humamity raw material source energy waste generation

"Humanity stands ... before a great problem of finding new raw materials and new sources of energy that shall never become exhausted. In the meantime we must not waste what we have, but must leave as much as possible for coming generations."

—Svante Arrhenius (1859-1927)

"Is the mean temperature of the ground in any way influenced by the presence of heat-absorbing gases in the atmosphere?"

beginning end subdivide part antiquity antiquity

"At first sight nothing seems more obvious than that everything has a beginning and an end, and that everything can be subdivided into smaller parts. Nevertheless, for entirely speculative reasons the philosophers of Antiquity, especially the Stoics, concluded this concept to be quite unnecessary. The prodigious development of physics has now reached the same conclusion as those philosophers, Empedocles and Democritus in particular, who lived around 500 B.C.E. and for whom even ancient man had a lively admiration."

—Svante Arrhenius (1859-1927)

physical chemistry reason natural science

"The theoretical side of physical chemistry is and will probably remain the dominant one; it is by this peculiarity that it has exerted such a great influence upon the neighboring sciences, pure and applied, and on this ground physical chemistry may be regarded as an excellent school of exact reasoning for all students of the natural sciences."

—Svante Arrhenius (1859-1927)
