				<description>1752: Benjamin Franklin finds electricity in lightening while flying a kite in a storm.





Benjamin Franklin's electricity experiments lead him to a valuable application -- the lightning rod, which when placed at the apex of a barn, church steeple, or other structure, conducts lightning bolts harmlessly into the ground.

				<description>1797 Interchangeable Parts
Eli Whitney contracts to manufacture 10,000 muskets for the U.S. Army. At the time, an entire musket would be made by a single person, without standardized measurements. Whitney divided the labor into several discrete steps and standardized parts to make them interchangeable.

				<description>1862 Battle of the Ironclads
For the first time, two armored ships battle each other at sea. The Union Monitor, designed from scratch by John Ericsson, features a two-cannon revolving turret and eight-inch plate armor. The Confederate Merrimac, a wooden hulled ship hastily outfitted with iron plates, holds it own against the Monitor. The two battle to a draw.

				<description>Wilhelm Roentgen discovered x-rays. While studying the luminescence (light) produced by cathode rays, Roentgen had placed a cathode ray tube in a box in a darkened room. (A cathode ray tube is a vacuum tube in which a cathode, or negatively charged electrode, sends out a stream of electrons.) A sheet of paper coated with a barium compound happened to be near the box. Roentgen noticed that when the tube was switched on in the closed box, the paper glowed brilliantly. He concluded that some sort of ray had penetrated the box and caused the paper to glow. Because he didn't know what they were or where they came from, he called them x-rays (x for unknown). He also noticed the rays caused photographic plates, even when wrapped in paper, to darken or fog. This led him to take x-ray photographs of objects such as his hand. The photographs revealed the inner structure of the objects.

The world immediately appreciated the medical potential of x-rays. X-rays revolutionized medicine because they enabled doctors to see the interior of the body without surgery. Within five years of the discovery, for example, the British Army began using a mobile x-ray unit to locate bullets and shrapnel in wounded soldiers in the Sudan.

				<description>Albert Einstein developed a theory about the relationship of mass and energy. The formula, E=mc[2], is probably the most famous outcome from Einstein's special theory of relativity. The formula says energy (E) equals mass (m) times the speed of light (c) squared. In essence, it means mass is just one form of energy. Since the speed of light squared is an enormous number (186,000 miles per second)[2], a small amount of mass can be converted to a phenomenal amount of energy. Or, if there's a lot of energy available, some energy can be converted to mass and a new particle can be created. Nuclear reactors, for instance, work because nuclear reactions convert small amounts of mass into large amounts of energy.

				<description>On August 2, Albert Einstein sent a letter to President Roosevelt informing him of German atomic research and the potential for a bomb:

"Some recent work...leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future...that it may become possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power and large quantities of new radium-like elements would be generated.... This new phenomenon would also lead to the construction of bombs, and it is conceivable -- though much less certain -- that extremely powerful bombs of a new type may thus be constructed. A single bomb of this type...might very well destroy the whole port together with some of the surrounding territory."

Einstein drafted the letter with the help of Hungarian physicist Leo Szilard, one of many scientists who had fled Europe to escape Nazi and Fascist repression. Szilard was a vocal advocate of a U.S. program to develop bombs based on the latest findings in nuclear physics. In the letter, they encouraged Roosevelt to fund American atomic research. This letter prompted Roosevelt to form a special committee to investigate the military implications of atomic research. Roosevelt approved uranium research in the United States in October 1939. This was the first decision among many that led to establishment of the Manhattan Project (see September 1942).

				<description>On the morning of December 7, 1941, Japanese forces launched a surprise attack on the U.S. naval base at Pearl Harbor, Hawaii. Nineteen U.S. ships were sunk or damaged, and 3,000 Americans lost their lives. Japan also attacked Guam, Wake Island, the Philippines, and other strategic points in the Pacific at the same time Pearl Harbor was attacked. In his address to a stunned nation, President Roosevelt called December 7 "a date that will live in infamy." On December 8, the U.S. Congress declared war against Japan. Two days after Pearl Harbor, President Roosevelt told the nation, "We are going to win the war, and we are going to win the peace that follows."

				<description>To finance the development of his "six shooter," Samuel Colt traveled the lecture circuit, giving demonstrations of laughing gas. Colt's new weapon failed to catch on, and he went bankrupt in 1842 at age 28. He reorganized and sold his first major order to the War Department during the Mexican War in 1846, and went on to become rich.

				<description>1942 U.S. Manhattan Project begins in order to develop the first atomic bomb.  The anti-tank rocket, or bazooka, is invented.  Before the bazooka, only anti-tank grenades or "elephant guns" would damage well-armored tanks but even these performed poorly.  Aircraft carriers become the major offensive arm of the Navy.

				<description>RAND Paul Baran, of the RAND Corporation (a government agency), was commissioned by the U.S. Air Force to do a study on how it could maintain its command and control over its missiles and bombers, after a nuclear attack. This was to be a military research network that could survive a nuclear strike, decentralized so that if any locations (cities) in the U.S. were attacked, the military could still have control of nuclear arms for a counter-attack.

Baran's finished document described several ways to accomplish this. His final proposal was a packet switched network.

"Packet switching is the breaking down of data into datagrams or packets that are labeled to indicate the origin and the destination of the information and the forwarding of these packets from one computer to another computer until the information arrives at its final destination computer. This was crucial to the realization of a computer network. If packets are lost at any given point, the message can be resent by the originator."

				<description>In 1969 the US Government, DoD (Department of Defense to be specific) developed ARPANET.  They use this technology to allow various computers within different sections of the military and government that work on different systems to share information with one another.  This is the first network.  By the end of 1969, four host computers were connected together into the initial ARPANET.  These computers were located at 4 colleges: UCLA, Stanford, University of California, and University of Utah.  Within 2 years, there  were 23 nodes of this network including MIT, NASA, and Harvard.  The beginning of the Internet was seen by 1971.  By 1972, ARPA is renamed DARPA.

				<description>The ARPANET was divided into two networks: MILNET and ARPANET. MILNET was to serve the needs of the military and ARPANET to support the advanced research component, Department of Defense continued to support both networks.

Upgrade to CSNET was contracted to MCI. New circuits would be T1 lines,1.5 Mbps which is twenty-five times faster than the old 56 Kbps lines. IBM would provide advanced routers and Merit would manage the network. New network was to be called NSFNET (National Science Foundation Network), and old lines were to remain called CSNET.

				<description>1916: Enigma is created to encode messages at the end of WW I







One of the milestones in the history of cryptology is the invention of an electro-mechanical
cryptographic system called Enigma (see Figure 1). The concept on which it was based was
introduced in 1915 by the American Edward Hebern (Harper, 1999). Hebern devised a machinegenerated
code by adapting a newly produced electric typewriter. The letters in the new
machines were rearranged so that the printed letters would be different from the letters on the
keyboard. He simply replaced one letter with another so that the word CRYPTOGRAPHY would
be printed FGTDAEJGYDWT. This operation was of course easily reversible with an
appropriate set of switches. However, code generated using this type of machine was easy to
decode since all Western languages have a characteristic repetition rate of letters, whatever the
text, and could be broken using frequency analysis. Hebern realised this and devised another
machine with rotors, which switched the connections of the electronic typewriter each time a key
was pressed (Harper, 1999). Hebern eventually sold this patented Electric Coding Machine to the
US Navy in 19281.

				<description>Flying from July 1963 to June 1967, the KH-7 -- carrying special Kodak-built camera gear -- became the intelligence community's first high-resolution imaging satellite. This spacecraft series was successful on 34 of 38 missions, with 30 satellites returning film.

The General Electric-built KH-7 was boosted into orbit atop rocketry produced by Lockheed. The whole program was managed by the Air Force component of the National Reconnaissance Office (NRO).

				<description>The first e-mail program was created by Ray Tomlinson of BBN.

The Advanced Research Projects Agency (ARPA) was renamed The Defense Advanced Research Projects Agency (or DARPA)

ARPANET was currently using the Network Control Protocol or NCP to transfer data. This allowed communications between hosts running on the same network.

				<description>Internet Activities Board (IAB) was created in 1983.

On January 1st, every machine connected to ARPANET had to use TCP/IP. TCP/IP became the core Internet protocol and replaced NCP entirely.

The University of Wisconsin created Domain Name System (DNS). This allowed packets to be directed to a domain name, which would be translated by the server database into the corresponding IP number. This made it much easier for people to access other servers, because they no longer had to remember numbers.

				<description>1775 	First submarine used in war.

In 1777, The submarine Turtle was built by American inventor John Bushnell and operated by Sergeant Ezra Lee. It carried an explosive device designed to blow a hole in the hull of an enemy ship. Bushnell had attached an auger to the Turtle which was operated by a crank from the inside. The idea was to drill a hole in the enemy hull and attach the bomb, which would be given a long enough fuse to allow the little sub to get away safely. The bomb worked fine on its first trial, scaring the crew of the British frigate Eagle out of their wits. The auger and drill did not, however, and the bomb exploded noisily but harmlessly on the surface. The frigate's copper sheathed bottom, intended to protect the ship from teredo worms, was too hard for the drill to penetrate.

				<description>1955 Nuclear Submarine
The Nautilus, the first nuclear submarine, revolutionizes naval warfare. Conventional submarines need two engines: a diesel engine to travel on the surface and an electric engine to travel submerged, where oxygen for a diesel engine is not available. The Nautilus, the first nuclear sub, can travel many thousands of miles below the surface with a single fuel charge.

				<description>1967 (F) Bell Helicopter experiments with HMDs with input from servo-controlled cameras [Bell Helicopter]
    Bell Helicopter Company performed several early camera-based augmented-reality systems. In one, the head-mounted display was coupled with an infrared camera that would give military helicopter pilots the ability to land at night in rough terrain. An infrared camera, which moved as the pilot's head moved, was mounted on the bottom of a helicopter. The pilot's field of view was that of the camera. See http://www.sun.com/960710/feature3/alice.html for more details.

				<description>	Scotsman John Napier (1550-1617) published a paper outlining his discovery of the logarithm. Napier also invented an ingenious system of moveable rods (referred to as Napier's Rods or Napier's bones). These allowed the operator to multiply, divide and calculate square and calculate cube roots by moving the rods around and placing them in specially constructed boards.

				<description>1822, Charles Babbage begins working on a mechanical device that was far superior to the Pascal machine, but lacking the resources to build such a device, construction is never completed.

1833, Charles Babbage stopped work on his mechanical calculator it to move on to another project that would calculate 'yes / no' analytical or conditional functions beyond simple addition.  This system was designed to use 'holes punched in paper' as a method of input, but the device was never built beyond the 'plans' to develop it.  These were the first plans developed for a logical calculating computer.

				<description>Marie and Pierre Curie discovered the radioactive elements radium and polonium. Before this discovery, uranium and thorium were the only known radioactive elements. While studying uranium minerals. Marie Curie noticed two minerals were much more radioactive than uranium itself. She and her husband, Pierre, chemically separated the compounds in the minerals and found a substance 400 times more radioactive than uranium. Marie named this substance polonium, after her native country of Poland. The Curies also found one of the uranium minerals contained another element more radioactive than uranium. They named this element radium. The Curies won the 1903 Nobel Prize in physics for these discoveries.

Marie Curie won the Nobel Prize in chemistry in 1910 for obtaining elemental radium in the metallic state. She was the first person to win the Nobel Prize twice.

Soon after the Curies' discoveries, other scientists discovered the radioactive element actinium. By 1912, thirty radioactive elements had been discovered.

				<description>Allen Moshfegh at the Office of Naval Research is the head of the Autonomous Intelligent Network and Systems (AINS), a program that aims to create an operational drone army by the year 2020.

Initiated in 1996 -- and based on a humble spy plane originally used for tracking whales at sea -- researchers are attempting to make this science-fiction scenario a reality. The project has an annual budget of roughly $6 million. Given more aggressive development and increased funding, Moshfegh believes that the technology could be functional well before that date.
