Κοσμικό Φως: Αρχέγονο και Ανέσπερο

Το Κέντρο Ερευνών Αστρονομίας και Εφηρμοσμένων Μαθηματικών της Ακαδημίας Αθηνών (ΚΕΑΕΜ) οργάνωσε μια σειρά εκλαϊκευτικών ομιλιών στο πλαίσιο του Διεθνούς Έτους Φωτός 2015.

Το 2015 έχει ανακηρυχθεί από την UNESCO ως «Διεθνές Έτος Φωτός και Τεχνολογιών με βάση το Φως». Στόχος του Διεθνούς Έτους είναι να αναδείξει, σε παγκόσμιο επίπεδο, τον τρόπο με τον οποίο το φως και οι βασισμένες σε αυτό τεχνολογίες επηρεάζουν κάθε πτυχή της ανθρώπινης ζωής. Οι εννέα (9) ομιλίες δόθηκαν από τους ερευνητές και τους συνεργάτες του ΚΕΑΕΜ και αφορούσαν το φως όπως αυτό γίνεται αντιληπτό από τις Θετικές Επιστήμες. Γι αυτόν το λόγο ο κύκλος των ομιλιών είχε τον γενικό τίτλο “Κοσμικό Φως – Αρχέγονο και Ανέσπερο” και είχε ως στόχο να παρουσιάσει τον τρόπο που οι πληροφορίες που μεταφέρει το φως επηρεάζουν την αντίληψη που έχει ο άνθρωπος για το Σύμπαν.

Οι διαλέξεις δόθηκαν σε δύο περιόδους (Μάιο – Ιούνιο και Σεπτέμβριο – Οκτώβριο) στο κεντρικό κτήριο της Ακαδημίας Αθηνών (Ανατολική Αίθουσα) κάθε δεύτερη Τετάρτη στις 7μ.μ.

Chaos in Astronomy

Chaos in Astronomy, G. Contopoulos and P.A. Patsis (eds)., 2009, Springer, ISBN 978-3-540-75825-9

The conference "Chaos in Astronomy" was held in Athens on 17-20 Sep 2007. International leaders in the field addressed the topics

  • Chaos in large N-body systems and in galactic dynamics
  • Chaos in solar system dynamics
  • Statistical mechanics of systems with regular and chaotic orbits
  • Chaos in the formation of large-scale structure in the Universe
  • Fundamental concepts, methods and tools.

The book contains carefully edited refereed contributions. It serves as a reference to researchers and gives an overview to students and newcomers entering any field of dynamical astronomy.

Order and Chaos in Galactic Astronomy

George Contopoulos

Order and Chaos in Dynamical Astronomy, 2002, Springer, ISBN: 3-540-43360-0.

The book was published in Summer 2002. In its 618 pages the book contains an overview of the knowledge developed during the last 50 years in Chaotic Dynamics and Dynamical Astronomy. It contains also a list of about 70 unsolved yet problems. This is a reference book for many researchers in Astronomy and related fields. Its first edition was exhausted and its second edition appeared in 2004.

Galaxies and Chaos

Galaxies and Chaos, G. Contopoulos and N. Voglis (eds)., LNP (Lecture Notes in Physics), vol. 626, 3, Springer Verlag

This volume contains selected articles from the proceedings of the International Workshop on “Galaxies and Chaos. Theory and Obeservations” held in Athens, 16-19 September 2002. The book deals with the most recent results concerning the role of chaos in the formation, stability and morphology of gravitational systems in scales ranging from planetary to galactic.

Adventures in Order and Chaos

George Contopoulos

Adventures in Order and Chaos: A Scientific Autobiography
Astrophysics and Space Science Library, Vol. 313, 2005, X, 199 p., Hardcover, ISBN: 1-4020-3039-8, Springer Verlag / Kluwer

The book describes the experiences of the author after fifty years of research in the field of order and chaos in astronomical dynamical systems. It exposes a number of important notions related to the theory of order and chaos in a simple and informal way. It also includes subjects of more general scientific interest, such as advices for paper writing, lecturing and refereeing. Finally, the book gives a useful assessment of future perspectives of dynamical astronomy.
