In a society that does not seem to be interested in protecting their citizens against lethal dangers, which is the new trend? Instead of using the year 2021, they keep on insisting to still use 2020, as if it did not already exist. Currently, there are at least three big sporting events that were cancelled in 2020, due to the COVID-19 pandemic, and that just happened or are about to happen, and which keep 2020 in the name.
Please look at the following image. More information about the events can be found in references # 1, 2, and 3 below.
We have experienced yet another interesting month in our lives, and what follows below is of course only a small portion of what I really wanted to publish.
Complement to my post about Vasaloppet
In my post of 87’2021 (2021-03-28) , I wrote about the traditional ski race Vasaloppet. It starts in the town of Sälen and ends in Mora, 90 km away. One of my faithful readers sent me a nice picture from the same Sälen, where he recently enjoyed a different kind of skiing, going downhill. You can see it as the header photo of today’s post, taken at the peak Hundfjället (“Dog mountain”).
Making it easier to deal with the proposed numbering of days
In my post of 9’2021 (2021-01-09) , I suggested that we started to think about a new, unified way of writing dates, abolishing the months and changing to a sequential count of the days in the year.
Many people have expressed their support of the proposed scheme, but raise doubts about how we more easily can get used to it. Therefore, here is one way, turning the cell phone’s lockscreen into a monthly calendar, with both the current and the proposed day count and making it also function as a communications tool between peoples and languages.
Also the month of March has been quite interesting with some things that can only happen this month. Here they are:
The first Thursday of March
Although this special day started to be celebrated a decade ago, I only learned about it this month. It is a kind of unofficial local holiday for the Swedish landskap (province) of Småland in the South East of Sweden. I already spent five months of my military training there during the 1970s and so of course I had already notice that the locals have a big difficulty in speaking the combination of r and s in Swedish words. In normal Swedish, this is pronounced as a so called supra dental, where the r and s flow together. However, in Småland, that is not the case, they pronounce it as a sound containing two s’s. A linguistic explanation (in Swedish) can be found in reference # 1 below. It is linguist Jenny Öqvist at Institutet för språk och folkminnen (Institute for Language and Folklore) who has broken the sounds down into minute details. She also took the following photo of a cake served on this special day. It is a popular sponge cake in Sweden, with whipped cream and vanilla in between the layers, with a topping of marzipan, normally known as Princess cake, due to its connection with three Swedish princesses in the 1930s.
A man from Småland named Jonas Svenningson came up with the idea to start celebrating the pronunciation of ˜första torsdagen i mars˜ (meaning the first Thursday of March) in Småland as particularly interesting, because it is ˜fösta tossdan I mass˜. The idea spread like wildfire and now it is celebrated as Småland’s local, ˜national day˜.
The first Sunday of March
In my post of 66’2016 (2016-03-06) , I wrote about the traditional Swedish ski competition Vasaloppet, which is held every year on the first Sunday of March. This year, due to the on-going pandemic, only 400 selected top athletes could participate and what a race they made! The excellent weather conditions, well prepared tracks, sunny weather and -6 degrees Celsius resulted in that both the male winner, Tord Asle Gjerdalen from Norway, and the female winner, Lina Korsgren from Sweden, broke the records for the race. More details can be found in reference #2 below.
Sweden’s floral emblem
Each of the landskap (provinces) in Sweden has its own flower, but so far there had not been any national flower for the whole of Sweden. Until now!
Svenska botaniska föreningen (Swedish botanical society) invited the Swedish population to vote for their favorite flower. In the first voting phase were selected ten candidates, which participated in a final round to decide the winner.
And the winner is:
Liten blåklocka, Latin name Campanula rotundifolia! See also reference #3 below for more details.
The Öresund bridge
And last, but not least, my sincere thanks to my friend Graziela Gabrielli, who so graciously gave me her permission to publish the beautiful photo she took from the Swedish side on the high summer day of 197’2019 (2019-07-16), showing the bridge that since 2000 connects Sweden and Denmark over the straight of Öresund, thus called Öresundsbron (Öresund bridge).
More about Öresundsbron can be found in reference #4.
During the month of February, there have been some quite interesting things I have taken notice of. Here are two of those:
Railway on pillars
In my post of 33’2016 (2016-02-02) , I made a comparison between electric circuit theory and the then on-going process in Sweden on how to choose which routes would benefit from a planned high speed train network. That planning still goes on, but many people are scared about the costs involved and the time it will take until the network would be available for public transport.
Now there are rumours that the responsible authority for the project, Trafikverket (the Swedish Transport Administration) finally has started to make calculations using not the conventional rail system on flat land, but thinking about the advantages of constructing an elevated system, using what they call landbroar (“land bridges”). So I ask, what is new with that concept? It has been used for more than a century around the world, think of the Loop in Chicago, the elevated railways around New York City, even on various places within Sweden, such as the Stockholm subway.
And as I wrote in my post of 101’2016 (2016-04-10), in April 2005 I spent almost a week in Shanghai on a business trip, where I also had the chance of doing quite some tourism. I did not show it in my blog then, but during those days Shanghai was also executing the final tests of a magnetic levitation train of German origin, called Transrapid. It was built to transport passengers between the Pudong international airport and downtown, a 30 km distance which takes only 7 minutes. Since the operating hours during the trial period were restricted to some hours during the day, I did not have the chance to ride the train, but in the following picture you can see it en route on its elevated railway.

You have probably heard about the Swedish physician Hans Rosling, who was a fabulous lecturer on matters that should interest every one. Together with his son and daughter-in-law, he wrote, among many other things, the book “Factfulness: Ten reasons we’re wrong about the world – and why things are better than you think”. If you have not read it, then you do not know what you are missing. Look up the book online and buy it immediately! It will be an experience you will never forget! Unfortunately, Hans Rosling died in cancer in 2017, but during this month, one of my students of the Swedish language sent me a link to a very interesting series published by the Swedish public service television SVT. Thank you Graziela for that hint! More about Hans Rosling and his amazing book can be found in references # 3 and 4 below.
So, in the wake of Hans Rosling, one person who has picked up his role is Anders Hansen, a Swedish physician and psychiatrist. He wrote and presented a series called “Your brain” which presents some mind (sic!) blowing facts about this organ, with the physical size of only two clenched fists, with an extraordinary capacity to control everything we see, hear, taste, feel and smell. SVT has now published two seasons, with a total of ten episodes, in their SVT Play online. Do not miss it, it will be removed in the beginning of the second half of 2021. The series is entirely narrated in Swedish, except for the various interviews in English that Anders Hansen performs with world famous specialists on site in San Francisco, San Diego, Oxford etc. But if you use the web browser Google Chrome and its function Google Translate, then you can enjoy the whole series with subtitles in the language of your choice. More about Anders Hansen in reference # 5 below. The URL of the series and detailed instructions about choosing the preferred language can be found in references # 6 and 7.
Once more, here we are, on the anniversary of my blog. And today, we are celebrating five whole years! Thank you all who participated on this journey, both those of you who read the first blog post and decided to stay and those who have joined me and my followers later on. THANK YOU !!!
There is a link to the very first blog post in reference #1 below.
It’s time to start a new way of counting the days!
As an anniversary present, I would like to make a proposal to make it easier to write dates. In my second blog post ever, I wrote about how different it is over the world, and although there is an international standard, which was adopted in 2004, there are few people that use it. If you are curious about how that standard is, look up the link in reference # 2 below.
I have had quite some ideas about how a new system for counting the days could be implemented, but what really made me going was a post on the Quora site, that I read some time ago. It was written in 2016 by an American professor named Dave Consiglio. Thank you, Dave, for your excellent ideas! See his thoughts in reference #3 below.
In line with Dave’s ideas, I created a way to write days that everyone could adopt, easily. You can see the notation in the headline of today’s post. Basically, it abolishes the inconsistent system of months and considers the year as the main unit for counting the time, subdivided only into 365 days (or 366 days in a leap year). Each day would consist of 10 subunits, named Planck, as a tribute to one of the greatest scientists of all times, Max Planck.
See my proposal in detail in reference #4 below and details about Max Planck and his works in reference # 5.
This month, the last one of the year in Western time keeping, has got some interesting facts that you may not know of. So, here they are:
Saint Nicholas’ Day
Today, December 6, is known as Saint Nicholas’ Day. It is a tribute to the Greek Christian bishop Nicholas of Myra, known for miracles and giving gifts secretly, who died on 343-12-06, and is now the patron saint of little children, sailors, merchants and students. In Germany, it is a tradition to put a boot outside of own’s house on the evening of December 5, so that Nikolaus (as he is called in Germany) can stuff it with treats. But do not put out both boots, you may seem too greedy!
Saint Nicholas is of course the origin of the name Santa Claus, who comes in person to deliver gifts on Christmas Eve. See also reference #1 below.
Interesting facts from Finland
Exactly three years ago, on 2017-12-06, I wrote about the centennial of independence of Finland. My mother’s family had roots there, so I was accustomed to hear the greeting “Hyvää joulua” (i.e. Merry Christmas) when the time was right, but I had not idea that the whole month in Finnish had a direct linguistic connection.
Whereas many Western languages base there naming of the months on Latin traditions, in Finnish, which belongs to a different group of languages, they have a totally different scheme. In that sense, the month of December is called “joulukuu”, which literally means “Christmas month”. And as you can see from reference #2 below, the other months of the year are also different, basing their names on different events in nature.
We have come to the end of yet another interesting month. Below are some interesting things that caught my interest:
On 5G, Covid-19, cocksureness and today’s challenges
My alma mater, Chalmers University of Technology in Göteborg (Gothenburg), Sweden was founded on 1829-11–05. And each year since 1991, around this day, there is a lecture about popular science, the William Chalmers lecture, held by a prominent researcher. This year, it was Erik Ström, professor at the Department of Electrical Engineering.
Erik leads a team which has participated in developing the modern day communication technologies, all up to 5G. And now it is planning the development of the successor, 6G. Erik talked about that, but also about the omnipresent Covid-19 and how one can estimate the probability of having the virus if the test result is positive, etc. All this was done in a very leisurely style, I am sure you will enjoy it as much as I did!
See references #1 and 2 below for all details.
What does bimonthly mean?
If you learn that a certain measure should be taken bimonthly, what does that mean? Should it be twice a month or every other month?
The answer is that it could be either way! You have to find out by the context, if you can.
See also reference # 3 below.
What is round and attracts the automated video recording system?
As we all know, technology of all sorts are so developed nowadays that many things can handed over to automated systems and they take care of them brilliantly. But there may be glitches…
The Scottish football club Inverness Caledonian Thistle FC employed an automated video recording system to transmit their games online to their fans who were locked down at home. The system was programmed to keep track of the ball. It worked fine until a certain day the system confused the ball in the field with one of the linesmen.
Something very interesting happened earlier this month:
Researchers at the University of Rochester demonstrated that a compound made of carbon, hydrogen and sulphur is able to carry electrical charges with no electrical resistance at such a high temperature as 15°C. This temperature is much higher than what any proven superconductivity has been performed at before.
There is however one catch. This demonstration could only take place because the material was under a pressure of 275 GPa, which is almost three million times higher than normal air pressure. But the research team is working on that, through a special technique called “compositional tuning”.
If they will be able to make this material more economical to produce, then it can lead to power grids that save millions of MWh, faster electronics and new ways to propel levitation and its use in transports.
More information about this exciting discovery can be found in references 1 and 2 below.
Before going over to some interesting updates to earlier posts I have made, some words about the fabulous header photo. My friend Gustavo Winckler recently visited Gothenburg with his family. They got really amused about this cosy city, and who would not? You may remember my post of 2017-02-28, where Gothenburg was called the world’s best city regarding the social behaviour and attitudes of its residents.
His wife, Tatiana Winckler, took the photo in a central park from the 19th century, called the Garden Society of Gothenburg. This particular photo shows the Palmhouse and some nice treats at this time of the year. Thank you, Tatiana, for illuminating our world with this amazing photo!

Updates to earlier posts
Flying boat made of cashews
In my post of 2017-06-23, I wrote about a boat developed by researchers at Chalmers University of Technology in Gothenburg, Sweden, which rides over the waves at astounding speed. And now they have done it again!
This time, 30 Chalmers students from different grades and educational tracks constructed a flying boat made of cashews to compete in the sailing race 1001VelaCup in Italy. Due to the COVID-19 pandemic, the race was cancelled, but the boat won the replacement design competition. See the photo below and reference #4 further down.
Solar energy in EU project
In my post of 2019-12-31, I wrote about a groundbreaking use of solar panels in a system to store and retrieve energy. Now that project is on its way with developing prototypes for large scale applications. It has been awarded an EU grant of 4,3 million Euros for a start.

Video clip of Gripen’s presentation to the public
In my post of 2020-09-22, I wrote about the arrival and first days of the Swedish multifunction airplane Gripen E in Brazil. Now you can also see a video of its official presentation during the Aviator’s day in Brasília on 2020-10-23.
Earlier today, two very interesting events happened. Although there is no formal connection between the two, both include Sweden and Brazil, a plane and no cars! If you think that it sounds strange, then see below how they are interconnected:
World Car Free Day
Ever since year 2000, September 22 is celebrated as the World Car Free Day, where many cities close their centers to not allow any cars, giving way to pedestrians and bicycles. I had the pleasure of participating in an online event organised by the Swedish embassy in Brasília dealing with Vision Zero, how to organise the traffic in order to reduce the mortality rate, ideally down to 0.
More information will follow in a coming post. In the meantime, see references # 1 and 2 below.
Gripen finally in Brazil
In my post of 2019-08-27 , I wrote about the first test flight made by the Swedish fighter jet Saab Gripen, which is on order from the Brazilian Air Force. And now it is here in Brazil! It arrived by ship last Sunday, and in the early morning hours today, it took advantage of the absence of cars and was transported by road from the port of Itajaí to the neighbouring airport of Navegantes, state of Santa Catarina. There it will be fully equipped and tested, before it will make its maiden voyage to the Embraer plant in Gavião Peixoto, state of São Paulo.
Also, here I have more information coming up in a coming post. For now, you will have to wait by watching the photo below and the information in reference # 3.
Yesterday, the first Gripen E made its maiden Brazilian voyage. In the photos below, you can see its take-off from Navegantes and landing in Gavião Peixoto. Also, in reference #4 below is Saab’s press release about this historic event.
Thanks to Saab, Embraer and FAB who made all this possible!
There are so many interesting things happening outside our small Earth, in the vast space of the Cosmos. I recently took a course on the edX MOOC (massive open online course) from the mighty MIT, Massachusetts Institute of Technology. The course had the title “Introduction to Aerospace Engineering: Astronautics and Human Spaceflight.”
What made the course so exceptionally interesting was, besides the contents with plenty of video clips further to the traditional Power Point style lectures, that the teacher of the course was no one less than an ex-NASA astronaut, Jeffrey A. Hoffman. His first space flight was in the first servicing mission of the Hubble telescope in December, 1993, and after that he participated in four more missions to the international space station ISS. Only a live astronaut can make a course like this even more interesting by telling his personal experience of those missions. See also reference #1 below.
Another interesting fact about the big wide space was published in June, 2020, by Popular Mechanics. It is a story about how a pulsar prepared itself to eat up a nearby star and released an outburst of cosmic X-rays thousands of times brighter than the sun!
