Creeper was an experimental computer program written by Bob Thomas at BBN in 1971. [2] Its original iteration was designed to move between DEC PDP-10 mainframe computers running the TENEX operating system using the ARPANET , with a later version by Ray Tomlinson designed to copy itself between computers rather than simply move.

This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
In physical geography, a dell is a grassy hollow—or dried stream bed—often partially covered in trees. [1] [2] In literature, dells have pastoral connotations, frequently imagined as secluded and pleasant safe havens.

The term was criticized by James M. Blaut: "the word metageography seems to have been coined by the authors as an impressive-sounding synonym for 'world cultural geography.'" [4] Lewis and Wigen, however, disagreed, arguing that every consideration of human affairs employs a metageography as a structuring force on one's conception of the world [5]
Isoamplitudes are drawn on maps of amplitudes (for example, annual amplitudes of air temperature—that is, the differences between the mean temperatures of the warmest and coldest month). Isanomals are drawn on maps of anomalies (for example, deviations of the mean temperature of each place from the mean temperature of the entire latitudinal ...
