Artificial Intelligence: History, Capabilities, and Future
Intelligence is the ability to learn about, to learn from and understand and interact with one's environment. Artificial intelligence is the intelligence of machines and is a multidisciplinary field which involves psychology, cognitive science, and neuroscience and computer science. It enables machines to become capable of doing those things which the human mind can do. Though the folklore of artificial intelligence dates back to a long time ago, it actually became available to people only after the development of the electronic computer. Today research in artificial intelligence is so highly invested in and the field has significantly advanced to such an extent that it has become a huge part of our lives and it is considered to be America's Next big thing.
Metamorphic, Igneous, and Sedimentary Rocks Across the Solar System
There are reported to be three primary classes of rocks, which are classified according to their origination. The three rock types are metamorphic, igneous, and sedimentary rocks. Igneous rocks are formed when bodies of magma cool. As time passes and the rocks undergo process due to various weather cycles the igneous rocks erode and the particles and chemicals, which settle into beds, become compressed or cemented forming into what are known as sedimentary rocks. In the event igneous rocks are buried and then undergo a high state of heating and compression they form into what are known as metamorphic rocks. Eventually, the rocks undergo heat and compression and then melt with the molten rock forming another igneous rock in what is referred to as the rock cycle. Rocks may be turned from one type of rock into another rock. For example, it is reported that a sedimentary rock "such as sandstone can be weathered and eroded and those fragments might eventually end up as part of a shale, a different sedimentary rock."
