متن کاملPerception of music performance on historical and modern commercial recordings.
Performing styles as well as recording styles have changed considerably within the 20th century. To what extent do the age of a recording, the unfamiliarity with performing style, and the quality of a reproduction of a recording systematically influence how we perceive performances on record?

Plant cytogenetics has continued to flourish and make essential contributions to genomics projects by delineating marker order, defining contig gaps and revealing genome rearrangements. Here we review the field of plant cytogenetics from its conception through the eras of molecular biology and genomics. Significant advances in chromosome preparation, such as extended fiber-FISH, have greatly in...
متن کاملAn Historical and Modern View on Bell’s Inequality
After a general introduction, we introduce the reader to some subtleties of quantum mechanics from an historical perspective. We discuss the famous EPR paper, in which Einstein, Podolsky, and Rosen claim that either we live in a world with ‘spooky actions at a distance’ or quantum mechanics is incomplete. After discussing various completeness ‘proofs’, a lot of attention will be paid to Bell’s ...
متن کاملFrom Historical Perspectives to Some Modern Possibilities
A historical perspective on the study of asymmetries in planetary nebulae (PNs) is presented. We also describe our ongoing work in high resolution spectroscopy of planetaries, and discuss some likely future directions for the study of asymmetrical PNs. The first systematic study of planetary nebulae (PNs) was undertaken at Lick Observatory from 1914 to 1917 and is reported in detail in Volume 1...
