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

SARS-CoV-2 is the name of the pandemic virus first identified in Wuhan, China in December 2019.  Why that name?  Because it looked genetically similar to the virus that caused the 2003 SARS outbreak.  You've regularly seen the COVID-19 virus as a sphere with what looks like golf tees sticking out of the surface.  First, this virus is so small that you can't see it using an ordinary microscope. Bacteria are between 0.2 and 2 micrometers, so you can't even see this in a compound light microscope. Viruses are not measured in micrometers, but nanometers, which is one-thousandth a micrometer.  The coronavirus is just 50 nanometers across, or 0.05 micrometers. But visible light ranges from 300 to 700 nanometer, so light photons are too large to distinguish something so small as 50 nm. You thus turn to an electron microscope, invented in 1930, but improved to what is now called a Scanning Electron Microscope, or SEM.   Yes, instead of photons, something so small as an electron mus

On this nostalgic Tuesday, I look back at my posting of 2012:   Kung Hee Fat Choy , which means Happy New Year.  I said: This is the year of the dragon, which is the most favorable, luckiest and revered zodiac sign.  Dragons are confident, generous, colorful, gifted and operate on a grand scale.  Hmm...no wonder I am a dragon.  Both  weddings and births will spike this year in the Orient .  We dragons, though, can be conceited, tactless, and solitary.   The more I look at the above, the more it makes sense, for I can be conceited, tactless and solitary.  I also said: There are, actually,  ten different dragons .  Twelve years ago it was metal and in 2024 it will be wood.  This year?  The  water dragon , something that won't happen again for 120 years.  The founders of  Blue Revolution Hawaii  have accepted the Blue Marine Dragon as our mascot . I showed a photo of the fireworks at the Marina Bay Sands in Singapore: How old is China?  This posting mentioned above said:   In the West

In May of 2021:  The CDC said fully vaccinated individuals can, in most cases,   drop protective face wear   and no longer need to stay six feet apart. Unvaccinated people still need to follow stricter guidelines, as they remain at risk . Then a few months ago,  mask mandates began returning .  The new subvariants seemed to infect those who already had suffered from this virus, or even if you were vaccinated, so the vulnerable, like 80-year old Joe Biden, were advised to wear masks. There are those who don't fear much getting respiratory infections, and there are those who do.  The latter wear a face mask just about anywhere.  The former, just the opposite.   As of September of this year , only 12% of Americans said they wore a mask outside their home always or most of the time over the past seven days.  That's down from 27% in January of this year and 60% in January 2022. So this posting is for those who don't know whether to wear a mask or not.   It is clear to most of us
