Eduardwww [97]3 years ago

<u>ANSWER:</u>

Eratosthenes can be credited with being the 'first person' to calculate the 'circumference of the earth'.

<u>EXPLANATION:</u>

  • Eratosthenes measured the circumference of the earth by noting the 'angle of shadows' in two cities on 'summer solstice' and by performing calculations using his knowledge and geometry.
  • He lived in Alexandria which was in North Egypt.
  • He used Alexandria and Syene, a city in South Egypt for calculating the angle of shadow made on summer solstice because he knew that the 'sun was never overhead' in Alexandria even on summer solstice.
  • He measured the distance between the 'two cities' and applied geometry for calculating the 'circumference of the earth' in stadia which was a unit of measurement used at that time.

How does language contribute to ethnic conflict
Flauer [41]

Answer:

Conflict plays a role in many social sciences. Linguistically, conflict between different ethnic groups often results from language contact. Problems viewed as political, economic or sociological in nature are often actually rooted in linguistic conflict. In the literature, however, contact has overshadowed conflict. In addition, the emphasis in contact research has traditionally focussed on closed, homogeneous groups rather than on urban industrial societies in which social and linguistic conflict are important factors.

Language contact and conflict are seen as interdependently related elements applicable both to individuals and to language communities, yet these phenomena occur only between speakers of languages, not between languages per se.

This overview describes the characteristics of language conflict and looks at the areas of emphasis in the literature, including multilingualism and linguistic identity, glottophagia and minority/majority relations, the danger of reliance on language censuses, conflict resolution/avoidance, and the importance of ecolinguistics in conflict description and for research in the area of linguistic conflict.
