“This fixes as it were the latitude and longitude of each discovery, and enables us to place it in that part of the map of human knowledge which it ought to occupy. It likewise enables us to use it in taking bearings and distances, and in shaping our course when we go in search of new discoveries.”

Virtue never dwelt long with filth; nor do I believe there ever was a person scrupulously: attentive to cleanliness, who was a consummate villain.

To engage in experiments on heat was always one of my most agreeable employments.

So great is the effect of cleanliness upon man, that it extends even to his moral character.

Do I believe in ghosts? Of course I do. So do you. Deep in the souls of the most sophisticated of us is lurking a fear of the supernatural which all the discoveries of scientists cannot eradicate.

To my mind the single essential element on which all discoveries will be dependent is human freedom.

Discovery is new beginning. It is the origin of new rules that supplement, or even supplant, the old.

It was a huge deal, a huge musical discovery that became life lessons learned. You can’t return from having an experience like that. The Blind Boys are truly the deepest well of American musical heritage you can discover.

The basis of the discovery is imagination, careful reasoning and experimentation where the use of knowledge created by those who came before is an important component.

Every time a significant discovery is being made one sets in motion a tremendous activity in laboratories and industrial enterprises throughout the world.

Life throws stones at you, but your love and your dream change those stones into the flowers of discovery. Even if you lose, or are defeated by things, your triumph will always be exemplary. And if no one knows it, then there are places that do.

Learning is a process of mutual discovery for teacher and pupil. Keep an open mind to their unexpected responses.
