YouTube Video – Putting the Middle Ages in Perspective

I really like videos made by Ian LaSpina who goes under the handle Knight Errant on Youtube. They are short, to the point and are packed with well researched information (at least as far as I can tell). In this video he explains how Middle Ages were not stagnant from technological point of view and progress was being made.

Anatomy Atlas Part 2 – Lower Limb Skeleton

Colloquial Czech does not distinguish between a foot and a leg. The word “noha” normally refers to the whole limb from the hips down. Medical terminology differs from this and the word “noha” means only the foot, and “dolní končetina” is used for the whole limb. Professor Kos has hammered this point home throughout multiple lectures and we were suspecting that if someone were to use the term “noha” in its colloquial sense during an exam, it would be an insta-fail.

Legs and feet are our means of movement, so they are very important. It is therefore important to look after them. Which, regarding the bones, means adequate exercise and not more than the body can handle.

What ordinary people do not usually know is that bones are not fixed structures. They are consumed from within and regrown throughout our lives. That way they can heal, but also change shape. That way they can also get injured in a rather peculiar fashion.

One of the stories Professor Kos was telling was a story of “march fractures”. Fresh army recruits, especially those from cities who were not accustomed to walking a lot, were often complaining about pains in their legs and feet bones after long marches. Initially they were deemed as pretenders becaue the x-rays looked normal, but some of them broke their legs when forced to go on. Then someone took a magnifying glass to an x-ray of the alleged pretenders legs and feet and noticed microscopic fractures developing before a clearly visible fracture occurred.

These are so-called fatigue fractures and they happen when a bone is deprived of nutrients. The bone continues to be consumed at a normal rate, but it does not manage to regrow back fast enough. Over time these tiny deficits accumulate and the bone starts to hurt and can even break.

A colleague of mine has developed just that in her foot during nordic walking strolls that were just a bit too much, too sudden and too long for her. It took a few weeks to develop and over a year to heal, with a surgery and a very long rehab being necessary.

Too much exercise is just as bad as none.

Behind the Iron Curtain Part 2 – Education

These are my recollections of a life behind the iron curtain. I do not aim to give perfect and objective evaluation of anything, but to share my personal experiences and memories. It will explain why I just cannot get misty eyed over some ideas on the political left and why I loathe many ideas on the right.


I was born towards the end of summer, which effectively means I was almost a year younger than many of other kids who were supposed to go to school that year. This has led to concerns whether I will be mentally mature enough to cope so I was brought in for preliminary evaluation in the spring prior to my first school year. I do not remember almost anything of it, only that it was a pleasant conversation with some old lady whom I did not know.

After I was deemed eligible, the education started. It was pretty normal as an education anywhere else at that time. Children sitting in rows in cheap, uncomfortable chairs behind small tables. Teacher standing in front of the class talking. Don’t talk unless asked, raise your hand if you want to say something or ask.

The regime had somewhat ambiguous attitude to education. On one hand it has recognized that knowledge is empowering and completely ignorant and uneducated populace is useless. Therefore eight years of elementary school were compulsory and the regime took pride in nearly universal literacy and numeracy.

On the other hand it has also recognized that educated and well-informed people are harder to control because they have that unpredictable tendency to be critical of the information presented to them and reach their own conclusion. which has proven correct, since the velvet revolution was initiated by massive student protests.

So the higher education was theoretically available to anyone who was capable, but there were caveats that had nothing to do with capability and everything to do with how much one was perceived to be a threat.

Ever since childhood I was recognized as a university material. I was top of the class and despite year-long health problems that impeded me significantly for a few years I did not need to repeat classes. My father was a member of the communist party and of Peoples Militia, and he was working class. This was considered a good thing in my yearly evaluations and was always mentioned together with my good notes. However one of my uncles was a political dissident who has emigrated to USA and was in the employ of US government. This was considered a bad thing although I was never told this and I only learned about this later on. Further, by a twist of destiny, my father, the communist, was the only one from the family who remained on good terms with his dissident brother. So there was always a big question mark about my future education and whether I will be allowed to pursue either my love of science or my passion for painting.

The regime seems to have had some sort of poorly thought out and poorly formulated concept of hereditary sin. Children and even grandchildren of aristocrats or bourgeois or anyone really even remotely related to dissidents were treated as a threat and were put under close scrutiny. As I grew older I learned about this and I have tried to understand it but I never did. It did not make any logical sense to deny someone higher education just because their grandfather was a bourgeois factory owner. They are not factory owner, they live in this wonderful socialist country where everyone is equal just like everyone else. They did not do anything wrong, their grandfather did. Where is the logic in this?

That way I learned there is another iron curtain in addition to the corporeal one in the forests. An invisible social barrier creating a tangled maze nearly impossible to navigate, because the rules were never clear and were subject to the whims of the powers that be. There was only one sure way to higher education, and that was being a relative of a high party affiliate. Everyone else could be denied for reasons they will never fully learn.

Luckily for me when I was a the end of elementary school, the regime fell and the Iron Curtain was torn down. And with it fell the artificial barriers that might prevent me from getting adequate education. There were other barriers still and new ones emerged, but that is a different story.

I Cannot Tell a Lie – I Chopped Down The Cherry Tree

But I really did not enjoy the task.

My father has planted this tree for me when I was about 10 years old. I liked cherries back then. Now I cannot eat cherries any more, because for some reason they cause me hypoglycemia which is really unpleasant. But I enjoyed the blossoms in the spring nevertheless, I always looked forward to them and I did not mind the birds eating all the fruit at all.

I did not take any pictures with my new camera last year, so I can only share pictures that I made with the old one in 2012.

Last fall mushrooms sprouted on the trunk and that is a really bad sign. There are two kinds of wood in a tree – sapwood, which delivers nutrients from roots to the crown, and heartwood, which is usually more dry and dark and is essentially blocked off and completely dead. Accordingly, there are two types of fungi that can attack wood on a living tree – ones that attack the sapwood, and ones that attack the heartwood. Have a guess at which of these two is more dangerous.

If you like me during my studies guessed those that attack sapwood, you guessed wrong. Fungi that attack sapwood will cause the tree to wither and eventually die, but the tree remains standing relatively intact afterwards for long enough to be felled safely. However fungi that attack heartwood are more insidious – the tree can grow for many more years at absolutely normal rate without anything really visible on the outside. And then, when enough heartwood has rotten away, a branch will suddenly snap, or a the trunk will spit or break. And this of course is dangerous, because to an untrained eye the apparently healthy tree is essentially a ticking bomb that can kill someone at any time – which is something that has happened in CZ a few years ago and it has made the headlines. Heartwood is dead and dry, but it still has a function – it is the scaffolding that holds the tree upright and together.

This tree has developed a split in the trunk at about 10 years  age. We were doing our best to keep fungal infections away, but the split never closed off and we were evidently unsuccessful in the end. I was not able to take a good picture of the mushroom, because it lasted only a few days, none of which was on a weekend. I was unable to determine the exact species too. But I was confident enough in assessing that it is a heartwood eating fungus. So I decided to fell the tree before it becomes dangerous to do so. The tree was huge, so all winter I have cut branches when I could. They were all still healthy and I started to have doubts. But this friday I have finally cut the trunk right above the ground and my assessment of the situation was confirmed. The fungus has already invaded the inner 10 years growth and was spreading. The tree would probably live a few more years, maybe even a decade, but I do not think it was worth the risk, since I do not know how fast the fungus spreads.

I have felt real connection with that tree. I was hoping for it to live longer and age with me. If I ever feel something that could be described as a spiritual experience, it is in the presence of a tree in the spring.

I will plant a new cherry tree on the spot as soon as possible.

A Few Spring Flowers

I took my mother yesterday to visit her sister, my favourite aunt. She has a really exquisite garden, but unfortunately the spring is not that advanced here yet to see it at its best. And I also have forgotten my camera, so I could only make pictures with my phone. Which sucks, but I think they still are worth looking at. Click for full size.

YouTube video “People who like martial arts and weapons are normal”

Well, some of them are. Some are assholes and some are downright dangerous. And some are capable of formulating comprehensive (though not perfect) argument for their point of view. I must say that I too don’t find watching people kicking spherical object around the field for 90 minutes even remotely entertaining.

However if we take “normal” in this context to mean “not different from any other group of people” then I would say the title is completely correct. Assholes and dangerous people are in any and all human congregations. The compounding problem here is that while a dangerous footballer will at the worst hurt one o their fellows on the playing field, a dangerous person with a gun can do much more damage.

I think I could have a reasonable discussion with Matt Easton, author of this video and I think he missed slightly a good opportunity to enhance his point by not wearing his “Fighters Against Racism” T-shirt in this one.

To me this is another issue that is not clear-cut black&white. We have a saying in Czech “Když dva dělají totéž, není to vždy totéž.” – When two (persons) do the same thing, it is not always the same thing.  It applies here.

The key difference is the attitude and intent. Weapon collectors will grumble about laws that restrict their hobby, but most of them will respect the law and for example limit their collecting to weapons of the type that is legal in their country and they will buy ammo and shoot only a the shooting range for example. They will not found and congregate in corporation-like organizations lobbying for complete abandonment of said laws . They will not amas  a load of super-modern weaponry and pallets of ammo to go with it. They will hunt the rare, the peculiar, the unique pieces.

It is possible to appreciate weapons for their aesthetics and technical intricacy and enjoy learning the skills to use them without ever hurting anyone, or ever wanting to hurt anyone. And it is possible to pursue such hobby even in a country with strict gun laws – only, like in any other hobbies, other people’s needs have to be taken into account and respected.

Easter gingerbreads

We do not celebrate any religious holiday, but they are a good excuse for my mom to go on a gingerbread-baking spree. They are beautiful and delicious, and each year she comes up with new designs and styles. I do not know how she does it.

Anatomy Atlas Part 1 – Spine

This first in a series of human anatomy sheets that I have drawn during my studies.  As future biology teacher I had to acquire some basic knowledge about most of biology – sort of  jack of all trades, master of none. However our class was one of the last where human anatomy was taught by a prominent Czech physician and scientist Profesor MuDr. Jaroslav Kos. He was eighty years old at that time and it was showing, however he still was formidable and very strict. I failed my first exam miserably, I do not even remember what the theme of the examination was. I think brain stem? Nevermind, it took me two attempts to pass and for the second attempt I really sat and learned latin like my life depended on it. He did not even let me finish on my second attempt  and waved me away with top grade after I described how  nervus olfactorius consists of multiple separated fila going straight through lamina cribosa directly into the bulbus olfactorius of the brain. I forgot most of my medical latin over time, but I still remember this.

A fun fact about spine – the “S” shape of our spine and all accompanying problems it brings stem from the fact that it originally evolved for movement in water and later on land with lateral undulations, which was later yet modified for movement on land on all four with vertical undulations, which was even later modified for upright movement on hind limbs only. The spine was definitively not intelligently designed for vertical posture and load bearing. Evolution has done its best, but that is always “just enough”.

This is a coloured sketch to one of my paintings. I cannot unfortunately make a picture of the final painting, because I gave it to my brother who now lives 400 km from me. All the paintings I gave him are at the moment not fulfilling their function, because my sister in law has stashed them away.  They “do not fit with the color scheme of their new appartment” which I did not take kindly, because they could keep the paintings during the renovations in mind if they wanted to. Click for full size.

A bummer – I have just reminded myself that a lot of my sketches are ruined or damaged. A few years ago I was reconstructing the roof and the workers have moved my stuff around without heeding my instructions. The impromptu cover was also built sloppily and my warnings that I live in very windy area were dismissed as needles worrying of an amateur. Inevitably the drawings were stashed under the impromptu cover which got ripped off in a gust of wind. And rain poured on them. I only found out a few months after they left, when everything was mouldy.

It would take a lot of time to airbrush it in Photoshop, so some of the pictures will unfortunately have maps on them.

Behind the Iron Curtains Part 1 – Growing Up

These are my recollections of a life behind the iron curtains. I do not aim to give perfect and objective evaluation of anything, but to share my personal experiences and memories. It will explain why I just cannot get misty eyed over some ideas on the political left and why I loathe many ideas on the right.


Kids are kids everywhere, at least when they are not dying from malnutrition. In at least somewhat functioning society they like to play, run around and nag their parents with incessant questions about the mundane as well as the profound. “Mom, why is the grass green? Mom, why does rain fall down? Mom, what is a whore?”

Children in eastern bloc behind the iron curtains were not different. We liked to play and chat, and we did so whenever possible. But one thing that many children from that time shared, some more, some less was fear.

Fear of nuclear annihilation.

Later in life I learned that people in the West were afraid of those evil aggressive USSR commies who wanted to wipe them out and were held in check only by superior military power of magnificent NATO. Well, on our side of the border it was those trigger happy evil capitalists led by evil imperialist USA who were held in check by superior military power of magnificent Warsaw Pact. And in reality both sides committed war crimes and atrocities, there were no angels in the hot spots of the cold war.

Adults might have had their doubts and objections regarding the veracity of all this fear mongering, but for kids it was definitively all real. The regular “fallout drills” at school, regular alarm drills, signs how to react in case of nuclear attack hanging in every office. Once we were playing with my cousins in the garden and we heard a noise from the sky we did not know. What instantly gripped us was the fear that these are the nuclear missiles heading for Prague. Where I live this feeling was exacerbated by the very real presence of the iron curtains.

From every window of my house I see across the border to Germany. If I were to walk in a straight line in any direction from my property, I will end up in Germany within a day’s walk. Going mushroom hunting was allowed only in certain directions and certain areas of the forest were taboo. Big signs “Caution, State Border Ahead” everywhere. I still remember that one of the signs was riddled with bullet holes. The only time in my life I have seen a real thing riddled with bullets

And the curtains themselves…

Due to the signs and restrictions on movement, they were not usually seen in person and I never touched them. Mostly I knew they are there, somewhere in the forests. But the train track was driving very close o them, so whenever we were riding train to visit the inland, I could see them from the window.

Three meters high, double fence of razor wire. Roundup sprayed shooting corridors. And a macadam road for easy military access.

To a child, that was a terrifying sight. I loathe to see such structures being build again.

A very brief introduction

So. Testing, testing. Is this thing working properly?

  1. one
  2. two
  3. three

Caine asked for some help with blog content and after a consideration I offered to do it. She has handed me the keys to her blog and I will do my best to not scratch it. Hopefully my blogging skills are better than my driving (you really would not like to lend me your car, and I would never accept it).

Most people reading this blog know me already from comments. So just very briefly who I am:

I am male, Czech, living in CZ. First third of my life I lived behind the iron curtains – literally. After it fell I graduated in teaching of biology and chemistry, and I also briefly studied psychology and arts. Currently I am working in Germany and in the course of my work I often find myself in situations like in YouTube sketch “The Expert“.

You are free to guess who I can relate the most with. I have already once said about one of my managers that he is an incompetent buffoon with whom I refuse to work. I expected to be fired after that, but instead the boot has hit his ass.

My hobbies are gardening, photography, woodworking and knifemaking. In the past I was also drawing and painting, but alas I do not have time for that anymore. But I hope to have again sometime and I will post some of my former works. I was not magnificent, but I have on occasion managed to do a decent job of it.

Thinking under a tree

Politically I am left of center in my country, but I would be considered to be a radical leftist in the USA.

I consider the most important skill to have to know when to shut up. It is also the most difficult skill to acquire and hone.
