This weekend, the entire physics community is mourning!
One of the greatest physicists in the world and master of particle physics-Steven Weinberg (Steven Weinberg) passed away at the age of 88.
He established a unified theory of weak interaction and electromagnetic interaction and became one of the founders of the Standard Model of Particle Physics. He won the Nobel Prize in Physics in 1979.
In addition to his identity as a physicist, he is also a science ambassador and is passionate about science communication.
His “Gravity and Cosmology”, “The First Three Minutes”, and “The Dream of Ultimate Theory” have had a profound impact on scientists in various fields and science enthusiasts around the world. Hawking was also inspired by him to write ” A Brief History of Time .”
In November last year, at the Tencent WE Conference, he also sent a message to young Chinese scientists:
You have your mission, which is to explain these huge and mysterious figures related to different phenomena in nature.
This spring, he is still teaching and educating people and spreading scientific knowledge on campus.
University of Texas at Austin School school long Jay Hartzell said:
The death of Steven Weinberg is a loss to the University of Texas and society. Professor Weinberg has uncovered the mystery of the universe for millions of people, enriching the concept of human nature and our relationship with the world.
He changed the world.
In addition, it also caused a lot of scholars to deeply cherish him.
This is a special scholar who was inspired by Weinberg’s books when he was a child, followed all the way, and is now a university professor.
The life of Stephen Weinberg
In May 1933, Weinberger was born into a Jewish family in New York, USA.
Encouraged by his father in his early years, he developed a keen interest in theoretical physics at the age of fifteen or sixteen. Followed by Cornell opened a four-year college career University of Seoul.
Later, Weinberg studied at the Copenhagen Institute of Theoretical Physics and Princeton University for postgraduate studies, and received a doctorate from Princeton University.
After that, he went to Columbia University and Lawrence Radiation Laboratory to complete postdoctoral work.
Since 1960, he began a teaching career, successively serving as professors at UC Berkeley, MIT, and Harvard.
It was the year when MIT was teaching, Weinberg proposed a unified electromagnetic interaction and weak interaction model, now called the electroweak theory, and published it in Physical Review Letters. The paper is only three pages.
To this day, this article is still one of the most cited research papers in history, with 17,915 citations.
After 1967, the standard model of elementary particle theory gradually developed with the efforts of many people.
In 1979, six years after the discovery of the neutral current (that is, the discovery of the Z boson ), Weinberg, Glashaw, and Salam independently proposed the electroweak theory based on the spontaneous symmetry breaking mechanism and obtained the Nobel Physics Academic awards.
In 1982, he came to the University of Texas at Austin and taught physics and astronomy for decades.
Because of his outstanding achievements, he has won many important awards, including the Dannie Heineman Prize in Mathematical Physics in 1977, the National Medal of Science in 1991, and the Special Breakthrough Prize in Fundamental Physics last year.
Four suggestions for graduates
In 2003, he published Four golden lessons on Nature, giving some advice to college graduates who are about to enter a research career. They are still useful today.
It can be briefly summarized as four:
1、No one knows everything, and you don’t have to.
No one knows everything, and you don’t need to.
2、Go for the messes – that’s where the action is.
March into chaos, because there is so much to do
3、Forgive yourself for wasting time .
Forgive yourself for wasting time.
4、Learn something about the history of science,or at a minimum the history of your own branch of science.
Learn something about the history of science, at least in your field of research.
Finally, he ends with a public speech:
When I was a graduate student in the 1950s, I envied the achievements of our predecessors in the field of quantum electrodynamics, and our generation of theoretical physicists established the Standard Model to further advance the achievements of our predecessors.
The Standard Model explains all other forces that exist in nature and other particles we have discovered. Only gravity does not give an explanation. Our (theoretical physicists) work has not yet been completed. The Standard Model that we are proud of is not the final answer.
Now, he has passed the baton into the hands of the young man.
