      Gaat er iemand? Heb zojuist mijn VIP ticket besteld ^_^

      Ik was er vorig jaar ook, voor het eerst, het was echt top.

      I remember watching the recording of the panel where they announced Monty was joining Rooster Teeth.

      I've seen Haloid once before, so the link was made in my head. "Awesome, now they get some more freedom with CGI," I thought, as a fan of RvB. But then, he exceeded my and everyone's expectations. Not settling with awkward programmed CG, no, going full motion with motion capture. While working hard as he could to survive, as he wrote in his [beautiful blog post, Passing, you could also notice the young boy playing, enjoying himself, and efficiently making us enjoy what he does.

      Always looking for new challenges, always coming up with new ideas, to have fun, to work on, to push his limit, to test his efficiency. While creating and designing RWBY, always thinking of the fans, creating costumes easy to cosplay as, always with enough pockets so it won't be impractical to walk around with on conventions. His mind everywhere, even when sleep deprived, sharp enough to counter lemons or do some slick dance moves. Always eager to learn more, not satisfied with just a single input. No, he needed nine monitors with different movies, anime series, documentaries etc. playing on them, to make full use of his time and not holding up anyone else.

      And still he's got time for people.
      He made relationships happen, and even managed to find time to find someone to call his.

      I'm sad a lot of people and I haven't had the chance to actually meet him, to let him know what an inspiration he was. But I'm also glad he was there, made the fullest out of his life and did what he did. Though he may not physically be here with us anymore, everything he was to the world, he still is.

      DISCLAIMER: I like the podcast crew is talking about stuff and science and find it very entertaining, whether they're wrong or right. But in the tweet stream I sometimes encounter people not entirely aware of the science behind some things, so I'd like to try to clarify some things, so everyone will have some interesting facts to share at parties.
      I only possess a bachelor degree in chemistry, with personal interests in physics, math, astronomy, history, anthropology, linguistics and more. I can't guarantee that 100% of what I say is correct (to err is human), but I will try to add in references and sources where I can.
      Feel free to correct me.


      RTPodcast #222 - Water: temperature and pressure.

      First of all, "thermos" is indeed a brand name, but in quite a few languages the object is referred to "thermos flask" . It is also known as a vacuum flask.

      It is called thermos, because of the thermostatic properties of the flask. Heat can be transferred in three ways: conduction (i.e. an electric stove), radiation (i.e. a heat lamp) and convection (ironically, main method of a radiator).

      A thermos consists of a container within a container. Between these two layers, there is a vacuum. A vacuum is a very bad heat conductor, due to the fact there is nothing to conduct the heat with (and no air/liquid to convect it with). It thermally isolates the inner container. There is still a very small heat transfer by radiation and you'll enable heat transfer with the surroundings when opening the flask.

      So heat has a hard time leaving or entering the flask (technically the cold is the absence of heat).

      STP: Standard Temperature and Pressure
      - 293 K / 20 °C / 68 °F
      - 1 atm / 101325 Pa / 14.6959 psi

      Gavin: "So I have a thermos/cylinder that holds water. Above that, I have a pipe with a flat circle on it that's the exact width of the thermos. I'm pushing down and it goes into the thermos, it is sealed. Can I then crush the water to be more compact than water is? Say air can get out."
      Gus: "Air can get out but water can't? Is that possible?"

      It is possible to let air out but keep the water in by using special membranes. But with Gavin's description with an off-the-shelf thermos, it won't be possible as the air can't escape, unless the circle doesn't have a perfect seal, but then water will get out too.
      But what will happen?

      As most of us know, water has three phases: ice (solid), water (liquid) and vapor (gas). At standard pressure, water freezes into ice at 273 K and boils into vapor at 373 K. But what if we keep the temperature constant at standard room temperature and vary the pressure? As will be explained in the next part of this post, we can expect the water to boil at lower pressures. But higher pressures, is a more complicated story, because ice can take on multiple forms. We'll have to take a look at the phase diagram of water. On the x-axis the temperature is given, y-axis pressure (logarithmic scale). As you can see, there are several categories of ice. First water will be compressed and a bit more densely packed, but not by much since liquid water is already almost as dense as it can be (maximum density of liquid water is at 277 K at standard pressure). But when it hits the transition to solid, it becomes a bit more extensive.

      I will try to shortly explain what causes the different types of ice. As you know, water molecules are H2O. The very special property of this molecule is the angle between the H-atoms, 109°. Another special properties is the ability to form hydrogen bonds, also depicted in the image. Oxygen likes to pull more electrons towards it when it's bonded to something else and is electronegative. This causes the hydrogen to be slightly electropositive. This enables water to form hydrogen bonds, pretty strong intermolecular bonds.
      "Normal" ice we all know is called **Ice Ih** (ice one h), with a hexagonal crystal structure. As you can see in the image, there is a lot of dead space, which explains the lower density of normal ice opposed to water, which kinda looks like this.

      But other crystal structures can be formed. As you can see in the phase diagram, if you increase the pressure at standard temperature, at about 1 GPa ( Pa, equivalent to the pressure of a tower of 21.000 elephants on your desk) we hit Ice VI (ice six). It will form a tetragonal structure (triangle base pyramid), which is more dense than Ice Ih. Increase the pressure even more, and you'll form Ice VII, Ice X and Ice XI, all with different structures. For more information about it, visit www.lsbu.ac.uk/water/ice.html

      In short to answer Gavin, you'll form slightly denser water and then more dense forms of ice.

      I got some people Twittering to me that ice will melt under pressure, as that is how ice skating works. While it is a very plausible explanation for the mechanics of ice skating, it hasn't been fully confirmed.
      The idea behind this is because of the pressure, heat is released and melts some of the ice, creating a slick liquid layer. It is true that because of pressure, heat is released from one piece of ice, that melts another piece of ice. But the scale of temperatures, pressures and size involved in this is not really applicable in the described scenario.

      TL;DNR: Water is hardly compressed, at very high pressures will become dense forms of ice.

      Continued in next post.

      Does anyone else experience motion sickness with certain games?

      I get motion sick from some games, diminishing my enjoyment. The games I notice it the most with are the Elder Scroll games, any Valve game (TF2, Half Life, Portal) and the 3D Metroid games (I've never really understood the hype around Skyrim, maybe because of this). It seems games with motions that are too smooth (no motion blur) cause this.
      Sometimes Minecraft also makes me feel unwell, so on bad days I need to pause the Let's Plays for a few minutes before continuing.

      I do have a small remedy though, wristbands that help against sea sickness, that work by pressing onto pressure points in your wrist. But they're not very comfortable, so I don't like to put them on every time I whip out a game.

      Has anyone found an efficient way to manage the downloaded map variants and stuff?
      I've been downloading the Horse maps and trying to rename them so I can recognize them, but it takes a lot of time to do that. I plugged a keyboard into my XBox360 to speed up the typing, but are there faster ways?

      Does anyone get motion sickness from playing games (notably FPS's)?
      I do, except for Halo, that works fine for me.
