Talk:Theory of relativity (view source)
Revision as of 07:34, October 16, 2009
, 07:34, October 16, 2009→Quantum Field Theory/Changes to the Intro: Magnetism is understood as a relativistic effect
:::::Sorry to butt in, but I'm wondering how relativity is at all linked to modern electronics. From my (admittedly limited) knowledge, quantum mechanics fundamentally underpins modern electronics (CPU design has to account for quantum tunneling, etc.), but the precepts of relativity are totally irrelevant at the microscopic scale.

:::::: No, relativity is not irrelevant. Magnetism is understood as a relativistic effect. The theories that make Maxwell, Dirac, and Feynman famous are all relativistic. [[User:RSchlafly|RSchlafly]] 03:34, 16 October 2009 (EDT)
