Anticlockwise

Up here in the northern hemisphere, the Sun passes from left to right through the sky (as indeed it should) each day. At night the Moon and stars do the same thing.

Therefore the shadow of the gnomon on a sundial progresses in a clockwise manner. As a result sundial dials were laid out with increasing numbers in a clockwise arrangement. 

This fact is what gives us clock faces that look like this.



So, in the antipodes, where the sun does things that are clearly wrong, and therefore sundials go backwards, do they make their clocks run anticlockwise?

Wicker dam

Well this is typical of Britain. We used to do things well. Sheffield steel was the envy of the world, people would queue round the block for the chance to buy a nice nylon shirt from Marks and Spencer or a brand new Vauxhall Velox. And now? Now we try to keep lake water in place with a pair of wicker fences.  It is this sort of woolly thinking that could lose us our Empire. You mark my words.

What's This?

What's this little thing then eh?   Well, let me tell you a story... We changed cars recently. The replacement car is awfully modern and features a USB port.   A USB port.. really? What is that for, do you charge your phone on it? No, in fact you connect your iPod* to it. However it will also accept a standard memory stick and play mp3 music files from folders directly. Now that is a cute trick, as I don't own an iPod*. However, I wouldn't want a conventional memory stick poking out of the car for all to see, so I set off in search of the smallest stick I can find. Here it is, a Busbi Mini 4GB stick. In the background are just some of the CDs and tapes I transferred to it. Even this version looks like it will hold about 40 albums, which is all we will need in the car. So, this leads me to a nostalgic moment. In order to convert the tapes to mp3, I had to record them on the PC, cut 25 minutes of audio into individual tracks and export as W...

Pompeii

No trip to the Bay of Naples is complete without a visit to Pompeii. This vast 270 acre site is almost too much to take in, particularly in the scant two hours we had with our coach guide. Here's a view of the Auditorium near the end of the visit. A chance to sit down and relax for a moment.  As always, click on the image for the full size version.   The plaster casts of the victims are a chilling and sombre sight in amongst all the ruins For a more relaxed and informative experience, I suggest Herculaneum, on the other side of Vesuvius. Unlike Pompeii, this was covered in volcanic ash and mud which created a anaerobic layer that led to the  preservation of wood and similar materials. Here is a panorama of the buried town that shows how far below the current ground level it is. Most of Herculaneum is under the more recent town. It was lost for centuries: Historians agreed the it and Pompeii were on the coast, but they were digging in t...
