Introduction

E ver since the brilliant insights and accomplishments of Albert Einstein, Max Planck, Marie and Pierre Curie, Niels Bohr, Wolfgang Pauli, Enrico Fermi and their peers gained notoriety at the beginning of more than a century ago, the science of quantum physics has fascinated and tantalized a public hungry for knowledge, yet unable to decipher its mysteries and complexities.

As the first half of the 20th century unfolded, the discoveries of protons, neutrons, and electrons continued to evoke interest, which was further intensified when the atomic age began, demonstrating the awesome energy contained within the atom. Yet even today, many people envision a planetary model atom with a few satellite electrons orbiting close to a nucleus. Few can conceptualize a realistic image of an atom, or of its subatomic components, and how they interact with the governing forces that bind them. Are you wondering why theoretical physicists are fascinated by Schrdingers cat?

This book is written in simple English for those who are interested in learning about quantum physics, but dont want to get into the mathematics, the formulas, and the deep complexities. You may have heard of the theories of relativity and uncertainty, or of quarks, strings, and superstrings, the strong force and the weak force, and want to understand them. You may be aware of electromagnetic energy, but dont know how it fits into quantum physics. You want to know about the pioneering scientists who created quantum physics and nuclear energy, and would like their theories explained in a way that you can go, Aha, I get it now.

Rather than creating yet another textbook with chapter after chapter of ever-deepening details and with some formulas sneaking in, this book is in a format of 50 questions and their clear, brief answers. You can hop around to the questions that interest you most, but if you read it from beginning to end, youll appreciate how we go from the Big Bang theory of the creation of the universe, and then on to the smallest and newest subatomic particles.

I hope that your questions will be well-answered, and that your curiosity will be stimulated to look further and explore the issues within quantum physics that interest you most.

Q 1. What is quantum physics?

Quantum physics, also called quantum mechanics, is the branch of physics theory concerned with the smallest objects in the known universe, and includes atoms, the nucleus of the atom and its component protons and neutrons, the quarks within protons and neutrons, the electrons orbiting the nucleus, the particles and forces that hold the nucleus togetheror cause it to splitand all of the strange, irrational behaviors that these particles and forces exhibit.

The term quantum derives from the Latin quantus , meaning how much, and refers to Max Plancks concept that electromagnetic energy, including light, radio waves, electricity, and magnetism, radiates in discrete clusters, or quanta, and not as continuous physical fields or forces. The quantum particle that radiates light and other electromagnetic energies is called a photon.

Quantum physics begins at the atomic level, then drills down into the atoms components and the forces that influence them. We begin with the atom intact and first look at its components, and then the forces.

Q 2. Where did the universe come from, and where is it going?
