World clocks

World map clocks have always been popular ways of presenting the 24 hour clock and its basis in physical geography.

Here’s a picture of Tom Shannon’s Synchronous World Clock. (Thanks for the link, Tom.)

The map on the face is by Buckminster Fuller and Shoji Sadao. A limited edition of 20 was made in 1983.

If you’re looking for something a bit more basic, here’s Trintec’s World Clock:

You can find vintage versions of this Seiko compact world time clock for sale online. I think it was made in the 1970s or 1980s:

If you want a more abstract design, you might—if you’re very lucky—find a Willis World Clock from the 1930s:

Looking at all these world map clocks, I’m not sure whether the NorthPole-centered projections are more or less common than the SouthPole-centered ones. I suppose that one advantage of the SouthPole versions are that the clock’s motion can be clockwise, with the hands moving clockwise as the world rotates eastwards. With the NorthPole versions, the eastwards motion has to be reproduced with counter-clockwise motion.

News from the other hemisphere

There’s a well-known observation that 50% of the human population is less than average in terms of intelligence. Statisticians argue with the precise meaning of this statement, but, as someone else observes, “it just seems that way”!

This photograph, taken by Mark Serrels, Editorial Director at CNET News, is from a story that leaps happily onto the pile of evidence in support of the statement.

flat-earth-men

Serrels’ fascinating story, The Bizarre Tale of the Australia Flat Earth Convention that Fell Apart, is about the only two people who turned up to a flat-Earth convention in Australia. It starts off being funny, but soon becomes a sad tale of mental inadequacy and self-delusion.

In this photograph it’s difficult to see whether the convention audience (all two of them) are standing in front of a clock, or just a map that looks like a clock. The numbers around the edge are arranged counter-clockwise, and I can’t see whether it starts with a zero or ends with a 24. It looks like there’s some kind of wiggly pointer aiming to 13…

I think it would make a decent clock. And I don’t think it means that it should be taken literally as a representation of our world.

Projecting a spherical object onto a 2D surface has been a familiar challenge ever since the Greek and Arab astronomers developed the astrolabe, a 2D projection of a complex 3D system, well illustrated by this diagram from Wikipedia:

Astrolabe Stereographic projection on tympan

Clock makers have often used 2D projections of the Earth’s surface as the background for rotating dials, although some have introduced the added complexity of rotating globes, of both the moon and the Earth.

Elsewhere on this site there’s a brief investigation of the map projections that could be used to show most of the land masses on our Earth on a flat disk, suitable for use in a 24 hour clock:

I ought to remake this image, but for now this image from Wikimedia (by RokerHRO) will have to do:

Azimuthal Equidistant N90

It’s surprising that anyone could mistake this geometric construction for a life-like representation of our planet!

Svalbard 2018 range

Today’s the Winter Solstice in the UK, and the sun was visible for about 6 hours. Up in Svalbard, Latitude 78°13′N, longitude 15°38′E, though, the sun hasn’t risen for weeks, and won’t be seen again by anybody living there until February 15, 2018.

The Svalbard Company’s watches are inspired by the beautiful, extreme and challenging landscapes of Svalbard and are valued more for their elaborate artistry, aesthetic appeal and fashionable design than for simple timekeeping. The Svalbard company has released new models for 2018:
