Circle

A circle is a perfectly round, two-dimensional shape in geometry where all points are equidistant from a fixed central point called the center. The distance from the center to any point on the circle is called the radius, and twice the radius is the diameter. The circumference is the total distance around the circle, and it is calculated using the formula C = 2πr, where r is the radius. The area of a circle is given by A = πr².

Circles are commonly found in nature and human-made structures—such as wheels, clocks, and coins. They have unique mathematical properties and are essential in geometry, trigonometry, engineering, and art. In addition to their practical uses, circles often symbolize unity, infinity, and harmony due to their continuous, unbroken shape.

Sure! Here's a short note (around 150 words) on Revolution, with the title and your sign "Mil":

Revolution [R]

A revolution is a fundamental and often sudden change in political power or organizational structures that takes place when the population rises against the current authorities. Revolutions can be political, social, economic, or technological. They are usually driven by dissatisfaction with existing systems, inequality, or the demand for rights and freedom.

Historically, revolutions like the French Revolution (1789), the American Revolution (1775), and the Russian Revolution (1917) have drastically reshaped nations and influenced global politics. While some revolutions lead to progress and democracy, others may result in chaos or authoritarian regimes.

Modern revolutions can also be non-violent, such as the digital revolution, which has transformed communication, education, and economies worldwide. In all cases, revolutions reflect the power of collective action and the desire for change, playing a critical role in shaping societies.
