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.

by Lulu Miller illustrated by Kate Samworth ‧ RELEASE DATE: April 14, 2020
A quirky wonder of a book.
A Peabody Award–winning NPR science reporter chronicles the life of a turn-of-the-century scientist and how her quest led to significant revelations about the meaning of order, chaos, and her own existence.
Miller began doing research on David Starr Jordan (1851-1931) to understand how he had managed to carry on after the 1906 San Francisco earthquake destroyed his work. A taxonomist who is credited with discovering “a full fifth of fish known to man in his day,” Jordan had amassed an unparalleled collection of ichthyological specimens. Gathering up all the fish he could save, Jordan sewed the nameplates that had been on the destroyed jars directly onto the fish. His perseverance intrigued the author, who also discusses the struggles she underwent after her affair with a woman ended a heterosexual relationship. Born into an upstate New York farm family, Jordan attended Cornell and then became an itinerant scholar and field researcher until he landed at Indiana University, where his first ichthyological collection was destroyed by lightning. In between this catastrophe and others involving family members’ deaths, he reconstructed his collection. Later, he was appointed as the founding president of Stanford, where he evolved into a Machiavellian figure who trampled on colleagues and sang the praises of eugenics. Miller concludes that Jordan displayed the characteristics of someone who relied on “positive illusions” to rebound from disaster and that his stand on eugenics came from a belief in “a divine hierarchy from bacteria to humans that point[ed]…toward better.” Considering recent research that negates biological hierarchies, the author then suggests that Jordan’s beloved taxonomic category—fish—does not exist. Part biography, part science report, and part meditation on how the chaos that caused Miller’s existential misery could also bring self-acceptance and a loving wife, this unique book is an ingenious celebration of diversity and the mysterious order that underlies all existence.

Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.
