  • Density comes into it if we are measuring buoyancy. The weight of the displaced water is equal to the weight of the buoyant object, and the ratio of volume submerged vs above water should give a way to determine density, but I don’t have the precise method in my head right now.

    However assuming all you want is the volume, you simply need to fully submerge the object (by applying enough downward force if its density is too low), and the displaced volume is equal to the objects volume. The displaced water will have to flow to the top of the container, so by measuring the rise in water level and multiplying with the base area of your container you can get it easily.

    Just make sure you don’t accidentally also measure your hand if you’re pushing down the sphere.


  • A0 is a square meter. Its sides are self similar, such that the ratio of long to short edge stays the same when you cut one in the middle, and thus create a new long and short edge.

    Each cut produces two sheets of the next Ax number, so A4 is four times halved compared to A0, or a sixteenth of a square meter.

    That property of being able to halve is achieved with a ratio of the square root of 2, so unfortunately the measurements in absolute numbers get pretty odd.



  • I assumed the blonde girl was were when the teacher came home, but then the meal prep confused me for a moment.

    I thought that implied she was making meals for a were during the monthly change. But it seems she was making human meals for when she herself was changed and would be unable to cook.
