It’s Friday, everybody, and that means we all made it to the end of the week.
As a millennial, I was surprised to learn that my mobile can actually be used to make telephonic calls. Phone calls, as they are often known, are like direct messages or text messages, but made without cat gifs or memes. And your voice cannot be filtered. It seems a #primitive way of communicating.
But thanks to xkcd, we can see how, using one person as a sample, the types of these phone calls have varied over the years.
Happy Friday, everybody. We made it to week’s end. But wouldn’t you know it? Millennials are still terrible. Admittedly this piece is over a year old, but I could not remember ever seeing it before.
If you do not recall, last year there was a debate about the spending habits of millennials and why they are not out there buying homes and properties. The point was that we waste our money on experiences like expensive coffees and, most specifically, avocado toast. So amidst all this, the BBC decided to look at how many pieces of avocado toast would be needed to purchase an apartment in 10 global cities. Neither Philadelphia nor Chicago were on that list, but New York is.
Ultimately, I have never had avocado toast. But it sounds pretty good. But I find it a stretch to think the reason I do not own a home is because I am trying to eat 12,135 slices of avocado toast.
Happy Friday, all. I’ve been busy preparing for a trip to Boston next week where I’ll continue to research my family’s history. But family trees and generational relationships between cousins can be confusing. Over at xkcd, however, it turns out the in-law relationships are more confusing.
Everyone is probably familiar with Venice, slowly sinking below the Adriatic. But, did you know the city of Jakarta, Indonesia is also sinking?
The BBC published an informative article about the city’s looming problem and the piece includes several nice graphics. The screenshot below is an interactive timeline of the amount of subsidence, or sinking, in the the Jakarta region. It’s been notably worst along the coast. But the striking part are the forecasts for 2025 and 2050 that place the city in danger.
Photography of the scale of the subsidence feature throughout the story. And about halfway through is a nice motion graphic piece that attempts to explain the sinking. I am not certain it is the best graphic, after all it references two US NBA stars and I wonder how well known they are. (Whereas everyone clearly knows who David Ortiz is.)
I was aware of Jakarta’s peril, but until reading this article, I had not realised just how imperiled the city really is.

I like to think that becoming a good designer requires lots of work. And that means different types of work. Work pushing you to learn new skills. So this graphic by Jessica Hagy over on Indexed makes perfect sense. How good you at something ties into how much you work at it.
For those of my readers in Europe, Africa, Asia, Australia, and South America, you are in for a treat tonight as you get to experience the longest lunar eclipse of the year. For those of us in North America, i.e. Canada, the United States, and Mexico, we get nothing.
So for a reminder, we turn to this nice piece from Vox that explains a lunar eclipse and why they are not as common as one might expect.
The piece uses illustrations like these from Vox and supplements them with graphics from NASA. The whole piece is worth a read, especially if you enjoy space things.
Enjoy your Friday, and if you live anywhere but North America, enjoy your lunar eclipse tonight.
Yesterday, space nerds were alerted to the news that 12 new moons have been discovered in orbit of Jupiter. These are much smaller than Jupiter’s moon Ganymede, which is the largest moon in the Solar System and is larger than even Mercury. The point is that there are almost certainly no Ganymede-esque moons orbiting Jupiter that remain undiscovered.
But despite their small size, these moons do have some interesting features, as the article I read in the Guardian pointed out. The most interesting is the orbit of the moons. In general, Jovian moons orbit either prograde, i.e. with the orbit of Jupiter, or retrograde, i.e. against the orbit of Jupiter. The two inner moons discovered are prograde and nine of the other 12 are in an outer orbit of retrograde moons. But Valetudo, the 12th, which orbits in the retrograde group, actually orbits in a prograde fashion. The graphic below from the Carnegie Science Institute does a pretty good job of showing this.
Ultimately this means that at some point in the future, Valetudo will slam head-on collision style with another Jovian moon. And reportedly that will be so intense we will be able to see it from Earth. Bangin’. Catch is that it will not likely happen anytime soon.
As for the graphic above, I am of two minds. I generally like the use of colour. The bright green contrasts starkly against the red—though it should be pointed out it would fail a red-green colour blindness test. And then the interesting, but admittedly less interesting prograde and previously discovered Galilean moons are in more muted blues and purples, which puts them further into the background. It works nicely as a complete package.
But should it be on a deep blue background? Lots of space visualisations use black backgrounds, including mywork and the workofothers. But sometimes work that uses a white or otherwise light background could more clearly show things like orbits. It is difficult to say with certainty because of the lack of a light background for comparison’s sake.
The other thing that gets to me is the viewing angle of the orbits. Clearly we are looking neither dead-on nor from high above. And that makes it a bit more difficult to compare orbits. Of course these might not all be on the same plane because orbits are in three-dimensional space. But if the orbits were all shown from above, it would certainly aid with problems of foreshortening.
All in all, though, I shan’t complain because we have more moons in the Solar System. And who knows how many more smaller moons both Jupiter and Saturn have.

Well, football is not coming home. But the World Cup continues. And should we get another final match tied at the end of extra time, that means penalty shoot outs. Thankfully, the Economist did a nice job detailing the success rates on goal by placement of the ball.
The only thing I am unsure about is whether the dots represent the actual placement or just positioning within the aggregate zone. The colours work well together and the graphic of the goal is not overpowering.

For much of the last two weeks the world has followed the drama unfolding in Thailand, where a youth football team has been trapped underground in a partially flooded cave complex. This weekend, rescuers, who had overcome a daunting challenge of simply finding them, began extracting the boys. And this graphic from the BBC shows just how challenging their extraction will be.
In particular I like this map. It illustrates both the path of the cave, but also shows how uneven the interior structure is. It does that by showing select cross sections with a person to scale. Some parts are so small and narrow that people can barely squeeze through.

When I lived in Chicago, karaoke was definitely a thing I did. Billy Joel’s Piano Man was among the songs in my repertoire. And this Friday, well, we made it to another weekend. So raise a glass, toast Indexed, and forget about life for a while.
