Eigen
The word "eigen" has several meanings depending on the context. Here are a few common ones:<br><br>1. In mathematics, "eigen" refers to something that remains unchanged after a transformation, such as a vector or a linear transformation. For example, the eigenvalue of a matrix is a scalar that, when multiplied by the matrix, results in a new matrix that is proportional to the original matrix.<br><br>Example sentence: "The eigenvectors of the matrix represent the directions that are unchanged under the transformation."<br><br>2. In physics and chemistry, "eigen" refers to a characteristic property or feature of a system that remains unchanged under certain conditions. For example, the eigenvalue of a quantum mechanical Hamiltonian represents the energy of a system that is unchanged under a particular symmetry operation.<br><br>Example sentence: "The energy eigenstates of the atom represent the possible orientations of the atom that are unchanged under rotation."<br><br>3. In biology, "eigen" can refer to a characteristic or trait that is unchanged under certain conditions, such as environmental factors. For example, the genomic eigenvalue of an organism represents the parts of the genome that are most important for its survival and reproduction.<br><br>Example sentence: "The genomic eigenvalues of the species represent the regions of the genome that are most evolutionarily conserved."<br><br>In general, the word "eigen" refers to something that is intrinsic or fundamental to a system or entity, and remains unchanged under certain transformations or conditions.
Eigenfunction
An eigenfunction is a function that, when acted upon by a linear operator, is scaled or transformed. In other words, it is a function that is unchanged except for a scaling or change of sign when multiplied by a constant, which is the eigenvalue of the linear operator.
Eigengrau
Eigengrau is a term used to describe the grey or grayish color that the brain typically perceives when the eyes are closed in a dark or dimly lit environment. It is also referred to as the "independent grey" or "native gray".
Eigenvalue
An eigenvalue is a scalar that characterizes the amount of change applied to a linear transformation. In simple terms, it is a value that is associated with a square matrix, and it represents how the matrix affects the inputted data.<br><br>When a matrix A is applied to a vector v, the resulting vector Av is scaled by some factor. This factor is the eigenvalue of the matrix A corresponding to the eigenvector v. In other words, if v is an eigenvector of A with eigenvalue λ, then Av λv.<br><br>Eigenvalues are used extensively in many areas of mathematics, science, and engineering. Some of the applications include linear algebra, differential equations, Markov chains, and signal processing.<br><br>For instance, in physics, eigenvalues can be used to describe the energy levels of a system. In computer science, eigenvalues can be used for clustering and dimensionality reduction.<br><br>In summary, eigenvalues are a fundamental concept in linear algebra that help us understand how matrices transform vectors, and they have numerous applications in various fields.

Eikon
The word "eikon" comes from the Greek language and means "image" or "icon". In Christian theology, it is used to refer to the image of God in humanity. In iconography, it refers to a representation of a holy person or event. In a broader sense, it can refer to any visual representation or likeness of a person or thing.
Eikonal
The word "eikonal" refers to a mathematical concept in physics, particularly in the study of wave propagation and optics. Specifically, it refers to a surface or a field that satisfies a particular differential equation, known as the eikonal equation.
