Frank X. Gaspar’s collection of poems is haunted by the presence of mystics and visionaries: Mohammed, Buddha, St. Paul, Augustine, George Herbert, Emily Dickinson, Blake, Milton, Rilke. A Field Guide to the Heavens is punctuated with designs of science, the wondering and rapt observations of the sky made at the eyepiece of a backyard telescope. We come to know Gaspar’s city streets, the neighbors and strangers that walk them, the wreckage of past lives, the ocean, the gardens, the orchards and alleys and parking lots, all spread out under the vast sky.

The award-winning former editor of Science News shows that one of the most fascinating and controversial ideas in contemporary cosmology—the existence of multiple parallel universes—has a long and divisive history that continues to this day.
We often consider the universe to encompass everything that exists, but some scientists have come to believe that the vast, expanding universe we inhabit may be just one of many. The totality of those parallel universes, still for some the stuff of science fiction, has come to be known as the multiverse.
The concept of the multiverse, exotic as it may be, isn’t actually new. In The Number of the Heavens, veteran science journalist Tom Siegfried traces the history of this controversial idea from antiquity to the present. Ancient Greek philosophers first raised the possibility of multiple universes, but Aristotle insisted on one and only one cosmos. Then in 1277 the bishop of Paris declared it heresy to teach that God could not create as many universes as he pleased, unleashing fervent philosophical debate about whether there might exist a “plurality of worlds.”
As the Middle Ages gave way to the Renaissance, the philosophical debates became more scientific. René Descartes declared “the number of the heavens” to be indefinitely large, and as notions of the known universe expanded from our solar system to our galaxy, the debate about its multiplicity was repeatedly recast. In the 1980s, new theories about the big bang reignited interest in the multiverse. Today the controversy continues, as cosmologists and physicists explore the possibility of many big bangs, extra dimensions of space, and a set of branching, parallel universes. This engrossing story offers deep lessons about the nature of science and the quest to understand the universe.
Peripatetic cosmology.
Aristotle, great Greek philosopher, researcher, reasoner, and writer, born at Stagirus in 384 BC, was the son of a physician. He studied under Plato at Athens and taught there (367–347); subsequently he spent three years at the court of a former pupil in Asia Minor. After some time at Mitylene, in 343–342 he was appointed by King Philip of Macedon to be tutor of his teen-aged son Alexander. After Philip’s death in 336, Aristotle became head of his own school (of “Peripatetics”), the Lyceum at Athens. Because of anti-Macedonian feeling there after Alexander’s death in 323, he withdrew to Chalcis in Euboea, where he died in 322.
Nearly all the works Aristotle prepared for publication are lost; the priceless ones extant are lecture-materials, notes, and memoranda (some are spurious). They can be categorized as follows:
I Practical: Nicomachean Ethics; Great Ethics (Magna Moralia); Eudemian Ethics; Politics; Economics (on the good of the family); On Virtues and Vices.
II Logical: Categories; Analytics (Prior and Posterior); Interpretation; Refutations used by Sophists; Topica.
III Physical: Twenty-six works (some suspect) including astronomy, generation and destruction, the senses, memory, sleep, dreams, life, facts about animals, etc.
IV Metaphysics: on being as being.
V Art: Rhetoric and Poetics.
VI Other works including the Constitution of Athens; more works also of doubtful authorship.
VII Fragments of various works such as dialogues on philosophy and literature; and of treatises on rhetoric, politics, and metaphysics.
The Loeb Classical Library edition of Aristotle is in twenty-three volumes.
