I don't like it when mathematicians who know much more than I do can't express themselves explicitly.

Mathematicians are like French people: whatever you tell them they translate it into their own language and turn it into something totally different.

Hua Luogeng is a mathematician.

That Space, as our mathematicians have it, is spoken of as having three dimensions, which one may call Length, Breadth, and Thickness, and is always definable by reference to three planes, each at right angles to the others.
