Lord Kelvin quotes

" All science is either physics or stamp collecting. " # Science and Scientists

" There cannot be a greater mistake than that of looking superciliously upon the practical applications of science. The life and soul of science is its practical application; and just as the great advances in mathematics have been made through the desire of discovering the solution of problems which were of a highly practical kind in mathematical science, so in physical science many of the greatest advances that have been made from the beginning of the world to the present time have been made in earnest desire to turn the knowledge of the properties of matter to some purpose useful to mankind.

" Until you can measure something and express it in numbers, you have only the begining of understanding. " # Understanding

" I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.

" Symmetrical equations are good in their place, but 'vector' is a useless survival, or offshoot from quaternions, and has never been of the slightest use to any creature. " # Industry # Humankind # Death and Dying

" Do not imagine that mathematics is hard and crabbed, and repulsive to common sense. It is merely the etherealization of common sense. " # Mathematics # Common Sense # Imagination
