vector

English

WOTD – 3 June 2006

Etymology

From Latin vector (“carrier, transporter”), from vehō (“I carry, I transport, I bear”).

The “person or entity that passes along an urban legend or other meme” sense derives from the disease sense.

The use of the term “vector” in mathematics was introduced by William Rowan Hamilton when he introduced the quaternion product.

Noun

vector (plural vectors)

1. (mathematics) A directed quantity, one with both magnitude and direction; the signed difference between two points.
   • 1914, The New Student's Reference Work:

     As examples of vector quantities may be mentioned the distance between any two given points, a velocity, a force, an acceleration, angular velocity, intensity of magnetization flux of heat.

2. (mathematics) An ordered tuple representing a directed quantity or the signed difference between two points.
3. (mathematics) Any member of a (generalized) vector space.

   The vectors in ${\mathbb {Q} }[X]$ are the single-variable polynomials with rational coefficients: one is $\textstyle x^{42}+{\frac {1}{137}}x-1$.

4. (aviation) A chosen course or direction for motion, as of an aircraft.
6. (epidemiology) A carrier of a disease-causing agent.
7. (sociology) A person or entity that passes along an urban legend or other meme.
8. (psychology) A recurring psychosocial issue that stimulates growth and development in the personality.
9. The way in which the eyes are drawn across the visual text. The trail that a book cover can encourage the eyes to follow from certain objects to others.(Can we add an example for this sense?)
10. (computing, operating systems) A memory address containing the address of a code entry point, usually one which is part of a table and often one that is dereferenced and jumped to during the execution of an interrupt.
11. (programming) A one-dimensional array.
    • 2004, Jesse Liberty, ‎Bradley L. Jones, Sams Teach Yourself C++ in 21 Days (page 694)

      To create a vector of students in a class, you will want the vector to be large enough […]

12. (molecular biology) A DNA molecule used to carry genetic information from one organism into another.

Usage notes

• (programming): The term vector is used loosely when the indices are not (either positive or non-negative) integers.
