This blog contains art by me - Jan Pospíšil and all kinds of other things I find interesting and worth writing about.
Here's my portfolio:

What sorcery is this?! A post with art? In colour? Your eyes do not decieve you. I have indeed picked up the virtual brush and put more than just black and white on my virtual palette.
This painting is a cover for a book called "The Singing Sword - Tea Dragon and Cat Demon". (written by Zbyněk Holub)
It's
a fantasy novel about tea faeries. I don't know much more than that.
Tea is important and so are the dragon and the panther - they're
characters in the book and good friends.
(ArtRage as always)
(only now I realized I painted the foliage a bit like the leaves of green tea I've been drinking lately. Well, it fits. :))
Which singing sword do you like better? The one in the knightly Bugs Bunny episode? Or maybe Lilarcor in Baldur's Gate? :)
(this one will be long, I apologize for that. It's been long coming.)
This post was originally supposed to be about proper ways to sit in front of a computer, about specific exercises you can do to stretch and strenghten your back. That was when I thought I had simple back problems. (most likely I will do such a post in the future)
Last spring I started noticing small health problems. My hearing and sight were getting worse, my skin would tingle and itch or burn in places, sometimes my fingers went numb. Small muscle spasms were getting quite frequent.
And my back would hurt in one spot, not a huge annoyance, but sitting was getting a bit difficult.
So I went to see the doctor - an orthopedist, because I thought I might have had a herniated spine disc.
He didn't think so, because I could bend over easily and except for those neurological symptoms, I felt quite alright.
He did suggest I had blood drawn and tested for Lyme disease.
Knowing only very vaguely what Lyme disease was I agreed and had my blood tested in a couple of weeks, since I had a lot of work and exams to study for.
Somehow, studying was quite difficult this time. I could not concentrate, I'd have to read a slide three times and I'd still forget the contents a few seconds after. I felt like my days went by in a haze, I was constantly tired, I was waking up tired already. I couldn't understand what people say, what the words mean. Reading was difficult and annoying, even seeing, recognizing faces I had to focus on fully.
I attributed this to fatigue, exam stress.
Then, suddenly, I got the test results on the phone - the Lyme test was positive.
I've read up on Lyme a bit. It's a disease caused by bacteriae with a rather extensive list of possible symptoms.
I remembered that I may have had a red patch like the erythrema migrans, which I thought was a large mosquito bite. I wasn't sure when/if I had that though. I also remembered a strange flu-like thing I had last winter, with cold/hot shivers, but which only lasted three days and from which I recovered surprisingly quickly.
The doctor assured me this was treatable with antibiotics, that'd I'd be just fine in three weeks.
Then doubt kicked in.
1) My normal doctor continued sending me to specialists for all kinds of checks and tests, but he wouldn't treat me despite having two positive Borelia tests. (his reason - it's summer and you'd get sunburns from the antibiotics)
2) I read on Lyme some more.
Turns out that most doctors in most countries will tell you this:
"Lyme is easy to treat, especially if we catch it early. 3 weeks of antibiotics and you'll be fine."
Except there are people who don't get fine. And they're hardly a minority. In the few months I've known about being sick, I ran into quite a few people who either had the disease in the past and problems persisted, or contracted it recently and recieved the same 3 week treatment.
I trust doctors. They're trained to do their job. There's science behind what they do.
But.
For strange reasons I can't quite understand, this whole Lyme disease issue is hugely politicized. I won't try to convince you of a global conspiracy against Lyme patients.
One does really sound like a nutter talking about this weird disease he has. He seems fine on the outside, he must be crazy. Even my friends think so, a bit. Maybe my family too.
A very common treatment of chronic Lyme are antidepressives and psychiatric therapy. Does it work? (you can guess)
Why am I writing this? What do I want from you?
Because it took one tiny tick and my life changed considerably. If I didn't research myself, if I didn't trust my logic more than my doctor's training, I might've ended up considerably worse. Because I don't want you to end up like me.
Please, read up on the symptoms. Remember them. Also remember these important things about Lyme:
1.) It's treatable the best in the early stage. If you find a suspicious bullseye after being bitten by a tick, go to your doctor. Show him the ILADS guidelines, get tested AND treated with high doses of antibiotics immediately after having blood drawn, for at least 4 weeks. Insist on getting treated!
2.) The current tests for Lyme are RUBBISH! The probability of a false positive/negative is incredibly high, but the doctors WON'T TELL YOU. You can easily read up on this, all the info on these ELISA/WB tests is on the internet. Still get tested, but learn what the results mean, don't let the doctor tell you simply "it's positive/negative". Many doctors can't read these tests properly!
3.) Even in the later stage it's possibly treatable, but it's unclear if it's curable completely. You can get better though. The best chance is a combination of antibiotics/antimicrobics. It takes a LONG time.
4.) Testing negative for Lyme does not mean you don't have it. Doctors will tell you it does, but it's simple logic. What the test does - it looks for specific antibodies, which the body's immune system makes to battle the disease. Their logic is - if you don't have antibodies, there are no bacteria. Except Lyme attacks the immune system and often tests are done while you're on antibiotics, which also messes with the IS. There are people who have a proven Lyme infection, with living bacteria found in their bodies, who do not produce the antibodies and test negative. Lyme experts advise to diagnose Lyme from symptoms, not simply base the diagnosis on unreliable tests. Remember that. If you feel like shit, if you joints hurt and swell, if your head hurts constantly, if your heart beats really fast, if your vision is bad, if your skin crawls and tingles all over, if you start losing feeling in your fingers or toes...etc. etc. You still may have Lyme, even if you test negative.
5.) Antibiotics are your best bet. Read up on herbal treatment, read up on zapper machines. I think herbs may help, but I'd still take them together with antibiotics. Zappers I think are bullshit.
6.) Most importantly - DON'T TAKE LYME LIGHTLY! It's not quite the minor three week annoyance it's made out to be.
Also, watch this documentary. It's very emotional, it's quite subjective. But it should be. It's heartbreaking, but watch it still.
I've been tested positive for Lyme right before last summer. Since then I took the standard three week antibiotic treatment. And while that helped a bit, I still felt almost the same after. I didn't give up and found support in my family. I've been on a combination ATB treatment since then.
Yes, I've been taking antibiotics for more than two months.
And I feel SO MUCH BETTER!
Recently I've been really getting back to normal. Some problems still persist, I discovered a mild case of carpal tunnel syndrome in both my hands, but overall I got much much better.
I still have some time to go on the treatment we planned. We'll see if it returns after I go off the meds. Maybe I'll continue with something else.
Please, don't think me crazy. I simply did what I thought was logical, what made sense. Not what I was told to do.
If you've read past here, I can't believe you did, wow. :D Thank you so much.
If I got the warning across, that's awesome.
Next time it'll be either swords, armour, or some art, I promise. :)
Dračí Doupě Lite will be released soon and we're calling it "the Pirate version". Therefore I had to paint a few pirate/ship/river related illustrations. All rather quickly. It was fun though!
Dračí Doupě 2 ("dragon's lair", no relation to the cartoony PC games of old) is finally done and will be properly christened with champaigne (ok, Bohemia sekt is more likely :D) on Saturday.
Here's a full lineup of art I've done for the book. I'm told the first books arrived from the printers and that they look amazing. You may notice (if you follow me that closely, I should probably consider a restraining order!) I revisited some of the older pieces.
Alchemist - a creator of artificial beings, explosives and miraculous potions.
Fighter - a breaker of bones, a crusher of livers, a jolly good chap all in all.
Wizard - a master of flames and winds, tamer of salamanders.
Druid - a friend to nature, shaper of plants, water and earth.
Ranger - a hunter of monsters, maker of traps, protector of men.
Hrun the Barbarian - wounded and grumpy.
Tumbler - a master of disguise, trickery, juggling and good judge of character.
An art post?! What?! Yes. I know, it's a surprise. I still paint though.
These three pieces I did for the Aztec Empire book by Paradigm Concepts. (which has been released at Origins) They were painted a bit faster than I'm used to and through a few sleepless nights. Normally they'd be better planned, but I kinda like the spontaneous feel, where I just didn't have time to fiddle.
Also I finally got to paint a character wearing a human skin-suit. \o/
Because my sword related posts seem to be more popular than the rest of my rambling, here's a new one! ;)
Especially popular was my list of sword mistakes artists quite often make, so this is a bit of a sequel to that. Today we'll be talking about one general art issue and two specific fun bits from my favourite movies.
1) Cracked and chipped blades
Ryan A. Span suggested this and I thank him for that - it's a good one. While I couldn't find a good representative example of this issue right now, I'm sure you've all seen this a lot. Maybe you've even drawn this way? I know I used to. ;P
Nicks and cracks are painted or drawn on sword blades to make them look used, as real objects. To make the blades seem less boring and artificial.
I would suggest learning more about how real swords change with use in the hands of a person who cares about his tools, how they're sharpened and polished. (and what else you can do to your drawing of a sword to make the boring parts more interesting)
Nicks will happen even if you're careful, but one usually tries to grind them out if they're small enough. Cracks are not good, you do not use a cracked sword. Scratches happen too and while you could polish them out, they don't really hurt the blade much.
Any reenactor, or a sword enthusiast will tell you one thing - if a sword blade has a crack in it, or a large chunk chipped off, YOU SHOULD NOT USE IT. It is most likely going to break and even if the blade bits don't hurt you while flying off, you'll end up with a broken (useless) sword.
(sorry, Blogger won't let me embedd this as a video.)
It's a well known scene - Conan's father makes a sword while Conan and his mother watch. First he casts the iron in a mould cut in a stone block. Then he beats it on an anvil and reheats it a couple of times. (Mysteriously, the engraving on the blade appears before one of these reheats, but we'll not talk about that.)
Can you in fact cast an iron sword? The answer is complicated, as always with swords.
Yes, you could do it, but it wouldn't be a good sword, if you could use it at all.
Now we see the blade is getting some treatment after the casting, so that would be ok, that would produce a sword like object indeed.
The funny bit is the casting itself.
If we agree that what was used in history was something that was proven possible and useful at the time, we should conclude that casting iron swords is unrealistic.
I'm told that casting certain parts of swords can be done - crosspieces and pommels for example. The problem with casting iron is the temperature. Iron's melting point ranges from 1200 to 1500 degrees Celsius, depending on the amount of other metals in the alloy.
("WAIT!", I hear you say, "iron is not an alloy!" Well, yes, but a swordmaker would not usually have a chunk of pure iron to work with, nor would he want to. We could call it steel, but that's another can of worms I'm not yet ready to open)
Achieving this kind of temperature for successful casting seems to be rather difficult (for the smiths of old, of course we do cast iron nowadays).
edit: As pointed out in the discussion - beside the temperature, other problems arise while casting iron swords. Iron swords tend to be longer and thinner - you'd need to achieve such casting technology that you'd avoid bubbles/porosity and other casting artifacts. You would also figure out a way to cast iron so that it doesn't pick up a lot of carbon.
Bronze for example melts at about 800 degrees Celsius, depending on the tin-to-copper ratio. (copper has a higher melting point than tin)
That is why bronze swords were indeed made by casting into clay moulds.
Smiths have always had a specific status in the society - very similar to shamans and mages. Alchemy itself arose from the practice of smithing. A smith, a metal worker is able to do transmutation - to change one substance into another. To speed up a process which was believed to happen over thousands of years in the vomb of mother Earth - the purification of metals. (the common belief from antiquity to medieval times was that metals grow in the ground - from low metals like lead into perfect metals like gold)
What else do you call someone who takes a pile of rocks, puts them in a fire, performs a lot of strange actions and transforms these rocks into a shiny sword? He's a magician.
Steel/iron swords are not usually made by casting. (I'm not aware of any instances of that, please correct me if I'm wrong in thinking this.)
Then again, it'd be kinda bogus if Conan's dad taught him the "Riddle of bronze", wouldn't it? ;P
3) 13th Warrior - The Scimitar Grinding
I love the 13th Warrior. It's one of my favourite movies ever. And I love this scene - it's funny, but it also shows Antonio Banderas' character getting some respect from his viking companions.
Sadly, as with the rest of the film, it's not very historically accurate.
A) He grinds the sword into something resembling a shamshir/scimitar - a curved sword we westerners associate with islamic warriors. BUT, by this time and a few hundred years later - Arabs were using straight swords - very similar to their western counterparts.
The dimensions of the sword were fantastical to begin with, real viking swords of this time were rather smallish.
B) Grinding is a useful technique which has been used in sword making and which is in fact prevalent in sword making today!
But considering the construction of viking swords of that time, grinding it down to this shape would mostly likely ruin the blade and make it near useless as a sword.
Pattern welding (often wrongly called Damascus steel) is a huge topic which could easily take a whole post to explain at least roughly, so here's a link that explains it rather well:
If you ground off the hard steel edges, you'd end up cutting with the twisted core. While I'm not sure what the exact result would be, it wouldn't be pretty I think.
That's it for today. If you have any questions, if you think I'm wrong and want me to know - the comments are right below. :)
How disappointing is it when a movie highlights its own plotpoints? How contraproductive when it shows how dumb a supposedly genius character is?
I've watched The Source Code and I'm sad to say I predicted my disappointment right from the trailers.
Now, I quite liked the idea of having 8 minutes to find something out in someone else's body. But bits here and there suggested the parallel worlds idea won't be convincing. And it isn't.
My main problem with the film lies in the character of the crutch-using scientist.
He constructed a device that supposedly allows a brain damaged person access to another dead person's brain and its 8 minutes of short term memory. Words like "quantum physics" were thrown around a lot, but what on earth does it have to do with that? What does this device actually do? There are two possibilities presented and I believe both of them are ridiculous:
a) It allows access to the memory of the deceased person. If so, the dreamer should not be able to do anything else than what the dead person did - from what we know of brains, any other action would be in fact dreaming - interpolation between bits of information stored in the memory.
A person familiar with door handles would know he can pull a door handle, but if the dead person didn't know what was behind a door, the dreamer wouldn't know it either.
Depending on the interpretation of this "science", the dreamer could see absolutely nothing, he could be prevented from opening the door, or he would make up something that would make sense to be in behind the door. But it wouldn't reflect the exact reality - the dead person's brain doesn't have the knowledge.
Now the movie itself acknowledges that this is not in fact what is happening. I ask - how dumb is the scientist who built this device then? His credibility as a character drops to zero the moment he implies it might have something to do with alternative universes, but still insists that it's simply a memory we can access. These two are exclusive.
Even if we accept this technology exists, it doesn't make a lick of sense.
b) It allows access to a parallel universe some time ago, it's real. If so, HOW?! I'm sorry, but saying "it's very complicated" doesn't cut it. I don't require techno babble and explanations for everything in movies, I'm perfectly fine with Inception's "yeah, we have this technology, it works".
But if you're going through the trouble of explaining the stuff with the brains, why not follow through with this too? The technology is constantly described as a brain link, a simulation - hence the idiotic name "Source Code" (which is dumb, because a source code is something you need to compile for the program to run, it's just a lame name picked to sound IT-ish)
The parallel universe aspect is completely missing and it's an incredibly stupid idea - if we establish the fact there are parallel universes, the universe where Jake Gylenhall saves the train ALREADY EXISTS SOMEWHERE!!! Him "going back" and "saving the girl" does exactly nothing. I'm no physicist, but if anything, he simply jumped from one universe in which he doesn't save the girl to another, where he does. Nothing is accomplished - congratulations! (except for him "getting that kiss" (oh Holywood) and LIVING ON, which also happens in an infinite number of universes beside the one we see in the movie) And he gets to stay in this poor guy's body after Jake dies? Wow, because we couldn't let the film end on a bit of a downer, right? How is Jake going to teach history anyway?
"Do you believe in fate?" Yeah. Screw science. It was fate.
I suppose we are to be astonished by the fact the army lady reads Jake's message, that it all happened. But if we're still going with the parallel universes hypothesis, ALL OF THAT ALREADY HAPPENED IN A PARALLEL UNIVERSE!
The army lady is not the same one we've been seeing through the movie, it doesn't matter that she thinks the device works - she still cannot change anything in her own universe. And all the changes she might want to make in the other universes have always been done in an infinite number of these universes. That's the bloody point of the multiverse theory. The ending scene changed nothing and is, as the whole film, pointless.
It's a mediocre film and I'm sure everyone with a basic knowledge of physics, brain biology and logic will see the gaping holes in its plot and characters. It doesn't deserve to be praised.
The actors weren't bad though.
