Half of March

We're half way through march, it snowed last week. Then it rained later in the day. I noticed there are still sodium street lamps where I live. Sodium is an alkali metal. If you pass a large current through Sodium, it turns into plasma. I think they picked that material because it appears the same colour as the sun. 

I remember reading a book called 'Dancing Wu Li Masters' by Gary Zukav, in the book it explains that sodium and hydrogen emit similar orange light when they turn into a plasma but the hydrogen plasma transmits more colours, over 100 of them and the sodium only transmits 2. They mix together to make an orange glow. The answer came from hydrogen not having any shells, the electron shells in atoms make it hard for electrons to move to different areas but hydrogen only has one electron so there are no shells inhibiting light transmission. 

It is nice to see the orange light of Sodium street lamps reflect off wet asphalt. It is like a little gold road.
