geometer

As a result of his leadership, by the mid-1980s there was a vigorous interaction between quantum field theorists and geometers.

If you want a mathematical justification that a T-shirt and a pair of pants are different, you should turn to a topologist, not a geometer.

This turned out to be the larva of a geometer two inches long.

His father, like that of the illustrious geometer Lambert, was a tailor.

Let us, therefore, see the geometer at work and seek to catch his process.

No mathematical exactness without explicit proof from assumed principles—such is the motto of the modern geometer.

For the pure geometer himself, this faculty is necessary; it is by logic one demonstrates, by intuition one invents.
