When is a cat both alive and dead at the same time?
Why, of course, when it comes to Schrödinger's cat. A cat with a dual nature.
The same happens with the atoms of the microcosm. They can be in two different places at the same time.
So, could it be that we - besides our usual familiar space - are also somewhere else at the same time?
Quantum physics raises extremely important philosophical and technological questions, which undoubtedly raise the pressure of thinkers.
The author - an excellent popularizer of science - detests strokes and states from the outset that the theory of quantum mechanics itself is neither strange nor irrational. On the contrary, it is a beautifully precise and logical mathematical construct that describes nature extremely well.
However, the great physicist Niels Bohr once said that "anyone who is not shocked by quantum mechanics has not understood it."
So, is quantum physics so incomprehensible? Is reality so strange? How can cats be both alive and dead at the same time?
What should we believe?
In a unique way, the book introduces us to the history of the theory and its modern practice. The quantum world hides bizarre concepts and strange stories, but on it is built the familiar world of our daily lives. Without quantum mechanics, we could not understand modern chemistry, electronics, or materials science. We would not have discovered the silicon chip or the laser, we would not have televisions, computers, microwave ovens, CD and DVD players, mobile phones, and so many other things that we take for granted in our technological age.
