Yahoo article: Hell is Coming: Here is the Mathematical Proof

From the article:
Our model also tells us that the number of infected people was 400,000 on March 8th, 800,000 on March 11th, and 1.6 million on March 14th.

These calculations imply that the American death toll will be 12,800 on April 7th. To put that in perspective, yesterday, the total death toll in Italy was 3400 and 3000 in China.

snip

Except a few educated people, no one has any idea that there are already around 2 million infected people in America today and the American death toll will exceed 15,000 in just 24 days. If we don’t take strict measures, we will be reporting 1000 deaths per day in just 3 weeks.

18. The entire point of the OP
Mon Mar 23, 2020, 09:06 AM
Mar 2020

Yes it will. Humans don't do exponential math instinctively.

Think of it this way: There is a doubling rate. That is the essence of exponential math. His estimate is that the doubling rate is 3 days. This is borne out by the way the disease has progressed in every single venue where it has been observed.

The purpose of social distancing, lockdowns, and all the rest is to stretch the doubling rate. So instead of 3 days maybe it takes 4 or 5 or 6. Bear in mind that changing the doubling rate to half requires heroic measures. And it's still an exponential progression.

So here's the rub: Half the people who will ever get the disease will get it in the final doubling interval. Yes, it's a little more complicated than that because the disease is starved for new victims as it saturates the population, but that's still pretty close to what actually happens. Nine tenths of all the people who will ever get it will get it in the last two and a half doubling intervals.

His estimate, which is fairly sound, is that there are currently 2 million Americans who are infected. Out of a population of 350 million this is nowhere near saturation so the doubling can be expected to proceed apace. The only thing that is known to slow it down is starving the disease of new victims by isolation. Since the disease takes 24 days to run its course the effects of isolation only become noticeable after a few weeks.

That 2-week death toll he predicts is from people who are already sick. There is nothing we can do to stop it. We have a very large population and it is nowhere near saturation. His model is not alarmist; if anything it is conservative. It's just what exponential math does. It rolls along almost below the threshold of perception until blammo, it blows up in your face. We're not used to things that do that. We tend to assume things will progress linearly, with today looking more or less like yesterday and tomorrow looking more or less like today. But that's not how this will work. One day tomorrow will look like a mushroom cloud.

One day fairly soon.

You keep saying you don't believe the 12,000 figure but on what basis do you disbelieve it? Because I read the OP and the conclusion is inevitable given the assumptions, all of which are if anything conservative.

Does your intuition tell you it's not possible? Intuition doesn't work on exponential phenomena. Studies have shown our instinct is to predict things linearly. But this isn't linear. All exponential phenomena reach a point where they appear to explode. That is surprising the first few times it happens, but eventually you learn that for an exponential phenomenon that explosion is normal.

There are measurements which can be used to describe an epidemic. You plug them into the equation and it predicts -- correctly based on the exponential behavior -- what the phenomenon is likely to do in the future. This is all the OP has done. So far the pandemic has spread exponentially in every population where it has taken a foothold until it either saturated the population or was starved for more victims by aggressive containment measures.

But the 12,000 figure is based mostly on people who are already sick. The social distancing and shutting down measures aren't likely to reduce it much by that point. With luck, we can maybe stop it from turning into 100,000 ten days later. Those numbers are not sensationalized; they are a baseline. Expecting anything less is innumerate wishful thinking.

We're still nowhere near the daily amount to hit 12,000+ in two weeks. By Friday, we'll probably be at 1,200 dead. By next Tuesday, it's likely going to be around 2,500. And by April 7th, likely 4,000. But not over 12,000.

I'm sure, in two weeks, when we're nowhere near 12,000+ dead, you guys won't come back and apologize for being absolutely bonkers alarmist.

The US currently has 696. 143 so far today (141 yesterday).

There's zero evidence we're going to see the type of spike it'd take to meet that goal two weeks from today.

After tomorrow, to get to that point, we'll have to see 1,000+ die every day and we've seen no evidence we're even remotely close to that point.

Stop trying to minimize what is going on here.

The day is not finished, and we are past the prediction in the OP.

IT WAS LOW.

Again, I understand that people do not intuitively grasp how exponential growth works, but today's numbers were completely predictable two weeks ago, and the prediction of what day we would reach 12,000 was precisely accurate.

That would not be a "surge".

It is a simple projection of the current trend.

Since you don't understand the reality of how nature works in this regard, it's easier shown with pictures.

These are US cases so far:



An easier way to understand an exponential growth curve is to visualize it in logarithmic form. So point your reality-perceiving devices at this:



Do you see how that lines up?

Do you see how each tick on the vertical scale is a factor of 10?

What that means is that the time it takes to go from 10 to 100 is the same as it takes to go from 100 to 1000 which is the same as it takes to to from 1000 to 10000.

That is the reality, DI.

Moving from cases to deaths, you have to understand that deaths lag cases. In other words, it takes several days on average for people to go from being a case to a death.

Here it is on a linear scale:



Here it is on a logarithmic scale:



Do you know how to draw a straight line with a ruler?

Even if we are following a Gaussian curve, we have not yet hit an inflection point. We are nowhere near an inflection point.

I'm sorry to break it to you, but neither your "gut feel", nor Trump's for that matter, is a reflection of any "reality".

The prediction in the OP was absolutely balls-on accurate.

And it has been obviously accurate to anyone who can read a graph. The slope of the line remained pretty much straight from the time this article was posted.

I might have remembered to check it more often if I hadn't apparently caught the COVID-19 myself and started showing weird, but fortunately non life-threatening, symptoms around the 18th. One of my coworkers was among the first 100 people in Louisiana to test positive, and my odd little bout is perfectly timed to be a COVID infection I got from him around the 13th. Fortunately it got me in the hip joints (ouch, but not life threatening) instead of the lungs. All clear now. Can't be sure, since you can't get a test unless you're half dead with a fever, but I'm 99% sure that's what it was.

And yeah, math works, ain't it amazing.

But we are lacking so much data. I think even if the number infected is as predicted it’ll take awhile to reach the death rate discussed. Because, the US really does have great medical care...the catch is for those that can afford it, and when it’s not overwhelmed. For awhile we’ll be able to save a high percentage, but when the numbers skyrocket and facilities are overwhelmed and half the medical staffs are sick themselves... That’s when it’s going to get bad.
