    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.

      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.

      Roses are red violets are blue why does the Karen think covid-19 is just the ordinary flu

    5. Douglas Powell

      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.

      1. Paul T Sjordal 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.

    8. Jennifer Beveridge

      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.

    12. m mandrewa

      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.

      1. m mandrewa

        Ok, I've found it. See 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.

      Chinese data are fake

    25. 刘娅

      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 希望全世界所有国家的人民早日摆脱这场灾难(best wishes for all people around the world get rid of this disaster ASAP )

    26. Alexander Jackson

      Could you make another video with these sort of graphs, to show which countries are recovering well and which aren't? It's the best way I've seen so far.

    27. Eva Lam

      China is LYING !!!!

      1. karen

        That's true, the CCP has lied again and again, ten million people have died here, come and save us plz ,XD

    28. nitchvideo

      Here is a powerful source of understanding. and yes it is more help than the news or government in understanding

    29. John the Greek

      Don't want to shit on your parade but China is most likely lying. Great video though

    30. Freeda Peeple

      I was not expecting a cogent, clear, informative video, but that's what I got! Thanks!!

    31. Benjamin Genco

      I keep coming back to get the link to the chart, hoping the US marker is gonna plummet

      1. m mandrewa

        And I was right. I've tracked it down and the US data begins to fall off that line sometime in the first half of April.

      2. m mandrewa

        I'm pretty certain it has. This graph and video are from two months ago, when the American epidemic had just begun. In fact I'll bet the US data plummeted over a month ago, back in the first half of April.

    32. Jewelry Bag

      This is a media-manufactured plandemic to further destroy the middle class and create a monopolistic dystopia. More people die of smoking, heart disease and cancer than this virus but the elites control the media narrative and, consequently, are controlling the sheep. I am so pissed off

    33. wojeff

      March 24: this video was filmed March 25: highest exponential growth point in US March 26: start of exponential growth decline in US March 27: this video premiered

    34. Eugenia Sum

      They didn’t include Taiwan tho

      1. wojeff

        I think emphasis was shown on countries with significant case totals. It's there and now in the main view too (good work Taiwan!)!

    35. Bern Metro

      Please provide a updated version; same message new graphs. The presentation of the animated "waves of data populating the Logarithm plane is excellent!. If made current, it could demonstrate the increasing hope many need.

      1. m mandrewa

        @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.

      2. m mandrewa

        @wojeff Thanks!

    37. Mario Z

      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.

      1. wojeff

        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:

      I would rather know how many are sick and how sick the positives are. As long as you keep testing the number of cases will increase....but if its rare that positives are sick enough to require hospitalizations, that's what is important to me.

    49. Dodger Yassel

      You're an idiot. Your pseudoscience just tries to connect popular topics to some random concept in physics for views. You're a hack.

    50. khoen Da boss

      Is this the guy who had a whole video about using cats to power Norway? Yeah it is.

    51. Jean Poutine

      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.

    52. Davin Riedstra

      This is a great video. Perhaps even the best I've seen in the realm of Covid-19 coverage and understanding. I would love to see the timelapse graph updated for the end of May or beginning of June.

    62. what is life

      Chinas deaths are lies. There must be more deaths than the rate it apparantly is right now. The virus came from there!

      1. karen

        Yes, you are right, a billion people have died here

    63. Rachel’s rants I.

      Can’t believe Chinas data. They lied to us.

    64. AGR

      Imagine believing China’s reported numbers...

    65. 소고기커피

      im s. korean myself but i have to disagree with this. i dont even trust south korean statistics of coronavirus. they actually gave up the test but are using it politically for the sake of their support. all the media are saying koreans are fucking best and never criticize or analyze about the numbers. we are fucked. literally. fucked.

    68. Ciron Soauv

      What is amazing is that, even with under reported numbers, the graph still shows if growth is in exponential phase or not. Government would need to "exponentially" cheat to fake falling out of the curve...

    69. Bigdatamonk Inc.

      @minutephysics Doesn't the graph look similar because the logarithmic scale is too big to measure(comparative minor) deviations? It's like differentiating 2 stars in the sky, despite being very different in size they would look more or less similar, like a dot. Kindly enlighten.

    70. banbanrocks

      Clearly something wrong with Japan figures, no?

      1. Russ Wilkie

        It could just be a culture thing. Japan is a lot more hands off country that actually listens to their government about facemasks and social distancing.

    71. Ron Chasr

      Your not and wont be for a while. Dont be surprised if you have 200,000 or even 1,000,000 dead. America is finally no.1 at something.

    72. Robert Lockwood

      Be nice to see the graphs normalized by cases per 100,000 population but I expect that there would be even more overlap.

      China's number of cases are a lie of course.

      1. banbanrocks

        People like you are the cause of delayed responses in the West. Arrogant and ignorant. Mostly arrogant, I'd say.

    77. savemelofi

      Can someone explain to me why the CCP is being defended in these comments?

      1. savemelofi

        @banbanrocks But the CCP has been covering up the truth.

      2. banbanrocks

        It's about the truth, not CCP.

    78. Ben E

      Probably should throw out chinas numbers...


      Good job Trump, you made the West and the East turn against each other once again.

      1. banbanrocks

        Hope not. If the people of West and East would listen to Trump and really turn against each other, we as mankind deserve to be doomed


      I like how everyone is being biased to China while I sit here as a Chinese and say, “Okay, THIS IS ALL GONNA BE FINE.”

      1. IɴSɪmpʟeTermsJordaɴ

        The problem is China's oppressive, lying, single-party government. The people of China are not to blame for the actions (and non-actions) of the CCP.
