Today, I learned that:

The world today is upside down, even in the so called Developed world, between old traditions, which seem to hinder more than help, and interesting innovations using old concepts in a totally new way.

The latter can be clearly seen in this lecture held at the branch offices of Chalmers University of Technology at Lindholmen in Gothenburg, Sweden, see photo above. Since I was visiting Gothenburg that day, I first visited my friend Lars Lindsköld, who made that interesting lecture about personal identification numbers in March, see my post of

. Here is a selfie we took to immortalize our encounter:

Then I listened attentively to a lecture by Lars Larsson, professor in Mechanics and Marine Science at Chalmers, where he described a concept boat. Starting with a small dinghy which top speed was 5 knots, by placing wings on centre board and rudder, and using carbon fibre and graphene, he and his team were able to transform that slow boat into a racer boat reaching 20 knots! See references #1 and #2 below, showing the main highlights of the lecture and a video of the foiling optimist. Thanks Lars for letting me share your knowledge with the world! Also, here is a photo of the professor and his racer dinghy:

Returning to the initial paragraph of this post, the old traditions which hinder the contemporary life are of course the British habit of the Queen announcing the new government by reading from a document, which was manually written with ink on “goatskin” that takes three days to dry! See reference # 3 below.

Trevlig midsommar!

… That’s what I learned in school !
