The box of Order and Chaos had a extraordinary enlargement within the final 50 years. the most cause used to be using pcs, and the improvement of recent theoretical tools that we name now 'the thought of chaos'. the writer describes this attention-grabbing interval in a calm and infrequently funny autobiographical approach. He relates his interactions with many of us in dynamical astronomy and he fees numerous anecdotes from those interactions. He refers additionally to his stories whilst he served in a variety of overseas positions, similar to basic secretary of the IAU and chairman of the magazine Astronomy and Astrophysics. lately the speculation of chaos has been prolonged to new components, like relativity, cosmology and quantum mechanics and it maintains increasing in just about all branches of physics. The booklet describes many very important rules during this box in an easy means. It refers additionally to difficulties of extra basic curiosity, like writing papers and giving lectures and the interplay of authors and referees. eventually it provides a few worthy customers for the way forward for dynamical astronomy and comparable fields.

Therefore one has to be careful in applying the third integral in every case. 5 Solitons Certain partial differential equations (PDEs) have some remarkable solutions that represent isolated waves called solitons. Such equations are the Kortewegde Vries (KdV) equation, the sine-Gordon equation, the nonlinear Schr¨odinger equation, etc. These are called “integrable PDEs”. The solitons move indefinitely unchanged, until they are reflected. When two solitons collide they interact in a very complicated way, but later on they reappear unchanged as they move away from each other.

In Prague I organized a meeting of Commission 33 on the “theoretical approaches to spiral structure”. This contained papers by C. C. Lin on “the density wave theory”, and by S. B. Pikelner on “magnetic approaches to spiral structure”. I presented also a gas dynamical version of the density wave theory that was developed by M. Fujimoto in Columbia University. I was familiar with this work since I had been in Columbia several times and had many discussions with Fujimoto and Prendergast. (The work of M.

One friend was Dr. Angelo Skalafuris who was working next to my office at the Institute of Space Studies. He helped me several times with his car. On one occasion I asked him if he could take me from the airport when I should return from a trip next Sunday. “At what time are you coming”? he asked. “About 5 o’clock” I said. He looked embarrassed. “I am sorry but I cannot come” he said “because at that time I am getting married”. I offered him my best wishes and I added: “How is it possible to say that you are sorry, if you are getting married”?
