Cargill Gilston Knott quotes:

Scientific theory and its application to the growing needs of mankind advance hand in hand.

The assumption that the square of a unit vector is positive unity leads to an algebra whose characteristic quantities are non-associative.

We are perhaps too near the age of transition to see clearly the interplay of all that made for progress. Each of us has had his own peculiar training, his own personal contact with the mighty ones of the immediate past; and this forms as it were a telescopic tube determining limits to our field of vision. No doubt we may range the whole horizon; but after all we look from our own point of vantage.

What may appear as a towering peak to one may seem but an ordinary eminence to another.
