Understanding Polygons, Quadrilaterals, and Polyhedrons
Understanding Polygons
A polygon is a part of a plane delimited by a closed polygonal path (it is called a polygonal region). It can be:
- Convex: Prolongation of all segments of the polygonal path divides the plane into two semi-planes, and the polygonal path is all in the same semi-plane.
- Concave: Prolongation of at least one segment of the polygonal path divides the plane into two parts, each one in different semi-planes.
- Regular: When all the sides and angles are equal.

Photosynthesis: A Unique Mechanism of Energy Input
Photosynthesis is a unique mechanism for energy input into the biosphere. Light is captured and converted into chemical energy in the form of organic matter, stored as carbohydrates, producing free O2. This process distinguishes the plant kingdom. It is influenced by the following factors: light, temperature, air humidity, water availability, carbon dioxide (CO2), and nutrients. Free oxygen in the atmosphere reaches 21%.

Descartes’ Methodical Doubt
Stages of Methodical Doubt
The understanding must find fundamental truths within itself, truths that are absolutely certain and beyond any doubt. The search for this starting point requires a prior task: to remove all knowledge, ideas, and beliefs that do not possess absolute certainty. We must eliminate everything that can be doubted. Hence, Descartes begins with doubt.
The first reason to doubt our knowledge is the fallibility of the senses: the senses deceive us at times.

Major Impact of Social Changes and Scientific Developments
