sphérique

**Sphérique**

The term *sphérique* refers to a spherical or rounded shape, often used in various fields such as mathematics, architecture, and design. In mathematics, a sphere is a perfectly symmetrical three-dimensional surface where every point on the surface is equidistant from a central point, known as the center. The equation of a sphere in three-dimensional Cartesian coordinates is given by (x - a)² + (y - b)² + (z - c)² = r², where (a, b, c) is the center and r is the radius.

In architecture and design, spherical structures are celebrated for their aesthetic appeal and functional efficiency. Examples include domes, which are often used in buildings to create spacious interiors while allowing natural light to enter. The Great Pyramid of Giza, one of the oldest and most iconic structures in Egypt, features a spherical influence in its overall design. Modern applications include spherical tanks for storing liquids or gases, as well as spherical mirrors used in telescopes and solar concentrators.

The word *sphérique* also relates to spherical photography, a technique where a camera is mounted on a spherical frame to capture a 360-degree view. This method is commonly used in virtual tours, video production, and immersive media to create a seamless, panoramic experience. Spherical video formats, such as 360-degree video, have gained popularity in virtual reality (VR) applications, enabling users to navigate and interact with their environment in a fully immersive manner.

Additionally, in meteorology, the term can describe spherical weather patterns or phenomena, such as the curvature of the Earth affecting wind and weather systems. The concept of a spherical Earth is fundamental to geography and navigation, influencing the design of maps and the study of global climate dynamics.
