In The Big Problem of Small Change, Sargent and Velde apply a cashin-advance model to the history of coinage and to contemporary thought about coinage. They assert that their model accounts for puzzling observations involving the depreciation and disappearance of small coins. I question its usefulness for that purpose and for other issues pertaining to coinage. My main concern is that their mod...

Coinage metal cyanides (MCN) form photoluminescent 1D coordination polymers. The decoration of these chains with amine and phosphine ligands shifts the wavelength for photoluminescence into the visible region. Density-functional theory (DFT) and time-dependent DFT (TD-DFT) calculations of zigzag and helical models of decorated chains are used to show that the transitions that contribute to the ...

The reactivity of structurally identical silylene and stannylene [PhC(NtBu)2EN(SiMe3)2] (E = Si (1) and Sn (2)) towards coinage metals has been explored. While 1 has the propensity to form an adduct with coinage metals (4 and 5), 2 undergoes a ligand exchange reaction with copper halides and silver triflate leading to PhC(NtBu)2SnX (X = Br (6), Cl (7), and OSO2CF3 (8)) with concomitant formatio...

In The Genealogy of Morals, Nietzsche argues that "the mind of early man was preoccupied to such an extent with price-making . . . that in a certain sense this may be said to have constituted his thinking."' A fundamental change in price-making constitutes a fundamental change in thinking. The development of money was such a change. Although minting was not a great technological innovation, mon...

The coinage of Vijayanagar and the later successor state of Mysore is relatively unique among Indian coin series in that a number of coin types have close sculptural parallels. In this brief paper, I will point out a few of these, using two specific cases, reliefs of Hanumān and the gold varāhas of Hari Hara I and Bukka I, and the statue of Bālakṛṣṇa from the Kṛṣṇa Temple in Hampi and the Bālak...

Data from computational and experimental sources have been combined to address the bonding and structure of [RB(3-(R),5-(R)Pz)3]M(C2H4) complexes, where M ) Cu, Ag, Au. A κ3 to κ2 distortion of the scorpionate ligand was also studied. NMR properties were deemed to be the most useful in assessing the nature of the bonding in these complexes. Using computational recipes, 13C chemical shifts accur...
