In memoriam of Tigger and more.

In memoriam of Tigger I offer the shown lily.
I didn't think the loss of Tigger affected Budda but he seems to have forgotten where the litter boxes are. If it's not one thing it's another.
Clear but real cold. I hope that doesn't portend anything.
I'm back to extra dimensions and Micho Kaku. It turns out that mathematician Georg Bernhard Riemann nearly beat Einstein with the mathematics Einstein needed to complete his theoretical work. I was again introduced to Riemann and the concept of metric tensors which are the basis of the math needed to specify various field values. Once again I get the concept but fail to understand the details. And again the question: Why did Einstein beat Riemann? How was Einstein's brain different than that if Riemann? Why him and not me?
Riemann's metric tensors are proof that we're all on this flight together.
