Page 394 - 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 measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind...
Page 409 - It seems to me that the test of ' Do we or do we not understand a particular subject in physics ? ' is : ' Can we make a mechanical model of it ? ' I have an immense admiration for Maxwell's mechanical model of electromagnetic induction.
Page 397 - Within a finite period of time past, the earth must have been, and within a finite period of time to come, the earth must again be, unfit for the habitation of man as at present constituted, unless operations have been, or are to be performed, which are impossible under the laws to which the known operations going on at present in the material world are subject.
Page 406 - ... 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...
Page 397 - There is at present in the material world a universal tendency to the dissipation of mechanical energy. 2. Any restoration of mechanical energy, without more than an equivalent of dissipation, is impossible in inanimate material processes, and is probably never effected by means of organized matter either endowed with vegetable life or subjected to the will of an animated creature. 3. Within a finite...
Page 409 - I never satisfy myself until I can make a mechanical model of a thing.
Page 411 - I know no more of electric and magnetic force, or of the relation between ether, electricity, and ponderable matter, or of chemical affinity, than I knew and tried to teach to my students of natural philosophy fifty years ago in my first session as Professor.
Page 396 - It is impossible, by means of inanimate material agency, to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects.
