Chapter 1. (L1)-Introduction

• Basic Theme of Chemistry
• A basic theme is emerging
• We can use some basic elements to compose
  various things, such as in the cases of money,
  music (keyboard), and language.
• Chemistry is a language.

32
Chapter 1. (L1)-Introduction

• Basic Theme of Chemistry
• For a language, we can ask these questions
• What are the basic letters of English?
• How do the letters become the language of
  English? (letter, words, sentences, paragraph,
  and so on)
• What is the grammar (rules and laws)?

33
Chapter 1. (L1)-Introduction

• Basic Theme of Chemistry
• Likewise, we can ask the similar questions about
  matter
• What are the basic elements for matter?
• How can we determine what these basic elements
  are?
• How small are they?
• How do these elements make various things?
• How can we use these elements to explain and
  describe the changes of things?

34
Chapter 1. (L1)-Introduction

• Basic Theme of Chemistry
• Chemistry is the science to answer these
  questions.
• The answers are not arbitrary, but have to be
  given in a scientific way.

35
Chapter 1. (L1)-Introduction

• Basic Theme of Chemistry
• In this course, we will learn how chemistry
  answers these questions, and explains the
  different things and their changes around us.
• And, also, we will learn the scientific way to
  answer these questions.
• In other words, we will learn the language of
  chemistry as science.
