Ion theory, first to predict greenhouse effect
Quotes by Svante Arrhenius
The temperature of the earth's surface is determined by the balance between the radiation received from the sun and the radiation emitted by the earth.
Any doubling of the percentage of carbonic acid in the air would raise the temperature of the earth's surface by 4°C; and if the carbonic acid were increased fourfold, the temperature would rise by 8°C.
The ocean acts as a great equalizer of temperature, and its influence on the climate is very considerable.
The quantity of carbonic acid in the atmosphere is subject to variations which may be of importance for the climate.
The earth's atmosphere acts like the glass of a hothouse, letting through the sun's rays but retaining the heat radiated from the ground.
The whole of the earth's past history is written in the rocks, and we have only to learn to read it.
The idea that life may be carried from one planet to another by means of spores is not new.
The theory of electrolytic dissociation has been of fundamental importance for the development of chemistry.
The properties of solutions are determined by the ions present in them.
The degree of dissociation increases with dilution.
The rate of chemical reactions depends on the concentration of the reacting substances.
The activation energy is a measure of the energy barrier that must be overcome for a reaction to occur.
The temperature coefficient of a reaction is a measure of how much the reaction rate increases for a given increase in temperature.
The study of solutions is one of the most important branches of physical chemistry.
The universe is a vast and complex system, and we are only beginning to understand its workings.
Science is the pursuit of truth, and it is a never-ending journey.
The greatest discoveries are often made by those who dare to challenge established ideas.
The future of humanity depends on our ability to understand and protect our planet.
The progress of science is a testament to the power of human reason.
The more we learn about the universe, the more we realize how much we still don't know.
