Last month the Washington Post published a nice article that detailed the deep water cooling system that the city of Toronto, Canada uses to keep itself cool. For the unfamiliar, deep water cooling at its simplest means sucking up very cold water from the bottom of a lake or ocean or wherever you can get very cold water, and then pumping that inland to absorb heat before cycling it back.
Of course, for the longer explanation—and what makes Toronto’s system different—you should read the article. And for our purposes it includes some nice illustrations that diagram just how that system works. The screenshot below captures the basic process I just described, but there are additional illustrations that do a great job showing just how the system works.
What I particularly enjoy about this style is how the illustrations of the building and similar are minimal and restrained. This allows the diagrammatic elements to come to the forefront, which is important to make the system understood.
I spent the better part of the last two weeks travelling and hanging out in the Berkshires and Connecticut River Valley in western Massachusetts. One of the coolest experiences was driving up the automobile route for Mt Greylock, the tallest point in Massachusetts.
Most of the drive itself was just regularly spectacular as the mid-morning sunlight hit the trees above the road, creating a warm yellow-orange light that bathed the route. But maybe about halfway or two-thirds of the way up, I rounded a bend in the road and came upon a clearing—and convenient pullover. The scene elicited an audible swear and not surprisingly I stopped the car to enjoy the scenery and take some photos.
Whilst there, I also noticed a small sign that, among other things diagrammed the cross section of Mt Greylock and points to the east and west. And I figured that would be a good way to start the week.
The sign uses an old map to illustrate the different rock layers that define the mountain. Marble, which is a soft rock, erodes during glaciation whereas schist, a hard rock, does not. And during the recent ice ages, when glaciers covered the area, most of the marble areas of the mountain range were eroded away, leaving just the sharp stony peaks of schist.

Of course the inside threat are those little bodies of coronavirus causing Covid-19. We cover them a lot here. But there are also threats from little bodies outside, way outside. Like asteroids impacting us. And that was the news yesterday when NASA announced improved data from a mission to the asteroid Bennu allowed it to refine its orbital model.
And we have reason to ever just so very slightly worry. Because there is a very slight chance that Bennu will impact Earth. In 2182. The New York Timesarticle where I read the news included a motion graphic produced by NASA to explain that the determining factor will be a near pass in 2135.
Essentially, the exact course Bennu takes as it passes Earth in 2135 will determine its path in 2182. But just a few slight variations could send it colliding into Earth. Though, to be clear, it’s only a 1-in-1750 chance.
NASA used the metaphor of keyholes to explain the concept. The potential orbits in 2135 function as keyholes and should Bennu pass into the right keyhole, it will setup a collision with Earth in 2182. Hence the use of little keyholes in the motion graphic that accompanied the article.
But who knows, if we’re lucky the United Federation of Planets will still be formed in 2161 and the starship Enterprise will gently nudge Bennu back into a non-threatening orbit.
Yesterday I mentioned more about revolutions, well today we’re talking about Mars, a planet that revolves around the Sun. Late last week scientists working with the InSight lander on the Red Planet published their findings. Turns out we need to rethink what we know about Mars.
First, the planet is probably much older than Earth. Mars’ composition also differs from Earth in some significant ways. InSight mapped the interior of Mars by studying the seismic waves (think like sound waves but through the inside of planets) of marsquakes.
The Wall Street Journal published a great article spelling out the findings in detail that is well worth the read. It also included some nice graphics helping to support the piece. The one I wanted to highlight, however, was a brilliant comparison of Mars to Earth.
Conceptually this is important, because many diagrams and graphics I’ve seen about these findings only detail the interior of Mars. But what makes Mars important is how it differs from Earth, and let’s be honest, how many of us remember our Earth science classes at school and can diagram out the interior of Earth?
And right here the designer compares the smaller—and now older—brother of Earth. Again, read the article for the details, but in short, some of the key findings are that the core is larger, but also lighter, than we thought. Our planet’s core differs because Earth has two parts: a solid and heavy ball of iron and nickel surrounded by a liquid core that spins. That spinning core creates the magnetic fields that protect our planet from the Sun and have kept our atmosphere intact. Mars doesn’t have that. And that’s in part because, given the core is larger than we thought, the mantle is smaller.
A smaller mantle means that certain materials couldn’t form that insulate the Earth’s core. So while Earth’s core has been prevented from cooling and slowing down, Mars was not. And so while it did have a magnetic field at one point, that slowing, cooling core slowly dissipated the magnetic field. That may be why the planet, once rich in water, now is a barren rock exposed to the Sun.
Again, this is a big deal in terms of planetary science. Consider that Earth and Mars are broadly made of the same materials that orbited the Sun billions of years ago. But Mars took those same ingredients and made itself into a very different planet. And now we know quite a good deal more about the Red Planet.
One last point to make about the graphic above. Again, many illustrations will increase the size of the crust to make it more visible. Here the designer chose to keep it more in proportion to the scale of the planets’ interiors. (Even though Mars’ crust is quite a bit thicker than Earth’s.) I think that’s important because it puts us into perspective. We can build monuments like the Pyramids that last thousands of years and dig bore holes miles deep and tunnel out connections through mountain ranges, but that also just scratches the surface of the crust. But that crust is the thinnest of shells over the mantle and cores of these planets.
That life began and took hold on Earth, on that thinnest of shells protected by a magnetic field because of a spinning molten core buried at the centre of the planet…something to think about sometimes.
For the last two days Philadelphia and much of the East Coast suffered from a heavy haze of smoke that blanketed the region. This wasn’t just any smoke, however, but smoke from the wildfires on the West Coast. This post isn’t about the wildfires, but rather something that exacerbated them. We are talking about the heat domes that formed earlier this summer. The ones that melted trolley cables in Portland.
This was a nice print graphic in the Guardian Weekly, a magazine to such I subscribe that had several articles about the domes.
It does a nice job of showing the main components of the story and sufficiently simplifying them to make them digestible. One quibble, however, is how in the second map how oddly specific the heat dome is depicted.
The first graphic in particular is more of an abstraction and simplified illustration. But here we have contours and shapes that seem to speak with precision about the location of this heat dome. It also contains shades of red that presumably indicate the severity of the heat.
There’s nothing wrong with that, but it stuck me as odd juxtaposed against the top illustration.

This is a piece I’ve been sitting on for a little while now, okay half a year now. There isn’t too much to it as it’s an illustration overlay on a satellite photo. But the graphic supports an article about the construction of a new roundabout in Philadelphia, coincidentally where I used to live.
That intersection is…tricky to navigate at best as a pedestrian because there are six and a half streets converging at the junction—I give a half to Arizona St because, well, you’ll see shortly. When I lived in the neighbourhood I saw several near accidents between vehicles and pedestrians and vehicles and cyclists. Anything to help improve the safety will be welcome. And that improvement is what the Philadelphia Inquirercovered back in January.
This definitely fits in the category of well done, small graphics. Not everything needs to be large and interactive. This does a great job by using transparency over the satellite image and layering illustration atop the photo.
Now if we could only restore the old rails on Trenton Ave to be some kind of tram/trolley or light rain corridor. Regardless, there are some good restaurants and drinks options in the neighbourhood, so maybe I’ll have to go investigate in person now that going out is an option again. You know, to a do a proper follow-up.
Last week I posted about an article in the BBC on the English ancestry of American president Joe Biden. And these types of article are a bit pro forma, famous person has an article about their personal ancestry with a family tree attached. Interestingly, this article did not, just the timeline I mentioned and a graphic as part of an aside on the declining self-identification as English-American.
And that, normally is it. Perhaps the article comes out with a few revisions upon the famous person’s marriage, birth of children, and more rarely death, but that is it. Yesterday, however, the BBC posted a follow-up article about an English family claiming kinship with Joe Biden. This article, however, included a family tree of sorts.
This isn’t a family tree in the traditional sense, I would argue it’s the sort of chart genealogists would use to highlight two parties’ relationship to their most recent common ancestor (MCRA). But this chart does something odd, it spaces out the generations inconsistently and so Joe Biden appears at the bottom, aligned with the grandchildren of Paul Harris, the man at the centre of the story.
If you compare the height/length of the lines linking the different generations you can see the lines on Biden’s side of the graphic are very long compared to those on the Harris’ side. This isn’t technically incorrect, but it muddies the water when it comes to understanding the generational differences. So I revisited the design below.
Here I dropped the photographs because, primarily, I don’t have access to them. But they also eat up valuable real estate and aren’t necessary to communicate the relationships. I kept the same distance between generations, which does a better job showing the relationship between Joe Biden and Paul Harris, who appear to be actual fifth cousins. Joe is clearly at a different level than that of Paul’s grandchildren.
I added some context with labelling the generational relationship. At the top we have William and James Biden, assuming they are brothers, listed as siblings. The next level down are first cousins, then second, &c. Beyond Paul, however, we have two additional generations that are removed from the same relationship level. This is where the confusing “once-removed” or “twice-removed” comes into play. One way to think of it is as the number of steps you need to take from, say, Paul’s grandchildren, to get to a common generational level. In their case two levels, hence the grandchildren are fifth cousins to Joe Biden, twice removed.
These types of charts are great to show narrow relationships. Because, if we assume that up until recently each of the generations depicted above had four or five children, that tree would be unwieldy at best to show the relationship between Paul’s family and Joe Biden. If you ever find yourself working on your family ancestry or history and need to show someone how you are related, this type of chart is a great tool.

In what feels like forever ago, I wrote about the trilemma facing the British government as it related to Brexit. Brexit presented Westminster with three choices, of which they could only make two as all three were, together, impossible. Once made, those two choices determined the outcome of Brexit. For better or worse, Prime Minister Boris Johnson made that decision.
We can apply the same trilemma system to Israel in relation to the circumstances of Israel and Palestine. I will skip the long history lesson here. Israel faces some tough decisions. I will also skip the critique of Israeli government policy over the last few decades that brought us to this point. Because here is where we are.
Israel needs to balance three things: the importance of being a representative democracy, of being a Jewish state, and of security control of Gaza and the West Bank for the security of Israel. Here is how that looks.
If Israel wants to remain an ethnically Jewish state—I’m going to also skip the discourse about Jewishness as an ethnicity, though I will point to Judaism as an ethnic religion as opposed to the other Abrahamic universal religions of Christianity and Islam—and it wants to be retain security control over Palestine, i.e. the Gaza Strip and the West Bank, you have what we have today.
If Israel wants to remain an ethnically Jewish state and it wants to be a representative democracy, you get the Two-State Solution. In that scenario, Palestine, again conceived as Gaza and the West Bank, becomes a fully-fledged independent and sovereign state. Israel remains Jewish and Palestine becomes Arab. But, Israel loses the ability to police and militarily control Gaza and the West Bank, instead relying on its newfound partners in the Palestinian Authority or whatever becomes the executive government of Palestine. This has long been the goal of Middle East peace plans, but over the last decade or so you hear Two-State Solution less and less frequently.
Finally, if Israel wants to be a representative democracy, in which case both Jewish citizens and Arab–Israelis and Palestinians all have the right to full political representation without reservations, e.g. the loyalty oath, and it wants to maintain security control over Gaza and the West Bank, you get something I don’t hear often discussed outside foreign policy circles: a non-Jewish, multi-ethnic Israel. Today Arab–Israelis and Palestinians nearly—if not already—outnumber Jewish Israelis. In a representative democracy, it would be near impossible to maintain an ethnically Jewish state in a county where the Jewish population is in the minority. Consequently, Israel would almost certainly cease being a Jewish state.
One can tinker around the edges, e.g. what are the borders of a Two-State Solution West Bank, but broadly the policy choices above determine the three outcomes.
The outstanding question remains, what future does Israel want?
Most of my readers know that I am a designer who works in all formats. But, I really love working in print. Colours, textures, and the physicality of it all. Give me a foil stamp or metallic ink any day.
Any American designer who’s ever worked for an overseas client or overseas designer who’s ever worked for an American client knows all about the US Letter vs A4 debate.
For those that don’t, the US (along with Canada, Mexico, and a very few other countries) use what we call letter size paper. The rest of the world uses A4, part of the ISO 216 international standard. A4 has some special properties that make it the superior choice in my opinion.
But this is a Friday, so we’re here for the lighter take. And for that we have a video by CCP Grey, who explains some of the properties of A4 and then provides a fascinating perspective on it all. It’s about nine minutes long for what it’s worth.
With Covid-19, one of the big challenges we face is the rapid mutations in the viral genetic code that have produced several beneficial—from the virus’ standpoint—adaptations. Several days ago the New York Times published a nice, illustrated piece that showed just what these mutations look like.
Of course, these were not just nice illustrations of protein molecules, but the screenshot below is of the code itself and you can see how just a few alterations can produce subtle, but impactful, effects.
In a biological sense, these mutations are nothing new. In fact, humanity wouldn’t be humanity but for mutations. Rather we are seeing evolution play out in front of our eyes—albeit eyes locked in the same household for nearly a year now—as the virus evolves adaptations better suited to spreading and surviving in a host population.
The piece includes several illustrations, but begins with an overall, simplified diagram of the virus and where its genetic code lies. And then breaks that code down similar to a stacked bar chart.
Designers identify where in the code the different mutations occur and the type of mutation. Later on in the piece we see a map of where this particular variant can be found.
I might come back to that map later, so I won’t comment too much on it here.
But I think this piece does a great job of showcasing just what we mean when we talk about virus mutations. It’s really just a beneficial slip up in the genetic alphabet.
