Unbestreitbar ist die Mathematik eine der ältesten Wissenschaften. Aber warum eigentlich? Hatten unsere fernen Vorfahren nichts Dringenderes zu tun als die Ent­ wicklung von Gedankenakrobatik? Waren nicht erst einmal elementare l..ebensbedürfnisse zu befriedigen: Nahrung, Wohnung, Organisation des Zusammenlebens? Gewiß. Aber genau deshalb entstand die Mathematik. Sie war für die Menschen wichtig bereits zu einer Zeit, aus der es keine aufgeschriebene Geschichte gibt. Aus späteren Jahrtausenden wissen wir dann genauer, daß Feldvermessun­ gen nach dem jährlichen Nilhochwasser die Geometrie voranbrachten, daß die Entwicklung von Geschützen die Berechnung von Bahnkurven nach sich zog und daß die Konstruktion moderner Flugzeuge mit Fortschritten der Strömungslehre verknüpft war. Die Mathematik ist heute eine vollent­ wickelte Wissenschaft, weil sie in wesentlichen Teilen die Praxis überholt hat, denkrnögliche Strukturen untersucht und wissenschaftlichen Vorlauf schafft. Gleichzeitig entwickelt sie sich als Bestandteil der allgemeinen Kultur. Diese hochabstrahierende und zuweilen verspielt anmutende Mathematik wird nun nicht selten als praxisabgewandt angesehen. Auf die Frage, womit sich die Mehrzahl der Mathematiker gegenwärtig beschäftigt, können selbst Freunde dieser Wissenschaft oft keine befriedigenden Antworten geben. Daß Mathematiker heute an Computern sitzen, wäre eine zu oberflächliche Feststellung, denn der Computer ist zwar ein wesentliches Werkzeug, nicht aber der Inhalt der Arbeit. Außerdem gehört er inzwischen zu sehr vielen Berufen.

The Gmelin Formula Index and its First Supplement covered those volumes of the Eighth Edition of the Gmelin Handbook which had been issued up to the end of 1979. The present Second Supplement updates the Index by inclusion of the volumes which appeared until the end of 1987. With this Second Supplement all compounds described in the Gmelin Handbook of Inorganic Chemistry in the period between 1922 and 1987 can be located. The basic structure of the Formula Index remained the same as in the previous editions. Computer techniques were employed in the preparation and print of the Second Supple­ ment. The data acquisition, sorting and further data handling were performed with the aid of a suite of computer programs developed by staff members of the former" Online Group" of the Gmelin Institute, now at Chemplex GmbH, and the printer, "Universitätsdruckerei H. Stürtz AG, Würzburg ". The present Second Supplement is intended to be the last one which is issued in printed form. The cumulated contents of the Index and its Supplements are contained in the Gmelin Formula Index (GFI) database wh ich is available to the scientific community via STN. This database will be updated annually to reflect the published Handbook volumes as close as possible.

The present Second SuppLement updates the Index by incLusion of the voLumes which appeared up to the end of 1987. With this Second SuppLement aLL compounds described in the GmeLin Handbook of Inorganic Chemistry in the period between 1924 and 1987 can be Located. The basic structure of the FormuLa Index remains the same as in the previous editions. Computer techniques were empLoyed in the preparation and print of the Second SuppLe- ment.
