    Quantum mechanics didn’t supersede electromagnetism. Again, they’re different things. Electromagnetism is a fundamental interaction. Whereas quantum mechanics describes the mechanics of quantum particles. Whether those particles are affected by electromagnetic forces or not. It’s a description of how they behave at quantum scales.

    Coulomb’s law has nothing to do with quantum mechanics, it’s a description of how macroscopic charged particles interact. What the OP should have said to be correct is:

    Awesome to see the similarities between: Newton’s law of gravitation and Coulomb’s law

    I don’t know where he got quantum mechanics from.

    The relation between them is that they’re both forces that scale with the inverse square of the distance between the objects. Any force that scales with the inverse square of distance has pretty much the same general form.

    Another similarity is that both are incomplete, first approximations that describe their respective forces. The more complete versions are Maxwell’s laws for electromagnetism and General Relativity for gravity.








  • Some argue that transitioning to 100% renewable energy would be too slow to limit climate change, and that closing down nuclear power stations is a mistake.[122][123]

    “Nuclear power must be well regulated, not ditched”. The Economist. 6 March 2021. ISSN 0013-0613. Retrieved 31 January 2022. McDonnell, Tim (3 January 2022).

    In November 2014 the Intergovernmental Panel on Climate Change came out with their fifth report, saying that in the absence of any one technology (such as bioenergy, carbon dioxide capture and storage, nuclear, wind and solar), climate change mitigation costs can increase substantially depending on which technology is absent.
