    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

75byte #physics

u/tomxor

Perfect collision integration, since uniform gravity is constant it should cancel out in such a simple case, in which case integration can be skipped on a collision interval ?-b:b+.3 this is why it doesn't loose or gain significant hight on average
u/tomxor

To make it absolutely perfect this can also be changed to ?-b:b+.25 which will eliminate integration error since .25 is a non periodic binary fraction... it will bounce forever :)
u/tomxor

... but that would cost an extra byte so its no good !

Beenary Clock

u/tomxor

4 levels of geek - bees, beenary representation, beenary segmentation of 1 rotation of the hive into 2**16 (the lowest bee counts ~1.32s increments aka "bees"), based on the apiformes epoch (no leap bees, no queen zones, no hivelight saving bees, yes... it will gradually drift out of sync with the hive's rotation, currently by 20.48 bees or 27 "seconds" in old humanoid time. When the difference approaches 2**15 bees it is speculated honeygeddon will occur, or perhaps more realistically an aristocratic upheaval and abolishment of apiformes epoch based bee keeping).
