Quantum Theory: A Very Short Introduction

"Quantum Theory: A Very Short Introduction" explains how particles like electrons and photons behave in ways unlike everyday objects. At the quantum level, particles can exist in multiple states simultaneously (superposition) and influence each other instantly over distance (entanglement). These phenomena challenge classical physics and reveal a universe governed by probabilities rather than certainties. The book highlights how quantum mechanics underpins modern technology, like computers and medical imaging, and explores the ongoing quest to understand the fundamental nature of reality at the smallest scales, blending complex theory with accessible insights.
