Nobel Prize-winning physicist and astronomer Prof. Steven Weinberg passed away Friday at the age of 88, according to a statement from the University of Texas at Austin (UT Austin).
The cause of death has not yet been determined, though according to the Washington Post, he had been hospitalized for some time.
Born in 1933 in New York City to Jewish immigrants, Weinberg would go on to have a landmark career in academia. His most famous work was a paper he published in 1967 that discussed the interaction between electromagnetism and the weak nuclear force – two of the universe's four fundamental forces, which work as part of a unified electroweak force.
The equation-filled article discussed and theorized concepts and properties that had never been observed before, but which played key roles in the progression of the field. His predictions were supported in later years, including by the discovery of the Higgs boson particle in 2012 at CERN's Large Hadron Collider in Switzerland.
But Weinberg wasn't just known for his scientific fame and accomplishments. Rather, he was also a noted activist, working as a spokesman for science. He had spoken to Congress, lectured on the history and philosophy of science and made waves for taking a stand against concealed carry guns in UT classrooms.
But Weinberg was also an outspoken advocate of the State of Israel. This was especially noted in his 1997 essay, "Zionism and Its Adversaries."
He had also been an outspoken advocate against antisemitism, something he considered boycotting Israel to constitute.
"But given the history of the attacks on Israel and the oppressiveness and aggressiveness of other countries in the Middle East and elsewhere, boycotting Israel indicated a moral blindness for which it is hard to find any explanation other than antisemitism."
Weinberg is survived by his wife, UT Austin Law Prof. Louise Weinberg, and their daughter, Elizabeth.
