Time variation of a fundamental dimensionless constant
Authors: Robert J. Scherrer

Abstract: We examine the time variation of a previously-uninvestigated fundamental dimensionless constant. Constraints are placed on this time variation using historical measurements. A model is presented for the time variation, and it is shown to lead to an accelerated expansion for the universe. Directions for future research are discussed.

Yes, it did:

More speculatively, one might consider the possibility that the values of the integers could vary with time, a result suggested by several early Fortran simulations.  This possibility would have obvious implications for finance and accounting.

Also, don't miss the caption to Figure 1.

IV. THE OKLO REACTOR
No discussion of the time-variation of fundamental constants would be complete without a mention of the Oklo natural fission reactor.

Acknowledgments
A number of colleagues were kind enough to comment
on the manuscript. For some reason they did not want
me to use their names, so I will identify them by their
initials: S. Dodelson, A.L. Melott, D.N. Spergel, and T.
J. Weiler.


That's a pretty subtle april fools. :) Not exactly supergluing the teacher to her chair. :p

He needs to look into whether the lifelines of the integers can cross--i.e., will 6 ever be larger than 22? What will this mean for sports records?

They forgot to mention that Pi=3 had popular support for some time from a well known book (Second Book of Chronicles, chapter 4, verses 2 and 5). In 1897, Representative T.I. Record of Posen County, Indiana introduced a bill defining Pi=3.3, 3.23, or 4. Highly variable indeed.

April fools notwithstanding, here's an interesting brain fart:

With pi defined as the ratio between the circumference and diameter of a circle, it's value is 3.1416... only in an Euclidian geometry.  If space-time has a positive curvature (closed universe), then is not pi < 3.1416... (and > in negative curved space) so in principle could we measure the local curvature by a careful measurement of said ratio?
And does that not imply that pi was much smaller shortly after the Big One?

I'll get me coat...

Sometimes pi is larger before dinner than it is after dinner.

Code Sample
call ChangeSportRecord(6)
end
subroutine ChangeSportRecord(i)
 integer i
 i=23
 return
end


That'll do it.  At least in Fortan IV

Of course, our model gives the
opposite sign for the time-variation of ?, but this is a
minor glitch which is probably easy to fix.


Was this just an innocent April Fools, or was it specifically a parody of the IDCs?  Seeing the graph of the historical measurements of pi, I couldn't help but think of the crap Sal Cordova (used to?) post about the historical measurements of c to "show" that c was slowing so therefore Earth is YOUNG!!1!Eleventy!

Aside from creationists like Barry Shetfield, there are a few real physicists that thought that the absolute value of c might have changed. They have been shown wrong.
