Types of Nuclear Weapons

When I was in high school I began to listen to music. To find music. To find artists. A guy who owned and operated the store next to where I worked recommended David Bowie, that guy whose songs I had heard on Philly’s classic rock radio stations. Back in those days we still had record stores—not that I knew what a record was—and I found a few used CDs—now that kids today would know what a CD is. Over that summer, I picked up a lot of new music. But what struck me about this David Bowie guy is that Space Oddity, Tonight, and Heathen all sounded so different from each other. He was a great one. And while I’m certain there will be some graphic in the future about his timeline—how can there not—today I am going to follow up once more on the North Korean nuclear test after coming across this graphic from Reuters.

You will recall how last week I looked at a New York Times post that explained the differences between a few different types of nuclear weapons. Well, here Reuters illustrates those differences.

Did North Korea Test a Hydrogen Bomb?

Yesterday we looked at the sites and timeline of nuclear weapons tests. Today, however, as we learn more about North Korea’s hydrogen bomb test, some are wondering whether it really was a hydrogen bomb or something else. After all, there are different ways to build the bomb. Some suggest North Korea tested an atom bomb on steroids, more properly called boosted fission. Anyway, the New York Times does a nice job explaining the differences between the atom bomb, the hydrogen bomb, and how we can infer what North Korea tested from the calculated size of the blast.

Nuclear Tests

Last night, in the States’ time at least, North Korea purportedly tested a hydrogen bomb. How does this differ from their previous tests? Well, those were all nuclear fission bombs, this is a nuclear fusion bomb. (Admittedly, I am simplifying a lot here.) Hydrogen bombs, the H-bomb, are more powerful and more efficient in that they emit less radiation. They are still pretty bad news, though. That bit has not changed.

Anyway, the Washington Post put together a nice piece about nuclear weapons testing. The big feature piece is a map of test sites over time. What I really like about it, however, is that they chose to split the world at a different point—the Pacific Ocean opposite the Prime Meridian. I have occasionally argued for using such maps more often given the increasing relevance of Asia and the relative decline of Western Europe. So it is nice to see it put to good use here.

Details in Charts

Today we are looking at a smaller piece from the Washington Post. The graphic fits within an article about US stock prices. What the graphic does is show the total scale, i.e. starting the chart on the 0 axis, and then showing in detail the fluctuations near the maximum end of the scale. And yet all of this done as an inset graphic. It need not be a full-width graphic, because the data does not demand it.

Married Men

Sorry for not writing the last few weeks, but I was on a much needed holiday. But I’m back now. And first things first, one of my good mates got engaged whilst I was back in Philadelphia. And so in honour of that we have today’s piece.

As the graphic might hint, it’s about marriage. The piece dates from September of last year—2015 and I think I will have to get used to that for a few weeks—and looks at the demographics of marriage mostly in the United States. The chart above in particular looks at men that are married at every age by year, i.e. how many men aged 30 were married in 1960 versus 2013.

Trump’s Poll Ratings

The news this morning carried the latest polling data out of Iowa for the Republicans. And in that state, Ted Cruz now polls above Donald Trump. And so I wanted to share this post from the Economist last week that looks at how Trump rises every time he says something ridiculous. Could it just be that we should expect even more ridiculous this week?

More Mass Shootings Than Days in the Year

A week on from the San Bernadino shootings, I want to touch on the frequency of mass shootings in the United States. This chart from the Washington Post’s blog Wonkblog looks at when mass shootings occurred in the States. And as of  2 December, 355 shootings in 336 days. That’s more than one mass shooting per day. Clearly the only logical solution is to give Americans more guns.

Syria’s Refugees

We go from one crisis to another, as we go back to Syria. This piece from Bloomberg is very nicely designed and is almost entirely in black and white. We often think that because computer, everything needs to be in a rainbow of shiny, shiny colours. But here we have places where the designers smartly used patterns and smart labelling to avoid the need for colour.

Climate Change in Charts

So yesterday we reimagined a less-than-stellar BBC chart. Today, we look at a good chart from the BBC about climate change, timed to coincide with the start of the Paris climate talks. This comes from an article with six charts related to climate change, but it is the best in my mind.

The trend…not so good.
The trend…not so good.

Nothing but nice design here with the use of colour to highlight the top ten hottest and coldest years over the last 225+ years. But it really comes alive when animated and tells the story how those coldest years occurred at the beginning of the set and the hottest are among the most recent years.
