Thanks for posting the article Mike, it was insightful to read and understand the mindset of the 1920's.
Galaxies were called spiral nebula, light waves passing through the etheric etc.
Interesting how they measured the dimensions of stars even though in Betelgeuse case they were wrong as its now known to be much larger.
The transmutation of elements, the theory of fusing hydrogen to create helium and the by-product of energy that is released, forerunner of the hydrogen bomb.
What I liked was, it was easy to read and not mathematical gogglygoop.
Regards
Bill
