Strange things! Vital quantum paradoxes, beyond the limits of understanding. Physicists and chemists are now accustomed to encountering Quantum Mechanics in their work, but biologists, until now, have not "bothered" with this strange yet powerful theory of the subatomic world. However, times are changing. Welcome to the realm of Quantum Biology! The "cunning" enzymes have never stopped using the quantum tunneling phenomenon for a moment, in order to accelerate the chemical reactions of life. The "smart" plants have never ceased to exploit quantum coherence, in order to supply their precious cells with life-giving light as efficiently as possible. Migratory birds, while flying, do not "turn off" quantum entanglement for even a second—the magical phenomenon that Einstein called "spooky action at a distance"—as they "pilot" carefreely within Earth's magnetic field. And the question arises relentlessly: How do the "fragile" phenomena of quantum mechanics—which until recently we thought were confined to the sterile laboratory environment, at temperatures close to absolute zero—manage to "survive" in our wet, warm, biological world?
