I should have told you more things yesterday, but the events in Brussels made me forget it.
In the beginning of 1982, there was a Canadian couple who was worried about the violence in the world and therefore thinking about moving to a quiet place where they could live in peace and let their children grow up in harmony with nature. So they spun the globe, closed their eyes and pointed at a spot. They liked the result and started to prepare for the big move, which they finally made in September, 1982. Their new home was located in a town called Port Stanley. They were still decorating their house when hell broke loose! In October, their cosy little town became the battle ground between Argentina and Great Britain, in the Falklands / Malvinas war!
But frankly speaking, to live in a small city in Brazil should not pose very big risks for terrorist attacks, more about me and Brazil tomorrow.

And the second one is a revolutionary material which researchers in Arizona want to employ to gather carbon dioxide from the air. Their invention should be able to collect 1 ton of CO2 every day, see reference #3 below.
Today is my blog post # 73, which reminds me of when I was younger and engaged in DX-ing and HAM radio. 73 was the code which meant “Best regards”, commonly used in all contacts between radio amateurs. See reference #4 for origin and more codes.
… That’s what I learned in school & 73 !
