He plucks the pearls that stud the deep Admiring Beauty’s lap to fill;
He breaks the stubborn Marble’s sleep,
Rocks disappear before his skill:
With thoughts that swell his glowing soul
He bids the ore illume the page,
And, proudly scorning Time’s control,
Commences with an unborn age.
Written for the Mechanics Celebration (1824). In 'Art—An Ode', as quoted and cited in Alpheus Cary, An Address Delivered Before the Massachusetts Charitable Mechanic Association (October 7th, 1824) (1824), 49.

We divorced ourselves from the materials of the earth, the rock, the wood, the iron ore; we looked to new materials which were cooked in vats, long complex derivatives of urine which we called plastic. They had no odor of the living, ... their touch was alien to nature. ... [They proliferated] like the matastases of cancer cells.
The Idol and the Octopus: political writings (1968), 83 and 118.

Where there is cinnabar above, yellow gold will be found below. Where there is lodestone above, copper and gold be found below. Where there is calamine above, lead, tin, and red copper will be found below. Where there is haematite above, iron will be found below. Thus it can be seen that mountains are full of riches.
From Guo Me-ruo et al., Collections of Rectifications of the Book of Guang Zi (1956), 146-7. Trans. Yang Jing-Yi.
Science quotes on:  |  Copper (18)  |  Gold (55)  |  Iron (53)  |  Lead (101)  |  Mining (11)  |  Tin (11)

Who would not have been laughed at if he had said in 1800 that metals could be extracted from their ores by electricity or that portraits could be drawn by chemistry.
[Commenting on Becquerel’s process for extracting metals by voltaic means.]
Letter (20 Aug 1847), The Letters of Faraday and Schoenbein, 1836-1862 (1899), footnote, 209.
Science quotes on:  |  Henri Becquerel (5)  |  Chemistry (239)  |  Drawing (18)  |  Electricity (121)  |  Extraction (5)  |  Laugh (18)  |  Portrait (2)


Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
