COVID Aerosol Physics

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”

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”

Self-driving Cars and Stuff

Background Human beings with two functioning eyeballs have what researchers call stereoscopic (or binocular) vision. In other words, you see with both eyes. However, the brain delivers a cyclopean (one-eyed) perception of that binocular reality. The visual cortex then processes the images formed in the eye that subsequently activate the retina and so forth andContinue reading “Self-driving Cars and Stuff”

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”

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”

Shining the Light of Truth … on Your Blood?

What if I told you … that shining a laser on a blood sample could tell you whether or not your symptoms were due to a virus or a bacteria? What if this handheld biosensor could detect virus antibodies too? The simple fact that there is no need to send the test off and waitContinue reading “Shining the Light of Truth … on Your Blood?”
