In the 16th century Bohemia minted the first silver 'Thaler', a standardised coin so successful that the name spread, enabling Shakespeare to talk of 'Dollars' long before the USA set up shop. And today the postperson brought some old German coins that still mention Thalers and some with the special badge of the 1930s and 40s.
Today is Bud's birthday so I made him open the present from Jof which was a kick-bottie drone with HD camera, just right for hovering over the nudist beach. When the wind ceases we will try it out. Meanwhile, Grandad flew to Vietnam where the currency is the Dong. He has promised to bring me back some Dong.
Mostly I sat and Minecrafted but as it wasn't actually raining we walked along the seafront for an hour and threw rocks and almost got a tan, should have gone to the nudist beach after all. We passed the time by discussing the crystalline structure of diamond and the melting points of metals. The tide was out and the water was calm, we'll come back tomorrow to see if it's any more interesting.
