I forgot to put the clocks back last night. No real problem, it just meant I got an extra hour in bed. What does sadden me is that it’s 5.15pm and its already dark. Sometimes in the winter months it feels like you never see the sun. It hides behind the clouds, keeping its light lost in their faces.

As the year turns in the northern hemisphere the sun sinks further south, rising in an arc that tops at an angle, so consequently there is less daylight. In the southern hemisphere the earth is tipped towards the sun bringing more light to that part of the world.

Celestial mechanics is interesting. The fact that the earth is tipped on its axis is the cause. If the earth was upright all parts would have exactly 12 hours of daylight and night, there would be no seasons. But the angle of the earth would wobble more without the moon. It helps stabilise its orbit around the sun. Look things up, find things out, you might be surprised!
