New York: Nobel laureate and Americal theoretical physicist Steven Weinberg passed away on Friday.

He was 88.

He shared the Nobel prize for physics in 1979 with two others "for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles.”

Electromagnetism and weak interaction are two of the four fundamental interactions of the nature. The unified field theory developed by Weinberg and others “models them as two different aspects of the same force.” This is a very important component of the Standard Theory of the particle physics.

Steven Weinberg was born in New York City in 1933. He held the Josey Regental Chair in Science at the University of Texas in Austin.
