I found a math tipped over in the forest
an upside-down orange mushroom with branching coming from the center out radially in tuning-fork-like patterns with dark background.

For those of you that aren't sure whether it is a greater yellowlegs or lesser yellowlegs, just remember the greater yellowlegs eats the frog. I have included a diagram with and without annotation. I belief the latex is \gyl, \lyl #birds #math #greaterthan #inequalities #frog #mathInTheWild
A greater yellowlegs stands with yellowlegs to the left with a frog in its mouth. A lesser yellowlegs stands with yellowlegs to the right without a frog in its mouth. both create angles with the reflections of their bodies and face away from each other.A greater yellowlegs stands with yellowlegs to the left with a frog in its mouth. A lesser yellowlegs stands with yellowlegs to the right without a frog in its mouth. both create angles with the reflections of their bodies and face away from each other. There are annotations in white making the two math symbols and labeling "greater", "lesser", and "frog" in cursive.

I apologize for my alt text not being emotion free - I can't help it.
Two bushtits sitting shoulder to shoulder cuddling on a branch facing away from the camera with the most adorable fluff and little tails. They are grey with a little brown on their tiny little wings, and the cuddle is so cute I could die. The branch they sit upon is curved and they face an grape leaf, but fig leaves are blurred in the background with a vignette.

It turns out Weezer’s Sweater Song was about computation.
FIG. 4. (a) Diagram of knitted half-adder realized in our experiment. It adds two input bits, A and B, to produce sum bit, S
and carry bit, C. The logic gates of NOT, AND, and OR are highlighted in green, blue, and red, respectively. (b) The circuit
diagram of the half-adder illustrated in (a). (c) Experimental realization of the half-adder. The tags of the input and output
bits are attatched to the yarn loop for a visibility. The tags correspond to the input and output logic values are released from
the computer. (d) The half-adders after the computations for all four inputs, A= 0 and B = 0, A= 0 and B = 1, A= 1 and
B= 0, and A= 1 and B= 1. All outputs are confirmed to be correct.
