8 unusual facts about Euclidean vector


Componentwise inequality

The vectors do not have to be real, they can be from any space in which the inequality relation is defined.

End-to-end vector

In the physical chemistry study of polymers, the end-to-end vector is the vector that points from one end of a polymer to the other end.

History of geomagnetism

At a given location, a full representation of the Earth's magnetic field requires a vector with three coordinates (see figure).

Machine tool

For example, several cams, no one of which directly matches the desired output shape, can actuate a complex toolpath by creating component vectors that add up to a net toolpath.

Neutral buoyancy simulation as a training aid

It is the inability to use weight in any vector in EVA coupled with the encumbrance of the pressure suit that makes task performance difficult.

Astronauts rehearse Extra-vehicular activity tasks in underwater neutral buoyancy before attempting those tasks in space to gain an understanding that they cannot use their weight to provide a force and that they may move or reposition themselves if they provide a propulsive force in any vector, either planned or inadvertent.

The individual feels gravity standing on the ice but they can’t use their weight to provide traction and they can’t shift their weight to provide force in a horizontal vector so they can’t force the door.

Whipcracking

Since momentum is a vector, it has a direction, and does not pass through any bend that reverses the direction of movement in the body of the whip − such as the one that occurs when a half wave shape moves down a whip.
