1:05 ‘You are likely to spread it to 2-3 other people’ claim is based on the paper: github.com/cmrivers/ncov/blob...

2:51 ‘Number of official cases in the USA is likely to be a huge underestimate’ because of how few test have been administered. See Chart 8 on this page: www.vox.com/future-perfect/20...
3:12 The statement “without drastic measures, the problem gets 10 times worse in a week” is based on the data in the graph below. The data from this graph comes from WHO’s official count. The slope of the lines in this graph determine how quick the so-called ‘doubling time’ is: the time till the problem is 2 times worse. You can see that initially, before much has been done, this slope is often consistent with a doubling time of less than 2 days, but it goes to between 2 and 3 days once a country is at least doing something, but has not imposed a lockdown on nonessential gatherings and closed schools etc. The USA (before the recommendation that just came out) had a doubling time of around 2 days (although it’s hard to say because of the testing situation mentioned below). That translates to the problem being 10 times worse in just under a week. In other places the doubling time was more like 2.5 days, in which case it’s 10 times worse in 8 days. Public awareness and bans on mass gatherings seem to help to bring the doubling time, usually to around 4 days. But when lockdowns are imposed it seems to get dramatically lower.

Introverts like me don't notice a difference.
Lol I’m getting a little too comfortable in my comfort zone tho 😂

@Earthling-39 That's because it really hasn't even begun. That's what I think most people don't realize. You won't need the news a few months from now.
you sound like my daughter, which is a good thing.
It's weird I'm a shut in normally, and the psychological impacts should be nothing, but it's frustrating simply because the choice is taken away.
Hey ... Congratulations on your PhD.
Yay! Thank you!
Also congrats on your degree. I love your content and glad you stepped in to make this video. Hopefully my useless Australian government will get this 'more' right this time.
I’m Australia too (and currently in Aus again for my ‘holiday’ that now might be a little longer than expected). I can not believe how much the government is now dragging its fear... its making me so nervous...
@@LookingGlassUniverse hey are you Indian?
Is it common among physics aspirants that they relate it commonly when it comes to math in day today machenics I kind of notice this analogy in physics aspirants because I am one of those Hahaha . and yes she is absolutely right we must stay home or die .
Never went from subbing to someone from there last video on quantum physics, to unsubbing to someone from a video telling me to stay home and stay scared.
"i made this for my parents. Please share it with anyone who needs it."
*shares this with my parents
I’m finally taking the chance to learn that thing you say is beautiful called...what’s its name? Ah Linear Algebra! :)
Welcome after a lot of time
Your Vectors videos saved my Machine Learning course.
This video may well save my Life :)
Haha, yeah ... came to LGU's DFT video for DSP, ... now subscribed to 3Brown1Brown, PBSSpaceTime, et al. ... also doing ML too. Videos were invaluable for grokking LA
I don't know if you will see this, but I applied a simple mathematical model for coronavirus, and found out that if we do allow things to happen as is now, we will have as many as a quarter of the world population getting infected, so it is really important for these social distancing and drastic measures to take place.
Oh wow... Did you make a video on it? Would you be able to link it?

I love your video on this!! Thank you so much for making it!
@@LookingGlassUniverse Thanks so much.
Always great to see a video from you! The description mentions him twice, but did you see that Grant Sanderson plugged your channel on his TED talk??
I did... that was insanely kind of him!
@@LookingGlassUniverse Good opportunity to utilize added momentum, congratulations regarding new job aside! We all want to see more from you!
@@popwwy Thank you!!
ya i saw
15:53 this part of the ted talk talks about you:)))
I love your content on physics, but this video is a perfect illustration, two years later, of why individuals with specialized knowledge should not be making these decisions. Rule by scientism is deadly and conducive to fascism.
This is an excellent video to share with people. Thank you so much for making it! Stay safe, enjoy your dog, and I hope your family are all OK.
*I won the lottery a few years ago. Now I spend most of my days walking through ravines and surfing the internet. I must say, I am quite content with my peaceful existence. Thanks for listening to my story.*
lucky you :) wish you a happy life
With a name like you, Zeus. You always win :-)
You helped me so much before my qualifying exam this past fall, and I am so grateful for you spreading this message now! Be well, and congratulations on the new job!
Aww! Thank you!
@@LookingGlassUniverse while at home watch spin of indivisible particle
And you can be greatful I'm spreading the virus by hosting a baby shower at Glenhaven showground, send an RSVP if you'd like to join in.
In making this video you placed mathematical modelling above experience, and seemed to forget that there have been many previous pandemics from which lessons could be applied. You also appeared to be unaware that there were existing pandemic preparedness plans, based on prior experience, that included such ideas as minimising economic upheaval and disruption. Ask yourself how you allowed your thinking to be so blinkered.
I'm so happy I came across your channel. I was looking a laymen's explanation of a Fourrier Transform and I landed on your site. I've had a few courses that touched on various topics cover ( i.e Quantum Chemistry, Statistical Thermodynamics, Physical Chemistry, etc). I never truly understood what we covered in class until I came across your videos. Please keep posting and sharing your videos. My friend's eleven year old son is obsessed with learning about Quantum Mechanics, so your videos will also help to encourage his passion for this subject.
Ye, the UK government just advised to stay home, but my company acted early and I am working home since last week.. yesterday I god symptoms.... Thanks to my company prompt reaction I haven't met anybody for a week before getting syntoms, which I guess saved many people !
I'm young and healthy, nothing more then a flu for me
That’s amazing!!! Thank you!
At first Congratulations on your Ph.D! It's an amazing video! So clear and fruitful, also the simulation.
Whatever the book 'Feynman' is looking fantastic and also the 'matter and interaction' :v
Here in Bangladesh we're also spending our Self Quarentine times. Suggest me some books on quantum mechanics! Specially for solid state electronics.
Again thanks for the video Mithuna ❤️
The California Governor gave a Stay Home Order two hours ago. I have literally trained for this my entire life.
I love your other videos, but the fact you made this one is a disappointment to me, if not really a surprise.
I can’t believe I am just discovering your channel. You are an inspiration. Thank you!
🐾 take care. Bye bye from Italy. Cheers 🍷🍷🙏🌀
You did an excellent job at communicating the issues clearly.
2^x growth is much more drastic than x^2 growth people.
2^x is doubling while x^2 is squaring.
Compare 2^(x+1) with (x+1)^2
That is 2^x * 2 vs x^2 + 2x + 1
Subtract the originals and you get
2^x vs 2x + 1
And we all clearly know that exponents get way more out of hand then multiplication because exponents are just ways to express lots of multiplication or division.
Just for a few numbers, 2^1 vs 1^2
The first is bigger
2^2 vs 2^2 they are equal
2^3 vs 3^2 8 vs 9
2^4 vs 4^2 16 vs 16
2^5 vs 5^2 32 vs 25
2^6 vs 6^2 64 vs 36
Can you make a video on what road you decided to take with your physics degree, I’m currently in college for physics heavily interested In QM but unsure on what jobs to apply for when I’m done.
You make so much sense with what your saying which helps me to understand the rate of spread. Thanks a whole lot. The Brains.
I've taken a long hiatus from learning about quantum mechanics, but I still keep you on my subscriptions and I'm so glad to see you're still doing the videos! It's been absolutely crazy here in the states during the pandemic. Keep up the production! I'll be sharing this video. (:
(My apologies if you're in the states - an assumption in hindsight)
Oops. This video didn't age well. Scientism at its worst. Lol
6 months later I wish so many more people took heed of the seriousness of the world situation. Here in the US, cases are above 6.7million as of Sep 21.
I see so many ppl just not caring, thinking, "oh it won't happen to me". social distancing isn't practiced as well as it should.
thank you for sharing your thoughts and hope more % of ppl adjust their routines and schedule, while taking precautions so we can put an end to the Covid spread
This is great content. I love your channel. Stay healthy, Mithuna. Stay healthy, everyone. We have to use science and human solidarity to minimize the devastating effects of this disease. It CAN be done. We can do it but it requires knowledge and self-control. On a side note, this is still a disease that has a comparatively low death rate compared to some truly horrible diseases out there. It's clear to me that the world's systems aren't set up to deal with this type of catastrophe. Can you imagine what it would be like if, say, bird flu had become more easily spread to humans the way coronavirus has become? That has a death rate of around 60%! The world needs ever more investment in research and appreciation of science and the wonderful work many scientists are doing. Stay safe, everyone.
I am not able to understand potential difference and potential.
what the hell is electric potential
I never understood. will you help?
to let me and anyone else like me understand.
Hello ma'am!!! I'm new to your channel and one of your videos in which you explained that how you became a PHD student of quantum mechanics really inspired me..... I got distracted from my aim ( i.e. to be a physicist) but your video really helped. Thank you for inspiring me.
BTW, Are you Indian?
You make this all so easy to follow. A great explanation about why we should practice social distancing and “flatten the curve”. Thank you.
and even with China's ZERO Covid policy , how did that work out?
A friend who is a department head in a hospital not too far away from me told me about what it was like to work in a covid peak early on. At the time he was exhausted and desperate, wondering whether he would survive himself. That curve is no joking matter. As for China, their containment, though inhuman, did largely contain the spread: practically no curve at all. The result is a population that is largely not innoculated (very poor roll-out of vaccine and fewer actual covid survivors than elsewhere) proportionately. Now their lock-down has been completely reversed and their curve is skyrocketing. Sadly predictable.
@@knerduno5942 no attempt to flatten the curve there. After their hyper strict lockdown and minimalist vaccination campaign with a middle of the range vaccine, they just dropped their guard. Sad. And a bit strange behaviour on the part of authorities.
@@tonybalinski2398 Locking down entire cities is not trying to "flatten the curve"??
@@knerduno5942 no: going from complete lockdown to complete relaxation with only a half-baked vaccination program completed was the mistake. Essentially exposing the virus to a large immunologically naïve population means it was like the early days of the pandemic all over again.
mam i wanna know about what is angular momentum ? in our book it said that the cross product of radius vector and linear momentum is called angular momentum but mam i can not understand it please clear this concept please
Hi i can´t understand what it´s magnetice field, i know that the electron produce the magnetic field but what is it ? i think the magnetic field can be a wave, but i don´t know, can you do a video about it.
You can watch science asylum's video on relativity
@@Ghost-vg6iq thank you very much .
Looking Glass Universe: your one-stop channel for mind-blowing quantum physics, sensible public health advise in a country with crumbling social infrastructure, and a reassuring ray of sunshine in 2020's rapidly impending Mad Max cannibal dystopia.
First time I really understood the double slits experiment was through one of your videos. Obviously it blew my mind and I remember in the next few days I kept coming back to your channel trying to understand more about the topic. Haha good times I'm glad to see you are doing well
Thank you for your videos! I've really enjoyed them for the past few years, and I hope you'll continue making more of them. Are you familiar with this researcher called Shohini Ghose? I just hear her speaking at a colloquium, and thought that her research group might be really close to your interests!
Edit: Oh and congratulations on your PhD! So cool!
I miss having new videos form this channel. I started watching even before there was a face put to the camera. Back when every thing was drawn.
why is she gone?
5 months later the virus is still here. I guess we have to learn to live with it. :(
Greetings from 1 year in the future. It's still bad.
@@shawniscoolerthanyou things are a little better. Got my vaccine and getting more hours at work. But yeah it still sucks.
Thank you for addressing my rebellious and doubtful young adult self.... missed your quality videos ! Randomly brought you up to my math professor :)
Squish the curve and break the chain! We definitely have to stop the virus from reaching our vulnerable contacts and family.
Plz make more videos and eventually make us explain every bit of quantum world
"Two weeks to flatten the curve". Freedom or safety? You only get to choose one.
Single nucleotide polymorphisms. Discuss.
Game theory-wise we just need to reach Nash equilibrium, where everyone "plays" the optimal strategy: to stay home. Your analysis is just what people and governments need to understand to minimize the transmission. A sincere thank-you for posting this video!
I’ve always found your videos tremendously helpful. Your illustrations are are wonderful, and explanations so clear. This is one of your most helpful videos by far and, like all of your other videos, has made a difficult subject easier to understand.
That is very kind of you! Thank you!
Thanks for the upload. Its informative and (hopefully) helpful. I'll share it with my coworkers.
I just discovered your channel, you're brilliant, your videos are brilliant and I'm very happy for you. I am American, I was born with medical issues and I've spent most of my life working for health benefits and spending all my money on health related crap. Thus, I never had the opportunity to really study Physics at the university and I'm eternally sad about it. So, I was watching your video on learning on your own and I plan to get all of those books. In the meantime, my family and I are stuck at home (isolated 8 months straight now), no friends, no visits, no nothing.. while all our neighbors are not practicing even mask wearing, our president has infected the entire white house and is encouraging people to race and and face the virus with strength (as opposed to intelligence). So there you are. I wish we could immigrate and that I could go to school and teach physics but maybe in the next lifetime. :(
Social distancing is something i been doing my whole life, sure probably not healthy but i'm ok with it. Usually only social interaction i have is with my co-workers. Now that i can't actually go to public places willy nilly it actually feels like i'm isolated, but the silly thing is that is just normal for me, but it's the fact that we shouldn't that makes it hard, it's like the rebel in me wants to get out. I can only imagine those who are used to social gatherings on top of now needing to stay home must be really difficult to deal with, hard to resist scratching that itch. If am having this anxiety, I can only imagine social people must feel much worse. But if we can at least cut out as much as possible by avoiding unnecessary social gatherings, i do think it's worth the lives saved in the long run. just gotta power through it! And if you do have to go out, try to keep your distance from others, wash hands regularly, and do not touch your face.
Thank you very much for this video. I straightly subscribed your channel. And I watched some of your other videos. You're brilliant. I'm teaching maths in english to my students (France). And I make them work on this video. So thanks again. I do love the simulation at 6:00. To make it even more realistic, you could make some brown dots disappear ( to take in count the people who die). Sorry, it's a little bit morbid, but once again, it's just to make your simulation even more realistic. I'm looking forward to watching your next video.
Absolutely right! In the description I linked an other simulation that has more parameters- it would make a great maths lesson. Thank you for being such a diligent teacher under such trying circumstances! Good luck!!
thanks for the PSA and super-glad you're okay and still with us, creatively
One person staying home could literally save many lives.
The simulation at 6:00 is beautiful.
Very good video with great meaningful content about this unprecedented event!! You’re helping to save countless lives, in more ways than you’ll ever know or maybe you do know😁. I will most definitely share this video!
Thanks for making this video. There is a real danger for the hospital system to collapse. Please work together and slow down the infection rate so human kind can get through this as soon as possible.
Yeah...NOT
I feel angry. I feel like my life is being stripped away from me and all the things I’ve ever known or loved are being destroyed. I never have the opportunity to do anything besides the things I can do in my house and it’s really making me wish things could go back to normal.
Lovely! Watchers make sure to explain this to elderly people you know. In my country, of all demographic categories it's the elderly that seem the least careful. They just roam the streets while most others are staying at home. The oldest generations are used to much more immediate and much deadlier threats, so they easily underestimate such more subtle and insidious one.
This seems sadly quite true...
It is only through developing a culture of safety, adopted by everybody, that we can ensure that everyone stays safe. You cannot develop this culture by only thinking about your own risk because your own risk is so small.
Just wanted to say ,u are amazing ,I really admire how u explain things .,it's really amazing
What an adorable dog! Just discovered your channel and I look forward to some well-spent hours of my quarantine time :)
Thank you, she’s the best! I’ll have time to make a lot more videos soon
Did anyone knows which is the best channel to study integration
Great video, sums up all the points really well. The simulation is very cool too, didn't see it before.
Also congrats on being shouted out at TED!
Thanks so much- that was so kind of Grant!
good stuff, hope the PhD study is still going well during all this. start mine in feb for 3D Graphics and visualisation (vr focus)
I love 3D Graphics! I don't know how you expect to be working on any projects during an economic great depression, but good luck! Too bad suicide rates and drug overdoses doubling this year doesn't matter when we flatten the curve.... right?
hey, are you alright?.. why no new videos? i hope you are.. your channel was one of the best discoveries for me. finally someone was talking about the actual reality behind all these models..
I'm sure it's nice to stay home for two weeks when you are financially secure but one two weeks or more of income disappears and you end up homeless and broke you should find alternative ways to accumulate money from those people who have more than enough
Yes, this is a huge problem
@@LookingGlassUniverse 10 months later you still think it's a good idea to abide by covid19 rules? I live in a city in Mexico where no lockdown has occurred and this compounding virulence you mention has not took effect or if it has noone has noticed.
Also, if the medical industry actually understood that our biology is controlled by the information quanta in photons from the Sun that we wouldn't get sick with chronic modern diseases.
That dog definitely knows the meaning of "walk."
Great Public Service Announcement! We were wondering when another video would come out. Keep up the great work. These videos are amazing!
A lot more videos soon now that I’ve finished my phd and I’m under house arrest 😛 thanks so much for the lovely comment!
Vulnerable people, and people in contact with them, must be super careful (stay home!). Everybody else, OUT and live!
Thank you so much for doing this.

Congrats!!
Please do a video on Wigner’s friend someday so far I cannot understand others, just won’t sink in.
Can you describe hidden variable
Greetings from italy 😘
Best explanation so far. Why aren't you the PM of Australia?
Happy to see you back 😊. Please make more videos!
yes please stay home, if you love yourself and your fellow human being brothers. love from italy
We shouldn’t be staying home. Research herd immunity, if 40% of the population gets it, that can help slow the spread
wow! just wow! Such great content in these videos. I arrived here after searching for recommended QM textbooks for the library, now I'm telling everybody to wash their hands while I earn linear algebra. 😍 You've certainly made a difference today 😄
Awww!! This comment is way too sweet- thank you!!
Thanks for the great video.
Already a handful of pretty insane comment, so that show you do a useful work.
This is an amazing explanation. I'm completely bought.
Thank you so much for this video !!
I have a doubt, if I get the symptoms of the infection , what should I do ? Go to the hospital to get treated or stay at home in the fear of spreading my infection to others?? I'm sorry if I'm being silly but our own lives are always the priority #human_mentality
Hey, this is an important question! The answer depends a lot on the country you are in. Some countries are not testing as widely as others. If you check your government’s website they will give advice. Alternatively, call your doctor’s office and ask them. They can tell you the protocol. Good luck!!
Following the recommendations of the US government, if you get the symptoms of incfection, you should not leave your home unless the symptoms are serious.
www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/steps-when-sick.html
If it turns out that you are indeed infected, you would unnecessarily put the lives of many people at risk. More importantly, hospitals can only treat so many people at once. It is recommended that you call a general practitioner or a pharmacist to avoid overwhelming health care facilities. That is probably the main risk currently.
I would also tend to instinctively prioritise my own health however, as mentioned in the video, most people can recover at home.
I hope this helps, take care of yourself.
Thanks for all of you who have replied here, I'm living in India and yes the government has declared the helplines.. I have not developed any kind of symptoms and the city I live in is not yet highly affected .. this was just a doubt I had pertaining to the spread of the disease....
Thank u again for replying

Thanks for breaking it down!
Haha, I am an introvert. Staying at home is my passion.
I still haven't thanked you properly (comment that is) for your last video (How to learn Quantum Mechanics on your own). It's made a HUGE impact on my grades! (not Quantum Mechanics of course). So thank you and stay safe!
Aww! Thank you!
Really amazing to see the simulation
Amazing.....
A great way to reduce the number of cases is for the federal government to give money for food and utilities and other necessities including medication if not we're not in for a pretty picture
Really good and informative video!
Thank you for this video. It is great.
Such a great video.
How many life saving shoots you took?
Sorry for being off topic, but can you make a video on "how can one self study physics?" there aren't any good videos that explains what topics to learn or how to study? It would be great if you could upload something like it

@@LookingGlassUniverse uhh anything.. your favourite reads? (First on the list are Alice in wonderland and Through the looking glass? xD)
Very informative and great animations. 👌👌 Surprised we haven't found your channel sooner
Hi ! Thank you very much for that video. I live in France and you can imagine how hard it is to live alone for 4/5 weeks, in a small appartment. That's why I keep in touch with my friends online, with my colleagues, and spend time on things I never have time to. It is hard to live in loneliness but it is necessary for the society
Same here in Belgium we just started a lockdown
Thank you to you and everyone in (the locked down parts of) Europe for doing this. I can only imagine how tough this is...
Please make a video on energy time uncertainty.
A snippet of this video was played on the latest episode of the podcast Rabbit Hole 👏 they were discussing UA-cam combating misinformation about COVID-19.
Schools haven't shut down in Australia and I have to attend school due to being in high school. How do you stay at home when the system does not want u to?
Yeah, I’m in Aus at the moment and the government’s stance has been very disappointing. Thank you so much for caring, but of course you’ll have to go to school until they shut it down.
Im not staying home for the rest of my life so an 80 year old can live a few years.
lol its a hype anyway....watch #filmyourhospital and share;)
hope you are doing well.
Hello, a dumb question and perhaps personal but as a quantum physicist do you identify as an atheist?
