Today, I learned that:
Since yesterday was the day of the equinox, when day and night have the same duration all over the world, today on the Southern hemisphere is the first day of Primavera, a word used in e.g. the Portuguese language to denote the season of Spring. It originated in ancient Rome, where it meant the beginning of Summer. Nowadays, it is Spring, but nevertheless I think the word is so graceful!
The photo below shows Rio Tietê, a very important waterway in the State of São Paulo, Brazil. It starts in the east, only 22 km from the South Atlantic ocean, but instead of taking the easiest route, it crosses all of the state to finally merge with Rio Paraná 1 150 km to the West. Se reference #1 below for more interesting information.
In my latest post I invited you to a technical seminar in São Paulo on 2017-09-12. I was fortunate enough to start the seminar with my presentation of “A walk down the memory lane of electronics”. The seminar was a huge success, thanks everyone who showed up! In case you could not make it, do not worry, here is a photo from the presentation:
In reference # 2 below is the complete presentation and reference #3 is how Nordic Light reported the event. Enjoy!
That’s what I learned in school !
