A digestible, intriguing academic read on a complex subject.
A thorough delineation of neural representations, or brain maps, that affect our sensory, motor, cognitive, and emotional capacities.
Schwarzlose, a neuroscientist at Washington University in St. Louis, explores literal brain maps, within human and animal brains, comprised of cells. Unlike traditional geographical maps, they are dynamic by virtue of electricity and time. "Neighboring neurons in your brain represent neighboring plots of land on your skin,” she writes. “The result? A beautiful, honest-to-goodness map of the surfaces of your body built into your brain." The author uses the metaphor of subway tunnels in not only explaining how brain maps affect our sight and feeling, but also to demonstrate that a map's inherent two-dimensional distortion sometimes makes it better at magnifying important information. "Vision as you know it is born in the darkness at the back of your skull, reflecting what is happening in your visual brain maps more than what is happening in your two eyes,” she writes. “This is why it matters so much exactly how your maps are warped: these maps, in turn, warp your conscious perception." Schwarzlose illuminates four primary themes of brain maps: their universality, respective uniqueness, the idea that they are created out of necessity, and their ability to give organisms the opportunity to adapt. Not only are brain maps spatial, but they can also use nonspatial phenomena, such as vibrations, to reveal where a source of sound is located. Human brain maps were discovered in 19th-century London through experiments on patients who experienced seizures and the study of their paths. The parietal lobe, writes the author, holds maps that do not belong to a single category: “They actually combine and align information from touch, vision, and hearing with information about body position and space around the body to which actions might be guided." The scope of the book is staggering, as is the potential of technology's role in decoding minds, and yet Schwarzlose successfully and enthusiastically relays the research in relevant, understandable, and absorbing language. The black-and-white illustrations are also helpful.

A solid foundational education in a handful of lively scientific topics.
Two science podcasters answer their mail.
In this illustrated follow-up to We Have No Idea: A Guide to the Unknown Universe (2017), Cham, a cartoonist and former research associate and instructor at Caltech, and Whiteson, professor of physics and astronomy at the University of California, Irvine, explain the basic science behind subjects that seem to preoccupy the listeners of their podcast, Daniel and Jorge Explain the Universe. Most of the questions involve physics or astrophysics and take the form of, is such-and-such possible?—e.g., teleportation, alien visitors, building a warp drive, entering a black hole). The authors emphasize that they are answering as scientists, not engineers. “A physicist will say something is possible if they don’t know of a law of physics that prevents it.” Thus, a spaceship traveling fast enough to reach the nearest star in a reasonable amount of time is not forbidden by the laws of physics, but building one is inconceivable. Similarly, wormholes and time travel are “not known to be impossible”—as are many other scenarios. Some distressing events are guaranteed. An asteroid will strike the Earth, the sun will explode, and the human race will become extinct, but studies reveal that none are immediate threats. Sadly, making Mars as habitable as Earth is possible but only with improbably futuristic technology. For those who suspect that we are living in a computer simulation, the authors describe what clues to look for. Readers may worry that the authors step beyond their expertise when they include chapters on the existence of an afterlife or the question of free will. Sticking closely to hard science, they deliver a lucid overview of brain function and the debate over the existence of alternate universes that is unlikely to provoke controversy. The authors’ work fits neatly into the recently burgeoning market of breezy pop-science books full of jokes, asides, and cartoons that serve as introductions to concepts that require much further study to fully understand.

An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both...
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.
