Low frequency sounds are more difficult to localize than high frequency sounds, for a variety of reasons. I would be surprised, though, if a widely-spread grid of detectors wouldn't be able to find it. https://en.wikipedi

Image kernels generalize very naturally to real values (so naturally that it hardly constitutes a generalization). CAs can be generalized but it seems less natural. The common element you are picking up on, I think, is [comonadic computati

I am sympathetic to the aims here. I think it makes a lot of sense to represent the relation (a,b,c) where a^b = c in a unified way. Of course, it may also make sense to represent other ternary relations in similar ways, too. You could p
