Two Japanese and a Japanese-born American have won the Nobel Prize in physics for discoveries in the world of subatomic physics, the Royal Swedish Academy of Sciences announced yesterday.
American Yoichiro Nambu, 87, of the University of Chicago, won half of the prize for the discovery of a mechanism called spontaneous broken symmetry in subatomic physics. Makoto Kobayashi and Toshihide Maskawa of Japan shared the other half of the prize for discovering the origin of the broken symmetry that predicts the existence of at least three families of quarks in nature.
“Spontaneous broken symmetry conceals nature’s order under an apparently jumbled surface,” the academy said in its citation. “Nambu’s theories permeate the standard model of elementary particle physics. The model unifies the smallest building blocks of all matter and three of nature’s four forces in one single theory.”
The Japanese-born Nambu moved to the US in 1952 and is a professor at the University of Chicago, where he has worked for 40 years. He became a US citizen in 1970.
“As early as 1960, Yoichiro Nambu formulated his mathematical description of spontaneous broken symmetry in elementary particle physics,” the citation said.
“Spontaneous broken symmetry conceals nature’s order under an apparently jumbled surface. It has proved to be extremely useful, and Nambu’s theories permeate the Standard Model of elementary particle physics,” it said.
Kobayashi and Maskawa “explained broken symmetry within the framework of the standard model but required that the model be extended to three families of quarks.”
Kobayashi, 64, works for the High Energy Accelerator Research Organization, or KEK, in Tsukuba, Japan. Maskawa, 68, is with the Yukawa Institute for Theoretical Physics at Kyoto University in Japan.
“The spontaneous broken symmetries that Nambu studied differ from the broken symmetries described by Makoto Kobayashi and Toshihide Maskawa,” the academy said. “These spontaneous occurrences seem to have existed in nature since the very beginning of the universe and came as a complete surprise when they first appeared in particle experiments in 1964.”
The academy added that it was only in recent years that scientists have been able to confirm the explanations that Kobayashi and Maskawa proffered in 1972.
“These predicted, hypothetical new quarks have recently appeared in physics experiments. As late as 2001, the two particle detectors BaBar at Stanford ... and Belle at Tsukuba, Japan, both detected broken symmetries independently of each other. The results were exactly as Kobayashi and Maskawa had predicted almost three decades earlier,” the citation said.
Maskawa yesterday paid tribute to Nambu.
“I am happy that Mr Nambu has won it. I thought there was a bigger chance this year,” Maskawa said, as quoted by Jiji Press.
Japanese Prime Minister Taro Aso was overjoyed when he learned about the Nobel prize during a high-level meeting on the global financial crisis, a minister said.
“When we heard the news, all of us clapped and the prime minister actually jumped for joy, saying, ‘That’s great news,’” Japanese Finance Minister Shoichi Nakagawa told reporters.
AIR SUPPORT: The Ministry of National Defense thanked the US for the delivery, adding that it was an indicator of the White House’s commitment to the Taiwan Relations Act Deputy Minister of National Defense Po Horng-huei (柏鴻輝) and Representative to the US Alexander Yui on Friday attended a delivery ceremony for the first of Taiwan’s long-awaited 66 F-16C/D Block 70 jets at a Lockheed Martin Corp factory in Greenville, South Carolina. “We are so proud to be the global home of the F-16 and to support Taiwan’s air defense capabilities,” US Representative William Timmons wrote on X, alongside a photograph of Taiwanese and US officials at the event. The F-16C/D Block 70 jets Taiwan ordered have the same capabilities as aircraft that had been upgraded to F-16Vs. The batch of Lockheed Martin
GRIDLOCK: The National Fire Agency’s Special Search and Rescue team is on standby to travel to the countries to help out with the rescue effort A powerful earthquake rocked Myanmar and neighboring Thailand yesterday, killing at least three people in Bangkok and burying dozens when a high-rise building under construction collapsed. Footage shared on social media from Myanmar’s second-largest city showed widespread destruction, raising fears that many were trapped under the rubble or killed. The magnitude 7.7 earthquake, with an epicenter near Mandalay in Myanmar, struck at midday and was followed by a strong magnitude 6.4 aftershock. The extent of death, injury and destruction — especially in Myanmar, which is embroiled in a civil war and where information is tightly controlled at the best of times —
China's military today said it began joint army, navy and rocket force exercises around Taiwan to "serve as a stern warning and powerful deterrent against Taiwanese independence," calling President William Lai (賴清德) a "parasite." The exercises come after Lai called Beijing a "foreign hostile force" last month. More than 10 Chinese military ships approached close to Taiwan's 24 nautical mile (44.4km) contiguous zone this morning and Taiwan sent its own warships to respond, two senior Taiwanese officials said. Taiwan has not yet detected any live fire by the Chinese military so far, one of the officials said. The drills took place after US Secretary
THUGGISH BEHAVIOR: Encouraging people to report independence supporters is another intimidation tactic that threatens cross-strait peace, the state department said China setting up an online system for reporting “Taiwanese independence” advocates is an “irresponsible and reprehensible” act, a US government spokesperson said on Friday. “China’s call for private individuals to report on alleged ‘persecution or suppression’ by supposed ‘Taiwan independence henchmen and accomplices’ is irresponsible and reprehensible,” an unnamed US Department of State spokesperson told the Central News Agency in an e-mail. The move is part of Beijing’s “intimidation campaign” against Taiwan and its supporters, and is “threatening free speech around the world, destabilizing the Indo-Pacific region, and deliberately eroding the cross-strait status quo,” the spokesperson said. The Chinese Communist Party’s “threats
