Vector Quotes (3 quotes)

As to the need of improvement there can be no question whilst the reign of Euclid continues. My own idea of a useful course is to begin with arithmetic, and then not Euclid but algebra. Next, not Euclid, but practical geometry, solid as well as plane; not demonstration, but to make acquaintance. Then not Euclid, but elementary vectors, conjoined with algebra, and applied to geometry. Addition first; then the scalar product. Elementary calculus should go on simultaneously, and come into vector algebraic geometry after a bit. Euclid might be an extra course for learned men, like Homer. But Euclid for children is barbarous.

Force, then, is Force, but mark you! Not a thing,

Only a Vector;

Thy barbθd arrows now have lost their sting,

Impotent spectre!

Thy reign, O force! is over. Now no more

Heed we thine action;

Repulsion leaves us where we were before,

So does attraction.

Both Action and Reaction now are gone.

Just ere they vanished,

Stress joined their hands in peace, and made them one;

Then they were banished....

This maze of symbols, electric and magnetic potential, vector potential, electric force, current, displacement, magnetic force, and induction, have been practically reduced to two, electric and magnetic force.
