In this funny comic, we join Bob and his dog Rick on an entertaining journey into the world of quantum physics and its mysteries. Quantum physics surrounds us constantly, whether in the vast infinity or in our immediate vicinity. However, what it tells us about the world is completely different from what we see or feel, challenging our imagination. How can a cat be both alive and dead at the same time? The great physicists and pioneers of quantum physics guide Bob and his dog through the problems they tackle and their solutions: Planck, Einstein, Heisenberg, Schrödinger, Bohr, Born, Everett. A thrilling journey through a multitude of possible worlds begins! The simple drawings by Mathieu Burniat emphasize the clear and humorous explanation of quantum theory by Thibault Damour, who is also a professor.
