第一章 Universe and Substances：13.7 billion years ago, the blast of the singularity brought with it what we now know as universe, including celestial bodies and substances. Earth, one of the planets and home to humans, beholds their lives and breath.We will see magical etyma relating to celestial bodies, stars and earth, time, aviation, sea and waters, and stones.1.1Celestial Bodies:Universe or cosmos? Sun or moon or earth? You will learn etyma related to some of the most important celestial bodies human beings have ever discovered, some further relating to social traditions even.
1.2Stars and Earth:The solar system is where human being locate themselves in the spectacular universe. Theodore Roosevelt said:Keep your eyes on the stars, and your feet on the ground. This chapter will take you through etyma relating to stars and earth.
1.3Time:Time is an eternal theme that seems to be singular and relentless. However its word forming parts might take on a different look. Apart from the God of time, profound writers, kings and even Trump are all on its side.
1.4Time Flies:The old proverb goes 'time flies' -- the two words always seem to go hand in hand. In this chapter, we will explore etyma connecting to time and aviation. Let's travel in the scientific dimensions and feel the glamour of etyma.
1.5Sea and Waters:Water is probably the most common substance on earth, large in quantity but insufficient for need. Etyma for sea and waters again come in varied and with intersting combinations. You will have an expanded view about sea and waters here.
1.6Stones:Stones leave the impression of stuborness and hardness. Etyma relating to it, of course, contain the same meaning but can be more imaginative sometimes. You will learn about the stones in plants, fruits and even human bodies. And all different kinds of shiny. precious and gorgeous gems of course.
