[I received a copy of this book through NetGalley, in exchange for an honest review.]

Not exactly easy to grasp—basic understanding of quantum physics (and some classical physics concepts, too) is definitely needed here—but the use of typical kitchen/breakfast examples helps when it comes to illustrating each point and show how deeply intertwined quantum physics is with what we take for granted in everyday life. There were more than just a couple things about which I had never really paid attention, and once the obvious was pointed at, it suddenly made a lot more sense.

I usually find Orzel’s writing pleasant enough to help me follow through physics explanations. I can’t say I’ve memorised every single thing in the book, obviously, however, my understanding is definitely better now.

If there’s one thing, I would say that the idea of drawing parallels with breakfast rituals, while interesting, was probably stretched out here, in that it was used at the beginning and very end of each chapter, but not really throughout. So even the comparisons were useful, this book has a more typical approach to physics than the author’s books where he has conversations with his dog.

Conclusion: With my limited but not completely ultra-basic understanding of the subject, I enjoyed this book a lot. This said, it would probably discourage complete beginners, at least partly.

Review: When the Uncertainty Principle Goes to 11

When the Uncertainty Principle Goes to 11: Or How to Explain Quantum Physics with Heavy MetalWhen the Uncertainty Principle Goes to 11: Or How to Explain Quantum Physics with Heavy Metal by Philip Moriarty

My rating: [rating=5]

Blurb:

There are deep and fascinating links between heavy metal and quantum physics. No, really!

While teaching at the University of Nottingham, physicist Philip Moriarty noticed something odd, a surprising number of his students were heavily into metal music. Colleagues, too: a Venn diagram of physicists and metal fans would show a shocking amount of overlap.

What’s more, it turns out that heavy metal music is uniquely well-suited to explaining quantum principles.

In When the Uncertainty Principle Goes to Eleven, Moriarty explains the mysteries of the universe’s inner workings via drum beats and feedback: You’ll discover how the Heisenberg uncertainty principle comes into play with every chugging guitar riff, what wave interference has to do with Iron Maiden, and why metalheads in mosh pits behave just like molecules in a gas.

If you’re a metal fan trying to grasp the complexities of quantum physics, a quantum physicist baffled by heavy metal, or just someone who’d like to know how the fundamental science underpinning our world connects to rock music, this book will take you, in the words of Pantera, to “A New Level.”

[I received a copy of this book through NetGalley, in exchange for an honest review.]

Why, oh, why did I take so much time to read this book? Well, alright, perhaps because I was busy reading other books to teach myself some physics principles, which, I admit, is never a bad thing when your physics classes go back to some, uhhhm, twenty years ago. At the very least.

I found this “metal + physics” approach to be a very intriguing and interesting one—all the more since the author injects a regular dose of humour into it, but never without a purpose (a.k.a. “how to discuss spatial periods using Stryper’s (in)famous striped pants as an example”). I suppose this approach may not work for everyone, but it definitely worked for me, probably because I never took myself too seriously even when dealing with serious things, because, after all, what does it matter, as long as we keep learning, right? Besides, it doesn’t harm when you can feel the passion shining through, and this was clearly the case here.

Overall, the topics broached here made a lot of sense. My own level in maths isn’t terrific, yet the author’s explanations were enough even for me to understand the principles and the equations he related to metal, harmonics, waves and strings, and so on. They don’t remain at such a basic level that they don’t bring much to one’s knowledge of physics (unless you’re already a post-graduate or someone working in that field already, in which case I suspect Fourier’s analysis of waves/patterns won’t seem such a wonder anymore—or will it?), and at the same time, they don’t stray into such abstractions that a beginner will completely lose their footing either. At any rate, I found it quite easy to picture phases when compared to a metalhead moving in a mosh pit…

Seriously, where was Professor Moriarty when I was studying physics at school? (Alright, alright, probably still doing his Ph. D., I guess.)

Review: The Quantum Labyrinth

The Quantum Labyrinth: How Richard Feynman and John Wheeler Revolutionized Time and Reality (The Theoretical Minimum)The Quantum Labyrinth: How Richard Feynman and John Wheeler Revolutionized Time and Reality by Paul Halpern

My rating: [rating=5]

Blurb:

The story of the unlikely friendship between the two physicists who fundamentally recast the notion of time and history
 
In 1939, Richard Feynman, a brilliant graduate of MIT, arrived in John Wheeler’s Princeton office to report for duty as his teaching assistant. A lifelong friendship and enormously productive collaboration was born, despite sharp differences in personality. The soft-spoken Wheeler, though conservative in appearance, was a raging nonconformist full of wild ideas about the universe. The boisterous Feynman was a cautious physicist who believed only what could be tested. Yet they were complementary spirits. Their collaboration led to a complete rethinking of the nature of time and reality. It enabled Feynman to show how quantum reality is a combination of alternative, contradictory possibilities, and inspired Wheeler to develop his landmark concept of wormholes, portals to the future and past. Together, Feynman and Wheeler made sure that quantum physics would never be the same again.

Review:

[I received a copy of this book through NetGalley, in exchange for an honest review.]

This is somewhat a strange book, hovering between a biography and physics book, through the lives of Richard Feynman and John Wheeler, and it seems to me it has both the good sides and shortcomings of both. Shortcomings, as in, it can’t go really in depth in the lives of the two scientists, and at the same time, the physics aspect is sometimes too complex, and sometimes too simple, which makes for an unbalanced read. But good sides, too, for linking the characters and their work, and giving an insight into said work, and overall making me want to read more about, well, everything in there. Probably in favour of Wheeler, since I already know quite a few things about Feynman (although I don’t seem to tire of him anyway).

I wouldn’t recommend it as a complete introduction to quantum and particle physics, though, since some of its contents are just too painful to follow without some basic knowledge of the topic.

I do recommend it for a global coverage of what Feynman and Wheeler worked on in their lifetime, to get pointers about specific topics worth researching more in depth later.

Style-wise, the book reads well enough in general, but more than once, some analogies were weird and fell flat for me.

Review: Lost In Math

Lost in Math: How Beauty Leads Physics AstrayLost in Math: How Beauty Leads Physics Astray by Sabine Hossenfelder

My rating: [rating=4]

Blurb:

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates trusted theories from disposable ones. This is why, Sabine Hossenfelder argues, physics hasn’t made a major breakthrough in more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or string theory, invented by physicists based on aesthetic criteria. Worse, these “too good to not be true” theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink how they do physics. Only by embracing messiness and complexity can science discover the truth, not as one might prefer it, but as it is.

Review:

[I received a copy of this book from NetGalley.]

I can’t say for sure that I understood everything in this book, since my knowledge of physics in general is very patchy, but overall, I liked its tone, and its global idea, because I can get why one would be easily led astray by theories that look ‘beautiful’. It’s something that I feel is very human, after all, as we often look for a form of harmony in the world surrounding us, if only to try and make sense of it. Perhaps the fundamental, underlying laws of nature don’t make that much sense, or don’t always look like they do, and so we try to understand them in ways that would reconcile us with an apparent lack of… meaning, maybe? But what if the theories we pursue, albeit ‘pretty’ and nicely wrapped, turn out to be wrong? Shall we keep pursuing those, in the hopes that we just haven’t seen proof yet due to technological limitations, for instance? It seems that the answer to this isn’t so clear-cut. (The LHC being a good example. I’m tremendously excited by the LHC, and what it allowed to prove so far… but while we got the Higgs boson, we still haven’t gotten supersymmetry.)

The book also gave me pointers about things of which I clearly don’t know enough, especially in order to understand where the author comes from, so I know I’ll have to focus on those at some point in order to learn more.

As a side note, I don’t know, but I don’t feel particularly bothered by the ‘ugliness’ of the Standard Model. It may be in part because all I know about it, I learnt on my own, without following the regular cursus, so I never approached it with any specific idea in mind? We’ll see once I’ve studied more.

Conclusion: Definitely interesting, although don’t approach it if you know next to nothing to physics, since some ideas won’t make sense otherwise.
