Abrahamic religion Updated 2025-07-16
It is just mind blowing that Christians, Muslims and Jews can have so many conflicts considering that their religions are basically the same. Uncanny valley comes to mind. See also remarks at: cirosantilli.com/china-dictatorship/zhong-gong
The transfiguration of Jesus is a notable example where Jesus/the Church tries to divert older religions into him. And then Muhammad does the same during isra and Mi'raj, and meets up with Jesus, John the Baptist and Abraham. The Kaaba was also clearly an earlier place of worship of local religions before Muhammad. But of course, Abraham was one of the builders of the Kaaba, so all good.

Polarization of light Updated 2025-07-16
This section discusses the pre-photon understanding of the polarization of light. For the photon one see: photon polarization.
People were a bit confused when experiments started to show that light might be polarized. How could a wave that propages through a 3D homgenous material like luminiferous aether have polarization?? Light would presumably be understood to be analogous to a sound wave in 3D medium, which cannot have polarization. This was before Maxwell's equations, in the early 19th century, so there was no way to know.
