Alabama Paradox: 동영상 및 연습문제
The provided content does not cover the Alabama Paradox. Instead, it explains fractal geometry, where a starting figure is changed by the same rule again and again through recursion. A fractal is built by repeatedly applying this rule infinitely many times, creating a pattern with detailed structure at smaller and smaller scales.
A central property of fractals is self-similarity, meaning smaller parts of the figure resemble the whole figure. The main example discussed is the Sierpinski triangle, formed by repeatedly removing the center triangle from each equilateral triangle that appears. As this process continues, the figure becomes visually stable, meaning later changes become too small to notice even though the rule is still being applied.

The Alabama Paradox is a counterintuitive phenomenon in apportionment methods, particularly in the context of distributing seats in a legislature based on population. It occurs when increasing the total number of seats results in a state receiving fewer seats than before. This paradox highlights a flaw in some apportionment methods, such as Hamilton's method, where adding more seats can paradoxically reduce a state's allocation. Understanding the Alabama Paradox is important for students studying political science, mathematics, or economics because it illustrates challenges in fair representation and the complexities of proportional allocation.
The Alabama Paradox affects fairness by demonstrating that some apportionment methods can produce unexpected and seemingly unfair results. When a state loses a seat after the total number of seats increases, it undermines the principle that more seats should not harm any state's representation. This paradox reveals that certain methods may not be monotonic, meaning that increasing the total seats does not always lead to non-decreasing allocations for all states. Recognizing this helps students critically evaluate different apportionment methods and their suitability for ensuring equitable representation.
The Alabama Paradox primarily affects apportionment methods based on largest remainders, such as Hamilton's method. In these methods, seats are first allocated based on quotas, and remaining seats are distributed according to fractional remainders. Because of this, increasing the total number of seats can change the distribution of remainders, causing some states to lose seats unexpectedly. In contrast, divisor methods like Jefferson's or Webster's methods are designed to avoid the Alabama Paradox by using a different approach to rounding and allocation, ensuring monotonicity in seat distribution.
While the Alabama Paradox was historically significant, modern apportionment systems often use divisor methods that avoid this paradox. For example, the Huntington-Hill method, currently used for U.S. House of Representatives apportionment, is designed to prevent such paradoxes by ensuring monotonicity. However, understanding the Alabama Paradox remains important for students because it illustrates potential pitfalls in allocation methods and the importance of choosing appropriate algorithms for fair representation. It also serves as a cautionary example in the design of apportionment systems worldwide.
The Alabama Paradox was discovered in 1880 during the apportionment of seats in the U.S. House of Representatives. When the total number of seats was increased from 299 to 300, the state of Alabama unexpectedly lost a seat under Hamilton's method of apportionment. This surprising outcome highlighted a flaw in the method and sparked significant debate about fair representation. The paradox is named after Alabama because it was the state that experienced this counterintuitive loss. This historical event is often studied to understand the limitations of certain apportionment methods and the need for more robust approaches.
