摘要:

All the world has been hoping for evidence that Martin Fleischmann of the University of Southampton, England, and Stanley Pons of the University of Utah are right. The pair claimed on 23 March that, inside a small cell containing a palladium cathode immersed in heavy water at room temperature, deuterium nuclei were fusing and producing heat at a rate four times higher than the input power. Two hectic months later scores of research groups were ready to confirm or deny that claim. Many reported at special sessions of the APS meeting in Baltimore and of the Electrochemical Society meeting in Los Angeles in early May. At the time of this writing the “nays” were outnumbering the “yeas.” Although the final tally will not be taken until more experiments are done and all papers are published in peer‐reviewed journals, the euphoria is quickly fading.

摘要:

Knowledge of the structures of macromolecules is of major importance both to basic science and to new, burgeoning industries. The determination of these structures is improving our understanding of fundamental biological processes, and so it sets the stage for the broad explanation of diseases on the molecular level and for the rational design of drugs. It promises to give insight into such topics as the mechanisms of enzyme action, the implications of protein structure for evolutionary development, the relation of amino acid sequences to three‐dimensional structure and the relation between structure and function in complicated systems such as viruses, muscle, ribosomes and chromatin.

摘要:

Mass is one of the most fundamental concepts of physics. Understanding and calculating the masses of the elementary particles is the central problem of modern physics, and is intimately connected with other fundamental problems such as the origin ofCPviolation, the mystery of the energy scales that determine the properties of the weak and gravitational interactions, the compositeness of particles, supersymmetry theory and the properties of the not‐yet‐discovered Higgs bosons.

摘要:

ANew York Timesarticle by Edwin McDowell on 2 February 1989 was headlined “Top Books of 1988: Spies and Physics.” Did he say physics? Yes. Best‐seller lists in 1988 included Stephen Hawking'sA Brief History of Timeand James Gleick'sChaos: Making a New Science. Two books by Richard Feynman were selling well—Surely You're Joking, Mr. FeynmanandWhat DoYouCare What Other People Think?And there were other notable physics and astronomy books as well, such as Michael Riordan'sThe Hunting of the Quarkand Richard Preston'sFirst Light, both winners of AIP Science Writing Prizes.
