Of Time and Space and Other Things [17 Essays] Review

Of Time and Space and Other Things [17 Essays] review

This Of Time and Space and Other Things [17 Essays] review starts with the distinction that makes the book worth revisiting: Isaac Asimov is not trying to deliver a single grand theory of the universe. He is demonstrating how a scientifically trained mind can take an ordinary word, convention, or puzzle and patiently unfold the system hidden inside it. A calendar becomes an argument about astronomy and social compromise. The names of planets become a lesson in language and classification. Zero, gravity, planetary rotation, and the speed of light become invitations to reason from familiar things toward less intuitive scales.

That method is the collection's real subject. First published in 1965, the book gathers seventeen pieces, most of them originally written during a concentrated run of Asimov's science columns for The Magazine of Fantasy and Science Fiction. Their fields vary widely, but their intellectual motion is consistent: begin with a question that sounds almost playful, establish a few definitions, and then build outward step by step. The result is a lively example of mid-twentieth-century popular science, with enough explanatory energy to survive the aging of some facts.

The central caution is equally important. This is not a substitute for a current astronomy or physics guide. It is best read as both science writing and a historical artifact: a record of what an unusually lucid explainer could do with the knowledge, terminology, and expectations of the early 1960s. Readers comfortable holding those two perspectives at once will find the book more rewarding than readers looking only for an up-to-date reference.

Seventeen columns, one recognizable method

The contents move through timekeeping, planetary science, cosmology, mathematics, chemistry, physics, and human aging. "The Days of Our Years" considers calendars; "Ghost Lines in the Sky" addresses latitude and longitude; "The Heavenly Zoo" turns to the zodiac; and "Roll Call" examines planetary nomenclature. Elsewhere, "Nothing Counts" approaches the discovery and importance of zero, while "Forget It!" looks at older systems of measurement. These are not chapters in a continuous textbook. They are compact excursions linked by Asimov's habit of finding an instructive problem inside a familiar convention.

The astronomical essays make that approach especially visible. "Just Mooning Around" considers satellites, and "Round and Round and..." deals with planetary rotation. "The Black of Night" takes up the expanding universe, while "A Galaxy at a Time" addresses galactic explosions. Each topic gives Asimov an opportunity to establish scale without abandoning the reader. Instead of asking for advanced preparation, he supplies a conceptual ladder and invites the audience to climb it.

That breadth makes the collection easy to sample. It also means momentum depends less on a cumulative argument than on the pleasure of watching the same explanatory instrument applied to different material. Readers who prefer tightly unified nonfiction may find the book scattered. Readers who like essays that can be read independently will see the variety as a strength.

What the strongest essays reveal

Asimov is most effective when the subject lets him expose a mismatch between common intuition and scientific description. Gravity feels dominant in ordinary life, yet "First and Rearmost" can reframe it as weak when compared with other fundamental interactions. Planetary motion seems simple until rotation, orbital relationships, and the pull between bodies complicate the picture. The symbols used in physics can look arbitrary until an essay such as "C for Celeritas" traces the question behind a familiar letter.

This is explanation through reorientation. Asimov does not merely hand over a conclusion; he rearranges the reader's starting assumptions. His transitions often move from words to quantities and from quantities to consequences. That sequence remains useful even when a particular numerical estimate or scientific expectation has been superseded, because it models how to ask what a term means, which comparison matters, and what follows from it.

The range also shows that scientific literacy is not confined to memorizing discoveries. "Welcome, Stranger!" concerns noble-gas compounds, "The Haste-Makers" concerns enzymes, and "A Piece of the Action" turns to Planck's constant. Together with essays on calendars and zero, these pieces present science as a network joined to history, naming, measurement, and changes in accepted possibility. The book's durable insight is that understanding often begins by noticing that a convention has a story.

"The Slowly Moving Finger," focused on aging, brings a more reflective tone than the collection usually sustains. A specialist retrospective of the book identifies it as an unusually personal and somber piece in Asimov's nonfiction. Its difference matters because it briefly tests the limits of the brisk explanatory voice: time is no longer only something to measure but also something human beings experience as loss and finitude.

Where the science shows its age

A sixty-year-old science collection inevitably contains more than period charm. Astronomy and cosmology have been transformed by later observations, space missions, instrumentation, and revised models. Planetary data that once invited informed speculation may now be treated with far stronger evidence. Terminology can also shift, and some confident explanatory shortcuts belong to a style of popular science less careful about foregrounding uncertainty than many contemporary readers expect.

The right response is not to treat every old detail as useless, nor to accept every statement without checking it. Separate the architecture of an explanation from the present status of its claims. Asimov's account of how to compare scales or unpack a convention can remain instructive even when a modern source should supply the final facts. That makes the book unusually suitable for paired reading: one can follow the reasoning, then ask what later evidence changed.

The collection also sometimes substitutes fluency for depth. A polished chain of examples can create the feeling that a field has been mastered when it has only been introduced. There are no sustained mathematical derivations, and the essay form leaves little room for competing interpretations or detailed evidence. This is an entry point, not a specialist treatment.

For current science organized around a larger cosmological argument, see our A Brief History of Time review. Readers should still approach that later classic critically, but the comparison clarifies what Asimov is and is not attempting here.

Style: clarity with a strong authorial presence

Asimov's prose is conversational, orderly, and openly delighted by intellectual puzzles. He often teaches by staging a small surprise: an everyday phrase proves imprecise, a familiar unit carries historical baggage, or an obvious ranking reverses when the basis of comparison changes. The humor is generally functional. It lowers the threshold of entry and gives the reader a reason to continue through material that might otherwise feel abstract.

The tradeoff is that the voice can dominate the subject. Readers who enjoy Asimov's genial certainty will find the essays fast and companionable. Those who prefer restrained, source-heavy science writing may find the performance too neat. The arguments tend to arrive already shaped for maximum intelligibility, with fewer visible detours, uncertainties, or methodological disputes than a modern critical account might include.

Even so, the clarity is not merely cosmetic. The book repeatedly demonstrates that technical explanation depends on sequence. A definition appears before a comparison; a comparison appears before a surprising implication. That craftsmanship helps explain why the collection remains readable after many of its scientific particulars have become historical.

Who should read it, and who should not

The ideal reader is curious, comfortable with essay collections, and willing to verify dated claims. No advanced scientific background is required. The pieces suit readers who enjoy learning why a familiar system works the way it does, as well as writers and teachers interested in how analogy, etymology, and scale can support explanation.

Asimov enthusiasts who know him chiefly through science fiction may be especially interested. The nonfiction reveals the same attraction to systems and consequences, but without plot or character carrying the argument. The imaginative act lies in choosing a perspective from which an established fact becomes surprising again.

The book is a weaker match for someone seeking a sequential introduction to one discipline, extensive documentation, or current consensus. Its variety prevents sustained development, and its age requires alert reading. A student can learn from it, but should not cite it as the last word on astronomy, cosmology, chemistry, or biology.

The broader science and nature collection offers more routes into these subjects. For a modern, wide-ranging book that leans into narrative history, our A Short History of Nearly Everything review explains a different kind of popular-science synthesis.

Context, alternatives, and the shape of popular science

The collection belongs to an era when the magazine essay was a major vehicle for bringing science to nonspecialists. Its seventeen pieces were not designed as a comprehensive curriculum; they emerged as recurring encounters with a recognizable guide. That origin explains both the book's appeal and its unevenness. A monthly column rewards novelty of entry point and a satisfying local conclusion, not necessarily the architecture of a single volume.

Readers wanting a more unified journey through cosmic scale should consider Carl Sagan's work; our Cosmos review discusses a book that binds astronomy to cultural history and humanity's place in the universe. Those who want a tighter focus on modern cosmological questions may prefer Stephen Hawking. Asimov's collection is better when the desired experience is episodic: seventeen chances to see an explanation assembled in public.

The comparison also highlights Asimov's special interest in the infrastructure of thought. Calendars, coordinates, names, symbols, and units can seem like preliminaries before the "real" science begins. In these essays, they are the real science because they determine what can be counted, compared, communicated, and imagined. The book is at its best when it makes those mental tools visible.

Final verdict

Of Time and Space and Other Things [17 Essays] is not the most coherent way to learn its many subjects, and it cannot bear the burden of being current. Its enduring value lies elsewhere: in the precision of its explanatory pacing, the variety of its questions, and its confidence that a lay reader can follow a difficult idea if each step is made legible.

Read selectively or straight through, the collection offers a compact education in popular-science technique. Its strongest essays turn ordinary language and everyday assumptions into doorways; its weaker pieces feel like preliminary versions of subjects Asimov handled elsewhere at greater length. Taken together, they show both the reach and the limits of his method. This is a worthwhile book for curious readers who want not just old scientific answers, but a vivid example of how those answers were once made intelligible.
