Today,  March 14 is Pi Day,  that mathematical constant 3.14...  Thus, the third month of the year, March 14.  Sometimes this day is honored on July 22 because 22 divided by 7 is a very close approximation of pi.  UNESCO in 2019 designated Pi Day as the International Day of Mathematics. Celebrations often involve eating pie or some kind of pi recitation.  Founded in 1988 by Larry Shaw of the San Francisco Exploratorium.  Although there is no practical reason to calculate pi to so many digits, a Swiss team found the first 62.83 trillion of them. Two bits of politics before I get into the Norovirus.   Delay...delay...delay .  When one wants to delay a court trial, it's because you're guilty.  That's certainly the case with Donald Trump, and looks like his strategy is working.  Pushing these trials until next year is key to his avoiding jail, for if he beats Biden, Trump can pardon himself or kill the process if he becomes president.   The Florida documents case will be pushed

   We have suffered  five COVID-19 waves .  Will there be a 6th? Initially, cases were dominated by large cities, which are mostly Democratic.  Thus, the first wave experience a lot fewer Republican deaths.  Later waves gravitated towards fewer Democratic deaths. A higher percentage of Biden-voters get vaccinated.   Over 91% of Democrats have had at least one shot, and only 60% of Republicans . The primary reason is  vaccination , as per million population, 250 deaths occurred in Trump counties, compared to 78 in Biden counties. About that possible 6th wave?  Most likely, when the Omicron Stealth B2 subvariant creates a mild bump in April.  Then, WHO can pretty much declare the end of this pandemic.  But I've now said this at least three times. Incidentally, just about 25% of Americans have been infected with COVID-19.  World?  Only 6%.   Of course, this is where asymptomaticity and under reporting come into play.  If it turns out that the asymptomatic rate is 50%, then 50% of Amer
