A Palette of Particles
Jeremy Bernstein
Harvard University Press, 2013

From molecules to stars, much of the cosmic canvas can be painted in brushstrokes of primary color: the protons, neutrons, and electrons we know so well. But for meticulous detail, we have to dip into exotic hues—leptons, mesons, hadrons, quarks. Bringing particle physics to life as few authors can, Jeremy Bernstein here unveils nature in all its subatomic splendor.

In this graceful account, Bernstein guides us through high-energy physics from the early twentieth century to the present, including such highlights as the newly discovered Higgs boson. Beginning with Ernest Rutherford’s 1911 explanation of the nucleus, a model of atomic structure emerged that sufficed until the 1930s, when new particles began to be theorized and experimentally confirmed. In the postwar period, the subatomic world exploded in a blaze of unexpected findings leading to the theory of the quark, in all its strange and charmed variations. An eyewitness to developments at Harvard University and the Institute for Advanced Study in Princeton, Bernstein laces his story with piquant anecdotes of such luminaries as Wolfgang Pauli, Murray Gell-Mann, and Sheldon Glashow.

Surveying the dizzying landscape of contemporary physics, Bernstein remains optimistic about our ability to comprehend the secrets of the cosmos—even as its mysteries deepen. We now know that over eighty percent of the universe consists of matter we have never identified or detected. A Palette of Particles draws readers into the excitement of a field where the more we discover, the less we seem to know.

Particles in Ancient Greek Discourse
Exploring Particle Use across Genres
Anna Bonifazi
Harvard University Press

The study of ancient Greek particles has been an integral part of the study of the Greek language from its earliest beginnings. Among the first parts of speech to be distinguished in Greek scholarship were the σύνδεσμοι (“combiners”), which include the later category of particles. In the Renaissance, Matthaeus Devarius—a Greek scholar working in Rome—published a monograph on particles only sixteen years after Estienne’s Thesaurus Linguae Graecae, and in the nineteenth century many great German philologists devoted considerable attention to particles and their forms, functions, and meanings. In the second half of the twentieth century Greek particles have returned to scholarly attention, partly as a result of the developments in contemporary linguistics.

The Emmy-Noether project “The Pragmatic Functions and Meanings of Ancient Greek Particles,” carried out in the Classics Department of the University of Heidelberg from 2010 to 2014, set out to trace more than two millennia of research on Greek particles, and to take stock of current work on particles, both within and beyond ancient Greek. Building on the foundations of this scholarship, Particles in Ancient Greek Discourse undertakes an analysis of particle use across five genres of ancient Greek discourse: epic, lyric, tragedy, comedy, and historiography.

Particles in Our Air
Exposures and Health Effects
John Daniel Spengler
Harvard University Press, 1996
It is no secret that the burning of fossil fuels causes air pollution and adversely affects the health of the human population. Over the last 10 years, research has been providing new insight about the health consequences of particulate air pollution. Generated by the use of fossil energy, respirable-sized particles pose a major threat to our environment and health. In this book the hypothesis that fossil fuels are the primary culprit is examined in detail, including the nature, generation, and transport of particulate air pollution. The authors cite studies on animals and epidemiological studies—those showing acute effects soon after exposure and those exhibiting chronic effects decades later—and include models describing mechanisms by which the effects of fine particulates can be induced. Through its probing inquiry, this book makes clear that present levels of air pollution, even in countries with aggressive environmental controls, are a health hazard that must be contended with.

A Thin Cosmic Rain
Particles from Outer Space
Michael W. Friedlander
Harvard University Press, 2000

Enigmatic for many years, cosmic rays are now known to be not rays at all, but particles, the nuclei of atoms, raining down continually on the earth, where they can be detected throughout the atmosphere and sometimes even thousands of feet underground. This book tells the long-running detective story behind the discovery and study of cosmic rays, a story that stretches from the early days of subatomic particle physics in the 1890s to the frontiers of high-energy astrophysics today.

Writing for the amateur scientist and the educated general reader, Michael Friedlander, a cosmic ray researcher, relates the history of cosmic ray science from its accidental discovery to its present status. He explains how cosmic rays are identified and how their energies are measured, then surveys current knowledge and theories of thin cosmic rain. The most thorough, up-to-date, and readable account of these intriguing phenomena, his book makes us party to the search into the nature, behavior, and origins of cosmic rays—and into the sources of their enormous energy, sometimes hundreds of millions times greater than the energy achievable in the most powerful earthbound particle accelerators. As this search led unexpectedly to the discovery of new particles such as the muon, pion, kaon, and hyperon, and as it reveals scenes of awesome violence in the cosmos and offers clues about black holes, supernovas, neutron stars, quasars, and neutrinos, we see clearly why cosmic rays remain central to an astonishingly diverse range of research studies on scales infinitesimally small and large.

Attractively illustrated, engagingly written, this is a fascinating inside look at a science at the center of our understanding of our universe.
