Question
Explain Cantor diagonal argument (table)?
**Cantor Diagonal Argument Table** The image contains a grid demonstrating Cantor's diagonal argument to illustrate the countability of rational numbers. ### Table Explanation: - The grid is an 8x8 table. - Each cell in the table contains a fraction, representing rational numbers. The fractions follow the format \( \frac{j}{i} \), where \( i \) is the row number and \( j \) is the column number. - The diagonal lines with arrows indicate a traversal pattern, suggesting a method to list all rational numbers systematically. - Circles around certain fractions denote repeated or simplified fractions as the traversal progresses. ### Summary: The image depicts the infinity pairing proof of Georg Cantor (1845-1918), illustrating how the infinite set of rational numbers is countable, possessing the same cardinality (size) as natural numbers (\( \{1, 2, 3, \ldots\} \)). The rational numbers can be counted similarly to natural numbers, including fractions derived from them. This table visually represents the concept that rational numbers, despite being infinite, can be systematically paired and counted like natural numbers.
