Chemistry

Chemistry is the science of matter at the atomic to molecular scale, production mainly with collections of atoms, such as gases, molecules, crystals, and metals. Chemistry deals with the composition and statistical properties of such structures, as well as their transformations and interactions to become materials encountered in daily life. Chemistry also deals with sympathetic the properties and interactions of individual atoms with the purpose of applying that knowledge at the macroscopic level. According to contemporary chemistry, the physical properties of materials are usually determined by their structure at the atomic scale, which is itself defined by interatomic forces.

Marble

Marble is a metamorphic rock resulting from the metamorphism of limestone, collected from calcite (a crystalline form of calcium carbonate, CaCO3). It is broadly used for sculpture, as a building material, and in several other applications.

A Brief History of the Internet

By default, any ultimate history of the Internet must be short, since the Internet in one form or another has only been in reality for less than 30 years. The first iteration of the Internet was launched in 1971 with a community showing in early on 1972. This new network, recognized as ARPANET. It means Advanced Research Projects Agency Network was very ancient by today's standards, but an objective in computer interactions.
ARPANET was based upon the design concepts of Larry Roberts (MIT) and was fleshed out at the first ACM colloquium, held in Gaithersburg, TN in 1966, although RFPs weren't sent out until mid 1968.
The responsibility of security in 1969 commissioned ARPANET, and the first node was created at the University of California in Los Angeles, administration on a Honeywell DDP-516 mini-computer. The second node was recognized at Standford University and launched on October first of the same year. The third node was situated at the University of California, Santa Barbara November 1, 1969 and the fourth was opened at the University of Utah in December.
