    This video is a collaboration with Aatish Bhatia about how to see the COVID-19 tipping point - we present a better way to graph COVID-19 coronavirus cases using a logarithmic scale in "phase space" - plotting the growth rate against the cumulative cases, rather than either of these against time.

    @minutephysics, I'm afraid you have a SERIOUS error here. What you are plotting is log(dy/dt) vs. log(y), so a straight line means log(dy/dt) = k*log(y), or dy/dt = y^k.
    Thus, y = exp(integral of y^(k-1)*t). Since k < 1, this is an exponential only in form because as y grows the y^(k-1) term shrinks. If k = 0.5, then by the time there are a million cases, that term is 10^-5 of the value it started out with, assuming that k stayed constant.

    The Philippines is handling this horribly. We don't even know how our curve looks because the government won't conduct mass testing as adequate levels. And we're relaxing quarantine measures (after THREE MONTHS) before we've even seen any evidence that the curve is flattening.

    Can you revisit with current data and talk about why so many countries demonstrate exponential decay, but not USA? I also tried looking at new cases as ppm and displayed not as absolute numbers but rate of change. There appears to be a period "bump" approximately every 7 days. Is this real or a result of how data is collected?

    Lately, Republicans have been using the Total Cases statistic to argue that blue states have a worse response to this pandemic than red states.
    This video beautifully explains why changes in New Cases is the most relevant statistic if we want to talk about a given government's response to this pandemic.

      This does not make the same calculation the Minutephysics channel suggests, but it does show changes in new cases over time broken down by state.

    Two months later, and I'm still checking this graph on a daily basis. I've noticed that rather than a flat or smooth curve, my state's version of "leveling out" is a series of dips where the weekly infection rate is between 500 to 600 new cases, and peaks where it's in the upper 700's. That made me wonder: since going out to restock my fridge / pantry is unavoidable, is it safer to go out during a dip or a peak? Are there any epidemiologists who've worked this out with previous infectious diseases?

    The graph (and video) should be modified by doing a log plot of new reported deaths per million versus a log plot of total reported deaths per million. In the absence of that it is quite misleading and is virtually certain to lead to widespread misunderstanding.

  • m mandrewa
    m mandrewa 5 päivää sitten

    I like this a lot. It seems like a good idea.
    But where the heck is the follow-up?
    Since this important you should be updating it at least once a week. You don't have to do it yourself, just modify the intro, not the video, but the blub below the video, by posting a link to someone else that is doing this.

    • m mandrewa

      Ok, I've found it.

      The US fell off the line in the first half of April.
      And I believe that graph and the graph in this minutephysics video would be improved if it did a log/log plot of new reported deaths per million versus total reported deaths per million. As it is this plot falsely makes it appear as if many countries that are not doing well, like for instance Belgium, are doing very well, simply and only because they are small.

    well, I'm from china and now an American university student, and I stay hometown now, wait for maybe fall semester back. we all don't believe the real case turns to absolute 0, but from February everyone from Wuhan or outside travels to another place will be stayed at home 14 days to confirm(no matter you have any symptom)if you get COVID. and from February one family only got 2day once going out chance for buying some food. the government may or must hide some cases but in china what CCP(you remind this word)say, most Chinese will follow and do even they don't agree with a lot...
    so all people in China don't have any outside action from February, the Wuhan get "city lockdown"(you can't leave your city absolutely anyway) I can't trust the sudden fall of the case but the increase or we actually be lower than many countries I think...south Korea did something likely, they lock their country.
    I love America and for china not to the government lot, I love our people...some doctors work nearly 20 days and sleep totally less than 20hour to save people...that's a challenge to everyone

      @wojeff Ok thank you again. It me a few minutes to figure out what they were doing and to find the plot of new reported deaths versus total reported deaths.
      Here's the problem. Why not normalize the data?
      That is divide the numbers on each axis by the population of the country. That would make it possible to compare countries. As it is right now, it makes it appear that the United States is doing very badly, when this is largely an artifact of it being both the largest country plotted plus having more complete data.

    The one caveat and maybe most important is that confirmed cases is such an unreliable measure since countries have varying levels of testing and testing is inaccurate. I feel like a new number of deaths vs confirmed deaths graph would be a more realistic trend.

    • wojeff
      wojeff 10 päivää sitten

      That was addressed in the video. Counterpoint, you can't have deaths if you don't have cases (so grim!). They have done that for deaths here:

    Total bulls**t by another person infected with Digital Narcissism peddling unicorn feces. Nobel laureate Pro. Michael Levitt studied Covid case growth rates starting with Wuhan and showed that the reported growth rates never achieved "exponential" slope, used 2nd derivative standard, and this mistaken assumption was why Neil Ferguson's initial mortality estimates were pure bolux. Covid case growth rates are about as exponential as the hits on this web-page.

    COVID 19 ORIGINATED in USA. The virus was leaked from Fort Detrick, Maryland in July 2019. The bio-warfare lab was subsequently shutdown due to leakage. A substantial proportion of US flu cases were in fact covid19 cases. On 12 Mar 2020, CDC official had admitted that "some" flu cases in the US are COVID 19 cases. COVID 19 is spreading in US as early as August 2019, the gov just covers it up. The American athletes brought the virus to Wuhan when they participated in World Military Games.
