But the early universe was very hot, very dense, and gravitationally very different from the comfortable-to-us 1 g we experience today on the surface of the earth. Einstein has convincingly shown that spacetime is accordingly divorced from that human experience. Clocks, for example, are affected by gravity and satnav constellations have to take this into account. Did the first three minutes flow the same way three minutes flow in the here and now? I sent that question to Chris Impey’s online office hour and he kindly answered. It is a tantalizing response and one that will require substantial further study to fully appreciate – perhaps finally diving into the guts of GR. It makes me wonder even more intensely why we anthropomorphize those intervals the way we do.
COVID ravages the world. America bails out Boeing, Wall Street, and if all goes to plan, assorted chunks of 45’s cancerous financial empire. Meanwhile, Germany rolls out support to its artists and musicians, a nod to what that nation holds dear and what it finds worth defending.
In honor of a plague-affected World Piano Day, the German record label Deutsche Grammophon virtually brings together a number of celebrated pianists to help us remember that our mostly corrupt, degraded, and base species nevertheless has had moments of glory.
The CDC and WHO are giving us good advice on what do in this Plague Year. The Research Collaboratory for Structural Bioinformatics (RCSB) is showing us the molecule causing the havoc. Check out the structures of the various flavors of Coronavirus at The Protein Database (PDB). Click on the images, most of which will go to detailed pages including 3D models that can be spun in the browser. Knowledge will be power in dealing with this beast and let’s offer thanks to the research groups who took the lead in characterizing it which must have come at considerable risk to themselves. When it mutates, and it will, they and others will undoubtedly don their capes and do the measurements again.
It is damnably, horrifyingly beautiful in David Goodsell’s artistic rendering of it infecting a lung:
“Be it ever so crumbly, there’s no place like Rome” said Bugs Bunny and was he ever correct. In the face of a real problem, our farcical economy is exposed once again as a house of straw and sticks on quicksand with vultures above and weasels beneath. And I apologize to vultures and weasels everywhere.
