About This Course
Science! But not mathematical…
About cause and effect, evolution and origin, how and why…
Not merely descriptions of ‘what’s out there’
One thing I have learned in a long life: that all our science, measured
against reality, is primitive and childlike – and yet it is the most
precious thing we have.
A. Einstein
Astronomy is Physics
…and Physics Explains Everything!
…within certain limits, that is!
Pure Physics can’t explain our deepest emotions, or our aesthetic responses to a beautiful sunset or glorious music*.
(*but see Musicophilia, by Oliver Sacks,or This is Your Brain on Music, by Daniel
Levitin)
The Beauty of Roses
Galileo Galilei
La mathematica e l'alfabeto nel quale Dio ha scritto l'universo.
(Mathematics is the alphabet with which God has written the universe.)
Einstein’s “Field Equations”
As you can see by following the link, much of astrophysics is intimidatingly mathematical!
