Murray Gell-Mann, the Nobel Prize-winning physicist who brought order to the universe by helping discover and classify subatomic particles, has died at the age of 89.
Gell-Mann died Friday at his home in Santa Fe, New Mexico. His death was confirmed by the Santa Fe Institute, where he held the title of distinguished fellow, and the California Institute of Technology, where he taught for decades. The cause was not disclosed.
Gell-Mann transformed physics by devising a method for sorting subatomic particles into simple groups of eight — based on electric charge, spin and other characteristics. He called his method the "eightfold way" after the Buddhist Eightfold Path to enlightenment.
Later Gell-Man developed the theory that identified "quarks," indivisible components of Earth's matter that make up protons, neutrons and other particles. Experiments confirmed the existence of quarks, and these objects now form the basis for our physical understanding of the universe, Caltech said in a statement.
"It would be hard to overestimate the degree to which Murray dominated theoretical particle physics during his heyday in the 1950s and 1960s. He contributed so many deep ideas that drove the field forward, many of which are just as relevant today," said John Preskill, the Richard P. Feynman Professor of Theoretical Physics at Caltech.
In 1969, Gell-Man was honored with the Nobel Prize in Physics "for his contributions and discoveries concerning the classification of elementary particles and their interactions."
Born and raised in New York City, Gell-Man received his bachelor's degree in physics from Yale University in 1948 and his Ph.D. from Massachusetts Institute of Technology in 1951.
In later years, Gell-Mann became interested in the issues of complexity at the heart of biology, ecology, sociology, and computer science. He co-founded the Santa Fe Institute to study complex systems and authored the 1994 book "The Quark and the Jaguar" to present his ideas to a general audience.
He is survived by his children Nicholas Gell-Mann and Elizabeth Gell-Mann; and stepson Nicholas Southwick Levis, according to the Caltech statement.
LAS VEGAS (AP) — A $12 billion passenger bullet train linking Las Vegas and the Los Angeles area was dubbed the first true high-speed rail line in the nation on Monday, with the private company building it predicting millions of ticket-buyers will be boarding trains by 2028.
“People have been dreaming of high-speed rail in America for decades,” said U.S. Transportation Secretary Pete Buttigieg before taking a stage with union representatives and company officials at the future site of a terminal to be built just south of the Las Vegas Strip. “It’s really happening this time."
Buttigieg cited Biden administration support for the project that he said will bring thousands of union jobs, boost local economies and cut traffic and air pollution.
Brightline West, whose sister company already operates a fast train between Miami and Orlando in Florida, aims to lay 218 miles (351 kilometers) of new track almost all in the median of Interstate 15 between Las Vegas and Rancho Cucamonga, California. It would link there with a commuter rail connection to downtown Los Angeles. A station also is planned in San Bernardino County’s Victorville area.
Company officials say the goal is to have trains exceeding speeds of 186 mph (300 kph) — comparable to Japan’s Shinkansen bullet trains — operating in time for the Summer Olympics in Los Angeles in 2028.
“I believe we’ll look back at today and say, ’This was the birth of an industry of high-speed rail,'” Brightline Holdings founder Wes Edens said Monday.
The company aims to link U.S. cities that are too near each other for air travel to make sense and too far for people to drive.
Las Vegas has no Amtrak service. The idea of a bullet train to Los Angeles dates back decades under various names including DesertXpress. Brightline West acquired the project in 2019, and company and public officials say it has all required right-of-way and environmental approvals, along with labor agreements.
Brightline received Biden administration backing including a $3 billion grant from federal infrastructure funds and recent approval to sell another $2.5 billion in tax-exempt bonds. The company won federal authorization in 2020 to sell $1 billion in similar bonds.
Brightline West says electric-powered trains will cut the four-hour trip across the Mojave Desert to a little more than two hours. It projects 11 million one-way passengers per year, with fares that Edens said will be comparable to airline ticket costs. The trains will offer rest rooms, Wi-Fi, food and beverage sales and the option to check luggage.
Officials hope the train line will relieve congestion on I-15, where drivers often sit in miles of crawling traffic while returning home to Southern California from a Las Vegas weekend. An average of more than 44,000 automobiles per day crossed the California-Nevada state line on I-15 in 2023, according to Las Vegas Convention and Visitors Authority data.
Florida-based Brightline Holdings' Miami-line debuted in 2018 and expanded service to Orlando International Airport last September with trains reaching speeds up to 125 mph (200 kph). It offers 16 round-trips per day with one-way tickets for the 235-mile (378-kilometer) distance costing about $80.
Other fast trains in the U.S. include Amtrak’s Acela, which can top 150 mph (241 kph) between Boston and Washington, D.C. But fast train connections for other U.S. cities have been floated, including Dallas to Houston; Atlanta to Charlotte, North Carolina; Chicago to St. Louis; and Seattle to Portland, Oregon. Most have faced delays.
In California, a proposed 500-mile (805-kilometer) rail line linking Los Angeles and San Francisco was approved by voters in 2008, but has been beset by rising costs and routing disputes. A 2022 business plan by the California High-Speed Rail Authority projected the cost had more than tripled to $105 billion.
