How much coronavirus is needed to infect everyone on Earth? (Patreon)

Probably the most important thing you can do during this pandemic is not touch things you dont have to!

Sadly not even I have a microscope powerful enough to see a virus.  Indeed no optical microscope can see a virus- you would need to go to one of the multitude of electron microscopes.   Not only are those crazy expensive and difficult to run, I would also need a virus!!!

Human viruses are almost the only thing I will have nothing to do with.  Im happy to deal with things that explode, things that are radioactive, and things that are mind blowingly toxic.  Viruses-NO!!

I can easily protect myself against things that explode.  I can easily detect even small amounts of radiation, and can at least see things that are poisonous.  A single virus particle can in principal infect you.  You have no easy way of detecting it, or even knowing if you're effectively protecting yourself against it.  You just do what you think is best with almost no measure of how accurate what your doing is!  In these circumstances, probably the best way of not getting the virus on you, is to not touch anything!   A point that can be easily demonstrated simply by dipping your finger into a fine powdered graphite!
