Astrophysicist Gribbin (Erwin Schrodinger and the Quantum Revolution, 2013, etc.) clearly explains how the accidental discovery of "the cosmic microwave background radiation" in the mid-1960s led to the assignment of a definitive date for the origin of the universe.
Despite the fact that physicists have yet to unify quantum physics and relativity into one coherent theory, the author believes that the implications stemming from the discovery that the universe is 13.8 billion years old definitively proves the fundamental correctness of both. “The age of the Universe calculated by cosmologists…is just a tiny bit older than the age of the stars it contains," writes the author. The most profound of these is that our universe is not unchangeably "infinite in time and space." In the 1950s, astrophysicists were divided between those who believed in a steady-state universe (led by Albert Einstein) and proponents of the rival Big Bang theory. One way of resolving the dispute was to accurately determine the densities of galaxies in space. This allowed an inference to be drawn about their development over time. The placement of radio telescopes on satellites, which used photographic plates to build up images of the universe, made this possible. Analysis of the data lent credibility to the Big Bang theory, but it was the chance discovery of pervasive cosmic microwave radiation that decisively tipped the balance in its favor. The 1980s discovery of the existence of dark matter and energy (which exert a gravitational force but are impervious to radiation) has allowed scientists to recalculate the rate of expansion of the universe more precisely to fit the observed data. In order to bring lay readers up to speed, Gribbin first reprises the crucial developments, beginning in the 19th century, that have led scientists to their current understanding.

An alarming account of the “slow-motion catastrophe” facing the world’s largest freshwater system.
Based on 13 years of reporting for the Milwaukee Journal Sentinel, this exhaustively detailed examination of the Great Lakes reveals the extent to which this 94,000-square-mile natural resource has been exploited for two centuries. The main culprits have been “over-fishing, over-polluting, and over-prioritizing navigation,” writes Egan, winner of the J. Anthony Lukas Work-in-Progress Award. Combining scientific details, the stories of researchers investigating ecological crises, and interviews with people who live and work along the lakes, the author crafts an absorbing narrative of science and human folly. The St. Lawrence Seaway, a system of locks, canals, and channels leading to the Atlantic Ocean, which allows “noxious species” from foreign ports to enter the lakes through ballast water dumped by freighters, has been a central player. Biologically contaminated ballast water is “the worst kind of pollution,” writes Egan. “It breeds.” As a result, mussels and other invasive species have been devastating the ecosystem and traveling across the country to wreak harm in the West. At the same time, farm-fertilizer runoff has helped create “massive seasonal toxic algae blooms that are turning [Lake] Erie’s water into something that seems impossible for a sea of its size: poison.” The blooms contain “the seeds of a natural and public health disaster.” While lengthy and often highly technical, Egan’s sections on frustrating attempts to engineer the lakes by introducing predator fish species underscore the complexity of the challenge. The author also covers the threats posed by climate change and attempts by outsiders to divert lake waters for profit. He notes that the political will is lacking to reduce farm runoffs. The lakes could “heal on their own,” if protected from new invasions and if the fish and mussels already present “find a new ecological balance.”
Not light reading but essential for policymakers—and highly recommended for the 40 million people who rely on the Great Lakes for drinking water.Pub Date: March 7, 2017

BOOK REVIEW
It took 14 years to build and it cost 15 million dollars and the lives of 20 workmen. Like the Atlantic cable and the Suez Canal it was a gigantic embodiment in steel and concrete of the Age of Enterprise. McCullough's outsized biography of the bridge attempts to capture in one majestic sweep the full glory of the achievement but the story sags mightily in the middle. True, the Roeblings, father and son who served successively as Chief Engineer, are cast in a heroic mold. True, too, the vital statistics of the bridge are formidable. But despite diligent efforts by the author the details of the construction work — from sinking the caissons, to underground blasting, stringing of cables and pouring of cement — will crush the determination of all but the most indomitable reader. To make matters worse, McCullough dutifully struggles through the administrative history of the Brooklyn Bridge Company which financed and contracted for the project with the help of the Tweed Machine and various Brooklyn bosses who profited handsomely amid continuous allegations of kickbacks and mismanagement of funds. He succeeds in evoking the venality and crass materialism of the epoch but once again the details — like the 3,515 miles of steel wire in each cable — are tiresome and ultimately entangling. Workmanlike and thorough though it is, McCullough's history of the bridge has more bulk than stature.
