A Translation Mistake with Consequences ?

Since, after the ‘quiet time‘, we are back to ‘peaceful routine‘, it might be quite interesting to stop and think about all the evolutionary changes that even written texts can undergo. This is especially true for the book of books – the bible /1/:

For instance, in early Hebrew versions of the book Isaiah, there is a prophecy that uses the word alma when it describes the mother of a boy whose name is Immanuel (translation: God is with us).

In some languages, among them the ancient Greek, there is no translation for alma. However, a rough equivalent might be “young lady“ or “young lady who has not yet borne a child“.

When Jesus lived, however, the Jews no longer talked Hebrew. They talked Greek or Aramaeic. Consequently, the word alma became the Greek parthenos, which has a specific meaning, namely “virgin“. The biological term Parthenogenesis (“virginal conception“) is based on it: it describes a reproduction process without male contribution as we find it with some insects and reptiles.

That means that a modified translation of one single word turned a “young lady” into a “virgin” and a child into the Messiah! And the story of how Jesus was conceived suddenly changed completely. …

Matthew and Luke even turn this into a truth in their gospels. And for a billion Christians, it turns into a dogma. Which is exactly what we sing about in our Christmas Carols.

Isn’t it strange?

Landing on Antarctica (including travelling report).

Roland landing in the Antarctica.

All participants of an Antarctica expedition have to take part in a preparatory seminar prior to landing. During said seminar, they learn how seriously the world community takes the protection of the unblemished nature of the continent Antarctica.

At the same time, the entire Antarctica, and especially Southern Georgia, is one large museum where many stories of expeditions and science are told. However, it also gives profound insight into the history of this world to geologists.

There are ten rules for landing on the Antarctica and Southern Georgia. You have to strictly abide by them whenever you set foot on the Antarctica and its islands.

  • Please keep quiet!
  • Keep your distance (five metres from penguins, 15 metres from seals and birds)!
  • Do not tread on anything!
  • Never bring plants or animals!
  • Respect protected areas!
  • Preserve historic sites and monuments!
  • Do not take “souvenirs” with you!
  • Respect scientific research!
  • Think of your safety!
  • Preserve the pureness of Antarctica!

That also includes that you must not spit, sneeze or piss anywhere.

Roland on his way back to the ship.

These rules are also meant to protect the animals. I was surprised to see how seriously all participants took them and how they all rigorously kept to what was required.

I, too, got used to never treading onto a green spot. We all avoided unprotected sneezing. It was not possible to accidentally forget a paper tissue.

Thus, each landing became an impressive adventure. The light, the pure air, the wonderful nature made a huge impression on all of us. Historic buildings gave testimony of a horrible industry (waling) that, by promising people good money, had motivated many people to do a gruesome job under the hardest possible conditions far away from home. There were all kinds of remains that revealed quite a lot.

Back in Germany, it really shocked me how thoughtlessly we treat our environment and our nature both on a huge and on a small scale. Even more than before my trip, the pollution of our cyclists’ paths, streets and cities horrified me. The same was true for the gigantic soil sealing of our beautiful country. And of how we, totally without being forced to, expose ourselves to a lot of noise and polluted air in the nice residential areas of our cities.

This is where I also would like to publish a report (Bericht) on the trip for my friends. It was written and illustrated by our great editor Dr. Katrin Knickmeier. She was one (not the only) person from whom we learned so much – and I can also recommend to all of you to visit this special continent.

Solution to Problem 2

On April, 12th, I published a second Logelei in the IF

The question was:
Can you position 31 domino stones (each of which is as big as two tiles) in a square area that consists of 64 square tiles such that two opposing corners remain free?

Solution:
The task is easy as soon as we (mentally) colour the area that consists of 64 tiles like a chess board (Auszeit).
Then we know that one domino stone – as big as two fields (tiles) – will always cover a black field and a white field.

But we will also instantly see that the two opposing fields have identical colours.

So what does this tell us?
If you try to solve this problem by trial and error, you quickly run the danger of making a mistake. However, if you use a simple construct to help you (such as colouring the field like a chess board), the solution will immediately be clear.

You only have to have the right idea!

I am taking time out (Auszeit). This article has been written in advance and will be automatically published (two weeks after the problem was formulated).

Solution

Two weeks ago, I formulated a Logelei I very much like. I also considered it extremely hard to solve. Well, one email I received had the correct answer.

Here is the solution to the problem I gave you on April, 2rd, 2017. I copied the formal part of the solution from the winner: Jörg.
The question was:

How can the criminals make sure that they all survive?

And the solution is surprisingly simple!

Jörg – the winner!

The 10 gangsters have to assign a number between 0 and 9 to every one of them, for instance by counting them down!

As soon as a gangster will see the nine images of all the other nine gangster, he will do the sum of all the numbers on these images and then add “his” number to the sum.

Then he applies the operation modulo 10 to the result and calls the resulting number. Every gangster does this during her or his interview.

This is how you can make sure that exactly one of the gangsters will give the number on his/her picture. The others will, of necessity, say a wrong number – but that is irrelevant, since it will suffice if one of them gives his correct number. That means they all will survive.

Well, as you see, you must never give up hope – once in a while, even mathematics can help.
Here is the formal description of the solution (after Dr. Rothermel).

• Let the number of gangsters be: N
• Let zi be the number assigned to the gangster I (not known to him). It is not necessarily unique and it is part of the set {0, 1, …, N-1} of which a minimum of one needs to be told in the end..
• Let S be the sum of all pre-defined numerals S = Σ zi
The gangsters agree upon the following procedure:
1. Initially, each of them gets a personal, unique number i (known to him/her) assigned to her/his picture from the set {0, 1, …, N-1}.
2. During the interview, every gangster builds the sum of all the numbers he/she can see – that is the (definite) total sum S minus his own (not known to him) numeral zi , i.e. S – zi . That is the only information at his disposal.
3. Since the gangsters are only interested in the numbers in the range {0, 1, …, N-1}, they will modulo N or the congruency relation ≡ N. Now each gangster will calculate an integer x such that:
x ≡ N i – (S – zi ) or
x = ( i – (S – zi )) mod N (I)
With this procedure, exactly one gangster will get his correct zi!

Proof:

S is congruent with a number s from the set {0, 1, …, N-1} or S ≡ N s, consequently, you can also write (I) as:
x ≡ N i – (s – zi )
Since no two N i’s are identical, one of them equal s, consequently, we have for one gangster:
x ≡ N zi.
both x and zi belong to the set {0, 1, …, N-1} which means they are not only congruent, but identical:
y = zi,
and that means this gangster will have the correct number for himself.
(Solution and proof by Dr. Jörg Rothermel)
Now I would recommend that you read the problem  again and ponder it a little bit.

A Very Special Task!

The Solution will be Supplied Later!

A short time ago, a good friend of mine came up with a brainteaser. He did not know the source, otherwise I would gladly have cited it. My friend was not able to solve the problem, neither was I. But it is a truly exciting scenario. And it has a surprisingly simple solution, including a beautiful mathematical reasoning. It also gives us a nice metaphor for our lives.

Among other things, it shows that mathematics can also, once in a while, be quite useful. Here is the story:

Here is a female criminal. On her card, the number 1 is written. But she does not know this. After all, she only knows the nine other images with their numbers.

A – not dislikeable – gang of 10 persons constantly violates the prevailing moral concepts in an outrageous manner. The gang members are creative and wise – this is how, with great finesse, they remain unmolested by the arm of the law for their abominable activities. That is lucky for them, because the legal penalty for their crime is death by strangulation.

In the public perception, the gang soon has a legendary reputation, and is idolized by quite a few simple people. For the authorities, this development is totally unacceptable. Consequently, the increased manhunt of the authorities, along with a growing arrogance and flippancy among the gang members led to the capture of the group.

All 10 gang members are quickly sentenced to death due to their abominable behaviour in a show trial. However, there is a way for the ten comrades in crime to save their lives – through an appeal for clemency. The head of state who decides upon said appeal is a very prudent and well-meaning woman. She is very wise; there are even some rumours insinuating that she may to some extent sympathise with the gang.

Actually, she works hard to come to a fair decision. She hands down a conditional amnesty (a little like a “Judgement of God”):
Before the verdict is executed, the ten members are permitted to see each other once more. There is a farewell meeting, the ten gangsters can spend the afternoon before their execution together and without supervision.

Here is a male criminal. On his card, the number 2 is written. But he does not know that. After all, he only knows the nine other images with their numbers.

As the meeting starts, the gangsters are told how the amnesty will work. A picture of each of the members is taken (two of them can be seen here). On each of those pictures, a number from the set 0 – 9 {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is drawn. Each number can be used several times. Consequently, it is possible that the same number is written on all the pictures. Or that only some numbers are used, for instance {1, 2, 3)}. Or maybe only the even or uneven numbers. Whatever. But perhaps all numbers have been used. Nothing is impossible.

After the meeting, each of them is taken into solitary confinement until the time of execution. Each of the ten gang members is shown the nine pictures of the other nine members – but not his own one. And then they ask him the number on his own photo. And if even one of the gangsters gives a correct answer for the number on his card – all of them will get the amnesty.

Initially, you will think that the gangsters have quite a good chance to avoid their punishment and enjoy clemency over justice. And there is no doubt that their situation will have improved. After all, chances are not too bad that one of the ten will guess correctly and thus free them all.

But it is nowhere near as easy as that. Matters may turn out poorly. And there is one thing the wise regent forgot (or perhaps not): by applying a simple agreement, the ten gangsters can make sure that one of them will inevitably say the right number, as written on his picture. And this is how he can guarantee that he and his comrades will enjoy the amnesty.

It is a small problem: what agreement makes it possible for the gang to use the meeting that was meant as a farewell to make sure that “their heads” are out of the sling with a 100% chance?

I will publish the solution in a few weeks – and until then, I look forward to having many email solutions sent to me!

World-War III

Flag the Islamic State of Iraq and the Levant

Flag of the Islamic State of Iraq and the Levant

There is a lot one could say about terrorism. But in my personal opinion, people mostly write the wrong kinds of things. For instance, much of what I heard and read in connection with the Paris assaults is incomprehensible to me. Many things annoy me, because they seem so flat and un-thought-through.

Also, I am not happy with the reaction to and the treatment of the events and the current situation by our “elite”.

I find it sad that the reasons for this development are forgotten and not asked about either. After all, we have had a strongly developed colonial situation in this world for centuries. The rich countries rule over the poor countries, they exploit and literally abuse them.

Starting during the “long 19th century”, continuing in modern times and still being the state of affairs today, this never changed. The so-called independence of the suppressed did not really improve matters significantly. True, in the 21st century, the methods perhaps look a little more subtle than they were in the 19th and 20th centuries. But this only means they are no longer as obvious as they used to be. However, they lost nothing in efficiency when it comes to the degree of exploitation. On the contrary.

This caused a lot of explosive energy in the world. The politics of the last few decades – incidentally, I am not only talking the West, neither only the USA – served to enrich said explosive energy with fire accelerators. And the time when everything was set on fire with matches was certainly no later than the reaction of the “western world” to 9/11.

But what are the French doing now? Making the same mistakes the West has been making all the time. They throw their bombs with gusto. And probably they will also (and maybe even primarily) bomb civil buildings and hospitals. And consequently also children, women and innocent citizens. As this is always the case with these kinds of attacks. This is how you give extra air to the fire and guarantee new recruits for terrorists.

I also find it annoying to see how different standards are used. Not long before the Paris assaults, the IS bombarded a Russian airplane. More than 200 persons died. Yet, the human fatalities in the Russian airplane were treated with quite a bit of serenity. Where were the shock and the minutes of mourning – and the Russian flags in Europe? To be perfectly honest, until then I had not even known Russia’s colours. After all, I grew up west of the Iron Curtain.

Other attacks, for instance in Beirut, are not even noticed. Because the only reason why we would be interested in those is our yearning for sensational news and catastrophe.

But the attacks in France were totally different. Why? There were huge numbers of solidarity addresses. Silent minutes of mourning were happening all over the place, the avatars on the internet were illustrated in the French colours. Because we are afraid that the same could happen in Berlin or in Munich?

Even as early as on the morning after the attacks, the newspapers boosted it. They talked about World-War-III now being on our doorsteps. When I went to the bakery on Saturday morning, I read a number of these headlines. And the day before yesterday, I read that “the world is now uniting against terrorist“ (SZ of November, 22nd).

In my life, there were many people I knew well and liked who died. Some died of old age and illness. Others remained in the Alps, one never returned from a flight trip.

Ever since my childhood, however, people dying on the streets keep accumulating. They were the largest number and losing some of them really moved me deeply. For instance, I remember a young woman full of life who had spent a very short time at InterFace Computer. No longer than one week into her employment with us, her workplace remained empty on a Monday morning. She had spent the weekend in her home in the Saarland and on the way back, she had suffered a car breakdown. When she exited her car, she was simply overrun on the motorway exit. Just like this. Like an animal.

Are traffic fatalities less painful than war fatalities? Isn’t it strange how we forget traffic fatalities? Why don’t we mourn for the deaths in traffic on a daily basis?

You certainly cannot calculate or balance the pain you feel when a person close to you dies. But I do not think there is such a huge difference between a beloved member of the family being overrun on his way home and the same person being killed in a terrorist attack in a coffee bar.

Consequently, I feel that, indeed, we do have a “World War III“. In fact, we have been having it for many decades. All traffic areas are the current battlefields. Because on the streets of this planet, between 1.3 and 1.4 million people die every year. They come from all social classes and nations. In addition, we have many times as many seriously wounded and wounded. Now if that is not a war, then what is?

In Germany, we still have more than 3,000 traffic fatalities every year. When I was young, there were some years when we had more than 20,000 – in West Germany alone. That means that we in Germany actually made some progress in this war. But we are still far from peace. 3,000, too, are too many. And the number is now again increasing.

If you want to understand what a huge number this is, just go and watch a soccer game with 3,000 spectators. And then imagine all of them lying dead in cars on the streets!

It is quite likely that, in Europe, both fans and players die on the way to the soccer match on each soccer weekend. But who is interested? A few weeks ago, there was at least a minute of mourning at the Augsburg WWK Arena for those FCA fans who had been injured in a car accident on their way to the stadium.

But why do we not have a minute of mourning for our traffic fatalities and those world-wide? Because nobody is interested in the carnage on the streets. And because business has priority. Which, incidentally, is also true for terrorism.

Consequently, there is no international outcry and no important speeches are made by politicians for a more humane traffic. As opposed to the fight against terror, “no world is now uniting” against all the people who died in traffic accidents. And the national governments could not care less, which is totally incomprehensible to me.

There is one exception: the small country Sweden actually takes it seriously and started a Vision Zero, with which they want to definitely reduce the number of traffic fatalities to zero – I bow before them!

The IS, on the other hand, consists of madmen who want to conquer first the Near East and then the world. They built up a terror regime that reminds me of the Nazis. However, regardless of them currently probably being the strongest terror formation, they are quite weak. It would be quite easy to dry them up.

But what do we do?

We buy their crude oil. Because it is less expensive. Thus, every filling of our cars metaphorically contains some IS fuel. They also get their weapons and equipment from us. This is how we get our “oil money” back. And we also provide those criminals with recruits from all over the world. Isn’t that a scandal?

But we block the realistically existing third World War out and also trivialize the climate change. Which actually might easily trigger the fourth World War!

As I see it, there are good reasons to believe the scientists. Especially if varieties of disciplines and schools come up with identical results. It looks like the detrimental effects caused by the climate change will be even more fundamental than the perhaps 75 million traffic fatalities since the end of WW-II.

The resulting environment war would probably be WW-IV. It will probably bring deprivation on two levels. The sacrifices nature demands from us through ever increasing numbers of catastrophes on various levels. And the others, those who will fall in the war between the “early losers” and the “not yet losers”.

And, of course, yet again we hope that we will not be among “early losers“. After all, we are luckily living in a rather “fortunate climate zone”. Now isn’t that rather reproachable? And are you sure that this is not perhaps a misconception?
Yet here, too, there is no chance for shared programs and mutual agreements. Nowhere. Neither nationwide, nor world-wide. Mind you, the environment conference starting in Paris in a few weeks is probably the very last chance to avoid the worst case scenario.

But we ignore the really existing third world-war on our streets as we also ignore the threatening fourth world-war caused by the climate change. To make up for it, we wet our pants with fear of terrorism from an IS that, basically, is actually quite ridiculous. Instead of simply drying them up and dealing with the really important issues.

P.S.
I took the picture of the flag from Wikipedia. It is black, the colour of death. The picture was entered on October, 15, 2006 and downloaded by Russavia.
As I see it, we should beware of black flags. Incidentally, I do not like any kinds of flags. But if you absolutely insist on a flag, then I would prefer the lively, multi-coloured ones!

My “Destina”

🙂 From the South-Sea Island of Runit to Munich Rosenheimer Straße.

„Runit Dome 001“ von US Defense Special Weapons Agency

”Runit Dome 001“ by US Defense Special Weapons Agency

In the SZ weekend edition (July, 4th and 5th, 2015), I found two articles that horrified me. And I posted them as often as possible in Facebook, Google+ and Twitter.

The first article appeared in the “knowledge” sector and was titled: “Dome of Death”. It is about what the 67 nuclear bomb tests executed by the USA between 1946 and 1958 on the atolls Eniwetok and Bikini left behind.

The second artikele  is titled “Extensive Human Tragedy” and tells us about a declaration by the Nobel Prize winners they published during a meeting in Lindau, demanding a fierce fight against the climate change (Klimawandel).

In the first report, the extent of the catastrophe happening in the South Sea truly horrifies me. It again brings back to my mind what a huge danger radioactive waste is. And how small-minded and futile the current attempts to find safe disposal zones in Germany are. Again, politics terminated a project that, de facto, is destined to fail.

I can well understand both the people and the counties opposing a disposal zone. After all, it seems to me that contaminating even more regions on this earth is the biggest possible mistake. Because, naturally, there can be no safety in this area.

Here is another note. The aforementioned article also again mentions that plutonium is one of the most poisonous of all radio-active materials and has a half-value period of up to 24,000 years. Well, in times when we are constantly confronted with billions, 24,000 years seem almost negligible, don’t they? Except – it has been only 2,400 years ago that the first human cultures invented writing – and that is one digit less.…

However, the second article made me almost more furious. In all fields of our lives, we trust science. When we eat food, we trust that science guarantees us healthy nutrients. When we fly, we are sure that, thanks to physics, we will not fall down. We get vaccinations and trust in science. When driving cars, we trust our airbags and even when we ride a bike we follow the laws of science.

But whenever said science provides us with matching results from different disciplines and sources, we do nothing if we do not like those results. My special fury is directed to our current government.

Regardless us of being bankrupt ourselves, they stage a “Western Community of Values” that costs hundreds of millions of Euros in Elmau. And all they can show for it in the end is a few “programmatic decisions” – all of which, even a few days after the declarations, turn out to have been nothing but lip-service.

Germany’s government actually celebrates itself for being the teacher and guardian of public virtue for all Europe and does not even hesitate to come up with slogans such as:  “If the Euro dies, Europe will die”. Incidentally, this is a statement that, like many others from the same source, will not survive dialectical questioning.

For the Greeks, she has a program even the IWF finds totally counterproductive, demanding that they must reduce the retirement money they pay but that they cannot under any circumstances reduce their military budget.

And much more of the same.

Except that she is not doing her homework, for instance by introducing a general speed limit in Germany. She does not put a stop to the gigantic subsidies of company cars. Putting taxation on plane kerosene, too, is something she cannot even allow herself to think about.

And she bathes in self-praise, looking on as infra-structure and education in this country go south. How profits are privatized and losses are socialized and thus how the rich get ever richer while the number of the poor increases along with their dwindling property. To make up for it, she is number one in Europe when it comes to indoctrination and coming up with stupid dogmata.

That is when I occasionally start asking myself if my “destina” might not be to fight all this stupidity and counter-productivity. But that would mean I have to stop doing what I am currently doing, namely linking and mentoring persons and supporting start-ups. And I have not yet quite reached that stage.
