    See figure 3 here: https://en.m.wikipedia.org/wiki/Thermodynamic_temperature

    As mentioned above, there are other ways molecules can jiggle besides the three translational degrees of freedom that imbue substances with their kinetic temperature. As can be seen in the animation at right, molecules are complex objects; they are a population of atoms and thermal agitation can strain their internal chemical bonds in three different ways: via rotation, bond length, and bond angle movements; these are all types of internal degrees of freedom.

    tl;dr Water be jiggly. Amount of jiggle is hard to put a number on














  • Cheers! I appreciate the small insight into the names that are common to people with some knowledge about these different types.

    So far, I might have a chance to name Dohle, Nebekrähe correctly and maybe have a good chance of picking Rabe, rather than Krähe due to its size, and being somewhat right about that.

    I’m always thankful if someone can tell me right away what things are called.


  • Haha Clichées sind dafür da erfüllt zu werden.

    Yeah as a kid i thought raven were much bigger and had orange beaks. Rather late I learned that ravens are usually just large crows. Personally, I don’t care much but at least try to learn and use the proper names of things. At least in German, using Krähe seems to be a safe bet in any case.

    Nah it’s alright, the RF series is rather niche still and when it’s much more reasonable (price per quality) I might as well use an EF with the adapter. As my always-on lens is the RF 24-240mm (very useful for travel when you don’t know what you’ll do that day), the size&weight of EF 1.4 + adapter would still be quite a bit less.
    Apparently, I can rent it via a service for 20 or so bucks a month. That’s fair.

    grab my […] for its size and weight and wish I had brought my […] instead.

    Story of my (photo-) life haha. It’s so hard not to feel sad when you find a situation where a certain piece of equipment you left at home would’ve been sooo much better suited for the task. But you just can’t carry all lenses, a tri-pod and a flash with you everytime you leave the house. Even taking the camera is hard enough sometimes…
    Thanks for the suggestion of renting it. Might give that a shot. There might even be a service for it I’ve used before. I wouldn’t like to pretend-buy something just to test it, though I’d probably keep it after what you’ve told me.
    Sadly, there’s not 1.4 RF lens so I would have to use the EF-adapter as well. But considering the weight and size that should still be quite acceptable. Not sure if there’s a trade-off regarding image quality when using the adapter but probably not enough for me to notice anyway.
