Nick on ‘brick: Another look at 2001

/tap /tap

Is this thing still on?

Apparently.

I’ve posted previously of CinemaTyler’s excellent but breathless exploration of 2001: A Space OdysseyParallaxNick takes a more leisurely and historical look at the same film. It is less about the filmmaking process and more on its origins, development, context, and implications.  Nick’s videos about astronomy are well worth the watch.

The time is out of joint: Chris Impey on the tick-tick-tock of the stately clock

Steven Weinberg wrote a famous book, “The First Three Minutes” on the early stages of the universe.  The same universe became transparent to light some 370,000 years later.  There are other landmarks in post-Big Bang time going down to bewildering fractions of a second.

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.

World Piano Day: Deutsche Grammophon’s virtual festival

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.

Artists include Maria João Pires 0:00 Víkingur Ólafsson 21:15 Joep Beving 40:38 Rudolf Buchbinder 01:05:39 Seong-Jin Cho 01:25:24 Jan Lisiecki 01:44:02 Kit Armstrong 02:14:19 Simon Ghraichy 02:46:18 Evgeny Kissin 03:17:43 Daniil Trifonov 03:26:00.

Update 3/31/20: Well, so much for DG’s benevolence.  The video has been marked Private.

 

COVID’s Metamorphoses: RCSB Coronavirus resources

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:

Market plunges: Winthorpe and Valentine held for questioning

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.
