Warsaw MacDonalds

I needed to make a quick meal stop on my way to the train station, so
popped into a mall and went to the MacDonalds.  This one was easily
the biggest and most sophisticated Macs that I have ever seen.  This
is the computer terminals where you type in your orders (took me a
while to figure out), then to the cash register and a screen where you
could watch your number work its way up the Q.

Diatoms

Here are two diatoms.  I am afraid that I do not offhand know the
names, but very pretty.  Most of what I see are diatoms, of which
there are many hundreds of species.  If anybody is looking for an
interesting scientific topic, I can recommend nothing more pertinent
in these days of concerns for global warming than diatoms.  They occur
in fresh and salt water and are at the base of the food chain, so
essential to everything else.
