Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments.

To fully experience the ecstatic poetry of the Middle and Near East, you must hear it as originally intended: stirred ablaze by inspired music and rhythms before a live audience. In I Want Burning, Coleman Barks fuses his passionate scholarship with a deep feeling for the poetry of Rumi, Hafiz (a 14th-century Sufi mystic, called "one of the jewels in the necklace of Persian poetry"), and Lalla (an exquisite Kashmiri female poet of the 14th century).

In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved.

Through Coleman Barks’s translations, Rumi is the world’s most popular poet. The newest addition to HarperSanFrancisco’s “A Year With” series, A Year with Rumi brings together 365 of Coleman’s mystical, elegant, and beautiful translations of Rumi’s poetry, for listening, reflection, and embarking upon your own journey inward.
