Today, I learned that:

Continuing the post from 2018-09-29, here are two more interesting British facts from the world of Sports:

Wimbledon surrenders to John Isner

The American tennis player John Isner is, among other things, well known for having participated in the two longest fifth sets in the history of the Wimbledon tournament. In 2010, he beat the Frenchman Nicholas Mahut after winning the fifth set by 70-68, after three calendar days and 8 h 11 min of playing time. Then in this year’s tournament, in the semifinals, he lost to the South African player Kevin Anderson by 26-24 in the fifth set.

But that is the end of such marathon games, because as of 2019, Wimbledon has decided to introduce a tie-breaker at 12-12 in the fifth set.

Scotswoman breaks record for touring the world on a bicycle

In Britain, there are not only wonder women in golf. The Scottish cyclist Jenny Graham just arrived in Berlin after having gone on a tour around the world. You may remember that in the Jules Verne novel Around the World in Eighty days, her compatriot Phileas Fogg made it, using trains and steamer ships on 80 days. Jenny did not totally get there, but nevertheless her record is an amazing 124  days! (Another Brit, Mark Beaumont, holds the male record, set in September 2017, with 78 days 14 h 14 min., thus beating Phileas Fogg.)

Donkey steps

On various occasions, I have referenced material from Sveriges Radio (the Swedish Broadcasting Corporation), and here is yet another one:

Yesterday, their correspondent at the EU headquarters in Brussels, Belgium, Andreas Liljeheden, published a chronicle about the particular construction of the stair case between the two main buildings of the European Parliament. The following photo shows exactly that view.

EU steps

As you can see, the vertical displacement from one step to another is small, but the horizontal one is much greater, exactly 1,16 m according to Andreas’ measurement. This makes walking up and down the stairs a complicated task. He investigated the origins of that crazy stair case, and found that in some countries of the European continent, such as Austria and Germany, there is a tradition of using deeper steps, whereas the Belgians and Dutch normally, due to the higher population density, have to settle with a different project, with a higher vertical-to-horizontal ratio. Sweden is, as always, “lagom”, i.e. mid-way.

Here are two more photos of donkey steps, the first one being a close-up of the EU Parliament steps, and the second one a typical scene of donkeys climbing the steps in Fira, the capital of the island of Santorini in the Greek Aegean Sea.

Two examples of donkey steps: To the left, a visitor to the EU Parliament in Brussels, Belgium (photo by Andreas Liljeheden, 2018-10-18). To the right, real donkeys in Fira, Santorini, Greece (photo by Liz Stark, 2016-04-06).

But why is Andreas emphasising this stair case? In no way, he implies that hard working politicians are donkeys, but he thinks it is a symbol for the difficulties encountered by the EU members. If you cannot have a unanimous decision on something by all its 28 member countries (soon to be 27?), then there has to be a compromise, such is life! Thanks Andreas for your valuable contribution!

2018-08-12 (Sunday)

Today, I learned that:

Although the FIFA World Cup 2018 was really a joyful event, one of the best ever, it is once more evident that the slow pace of changes in the rules of the game are detrimental to the temper of many people. So, as I promised in my post of 2018-07-10, here are my 2 cents to make football an even better game:

A very welcome addition to this year’s edition of the World Cup was the introduction of the video assistant referees (VAR) , which made quite a few games more fair than before. Even though it could have been used more often to decide about the outcome of a certain play, it surely made some important contributions to the justice of the games. Here is one such event:

KOR-GER

While the TV image shows a replay of a questionable first Korean goal scored in the final game of group F between South Korea and Germany, the American referee Mark Greiger has been summoned by the FIFA VAR group to revise the play which would result in a Korean lead against Germany in the 93rd minute of the game. He had previously cancelled the goal due to an alleged offside, but the review made him change his decision and confirm the goal. As a consequence, the reigning champion Germany was sent home after the group matches. See also the official match report in reference #1 below .

So, if the referee of the match is the almighty responsible to judge the outcome, even though he might be shown otherwise and still not change his mind, since we now have VAR, why not institute a system just like in the noble sport of tennis?

Most people are probably unaware that in tennis,  the chair umpire, the person sitting in their high chair proclaiming the score etc., is not the ultimately responsible for the outcome of the game. The highest authority, the referee, is rarely seen by the public, but if the players cannot accept the chair umpire’s decision, then they can appeal to the referee, who then makes the final decision. The article in reference #2 describes very well the ruling system in tennis, if you are interested read it through thoroughly.

As you can see from the match report of reference #1, in total there were 11 officials present in the game. My suggestion is, that in cases where there is a fully functional VAR system installed and working during the game, to change the ultimate decision from the referee to the person named as VAR in the match report, i.e. the responsible VAR person of the four mentioned there, and give them the ultimate authority, just as is the case in tennis. If no VAR is present, then of course the referee will still be the ultimate authority of the game.

Another thing that bothers me and many others is the way the extra time (often also referred to as stoppage time) is awarded. At the end of each half of the football game, it is decided how many minutes should be awarded to compensate for interruptions during the game, a very arbitrary procedure. Look at reference #3 which analysed all the games during the group stage of FIFA World Cup 2018. As you can see there, of all the 32 matches analysed, only one game was compensated sufficiently, even overcompensated. It was the game between Germany and Sweden which was 12 s longer than expected. (Maybe as a result of that, Germany also scored the winning goal in the final seconds of the game!)

The worst example of lack of playing time was in the game between Belgium and Tunisia, which should have been compensated by 21 minutes, but only gained 7 minutes extra. The solution is very simple:

Do like in ice hockey, basketball, etc. Stop the watch when no playful activity is going on. Institute 2 halves of 30 minutes each of effective playing time instead of the current 45 minutes halves and the game will be much more dynamic and fair!

There are more things to suggest, such as a more flexible system of substituting players and other matters, but that I will leave that to a future post.

This photo is the first in a series of beautiful, highly defined photos from around the world. In the first round of photos, I will present some of the cities which have hosted the Olympic Games over the years. The first photo shows Sydney, the biggest city in Australia, host of the year 2000 Summer Olympic Games. The photo shows a view of one of its landmarks, the Sydney Harbour Bridge. More about Sydney, the Harbour Bridge and the 2000 Olympic Games can be found in references #4, #5, and #6 below.

2016-01-21 (Thursday)

Today, I learned once more that:

Tennis is probably the most exciting of all individual sports with a ball. Further to requiring that the players are well conditioned to withstand a match that can go on during various hours, they must still remember well the basic techniques and also keep their heads very cool.

When I grew up, my father was secretary of the local tennis club, Herrljunga TK, in a small town with 4.000 inhabitants. Thanks to talented players and dedicated leaders, it even arrived at the top position in Swedish team tennis, beating SALK from Stockholm in the final. And its star player, Jonte Sjögren, later advanced to higher levels, both as a player and leader, being the captain of the Swedish team that won the Davis Cup on various occasions, as well as coaching one of the best tennis players of all times, Björn Borg.

At that time, there were few types of materials used in the tennis courts. The standard material for outdoor courts was a sort of clay, called ‘en-tous-cas’. And of course there were grass courts, such as Wimbledon. To play on one type of court or another meant to dominate different styles of tennis. On clay courts, the ball bounces slower than on grass, so there is more time to get to the ball and plan on how and where to hit it. Of the four Grand Slam tournaments today, the French Open is still clay and Wimbledon, of course, continues with its famous grass lawns. The US Open tournament uses a hard court material, called Deco Turf, and the Australian Open is using another hard court material, Plexicushion, based on an acrylic compound, just like it US colleague. These hard court materials result in even higher ball speeds than the grass courts.

Of course, there are regulations about these materials, and speedwise they are classified into 5 different categories, where category 1, slow speed, includes clay courts. Wimbledon’s grass courts are in category 3, medium speed, whereas USA and Australia are both in category 4, medium-fast speed.

As a consequence of these speeds, a player that knows how to serve well can draw big benefits from the faster court materials, scoring many points on his/her serve and thus leading to shorter times to define the points. I think that this is a pity, because the real beauty of tennis are the long rallies when both players have to vary their shots to defeat the opponent. And now it almost happened again, yesterday!

During the ongoing Australian Open tournament, in the second round, the Czech player Kristyna Pliskova hit 31 aces, i.e. a serve so hard and/or well placed that the opponent cannot even touch the ball. This is a new record for a women’s tennis match at elite level. But even so, Pliskova lost the match to Mónica Puig from Puerto Rico, in spite of the 31 aces and 5 match balls in her favour. Luckily for tennis, Pliskova did not advance to the next round!
