Not an Alien Facehugger.

The crab spider on our Sunflower has grown pretty big and fat. The diet of bees apparently suits it well (I have seen it to eat another unfortunate bee).

I think this picture shows how the spider manages to subdue much bigger prey without falling off the plant with it during the struggle, although I have not had the luck to see it in “action”. You can see that the spider has built a small web and has thus essentially tethered itself with spider silk to the plant. Ingenious.

The Handmade Dilemma

The heat is killing me. Temperatures outdoor during the day over 35 °C, overnight never lower than 18 °C. Temperatures indoor 28 °C throughout the day and there is nothing I can do about it – if I open the windows wide, the house will be swarmed by mosquitoes in minutes. I have nets, in some windows, and in normal weather those suffice for ventilation. Not in this weather though.

So works on the dagger progresses at a snail’s pace. Not that it matters much, because snail’s pace is also the speed at which linseed oil hardens. But it means it is unlikely I will have anything to post about it anytime soon. However, that does not stop me thinking about stuff and one of the things I am thinking about – will it be fair to say, that the dagger is handmade?

In the past, when I have made a knife, it was truly and undoubtedly handmade. The only electrical tool I had was a drill that I used to make holes for pins. Everything else I had to do manually, with hand-held and hand powered tools, whereas today I have a table top belt grinder, handheld belt grinder, an angle grinder, a lathe, a bandsaw, a circular saw and a jigsaw. And in due course I intend to build a power hammer and a polishing drum.

And I do not spare any of those electrical tools. If I can save time or my muscles by using electricity, I do it without hesitation. But there are some purists, who would argue that therefore things I do are not handmade.

I disagree with that.

The way I see it, these electrical tools are nothing but providers of raw power. They do not provide or increase any skill – all that still has to come from my hands, because ultimately they guide either the tool or the workpiece during work and therefore determine its quality. In fact, some of the tools – especially the belt grinder – require a slightly different set of skills to do the work properly, than doing the same work with bastard file and a set of polishing stones would.

So I think the dagger is handmade. And purists can go and purify themselves.

 

 

Anatomy Atlas Part 18 – Arm Muscles

I mentioned that hands are a marvel – and so are arms. However the muscle structure is a bit weird.

If you have ever wondered why biceps are called biceps, now you have the answer. The musculus biceps brachii splits into two parts on the upper end  and each is attached to a different part of the shoulder-blade. Whilst it its the most prominent muscle and its development is seen as a sign of strength, biceps is not the strongest flexor in the arm. That is in fact musculus brachialis which lies underneath, connects to ulna it and generally is not seen very much.

Professor Kos mentioned that this arrangement of these two muscles leads to one peculiar thing – flexing of the arm can exert more force when done palm up, than when palm down. Why? Because when the palm is directed down, the musculus biceps has its load bearing tendon wound around the radius to which it is connected. Therefore it cannot flex without also trying to turn the hand palm up.

So when lifting things by flexing your arm palm-down, only two muscles – m. brachialis and m. brachioradialis – can exert force, whereas palm up the m. biceps can join for more strength.

Why is it like this I do not know, but had it been designed, the engineer would deserve at least a pay cut.

Behind the Iron Curtain part 14 – Greyness

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.


Coincidentally my mother mentioned to me that she overheard some talk about people who emigrated from here before the fall of the Iron Curtain, and this year was the first time they visited since then. Allegedly they were speechless when they saw the town.

I find it totally believable, because independently from this I was just thinking about the same – how much the country has changed, visibly, for the better since then. Because if there is one overwhelming association that I have with the “good old times” as some people insist calling them, it is an overwhelming sense of dullness, and not because we mostly have black and white photographs and movies from that era.

Today people are used to simply go and buy things they need. Want to plant flowers in your front yard? Well, you can buy them! Want to paint house bright yellow? Well, buy the paint! That was not always the case. I have already mentioned the scarcity of even some basic goods. And those that were available, were often (not always) of questionable quality, because high quality goods were exported to the west so the regime can actually make some money to run itself.

So most buildings were grey on the outside, no matter whether public or private. Not that it was always intended to be grey – privately people did sometimes at least whitewash the walls, and public buildings occasionally had some not very bright pigmentation in the plaster. But no matter what one did, in a few years time it has turned grey-ish due to the ever-present air pollution and dust. So many people, and most of public projects, did not bother and the favourite finish for facades became so-called brizolit, cheap, durable, low-maintenance and, above all, dull and grey.

Private house owners did what they could at least with the gardens – sometimes. It took real dedication for years to build, for example, rock garden, like one of my aunts had. But even the flowers could not fight against dirt and their bright colours did not last for more than a few days at best. And getting new varieties or replacing dead plants required connections, because, you guessed it, you could not simply go and buy a rhododendron to plant whenever the fancy took you, even if you had the money.

So only houses of those really well-off, well connected, those unscrupulous and those extremely dedicated looked somewhat-fancy at least some of the time.

However as a child I did not know anything else, so I thought this is how it is supposed to be. This is normal. It was only much later, shortly after the Iron Curtain fell, when I had an opportunity to cross the border to Germany and visit the town where I now work. The contrast was incredible. Every garden neatly kept, mostly with at least some decorative shrubbery and a patch of flowers. Facades also well maintained, brightly painted, with whites white, greens green and reds red. Even the macadam streets looked cleaner and it is hard for a road to look clean.

The Iron curtain has really managed only to make the whole country look poor and rather mediocre at its best. The black and white photographs are sometimes actualy an improvement over the real thing.

Sunny Spider

As I was walking around the sunflower yesterday evening, making some pictures before the sun sets, I noticed a strangely positioned bee. When I looked closer, I realized that it is strangely positioned because it is dead and being held by a bright yellow crab spider. You can see it in the yesterday picture, if you look close enough.

So of course I had to go for a macro lens (the one I have built) and make a few close-up pictures. I tried my hand even at filming the fellow and it did not turn out all that bad considering that I do not have monopod (but I should buy one).

I have no idea what those little flies are doing there. Maybe they are insect equivalents of vultures? That spider must be strong and have quick venom to subdue a bee twice its size quick enough to keep a hold on it.

Lunar Eclipse 2018

These are my pictures of the event. Unfortunately half the time I did not know what I was doing, half the time I knew that what I am doing is wrong, and half the time I could not even see what I am doing. That gives you one and half of a clueless dork. It was exciting nevertheless and I am happy I could see such a thing. I wanted to witness lunar eclipse ever since I was reading about them in books as a little boy.

I think a few pictures are worth sharing. Here is the first one, taken just after the sky finally cleared and I found the dim moon in the sky. Rest is bellow the fold. The pictures are in chronological order, also the last ones show the Moon emerging from the Earth’s shadow.

A Sunflower Constelation

Nobody told our sunflower it is supposed to follow the sun with its main flower, and then stop facing east. It did not follow the sun at all and chose to face its main flower north the whole time instead.

And now it has developed a whole head of little suns facing in all possible directions.

There will be some pictures of its inhabitants in due course. That is, if I do not forget. There is a very interesting inhabitant in this picture too.

Youtube Video: I Smoke Armour

Metatron is not my favourite YouTuber, for some reason he rubs me the wrong way and on occasion he made me cringe when he opened his mouth about feminism (but to be clear, there was no obvious malice there, just cluelessness). But some of his videos are relatively good and I consider this to be one of them. Partly because my sister in law and her family are all heavy smokers who nevertheless looked at me in the past with derision for “wasting” money on books and time on bonsai trees.

Forest Path Statues – Part 2 – Owls

I can attest to an owl being a very good bird to carve out of wood – you need not remove as much material from the stock to get a good likeness and you do not need extra material for beaks and long legs and such like.

There were four statutes with owl theme along the path, and they were all cuteness distilled, especially the one with two of them cuddling atop a tower.
