Periodic tables (PTs) are the ‘ultimate paper tools’ of general and inorganic chemistry. There are three fields of open questions concerning the relation between PTs and physics: (i) the relation between the chemical facts and the concept of a periodic system (PS) of chemical elements (CEs) as represented by PTs; (ii) the internal structure of the PS; (iii)␣The relation between the PS and atomistic quantum chemistry. The main open questions refer to (i). The fuzziness of the concepts of chemical properties (...) and of chemical similarities of the CE and their compounds guarantees the autonomy of chemistry. We distinguish between CEs, Elemental Stuffs and Elemental Atoms. We comment on the basic properties of the basic elements. Concerning (ii), two sharp physical numbers (nuclear charge and number of valence electrons) and two coarse fuzzy ranges (ranges of energies and of spatial extensions of the atomic orbitals, AOs) characterize the atoms of the CEs and determine the two-dimensional structure of the PS. Concerning (iii), some relevant ‘facts’ about and from quantum chemistry are reviewed and compared with common ‘textbook facts’. What counts in chemistry is the whole set of nondiffuse orbitals in low-energy average configurations of chemically bonded atoms. Decisive for the periodicity are the energy gaps between the core and valence shells. Diffuse Rydberg orbitals and minute spin–orbit splittings are important in spectroscopy and for philosophers, but less so in chemical science and for the PS. (shrink)

A Thousand Plateaus is the engaging and influential second part of Capitalism and Schizophrenia, the remarkable collaborative project written by the philosopher Gilles Deleuze and the psychoanalyst Félix Guattari. This hugely important text is a work of staggering complexity that made a major contribution to contemporary Continental philosophy, yet remains distinctly challenging for readers in a number of disciplines. Deleuze and Guattari's 'A Thousand Plateaus': A Reader's Guide offers a concise and accessible introduction to this extremely important and yet challenging (...) work. Written specifically to meet the needs of students coming to Deleuze and Guattari for the first time, the book offers guidance on: - Philosophical and historical context - Key themes - Reading the text - Reception and influence - Further reading.

This collection of previously unpublished essays is a celebration of the life and thought of a beloved professor who died of cancer in 1983. (pb).

_Nomad Citizenship_ argues for transforming our institutions and practices of citizenship and markets in order to release society from dependence on the state and capital. It changes Deleuze and Guattari’s concept of nomadology into a utopian project with immediate practical implications, developing ideas of a nonlinear Marxism and of the slow-motion general strike. Responding to the challenge of creating philosophical concepts with concrete applications, Eugene W. Holland looks outside the state to analyze contemporary political and economic development using the (...) ideas of nomad citizenship and free-market communism. Holland’s nomadology seeks to displace capital-controlled free markets with truly free markets. Its goal is to rescue market exchange, not perpetuate capitalism—to enable noncapitalist markets to coordinate socialized production on a global scale and, with an eye to the common good, to liberate them from capitalist control. In suggesting the slow-motion general strike, Holland aims to transform citizenship: to renew, enrich, and invigorate it by supplanting the monopoly of state citizenship with plural nomad citizenships. In the process, he offers critiques of both the Clinton and Bush regimes in the broader context of critiques of the social contract, the labor contract, and the form of the state itself. (shrink)

Intercellular signaling plays an important role in spatially regulated developmental processes. Myxococcus xanthus C signal transmission during fruiting body formation requires motile, densely packed, well aligned cells. tThe fruiting body consists of two domains: an outer domain which has densely packed, well aligned, motile cells: and an inner domain of more loosely packed, non‐motile, sporulating cells. The two domains are characterized by different patterns of C‐dependent gene expression, which begins in the outer domain where C‐signaling is most efficient, and reaches (...) its maximum in the inner domain. These domains may be maintained by a dynamic mechanism which relies on passive transport of the sporulating cells from the outer domain, where sporulation is initiated, to the inner domain by the motile cells in the outer domain.
