It has always seemed to me that the many parts that make up the subject of biology are related to each other more like the nodes of a web than as a linear collection of independent topics. So I believe that the power of hypertext will be better suited to learning about biology than is the linear structure of a printed textbook. Another disadvantage of printed textbooks is the inevitable delay between the time that new advances in biology are reported and the time that they can become incorporated in a printed book (often several years). Material here can be updated promptly. So although some of this information has been drawn from the sixth edition of the author's text Biology published in 1994 by Wm. C. Brown, every effort has been made to adapt the material to the opportunities provided by an online text.

Why Should Americans Study World Politics?

1. It can kill you.
2. It costs you money.
3. It affects your job.
4. It affects your shopping.
5. It affects your health.
6. The world is becoming more and more globalized, more and more quickly.

Whether we like it or not, world politics affects us greatly. So it is a good idea for us to know what is going on out there.

Chemistry is all around us "from the air we breathe to the food we eat" to the items at the supermarket that say “no chemicals added”. In fact, it is impossible to create something without using chemistry because chemistry consists of all matter. It allows us to answer questions as simple as why a candle goes out when a glass is placed over it to more complex questions such as does a candle actually burn in zero gravity? Chemistry is the study of matter and the changes it undergoes such as ice changing from the solid to liquid to gas phase. People have used it for things such as creating metal from an ore, dying fabric and making cheese. Chemistry deals with different substances and how they can interact with each other to create a product.

As you begin your study of college chemistry, those of you who do not intend to become professional chemists may well wonder why you need to study chemistry. You will soon discover that a basic understanding of chemistry is useful in a wide range of disciplines and career paths. You will also discover that an understanding of chemistry helps you make informed decisions about many issues that affect you, your community, and your world. A major goal of this text is to demonstrate the importance of chemistry in your daily life and in our collective understanding of both the physical world we occupy and the biological realm of which we are apart.

People around the world are fascinated about the preparation of food for eating.
