TO
THE PRESIDENT OF THE
MASSACHUSETTS INSTITUTE OF TECHNOLOGY
TO MY COLLEAGUES THERE
AND TO ITS STUDENT BODY
TO WHOSE INTEREST AND ATTENTION THESE
LECTURES ARE INDEBTED
THEY ARE APPRECIATIVELY INSCRIBED
“Si je n’étais pas devenu général en chef et l’instrument du sort d’un grand people, j’aurais couru les bureaux et les salons pour me mettre dans la dépendance de qui que ce fût, en qualité de ministre ou d’ambassadeur? Non, non! je me serais jeté dans l’étude des sciences exactes. J’aurais fait mon chemin dans la route des Galilée, des Newton. Et puisque j’ai réussi constamment dans mes grandes entreprises, eh bien, je me serais hautement distingué aussi par des travaux scientifiques. J’aurais laissé le souvenir de belles découvertes. Aucune autre gloire n’aurait pu tenter mon ambition.”
—Napoleon Iᴱᴿ, quoted by Arago.
The substance of the following pages was written and presented in a university course of lectures before the Massachusetts Institute of Technology—in February and March of this year. The kind interest with which the lectures were received, not only by the students and professional bodies, but by the public, was followed by an immediate request from The Macmillan Company to issue them in book form, and as such they now appear.
PERCIVAL LOWELL.
