6. Fascinating Fact
This fact is significant because it highlights the vastness and complexity of the number system. The set of rational numbers is countable, meaning that it can be put into one-to-one correspondence with the set of natural numbers. However, the set of irrational numbers is uncountable, meaning that it cannot be put into one-to-one correspondence with the set of natural numbers. This means that there are infinitely more irrational numbers than rational numbers.
The set of irrational numbers from 1 to 100 is a subset of the set of irrational numbers. This subset is also uncountable, meaning that there are infinitely more irrational numbers between 1 and 100 than there are rational numbers between 1 and 100.
This fact has important implications for our understanding of the world around us. For example, it means that there are an infinite number of points in a line segment, an infinite number of points on a circle, and an infinite number of points in a sphere. This vastness and complexity is reflected in the many different phenomena that we observe in the world around us.
The fact that the set of irrational numbers is much larger than the set of rational numbers is a fundamental property of the number system. It is a property that has important implications for our understanding of the world around us.
