I’ve long been a fan of DK’s non-fiction books, which are mostly aimed at young readers but are also a great resource for adults as starter points or refreshers. That holds true for one of their newest offerings with the somewhat oxymoronic title Simply Quantum Physics.
The book is separated into several sections:
• “The Quantum World”: basic information on particles and forces
• “Pre-Quantum Puzzles”: early physics problems solved by quantum physics
• “The Wave Function”: unsurprisingly, an explanation of wave functions
• “Interpretations of Quantum Physics”: various theories behind the weird results of quantum experiments
• “Quantum Phenomena”: basic behaviors in the quantum world such as tunneling, exclusion, etc.
• “Quantum Technology”: application of quantum theory/behavior
• “Quantum Information”: quantum computing
• “Nuclear Physics”: how fission and fusion work
• “Particle Physics”: a deeper dive into the particles theorized in the Standard Model and Field Theory
• Quantum Gravity: attempts to end the conflicts between quantum theory and relativity (gravity)
• Quantum Biology: a relative new field exploring quantum physics in the realm of the living
This is one of the most difficult topics to simplify, but DK does as good a job as possible I’d say. This is not, though, for kids, as the terminology assumes some basic scientific knowledge and vocabulary. Basic, but still some. The text is always lucid and concise. DK always makes excellent use of visuals, and this book is another example of their strength in this area. Especially in this realm, visuals go a long way toward making things much more comprehensible, and nearly ever section is greatly enhanced by the visuals employed. The text is also nicely up to date, including discussion of the Higgs Boson and gravitons (though not the recent discovery of gravity waves). If I had to offer a minor suggestion for how it could have been improved, it might have been more liberal use of metaphors, which often help make the near-incomprehensible more understandable. Otherwise, this is yet another excellent entry in DK’s long list of stellar non-fiction works (I plan on sending it to my college son not so much for learning physics – he is taking a class after all—but so he can have an easy to grab, easy to visualize refresher of his more complex coursework.
