape in 1958. -
The Polygraph Machine Invented by John Larson
John Larson, a University of California medical student, invented the polygraph machine in 1921. This invention was used in police interrogation and investigation since 1924. The lie detector is still controversial among psychologists, and is not always judicially acceptable. The name polygraph comes from the fact that the machine records several different body responses simultaneously as the individual is questioned. -
Penicillin Was Created
In 1928, bacteriologist Alexander Fleming made a coincidental discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin. -
Sliced Bread
In 1928, a man named Otto Frederick Rohwedder invented the Rohwedder Bread Slicer. Rohwedder began working on inventing a bread slicer in 1912. Unfortunately, bakers scoffed at Rohwedder's early slicers; the bakers were sure that the bread would quickly go stale if pre-sliced. In order to prevent the bread from being stale, Rohwedder wrapped it in a wax paper wrap to keep it fresh. Sliced Bread has been the coolest invention ever since. -
First Electronic Computer with Stored Memory is Invented
The modern computer was born on 21 June 1948, when the University of Manchester's Small-Scale Experimental Machine, nicknamed the 'Baby', successfully executed its first program. Designed and built by F. C. Williams and Tom Kilburn*, the Baby kept only 1,024 bits in its main store, but it was the first computer to store a changeable user program in electronic memory and process it at electronic speed. -
Sputnik I is launched by the Soviet Union
The Soviet Union successfully launched The world's first artificial satellite was about the size of a beach ball, weighed only 183.9 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S.S.R space. http://goo.gl/3JjrN -
Explorer 1
was the first satellite launched by the United States when it was sent into space on January 31, 1958. Following the launch of the Soviet Union's Sputnik 1 on October 4, 1957. -
United States Moon Landing
The first steps by humans on another planet were taken by Neil Armstrong and Buzz Aldrin on July 20, 1969. The astronauts also returned to Earth the first samples from another planet. Apollo 11 achieved its primary mission to perform a manned lunar landing and return the mission safely to Earth,and paved the way for the Apollo lunar landing missions to follow. -
Microprocessor
In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004, invented by Intel engineers Federico Faggin, Ted Hoff, and Stanley Mazor. After the invention of integrated circuits revolutionized computer design. The Intel 4004 chip took the integrated circuit down one step further by placing all the parts that made a computer think on one small chip. Programming intelligence into inanimate objects had now become possible. -
Atari
The original Atari, Inc. was founded in 1972 by Nolan Bushnell and Ted Dabney. It was a pioneer in arcade games, home video game consoles, and home computers. The company's products, such as Pong and the Atari 2600, helped define the computer entertainment industry from the 1970s to the mid-1980s. -
Apple II Computer introduced
The Apple II was advertised as a "complete, ready to use computer, " and had an integrated keyboard with ports for a separate colour display and a cassette recorder for data storage. Marketed towards consumers rather than computing hobbyists. -
Microsoft Windows
Microsoft Windows was a next-generation operating system that would provide a graphical user interface (GUI) and a multitasking environment for IBM computers. It took Microsoft 2 years after the promised date to send out their program, Windows. -
World Wide Web
World Wide Web (WWW), or known as The Web, the leading information retrieval service of the Internet. The Web gives users access to a vast array of documents that are connected to each other by means of hypertext or hypermedia links ex., hyperlinks, electronic connections that link related pieces of information in order to allow a user easy access to them.
