It presents a detailed derivation of the Feynman diagram technique and discusses the method of functional integrals in
quantum theory. There is special attention to the connections between quantum field theory and modern condensed matter theory.
However,
quantum theory predicts that the particles, once they have interacted, somehow remain linked to each other, despite being physically apart.
Maudlin argues that the very term "
quantum theory" is a misnomer.
"Yet if as I hope, basic science becomes part of general awareness, what now appear as a paradox of
quantum theory will seem as just common sense to our children's children." Hawking was proud that the book contained only one math equation: Relativity's famous E=MC squared.
So despite the fact that entanglement goes against classical intuition, entanglement must be an inevitable feature of not only
quantum theory but also any non-classical theory, even those that are yet to be developed.
In chapter 2, "Faith, an Overview of
Quantum Theory," Penrose begins to point out where he believes the problem lies.
Quantum theory is about nature at its smallest scale and energy levels and describes the behaviour of sub-atomic particles like electrons, protons, neutrons and photons.
After a century,
Quantum Theory remains an enigma: a uniquely successful predictive formalism in search of an intuitively clear, comprehensible, logically sound and self-consistent interpretation, with a concomitant philosophy and worldview--a quantum paradigm.
Chapters discuss the many inventions that have stemmed from
quantum theory, survey the science behind these discoveries, and reveal how scientists and researchers apply quantum mechanics to new discoveries, making this a lively, accessible title not just to science readers, but for general-interest individuals.
Max Planck--founder of the
quantum theory of thermal radiation.
Quantum theory explains how matter acts at the tiniest levels; in applying it to computing, researchers study ways in which that behavior can advance processing power.
