For some reason I'm always impressed when something both entertains me and educates me. It's as if all those years of torture schooling gave me unreasonable expectations.

But that is the case here. David Walton's Superposition is a fun romp through quantum physics. Jacob Kelly is a brilliant physicist who is confronted by an old friend who pretty much destroys his life.

His old friend has some secrets, mostly involving his scientific research and he arrives at Jacob's house, uninvited, and points

I admit, I have a love-hate relationship with hard sci-fi. To clarify, I am mostly talking about science fiction with heavy emphasis on science and technology. If an author can ease me gently into a story like this, it is certainly possible for me to become absorbed and enjoy myself. On the other hand, overwhelm me with techno-babble and science that I don’t understand, and you will see my eyes glazing over faster than a d

This was an entertaining courtroom drama that happened to geek out all over the place with a coherent explanation of quantum mechanics AND a relevant hard SF extrapolation of the theories.

What is that in laymen terms?

Murder mystery meets many-worlds.

I'm sure those people who geek out over courtroom dramas will get a lot more out of this novel than me. I would have been perfectly peachy with an action-science thriller, and I'll be frank, this novel would have met a five star for me if it had been

Honestly, this one borders on a 5 star read for me, but it lacks substance. Cool science though and one of the better fictionalizations of a lesson in quantum theory I've seen.

The story follows a particle physicist turned teacher who gets dramatically drawn back into his prior profession by a colleague's bizarre behavior. The book follows the colleague's visit and subsequent murder in one storyline and the trial of the main character for the colleague's murder in another alternating storyline. I

4 Stars - Had me hooked in right away. Felt like I came away some interesting knowledge that the author integrates almost too well into the plotline. Definitely a book that can spark some interesting conversations, loved it!

2.5 stars, barely, rounded down to two.

The quantum physics part of the story was very interesting, but the characters were very flat to me, very two-dimensional, almost like they were thrown in to show specific characteristics about the main character. For example, the wife and family seemed to be there only the show how good a husband/father he is. The (dumb) buddy is there to show how smart he is.

Aside from the mind-bending theoretical physics, this was all very pedestrian, and very disappoint

This was a really enjoyable quantum physics murder mystery. The science was explained in a readable way as part of the story. The courtroom parts were mostly accurate, which is fine because if there hadn't been any dramatic license taken it would have been deadly dull instead of page turning. Overall, a fast paced and exciting read.

I have never read anything by this author. Now that I have read this book, I plan to keep this author on my radar. OMG! I feel hard for this book. My only flaw was that I started it late in the evening and so I had to put it down to get some sleep. Yet, you can bet that once I got up and carved myself out some time, I jumped right back into this book. It was not long before I was finished with it.

This book may be fiction but it could read as if it was nonfiction. I could totally imagine this re

Quantum physics courtroom murder mystery all in one. I really enjoyed this book even if some of the science went over my head. I listened to the audio and the narrator did a good job with the pacing and maintaining the tension. Looking forward to the sequel.

Superposition by David Walton is a geeky physics based science fiction thriller that tickled my brain all the way down to my quarks, muons, toys, and neutrinos. Walton gets all the credit for making this novel work. It is not just for fans of hard science fiction or for people with a physics background. He tells this story to us in such a way that we are able to at least grasp upon the models portrayed. Walton uses the court case to further spell out the physics behind entanglement and

What would happen if the physics of the micro universe could be applied to the macro universe in which we live? It would be pretty weird as explained in this engaging story.

Einstein talked about the "spooky" aspect of quantum theory; things like, probability waves, particles being in two places at once, faster than light travel, all of these things seem possible on the subatomic level of reality but they are impossible in our universe...until now.

In the not so distant future, a scientist at the

Superposition is a book that dances between genres masterfully, injecting science fiction into mystery and legal dramas in a truly unique read. Fans of speculative fiction will be very pleased. At the center of the story is the question of what would happen if the things that are possible in the quantum world were possible in the physical world we observe? How does this affect our notions of humanity and existence? The author explains the quantum physics that drive the story in clear and concise ...more

I am not a science fiction fan. At all. But I devoured this compelling blend of science fiction, personal drama, and murder mystery in just a few evenings. A fun and very visual read--I could see the movie in my head as I read it.

Güzel roman, sonunu öğrenmek için sabahlayıp bitirdim kitabı. Kuantum fiziğine hiçbir aşinalığım yok, neyse ki gerizekalıya anlatır gibi anlatmış ne olduğunu. Görünüşe göre aynı anda iki farklı yerde bulunabiliyoruz. Bunu çok güzel kullanmış ve akıcı bir paralel kurguyla su gibi giden bir kitap yazmış yazarımız.

After reading numerous excellent reviews for Superposition and hearing excellent things about David Walton’s writing, I snapped up the chance to read and review Superposition when it was presented. I love science fiction. I love crime thrillers. So I’m willing to bet that I sure as hell am going to love a combination of the two. And Superposition really didn’t disappoint. This is a

Manchmal, ja, manchmal da komme ich mir dumm vor. Oder zumindest unwissend und uninformiert. Immer wenn ich Krimis lese, in denen sich die Handlung um politische oder geschichtliche Ereignisse dreht über die ich nichts oder fast nichts weiß, aber auch wenn über andere Länder oder Kulturen berichtet wird, die ich nicht kenne. Aber ich sehe das durchaus positiv – man kann schlicht und einfach nicht alles wissen und wie langweilige wäre es, wenn man schon alles wüsste? Ich lerne gerne aus Krimis. I ...more

You know how sometimes you take a chance on a book by an author you’ve never read before? That’s what I did with Superposition, and I couldn’t be happier! Walton delivers a spectacular genre mash up of science fiction, legal drama and murder mystery that will keep you thinking long after you’ve closed the book.

Superposition is about Jacob Kelley, a theoretical physicist, who is accused of murdering his old friend Brian, also a theoretical physicist. Brian was doing research that is the quantum physics equivalent of picking up the big Latin tome with Cthulhu on the cover, so naturally things got scary and he reached out to Jacob who, being a rational man, said something along the lines of, "I don't care what the voices in your head told you about your magic powers, stop pointing that gun at my wife!"

Wow. Superposition was an amazing science fiction thriller, courtroom drama, slight romance story, and so much more. I started the novel with a little hesitation, as it is a science fiction novel, and I usually read fantasy. I shouldn’t have hesitated. Superposition was an amazing read.

The novel contains two different story lines. The Up-Spin and the Down-Spin. Jacob Kelley, the protagonist, appears in both these story lines, but they are happening at the same time in different places. So how do

Going to rate this book based on three factors, then summarize.

As Courtroom Murder Mystery, it felt like Snow Falling on Cedars. Suspense was well maintained, with facts dolloped out as needed. There was even some intrigue from the police department side.

As Primer on Quantum Mechanics, this book works well. In the guise of explaining to the lawyer, jurors, and other non-scientific types, some good analogies are used and Quantum Physics gets a good break down.

As Thriller, this short novel is exce
From the structure of the book, with chapters alternating points of view from one version of the protagonist to another, to the ultimate reason that evil (?) is unleashed upon the world, Superposition keeps you thinking and guessing what is coming next. Like any story, there comes a point where you are pretty sure you know what is going to ultimately happen; David Walton does a very good job of putting this point as near to the end of the book as possible.

A bit of violence, a lot of discussion

Exciting storyline and great style of writing. Loved how quantum physics was incorporated into the book in layman terms. Couldn't wait to reconvene reading it each time I had a break. However, the ending was a bit too perfect and therefore unrealistic. But still definitely worth a read!

As I mentioned in my review of David Walton's latest novel, my copies of his quantum physics murder mysteries Superposition and Supersymmetry have been sitting on my "books to read" pile for a long, long time. I've always known that I'll get to them at some point, but there was always another novel/series that got in the way. But The Genius Plague was such a good read that I decided it was high time to read Walton's two science fiction technothrillers.

Person review
Superposition is a science fiction book that I personally enjoyed. It had the action and a sad storyline that matched each other well, and it has the action that I liked in a book. One thing that was intriguing that it was based around one science topic that scientist are talking about now. Another reason I liked this book I could relate to some characters in it.

It was early in the morning when Brian came over to Jacob’s house in shorts, a t-shirt, and sandals. Jacob let him in
