pandemic year 2

If only folks could get that masks are the antidote and not the cause for shutdowns. Moreover, of course, that our collective opponent is a virus and not a subculture.

honorable traditions

 In the language of the wild west, and in the spirit of those ancient highway "Burma-Shave" signs:

• It's bad manners to bring
• a knife to a slugfest, or
• a pistol to a blade brawl.
• Thus healthy traditions die
• when guns are held by all.

binarize less unify more

 In the world of big ideas (not math or binary logic) the opposite of stupid is also stupid. Binarizng descriptions of social events (does/doesn't cause illness as opposed to a probability, cartoonification with party rather than individual identifications) can mitigate electronic media's tendency to polarize.

model selection math

This is an area of key integrative importance in this age of electronic ideastreams.

technical definition

Proper acceleration is the physical acceleration experienced by an object relative to a locally co-moving free-float frame. This may be quite different than the coordinate-acceleration seen in a separate reference frame (inertial or not) of co-moving yardsticks and synchronized clocks.

The proper-acceleration 3-vector, combined with a null time-component, yields the object's four-acceleration (as measured by the object itself) which makes proper-acceleration's magnitude Lorentz-invariant. Thus proper-acceleration comes in handy: (i) with accelerated coordinate systems, (ii) at relativistic speeds, and (iii) in curved spacetime.

Proper-acceleration reduces to coordinate-acceleration in an inertial coordinate system in flat spacetime (i.e. in the absence of gravity), provided the magnitude of the object's proper-velocity (momentum per unit mass) is much less than the speed of light c. Here we focus on situations where proper-acceleration and coordinate-acceleration are not always the same.

Opening post

"One-new-fact" topics that we are interested in for discussion here might include e.g. traveler point dynamics (TPD), task layer multiplicity (TLM), moon baseball, single-slice electron optics (SSEO), dimensionless units rad/deg & mole, coldness in GB/nJ, concept-selection, organism-centricity, correlation-based complexity, carbon rain (in cool star atmospheres & the lab), and total-sound videography (TSV). 

For instance, a "new fact" for our TPD project may be that metric-first relativity opens the door to curved spacetime & accelerated frames in everyday life, for our TLM project it might be that activity time looking in/out from skin, family & culture can quantify community-level health, for our SSEO project might be that single-slice electron optics can give everyone a view of the nanoworld through "electron eyes", and for TSV that our real-time sheet music app offers up a visual guide to any sound that you encounter. N'est-ce pas?
