The box of Order and Chaos had a impressive growth within the final 50 years. the most cause was once using pcs, and the improvement of latest theoretical equipment that we name now 'the concept of chaos'. the writer describes this interesting interval in a calm and infrequently funny autobiographical method. He relates his interactions with many folks in dynamical astronomy and he charges numerous anecdotes from those interactions. He refers additionally to his stories while he served in numerous foreign positions, resembling common secretary of the IAU and chairman of the magazine Astronomy and Astrophysics. lately the idea of chaos has been prolonged to new parts, like relativity, cosmology and quantum mechanics and it keeps increasing in just about all branches of physics. The ebook describes many vital rules during this box in an easy means. It refers additionally to difficulties of extra normal curiosity, like writing papers and giving lectures and the interplay of authors and referees. eventually it offers a few worthwhile customers for the way forward for dynamical astronomy and comparable fields.

In the general case, stochastic instabilities can arise from intersection of narrow stochastic layers... , 65=Contopoulos). 44 ADVENTURES IN ORDER AND CHAOS Some people refer to a short earlier paper of Chirikov (1959). But this paper considers the successive crossings of various separate resonances by orbits, without mentioning resonance overlap. Later Chirikov did consider resonance overlap and in a letter to me, dated 23-10-68, he wrote: “My criterion of stochasticity by resonance overlapping is essentially the same as yours in your paper in Bulletin Astronomique (1967)”.

C. Lin, where he compared the energies due to the various fields acting on a galaxy, like magnetic fields, cosmic rays and gravitational fields. But this Table was biased in favour of the gravitational fields, because it 28 ADVENTURES IN ORDER AND CHAOS considered the whole gravitational energy, and not only the part due to the spiral arms. I was aware of this, and I wondered if I should present that slide at all. But as I started my talk I noticed that Chandra was soon asleep. Thus, I decided to show that Table, that was really spectacular.

But the Thessaloniki meeting was always remembered as the first meeting on dynamical astronomy. 11. IAU COMMISSION 33 After the IAU Symposium No 25 we had the IAU General Assembly in Hamburg (1964). There I had an unexpected and happy surprise. Bart Bok, who was then president of Commission 33 (Structure and Dynamics of the Galaxy), a successor of Oort and Blaauw, proposed me as vice-president of the Commission, implying that I should be his successor as president after three years. But his suggestion was objected by the Executive Committee.
