Defence of Planetary Conjunctions for Early Chinese Chronology Is Unmerited
Pankenier (2007) has responded to the critique by Keenan (2002) of astro-historiographic chronologies of early China. The arguments of Pankenier are assessed herein; the conclusion is that the arguments have negligible scholarly merit. Some problems with radiocarbon dates are also considered.
متن کاملA calibrated chronology of biochemistry reveals a stem line of descent responsible for planetary biodiversity
Time-calibrated phylogenomic trees of protein domain structure produce powerful chronologies describing the evolution of biochemistry and life. These timetrees are built from a genomic census of millions of encoded proteins using models of nested accumulation of molecules in evolving proteomes. Here we show that a primordial stem line of descent, a propagating series of pluripotent cellular ent...
متن کاملDistributed Planetary Object Name Service: Issues and Design Principles
The ONS is a central lookup service used in the EPCglobal network for retrieving the location of information about a specific EPC. This centralized solution lacks scalability and fault tolerance. We present the design principles of a distributed solution for ONS lookup service. In distributed systems, the problem of providing a scalable location service requires a dynamic mechanism to associate...

متن کاملChronology Protection in String Theory
Many solutions of General Relativity appear to allow the possibility of time travel. This was initially a fascinating discovery, but geometries of this type violate causality, a basic physical law that is believed to be fundamental. Although string theory is a proposed fundamental theory of quantum gravity, geometries with closed timelike curves have resurfaced as solutions to its low energy eq...
