physics & chemistry

The videos below explain current scientific theories regarding –
the emergence of matter and energy in the Universe as we know it:

I. The emergence of the Universe and initial stars

II. The emergence of heavy elements from dying stars

III. The emergence of solar systems and planets from heavy elements

IV. The only known planet where life emerged

For more detailed tutorials,
I highly recommend the Crash Course Series, specifically their:
“Big History” series for the emergence of the Universe through planetary formation
(just episodes #1-3)

and
“Chemistry” series for a comprehensive understanding of chemistry
