AbstractSawai Jai Singh, the statesman astronomer of 18th century India, designed instruments, built observatories, prepared Zīj, and sent a fact-finding scientific mission to Europe. His high-precision instruments were designed to measure time and angles with accuracies of ± 2 second, and ±1’ of arc respectively. The Ṣaṣṭhāmsa, a meridian dial with aperture, can still measure angles with precision of ± 1’ of arc. In the age of Newton and Flamsteed, Jai Singh and his associates remained medieval, in the tradition of Ulugh Beg, and did not initiate the new age of astronomy in the country. A complex interaction of poor communications, religious taboos, theological beliefs, national rivalries and plain simple human shortcomings are to be blamed for the failing.

The first part of the article is dedicated to a historical review of the foundation of Brazil’s present Capital - from the very first intentions of the 18th century colonial times when the foundation of a new Capital was seen as part of a movement towards national independence, up to the optimistic 1950s when the project became a fundamental element in a ‘new age’ of social progress and economic prosperity. At the same time, Brasflia was offered as an utopian playground for modem urbanistic and architectural thoughts, formulated by Liicio Costa and Oscar Niemeyer with inspiration from international functionalist trends. The realization of Brasflia contained both the motivation to accelerate national development aiming at integration into the industrial world, and the intention that this new city could humanize an unjust economic system. The second part of the article discusses the urbanistic project and its inherent symbolic and utopian motives, as well as the experiences of the present inhabitants, evaluating the expectations of Brasflia thirty years after.

The article is devoted to the development and formation of the Italian vocal schools in the era of the New Age. The most important aspects of the development of the Italian vocal school are the domination of castrate singers in the 18th century and their gradual ousting in the era of the romantic opera formation. During the 20th century, the internationalization of Italian opera and vocal teaching methods take place. The study is based on a complex of historical methods. The materials are of interest to researchers of vocal technology and cultural history.

Concrete was used for construction in many ancient structures. Concrete technology was known by the Ancient Romans and was widely used within the Roman Empire. After the Empire passed, use of concrete became scarce until the technology was re-pioneered in the mid-18th century. The widespread use of concrete in many Roman structures has ensured that many survive to the present day. The development of reinforced concrete marked the dawn of a new age. For it was the first heterogeneous building material, using steel, cement, sand, gravel, and water. This composition possessed much better properties than each of its individual components.

Contemporary fiscal theorizing largely assimilates the activities of government to that of some choosing agent. This paper explores an alternative approach where government is assimilated to an emergent process of complex interaction, as a form of complex adaptive system. Within this alternative vision, governments are treated not as objects of intervention into a market economy but as arenas of organized participation within it. While recent developments in computational modeling are starting to provide tools for probing such a vision, the roots of that vision can be traced back to the spontaneous order theorists of the 18th century. After sketching some contours of this alternative vision, the remainder of the paper explores some possible implications of this change in vision for mapping the relationship among taxation, prosperity, and justice.

In English Literature a significant change took place in 1798 originated by William Wordsworth and Samuel Taylor Coleridge who in Lyrical Ballads broke with the reigning school of Pope and the spirit of the 18th century to achieve a new art freer in form and suited to the spirit of their time: Coleridge with poems of romantic wonder, Wordsworth with poems of nature and simple humanity. The new poetic tradition established by them and later romantic poets remained in authority in America until 1855 when the revolt of Walt Whitman, breaking away from the past, proclaimed a new age for America's poetry. Whitman considered himself - and was to some extent for his time - a literary radical, and as such he did not hesitate to write essays, poems, or utter remarks which among other things anathematized the poetry of his day.
