Chen-Ning Yang, the trailblazing Chinese American physicist who passed away at the remarkable age of 103, left behind an indelible mark on the world of physics. His groundbreaking work revolutionized our understanding of fundamental forces and laid the foundation for today's successful theories.
In 1956, Yang and his colleague Tsung-Dao Lee shook the scientific community by challenging the widely accepted "parity laws," which posited that the forces acting on subatomic particles are symmetric between left and right. Their discovery overthrew this concept of "mirror symmetry" and earned them the Nobel Prize in Physics.
However, it was Yang's earlier work on gauge theory that proved to be a game-changer. In 1953, he attempted to build a theory describing the nuclear force between protons and neutrons using similar ideas that had been successful for quantum electrodynamics (QED). This bold endeavor led to the development of what is now known as Yang-Mills theories – the foundation upon which our understanding of the strong and weak nuclear forces is built today.
Yang's innovative work in this area was not without its challenges. A meeting with renowned physicist Wolfgang Pauli, who was notorious for his acerbic comments, left a lasting impression on Yang. During the seminar, Pauli posed a seemingly simple question – "What is the mass of these vector particles?" – only to find that Yang and his colleague Robert Mills had not yet come up with a definitive answer.
Despite this setback, Yang persevered, and his work ultimately led to the discovery of massive, charged particles known as W bosons, which are responsible for some radioactive decays. The strong nuclear force is also described by Yang-Mills theory – quantum chromodynamics (QCD) – where the "charge" is known as "colour," carried by quarks.
Yang's legacy extends beyond his work on fundamental forces. He made significant contributions in statistical mechanics and condensed matter physics, and played a crucial role in establishing large-scale research centers in China. His numerous awards include the US National Medal of Science (1986) and the Albert Einstein medal in 1995.
Born in Hefei, China, Yang's journey to becoming one of the most renowned physicists of his time was marked by both triumph and tragedy. After completing his PhD at the University of Chicago, he won a scholarship to pursue further studies in the US. He went on to become an Albert Einstein professor of physics at Stony Brook University, where he remained until his retirement in 1999.
Yang's remarkable life came full circle when he renounced his US citizenship in 2015, returning to China, where he continued to contribute to scientific research and institutions that bear his name.

I'm so sad to hear about Chen-Ning Yang's passing at such an incredible age. He truly left a lasting impact on the physics community 
. It's mind-blowing to think about how his work on gauge theory paved the way for our understanding of the strong and weak nuclear forces 
. I can only imagine the struggles he faced, especially during that meeting with Wolfgang Pauli 
. But what's most inspiring is how he persevered and went on to make groundbreaking contributions in other areas like statistical mechanics 
. His legacy extends far beyond his work, as a true pioneer who helped shape the next generation of scientists 
.
He was truly a pioneer in the field of physics, leaving behind an indelible mark on our understanding of fundamental forces 
. His work on gauge theory and Yang-Mills theories was instrumental in shaping the strong and weak nuclear forces we know today 
️.
. Yet, his groundbreaking research ultimately led to the discovery of W bosons and paved the way for quantum chromodynamics (QCD) 
.
. His legacy is truly a testament to his dedication and passion for science 
.
. But his work will continue to inspire future generations of scientists and researchers 
.
. I mean, the guy was still contributing to physics at 103 years old! What an inspiration for all of us to keep pushing boundaries and exploring new ideas 
. I'm definitely going to look into more of his work now...
103 & still changing the game! Chen-Ning Yang's legacy will keep on inspiring future geniuses 
But seriously, his work on gauge theory and Yang-Mills theories is still fundamental to our understanding of the strong and weak nuclear forces today. It's mind-blowing stuff! 
Is it a clever move to get back into China, or is he just trying to escape the fame and fortune that comes with being a genius physicist? 
Or maybe he just didn't want the attention until he was good and ready... hmm, too many questions! 
.
. i mean, what if yang's work wasn't just about physics but also about somethin' bigger? idk, but it's definitely make me wonder 
! I mean, who else can say they changed the way we think about fundamental forces? He's got to be one of the most influential scientists of all time 
. His work on gauge theory and Yang-Mills theories is still a game-changer today 
.
. I bet that was like getting roasted by your boss, but he just kept pushing forward 
. And can you believe he renounced his US citizenship in 2015 and returned to China? Talk about going full circle 
.
. He's definitely an inspiration for anyone who loves science or just wants to make a difference 
Yang was so cool! He basically created the foundation for our understanding of how particles interact with each other in physics. I mean, to challenge something as widely accepted as parity laws was huge, and his work on gauge theory led to some massive breakthroughs. It's crazy that he had a meeting with Wolfgang Pauli and still managed to make it big! 
Yang's legacy is so inspiring, especially considering he did all this at an old age. And what's up with him renouncing US citizenship in 2015? 
, and its kinda cool that he even got to see the W bosons being discovered after decades of work 
. His work on gauge theory and Yang-Mills theories is still mind-blowing to me, it's crazy how much of a game-changer it was for our understanding of the strong and weak nuclear forces. And can you believe he had a meeting with Wolfgang Pauli that left him shaken? 
I remember reading about that in school too... it's wild to think about how Yang persevered despite those setbacks.
. Chen-Ning Yang's story is an inspiration, but it also makes me think about how much pressure and stress our kids are under to succeed from such a young age 
.
he was literally a game-changer in physics dude. like, can you believe how old he got? 103 is insane! 
, you know how they have those cool experiments with the Upside Down portal? reminds me of Chen-Ning Yang's work on gauge theory and the strong nuclear force 
. It's wild to think about how his discoveries laid the foundation for our understanding of fundamental forces in physics 
It just goes to show that sometimes, pioneers have to blaze their own trails and break new ground.
