Through his experiments it was established that hydrogen is the lightest

1766 to the Royal Society. Subsequently, he discovered the composition of waterof the known gases The results were published in the communication Factitious Airs, presented in 1766 to the Royal Society. He later discovered the composition of the natural water, stating that "it is composed of dephlogisticated air (oxygen) bound to phlogiston (hydrogen)".

1774 - Joseph Priestley discovers the oxygen and shows that the air is formed by different gases Priestley's family moved to a house next to a brewery and he became interested in the gas bubbling in this company. This discovery occurred when heated HgO, mercury monoxide, with which it obtained two vapors, one is condensed in mercury droplets (Hg). To that gas he picked it up in a container, observing that it increased the brilliance of a flame and that if it introduced live mice, they became very active and lived longer. Priestley inhaled from this gas and felt comfortable. A this gas, called it dephlogisticated air, but it was oxygen by nature. He was the first person to use the oxygen mask. Priestley communicated his observations to the French chemist Antoine Laurent de Lavoisier, who repeated the experiments, thus demonstrating that he was in the air and in the water, pointing out his role in respiration and combustion

1962 - Laser Diode

The first to demonstrate coherent light emission from a semiconductor diode (the first laser diode), is widely acknowledged to have been Robert N. Hall and his team at the General Electric research center in 1962.

1962- William Armistead and S. Donald Stookey of Corning Glass Works invent light-sensitive (photochromic) glass.

Modern photochromic lenses tend to be plastic and instead of silver chemicals they contain organic (carbon-based) molecules called naphthopyrans that react to light in a slightly different way: they subtly change their molecular structure when ultraviolet light strikes them. In this altered form, they soak up more ordinary light as it tries to pass by (technically, we say they have a different absorption spectrum), which is what makes the lenses darken. Imagine lots of molecules suddenly darkening inside a clear lens. It's a bit like closing the blinds in front of your window on a sunny day: as the slats turn, they progressively block out more and more light.

1962 - The first SQUID superconducting quantum interference device is invented

A SQUID (for superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops containing Josephson junctions.

1963 - The first balloon embolectomy catheter is invented by Thomas Fogarty.

Thomas Fogarty invented the "medical industry standard" balloon embolectomy catheter. Patented in 1963, this inflated balloon extraction technique revolutionized surgical embolectomy procedures. The Foley catheter is a rubber tube with a balloon tip named after it's inventor. After insertion into the bladder via the urethra, the tip is filled using a syringe with sterilized liquid or air, in order to keep the catheter in place. This type of catheter allows for continuous draining of the bladder, important during and after surgery.

1965 - A bulletproof nylon fabric, Kevlar, is invented at DuPont

Kevlar® or polyparaphenylene terephthalamide is a polyamide synthesized for the first time in 1965 by Polish-American chemist Stephanie Kwolek (1923-2014), who worked for DuPont. The obtaining of the fibers of Kevlar was complicated, emphasizing the contribution of Herbert Blades, that solved the problem of which solvent to use for the processing.

1965 - James Russell invents the compact disk

A compact disk (cd) is a popular form of digital storage media used for computer files, pictures, and music. The plastic platter is read and written to by a laser in a CD drive. It comes in several varieties including CD-ROM, CD-R, and CD-RW. James Russell invented the compact disk in 1965. James Russell was granted a total of 22 patents for various elements of his compact disk system. However, the compact disk did not become popular until it was mass manufactured by Philips in 1980.

Introduced by Cambridge Instruments

1970 CE - 1985 CE

1970s (Late)			Arthroscope introduced Advances in fiber-optics technology give surgeons a view into joints and other surgical sites through an arthroscope, an instrument the diameter of a pencil, containing a small lens and light system, with a video camera at the outer end. Used initially as a diagnostic tool prior to open surgery, arthroscopic surgery, with its minimal incisions and generally shorter recovery time, is soon widely used to treat a variety of joint problems.
1970s			Digital seismology The introduction of digital seismology in oil exploration increases accuracy in locating underground pools of oil. The technique of using seismic waves to look for oil is based on determining the time interval between the sending of a sound wave (generated by an explosion, an electric vibrator, or a falling weight) and the arrival of reflected or refracted waves at one or more seismic detectors. Analysis of differences in arrival times and amplitudes of the waves tells seismologists what kinds of rock the waves have traveled through.
1970s			Mud pulse telemetry Teleco, Inc., of Greenville, South Carolina, and the U.S. Department of Energy introduce mud pulse telemetry, a system of relaying pressure pulses through drilling mud to convey the location of the drill bit. Mud pulse telemetry is now an oil industry standard, saving millions of dollars in time and labor.
	1970		Optical fibers that meet purity standards Corning Glass Works scientists Donald Keck, Peter Schultz, and Robert Maurer report the creation of optical fibers that meet the standards set by Kao and Hockham. The purest glass ever made, it is composed of fused silica from the vapor phase and exhibits light loss of less than 20 decibels per kilometer (1 percent of the light remains after traveling 1 kilometer). By 1972 the team creates glass with a loss of 4 decibels per kilometer. Also in 1970, Morton Panish and Izuo Hayashi of Bell Laboratories, along with a group at the Ioffe Physical Institute in Leningrad, demonstrate a semiconductor laser that operates continuously at room temperature. Both breakthroughs will pave the way toward commercialization of fiber optics.

1970 The floppy disk (8 in.) is invented by Alan Shugart at IBM.

1970s		Fuel prices escalate, driving demand for fuel-efficient cars Fuel prices escalate, driving a demand for fuel-efficient cars, which increases the sale of small Japanese cars. This helps elevate the Japanese automobile industry to one of the greatest in the world.
1970s		Aswan High Dam The Aswan High Dam construction is completed, about 5 kilometers upstream from the original Aswan Dam (1902). Known as Saad el Aali in Arabic, it impounds the waters of the Nile to form Lake Nasser, the world’s third-largest reservoir, with a capacity of 5.97 trillion cubic feet. The project requires the relocation of thousands of people and floods some of Egypt’s monuments and temples, which are later raised. But the new dam controls annual floods along the Nile, supplies water for municipalities and irrigation, and provides Egypt with more than 10 billion kilowatt-hours of electric power every year.
1970		The first CD-ROM patented James T. Russell, working at Battelle Memorial Institute's Pacific Northwest Laboratories in Richland, Washington, patents the first systems capable of digital-to-optical recording and playback. The CD-ROM (compact disc read-only memory) is years ahead of its time, but in the mid-1980s audio companies purchase licenses to the technology. (See computers.) Russell goes on to earn dozens of patents for CD-ROM technology and other optical storage systems.

Used to guide the placement of instruments or treatments, CAT eventually becomes the primary tool for diagnosing brain and spinal disorders. (In 1979, Hounsfield and Cormack are awarded the Nobel Prize in physiology or medicine.)
1972		MRI adapted for medical purposes Using high-speed computers, magnetic resonance imaging (MRI) is adapted for medical purposes, offering better discrimination of soft tissue than x-ray CAT and is now widely used for noninvasive imaging throughout the body.

1972		Pioneer 10 sent to the outer solar system Pioneer 10, the first mission to be sent to the outer solar system, is launched on March 2 by an Atlas-Centaur rocket. The spacecraft makes its closest approach to Jupiter on December 3, 1973, after which it is on an escape trajectory from the Solar System. NASA launches Pioneer 11 on April 5, 1973, and in December 1974 the spacecraft gives scientists their closest view of Jupiter, from 26,600 miles above the cloud tops. Five years later Pioneer 11 makes its closest approach to Saturn, sending back images of the planet’s rings, and then heads out of the solar system in the opposite direction from Pioneer 10. The last successful data acquisitions from Pioneer 10 occur on March 3, 2002, the 30th anniversary of its launch date, and on April 27, 2002. Its signal is last detected on January 23, 2003, after an uplink is transmitted to turn off the last operational experiment.

1974		Energy Reorganization Act of 1974 The Energy Reorganization Act of 1974 splits the Atomic Energy Commission into the Energy Research and Development Administration (ERDA) and the Nuclear Regulatory Commission (NRC). ERDA’s responsibilities include overseeing the development and refinement of nuclear power, while the NRC takes up the issue of safe handling of nuclear materials.
1974		Texas Instruments introduces the TMS 1000 Texas Instruments introduces the TMS 1000, destined to become the most widely used computer on a chip. Over the next quarter-century, more than 35 different versions of the chip are produced for use in toys and games, calculators, photcopying machines, appliances, burglar alarms, and jukeboxes. (Although TI engineers Michael Cochran and Gary Boone create the first microcomputer, a four-bit microprocessor, at about the same time Intel does in 1971, TI does not put its chip on the market immediately, using it in a calculator introduced in 1972.)

1975 First home computer is marketed to hobbyists

The Altair 8800, widely considered the first home computer, is marketed to hobbyists by Micro Instrumentation Telemetry Systems. The build-it-yourself kit doesn’t have a keyboard, monitor, or its own programming language; data are input with a series of switches and lights. But it includes an Intel microprocessor and costs less than $400. Seizing an opportunity, fledgling entrepreneurs Bill Gates and Paul Allen propose writing a version of BASIC for the new computer. They start the project by forming a partnership called Microsoft.

U.S. military begins using fiber optics

The U.S. military begins using fiber optics to improve communications systems when the navy installs a fiber-optic telephone link on the USS Little Rock. Used to transmit data modulated into light waves, the specially designed bundles of transparent glass fibers are thinner and lighter than metal cables, have greater bandwidth, and can transmit data digitally while being less susceptible to interference. The first commercial applications come in 1977 when AT&T and GTE install fiber-optic telephone systems in Chicago and Boston. By 1988 and 1989, fiber-optic cables are carrying telephone calls across the Atlantic and Pacific Oceans.

1976 - Common channel interoffice signaling

AT&T introduces common channel interoffice signaling, a protocol that allows software-controlled, networked computers or switches to communicate with each other using a band other than those used for voice traffic. Basically a dedicated trunk, the network separates signaling functions from the voice path, checks the continuity of the circuit, and then relays the information.

1977 NASA launches two Mars space probes

NASA launches two Mars space probes, Viking 1 on August 20 and Viking 2 on November 9, each consisting of an orbiter and a lander. The first probe lands on July 20, 1976, the second one on September 3. The Viking project’s primary mission ends on November 15, 11 days before Mars’s superior conjunction (its passage behind the Sun), although the two spacecraft continue to operate for several more years. The last transmission reaches Earth on November 11, 1982. After repeated efforts to regain contact, controllers at NASA’s Jet Propulsion Laboratory close down the overall mission on May 21, 1983.

Public Utility Regulatory Policies Act

Congress passes the Public Utility Regulatory Policies Act (PURPA), which spurs the growth of nonutility unregulated power generation. PURPA mandates that utilities buy power from qualified unregulated generators at the "avoided cost"—the cost the utility would pay to generate the power itself. Qualifying facilities must meet technical standards regarding energy source and efficiency but are exempt from state and federal regulation under the Federal Power Act and the Public Utility Holding Company Act. In addition, the federal government allows a 15 percent energy tax credit while continuing an existing 10 percent investment tax credit.

What are non-Newtonian materials?

Ketchup, nail polish, toothpaste, whipped cream, cornstarch, blood, face cream, silly-putty, paint, and custard—what do these things have in common? Apparently nothing! In fact, they're all examples of non-Newtonian fluids. In everyday terms, they get either more viscous (thicker and less runny) or less viscous (thinner and more runny) if you push and poke them around a bit. Some of them are shear-thinning (they get less viscous), others are shear-thickening (getting more viscous) when you push them about:

Shear thinning: Ketchup, toothpaste, blood, paint, nail polish, whipped cream, and face-cream start off relatively thick and viscous but become more runny if you subject them to forces. Shear thickening: Cornstarch, custard, many soups, and silly-putty work the opposite way. They thicken up when you subject them to forces. Some non-Newtonian materials are permanently changed by applied forces: custard stays thick, for example. Others are changed only temporarily and revert back to their original form when the force is removed. Ketchup thins when you shake it but thickens up again once it's sitting on your plate. Toothpaste thickens and thins repeatedly: it's thick inside the tube, thins and flows when you squeeze it, thickens back into a gel once it's sitting on your brush, and thins again when you brush it over your teeth

-Computers

A pioneering low-cost laptop for developing countries called OLPC is announced by MIT computing pioneer Nicholas Negroponte.

Over the last few years, they've worked to create a trimmed-down, low-cost laptop suitable for people who live in developing countries where electricity and telephone access are harder to find. Their project is known as OLPC: One Laptop Per Child.

What's different about the OLPC?

In essence, an OLPC computer is no different from any other laptop: it's a machine with input, output, memory storage, and a processor—the key components of any computer. But in OLPC, these parts have been designed especially for developing countries.

Here are some of the key features:

Low cost: OLPC was originally designed to cost just $100. Although it failed to meet that target, it is still cheaper than most traditional laptops. Inexpensive LCD screen: The hi-tech screen is designed to work outdoors in bright sunlight, but costs only $35 to make—a fraction of the cost of a normal LCD flat panel display. Trimmed down operating system: The operating system is like the conductor of an orchestra: the part of a computer that makes all the other parts (from the processor chip to the buttons on the mouse) work in harmony. Originally, OLPC used only Linux (an efficient and low-cost operating system developed by thousands of volunteers), but it began offering Microsoft Windows versions as an alternative in 2008. Wireless broadband: In some parts of Africa, fewer than one person in a hundred has access to a wired, landline telephone, so dialup Internet access via telephone would be no use for OLPC users. Each machine's wireless chip will allow it to create an ad-hoc network with other machines nearby—so OLPC users will be able to talk to one another and exchange information effortlessly. Flash memory: Instead of an expensive and relatively unreliable hard drive, OLPC uses a huge lump of flash memory—like the memory used in USB flash memory sticks and digital camera memory cards. Own power: Home electricity supplies are scarce in many developing countries, so OLPC has a hand crank and built-in generator. One minute of cranking generates up to 10 minutes of power. Is OLPC a good idea?

Anything that closes the digital divide, helping poorer children gain access to education and opportunity, must be a good thing. However, some critics have questioned whether projects like this are really meeting the most immediate needs of people in developing countries. According to the World Health Organization, around 1.1 billion people (18 percent of the world's population) have no access to safe drinking water, while 2.7 billion (a staggering 42 percent of the world's population) lack basic sanitation. During the 1990s, around 2 billion people were affected by major natural disasters such as floods and droughts. Every single day, 5000 children die because of dirty water—that's more people dying each day than were killed in the 9/11 terrorist attacks.

With basic problems on this scale, it could be argued that providing access to computers and the Internet is not a high priority for most of the world's poorer people. Then again, education is one of the most important weapons in the fight against poverty. Perhaps computers could provide young people with the knowledge they need to help themselves, their families, and communities escape a life sentence of hardship?

- Computers - Touchscreens "Apple releases its touchscreen tablet computer, the iPad." - 3D Television "3D TV starts to become more widely available."

There are several different ways of making a 3D TV, but all of them use the same basic principle: they have to produce two separate, moving images and send one of them to the viewer's left eye and the other to the right. To give the proper illusion of 3D, the left eye's image mustn't be seen by the right eye, while the right eye's image mustn't be seen by the left.

Anaglyph: You have to wear eye glasses with colored lenses so your brain can fuse together the partly overlapping red and cyan pictures on the screen. Polarizing: You wear lenses that filter light waves in different ways so each eye sees a different picture. Active-shutter: The left and right lenses of your glasses are fitted with liquid crystals that effectively "open" and "close" at high speed, in rapid alternation, so your two eyes view separate images (frames) shown on the same screen. Lenticular: You don't need glasses with this system. Instead, a row of plastic lenses in front of the screen bends slightly different, side-by-side images so they travel to your left and right eyes. You must sit in the right place to see a 3D image.
