Perusing Wikileaks’ Cables

Wikileaks’ recent leak of U.S. State Department cables offers the student with a politics/geography interest an amazing glance into the role of U.S. diplomats. There are however, a lot of cables.

The Atlantic magazine has come up with an interesting way of perusing the information. Their Cablegate Roulette webpage puts up a random cable every time you press the “Load a new story” button.

What’s also nice is that they provide a sentence or two that gives the context of the cable so you don’t have to puzzle it out on your own.

The cable excerpts are brief, well written and quite informative about the political goings-on in different parts of the world. They could make an interesting supplement to the geography curriculum. The self-motivated student with a geography interest would find these quite fascinating because you have to have a basic knowledge of the world and recent history to understand what’s going on.

An example:

An executive with Kazakhstan’s national gas company has dinner with the U.S. ambassador at the Radisson hotel in Astana, the capital of Kazakhstan.

FROM: ASTANA, KAZAKHSTAN
TO: STATE DEPARTMENT
DATE: JANUARY 10, 2010

ΒΆ7. (S) The Ambassador asked if the corruption and infighting are worse now than before. Idenov paused, thought, and then replied, “No, not really. It’s business as usual.” Idenov brushed off a question if the current maneuverings are part of a succession struggle. “Of course not. It’s too early for that. As it’s always been, it’s about big money. Capitalism — you call it market economy — means huge money. Listen, almost everyone at the top is confused. They’re confused by their Soviet mentality. They’re confused by the corrupt excesses of capitalism. ‘If Goldman Sachs executives can make $50 million a year and then run America’s economy in Washington, what’s so different about what we do?’ they ask.”

Water for life; for civilization

This nighttime photograph of the Nile River and its delta from the International Space Station beautifully illustrate the importance of water for life and civilization. The city of Cairo is at the neck of the delta; the brighter spot where the distributaries diverge.

Spaceflight Now has other really cool photos. Bad Astronomy has an interesting post on the logistics of this particular photo, while Heather Pringle has a very interesting post on how the desert may have aided the ancient Egyptian’s civilization.

Rearranging the map

What if you exchanged countries based on population for land area? So China, which is the most populous country would take the place of Russia, which has the largest area. It would create the intriguing map below (from the wonderful blog, Strange Maps).

Exploring Space: Extrasolar planets

Notice the planet in the lower right corner? (Image from the Hubble Space Telescope via Wikipedia).

One of the neatest developments in recent space exploration has been the accelerating discovery of planets orbiting other stars. Other stars are just so far away that it’s insanely difficult to see anything orbiting them. Also, the stars can be much brighter, a billion times even, than the planets. So, in the beginning, they could just identify the largest of planets, Jupiter sized and bigger, because of they way they make their stars wobble, but this and other techniques have gotten better and better and now we’re looking at smaller and smaller planets, getting down to Earth sized objects.

One of my students, in investigating modern space exploration, found The Extrasolar Planets Encyclopaedia, which is pretty sweet because it keeps a running tally of planets found outside our solar system. When he found it last week the number was 502, now it’s 504. The site also has a long list of the ground and space based projects looking for extrasolar planets, which demonstrates how active the field is today.

Letter from a dying explorer

While discussing polar exploration, I mentioned the story of Amundsen and Scott’s race for the south pole. The fascinating blog, Letters of Note, has Scott’s last letter, written bit by bit, on the ice, to his wife back home. It starts, “To: my widow.”

P.S. Letters of Note is a great resource for examples of great letter writing.

God, Glory and GOLD: but why gold?

NPR’s Planet Money has a nice story on why gold is used for money. They take the entire periodic table of elements and eliminate the ones that don’t work because they’re too reactive, a gas, too common, or too toxic. You’re left with five precious metals, rhodium, palladium, silver, platinum and gold, but only one of them has a low enough melting temperature so that it can be worked easily and is not ridiculously rare.

Also, Tony Clayton has a wonderful webpage on Metals Used in Coins and Medals. It has some fascinating details about the history of these metals and their alloys in coinage. For example, “In Old English the Latin word aes was rendered as brass, thus the use of the word brass to mean money still found today, especially in Northern England. “
