Science of COVID-19

July 21, 2020

It was Arthur C. Clarke, notable author, inventor and futurist, who’s quoted as saying, “Any sufficiently advanced technology is indistinguishable from magic.”

Very true indeed. We all take for granted technology these days that would baffle even the brightest minds of not-so-long ago. The little phone you carry around (and perhaps with which you’re reading this) is a prime example. We get mad at it when “the stupid thing isn’t working”, but you’d think about it differently if you considered the complexity of the underlying infrastructure that makes it all work. Imagine someone 50 years ago watching you take a picture with your iPhone. OK, fancy tiny camera… very cool. But not impossible. And then they watch you AirDrop™ that picture to the person next to you. That’d be nothing less than magic.

I’ve been around long enough to see true innovative technology arrive, explode onto the scene, and then slowly drift from relevance as newer, more advanced technology took over. For example, CDs. They appeared literally overnight (from a consumer point of view) and took over the world. They were, for a time… magic. And they have since drifted into obscurity.

One interesting thing in the early days of CDs was both the marketing and technology of what was called “oversampling”. There’s more to it than what I’m going to describe, but basically it was this – the laser that’s reading what’s on the surface of the disc has about a zillionth of a second to bounce itself off a particular spot and decide whether it’s a one or a zero. And it’s not always right. Since that’s happening 44,100 times per second, it’s not a huge deal if it gets it wrong once in a while. But, that depends how wrong… your music quality would tend to degrade, and if it’s data, it has to be perfect. Data inherently is stored with what are called “CheckSums” – that verify the integrity of the data. For example, a simple version might be that after every 1,000 bits, it tells you how many zeros there were. And also how many ones. If those two numbers don’t add up to 1,000… there was a problem, so read it again. Credit card numbers also have a built-in sanity check… VISA numbers start with 4, MasterCard with 5… but not just any random string of 15 digits after that will work. In fact, only one in ten.

But music isn’t stored that way… it’s just sample after sample. So what they did is this… they’d get the laser to sample each bit more than once. 2x oversample. 4x oversample. 8x oversample!! If 6 of 8 of those reads say it’s a one, go with that.

If this sounds just like adding more and more blades to your razor, you’re right. At some point, the diminishing returns no longer make sense. How many blades do you need to get a perfect shave? I don’t know, but I know that two blades are better than one. Four is perhaps better than three. But I’m not sure 27 blades on some 6-inch razor are better than 26.

With CDs, I once saw a model boasting 96x oversampling. Come on.

This all comes to mind when reading numerous articles about COVID-19 testing. Rates of false positives. Rates of false negatives. People who’ve tested negative then positive then negative then positive. Good tests, bad tests, expensive tests, cheap tests.

In some cases, it’s a threshold… you could have it, but not in a high enough concentration to test positive. This is exclusively a problem for asymptomatic cases; I have yet to read about a test that reports a false negative for someone with symptoms.

Just thinking out loud… it makes me wonder… what would happen if you treated testing the way those CD players used to it. Do 8 cheap tests on someone all at once… instead of a far more expensive single test whose failure rate is lower, but not zero. Like I said, just thinking out loud… but one path of managing this involves testing; lots of it. And if you form a triangle of “cheap, fast, accurate” and have to pick two at the expense of the third… perhaps “cheap and fast” is the angle to go with. This is just simple statistics… not magic.

The year 2010 was only 10 years ago, but wow, does it ever feel like a long time ago. That was when the Winter Olympics were here; the memorable Iginla to Crosby gold-winning goal… also the year I should’ve been generating and holding Bitcoins… but, who knew.

It was also the year of the Deepwater Horizon oil spill in the Gulf of Mexico. Notwithstanding the catastrophic uselessness with which British Petroleum managed their little “faux pas”, there was an interesting footnote to the whole thing… which was that the environmental impact was far less than people imagined.

Don’t misunderstand; it was brutal, among the worst environmental disasters in American history. Almost 5 million barrels of oil leaking into the water over a period of months. The impact was felt for years, and BP ended up paying close to $20 billion to make it right; the largest corporate settlement in U.S. history.

But that interesting footnote of a lesser impact was due to… microbes. Little bugs that actually ate the oil and broke it down. While there had been some talk of trying to infuse the water with some sort of oil-eating bugs, and arguments whether the benefits outweighed the risks… and perhaps some little tests to sanity check it all… well, in the midst of that, mother nature came along and provided its own version, on top of what the humans were throwing at it. And surprisingly successfully.

Over the last couple of years, a lot of research has been done with respect to microbes and bacteria that eat plastic. And really, by “eating”, we mean consuming it and breaking it down… literally bio-degrading landfill waste. There’s that huge 600,000 square-mile garbage patch swirling in the Pacific Ocean, halfway between California and Hawaii… which some people think will be there “forever’. It won’t be… far from it. For now, it keeps growing, because we keep adding to it. But one day, when man is no longer around, that thing will start shrinking on its own… a far cry from “forever”.

A few days ago, scientists announced finding a bacteria that oxidizes manganese…and there are other microbes that can create conditions on other metals, leading to their breakdown.

The summary of all this is not that we shouldn’t care about our planet and the environment… we certainly should, because we have to live in it, in the present. More importantly, our children and grand-children have to, as well.

But it’s sobering and reassuring to know that no matter how badly we screw it up, it’ll all fix itself in due course. Unfortunately, that due course is measured in glacial, geological time frames. A million years isn’t much to earth (.02% of its existence), but it’s a lot if we’re hoping humanity lasts that long. It’s good knowing our super-long-term problems have solutions. Now let’s work on the present-day ones.

July 15, 2020

I haven’t been in many actual fistfights in my life, but by far the most memorable one took place in the backseat of a car, where my very good friend and I took a scientific discussion to a whole new level.

This was on the very last leg of a long road-trip, so perhaps we were feeling a little stir-crazy, but what happened was this: We got into a discussion about The Universal Gas Constant which, using the conventional (and very convoluted) units, is generally agreed to be 8.31

More accurately, it’s 8.31446261815324, but you never need that many digits for these sorts of numbers. For example, Pi (π) is an irrational number, and goes on indefinitely… and there are people who love to memorize the first hundred or thousand or, in one case, more than 65,000 digits of it… but you only really need 39 significant digits of π to accurately calculate the circumference of the universe using the width of a hydrogen atom. The rest is just for show.

Anyway, in this case, my friend had written a test where the teacher had given some problems to solve, and told the students to assume the UGC was 8.32. I argued that’s just wrong. It can be 8.31 or 8.314 or 8.3144 or even 8.3145 if you round from after the 44… but there’s no version of proper rounding or significant digits that gets you to 8.32. You can not go from 8.3145 to 8.315 to 8.32… you just can’t.

The discussion turned violent after he suggested that for the purposes of that test, given it’s what the teacher imposed, it was right. And I argued that you can’t just create facts like that to make life easier and expect them to be correct. That very good friend is reading this, and he’s now a chemical engineer… so I’d be more than happy to hear an updated expert opinion…

Indeed, a more famous (and less violent) case of something similar was in Indiana, in 1897, when some guy tried to legislate Pi to be equal to 3. The guy had figured out some math that managed to squish a circle around a square “evenly”… and if you look at his math and his diagrams, they’re all obviously wrong, but if you subscribe to the idea that science or math is just an opinion, well… this certainly makes sense, and it certainly makes life easier. No more pesky irrational numbers. Looking at this guy’s math, if π were 3, then suddenly, the square root of two doesn’t need to be irrational either. While a good approximation for √2 is 99/70, his math showed how now it can be 100/70 – so much easier.

And indeed, this is the problem when you try to play with facts… which are, in fact, that… facts. Not opinions… that when you mess with them, you break everything else that’s associated with them. You can’t change the value of π or √2 without wrecking everything else. The reason it all holds together in the first place is because it’s not a fancy opinion. It’s facts… the same facts that define the laws of physics and the fabric of our universe.

Every once in a while, someone will publish something “proving” they’ve measured particles that exceed the speed of light. And instantly, the “Einstein was wrong”, “Science is just an opinion” crowd is all over it. It’s really painful to read those comment threads.

Once again, here’s the thing… particles exceeding the speed of light wouldn’t be one little thing; it’d destroy thousands of associated theories and dependencies upon which the world has relied for over 100 years. You can’t just undo facts.

And yet… one of the more baffling things going on these days is the idea, by some people, that science is just another opinion. Science offers us ideas, but so does the neighbour’s grandmother, who’s really good with tarot cards… and opinions are just opinions, so we should take both into account. Some doctors say vaccinations are good, but my neighbour’s grandmother’s step-sister’s nephew knows someone who got vaccinated, and then developed some rare form of cancer and died. Therefore, blahblahblah.

And today comes word that no longer will the CDC receive COVID-19 data directly from hospitals. Instead, it will all go to the White House, who will then decide what to dish out. The New York Times is quoted as saying, "[the] database that will receive new information is not open to the public, which could affect the work of scores of researchers, modelers and health officials who rely on C.D.C. data to make projections and crucial decisions."

Well… we will see how this all looks going forward. This shatters the confidence I have in the numbers I get from a source that directly gets them from the CDC… I have a bad feeling that this will feel like π being 3 and √2 being a rational number… because Trump wants it that way. Because Trump says so. Because Trump needs it to. Let’s just create the facts that will suit the narrative. And people will continue to get infected and die… in record numbers, and nothing will fit, and none of it will make sense… because, while you can change opinions, you can’t change fundamental facts. Why is this happening. How did we get here.

To three significant digits, The Universal Gas Constant is 8.31

And, like Donald Trump, both π and √2 are irrational. And while some things can’t change without disrupting the fabric of the universe, other things could… but choose not to.

Greetings from Whistler… where… good news! The pandemic is over! We went for a walk last night in the village… lots of strangers hanging out, having a great time… no social distancing needed! No masks! It’s amazing, eh… a short drive up Highway 99 and it’s a whole other world!

If you ever get depressed about Vancouver weather… and I’m guessing today is as good an example as any, because it can’t be too different from Whistler, where it’s pouring rain… you know, when you open up the Weather App and it’s just a long row of rainclouds for the next week… you know what I mean… ugh.

So… what you do… is check out the weather in San Pedro de Atacama… and pretend that’s our forecast. That’s the place I’ve previously mentioned where it never rains. All you’ll see is an endless row of smiling sunshine. Isn’t that great? Once in a while, a little cloud will show up 5 days from now, wrecking that perfect visual streak. Poor silly little cloud; it’s just lost. Soon, mommy and daddy cloud will find it and take it up north, to B.C., where it belongs.

Yeah, of course, you’re fooling yourself. But maybe it makes you feel a little better, albeit briefly.

Indeed, if you like sticking your head in the sand… it doesn’t need to be in the sand of the Chilean Atacama desert… it can be a lot closer… Florida or Georgia or any of the 50 minus 5 states where case counts are increasing daily. Or, apparently, it can be Whistler too.

One thing has become abundantly clear; this pandemic will not end – truly, end – until there is a vaccine.

There’s a whole other discussion that emerges from that; the vaccine will probably only be X% effective. Many people, especially south of the border where health is a political statement, will refuse that vaccine. So let’s say only Y% of the population gets vaccinated. You end up with X times Y percent of people who are immune, and certainly that number will be far less than what’s needed for herd immunity. And so, this damn little virus will persist… much like the ridiculous outbreaks of measles… for which there’s no reason, other than the insanity of anti-vaxxers. It actually does feel like making one stick their head in the sand. At least it's warm, and not raining.

What a beautiful day for a bike ride… so, off I went, on a long one.

Usually, these rides wind up down by the water somewhere… Spanish Banks, Kits, out by Science World, English Bay, Stanley Park. I always manage to wind up at one of them. Today, it was most of them. And certainly, almost always, Vanier Park –- that beautiful, wide-open green space behind the Planetarium. Back in the 90s, when I lived near Granville Island, I was there almost daily. I’d usually walk west from my place… sometimes so lost in thought, I’d suddenly (well, a few hours later) find myself at UBC and have to take a bus back home.

But Vanier Park… there were two reasons I loved that spot. One, my favourite bench (which is still there, overlooking the water) and two… Ray Bethell.

If that name doesn’t ring a bell, it’s about to… because if you were ever down there at some point over the last 40 years, you’ll almost certainly remember the guy whose kite flying was so out-of-this-word that it was hard to imagine that what you were seeing was actually real. The guy flying three kites at once; one from each hand, the third tied to his waist, all three synchronized and doing acrobatics that were hard to believe and astonishingly beautiful.

I got to know Ray pretty well back then, and I’d often stop and chat with him. In fact, when he passed away in December of 2018, I wrote a little bit about it… back in the days when I didn’t post much to Facebook, haha. You can read it here:

https://www.facebook.com/kemeny.ca/posts/10156384761247481

And so today, as I was riding around that corner that used to be his turf, I thought about an interesting aspect of his life; he was older than I am today when he picked up his first kite. He then lived another 38 years… where, over time, he simply became the best in the world. As I wrote in that piece, whether you’ve seen him doing his thing or not, go re-live some memories and/or prepare to be astonished. Just Google the name or find him on YouTube. The dark, leathery tan… the wide grin… the unique cap. A lot of tattoos, with a lot of stories to go with them. And, of course, the kites.

It just goes to show, sometimes you can teach an old dog new tricks. Ray himself had a most interesting life, an eclectic collection of jobs. It was after he retired that he took up kites… which led to sponsorships and world travel and a whole 2ⁿᵈ act of his life.

Especially for those from whom this pandemic has been a life pause/reset/restart… or, at least, has led to some sort of introspection that further leads to thinking “what next” -– there you go. It’s never too late to do something else… and to eventually be doing it far better than you ever imagined.

Day 99 – June 23, 2020

I’ve written before about how sometimes, new words are needed…. to capture an essence that’s only describable by a lengthy paragraph. It’s great to see that such words often already exist.

Here are a few:

Vemödalen: (noun) The frustration of photographing something amazing when thousands of identical photos already exist.

On the surface, this comes to mind when you’re at the Leaning Tower of Pisa or Niagara Falls or any other world-class tourist trap… I suppose these days it doesn’t matter; digital pictures cost nothing. But for those of us who’ve been around long enough to remember that pictures came in expensive packs of 24 or 36, it’s a different story. You used to put a lot of thought before pressing the shutter button. And once those pictures were taken, it was several days before you could see the results. As you might imagine, taking pictures of your food wasn’t really a thing. Neither was taking 150 selfies to get the perfect one. Photography is a totally different experience these days, one we take for granted. But there’s more depth to that definition, and it touches on the entire experience that ends up being encapsulated in that photograph. Especially in an aforementioned tourist trap… where we’re trying to capture something we’d hope is unique to us, but deep down you know you’re just one of the insignificant many trying to capture the same thing so many others have tried. It’s an interesting duality, trying to be unique in a sea of similarity.

Occhiolism: (noun) The awareness of the smallness of your perspective.

I’m a good example… I’m here, happy to share my thoughts, but I’m aware I have a unique point of view; it makes sense for me, and I can defend it to the death, but there are those who’ll disagree and have their own points. I can probably argue their sides too, because I often understand them; I just vehemently disagree with them. But I’m well-aware it’s my unique perspective… one that’s the result of my own life experiences… and if I were able to visualize that, perhaps snap a picture of it, no doubt I’d feel a bit of vemödalen… because there’s nothing so special about it.

Liberosis: (noun) The desire to care less about things.

Everyone has their list of what’s important and what isn’t. The tops and bottoms of those lists are easy to define, or at least… should be. Your close family, top of the list. The idiot who cut you off and caused your blood pressure to blow up and caused you to yell a profanity… near the bottom. It’s the stuff in the middle, the stuff that could go either way, that often confounds us. Maybe we end up worrying too much or wasting a lot of time on something that ultimately isn’t so important. I try to apply a rule… don’t spend more than N minutes right now on something that won’t matter in N months. Easier said than done, perhaps due to my occhiolism — and the inability to be truly objective.

Combining all three of those is a good summary of my thinking these days, as I watch the world in what could only be described as a bad movie script. The sort where the writer walks into the meeting with a potential producer, and is laughed out of the office, being told to either write something that’s truly real, or pure science-fiction/fantasy. You can’t have both. A president too narcissistic to see or care that he’s destroying the fabric of his country? A global pandemic that many people aren’t taking seriously? Come on man… why not throw in some out-of-control wildfires in Australia, a near nuclear war with Iran and, for a bit of extra seasoning and comic relief, murder hornets. Get real.

So here we are… I think like many of you, I shake my head at what I’m seeing around me and am frustrated that the people who are supposed to be responsible and in charge and making such a mess of it. It’s not a movie I’d like to see, let alone be a part of. This whole thing is certainly not playing out like a Hollywood movie; maybe one of those dark foreign films, with a lot of black-and-white cut scenes of the past, hallucinogenic, colourful dream sequences, and, of course, lots of fancy, obscure words. The whole thing sometimes adds up to a worthwhile experience. In this case though, when we’ve come to the conclusion that the movie sucks, we can’t just walk out.

One last word:

Énouement: (noun) The bittersweetness of having arrived in the future, seeing how things turn out, but not being able to tell your past self.

Yeah, let’s all learn that one… you think it’s relevant now… just wait a few years. Or maybe weeks.

Day 98 – June 22, 2020

The numbers don’t lie. They can be twisted into statistics, which certainly can… depending how you paint them. But the raw numbers don’t lie.

Cases per million

Tests per million

Deaths per million

Deaths per case

Deaths per test

This list of malleable statistics is informative, but at the end of the day, there are some hard numbers that make up what feeds all these different angles of looking at the same thing. In my opinion, when all is said and done, excess deaths will have to be the numbers that get broken down. Those are not difficult numbers to pin down. Every jurisdiction knows, or should know, how many people die every day, week or month. That’s easily compared to the same period last year, whether as raw numbers or as a percentage of the population. These little graphs are showing up all over the place, and, as expected, show bumps starting in March.

The retro-analysis of these numbers will yield results that will get argued about, but those arguments will start falling flat the year after a vaccine shows up and things are fully back to normal. Certainly, they’re not all COVID deaths… but once you weed through cases of people who avoided the hospital out of fear and things like that, there won’t be another explanation.

In the meantime, we can only gauge where we’re at with numbers we can try to make as current as possible. Test positive cases is one. Virus-attributable deaths is another. Yes, we’re not testing enough. Or, as The President might suggest, we’re testing too much. Yes, some old people would’ve died anyway. Or, believe it or not, some old people can survive common colds or flus. Arguments on both sides, for now… but it’ll be hard to dispute ultimate deaths.

One number that we’ve all gotten used to is now changing… which is the average age of test-positive cases. How serious that turns out to be remains to be seen, but a lot more younger people are getting this. It’s no real surprise the Florida is turning into its own micro-disaster zone. Their governor (falsely) announced the curve was flattened, and things should head back to normal. Now we’re seeing the effects of what happens when you do that. The message that hasn’t been hammered home enough seems to be that until this thing is gone, it’s here. It ain’t over till it’s over. And I suppose the one thing about the presentation of this virus that makes it so difficult is how it skirts the line of “very serious” and “no big deal” so effectively, catering to both sides who’ve chosen what to believe. It’s at least 40x more lethal than a common flu, but it’s not 1,000x worse.

You may have noticed that my graphs and data have changed. I’ve removed Italy and South Korea. Both have been there from the start, because the entire reason I started writing was to track the path we (Canada) were on, as compared to others. There’s no longer much to learn from those two, because in three months, we’ve clearly defined our own track, both nationally and provincially. Thank you Italy and South Korea for providing us with data with which to compare, and congratulations on flattening your curves effectively.

What’s left now is the U.S to compare against. There was a time we were following them lockstep; fortunately for us, that deviated a while back. But what’s going on south of the border is still very important to us, so I’ve not only kept the U.S., but I’ve also added in the same level of detail as the Canadian national and provincial data. I’ve also removed the Time To Double (TTD) of 2 and added a TTD of 20. Indeed, things have flattened beyond the initial crisis. But as we’re learning, things can change. Numbers don’t lie.

Day 94 – June 18, 2020

Everyone has heard of Schrödinger’s Cat, but there’s a subtlety to that famous experiment that needs to be clarified… which is… it’s not that when you look into the box, only then do you know whether the cat is alive or not. It’s that until you look into the box, the cat is both dead AND alive. If that has you scratching your head, it’s because of course it’s a non-sensical scenario.

The issue has to do with mapping behaviour in the quantum world… to our visible, relatable world. And I’m not talking about the pseudo-scientific vibration energy healing quantum whatever… I’m talking about actual quantum physics, where things work differently at the subatomic level… and one of those things is that some particles, which can exist in one of two states, seem to exist in both… until you observe them, at which point they pick a side. For example, an electron… it has two levels, spin-up or spin-down. When you observe the electron, you can tell which state it’s in. But until you look at it, it’s spinning both ways. Or the polarization of a single photon… vertical or horizontal. And until you observe it, both. In simpler terms, imagine a coin. You flip it, and it falls to the ground. Now try to imagine that until you look at it, it’s both heads and tails… but the moment you look at it, it’ll pick one or the other. Bizarre.

There are problems with this sort of interpretation, and it’s one of many… but the thing is, this behaviour does exist, and it’s the foundation of the science that takes advantage of quantum mechanics. In a typical computer, data is stored in bits… and each bit is a one or zero. In a quantum computer, you have a Qbit… which can be a one, a zero… or both, simultaneously. A simple example, in a normal computer, a Byte is 8 bits, which can represent 2⁸ different numbers (from 0 to 255). But if that is a QByte (8 Qbits), you could theoretically evaluate all 256 versions at once, which on the surface implies a computer 256 times faster. And now imagine there isn’t just one QByte… but many.

Schrödinger had a problem with that, and came up with his famous thought experiment… which led to years of arguments with the greatest minds of the day, like Einstein, Planck, Bohr and Heisenberg (the theoretical physicist, not the meth cook).

At the end of the day though, what’s clear is that while these are all interesting theoretical discussions, and quantum effects can be exploited down at that level, as baffling as the experiments are (and there are trivially simple experiments you can do to actually see quantum effects)… the real world just doesn’t work this way. The “alternative facts” model of reality doesn’t allow for two things to be true at once, as much as some people would hope. The world’s issues aren’t waiting around for us to observe them before they tip in one or the other direction.

At present, depending how you wish to observe it, you might interpret this pandemic to be over. Or, of course, you realize it’s still very much going… and we need to be cognizant of that and respect it. You can’t have it both ways, but this seems to be what’s going on, depending to whom you listen. Schrödinger’s virus.

"If you look, the numbers are very minuscule compared to what it was. It's dying out.” — said Donald Trump, this morning. “No, it’s not”, says everyone else.

I guess it’s a good thing we’re not all subatomic particles, waiting to tip one way or the other. It’s good that while we understand there are indeed two (or more) sides to every issue, many of those sides don’t actually exist on top of each other. There’s some certainty to the fact that we’re still in the midst of a pandemic, and there’s no version of political/pseudo-scientific hand-waving that’s going to change that… and we’ll see that in rising numbers as things open back up. Today, Canada went over 100,000 known cases. Let’s hope we’ve all learned something and stick with it… the idea was to get it under control, which, around here, we’ve done. The important thing is to keep it that way. Or we’ll have bigger problems than trying to figure out if some theoretical cat is dead or alive.

Day 92 – June 16, 2020

A little after 10am on the morning of December 17ᵗʰ, 1903, upon Kill Devil Hills in Kitty Hawk, North Carolina, Wilburn and Orville Wright flipped a coin. Orville won the toss, thus putting him in the historical category reserved for people like Neil Armstrong. Wilbur was the Buzz Aldrin of this metaphor. It’s incredible to think that it was only 66 years between that first powered flight that morning (4 flights that day, Orville and Wilbur alternating turns at the controls), and walking on the moon.

The Wright Brothers had built their flyer in Dayton, Ohio, and secretly moved it to the coast in October, where they rebuilt it and tinkered with it until it was ready. What’s interesting, and what, to me, is perhaps an even better argument against the possibility of time travel (at some point, I wrote about how’d you materialize in the middle of outer space because the earth will have moved — a lot — even if you only travel a tiny fraction of a second), is that when they flew that day, there were only 5 other witnesses. If time travel were possible, what a “time-tourist-destination” that would be. Kill Devil Hills would be covered with millions of people hoping to see this with their own eyes. I’d be one of them.

Indeed, if you were given a time machine, but you could only use it once… go somewhere in time, and then come back today… would you go backwards, as per above… or forward, to see that the future looks like?

To me, it’s a no-brainer… I can read about the past from many different points of view and build some understanding. But the future? Like how incredible would it be to see where things are at in 1,000 years? I’d be all over that. Which brings us to a great word of the day…

Ellipsism: (noun) A sadness that you’ll never be able to know how history will turn out.

I think that’s what I felt this morning reading a very interesting article in The Astrophysical Journal, which talks about another interesting “way-out-there” scientific topic: Life on other planets.

These guys did a lot of fancy math, based on some well-thought-out premises and assumptions, and came up with the number of civilizations in our Milky Way Galaxy capable of interstellar communication. That number turns out to be… 36. Plus 175 or minus 32… so, for sure, somewhere between 4 and 207. And take that “for sure” pretty lightly, because, at the end of the day, who the hell knows.

But man, would I love to know. As far as we know today, there’s almost certainly intelligent life out there. But what we also know, warp drives and other cool science-fiction technology notwithstanding, is that given the fabric of the universe, we may never know. Albert Einstein came up with some theories more than 100 years ago, and no one has managed to prove him wrong. Nobody is exceeding the speed of light anytime soon (ie, ever), so, at best, maybe a few radio communications… and we’ve been sending messages out, on purpose or not, for maybe 100 years. We’ve been listening too, but haven’t really heard much — with a few curious exceptions over the decades… unexplained, but not proof of anything. The best case scenario would be finding intelligent life 4.4 light years away, at our nearest star system (Alpha Centauri, made up of three stars and a bunch of planets). Many people have been listening in that direction, but we’ve heard nothing of interest.

It’s frustrating, because that’d the best case scenario, but it would still take almost a decade for a quick back and forth. And what would that even look like…

Us, in 2020: “Hello, hello, is there anybody out there….”

Aliens, in 2024: “⍝⌷⌿⍝⌵⍰⌼⌹⍊⍠⍏⍛⍘⍙⍎⍜⍁⍚⍎”

Us, 2029: “YES, HELLO!! WE ARE HUMANS ON EARTH!! WHAT’S UP!!”

Aliens, 2033: “⌻⌾⍊⌶⌸⍙⌷⍎⌺⍞⌶⍑⌼⍀⍁⍝⌺⍏⌾⍞⍝⍣⍰⍖⍚⍣⍏⍡⌼⌺⍋⍋⌼⍕⍏⌶⌶⍂⌻⍝⍟⍋⌽⍕⍏⍢⌿⌼⌵⍉⌼⍂⍖⍯⌵⍊⍣⌸⍡⌺⌮⌹⍡⌮⍝⍘⌸⍁⍒⌼⍏⌸⍒⍊⌺⍝⍋⍣⍁⍁⍢⍢⍕⌽⍏⍒⍏⍕⍯⍙⍚⍑⍟⍢⍣⍉⍡⍎⌹⌸⍁⍙⍙⌻⌸⌻⍚⌼⍑⍞⍘⌹⍉⍜⌼⍛⌽⍚⍒⌶⍜⍞⍒⍚⍚⍜⍙⌭⌻⌻⍖⍁⍟⍝⍊⌾⍚⍋⍖⌿⌽⍜⌭⌺⌭⍢⍜⍋⍕⍁⍑⍎⍋⍂⌼”

Us, 2037: (sigh)

And of course, the relevant and expected closing to an essay like this… how can we be searching for intelligent life out there when it’s already so difficult to find around here, ha ha. It’s interesting to think about, how on some alien planet a zillion miles away, aside from the scientific alien-searching intelligent brainy aliens, there are also stupid aliens. Conspiracy-theory-believing aliens. Aliens who won’t wear their version of a mask when out in public, during their alien pandemic. Yeah, that’s a zillion miles away. Much closer to home, 5,000 miles away, is Paris, France… where today, if the video I saw this morning is to be believed, things are “back to normal”. Crowded city streets, crowded cafés. I would’ve thought the video was from last Summer, except for the waiter wearing a mask. I am the first to say, I hope I’m wrong. I hope this doesn’t turn into a complete disaster. Paris had its worst of this in early April, and things look a lot better… but numbers are still going up, and we’ve already seen many examples where the “rush back to normal” is causing problems, so much so that lockdowns might have to happen again. In B.C., unlike many other places, slow and steady is winning the race. But with my daily dash of ellipsism, I really wish I knew how this is going to turn out.

Day 83 – June 7, 2020

Air travel has obviously been radically affected by this pandemic, but before everything went all to hell, it’s interesting to note that typically, there are so many planes (tens of thousands) flying around at any given moment, that it’d actually be impossible to ground them all; there’d be no room to park them. We caught a glimpse of that post 9/11 when, for a week, all air traffic over North America was stopped. Airports turned into giant parking lots — YVR was one of them, the taxiways and runways littered with an eclectic collection of livery. Another one of them was Gander, Newfoundland… a town with a population of around 10,000 people… and an airport that’s well-suited to emergencies, being the closest point between the U.S. and Europe… so when the call came in to every plane, “Get down now… anywhere… closest airport… NOW.” — every plane over the Atlantic, headed to the U.S… or every plane that had just departed, heading East… all of them set a course for Gander. The population of Gander almost doubled, for a week, when 38 planes carrying 6,700 people suddenly showed up.

And for a week, the air was clear — far clearer than it’d been for many decades, and it was an opportunity for scientists to gather data… to gather data that otherwise would never have been available. That was a very steep price to have paid for that data, one nobody would have wanted to pay. But since the opportunity presented itself, it obviously made sense to take advantage of it.

There’s the old saying… today is the first day of the rest of your life. And these days, until there’s a cure for this virus, today is also always the beginning of these rolling “5 to 14-day windows” where we get to see the after-effects of our activities.

We’ve come to learn a lot about the transmission of this virus, and how enclosed spaces for prolonged periods of time are a much bigger issue than being outdoors, being distant, and picking up the virus off a contaminated surface. Not to say that some of those things don’t pose a risk; they all might, but it differs… and effectively, the more exposed you are to the virus, both in time and volume, the worse it is.

The numerous protests going on around the world are a good example of these rolling windows, and everyone is keeping a close look at the outcome. It’s not an ideal experiment, but there’s plenty of data that’ll be made available; possibly very expensive data, as per the post-9/11 air quality numbers. In this case, the guinea pigs aren’t air particles… they’re human beings who decided to throw caution into the wind. While there are Covid-responsible ways of protesting… masks, outdoors, socially distanced… many people said to hell with it. We’ve of course seen many maskless crowded protests already anyway, so what’s the big deal?

Well — there will eventually be answers to that rhetorical question. George Floyd was murdered on May 25ᵗʰ, coming up now on two weeks. It’s hard to judge what effect the protests around the U.S. (and Canada) have had, especially south of the border where numbers weren’t slowing down to begin with. So, to be sure, they’re still rising… but are they rising faster than they otherwise might have? And to throw more variables into it, openings have been taking place in many different cities and states; how much is that contributing? Washington State was doing pretty well, but they had a significant spike a couple of days ago… a week after many new openings. Coincidence? Just a spike, not a trend? Time will tell.

Around here, time will tell as well — for now, it’s two straight days without real data… tomorrow’s update will backfill Saturday and Sunday.
