<h1>What is the World made of?</h1>
|
|
|
|
<p>The world around us, everything we see, touch, smell and taste, is
|
|
made of matter. Everything from the device you are reading this
|
|
webpage on and the ground that you are standing on to your body and
|
|
the air you breathe - all consist of matter. But what is "matter"?
|
|
People have been puzzling over this question for generations. In the
|
|
early 20th century, it was believed that the smallest unit of matter
|
|
was the atom (from greek atomos, meaning indivisible). It was known
|
|
that atoms of different types have different properties and cannot be
|
|
transformed into one another. However, today we know what atoms are
|
|
made up of and why the different atoms have different properties. </p>
