Wundt measured mental processing speed by likening it to differences in stargazing measurements. It can be known only through extensive gravitational measurements and calculations. Biometrics is the technical term for body measurements and calculations. A further application is in the characterization of particles by optical scattering measurements. Accelerations can be defined through kinematic measurements. They are defined for practical operational measurements and assessment of doses in the body. The readings are taken by voltage measurements. Other prediction methods rely on other experimental measurements such as solubility. Errors can be detected by comparing the results of the two measurements. The total skull size is the sum of these two measurements. Thomson used data published by Regnault to calibrate his scale against established measurements. Each term is thus dependent on the exact measurements of a flow. Differences between left and right arm blood pressure measurements tend to be small. Mountain caribou are typically the most massive with the largest circumference measurements. Novae have some promise for use as standard candle measurements of distances.
