Scientific Illiteracy at the CDC and White House

Nancy Pelosi kissed the Pretender in Chief Biden on his cheek before she was known to have Covid-19.  But no worry.  The White House says she was not within 6 feet of him for 15 minutes, so according to the CDC criteria for close contact for Covid-19, she was under the time limit.  No worry.

Most people have enough sense to understand the how close they were matters.  They were not 6 feet apart, they were an inch apart.  Common sense proves here to be vastly superior to the “science” of the CDC and the regulatory sense of the White House.

Let us see if we can explain this to the scientifically illiterate of the CDC and the White House.  A simple model of the dispersion of the virus as it spreads out over distance is that it is diluted as the cubic power of the distance between the people involved.  The density of the virus in the air is approximately proportional to the volume of a sphere centered on the point of emission.  Now the distance between Nancy and Joe was about 1 inch and its cube is 1 cubic inch.  6 feet in inches is 72 inches, whose cube is 373,248 cubic inches.  So the dose rate of virus someone 6 feet away from Nancy is about 1/373,248 times that which Joe experienced.  This number is 2.68 millionths.

The threshold viral dose for close contact is this viral density times the time of exposure.  The CDC critical time is 15 minutes, so the critical time when the dose rate is 373,248 times greater than it is at 6 feet is 15 minutes/373,248 = 0.000040 minutes or 0.0024 seconds.

Nancy must be the fastest kisser ever if she managed to smack the Great Pretender in less than 0.0024 seconds.  Not to mention that she had to have spent some additional time within that 6 foot distance.

Science and good old American common sense agree that the CDC and the White House are wacko!

You know, if Nancy can move so fast that her bussing the Great Pretender on the cheek was really no cause of Covid-19 concern, then her propulsion system is so good, we should send her on the first human mission to Alpha Centauri.  She can traverse that 4 light years distance in no time at all.  Nancy, it is your patriotic duty to take on this mission to Alpha Centauri!  Do it right now.

As for the CDC, that distance within 6 feet matters hugely and cannot be ignored in any scientific criterion for close contact.
