Renowned physicist Chen-Ning Yang has passed away at the age of 103, leaving behind a legacy that reshaped our understanding of fundamental forces in nature. His work on parity laws, which challenged the widely accepted notion of symmetry between left and right, earned him the Nobel Prize in Physics in 1957.
Yang's journey to this milestone began during his time at Princeton University's Institute for Advanced Study in the early 1950s, where he befriended Tsung-Dao Lee, another young Chinese émigré. Together, they revolutionized the field of physics by demonstrating that parity laws were not absolute and could be broken under certain conditions.
One of Yang's most significant contributions came from an idea conceived in 1953, which he developed with the help of Robert Mills. This theory, now known as Yang-Mills theories, successfully described the weak and strong nuclear forces, laying the foundation for modern particle physics. However, it was not without controversy; the acerbic theorist Wolfgang Pauli publicly questioned Yang's work, which nearly derailed his career.
Yang's insights were rooted in the success of quantum electrodynamics (QED), a theory that described the interaction between electrically charged particles and light. The key to QED was its "local gauge invariance," which ensured that its equations applied uniformly throughout space and time – a fundamental property known as "vector" or "gauge" invariance.
Yang's work on vector particles, which carry a sense of direction, challenged the conventional understanding of these entities. He proposed that massless vector particles could be responsible for certain forces, including the weak nuclear force. Although his initial ideas were met with skepticism, Yang persevered and eventually collaborated with Peter Higgs and others to develop a deeper understanding of the "mass mechanism" that confirmed the existence of massive vector particles – now known as W bosons.
Yang's contributions extended beyond particle physics; he also made significant contributions in statistical mechanics and condensed matter physics. In his later years, he played a crucial role in establishing large-scale research centers in China and received numerous awards for his work, including the US National Medal of Science.
Throughout his life, Yang remained devoted to his family and continued to push the boundaries of human knowledge until his passing at the age of 103. His legacy serves as a testament to the power of perseverance and innovation, inspiring future generations of scientists to tackle the most fundamental questions in physics.

103 is old for a genius like Chen-Ning Yang, but his impact on physics will live on forever 
I mean, who needs to be alive when you leave behind such revolutionary ideas? The Yang-Mills theories changed everything and even Pauli was impressed (eventually 
). It's crazy how he persevered despite skepticism and criticism – we could all learn from that! 
But seriously, the fact that his work on parity laws challenged conventional thinking is a huge deal. We're still exploring those ideas today 
. Rest in peace, Dr Yang 
at 103 tho! that's like, super old 
. i was reading about him in history class and his work on parity laws sounds so mind-blowing 
. but what i find really cool is that he didn't give up even when people doubted him 
like, wolfgang pauli was pretty harsh on him but yang just kept pushing forward. and now his legacy lives on and it's so inspiring 
just heard about Chen-Ning Yang's passing 
. But hey, it's all part of the journey, right?
.
.
just thinking about Chen-Ning Yang is mind blown... I mean, who else can say they won the Nobel Prize in Physics at 37?! 
And to think he had to deal with all that controversy from Wolfgang Pauli... talk about pressure! 
But what's amazing is how he persevered and ended up changing our understanding of fundamental forces in nature. The Yang-Mills theories are still a game-changer in particle physics today. 
I wish we knew more about his personal life, though... what was it like growing up as a Chinese émigré in the US? 
Did he have any other passions outside of physics? 
, it's crazy that he lived to be 103! The dude was like a superhero for science, saving our understanding of the universe from some pretty basic concepts 
. Anyway, we should all be thanking our lucky stars to have had this genius on our planet for so long 
. Anyway, it's crazy to think about how Yang-Mills theories are still influential today in particle physics. His legacy will definitely keep inspiring scientists for years to come 
.
just read about Chen-Ning Yang's passing and I gotta say it's kinda crazy that he lived for like 103 years and still had so much to give 
what I admire most about him though is how he never gave up even when people doubted him, like Wolfgang Pauli being all acerbic and crap 
but idk how much of his work is still relevant today... maybe someone can explain it to me in a way that makes sense 
103 years young and still slaying game! Chen-Ning Yang was a true legend in the physics world 
That Yang-Mills theory is still influencing modern physics today! 
. But we know how genius he was, right? The guy basically changed the game for particle physics! 
he was more than just a physicist, he was a pioneer who changed the game 
! He lived an amazing 103 years and left behind a legacy that changed our understanding of fundamental forces in nature 
. Yang-Mills theories are still helping us today, and his contributions to statistical mechanics and condensed matter physics are so inspiring 
. It's crazy that his work on parity laws and Yang-Mills theories revolutionized our understanding of fundamental forces in nature. And to think, he had to deal with all sorts of controversy along the way, including Pauli questioning his work - talk about perseverance!
