The scaling is uniform if and only if the scaling factors are equal (v x = v y = v z). If all except one of the scale factors are equal to 1, we have directional scaling. In the case where v x = v y = v z = k, scaling increases the area of any surface by a factor of k 2 and the volume of any solid object by a factor of k 3.
The number can also be interpreted as a fraction of a full turn between 0 (inclusive) and 1 (exclusive) represented in binary fixed-point format with a scaling factor of 1/2 n. Multiplying that fraction by 360° or 2π gives the angle in degrees in the range 0 to 360, or in radians, in the range 0 to 2π, respectively.
If S is an n × n shear matrix, then: S has rank n and therefore is invertible; 1 is the only eigenvalue of S, so det S = 1 and tr S = n; the eigenspace of S (associated with the eigenvalue 1) has n − 1 dimensions. S is defective; S is asymmetric; S may be made into a block matrix by at most 1 column interchange and 1 row interchange operation
Thus we can build an n × n rotation matrix by starting with a 2 × 2 matrix, aiming its fixed axis on S 2 (the ordinary sphere in three-dimensional space), aiming the resulting rotation on S 3, and so on up through S n−1. A point on S n can be selected using n numbers, so we again have 1 / 2 n(n − 1) numbers to describe any n × n ...
A flow is a process in which the points of a space continuously change their locations or properties over time. More specifically, in a one-dimensional geometric flow such as the curve-shortening flow, the points undergoing the flow belong to a curve, and what changes is the shape of the curve, its embedding into the Euclidean plane determined by the locations of each of its points.

N L is the nominal length of the tape as specified by its mark; K L is a known length; Corr is the ratio of measured to actual length , determined by measuring a known length. In the U.S., some tapes come with United States Bureau of Standards certifications establishing the correction needed per 100' of tape.
Your doctor will suspect osteoporosis if you have an overall height loss of 1.5 inches or more, or a height loss of 0.8 inches or more from your last measurement, Litt says.
Then, at a speed of 13 400 000 m/s (30 million mph, 0.0447 c) contracted length is 99.9% of the length at rest; at a speed of 42 300 000 m/s (95 million mph, 0.141 c), the length is still 99%. As the magnitude of the velocity approaches the speed of light, the effect becomes prominent.
