This will be a journey into the universe. It will be a journey for everyone: no prior knowledge of Physics is required, and the mathematical concepts we will use will be familiar to any traveler who has completed first year of high school.
It will be a journey of search: what will interest us most is not the answers themselves, but how we arrive at those answers. How do we know what we know about the universe? And how will we discover what we do not yet know? Our first attitude it will be our cosmic neighborhood, the Solar System.
Our purpose will be to know our home, the Earth, as part of our own corner of the universe. We will talk about heaven as we see it from planet Earth. For the brightest bodies in the sky, the Sun and the Moon. For the fascinating story of the discovery of the laws of nature that govern the motions of celestial bodies, which is at the same time the story of the beginning of the science of Physics.
For the friendly star of our neighborhood, the Sun, who provides us with all energy which sustains life on Earth and our civilization by burning itself with thermonuclear reactions. For the planets, others worlds so different from Earth, and so different from each other. For the big one εξερεύνηση, the journey of mankind's machines to the ends of the solar system, and beyond.
Have a good trip.
