Solid Geometry Quotes & Sayings

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 ... — Oliver Heaviside

[Not enough is known about solid geometry] and for two reasons: in the first place, no government places value on it; this leads to a lack of energy in the pursuit of it, and it is difficult. In the second place, students cannot learn it unless they have a teacher. But then a teacher can hardly be found ... — Plato

This has been my difficulty. The difficulty with my life. Those well-built trig points, those physical determinants of parents, background, school, family, birth, marriage, death, love, work, are themselves as much in motion as I am. What should be stable, shifts. What I am told is solid, slips. The sensible strong ordinary world of fixity is folklore. The earth is not flat. Geometry cedes to algebra. The Greeks were wrong. — Jeanette Winterson

Considerable obstacles generally present themselves to the beginner, in studying the elements of Solid Geometry, from the practice which has hitherto uniformly prevailed in this country, of never submitting to the eye of the student, the figures on whose properties he is reasoning, but of drawing perspective representations of them upon a plane ... I hope that I shall never be obliged to have recourse to a perspective drawing of any figure whose parts are not in the same plane. — Augustus De Morgan

The ludicrous state of solid geometry made me pass over this branch. — Plato
