 In turn, Alejandro Cassini and Marcelo Levinas developed a fruitful collaboration studying different aspects of the history of physics at the beginning of twentieth century, particularly regarding Einstein’s works: Einstein’s reinterpretation of Michelson-Morley experiment (Cassini and Levinas 2005), his explanations of photoelectric effect (Cassini and Levinas 2008; Cassini, Levinas, and Pringe 2015) and of the Compton effect (Cassini, Levinas, and Pringe 2013), his reinterpretation of Fizeau experiment (Cassini and Levinas 2019), as well as the role played by the ether in the conceptual change to special relativity (Cassini and Levinas 2009). In the quantum context, Olival Freire Jr. (2015) published a book that traces the passionate foundational controversies that accompanied the ripening of quantum physics during the second half of the twentieth century.
