  2. Vernier scale - Wikipedia

    en.wikipedia.org/wiki/Vernier_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. If you put the two scales together with zero points aligned, the first mark on the vernier scale is 1/10 short of the first main scale mark, the second is 2/10 short, and so on up to the ninth mark, which is misaligned by 9/10.

  3. Least count - Wikipedia

    en.wikipedia.org/wiki/Least_Count

    In the science of measurement, the least count of a measuring instrument is the smallest value in the measured quantity that can be resolved on the instrument's scale. [1] The least count is related to the precision of an instrument; an instrument that can measure smaller changes in a value relative to another instrument, has a smaller "least ...

  4. Pierre Vernier - Wikipedia

    en.wikipedia.org/wiki/Pierre_Vernier

    The main scale reading is the rightmost graduation that is to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales. The 0.02 mm engraving indicates the caliper's accuracy and is the "Vernier constant" for this scale. He was born in Ornans, France, in 1580. He was ...

    For example, the constant π may be defined as the ratio of the length of a circle's circumference to its diameter. The following list includes a decimal expansion and set containing each number, ordered by year of discovery. The column headings may be clicked to sort the table alphabetically, by decimal value, or by set.

  6. Vernier acuity - Wikipedia

    en.wikipedia.org/wiki/Vernier_acuity

    Vernier acuity is measured by asking participants to judge the offset between two parallel line segments with both eyes (binocular vision) or with each eye individually (monocular vision). [10] Vernier measures in infants and non-verbal children can be done using the preferential-looking technique [11] or by electrophysiological techniques. [12 ...

  9. Cavendish experiment - Wikipedia

    en.wikipedia.org/wiki/Cavendish_experiment

    After converting to SI units, Cavendish's value for the Earth's density, 5.448 g cm −3, gives G = 6.74 × 10 −11 m 3 kg –1 s −2, [24] which differs by only 1% from the 2014 CODATA value of 6.67408 × 10 −11 m 3 kg −1 s −2. [25] Today, physicists often use units where the gravitational constant takes a different form.
