Philosophical Transactions" is paper written by John Tyndall is 1861 discussion the absorption of heat by gases. His paper is arguable the founding paper on climate science. Tyndall wrote: ‘if, as the above experiments indicate, the chief influence be exercised by aqueous vapour, every variation of this constituent must produce a change of climate. Similar remarks would apply to the carbonic acid [carbon dioxide] diffused through the air’.

John Tyndall's experiment started with shining a light beam through a falling stream of water. The tank of water in his experiment had a horizontal pipe extending out one side, allowing water to flow out in an arc to a collection pan on the floor. Tyndall directed a bright light into the pipe and the light rays traveled within the water until they were broken up by the turbulence of the water hitting the collection pan. This experiment demonstrated "total internal reflection".

In Hulster Hall, Tyndall pronounced "We claim, and we shall wrest from theology, the entire domain of cosmological theory. All schemes and systems which thus infringe upon the domain of science must, insofar as they do this, submit to its control, and relinquish all thought of controlling it." Tyndall was a strong advocate for scientific naturalism.

Tyndallization is a process developed by John Tyndall in 1877 used to sterilize food by alternate heating and cooling. This experiment proved the existence of heat resistance forms of bacteria after observing boiling the infusion for longer than 5 hours was not enough to sterilize it. He revealed that bacteria has both thermal-stable and thermal-labile phases. https://youtu.be/zW-xzEhBzWI
