Have you got the globes? No, I always walk this way!

Sorry, I couldn’t help myself. When I started penning the title to this column, I began with "Have you got the globes?" and then the British comedy duo Morecambe and Wise popped into my mind, and I could imagine Ernie Wise asking this question and I could hear Eric Morecambe respond "No, I always walk this way!" (The old jokes are the best ones :-)
But that's not what I wanted to talk to you about…
Yesterday evening I was chatting with my wife (Gina the Gorgeous) about a friend of ours who recently adopted a young kid from China. I'm not sure how it came about, but I suggested that it might be a good idea for them to have a World Globe to they could talk about where we are and where China is and suchlike.
So I went for a rummage in my study, and emerged triumphant with just such a globe, which had been basking in the back of the closet. I was going to give the globe to Gina to give to our friend, but then I started looking at it in more detail, and I got sucked in…
You tend to forget just how much more information there seems to be when you are looking at globe as opposed to a flat map / projection. You get a much better impression as to how all of the countries relate to each other spatially. To be perfectly honest, I was amazed by how many things I found I didn’t know. I spent half my time saying "So that's where that is!" and the other half saying "What the heck is that?"
When coupled with my trusty iPad, the result is almost a case of information overload. Have you heard of San Marino, for example? Also known as the Most Serene Republic of San Marino, this is an "Enclaved Microstate" surrounded by Italy.
Only 24 square miles in size, and with a population of around 30,000, it turns out that San Marino is the oldest surviving sovereign state and constitutional republic in the world. It started as a monastic community founded on 3 September 301, and the constitution of San Marino, which was enacted in 1600, is the world's oldest constitution still in effect.
Or what about Indonesia? I'm ashamed to say that if you had asked me yesterday morning, I would have known hardly anything about this country. If pushed, I would have taken a stab and said it was somewhere in the Asia-Pacific region, but I couldn’t have told you if it was part of a continent or an island.
In fact, it turns out that Indonesia is an archipelago comprising approximately 17,508 islands! If you are American, think how hard it is remembering the names of the 50 states. In my case, being English, I just tried to jot down the names of all the English counties, and I came out painfully short. So can you imagine being the citizen of a country formed from 17,500+ islands? How would you like to be a geography teacher in an Indonesian school? With over 238 million people, Indonesia is the world's fourth most populous country, which makes it all the more embarrassing that I know so little about it!
And speaking of continents, what exactly is a continent and how many are there? (I've mentioned this before, but it's a question that's well worth pondering.) The conventional definition of a continent is that it is a large, continuous, discrete mass of land, ideally separated by expanses of water. The only small problem with this definition – a teeny tiny fly in the soup, as it were – is that many of the seven most commonly recognized continents identified by convention (Asia, Africa, North America, South America, Antarctica, Europe, and Australia) are not in fact discrete landmasses separated by water.
Actually, depending on your point of view, there are either seven, six, six, five, or four continents. Yes, I know I said six twice. This is because one flavor of six continents has North America and South America as separate continents, while Eurasia (Europe and Asia) is considered to be a single continent. An alternative point of view has America as a single continent that encompasses both North and South America, while Europe and Asia are considered to be two distinct entities.
The seven-continent model is usually taught in China, India, and most English-speaking Countries, while the six-continent (combined-America) model is taught in Latin America and some parts of Europe.
By some strange quirk of fate, this leads us back to the Olympics (see my recent blog The 2012 Olympics opening ceremony … WOW!) Have you ever wondered why the Olympic logo features five rings?

Well, the Olympics uses a six-continent model as a starting point, but it then excludes Antarctica on the basis that it makes sense (in the context of athletic competition) to include only the inhabited continents – hence the five-continent model.
But that's not what I wanted to talk to you about…
Back to my globe, which I am NOT giving to our friend's kid! It's mine, all mine, I tell you! (We can buy them one for Christmas.) We've all seen images of different continents and super-continents from hundreds of millions of years ago. Names like Yigarn, Vaalbara, Ur, Rodinia, Gondwana, and Pangaea spring to mind (Click Here to see an amazing animation showing the continents drifting around the globe).
Well, it just struck me that I would love to have a collection of world globes reflecting the state of play at different times, like 550 million years ago, 250 million years ago, and 65 million years ago. The last one is, of course, particularly "close to home" temporally speaking. How many times have you heard that a giant meteorite struck the earth 65 million years ago wiping out the dinosaurs? How many times have you heard that it formed a crater 180 kilometers (110 miles) in diameter, and that it landed off the coast of the Yucatán Peninsula in Mexico?
OK … now here's the big question, where exactly was the Yucatán Peninsula 65 million years ago in relation to everything else? I believe that part of North America was connected to Scotland at that time, so I'm guessing that North America was separated from South America.
I could look this up on the Internet, but I'm gasping for another cup of coffee, so this will have to wait until later. In the meantime, do you know of anyone who sells World Globes showing the continents 550, 250, and 65 million years ago? If so, please let me know, because based on how much additional information I'm gleaning from my present-day World Globe, I really would like to see the ancient continents presented in this way.

It sounds like you want a spherical display. Such could allow animations presenting historical (or geological) information. With (color) electronic ink such a display would not need to be powered when not changing. Of course, such a display would be extremely expensive (not just from the display area but I suspect significant R&D would be needed to develop a curved display and other desirable features). (Using a wireless data connection and perhaps induced current for power might allow one to avoid plugs.)
It looks like your globe is recent enough to include Macedonia but not so recent as to include South Sudan. Perhaps a new globe would be a better gift, though political maps change all too rapidly.

I REALLY like that idea of creating a globe using electronic paper ... hmmmmm

Unfortunately, the cost per unit--especially at low volume since even the manufacturing probably would have high NRE--of an electronic paper version would be extremely high. Support for color and fast refresh is also still somewhat new (so expensive). (And a high price would constrain sales volume, with the obvious effect on the price required to break even.)
I would guess that an active display would be more affordable, perhaps using something like Texas Instruments' DLP technology. (I am guessing that the micromirrors could be programmed to project onto a moderately diffusive curved surface. For lower volumes maximizing the use of commodity hardware--even at significant cost in software development--would seem to be important.)
Electronic paper would be so much nicer (visually and in terms of power consumption) than a projection-based globe, but I suspect the NRE would be far too great. (I doubt any makers of electronic paper would produce such a globe for the purpose of marketing.)
Perhaps I am excessively pessimistic--I admit I know almost nothing about the constraints of electronic paper--, but such a globe does not seem economically practical in the near future.

On the perhaps slightly positive side, there is a Science on a Sphere system at McWane Science Center in Birmingham, Alabama (http://www.mcwane.org/ ). This might be sufficiently close to you that you could go and see what future generations might have in a smaller and less expensive form.
Also, my pessimistic view need not correspond to reality.

If thats what happens when you look at a globe, what happens when you open Google Earth? And then start zooming in and out? And going for a stroll in the neighbourhood with streetview? You could be days in front of the computer screen. To me, the most amazing feature of Google earth is the fact that all that information is free, gratis, and for naught. (And the fact that like in Disney movies, the sun is always shining in Google earth).

I agree -- I love Google Earth -- when my wife and I are watching a travel program on TV (like "House Hunters International" on the Home and Garden Channel, for example), I almost invariable bring up Google Earth on my iPad to get a better "feel" for the place...
But I have to tell you that I am amazed just how "different" it feels to have an old fashioned physical globe in front of you -- I'm seriously thinking of getting a much larger (36" diameter) one -- if I can find one that's affordable...

Thinking of the possibilities, a globe with built-in electronic animation that would show human migration, and present human population densities.
Perhaps, it could spare so much life loss, in those places that have such hostile conditions.

I am really REALLY enthused by this idea. There are so many things you could do with this -- starting with showing the continents as them moved over time -- then as you say human migrations -- and evolving political / country boundaries...

The globe has come off the shelf for the Olympics at my place, with the kids looking up countries during the opening ceremony and when a competitor's nation takes their fancy. A good way to learn.
Of course, memorising all of the states is easy if you live in Australia. ;-)

I think the true scale and proportion (i.e. lack of the distortion which any map has) is what makes a globe so appealing. Then there's just the simple good feeling of being able to directly hold it in your hand, like a cricket ball, and to be able to directly span off distances with finger and thumb. The "2D monitor universe" has taken away our sense of 3D touch when it comes to information processing.
The idea of a programmable globe surface is fantastic.

There is a programmable globe surface available (probably not at consumer prices, though) called "Science on a Sphere" (spherical projection surface, multiple projectors). Several museums have them.

8/2/2012 6:45 PM EDT
Thanks for pointing that out; I was not aware of such being available.
Science on a Sphere has its own site (easily found by googling): http://sos.noaa.gov/What_is_SOS/index.html
The sphere is 68" (~173cm) in diameter and seems to be basically a screen for eight ("the projectors are at the corners of a virtual box with the sphere at the center") external projectors controlled by a computer.
(Using external projectors is probably more practical in set up and maintenance and more cost effective, but such would have disadvantages in terms of sensitivity to vibration of the screen or projector and blocking the path between screen and projector.)
The available datasets are biased toward weather/climate (as one would expect from being provided by NOAA), but there is an "Evolution of the Moon" dataset from NASA (in "Extras") and a collection of "Astronomy" datasets.

At an estimated $44k for just the components, that would be a bit outside of "consumer prices". :-)
It seems only four projectors are required (and a spare is recommended)--at $4.5k each, this is the majority of the cost. (The sphere is $8,310; the computer is $2,500 and a spare is recommended [so $5k].)

The other cool factoid about San Marino is that it is big enough to have had a Formula 1 Grand Prix but not big enough to have a track! :-P

You might need a slightly bigger office to fit this one but, the globe that you want is hanging in the Tokyo Science museum: http://tokyotek.com/geo-cosmos-gigantic-globe-oled-display-video/
