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.
