A subject's vernier (IPA: / ˈ v ɜːr n ɪər /) acuity is the smallest visible offset between the stimuli that can be detected. Because the disalignments are often much smaller than the diameter and spacing of retinal receptors, vernier acuity requires neural processing and "pooling" to detect it. Because vernier acuity exceeds acuity by far ...
Yet spatial distinctions can be made on a finer scale still: misalignment of borders can be detected with a precision up to 10 times better than visual acuity, as already shown by Ewald Hering in 1899. [1] This hyperacuity, transcending by far the size limits set by the retinal 'pixels', depends on sophisticated information processing in the brain.
The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. So for a vernier with a constant of 0.1, each mark on the vernier is spaced 9/10 of those on the main scale.
Other examples of perceptual learning in the natural world include the ability to distinguish between relative pitches in music, [24] identify tumors in x-rays, [25] sort day-old chicks by gender, [26] taste the subtle differences between beers or wines, [27] identify faces as belonging to different races, [28] detect the features that ...

Vernier himself used to say that his invention was a perfected nonius and for a long time it was known as the “nonius”, even in France. [7] In some languages, the Vernier scale is still named after Nunes, for example nonieskala in Swedish. Pedro Nunes also worked on some mechanics problems, from a mathematical point of view.
(Reuters) - The Biden administration on Friday canceled another $4.28 billion in student debt for nearly 55,000 public service workers, the U.S. Department of Education said in a statement. Friday ...
