Today, I learned that:

Tomorrow is the Swedish National Day, celebrating the establishment of the modern Swedish state, when the Danes were thrown out. It was instituted on 1523-06-06, when Gustav Vasa was elected King of Sweden.

Legoland

But one day before, today, is the Danish National Day, and of course we must congratulate our Nordic neighbours on their day with the photo above, which was taken at Legoland in Billund on 2003-07-01. And what could be more Danish than Lego, that marvellous innovation made in 1949 by Ole Kirk Christiansen? Is there a better educational toy than Lego, permitting that people of all ages can develop their fantasies? More about Lego in reference #1 below.

One of those Lego lovers is the American artist Nathan Sawaya, who creates his sculptures from millions of Lego bricks. Right now, there is a world-wide tour of his exhibition, and it will come also to Brazil soon. First to São Paulo, start on 2016-08-09, and in November also to Rio de Janeiro. See also reference #2 below.

Today, I learned that:

The 2016 edition of Vasaloppet, that took place earlier today, was the toughest of all the 92 races held so far. Details will follow later on, but let us first discuss what Vasaloppet is and why it is such an important  sports event.

It all started in 1397, when a meeting in the Swedish city of Kalmar, on the East Coast, resulted in a personal union between the kings of Denmark, Sweden and Norway, in which a new king, Erik of Pomerania, was elected to be responsible for both the domestic and foreign policies of the three sovereign states. But the nobility in both Sweden and Denmark did not accept to be put aside and so there were constant conflicts from the 1430s until the end date of the union, which happened in 1523.

The beginning of the end came in 1520, when the Danish king Kristian II (aka Kristian the Good One in Denmark / Kristian the Tyrant in Sweden) invited the Swedish aristocracy to a reconciliation party in Stockholm, but once there, had them all killed in what was later known as the Stockholm Bloodbath. But the nobleman Gustav Ericsson Vasa was able to escape and headed towards Norway. However, a speech he made in Mora, close to the Norwegian border finally convinced the people there to join him in a rebellion against Kristian, although it took so long for them to decide in favor of him that Gustav had already left for Norway on skis. When he arrived in Sälen, a town about 70 km away from Mora, going in a straight line, two good skiers from Mora were able to stop him, explaining that the others in Mora had decided to join Gustav in his battle against Kristian. After  battles in the following years, this rebellion finally led to that the Swedes defeated the Danish. So on June 6, 1523, Gustav Vasa was elected the new king of Sweden. Still today, that date is very important, being celebrated as the Swedish National Day.

In order to celebrate the 400th anniversary of the successful capture of Gustav Vasa by the two Mora skiers, there was instituted a cross-country race, and on March 19, 1922, the first Vasaloppet race was held, but in reverse direction, starting in Sälen and finishing in Mora. 136 skiers participated and the first winner was the 22-year old Ernst Alm, still today the youngest winner of all races held since.

Vasaloppet is the oldest and longest cross-country ski race in the world as well as the one with the highest number of participants, with a current maximum capacity of 15 800 athletes. Originally, the race was 85 km long, but it was prolonged to 90 km some decades ago. In Sweden, it is an almost sacred event, held on the first Sunday of March every year. The athlete with most wins (9 in total) over the years was named Nils Karlsson, with domicile in Mora, thus nick-named Mora-Nisse. The first non-Swede who won the race was the Finn Pekka Kuvaja in 1954. Nowadays, there is a steady fight by the best Swedish and Norwegian skiers, which the latter ones have won during the four most recent races.

Female athletes have been permitted to participate in the race since 1997, and also there is a big fight between Swedish and foreign skiers.

Now over to today’s race. The men’s race resulted in that 26 skiers entered the finish area with a chance to win, with four Norwegian skiers in the top places and the best Swedish skier in 6th place. The women’s race went to Austria and Katerina Smutná, with the leading World Cup skier, Sweden’s Britta Johansson Norgren, in second place.

Problem # 4, Drilling square holes

This problem is very different from the earlier three riddles. The question is: How would you construct a tool to drill square holes? The solution seems impossible, but I have it, and will post it next Saturday, 2016-03-12.

… That’s what I learned in school !
