Today, I learned that:

Exactly 49 years ago, 1967-09-03, Sweden changed the rules for driving, from the left-hand side of the road to the right-hand side. It had already been the subject of a referendum held in 1955, where 82,9 % of all votes were in favour of status quo, i.e. continue to drive of the left-hand side. But the referendum was not decisive, only consultative, and external pressure of unifying the “right side” for driving eventually had the Swedish parliament decide on a change.

Already one year before the switch would take place, the actions started to teach the population how they should behave while driving after “H-dagen” (‘H Day’, where H stands for “höger”, the Swedish word for ‘right’). And thus the switch itself went very smoothly, no major accidents. Even though I was too young to have a driver’s license myself, I still remember waking up in the morning and seeing how the cars started to move from the left side of the road to the right one at 05:00 in the morning, and then at 06:00 was finally given the “go” signal. Below are some interesting images from the switch, complete articles can be found in references # 1 and 2 below.

Dagen H

Six illustrations related to the Swedish left-to-right switch. In the upper row, from left to right: – Propaganda on a Stockholm bus appealing to vote NO in the referendum in 1955; – The people managing the switch showing the sign with a big H, which was placed in thousands of places in Swedish roads; – Kungsgatan in Stockholm during the switch. In the lower row, from left to right: – The official symbol of the switch; – Gloves to remind the driver to drive on the RIGHT side; – This road sign ceased to exist at the switch, it meant that the earlier limited velocity now was invalid, thus imposing no formal limits to the velocity, but after the switch there was no more free velocity on Swedish highways .

And so you may ask, what does the following photo have in common with traffic? Well, it was taken in an EU country that still insists on driving on the left side of the road. No, it is not Britain, but one of its former colonies, Malta, located in the Mediterranean sea. My friend Rikke just returned from a marvellous vacation there, and besides this beautiful photo, she has promised us to deliver more like that one. We very much look forward to it, in the meantime here are our warmest thanks to her!

Today, I learned that:

We have arrived at the Easter weekend and in most countries where Easter is celebrated, it is normally Easter Sunday which attracts the main interest culinarywise. Sweden is an exception, there it is Easter Eve, Saturday, that has that attribute.

So I would like to contribute with a marvellous dessert to break the normal sweets tradition. Avocado for most people is known for its use in appetizers, e.g. filling it with prawns, caviar, etc., and of course as a guacamole dip for the tortillas or nachos. But in Brazil, we like to eat the avocado sweet, mixing its pulp with sugar and water / milk, to form a delicious cream. See the photo and reference #1 below.

Creme de abacate

Avocado cream is extremely simple to make, and yet it is so tasty. Just divide the fruit in two halves, scrape out the pulp and place it in a blender. Add some sugar and a liquid, either water or milk. Dose and blend well to desired consistency. If you use water, then some lime will give the cream a delightful contrast. But do not add lime if you are using milk, they do not go well together chemically.

This morning, I heard some distressing news from the local news program of SR Sjuhärad. It was reported that the new EU regulations about traffic safety does not oblige the car driver to have his/her tail lights lit when out driving in the fog. To me, and so many others, that seems like a dangerous degradation of the safety rules. Let us hope that the human drivers have more wit than the EU legislators and leave the lights on. See also reference #2 below.

In two earliers posts, 2016-03-10 and 2016-03-12, I reported about the outcome of the first three games of Go in a best of five series challenge between the AlphaGo computer and the Korean master Lee Sedol. Here comes the final report, in which Lee won his first game and AlphaGo won one more. So the challenge victory went to AlphaGo with a 4-1 match record.


The results of games 4 and 5 in the challenge series between AlphaGo and Lee Sedol show how the two opponents won one game each. The final result of the 5-game series is thus 4-1 to AlphaGo
