Welcome to Budapest, Hungary,

On behalf of the community of Hungarian scientists devoted to gravitational life sciences, I would like to welcome you to the 22^nd Annual Meeting of the International Society for Gravitational Physiology held in Budapest, the Capital of Hungary.

Hungarian people are proud of their scientists who have made major contributions in developing the space-era, both in technical fields, as J. von Neumann (1903-1957, the electronically stored digital program commands, game theory), E. Wigner (1902-1995, basic symmetry), Th. Kármán (1881-1963, jet propulsion), D. Gábor (1900-1979, holography), Z. Bay (1900-1992, first extraterrestrial experiment; radar echo from the Moon) and in the life sciences, like A. Szent-Györgyi (1893-1986, intermediate metabolism, molecular background of muscle contraction ), Gy. Békésy (1899-1972, biophysics of hearing), or J. Szentágothai (1912-1994, vestibulo-ocular reflex, neuronal network of cerebellum). The forthcoming meeting will reinforce our scientific and cultural cooperations with colleagues from around the globe.

The venue of the Meeting, the Hotel Hyatt Regency is in the heart of the City, facing Castle Hill (a UNESCO Treasure of the Word) across the river Danube. I hope that a bright cheerful spring will accompany you on your way to discovering the impressive sites and cultural events of our capital city.

Besides the planned Welcome Reception, Gala Dinner in the Márványmenyasszony (Marvel fiancée) Restaurant and the Congress Tour to Kecskemét and Bugac (Puszta), all the participants will have the opportunity to take part in other cultural programs on a voluntary basis.

We are looking forward to your visit and participation in the Meeting.

László Simon
President of ISGP
