I was with the Department of Radio Astronomy of the TCfA (DRA; until 1996 Torun Radio Astronomy Observatory) since 1972, i.e. when I have finished studying at the Nicolaus Copernicus University till retirement in 2015. As a scientific worker for some 8 years I have been responsible for carrying out the solar observations at 127 MHz and their analysis (this eventually led to my Ph.D. in 1980). Then I engaged myself in the VLBI (Very Long Baseline Interferometry) methods and techniques, especially in applications of VLBI to astrometry and geodesy. Among my other scientific interests were: astronomical time and calendars (see e.g. a sundial design, procedures for conversion of the Gregorian, Julian, Persian/Jalaali calendars and Julian Day Number, and Easter dating), ephemerides of the solar system bodies (Sun, Moon and planets; see e.g. my calculations of beginnings of seasons, zodiacal signs and of phases of the Moon – till 2025 to 2100), solar and lunar eclipses and certain aspects of radio astronomical instruments: receivers and telescopes (see e.g. some analyses related to our existing 32 m telescope and an offset paraboloid idea, OptiCass – a new software for developers of Cassegrain telescopes, and an analysis of BBC properties). Of about a hundred of my publications (thematically arranged here) really only one seems to have aroused worldwide interest and firm acceptance: "Accurate Algorithms to Transform Geocentric to Geodetic Coordinates". After Warsaw authorities refused to approve my thesis for a higher scientific degree (defended in 1994), since 1996 I took a position devoted mainly to technical duties. An interesting scientific endeavour I soon afterwards got involved into is a search for gravitational wave signals – first ever attempt of this kind.

Privately, born in 1948, in 1981 I was married to Zsuzsanna Vizi (we parted in 2001) and we have three children aged now (2015) 27 to 33. My hobby are wonderful teachings of Sri Sathya Sai Baba, a great contemporary Saint of South India believed by many to be the Avatar, i.e. Godhead descended on Earth (for more information on Him see these links). If you are eager to know how He answers some fundamental questions have just a quick look at this sample (for Polish readers I propose a variety of translations of the Swami's teachings).
