This is a joke more or less, maybe less, but it speaks to a rhythm in “nature” all aspects thereof, that is pretty fun to see. One of my colleagues/friends/fellow emeriti (though he would choke if i used that terminology for the two of us since he has achieved mountains more that I did-or at least I am led to believe that) sent a graph of the Milankovitch cycles (the debate is global warming). I looked at the blue plot on that graph he sent and just laughed out loud…. Here in this image i am plotting what I am working on currently, and see how fun the two look beside each other. I am not assigning any purpose to this post, just laughing.
