This concept extends beyond geometry to functions, signals, and data analysis, where orthogonality implies independence and non-interference among components.
Concept
Projection is a mathematical and psychological concept that involves mapping or transferring characteristics, values, or data from one space or entity to another. In mathematics, it often refers to the method of reducing dimensions, while in psychology, it describes the defense mechanism where individuals attribute their own undesirable traits onto others.
Concept
Linear geometry is a branch of geometry that deals with figures and properties that are defined using linear equations and inequalities, focusing on lines, planes, and their intersections. It serves as the foundation for understanding more complex geometric structures and is essential in fields like computer graphics, physics, and engineering.

Somatic gene therapy involves the introduction, removal, or alteration of genes within the somatic cells of a patient to treat or prevent disease. Unlike germline gene therapy, changes made in somatic cells are not passed down to future generations, focusing solely on treating the individual patient.
The three-dimensional coordinate system is a framework for locating points in space using three coordinates, typically labeled as x, y, and z.

Therapeutic gene delivery is a cutting-edge approach in medicine that involves introducing genetic material into a patient's cells to treat or prevent disease. This technology holds promise for treating genetic disorders, cancers, and viral infections by correcting defective genes or providing new functions to cells.

Concept
Three-dimensional geometry is the study of shapes and figures in a space defined by three dimensions: length, width, and height. It extends the principles of two-dimensional geometry into a three-dimensional context, allowing for the analysis and understanding of objects like spheres, cubes, and pyramids.

Component-wise operations are like playing with blocks where you match and add or multiply one block from one pile with the same block from another pile. It's a fun way to make new piles by doing the same thing to each matching block, one by one.
Concept
When things are linearly dependent, it means you can make one thing by using some parts of the other things. Imagine having a box of crayons, and you can make the color green by mixing blue and yellow crayons together; that's like being linearly dependent.
