Science

Late last year, I published the first theoretical physics paper in which the main idea originated from artificial intelligence – from an AI. And my experience working with the most powerful AI models left me both impressed and wary. The most accurate analogy I can offer is that it’s like something familiar to anyone who has done research: a brilliant colleague who is also unreliable. This colleague can produce deep insights at surprising speed – and then, the next second, make an error that ranges from the trivial to the profound. That tension – capability versus reliability – has shaped how I now use these systems in mathematics and theoretical physics. It is also what will shape how they affect scientific research over the next few years.

On March 6, 1959, nine-year-old Candice "Candy" Rogers of Spokane, Washington, went out after school to sell campfire mints door-to-door. Sweet-natured with strawberry blonde curls and a button nose, she was small for her age. Her mother, Elaine, had one clear rule that Candy must be home before dark. But Candy never came home. Her disappearance triggered a 16-day manhunt involving thousands of people, the Marines and the US Air Force. In fact, three airmen lost their lives on the second day when their helicopter hit high tension cables and plummeted into the Spokane River.  After two weeks of searching for Candy, all detectives could find were her scattered mint boxes.

The Amazon reviews for David Deutsch’s The Beginning of Infinity don’t alert you to the fact that this is a book on theoretical physics. They sound more like a weepy divorcé’s YouTube comments below a Mark Knopfler guitar solo. “I didn’t so much read it,’ says one. “It read me.’ ‘I was honestly sad when it was over,’ writes another. “This book changed my way of seeing the world, politics, science and, most importantly, of seeing what I will understand as containing some truth.” When I talk to Deutsch – one of the most sensationally interesting theoretical physicists of our age – on Zoom, I see two beady eyes peering at me over some non-spectacular spectacles under a mess of thin white hair, borne by a thin white man in a thin white shirt.

What comes to mind when you think about the maximum amount of love a parent can have for their child?For me, I think of Dick Hoyt pushing his son Rick, who had cerebral palsy, in a wheelchair through the Ironman World Championship course. I think of the parents of Nick Vujicic, born without arms or legs, raising Nick with confidence, and cheering him on as he became an international motivational speaker. I think of the mother of a child with Down Syndrome, choosing each day to recognize the absolute gift of their child. I think of the parent at the dinner table comforting a child upset by a ‘C’ on their report card.Noor Siddiqui, founder of Orchid Biosciences, sees things differently.

The world received a jolt in 2018 – and it wasn’t from a Silicon Valley whiz or a lab at MIT. It came from Shenzhen, China, where a lanky, unassuming biochemist named He Jiankui did the unthinkable. Using the newly discovered CRISPR-Cas9 toolkit, and asking no one’s permission, He edited the genes of Lulu and Nana, twin baby girls, so that both were born immune to HIV. The scientific establishment gasped, jaws dropped and the moralists clutched their pearls. “Monstrous!” the bioethicists cried. “I was just horrified,” said Jennifer Doudna, who won the 2020 Nobel Prize in Chemistry for inventing the CRISPR gene-editing technique.

Scientists have released the largest map of the universe ever compiled. Millions of galaxies have been surveyed, stretching back 11 billion years, most of the age of the cosmos. According to many scientists, this data, combined with other observations, presages a major reassessment of what we know about the universe: possibly, for the first time, revealing a crack in Einstein’s theory of gravity. The Dark Energy Spectroscopic Instrument (DESI) is attached to a large telescope at the Kitt Peak National Observatory in Arizona. Each night it measures the positions of and distances to thousands of galaxies. Galaxies exist in groups and their motions are influenced by other, nearby galaxies.
