## visible light – Why is the sky not purple?

The Question : 69 people think this question is useful I realise the question of why this sky is blue is considered reasonably often here, one way or another. You can take that knowledge as given. What I’m wondering is, given that the spectrum of Rayleigh scattering goes like $\omega^4$, why is the sky not

## newtonian mechanics – Why does the atmosphere rotate along with the earth?

The Question : 93 people think this question is useful I was reading somewhere about a really cheap way of travelling: using balloons to get ourselves away from the surface of the earth. The idea held that because the earth rotates, we should be able to land in a different place after some time. As

## thermodynamics – Explain it to me like I’m a physics grad: Greenhouse Effect

The Question : 101 people think this question is useful What is the mechanism by which increasing $\rm CO_2$ (or other greenhouse gases) ends up increasing the temperature at (near) the surface of the Earth? Mostly what I’m looking for is a big-picture explanation of how increasing $\rm CO_2$ affects the Earth’s energy transfer balance

## atmospheric science – Is the butterfly effect real?

The Question : 129 people think this question is useful Is the butterfly effect real? It is a well-known statement that a butterfly, by flapping her wings in a slightly different way, can cause a hurricane somewhere else in the world that wouldn’t occur if the butterfly had moved her wings in a slightly different
