Heinrich Gustav Magnus - Research

Research

Magnus published 84 papers in research journals. His research output was continuous over his lifetime: the first memoir was published in 1825 when he was still a student, and the last appeared shortly after his death in 1870. From 1825 to 1833 he was occupied mainly with chemical researches. These resulted in the discovery of the first of the platino-ammonium class of compounds (see Magnus's green salt). He was first to identify the three sulfonic acids sulphovinic acid, ethionic acid and isethionic acid and their salts; and, in cooperation with CF Ammermüller, of per-iodic acid and its salts. He also reported on the diminution in density produced in garnet and vesuvianite by melting (1831). Subjects on which he published research after 1833 include: the absorption of gases in blood (1837–1845); the expansion of gases by heat (1841–1844); the vapour pressures of water and various solutions (1844–1854); thermoelectricity (1851); electrolysis of metallic salts in solution (1857); electromagnetic induction of currents (1858–1861); absorption and conduction of heat in gases (1860s); polarization of heat (1866–1868); and the deflection of projectiles from firearms (see Magnus effect). From 1861 onwards he devoted much attention to the question of diathermancy in gases and vapours, especially to the behaviour in this respect of dry and moist air, and to the thermal effects produced by the condensation of moisture on solid surfaces. Magnus was an experimenter, not a theoretician.

Famous quotes containing the word research:

    ... research is never completed ... Around the corner lurks another possibility of interview, another book to read, a courthouse to explore, a document to verify.
    Catherine Drinker Bowen (1897–1973)

    The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of “justice” or absolute “right and wrong,” while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?
    Ron Taffel (20th century)

    Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.
    Bettina Arndt (20th century)
