Mini-journal:  

March 25 2023

Saturday mornings.  Toasted onion bagels and 
Roy Rogers movies.  I tune in for the songs 
and the light-hearted scripts.

Thankful for the soothing sound of my furnace 
and for the sound of Lucky's gentle snoring.



I've had a website up since getting on the Internet in 1996, but 
it was tiny until I started adding more of my activities in 2017.
Things add up fast in spite of trying to minimize it.

 * The Proof *

 Andrew Wiles tackles the 350 year old mystery
 of X^n + Y^n <> Z^n in an eight year odyssey,
 working in isolation.  This is the best story 
 of personal drama and enchantment I've ever
 watched.  A lovable cast of characters 
 (Wiles and his math colleagues).



 * The Flight of the Snow Geese - 1972 *

 Des and Jen Bartlett care for orphaned 
 snow goslings from Hudson Bay to Texas.

 Emmy for cinematography.

Current project (December 2022):

I've long yearned to have a kitchen like the
one in the photo on the right. I have a room
in my basement which has a full-sized east-
facing garden-level window; and I'm going to
build a precise replica of this kitchen in
that room, arranged and sized to fit that
room's shape and window placement.  
I already have a retro oven and retro frig in
the basement, to which I'll apply a white
enamel finish.  I also have a retro table of
the same size as the one in the photo, whose
formica top I'll change to red with full-gloss
polyurethane enamel.

I just finished modeling it in RogCAD

No time for a western trip in 2020.

Not posting photos from the 2021 western trip, because 
Bart died during that trip from a lung infection.

Relativity in absolute terms

There are only three sane sections in the Wikipedia article 
on the twin paradox.  I authored those sections in 2011, 
and they've been there continuously since that time:

Here's the link to the three sections below.

   4.  A non space-time approach
   5.  The equivalence of biological aging and clock time-keeping
   12. No twin paradox in an absolute frame of reference



link:  The originality and uniqueness of Relativity Trail



The twin paradox of special relativity cannot be resolved without 
acknowledging a hierarchy of clock rates dependent on a hierarchy 
of inertial motion.  © 2022 relativitytrail.com

Relativity Trail explains the time differential between reunited clocks, 
eliminates the twin paradox, diagrams Einstein's clock sychronization 
in absolute terms, and ends all confusion regarding relative frames of 
reference.  It's completely compatible with, and in fact subsumes, 
Einstein's relativity.  It reveals what is transpiring behind the scenes 
of Einstein's treatment.

Spacetime is shown to be dependent on Einstein's clock synchronization 
method, and is properly relegated to a geometrical construct which 
comes up short as a physical reality.  © 2008 relativitytrail.com

Relativity Trail, with 192 pages, 65 diagrams and 75 illustrations, 
will provide you with complete detailed algebraic derivations of all the 
kinematical effects of special relativity.  Everything is charted out in 
absolute terms against a system at rest with respect to the totality of 
the universe for perfect clarity as well as soundness of theoretical basis.  
It is the totality of the universe that imparts the inertial properties of 
clock rates and lengths which generate the effects of relativity.  
This is explained in detail in Relativity Trail



Introductory document:

Relativity in absolute terms (Twin Paradox in Relativity)
(can be read with comprehension in twelve minutes)

Absolute versions of Einstein's postulates 
(a snippet from the above document -- can be read with comprehension in three minutes)

Twin Paradox Animation on youtube.
Light rays and traveling twins are charted in absolute terms, 
free of the misleading space-time diagram.
I wrote the program code for the animation using QuickBASIC for DOS.
