1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [ 5] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
Göbekli Tepe ( Turkish: [ɟœbecˈli teˈpe], [ 2] 'Potbelly Hill'; [ 3] Kurdish: Girê Mirazan or Xerabreşkê, 'Wish Hill' [ 4]) is a Neolithic archaeological site in the Southeastern Anatolia Region of Turkey. The settlement was inhabited from around 9500 BCE to at least 8000 BCE, [ 5] during the Pre-Pottery Neolithic.
Glass is an amorphous ( non-crystalline) solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass like "a glass" of water, "glasses", and "magnifying glass", are named after the material. Glass is ...
Ceratanium (ceramic titanium) is shown to be quite useful. It is sturdy yet lightweight; and Magnet Man in the comic series, says it is paramagnetic. It is thus used in multiple robots, being the key component in Mega Man'sarmor, the Metal Blades of Metal Man, Cut Man's Rolling Cutter, and Hard Man's body. Chelonium.
The universe is all of space and time [ a] and their contents. [ 10] It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of energy and matter, and the structures they form, from sub-atomic particles to entire galactic filaments. Space and time, according to the prevailing ...
The neutron is a subatomic particle, symbol n or n0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, they are both referred to as nucleons.
Schrödinger's cat. Schrödinger's cat: a cat, a flask of poison, and a radioactive source connected to a Geiger counter are placed in a sealed box. As illustrated, the quantum description uses a superposition of an alive cat and one that has died. In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition.
