From the 7/20/2017 post "Divided Attention" —

Another phrase for *divided* attention is "bulk apperception."

Enveloping algebras also appeared later in the work on "crystal bases"

of Masaki Kashiwara. It seems highly unlikely that *his* work on enveloping

algebras, or indeed any part of his work on crystal bases, has any relation

to my own earlier notes.

Well, Romeo and Juliet, Samson and Delilah

Baby you can bet a love they couldn't deny

My words say split, but my words they lie

Cause when we kiss, ooh, fire

{Bridge}

Oh fire

Kisses like fire…

Burn me up with fire

I like what you're doin now, fire

Touchin' me, fire

Touchin' me, burnin me, fire

Take me home

A recreational problem from nearly two centuries ago has featured prominently in recent times in the mathematics of designs, codes, and signal processing. The number 15 that is central to the problem coincidentally features in areas of physics, especially in today's field of quantum information, as the number of basic operators of two quantum spins ("qubits"). This affords a 1:1 correspondence that we exploit to use the well-known Pauli spin or Lie-Clifford algebra of those fifteen operators to provide specific constructions as posed in the recreational problem. An algorithm is set up that, working with four basic objects, generates alternative solutions or designs. The choice of four base colors or four basic chords can thus lead to color diagrams or acoustic patterns that correspond to realizations of each design. The Fano Plane of finite projective geometry involving seven points and lines and Comments:16 pages, 10 figures Subjects:Quantum Physics (quant-ph) Cite as:arXiv:1905.06914 [quant-ph] (or arXiv:1905.06914v1 [quant-ph] for this version) Submission history
