In the natural sciences, a vector quantity (also known as a vector physical quantity, physical vector, or simply vector) is a vector-valued physical quantity. [9] [10] It is typically formulated as the product of a unit of measurement and a vector numerical value (), often a Euclidean vector with magnitude and direction.
[1] Between 1999 and 2003, Article 32 of the 1992 law stated that the term of protection for photographs was to be calculated starting from the 1st of January of the year of their actual completion (and not starting from the next calendar year as is the case in many countries). The term of protection for a photograph completed on December 31 ...
The Helmholtz decomposition in three dimensions was first described in 1849 [9] by George Gabriel Stokes for a theory of diffraction. Hermann von Helmholtz published his paper on some hydrodynamic basic equations in 1858, [10] [11] which was part of his research on the Helmholtz's theorems describing the motion of fluid in the vicinity of vortex lines.

Multiplication by 1/2 is required to properly describe the power flow since the magnitudes of E m and H m refer to the peak fields of the oscillating quantities. If rather the fields are described in terms of their root mean square (RMS) values (which are each smaller by the factor 2 / 2 {\displaystyle {\sqrt {2}}/2} ), then the correct average ...
