On June 22, Dr. Ellie Murray of Boston University posted a response, calling @DrEricDing's tweet "bad and misleading".
A number of other Infectious Disease Epidemiologists (ID Epis) joined Dr. Murray to criticize @DrEricDing, mostly with disrespectful tweets.
@DrEricDing was the first epidemiologist who correctly broke the news about the #coronavirus pandemic on 2020 Jan 20. He received a similar backlash from some ID Epis for making minor inaccurate statements, and was called an "alarmist" & a "fear-monger".
An example of anti-mask rhetoric can be seen in the video below by a Mr. Huff. I will explain why everything that he says here is scientifically incorrect and a danger to public health. (I do not know Mr. Huff or his motivations.)
In this thread, I will explain why this equation is not only wrong, but is also completely unnecessary — especially when we have clear alternative measures that can guide #COVID policies and decisions.
* Fast forward to tweet # 11 if you already know Dimensional Analysis.
One of the first subjects in physics is "Dimensional Analysis". It needs to be emphasized more in high school and college physics courses.
See this @wikipedia article for a technical description:
In this PEDAGOGICAL thread, I will explain how I came up with this number. This thread is not meant for systems experts.
I became interested in, and very concerned about, the spread of #coronavirus since January 2020, when I saw the initial datasets from #Wuhan.
I am an applied mathematician, and I specialize in modeling dynamic systems, besides other things. I am not an epidemiologist, but the spread of infectious diseases are governed by the same mathematical rules that govern dynamical systems in general.
@PoliticoRyan Dear @PoliticoRyan: Thank you for your nice analysis. I completely agree w India & homeless/refugee shelters (#1 & #3). But not so sure about #Russia, #Germany, & #Iceland. Rate of spread depends on PREVENTION/MITIGATION POLICIES in a community/country.
@PoliticoRyan#Russia seems to have established very strict intervention measures, including mandatory quarantines and lockdowns. They are probably not truthful about their testing stats, but that has not much to do with the dynamics of disease spread.
@PoliticoRyan For example, #China most probably underreported cases/deaths by at least 10×, but they succeeded in controlling the spread through strict nationwide prevention/mitigation measures.
@ErickFernandez I am not a political person. But this eye-opening video compilation points to a much deeper problem in our society.
The education system in our country has failed to teach science to students, and our media/tv/movies constantly degrade scientists.
@ErickFernandez So, people listen to pundits and celebrities instead of scientists and experts. These experts have scientifically studied a problem for years, therefore understand it better and can design methods of prevention and mitigation.
@ErickFernandez This same problem also applies to career politicians who have no understanding of how complex systems work, yet they make policies and decisions for a country, a highly complex system with many types of underlying interactions and feedbacks.
