Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The product of two real vectors in three dimensions that is itself a vector at right angles to both the original vectors. Its magnitude is the product of the magnitudes of the original vectors and the sine of the angle between their directions.
- ‘We can use the direction perpendicular to this plane to give us the direction of our vector product.’
- ‘As the name says, a scalar product of two vectors results in a scalar quantity, and a vector product in a vector quantity.’
- ‘The vector product is, from the properties of determinants, linear in both its vector factors.’
- ‘This shows that the vector product of two direct lattice vectors is easily expressed in terms of the basic reciprocal vectors.’
- ‘Today's vector products are a watered-down version of quaternion multiplication.’
