The Fire at Notre Dame Cathedral

This was not what I was going to write about today, but the news of the fire that ravaged Notre Dame yesterday rightly dominated the news yesterday and this morning. However, while I found multiple articles dealing with photographic evidence of the damage, I did not see many that detailed the fire from an illustrative or diagrammatic standpoint.

Thankfully, the New York Times did just that. They posted an article that deals specifically with the fire. It includes this set of small multiples that shows the progression along the roof and spire.

The article also includes a nice diagram explaining how the fire was focused on the cathedral’s attic. That explains some of the imagery from this morning that shows combustible materials like the pews and pulpit on the stone floor fully intact. And that provides hope the overall building can be saved, as French officials are indicating today.

Demanding the Impossible

The key problem in the Brexit deal remains what to do with the Irish border. In essence, the UK faces the same trilemma it has since the beginning. It wants three things it cannot have at the same time: exiting the EU single market and customs union, so it can create a free and independent trade policy; no hard border between Ireland and Northern Ireland, per the Good Friday Agreement that ended the Troubles; and territorial integrity, i.e. no hard border between Northern Ireland and the rest of the UK in the Irish Sea.

Essentially, the UK can choose two of these three options. Below, I have attempted to show how they relate and what the result is once two of the options have been chosen.

Building the Wall

Or at least a portion that was already funded back in March. If it was, in fact, a wall.

This morning it appears as if President Trump will not scupper the funding agreement. It includes far less than the $5.7 billion he demanded, but do not forget back in March, Congress appropriated funds to construct barriers, not walls in Texas.

This piece from the Washington Post looks at those plans and details how wall-like or not these border installations are. (Spoiler: semi.) The screenshot below illustrates the levee fencing would work.

Whatever happened to "Tear down this wall"? — Whatever happened to “Tear down this wall”?

But the piece also includes some really nice maps and aerial shots, also seen above, of where these border enhancements will be constructed.

Overall it is just a really informative and enjoyable piece with several graphical elements.

But whether this is a wall, I will leave that up to you.

Walnut Pancakes in Space

One of the really neat things about space exploration has been the New Horizons probe that raced past Pluto, giving us the image of the now famous heart shape on the dwarf planet. But as it raced past a Kuiper Belt object named Ultima Thule on New Year’s, we received some tantalising first images of a snowman in space. Basically, two spheroid bodies fused together like a snowman or a peanut.

Except it’s not.

It probably doesn't taste like a walnut pancake, though… — It probably doesn’t taste like a walnut pancake, though…

This is a fascinating graphic produced by the science research teams that show how the latest downloaded photographs from New Horizons—it will take many more months for the full set—show Ultima Thule is not very snowman-like in its shape. Instead, it is far flatter and more, in their words, shaped like a dented walnut and a pancake.

The article has some additional material that show how that spin axis changes the view. They are short videos, but if you are interested in space things, it is neat to see. We are accustomed to seeing spherical objects in orbit around the sun. Not pancakes.

Arctic Chill

The Arctic air mass that has frozen the Midwest continues to spread and so today will be a tad chilly in Philadelphia. Yesterday, however, the Guardian had a piece that used data from NASA to show how the air masses over the Northern Hemisphere have been disturbed by unusually warm air.

One theory to how this all works is that the reduced polar sea ice means water absorbs summer heat instead of being locked in the ice. But then that heat is basically released come winter. (I’m oversimplifying this.) That warms the air, which disturbs the polar vortex. As the Guardian then explains, the destabilised air mass can wobble and spill some of its frigid air down into the lower latitudes. (It takes a little while because the polar vortex is in the upper atmosphere and the air needs to sink to the ground.)

Point is, bundle up and stay warm.

The Atom

We made it to the end of the week, everyone. And that is worth celebrating. Today’s post is for all the scientists out there and anyone who has ever been interested in the atom. You know, the little things that make up matter. xkcd put together a chronological history of several different models of the atom that attempt to explain its structure.

What’s Next, Brexit?

A no confidence vote on Theresa May’s government, that’s what.

For those not familiar with parliamentary democracies, basically a no confidence vote is held when a substantial number of members of parliament have just that, no confidence, in the government of the day. The legislative body then votes and if the government wins, the government stays in power. If the government loses, typically, though not always, a new election is held to create a distribution of seats—it’s thought—that will yield a government that can hold the confidence. (There really is not an analogy for this in the US government that I can think of.)

To be fair, nobody really expects May’s government to collapse this afternoon. The Tories and her Democratic Unionist Party (a small Northern Irish party supporting the government) do not want to hold new elections nor do they want to give the Leader of the Opposition, Jeremy Corbyn, the chance to form his own government as much as they might despise May and her Brexit deal. So in all likelihood May survives by a dozen or so votes. On the other hand, the result yesterday was surprising in its scale, so could twenty or so of the 118 Tories who voted no vote against May? Possibly.

So then what next? Thankfully the Guardian put together two calendars showing just what happens and, crucially, in the context of how much time remains until the UK crashes out of the EU.

In case she wins, as we expect.

It still doesn't leave a lot of time to figure out what to do. — It still doesn’t leave a lot of time to figure out what to do.

If she loses, which is possible, but unlikely.

The UK would have even less time in this scenario.

The key thing to note is that the election campaign would eat up most of the time left and leave the UK very little time to do anything but ask the EU for an extension.

These are two small, but really nicely done graphics.

The Brexit Deal Vote

Today’s (one of) the day(s). For those of you who haven’t followed Brexit, the British Parliament will vote this evening on whether to accept the deal Prime Minister Theresa May negotiated with the European Union…or not. And if not, well, the government now only has three—instead of the original 21—days to figure out a Plan B.

Of course this vote is only happening today because the government punted back in December when it was clear they were going to suffer a substantial loss. And back then, the BBC prepared this article about Brexit, where it was and where it was going. Funny thing is, after a month, not much has changed.

The screenshot below is of the process. As I noted above, the most critical change is that the government no longer has 21 business days to figure out what’s next. So instead of, to use the American football phrase, running out the clock, May will have to come up with something and present it to Parliament before 29 March, the day the UK leaves by statute.

I think the thing missing from the graphic is the chaos that happens if the deal is rejected. And while that may have been far from clearly the most obvious result two and a half years ago, it is now. And Parliament is scheduled to start voting around 19.00 GMT, or 14.00 EST for those of us on the East Coast or 13.00 CST for those of you in the Midwest.

New Plans for Old Subways

The New Yorkers among my readers know about the whole planned shutdown of the L train for repairs owing to Hurricane Sandy (tangentially mentioned in the graphic I commented upon yesterday). For those of you who don’t know, basically the salt water from the storm seriously damaged the tunnels and a whole lot of work needs to be done to repair them. The plan was that a segment of the line would be shut down, to no obvious insignificance to commuters along the route, and it would reopen in a year and a half.

Then the state governor realised that might be bad optics and since he controls the agency running the New York subway system, he cancelled the shutdown so engineers can look at a different type of design.

I love pieces like this one from the New York Times. They are not crazy and wide-ranging, instead we have illustrations to compare the plans. They do a really nice job complementing the story without overwhelming it.

Plus, I’m a sucker for train and infrastructure stories.

Pulling Gene-ies Out of Bottles

I don’t always get to share more illustrative diagrams that explain things, but that’s what we have today from the Economist. It illustrated the concept of a gene drive by which a gene modified in one chromosome then modifies the remaining chromosome to insert itself there. Consequently it stands an almost 100% chance of being passed onto the subsequent generation.

Naturally this means great things for removing, say, mosquito-born diseases from populations as the gene drives can be used to ultimately eliminate the population. But of course, should we be doing this? Regardless, we have a graphic from the Economist.

It makes nice use of a small mosquito icon to show how engineered mosquitos can take over the population from wild-type. The graphic does a nice job showing the generational effect with the light blue wild-type disappearing. But I wonder if more could not be said about the actual gene drive itself. Of course, it could be that they simplified the process substantially to make it accessible to the audience.
