1. Jim Peebles is widely regarded as one of the world's leading theoretical cosmologists in the period since 1970, with major theoretical contributions to primordial nucleosynthesis, dark matter, the cosmic microwave background, and structure formation.
Jim Peebles was awarded half of the Nobel Prize in Physics in 2019 for his theoretical discoveries in physical cosmology.
Jim Peebles was born on April 25,1935, in St Vital in present-day Winnipeg, Manitoba, Canada, the son of Ada Marion, a homemaker, and Andrew Charles Jim Peebles, who worked for the Winnipeg Grain Exchange.
Jim Peebles completed his Bachelor of Science at the University of Manitoba.
Jim Peebles then went on to pursue graduate studies at Princeton University, where he received his Doctor of Philosophy degree in physics in 1962, completing a doctoral dissertation titled "Observational Tests and Theoretical Problems Relating to the Conjecture That the Strength of the Electromagnetic Interaction May Be Variable" under the supervision of Robert Dicke.
In 1964, there was very little interest in this field and it was considered a "dead end" but Jim Peebles remained committed to studying it.
Jim Peebles has made many important contributions to the Big Bang model.
Long before it was considered a serious, quantitative branch of physics, Jim Peebles was studying physical cosmology and has done much to establish its respectability.
Jim Peebles has a long record of innovating the basic ideas, which would be extensively studied later by other scientists.
Similarly, Jim Peebles contributed to establishing the dark matter problem in the early 1970s.
Jim Peebles was elected as a member of the American Academy of Arts and Sciences in 1977 and a member of the National Academy of Sciences in 1988.
