Computer assisted performance tests of the Lyman Alpha Coronagraph

Preflight calibration and performance tests of the Lyman Alpha Coronagraph rocket instrument in the laboratory, with the experiment in its flight configuration and illumination levels near those expected during flight were successfully carried out using a pulse code modulation telemetry system simulator interfaced in real time to a PDP 11/10 computer system. Post acquisition data reduction programs developed and implemented on the same computer system aided in the interpretation of test and calibration data

Lyman alpha coronagraph research sounding rocket program

The ultraviolet light coronagraph was developed and successfully flown on three rocket flights on 13 April 1979, 16 February 1980 and 20 July 1982. During each of these flights, the Ultraviolet Light Coronagraph was flown jointly with the White Light Coronagraph provided by the High Altitude Observatory. Ultraviolet diagnostic techniques and instrumentation for determining the basic plasma parameters of solar wind acceleration regions in the extended corona were developed and verified and the understanding of the physics of the corona through the performance, analysis and interpretation of solar observations advanced. Valuable UV diagnostics can be performed in the absence of a natural solar eclipse

The Moments of the Hydrogen Atom by the Method of Brackets

Expectation values of powers of the radial coordinate in arbitrary hydrogen states are given, in the quantum case, by an integral involving the associated Laguerre function. The method of brackets is used to evaluate the integral in closed-form and to produce an expression for this average value as a finite sum

A (too) brief explanation of the terms "Bildung" and "Erziehung" for the hurried English-speaking reader

The German terms “Bildung” and “Erziehung” are hardly translatable and are therefore occasionally used internationally as loanwords. This text attempts to explain their meanings in a brief manner to an international readership. In doing so, a distinction is made between formal definitions and supplementary connotative meanings. Furthermore, broad and narrow sense definitions are being compared. (DIPF/Orig.)Die schwer übersetzbaren deutschen Ausdrücke “Bildung” und “Erziehung” finden bisweilen auch international Verwendung. Es wird der Versuch unternommen, die Bedeutungen dieser Termini in knapper Form einer internationalen Leserschaft nahezubringen. Dabei werden sowohl formale Definitionen von konnotativen Bedeutungszusätzen unterschieden als auch Begriffsbestimmungen im weiten und im engen Sinn. (DIPF/Orig.

Review of Tranquebar―Whose History? Transnational Cultural Heritage in a Former Danish Trading Colony in South India, by Helle Jørgensen, New Delhi, Orient BlackSwan, 2014, xi + 356pp., $40/£42, Hardcover, ISBN 9788125053453

Jørgensen examines the emergence of Tranquebar as a heritage town in post-colonial India through the diverse, sometimes competing interests and claims of local residents, state-oriented institutions, scholars and policy makers, non-governmental organisations, and private entrepreneurs. Tharangambadi, Nagapattinam, Tamil Nadu, colloquially known as Tranquebar, is a fishing community of about 23000 people on the Coromandel Coast of India. Tranquebar was one of two trading posts that the Danish East India Company established in the 1600s, and that were taken over by the Danish Crown in 1650. The British East India Company acquired Denmark‟s Indian territories in 1845, and they were subsequently taken over in 1857 by the British Crown when the Company was dissolved. These territories were transferred to the Indian national government in 1947, when India gained independence from the British Crown. Jørgensen investigates the use of the past, that is, the making of Tranquebar into a destination for heritage tourism based on its Danish colonial history. The study takes place in the aftermath of the Indian Ocean earthquake on December 26, 2004. This major seismic event centred in the west coast of Sumatra, resulted in a powerful tsunami that radiated from there toward each country that shares a coastline on the Indian Ocean. The tsunami inundation in turn, caused the destruction of infrastructure, towns and villages, the displacement of coastal communities and the loss of human life. Tranquebar was severely impacted and since the tsunami, initiatives to promote economic growth in the town have intensified
