DANCE OF THE PHOTONS

FROM EINSTEIN TO QUANTUM TELEPORTATION

Not for the scientifically disinclined, but readers who pay close attention will grasp a strange but fascinating scientific...

A complex but ultimately rewarding exploration of the weird world of quantum physics, which describes the behavior of atomic and subatomic particles.

For example, light moves in both waves and particles, depending on the experiment. Quantum measurements can’t precisely locate a particle such as an electron, and a researcher can only give statistical odds that it’s in a particular spot (anywhere in the universe!). Einstein detested this idea, insisting that the description of light is wrong and that every electron is someplace. In his first book in English, Austrian physicist Zeilinger (Physics/Univ. of Vienna) defends the majority view: Quantum descriptions seem bizarre, but that’s the reality. Treading carefully, the author introduces two college freshmen, Bob and Alice, eager for a taste of quantum physics. Obligingly, their professor places each in distant rooms with a detector connected to a central source that emits light particles that trigger both detectors. Their assignment is to explain what’s happening—not a simple goal because each pair of photons is “entangled,” a quantum concept that means they are linked no matter how far they are separated. A change in one is instantly reflected in the other. Einstein dreamed up entanglement in 1935, explaining that it’s consistent with quantum laws but so absurd that it shows the theory’s defects. Amazingly, experiments proved that entanglement not only exists but has practical applications in computing, cryptography and even teleportation—of subatomic particles. Zeilinger uses simple diagrams and cheerful dialogues between Bob and Alice to make a difficult concept somewhat less difficult.

Not for the scientifically disinclined, but readers who pay close attention will grasp a strange but fascinating scientific principle.

LETTERS FROM AN ASTROPHYSICIST

A media-savvy scientist cleans out his desk.

Tyson (Astrophysics for People in a Hurry, 2017, etc.) receives a great deal of mail, and this slim volume collects his responses and other scraps of writing.

The prolific science commentator and bestselling author, an astrophysicist at the American Museum of Natural History, delivers few surprises and much admirable commentary. Readers may suspect that most of these letters date from the author’s earlier years when, a newly minted celebrity, he still thrilled that many of his audience were pouring out their hearts. Consequently, unlike more hardened colleagues, he sought to address their concerns. As years passed, suspecting that many had no interest in tapping his expertise or entering into an intelligent give and take, he undoubtedly made greater use of the waste basket. Tyson eschews pure fan letters, but many of these selections are full of compliments as a prelude to asking advice, pointing out mistakes, proclaiming opposing beliefs, or denouncing him. Readers will also encounter some earnest op-ed pieces and his eyewitness account of 9/11. “I consider myself emotionally strong,” he writes. “What I bore witness to, however, was especially upsetting, with indelible images of horror that will not soon leave my mind.” To crackpots, he gently repeats facts that almost everyone except crackpots accept. Those who have seen ghosts, dead relatives, and Bigfoot learn that eyewitness accounts are often unreliable. Tyson points out that extraordinary claims require extraordinary evidence, so confirmation that a light in the sky represents an alien spacecraft requires more than a photograph. Again and again he defends “science,” and his criteria—observation, repeatable experiments, honest discourse, peer review—are not controversial but will remain easy for zealots to dismiss. Among the instances of “hate mail” and “science deniers,” the author also discusses philosophy, parenting, and schooling.

THE JOHNSTOWN FLOOD

The Johnstown Flood was one of the greatest natural disasters of all time (actually manmade, since it was precipitated by a wealthy country club dam which had long been the source of justified misgivings). This then is a routine rundown of the catastrophe of May 31st, 1889, the biggest news story since Lincoln's murder in which thousands died. The most interesting incidental: a baby floated unharmed in its cradle for eighty miles.... Perhaps of local interest-but it lacks the Lord-ly touch.
