HOW THE HIPPIES SAVED PHYSICS

SCIENCE, COUNTERCULTURE, AND THE QUANTUM REVIVAL

An enthusiastic account of a coterie of physicists who, during the 1970s, embraced New Age fads and sometimes went on to make dramatic discoveries.

In his first book, Kaiser (Physics/MIT) paints a gloomy portrait of his field during that decade. The golden age of Einstein, Bohr, Heisenberg, Pauli et al was history. The Cold War and increased government support had vastly increased the number of physicists, including many who yearned to explore Einstein-style paradoxes and the nature of reality but were bored by classes which stressed mundane practical applications. In 1975, Berkeley graduate students took matters into their own hands, organizing an informal “Fundamental Fysiks Group.” They attracted like-minded hip doctorates, so discussions mixed quantum theory with the latest counterculture delights from LSD to Eastern mysticism to ESP. They received generous media attention, including a Time cover story and produced a flood of publications about the “new physics” including bestsellers such as Fritjof Capra’s The Tao of Physics. With financial support from unexpected sources such as the CIA (worried about possible Soviet PSI weapons) and various young millionaires including Werner Erhard, they explored complex, hitherto ignored areas such as Bell’s theorem and quantum entanglement while annoying the establishment by exploring their links to the paranormal. The end result was a transformation in cutting-edge physics and major discoveries in quantum information science, now a thriving industry. Readers will enjoy this entertaining chronicle of colorful young scientists whose sweeping curiosity turned up no hard evidence for psychic phenomena but led to new ways of looking into the equally bizarre quantum world.

A tiny book, not much bigger than a pamphlet, with huge potential impact.

NO ONE IS TOO SMALL TO MAKE A DIFFERENCE

A collection of articulate, forceful speeches made from September 2018 to September 2019 by the Swedish climate activist who was nominated for a Nobel Peace Prize.

Speaking in such venues as the European and British Parliaments, the French National Assembly, the Austrian World Summit, and the U.N. General Assembly, Thunberg has always been refreshingly—and necessarily—blunt in her demands for action from world leaders who refuse to address climate change. With clarity and unbridled passion, she presents her message that climate change is an emergency that must be addressed immediately, and she fills her speeches with punchy sound bites delivered in her characteristic pull-no-punches style: “I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act.” In speech after speech, to persuade her listeners, she cites uncomfortable, even alarming statistics about global temperature rise and carbon dioxide emissions. Although this inevitably makes the text rather repetitive, the repetition itself has an impact, driving home her point so that no one can fail to understand its importance. Thunberg varies her style for different audiences. Sometimes it is the rousing “our house is on fire” approach; other times she speaks more quietly about herself and her hopes and her dreams. When addressing the U.S. Congress, she knowingly calls to mind the words and deeds of Martin Luther King Jr. and John F. Kennedy. The last speech in the book ends on a note that is both challenging and upbeat: “We are the change and change is coming.” The edition published in Britain earlier this year contained 11 speeches; this updated edition has 16, all worth reading.

A tiny book, not much bigger than a pamphlet, with huge potential impact.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.

THE ORDER OF TIME

Undeterred by a subject difficult to pin down, Italian theoretical physicist Rovelli (Reality Is Not What It Seems: The Journey to Quantum Gravity, 2017, etc.) explains his thoughts on time.

Other scientists have written primers on the concept of time for a general audience, but Rovelli, who also wrote the bestseller Seven Brief Lessons on Physics, adds his personal musings, which are astute and rewarding but do not make for an easy read. “We conventionally think of time,” he writes, “as something simple and fundamental that flows uniformly, independently from everything else, uniformly from the past to the future, measured by clocks and watches. In the course of time, the events of the universe succeed each other in an orderly way: pasts, presents, futures. The past is fixed, the future open….And yet all of this has turned out to be false.” Rovelli returns again and again to the ideas of three legendary men. Aristotle wrote that things change continually. What we call “time” is the measurement of that change. If nothing changed, time would not exist. Newton disagreed. While admitting the existence of a time that measures events, he insisted that there is an absolute “true time” that passes relentlessly. If the universe froze, time would roll on. To laymen, this may seem like common sense, but most philosophers are not convinced. Einstein asserted that both are right. Aristotle correctly explained that time flows in relation to something else. Educated laymen know that clocks register different times when they move or experience gravity. Newton’s absolute exists, but as a special case in Einstein’s curved space-time. According to Rovelli, our notion of time dissolves as our knowledge grows; complex features swell and then retreat and perhaps vanish entirely. Furthermore, equations describing many fundamental physical phenomena don’t require time.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.
