Currently Playing: Quantum wave equation before Schrödinger

Buy me a coffee and support the channel: https://ko-fi.com/jkzero Addendum to the theory of quantum mechanics proposed by Louis de Broglie in 1923. In this video I present the little known wave equation discovered by de Broglie to describe his matter waves before Schrödinger. Although incorrect, this corresponds to the early development of de Broglie's pilot-wave theory.
