The Sinking of the Vasa

In 1628, Sweden launched one of its largest and most powerful warships not just in Sweden, but in all of Europe. She was to participate in the wars with Poland and Lithuania as Sweden sought to expand her growing empire. After two years of construction in Stockholm’s naval yard she set sail into a calm day with a light breeze.

After a strong gust pushed her hard to port, she righted herself and continued to set sail to a fortress to load 300 troops for the war. But only 20 minutes into her maiden voyage, a second gust of wind pushed her again hard to port so much so that water began to flood in via her open lower gunports. As the continued to rush in, she never righted herself and sank, not to be recovered for 300 years.

The recovery itself is a great story, but the question was why did she sink? This model in the large Vasa museum, built to host the recovered and preserved ship, shows just how dangerously she was designed. Take careful note of the faint blue waves signifying the waterline of the ship and how close they are to the lower gunports.

The short takeaway is that the ship was top-heavy and she needed to be both wider and deeper to support her displacement. I like the model here, but my one complaint with it is the waterline. Even when I was standing in front of it, I did not notice the waves at first. A little bit more emphasis or paint, perhaps to show the water beneath the ship, would really help to convey just how little of the ship was below the waterline.

Farewell, Cassini

Today’s post is a sad post, hence why I did not run with it on Friday. But on Friday, we bid adieu to the little space probe that could, Cassini. This piece is not terribly heavy on the information design, but it does include one diagram—so it counts.

The BBC put together a piece reflecting on the Cassini mission, including its little lander Huygens. If you, like your author, are interested in space-y things, this article is worth the read.

Hurricane Winds

Irma swept the northern coast of Puerto Rico last night after devastating some of the Leeward Islands. What’s next? Well after the Turks and Caicos, Cuba, and the Bahamas we are probably looking at a Florida landfall. (Though in the last 24 hours the track has shifted ever eastward so Tampa Bay looks fine from a direct impact standpoint.)

Harvey was an exception in many ways because most deaths occur not from rainfall flooding, but from the storm surge. Basically a massive wave of water driven by low pressure and strong winds that is literally pushed ashore.

Now even though I just said that, I wanted to talk about the winds for a second. Why? Well it turns out that at 185mph, Irma has some of the strongest sustained winds ever recorded for an Atlantic hurricane. And 185mph winds, they can do quite a bit of damage. How much? Well for that we turn to this illustration from Vox.

Assuming the worst case scenario and Irma would strike just southwest of Miami, say Homestead or Key Largo, 185mph winds could do some damage to non-hurricane-safe buildings in a very large American city. And then there is the storm surge, which could be problematic for a city that is already struggling with rising tides. (Thanks, climate change.) The reason I say worst case is southwest of Miami is because hurricanes do most of the their damage—though certainly far from all of it—on their righthand side, which in a northward moving storm would be the eastern half.

The rest of the Vox piece does a nice job explaining Irma, its historic nature, and how it could be so dangerous. Worth a quick read, unless you live in Florida and then you should probably be packing up to evacuate.

North Korea’s Missile Programme

Another week, another batch of news and posturing from North Korea. So I was delighted to see last week a post from Politico exploring the history of the North Korean missile programme with data visualisation.

Shall we play a game?
Shall we play a game?

This kind of maps are my favourite for these types of stories. So often people get locked into this idea of a Mercator or Robinson projection and lines moving right/left or east/west on a map. Instead the world is a globe and the missiles or airplanes or birds or whatever will fly in circles over the poles if it’s easier.

Where Trump Has Travelled

Okay, not entirely. But Bloomberg put together a solid series of graphics tracking not the travels of Donald Trump, but his private aircraft. But that information can serve as a rough proxy for Trump’s travels. But the data is not complete—Russia is missing from the map though he has visited the country for business.

North Korea’s Latest Missile Test

If you missed it—and these days that is entirely possible—over the weekend, North Korea tested yet another missile. It did land very far away as it fell just off the coast of North Korea near Russia.

But it did travel far enough away to be of concern. Why? Well, this print graphic from the New York Times does a great job showing what that missile test really tested.

I want to end on a geography lesson for Attorney General Jeff Sessions. Those little dots in the upper right part of the circle? Those are the Aleutian Islands. They are like that island in the Pacific known as Oahu, which is part of the state of Hawaii. The Aleutians are part of the state of Alaska, which is, you know, one of the 50 states. Just trying to help you out, sir. So if you ask why we care about defending those islands in the Pacific, well now you know.

Comey Contradictions

Last week was crazy, am I right? But one thing that made complete sense was President Trump’s rationale for firing FBI Director James Comey.

And to prove just how much of a logical, straight-line reasoning there was we have this graphic from Sunday’s edition of the New York Times.

The complete graphic.
The complete graphic.

Okay, so maybe that is not quite such a straight line.

I want to excerpt the bottom half because it clearly shows the contradictions—the top half merely establishes the statements to be contradicted.

Yep. It's all very clear.
Yep. It’s all very clear.

I particularly like the use of the blue lines and bold set type to distinguish from the linear narrative of the administration. But what makes it work are the concisely written blurbs that detail just what the contradiction was.

The Meaning of Macron and Le Pen.

Well there you have it. Macron and Le Pen are moving on to round two of the French presidential election. Now, I have two things I want to address regarding the election. Today’s post looks at the meaning of the result and tomorrow’s will be about how that result was displayed.

Quartz did a really nice job outlining the likeliest outcomes, where the candidates stand, and then the initial polling for a round two head-to-head. And they did it all in one graphic.

What do the outcomes mean?
What do the outcomes mean?

I might not like the style of the icons—a a dollar sign emoji for a country that uses the Euro?—but the concept works well. But the best part is the brief synopsis to the right that describes the meaning of that particular outcome.

The Mother Of All Bombs

Yesterday the United States dropped a GBU.43 on a cave complex in eastern Afghanistan. The bomb is better known by its nickname MOAB, Mother Of All Bombs. But just how does the GBU.43 compare to some of the more common—and not so common—weapons in the US arsenal?

What we do know is that yesterday was the detonation of the largest non-nuclear bomb in warfare. We do have an even larger conventional weapon called the Massive Ordnance Penetrator—phrasing?—but its size and warhead are not as large as the MOAB. MOP is instead intended to be used as a super bunker buster.

An Update on Trump-Russia Ties

Between travelling and being ill, I apologise for a lack of posting the last week or two. But as promised, we are back with a small update to the Trump–Russia ties. It turns out that shortly before the Syria air strikes, news broke that Jared Kushner omitted dozens of contacts with foreigners on his security clearance form. One, of course, is Russian ambassador Sergey Kislyak. But the other was Sergey Gorkov, who runs Vnesheonombank, which is a bank owned by the Russian government, which is obviously headed by Vladimir Putin. Both Gorkov and Putin share a second tie as they were both trained by the KGB/FSB.

The new link is the connection between Kushner and Gorkov

There is also news out of the UK today, via the Guardian, that British and other European intelligence agencies began, in summer 2015, to note contacts between Russian agents and persons of interest and people within the Trump campaign. And these European agencies were the ones that alerted American agencies, because American agencies are not allowed to collect intelligence on American citizens. More smoke and people who saw it earlier than we previously knew.
