Bethe–Salpeter Equation
The Bethe–Salpeter equation (BSE, named after Hans Bethe and Edwin Salpeter) is an integral equation, the solution of which describes the structure of a relativistic two-body (particles) bound state in a covariant formalism quantum field theory (QFT). The equation was first published in 1950 at the end of a paper by Yoichiro Nambu, but without derivation. Due to its common application in several branches of theoretical physics, the Bethe–Salpeter equation appears in many forms. One form often used in high energy physics is : \Gamma(P,p) =\int\!\frac \; K(P,p,k)\, S(k-\tfrac) \,\Gamma(P,k)\, S(k+\tfrac) where \Gamma is the Bethe–Salpeter amplitude (BSA), K the Green's function representing the interaction and S the dressed propagators of the two constituent particles. In quantum theory, bound states are composite physical systems with lifetime significantly longer than the time scale of the interaction breaking their structure (otherwise the physical systems under consi ...

Salpeter Initial Mass Function
In astronomy, the initial mass function (IMF) is an empirical function that describes the initial distribution of masses for a population of stars during star formation. IMF not only describes the formation and evolution of individual stars, it also serves as an important link that describes the formation and evolution of galaxies. The IMF is often given as a probability density function (PDF) that describes the probability for a star to have a certain mass during its formation. It differs from the ''present-day mass function'' (PDMF), which describes the current distribution of masses of stars, such as red giants, white dwarfs, neutron stars, and black holes, after some time of evolution away from the main sequence stars and after a certain amount of mass loss. Since there are not enough young clusters of stars available for the calculation of IMF, PDMF is used instead and the results are extrapolated back to IMF. IMF and PDMF can be linked through the "stellar creation function ...

Edwin Ernest Salpeter
Edwin Ernest Salpeter (3 December 1924 – 26 November 2008,) was an Austrian–Australian–American astrophysicist. Life Born in Vienna to a Jewish family, Salpeter emigrated from Austria to Australia while in his teens to escape the Nazis. He attended Sydney Boys High School (1939–40) and Sydney University, where he obtained his bachelor's degree in 1944 and his master's degree in 1945. In the same year he was awarded an overseas scholarship and attended the University of Birmingham, England, where he earned his doctorate in 1948 under the supervision of Sir Rudolf Peierls. He spent the remainder of his career at Cornell University, where he was the James Gilbert White Distinguished Professor of the Physical Sciences. Salpeter died of leukemia at his home in Ithaca, New York on 26 November 2008. Scientific contributions In 1951 Salpeter suggested that stars could burn helium-4 into carbon-12 with the Triple-alpha process not directly, but through an intermediate metastab ...

Greta Salpeter
Greta Morgan Salpeter (born February 12, 1988) is an American singer-songwriter and musician based in Los Angeles, California. Her career began in 2005 as singer/pianist of the Chicago-based band the Hush Sound. She later formed the band Gold Motel, whose debut album was released on June 1, 2010. Since 2014, she performs under the name Springtime Carnivore and has released two albums. Music career Morgan began learning piano at a young age, studying classical music. She first met Bob Morris, guitarist/vocalist in 2001. The two started playing together and created the Hush Sound, later recruiting Chris Faller on bass and Darren Wilson on drums. She was 16 when she began touring with the Hush Sound. In 2009, Morgan began recording material with the band Gold Motel. Together with La Sera's Katy Goodman, Morgan formed the duo Books of Love; they released the song "Space Time" in 2013. In 2012, Morgan began working on a solo project called Springtime Carnivore and recorded a six ...

Lonah Chemtai Salpeter
Lonah Korlima Chemtai Salpeter (, , born 12 December 1988) is an Israeli Olympic runner. Born in Kenya, she represents Israel internationally. She won the bronze medal in the marathon at the 2022 World Athletics Championships. At the European Athletics Championships in the 10,000 metres, Salpeter won the gold medal in 2018, and earned a bronze medal in 2022. She won the 2020 Tokyo Marathon, won the silver medal at the 2022 New York City Marathon, and finished third at the 2023 Boston Marathon. Her personal best time for the marathon is 2:17:45, which Salpeter ran in 2020 and which made her the sixth-fastest female marathon runner in history (currently, she is the 11th), the second-fastest European of all time, and set a new Israeli national record. Salpeter represented Israel at the 2016 Rio Olympics and the 2020 Tokyo Olympics. As of November 2022, she held six Israeli national records, over distances ranging from 3000 metres to the marathon. Salpeter represented Israel at ...

Miriam Salpeter
Miriam (Mika) Salpeter (née Mark; April 8, 1929 – October 24, 2000) was an American academic. As professor of neurobiology at Cornell University, she developed quantitative electron microscopic autoradiography as a means to investigate the neuromuscular junction. The Society for Neuroscience created the Mika Salpeter Lifetime Achievement Award in her honour. Early life and education Salpeter was born in Riga. Her father was a Yiddish scholar and Salpeter was fluent in Yiddish. During the rise of Nazi Germany Salpeter emigrated from Latvia to Canada, before moving to the United States in 1945. Salpeter attended high school in New York City. She was an undergraduate student at Hunter College, where she was a member of Phi Beta Kappa and graduated ''summa cum laude''. Salpeter moved to Cornell University for her doctoral studies, where she earned a PhD under the supervision of Howard Liddell. She spent a year at the Australian National University before returning to Cornell Un ...
