Tor (rock formation)

A tor, which is also known by geomorphologists as either a castle koppie or kopje, is a large, free-standing rock outcrop that rises abruptly from the surrounding smooth and gentle slopes of a rounded hill summit or ridge crest. In the South West of England, the term is commonly also used for the hills themselves – particularly the high points of Dartmoor in Devon and Bodmin Moor in Cornwall.

Name

The word tor (Cornish: tor, Old Welsh: twrr, Welsh: tŵr, Scottish Gaelic: tòrr), meaning hill, is notable for being one of the very few Celtic loanwords to be borrowed into vernacular English before the modern era – such borrowings are mainly words of a geographic or topographical nature. Another such word is crag (from Welsh craig "rock").

Formation

Tors are most common and most well known as a landform that was created by the erosion and weathering of granitic rocks. However, tors have also developed by the erosion and weathering of schists, dacites, dolerites, and coarse sandstones among other rock types. Tors are mostly less than 5 meters (16 ft) high. A variety of hypotheses have been proposed to explain the origin of tors and their origin remains a topic of continuing discussion among geologists and geomorphologists, and physical geographers. It is considered likely that tors were created by geomorphic processes that differed widely in type and duration according to regional and local differences in climate and rock types.

.tor

.tor is a pseudo-top-level domain host suffix implemented by the OnioNS project, which aims to add DNS infrastructure to the Tor network enabling the selection of meaningful and globally-unique domain name for hidden services, which users can then reference from the Tor Browser.

The project aims to address the major usability issue that has been with Tor hidden services since their introduction in 2002.

Beta release of the server, client and domain name reservation tool (so called hidden service) software parts and their supporting common library were announced in the Tor developers mailing list in August 2015.

According to the description on the projects gitsite "OnioNS is a distributed, privacy-enhanced, metadata-free, and highly usable DNS for Tor hidden services"

The system is powered by the Tor network, relies on a distributed database, and provides anonymity to both operators and users.

Eratosthenes

Eratosthenes of Cyrene (/ɛrəˈtɒsθəniːz/; Greek: Ἐρατοσθένης, IPA: [eratostʰénɛːs]; c. 276 BC – c. 195/194 BC) was a Greek mathematician, geographer, poet, astronomer, and music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. He invented the discipline of geography, including the terminology used today.

He is best known for being the first person to calculate the circumference of the Earth, which he did by applying a measuring system using stadia, which was a standard unit of measure during that time period. His calculation was remarkably accurate. He was also the first to calculate the tilt of the Earth's axis (again with remarkable accuracy). Additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. He created the first map of the world incorporating parallels and meridians, based on the available geographical knowledge of the era.

Eratosthenes was the founder of scientific chronology; he endeavored to revise the dates of the chief literary and political events from the conquest of Troy. In number theory, he introduced the sieve of Eratosthenes, an efficient method of identifying prime numbers.
