Subsequent vector graphics systems, most of which iterated through dynamically modifiable stored lists of drawing instructions, include the IBM 2250, Imlac PDS-1, and DEC GT40. There was a video game console that used vector graphics called Vectrex as well as various arcade games like Asteroids , Space Wars , Tempest and many cinematronics ...
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.
The index is not defined at any non-singular point (i.e., a point where the vector is non-zero). It is equal to +1 around a source, and more generally equal to (−1) k around a saddle that has k contracting dimensions and n−k expanding dimensions. The index of the vector field as a whole is defined when it has just finitely many zeroes. In ...

The costs of food eaten at home were 1.6% higher last month than they were the same time last year — a smaller uptick than the 2.7% annual inflation rate overall but accelerating 0.5% from the ...
By referring collectively to e 1, e 2, e 3 as the e basis and to n 1, n 2, n 3 as the n basis, the matrix containing all the c jk is known as the "transformation matrix from e to n", or the "rotation matrix from e to n" (because it can be imagined as the "rotation" of a vector from one basis to another), or the "direction cosine matrix from e ...
In 2024, the wide, wide world of sports saw repeat champions, first-time titlists, a grand Paris summer and some epic fails. The winners and losers:
For the first time in over a decade, obesity rates in the United States may finally be heading in the right direction and new weight loss drugs like semaglutide could be part of the reason why. A ...
