### Happy New Year

Lieven Le Bruyn has created a new blog, Moonshine Math (yes, the j-invariant!), born on Bloomsday as promised. Today also signals the coming of the new year, as Matariki rises in the sky. Maybe this year I'll get less spam telling me I don't need to be an average man any longer. Meanwhile, yesterday Mottle had an interesting post on a new paper by Dvali which considers a large number of copies of SM particle species as a route to explaining the heirarchy problem. Sounds a bit familiar.

Tommaso Dorigo posts about the D0 and CDF discovery of the $\Xi_{b}$ particle with a mass of $5.774 \pm 0.019$ GeV/$c^2$, which is about six times the proton mass. This particle is made of one down, one strange and one bottom quark.

The idea about very many copies of low mass copies of standard model particle spectrum sounds somehow familiar to me also(;-). More and more often I encounter things which sound like echoes;-).

By the way, the last issue of New Scientist contains an article about the discovery that only roughly one half of DNA expresses itself as aminoacid sequences.

A lot of introns, the "junk DNA" are transcribed to RNA. What this RNA might do? Topological quantum computation? As I have suggested for years ago. See the comments at my blog.

Kea, I am again advocating my old refrain.

The Dvali paper abstract contains "... maximum modulo N ..." and inequality mathematics.
Is this in the realm of mathematical game theory?

Compare the Farey sequence [0,1/2,1] to the reciprocal sequence [1,2,oo].
a - Limit theory shows that 0 and oo are reciprocals.
b - 0 is an additive constant in the usual antrhropic numbering system.
c - 1 is a multiplicative constant in the usual antrhropic numbering system.
d - 1/2 is 'half-way' between 0 and 1.

Does this allow us to consider oo as a constant and if so what type?
- in the Min-Plus [or Tropical] Algebra sytem, oo [or +oo] is used as the MAX constant.
- in Max-Plus Algebra -oo is used as the MIN constant.
- These algebras are extensions of game theory.

Does this mean that 2 is 'half-way' between 1 and oo?
- in a proportional rather than unit number line, indeed 2 is 'half-way' between 1 and oo due to reciprocity.

Congratulations on making a rather elite blog roll at 'MoonshineMath'.

Tommaso's post is very exciting, a new baryon! With the troubles to LHC, Tevatron is becoming the little engine that could.
