In spite of evidence to the contrary, many people persist in the false belief that masks do not work, or that respiratory viruses are somehow not airborne. The Physics of aerosols is conceptually simple though mathematically complex. It’s also within the realm of what an undergraduate student in Physics, Chemistry, or Engineering would encounter alongContinue reading “COVID Aerosol Physics”

Stupid Human Tricks
The pandemic is going to extend well into 2022 for at least one reason … for every one of the 331 million citizens of the United States, there are 2.6 citizens of India who HAVE NOT been exposed to SARS-CoV-2 or been vaccinated. That’s roughly 880 million susceptible hosts in just one country on theContinue reading “Stupid Human Tricks”
COVID Vaccine Ingredients
The Pfizer vaccine has the following ingredients, which are essentially the same as what’s in the Moderna version, but they use a few different salts in their pH control and the lipid formula is slightly different. The explanations under the headings that follow include the percentage that each major ingredient group comprises. mRNA lipids ((4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate),Continue reading “COVID Vaccine Ingredients”
On Understanding Science and Loving Your Neighbor
Science is an enterprise armed with methodological tools that describe and explain how Nature unfolds. In the Natural Sciences, we have the luxury of physical laws that lend us predictive power because of the empirically familiar regularities present in Nature. Sometimes the math is simple and sometimes it is not. Now please forgive me asContinue reading “On Understanding Science and Loving Your Neighbor”
Beating COVID With Better Ventilation
In less than 19 minutes, this presentation seeks to answer the question … How can Indoor Air Quality (IAQ) address the problem of SARS CoV-2? Easy. Physics describes and Engineering solves the problems that IAQ experts have known for decades. IAQ transcends this pandemic and can deliver major gains for Public Health if we willContinue reading “Beating COVID With Better Ventilation”
Poor Ventilation in Schools
This is just a quick listing of research on how poorly ventilated most school buildings are. Ventilation is more important than ever in the COVID era, but we should have done better long ago for the sake of student health and learning. Here are some details. NOTE: some articles will address other venues, such asContinue reading “Poor Ventilation in Schools”
Blown Away
I want to offer some advice to all of my friends who are school teachers, as well as anyone who wants to make sure that a classroom is safe for both kids and teachers as we open school again in 2020. It is unlikely that government or districts will have the money to make allContinue reading “Blown Away”
COVID Links
The purpose of this post is to simply list useful links related to understanding the dynamics of COVID-19. THIS LINK takes you to my musings on these things and more. Scroll to the bottom for an excellent set of videos that say it all. Great Explanations by various experts who not only possess the requisiteContinue reading “COVID Links”
How To Reduce COVID Risk With Worship Teams
Singing and wind instruments are the most productive aerosol generating activities in church life and aerosols are the main method of transmitting an airborne virus. Large aerosol droplets at close range and small (long hang time) aerosol droplets in the air at long range. How much exposure to COVID-19 is the issue [1] and theContinue reading “How To Reduce COVID Risk With Worship Teams”
The Maze Runner Mask: Aerosol Death Cure
The purpose of this post is to take down the persistent misinformation that continues to spread about the efficacy of masks in preventing the spread of COVID-19, or for that matter, any respiratory virus. In other posts I provide scientific research-based support and explanations of how and why masks work in terms of how theyContinue reading “The Maze Runner Mask: Aerosol Death Cure”
