Happy Winter Solstice One and All!

Here’s an interesting solstice fact for you: the Earth is actually receiving more solar radiation at this time of year than at any other time. This is because the Earth does not orbit the sun in a circle, but in an ellipse. In the northern hemisphere winter the Earth is at its closest to the sun, a point called ‘perihelion’, but in summer it is at its furthest point, or ‘aphelion’.

The Guardian have published a little article on the timing of the winter solstice.

However, my favourite solstice image is on a different page. The same technique used in the photo on that page, from the same position, but on the summer solstice would probably not catch the sun at all, or perhaps just a glimpse of it in the top corners.

At this time of year the sun is always…

If someone had casually asked me to draw up a list of the people I was most likely to use as sources for my blogging over the coming week there would have been some predictable names. Nowhere in the top ten thousand names would the words ‘Nigella’ or ‘Lawson’ have appeared together. Regular blog readers will know how much I enjoy understanding the connection between phenomena such as the earth’s orbit around the sun and our daily lives. Christmas is such a time and, almost unbelievably, this is where we hand over to Nigella in her Christmas cookbook,

‘Biblical scholars generally tend to believe that Christ’s birth probably fell about six months after Passover, which would make it nearer September than December. However, the Roman Festival of Saturnalia – a time of merry-making, excess and misrule, precursor to the office party and much else besides – fell around the…
