One of the most brilliantly narrated and intense short documentary. Did'nt take a second of my attention span away. Kudos to the HarvardX team.

Locals: you know nothing John Snow Johnny boi: hold my ghost map

This isn’t the John Snow I was looking for (no I wasn’t looking for Jon Snow) but I’m glad I came across this video by accident. It is very interesting. Ok, now I resume my search for the other John Snow.

Hey you do know that it isn't technically Vlad the Impala right? pale. Its Vlad the Impaler, technically. Have a good one.

I grew up in London and learned more from this video than anything we did at school when I was a kid! Excellent video and very interesting. Thank you to all involved!

Today we are in another pandemic, COVID-19. Year 2020. When I was just 11 some six years ago, I contracted a mild case of cholera in a wealthy First World area, namely Pacific Palisades, California. My case lasted for about 5 days. I had the frequent -rice water- stools and had been puking as well (more out the backside). My paediatrician was called and I had been diagnosied with cholera and given some samples he had of WHO ORS (Oral rehydration salts) I made my recover without complication. So yes, as an adolescent, I am a survivor of cholera like in the 21 century.

[@wannacashmeoutside]

There was a case of cholera at UCSF just 3 months ago (my mom works in peds) . She did just come back from Cambodia though.

I read a book about cholera and came across a very informative video while doing some research. The video provided a realistic comparison between London then and now, which was helpful. It was interesting to learn that some places that were once affected by the cholera outbreak are now pubs. Now, in 2023, while experiencing COVID-19, I deeply understand why we need to protect the environment and am doing what I can. It's interesting to note that the cholera outbreak in London was also caused b

Very interesting video and well presented, thank you. I walk through that part of Soho most weekends when I meet with friends, I walk from Old Compton Street to catch my bus home from Oxford Circus.

[@mbuonaguro102]

Great video

[@renukapulchand3772]

This video was very informational

[@stischer47]

I had the pleasure and excitement of going to the site of the pump named by John Snow. The whole idea of pattern matching was my area of AI. To realize that John Snow understood the patterns was stunning.

[@kiokomutua3209]

great piece here

[@CaptainCalculus]

Since you made this video they have taken the granite slab away and have replaced it with a replica of the original pump and concrete stand.

[@des_smith7658]

Like at the general election

[@tonayflattum-riemers7982]

Great video. What always bothered me is that snows south London study which proved the connection with water and cholera not the broad street investigation. In fact there are a lot of weird details with the pump.. The deaths declined prior to the handle removal on the 8th. The only physician who saw the suspected index patient didn’t believe it was cholera. Or the general board of healths house to house inquiry team finding evidence that would explain shows strange finding which can be found in the appendix of the report of scientific inquiry. Such as the hampstead widow had another connection to the area. Her son lived with her but continued to travel to the broad street area every day, meeting with one of his infected coworkers.

how long did it take for the government to finally believe john snow? like specifically?

[@SStupendous]

although they seemingly listened to him in this epidemic, it wasn't until the mid 1860's that they fully accepted him.

brilliant observation In the midst of chaos, you can think beyond your time! Implementing a study that moved society, it helped the community affected by the cholera epidemic.

In using AI and BIG Data now this kind of thing, I doubt if it will be found.. because these exception data points which really were the clue to finding the root cause, would be cleaned up as outliners... So exceptions have to be carefully studied, thoroughly analyzed before blindly removing them just because it does not fit your theory.. else you will thoroughly miss the forest for trees.
