The Combustion of a Candle Resembles the Combustion Withi...
Now I must take you to a very interesting part of our subject—to the relation between the combustion of a candle and that living kind of combustion which goes on within us. In every one of us there is a living process of combustion going on very similar to that of a candle, and I must try to make that plain to you. For it is not merely true in a poetical sense—the relation of the life of man to a taper; and if you will follow, I think I can make this clear.Folksonomies: respiration

Faraday Predicts the Electric Nature of the Atom
Although we know nothing of what an atom is, yet we cannot resist forming some idea of a small particle, which represents it to the mind ... there is an immensity of facts which justify us in believing that the atoms of matter are in some way endowed or associated with electrical powers, to which they owe their most striking qualities, and amongst them their mutual chemical affinity.Summarizing his investigations in electrolysis.

The Charcoal Produced by Respiration
A man in twenty-four hours converts as much as seven ounces of carbon into carbonic acid; a milch cow will convert seventy ounces, and a horse seventy-nine ounces, solely by the act of respiration. That is, the horse in twenty-four hours burns seventy-nine ounces of charcoal, or carbon, in his organs of respiration to supply his natural warmth in that time ..., not in a free state, but in a state of combination.According to Faraday, a horse produces 79oz of charcoal in 24 hours just by breathing.

Herschel Compares Scientific Discovery to Columbus' Explo...
Herschel prophetically implied that electricity and electro-magnetism still hid many secrets, and that their investigation would become the leading science of the new age. This would indeed be Faraday’s coming field of triumph. He summarised (paragraph no. 376) this pursuit in the image of a great and noble sea voyage of exploration. ‘There is something in this which reminds us of the obstinate adherence of Columbus to his notion of the necessary existence of the New World; and the whole ...Through analogies and parallels the scientists finds branches to connect fields of knowledge.

Davy VS Gay-Lussac in the Race to Discover Iodine
He was warmly received by Cuvier, Ampère and Berthollet, but got into an awkward priority dispute with the gifted young chemist Joseph Gay-Lussac. Gay-Lussac, Davy’s exact contemporary, had made a popular name in France with his intrepid ballooning exploits, and had been hard on Davy’s heels with potassium and sodium experiments. Both were now given by the Académie des Sciences a newly isolated substance to analyse: a strange violet crystal recently found as a byproduct of gunpowder man...Still disputed as to who won the race.
