Forty Years of the Internet: How the World Changed for Ever

Nowadays, one cannot imagine life without the Internet. Arguably, the web is as revolutionary and ground-breaking invention as things like a printing press, the telegraph, or even the very technology of writing. Thanks to the Internet, billions of people across all over the world can communicate with each other, search for different kinds of information, work, and buy goods by merely using their PCs, Macs, or smartphones.  Although such global popularity and integrity of the Internet largely take its roots from the edge of the 20th and 21st centuries, this technology is much older than one may think. In reality, the web is more than 40 years old, and some technological advancements and ideas, which eventually led to its creation are even older. To help you to investigate the fascinating history of the Internet, our WriteMyEssayOnline team have collected a bunch of exciting facts about the web. The earliest years 1. One may track the Internet to as early as 1957. On that year, the United States Department of Defense decided to establish an Advanced Research Projects Agency (ARPA) in response to the USSR’s launch of the first spacecraft satellite. The main goal of ARPA was to create new projects in science and technology to obtain superiority over their potential foreign competitors. 2. In the early 1960s, the web was born on paper. It started from the United States Air Force request to create technology, which would allow protecting and transferring crucial data in the conditions of a possible nuclear war. In 1962, such a task became theoretically possible. In particular, J. C. R. Licklider of MIT introduced a concept for a global computer network. In the same year, Paul Baran of the Rand Corporation designed a method of dividing information into blocks, which could be sent separately from one computer to another. ARPA was highly interested in both ideas, so the agency invested in them, creating the ARPANET project in 1968. From the ARPANET to the Internet 3. In 1971, the ARPANET was nothing but a network, which connected 23 mini-computers within different universities and research facilities in the USA. In such a way, the network allowed sharing pieces of information regardless of the distance between its users. Two years later, England and Norway were connected to the ARPANET, which now became the first international network. 4. Following the ARPANET, several other computer networks were created in the 1970s. Still, since they used different protocols, each of them can be perceived as a separate system. For instance, Ethernet, developed by Robert Metcalfe connected computers via cables while Tim Truscott and Steve Bellovin invented USENET, a network, which works via a dial-up phone connection. Still, in 1973, Robert Kahn and Vinton Cerf developed the Transmission Control Protocol (TCP), which aimed at linking multiple networks together. Next year, in their notes regarding TCP, Kahn and Cerf coined the term “Internet.” 5. In 1983, the ARPANET connected about 500 hosts, primarily universities and research facilities. At the same time, dial-up networks introduced email communication and became available in most developed countries. With the growing amount of users and different purposes for the network use, there was a need for creating a convenient and efficient way to help the users to find particular information. To address this issue, scholars of the University of Wisconsin created the Domain Name System (DNS), which is still widely used. The first steps towards global access 6. By the mid-1980s, different computer networks were used by many universities across the USA and Europe for research, education, and communication purposes. Similarly, some large companies started to investigate ways of...

Flame retardants -- from plants

Flame retardants are present in thousands of everyday items, from clothing to furniture to electronics. Although these substances can help prevent fire-related injuries and deaths, they could have harmful effects on human health and the environment. Today, scientists report potentially less toxic, biodegradable flame retardants from an unlikely source: plants.

Disappearing act: Device vanishes on command after military missions

A polymer that self-destructs? Once a fictional idea, polymers now exist that are rugged enough to ferry packages or sensors into hostile territory and vaporize immediately upon a military mission's completion. The material has been made into a rigid-winged glider and a nylon-like parachute fabric. It could also be used someday in building materials or environmental sensors.

Lasers enable engineers to weld ceramics, no furnace required

Smartphones that don't scratch or shatter. Metal-free pacemakers. Electronics for space and other harsh environments. These could all be made possible thanks to a new ceramic welding technology. The process works in ambient conditions and uses less than 50 watts of laser power, making it more practical than current ceramic welding methods that require heating the parts in a furnace.

First microscopic look at a tiny phenomenon with big potential implications

Matter behaves differently when it's tiny. At the nanoscale, electric current cuts through mountains of particles, spinning them into vortexes that can be used intentionally in quantum computing. The particles arrange themselves into a topological map, but the lines blur as electrons merge into indistinguishable quasiparticles with shifting properties. The trick is learning how to control such changeable materials.

How electrons in transition metals get redistributed

Researchers have measured how electrons in so-called transition metals get redistributed within a fraction of an optical oscillation cycle. They observed the electrons getting concentrated around the metal atoms within less than a femtosecond. This regrouping might influence important macroscopic properties of these compounds, such as electrical conductivity, magnetization or optical characteristics. The work therefore suggests a route to controlling these properties on extremely fast time scales.
