New Theories / Re: Re: Critique of scientific method and will we ever find a theory of everything?

Could this be one of the rare mysteries where philosophy could provide the answer?

If we compare scientific theories to organisms, mutations can happen by several reasons, and what we call philosophy  are a source of them. But most of the mutations are failures. The role of natural selection is played by maths and experiments. Some mutations succeed and theories change.

I don't think of ancient philosophers considering life in stars or planets. Astronomy was a science of measuring time, through careful observation of the movement of celestial bodies. Other world was then closely related to after life.

When people tried to learn astronomy before Kepler in the school, at first it should be strange all that deferents, epicycles and equants to decribe the planets movements. But after become used to calculate, and see that it worked, it might become like a second nature.
Learning about Hermitian operators, state vectors or commutators may be something like that.

There is a nice video in youtube about this subject. It a lot more about light polarization, but at the end the demonstration is impressive.

See "Iron metallurgy in Africa" in wikipedia.

The cultural and technological shock felt by the Americans when the Europeans arrived in the 16th century  also (probably) happened for the Africans. But much earlier, when people knowing iron making technology started spreading across sub-Saharan Africa.

When the europeans arrived, the African kingdoms were stronger than their American equivalents, like Mexicans and Incas.

They were only fully conquered by XIX century European nations and their advanced weaponry.
