Quantum: Einstein, Bohr And The Great Debate About The Nature Of Reality

'This is about gob-smacking science at the far end of reason … Take it nice and easy and savour the experience of your mind being blown without recourse to hallucinogens' Nicholas Lezard, Guardian 
For most people, quantum theory is a byword for mysterious, impenetrable science. And yet for many years it was equally baffling for scientists themselves.

In this magisterial book, Manjit Kumar gives a dramatic and superbly-written history of this fundamental scientific revolution, and the divisive debate at its core. Quantum theory looks at the very building blocks of our world, the particles and processes without which it could not exist.

Yet for 60 years most physicists believed that quantum theory denied the very existence of reality itself. In this tour de force of science history, Manjit Kumar shows how the golden age of physics ignited the greatest intellectual debate of the twentieth century.

Quantum theory is weird. In 1905, Albert Einstein suggested that light was a particle, not a wave, defying a century of experiments. Werner Heisenberg's uncertainty principle and Erwin Schrodinger's famous dead-and-alive cat are similarly strange. As Niels Bohr said, if you weren't shocked by quantum theory, you didn't really understand it.

While 'Quantum' sets the science in the context of the great upheavals of the modern age, Kumar's centrepiece is the conflict between Einstein and Bohr over the nature of reality and the soul of science. 'Bohr brainwashed a whole generation of physicists into believing that the problem had been solved', lamented the Nobel Prize-winning physicist Murray Gell-Mann. But in 'Quantum', Kumar brings Einstein back to the centre of the quantum debate. 'Quantum' is the essential read for anyone fascinated by this complex and thrilling story and by the band of brilliant men at its heart.

auto-rolling dog ball
I don't know what i'm doing wrong but my pets don't enjoy it. It's mobile on both settings. I think it just needs a place inside to place a treat or something. Quality seems okay. The battery lasts a long time. They chewed on it for a little bit and left it, the material is okay. It's made of some kind of rubber.

Fun, Interactive Toy That Keeps Pets Engaged
Summary: A smart rolling dog toy that helps reduce boredom and keeps pets active with minimal effort. Pros: Auto-rolling feature keeps play engaging Durable, chew-resistant design Encourages activity and mental stimulation Simple to use with minimal setup Works well for solo play sessions Cons: May be noisy on hard floors Not ideal for very aggressive chewers Battery life could be longer Movement pattern can feel repetitive Overall review: This interactive dog ball is a great option for keeping pets entertained, especially when they need something to do on their own. The auto-rolling feature is the main highlight—it moves unpredictably enough to grab attention and keep dogs engaged for longer than a standard toy. It’s especially useful for reducing boredom when you’re busy or not able to actively play. The build feels fairly durable and holds up well for regular chewing, though it’s probably not meant for extremely aggressive chewers. On hard floors, it can be a bit noisy as it moves around, and over time, the movement patterns may start to feel repetitive to more curious dogs. Still, it does what it’s designed to do—encourage activity and provide stimulation. Overall, it’s a fun and practical toy that adds some variety to a dog’s play routine.

Fun for an active dog!
I have an Australian Shepherd that absolutely loves this auto rolling dog ball! The ball is hard, but covered in a rubber coating. It is still loud when it hits the floor, but that is to be expected. My dog has chased this as well as thrown this ball, and it is still working flawlessly! This ball is definitely durable! It is easy to charge, and provides hours of entertainment! The ball is a great size for a medium dog. I recommend it!

Auto-Rolling Dog Ball - loud with a mystery filling.
I got this to entertain my high energy dog and she does like it, but I don't. The ball is incredibly loud and doesn't move around nearly as much as I had hoped. When your dog picks it up, it turn their mouth into an amplifier making it louder. It bounces/vibrates around more than rolling. Which is not what I expected, but seems to be engaging enough for more dog (but that doesnt take much). What I really dislike is there is no way on the exterior to know what mode you are in and the inside is full of grease. To charge it and to see the lights to identify what mode it is involves opening it and touching the grease covered insides. The lights don't seem to match the instructions when trying to switch modes. The light is supposed to stay on for 3s. It doesn't for either mode and immediately cycles through other colors making it more confusing. The exterior seems durable enough for a moderate chewer and I like the color and texture. At $15, it seems like a fair price, but I can't recommend this at any price point. I don't feel comfortable letting my dogs play with toys that could easily expose them to an unidentified grease. Any greased components should be sealed. Not somewhere I have to touch for normal operation and potentially leak.

Gentle vibrations and rolling
My sweet old man dog didnt know what to think of this at first. We introduced it to him without turning it on at first, like a regular ball. That was fine, he was good with that and he liked to go chasing it (its heavy because its mechanical so I wouldnt throw it, a light toss/roll is how we started). After we played that way a while we turned it on. At first he was confused as to why his toy was chasing him. It mostly vibrates and bops around a bit. But then my pup started chasing it and kicking it around like a little soccer ball and he LOVED THAT. A charge lasts quite a while too and if he doesnt play with it in for a few minutes it goes to sleep so its not just bouncing constantly and driving me crazy. My pup likes it and it gives me a rest from the constant throwing so I'm happy!
