"Eigen" Natural Recordings by Native Speakers
The word "eigen" has several meanings depending on the context. Here are a few common ones:
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.
Example sentence: "The eigenvectors of the matrix represent the directions that are unchanged under the transformation."
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.
Example sentence: "The energy eigenstates of the atom represent the possible orientations of the atom that are unchanged under rotation."
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.
Example sentence: "The genomic eigenvalues of the species represent the regions of the genome that are most evolutionarily conserved."
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.
Eidolic refers to something that has a ghostly or spectral appearance, often used to describe a phantom or a hallucination, especially one that is seen or perceived visually.
The word "eidos" is a Greek term that refers to a form or appearance, especially in philosophy. In Western philosophy, eidos was used to describe the idea of a universal or eternal form that underlies the imperfect and changing world we experience through our senses. This concept is closely related to the philosopher Plato's theory of forms, which posits that there is a higher, eternal realm of abstract Forms or Ideas that are the true and eternal reality, and that the world we experience is only an imperfect reflection of these Forms. In other words, eidos refers to the abstract, ideal, or essential nature of something, rather than its physical appearance or manifestation.
