Myopia; Other names: near-sightedness, short-sightedness: Diagram showing changes in the eye with myopia: Specialty: Ophthalmology, optometry: Symptoms: Distant objects appear blurry, close objects appear normal, headaches, eye strain [1]
Szemerényi's law, in Proto-Indo-European phonology: word-final clusters of vowels (V), resonants (R) and either *s or *h 2 are simplified by dropping the word-final fricative (*h 2 was phonetically itself probably a back fricative), with compensatory lengthening of the preceding vowel.
Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in dim light ...
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in ...
In multivariate statistics, a scree plot is a line plot of the eigenvalues of factors or principal components in an analysis. [ 1] The scree plot is used to determine the number of factors to retain in an exploratory factor analysis (FA) or principal components to keep in a principal component analysis (PCA).
In physics, the Rayleigh–Jeans law is an approximation to the spectral radiance of electromagnetic radiation as a function of wavelength from a black body at a given temperature through classical arguments. For wavelength λ, it is where is the spectral radiance (the power emitted per unit emitting area, per steradian, per unit wavelength ...
The results from the most basic double slit experiment, the observation of an interference pattern, is explained by wave interference from the two paths to the screen from each of the two slits. [9] The single-particle results show that the waves are probability amplitudes which square to produce a probability distribution. [9]
Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science community in an analytical technique called ...
