interesting discussion of number systems
including comments on
numbers with dimensional labels on
FaceBook : FORTH PROGRAMMING LANGUAGE
21st CENTURY
- A discussion , off topic , on the SiliconValley-ForthInterestGroup
mail list on the basic physics of planetary
temperature . Archived : Re: [svfig]
<NSF>MathCad and as eml .
Here's my last reply , Beyond that , start at http://cosy.com/#PlanetaryPhysics

I'm
talking about the ` climate models which
predict mean global temperature going out to the
end of the century used for political purposes .
Weather models are much more tied to reality .
The spectral GHG paradigm , aka:
box , claims the ~ 33c difference between the
inexcusably crude estimate of our planet's
radiative equilibrium and our ~ 288K is due to a
spectral ` GreenHouse effect . My Heartland talk
mainly works thru the handful of lines of K
, starting from the computation of the 5.e-6 of
the celestial sphere the disk of the Sun covers
, ( is that a model ? ) to show the quantitative
absurdity of claiming that Venus's bottom of
atmosphere temperature , about 400K above its
orbital gray body temperature of ~ 323 , about
2.25 time that orbital temperature , about 25
times the kinetic energy density , is due to
some spectral effect .
James Hansen et al's
1981 paper which is an embarrassment to
NASA , seems to have been instrumental in
coalescing the paradigm , attributing w/o
derivation or equation the gravitational
adiabatic ` lapse gradient ( the 33c )
to some sort of spectrum heat trapping rather
than the universal tradeoff of gravitational and
kinetic energy .
Both sides of the debate ,
including on the ` skeptics side Roy Spencer ,
Anthony Watts , Willis Eschenbach , have been `
trapped in this box , actively disparaging any
idea that gravity has to be considered . But ,
if you are writing energy balance equations ,
and believe in conservation of energy , of
course it does .
As I said , these AGW models are
pathetic . They go off into Navier-Stokes
finite models w/o ever deeply understanding the
most simple non-optional testable quantitative
classical physics . They are making claims
about the planet getting a percent or 2 hotter
in the next century -- well it used to be , now
its down to 80 years , when they literally don't
know how to calculate the temperature of a
billiard ball under a sunlamp .
Well , you asked ,

20200813.1015 | BAA Zoom One point which
came up is combinators and Iverson's ` forks
& ` hooks
and ` commute
, ⍨ , in APL which I attribute to John Scholes .
In Forth since it's just ' swap . In CoSy/AltStackOps.f
it is also aliased to ' --ba :

My understanding of combinators is shallow . But the
most generic is the Y combinator . I really means just a
verb which
acts on 2 arguments rather than just 1 , but in
either case , returning just 1 result .
In APL terms , dyadic
as opposed to monadic
.
CoSy
largely sticks to the discipline of not having more
than 2 arguments .
