泡沫物理学史拾萃

人们对泡沫习以为常,却很难理解它的奇特性质,比如几乎完全由空气组成的泡沫,既能像固体一样发生弹性形变,又能像流体一样发生流动,这正是泡沫物理学的研究内容之一.泡沫物理是一门古老的学科,早在19世纪中下叶,气泡和泡沫结构静力学的描述已经完美,之后没有大的发展,直到1990年前后,随着流体力学、微观显像技术和计算技术等学科的发展,以及受材料科学和工业生产的需求,泡沫物理研究再次活跃起来.文章第一作者曾跟随英国皇家学会院士Denis Weaire从事泡沫物理研究多年,在他的演讲和个人收藏中,文章作者积累了一些材料,在此基础上,又仔细查阅了相关文献,整理成此文,它基本概括了泡沫结构静力学发展历程中的重要事件.

A brief history of measurement

The aim of this paper is to situate the subject of measurement and metrology in its historical and philosophical context. Everyone agrees that the numeration of objects and the quantification of the characteristics of some simple systems are very ancient practices encountered in any specific civilisation. Indeed the link between measurement and numeration comes from the beginnings. This is recalled here, as are the links between units and money, between references and authority. Then, the paper identifies and exhibits the different epistemological gaps occurred – or occurring – in the history of measurement in the western countries: geometry versus arithmetics, model versus experiment, prediction versus uncertainty, determinism versus quantum physics. Those gaps are described in relationship to the evolution of the internationally agreed system of units.     

A brief history of PEEM

The evolution of cathode lens-based photo emission electron microscopy (PEEM) from the simple beginnings in the early 1930s to its sophisticated present state is discussed. In addition to conventional ultraviolet light-excited PEEM (UV-PEEM), laser excited PEEM and the various modes of synchrotron X-ray-excited PEEM (XPEEM) particular emphasis is placed on the complementary combination of these methods with low energy electron microscopy (LEEM).

A brief history of gravitational wave research

For the benefit of the readers of this journal, the editors requested that we prepare a brief review of the history of the development of the theory, the experimental attempts to detect them, and the recent direct observations of gravitational waves (GWs). The theoretical ideas and disputes beginning with Einstein in 1916 regarding the existence and nature of gravitational waves and the extent to which one can rely on the electromagnetic analogy, especially the controversies regarding the quadrupole formula and whether gravitational waves carry energy, are discussed. The theoretical conclusions eventually received strong observational support from the binary pulsar. This provided compelling, although indirect, evidence for gravitational waves carrying away energy—as predicted by the quadrupole formula. On the direct detection experimental side, Joseph Weber started more than fifty years ago. In 1966, his bar for GW detection reached a strain sensitivity of a few times ${10}^{?16}$. His announcement of coincident signals (now considered spurious), stimulated many experimental efforts from room temperature resonant masses to cryogenic detectors and laser-interferometers. Now there are km-sized interferometric detectors (LIGO Hanford, LIGO Livingston, Virgo and KAGRA). Advanced LIGO first reached a strain sensitivity of the order of ${10}^{?22}$. During their first 130 days of observation (O1 run), with the aid of templates generated by numerical relativity, they did make the first detections: two 5-σ GW events and one likely event. Besides earth-based GW detectors, the drag-free sensitivity of the LISA Pathfinder has already reached to the LISA goal level, paving the road for space GW detectors. Over the whole GW spectrum (from aHz to THz) there are efforts for detection, notably the very-low-frequency band (pulsar timing array [PTA], 300 pHz – 100 nHz) and the extremely-low (Hubble)-frequency (cosmic microwave background [CMB] experiment, 1 aHz – 10 fHz).

Colour and art: A brief history of pigments

Human beings have had an inherent urge to leave their mark in the form of works of art since prehistoric times. This has driven the quest for new and better pigments with which to make paints. This paper describes the origins and composition of earliest earth pigments used by primitive man to decorate the walls of caves through to the synthetic pigments developed in more recent times. Despite modern technology, the artist's palette remains a mixture of the pigments used by cave artists, natural pigments used in the middle ages, and modern organic compounds.

The current status of research in ultrahigh-energy cosmic ray physics: A brief review

The origin and nature of ultrahigh-energy cosmic rays (UHECRs, E > 10¹⁸ eV) is one of the most intriguing unsolved problems of modern astrophysics. This review is dedicated to the current status of research in this field. We describe the largest ongoing experiments carried out at the Pierre Auger Observatory and Telescope Array, at the first orbital detector of UHECRs, that is, TUS, and for the KLPVE and JEM-EUSO orbital telescopes, which are currently being developed. We discuss the latest results on the energy spectrum and mass composition of UHECRs and the relationship between UHECRs on the one hand and ultrahigh-energy neutrinos and photons on the other. Finally, we review the latest results on the anisotropy of the arrival directions of UHECRs, which is a crucially important area of research in the search for astrophysical sources of cosmic rays in the highest energy range.
