12 . the Magnetostratigraphy of Leg 94 Sediments
The primary objective of DSDP Leg 94 was to obtain continuous paleoclimatic records along a roughly north-south transect in the North Atlantic. The magnetostratigraphy of 21 holes at 6 sites cored with the hydraulic piston corer and extended-core-barrel corer is presented here and establishes an independent chronology for these sediments. Nearly complete records were obtained for the last 2.5 m...

متن کاملRadiometric Clocks
Introduction In the present nuclear age, the devastating effects of radioactivity have been highlighted by such issues as nuclear weapons testing and radioactive waste disposal, and by the reactor incidents at Three Mile Island and Chernobyl. These events illustrate the vexing problems that can be associated with high levels of radioactivity. However, the presence of radioactivity is not limite...
متن کاملCosmic strings and chronology protection.
A space consisting of two rapidly moving cosmic strings has recently been constructed by Gott that contains closed timelike curves. The global structure of this space is analysed and is found that, away from the strings, the space is identical to a generalised Misner space. The vacuum expectation value of the energy momentum tensor for a conformally coupled scalar field is calculated on this ge...
متن کاملQuantized Fields and Chronology Protection
Several recent possible counterexamples to the Chronology Protection Conjecture are critically examined. The “adapted” Rindler vacuum state constructed by Li and Gott for a conformal scalar field in Misner space is extended to nonconformally coupled and self-interacting scalar fields. For these fields, the vacuum stress-energy always diverges on the chronology horizons. The divergence of the va...
