In other times, the astrolabe guided sailors on their journeys and revealed to people the movements of the stars and their bright flashes. The modern astrolabe, held in the reader's hands, has no different ambition. However, the journey it promises hides greater surprises and unexpected paths. It will start from the wonders of the Universe, distant galaxies and comets, antimatter and the brilliant explosions of stars. Then, it will seek the answers that today's science provides to humanity's age-old questions: about the concept of time and the existence of extraterrestrial life, about the great CERN experiment and the detection of the ghostly neutrino in the depths of the sea in Pylos.

However, its journey with the reader will also allow the astrolabe a different tour. That of the world of man and his Life. First, it will try to trace the painful crisis that currently holds Greece captive; and to identify, in its recent course, the causes of today's woes, as well as its achievements. The tour will be completed - with the reader's companionship, always - with a look at modern man and his fate; who feels suspended between the explosive growth of technology and the dominance of an economic system with a callous face.

So, the journey promised by today's Astrolabe has a familiar destination. It is the worlds that the author has been moving in for years: the enigmas of the Universe and the course of Greece, the conquests of science and human fate. Only now, these worlds of the author, like the Universe itself after the Big Bang, seem to be suddenly and inexplicably expanding, as if they want to cover space and time. Their expectation is that somewhere there they will meet the worlds of the reader, his anxieties and questions. Then the handshake, between the author and the reader, will no longer be in the dark. It will take place under the light of the stars and with the mark revealed by an astrolabe of the Sky and Life.
