"The development of a rational view of the nature of catalysis was thus absolutely dependent on the creation of the concept of the rate of chemical reaction."

"Flowers are the beautiful hairs of the Mother Spring! Don't pluck them!"

"Eagle's flight of loneliness soars so high Around its sigh, no more alone the sky Other birds remain away, clouds pass byBetween shrouds of life and haze sun rays die."

"Listen to what the sky is telling you."

"The moon hung over the planet Earth, a dead thing over a dying thing."

"Nature is the guardian of Africa. While the sun lights the African sky in day time, the moon begs the world to help her lighting Africa in the night."

"Nature never deceives us; it is we who deceive ourselves."

"When the ax came into the forest the trees said the handle is one of us."

"I went home and tried to sleep, but couldn't, so I stared up at the moon, watching how it's trailing edge faded into darkness, so close to being full, but not quite there. A pregnant moon, Grandma called it. Full almost to bursting, and ready to give birth to something unthinkable."

"The distinction between the old and the new formulations consisting in the incorporation of the concept of the rate of chemical reactions is so great that it immediately asserted itself in the objective development of catalysis."


"Soon afterwards I studied the inversion of sugar in the light of these considerations and immediately found that this classical reaction, too, was determined quantitatively by the same property of the acids, as was of course to be expected from the previous results."


"The well-known fact that the form of a specific substance, e.g. water, and hence its properties can alter without a change in composition was disposed of by the formal view that a physical, not a chemical, process was involved."


"It has pleased no less than surprised me that of the many studies whereby I have sought to extend the field of general chemistry, the highest scientific distinction that there is today has been awarded for those on catalysis."


"In specific circumstances the period of aging decline can set in earlier in a particular organ than in the organism as a whole which, in a certain general or theoretical sense, is left a cripple or invalid."


"We know from biology that new forms of organisms simulate their primitive form as closely as possible at first, even though obliged to exist under changed internal and external conditions."


"The individual organs follow the same pattern as the whole organism, i.e. they have their period of growth, of stationary, maximum activity and then of aging decline."


"In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely."


"For, with pure water the inversion of cane sugar scarcely proceeds and subsequently it required very thorough, difficult studies before this effect and its order of magnitude were established."
