22 May: 150 Years of Elemental World Order

Series of lectures on the UNESCO Year of the Periodic System of Elements for pupils, teachers and students.

Wann: Mittwoch, 22. Mai 2019, von 16.00 bis 18.00 Uhr Für interessierte Schüler*innen ab der 8. Schulstufe sowie Lehrer*innen und Studierende Freier Eintritt zur Veranstaltung

Im Jahr 1869 ordnete der Chemiker D. I. Mendelejew die chemischen Elemente nach ihren Eigenschaften und ihrem spezifischen Gewicht in eine Tafel: Das Periodensystem der Elemente war geboren. Zu diesem Anlass erklärte die UNESCO das Jahr 2019 zum „Jahr des Periodischen Systems der Elemente“ und lud die wissenschaftliche Gemeinschaft ein, die Bedeutung dieses Systems in der Öffentlichkeit zu diskutieren. Der wissenschaftliche Fortschritt führte zu einer vollständigen Erklärung des Systems und damit zu einem gemeinsamen Verständnis aller physikalischen, chemischen und biologischen Phänomene. Auch die Entstehung der Elemente in der kosmischen Entwicklung der Sterne ist weitgehend verstanden. Darüber hinaus führte dieses Wissen zu einer beeindruckend breiten Anwendung in Technik und Medizin. Zu diesem Jubiläum laden wir zu einer Vortragsreihe ins Haus der Natur. Fachleute erläutern die Bedeutung der chemischen Elemente als Bausteine der uns bekannten Welt und ihre fundamentale Rolle in Physik, Chemie, Biologie und Astronomie.
