  1. Educational history of Prof. Dr. Mezak Arnold Ratag

Prof. Dr. Mezak Arnold Ratag or familiarly called Mezak was born in Malang on September 24, 1962 as the third child of Prof. Alexander Ratag and Grietje Kawengian.

(Nebula Planeter di Alam Semesta yang bernama Nebula Heliks)

Mezak has presented and published more than one hundred national and international scientific papers. More than 100 new planetary nebulae (PNs) have been discovered and published with partners. In the catalogue of discoveries of the Planetary Nebula published by the Strasbourg Observatory, a large number of them are named after Mezak and the names of his partners. More than 100 international citations about his scientific works can be found in various international journals, books, and proceedings. A number of books have been written, namely Climate Change, Atmospheric Dynamics, Climate System Modeling, Aeronautical Meteorological Dictionary, Solar Activity and Earth's Climate Variations. In 1999, Mezak reaped the fruits of hard work by becoming a lecturer at the ITB Masters Program and Postgraduate Doctoral Program for Atmospheric Dynamics, Monsoon, Global Climatology, Climate Change, Climate, and Extreme Weather courses. Not only that, he also became a guest lecturer at a number of universities and institutes in the United States, Australia, Japan, the Netherlands, Italy, India, Thailand, Taiwan, and Malaysia.
