Weather West with Daniel Swain PhD

If you want a really good, science based source of information on climate and weather in the Western US, this is the best YouTube based site I've found. https://www.youtube.com/watch?v=KJrPxdzBNKY&list=TLPQMDQwMzIwMjZYu5HwAjf0iQ&index=5&pp=iAQBsAgC

"The answer" to life, the universe & everything... (No, it's not 42, but it is a dimensionless real number): α (alpha), equal to the strength of the electromagnetic interaction between elementary charged particles:

α = ⁠e²4πε₀ħc ⁠≅ 1/137

where 
e is the elementary charge (~1.602×10⁻¹⁹ C);
h is the Planck constant (~6.626×10⁻³⁴ J⋅Hz⁻¹);
ℏ is the reduced Planck constant, ⁠(h/2π⁠ (~1.055×10⁻³⁴ J⋅s);
c is the speed of light in a vacuum(~300Km⋅s⁻¹);
ε₀ is the electrical permittivity of space (~8.854×10⁻¹² F⋅m⁻¹);
μ₀ is the magnetic permeability of space (~1.2567×10⁻⁶ N⋅A⁻²).
As far as anyone knows, having no reason to suspect otherwise, this is and always has been and always will be true everywhere in the universe, but no one really knows why, if there is a why, this number has the value it does.
