In a new report now published in Nature Communications Physics, Pedro R. Dieguez and an international team of scientists in quantum technologies, functional quantum systems and quantum physics, developed a new framework of ...
Almost 400 years ago, in "The Assayer," Galileo wrote: "Philosophy is written in this grand book, the universe … [But the book] is written in the language of mathematics." He was much more than an astronomer, and this can ...
