1938 Majorana letter

The 1938 Majorana letter refers to a correspondence from physicist Ettore Majorana, who was known for his work on quantum mechanics. In this letter, he discussed complex ideas about the nature of particles and their interactions, particularly focusing on the concept of neutrinos—tiny, elusive particles that barely interact with matter. Majorana proposed a special type of neutrino, now called a "Majorana neutrino," which is its own antiparticle. This idea has significant implications in understanding the universe's fundamental particles and has influenced ongoing research in particle physics. The letter is valued for its insights into theoretical physics and Majorana’s innovative thinking.
