However, a decade after Penrose demonstrated his Penrose Tilings mineralogists discovered quasicrystals. ❋ Unknown (2007)
That was why when originally conceived, the expedition was to carry a full complement of botanists, mineralogists, and other naturalists, some of whom, notably Asa Gray, were preeminent scholars; others like geologist James Eights had been invited because of previous field work in Antarctica and the southern Pacific. ❋ Unknown (2009)
They have high melting points, are dense or heavy (mineralogists say they have a high specific gravity), and are very non-reactive to other elements and ions. ❋ Unknown (2008)
It is rarely found as crystals, but is commonly found as what mineralogists describe as foliated masses. ❋ Unknown (2008)
One long-standing trajectory in the historiography of chemistry suggests that the eighteenth century holds little worthy of study until its later years. 5 Although understanding of the foundations of chemistry had advanced during the seventeenth century through the work of natural philosophers such as Robert Boyle, mineralogists such as Johann Henckel, and iatrochemists such as Johann Glauber, the discipline operated on instinct rather than any concrete methodology. ❋ Unknown (2006)
These layers can be seen in muscovite mica specimens because it can be split (mineralogists call this feature cleavage) into very thin, flexible, transparent layers. ❋ Unknown (2008)
The name was officially proposed to mineralogists by the German theologian and philosopher, Albertus Magnus. ❋ Unknown (2008)
He claimed a broad potential audience for his work: artists, artisans, entomologists, mineralogists and other scientists, experts on painting, amateurs of the arts, and the general public. ❋ Unknown (2006)
In diamond, they attach in a three-dimensional manner that mineralogists describe as a framework. ❋ Unknown (2007)
Cleavage is the term used by mineralogists to describe the way some minerals break into flat surfaces. ❋ Unknown (2007)
Petroleum geologists and mineralogists often presume, just as Ricardo did, that the best quality resources are used first even though history shows that a significant portion of the best quality resources are frequently not discovered until poorer quality resources have already been used. ❋ Unknown (2007)
In this derogatory statement he includes anyone who disagrees with him – the sedimentologists, mineralogists and geochemists along with the biostratigraphers. ❋ Unknown (2006)
Savants, poets, philosophers, foreign mineralogists, statesmen, after conversing in the morning with me, will visit her salon in the evening. ❋ Unknown (2003)
Anyhow, the deputation of distinguished geologists and mineralogists from Paris and Berlin were there in the most magnificent and appropriate dress, for there are no men who like wearing their decorations so much as the men of science — as anybody knows who has ever been to a soiree of the Royal Society. ❋ Unknown (2003)
The turquoise-gangue from Ziba (Chap. XII.) was pronounced, by the inexpert mineralogists at the Citadel, Cairo, who attempted criticism, to be carbonate of copper, because rich silicates of that metal were shown at the Exposition. ❋ Unknown (2003)
Never had mineralogists found themselves in so marvellous a situation to study nature in situ. ❋ Unknown (2003)
To this end, he brought with him more than 500 civilians, including about 150 biologists, mineralogists, linguists, mathematicians, chemists, and other scholars. ❋ Unknown (1999)
Now in command of the ` utile 'part of the country, Kabila has to decide whether he should move on what the mineralogists regard as the ` inutile' (useless) part - the chaotic and largely economically worthless quarter that includes the capital Kinshasa. ❋ Unknown (1997)
