God's Place In Fundamental Emergence

Emergence, for example emergent gravity, implies a lower stratum from which something emerges. “Fundamental emergence” is the idea that all can or must be described as emergent, without however there being a full explanation of lower layers. A lowest fund ...

Thank You America

Today I feel as American as I've ever felt. I've lived there for a while, and of course as a foreigner I have many things I love and many I hate about this remarkable country. But today, Americans electing Obama as President for four more years s ...

What Makes Particles Unstable?

A journalist I am following on twitter just posted the question in the title of this post. I felt bound to try and give an answer with as simple concepts as I found meaningful. So, what makes a unstable particle unstable? One answer is this: a particle is ...

Top Quark Mass: The Final Word From The Tevatron

The CDF and DZERO collaborations at the Fermilab Tevatron collider just saw published on Physical Review D (PRD 86, 092003) their final combination of their most recent and precise measurements of the mass of the top quark. This result, which is probably g ...

LHCb: Evidence For Rare Decay Bs To Dimuons

It has taken a while, but the rare decay of B_s mesons (particles composed of a bottom and an anti-strange quark) to muon pairs has finally been seen. The authors of the find-we cannot yet call it an observation given the scarce statistical significance of ...

Top Quark Results At HCP: Asymmetries

The Hadron Collider Physics symposium opened yesterday in Kyoto. I am not following the works very closely, but I did give a peek at today's talks, which were on the topic of top quark physics. ...

Higgs: New ATLAS And CMS Results

Today new results of Higgs searches have first been shown in Kyoto, at the Hadron Collider Physics conference. Let us see the CMS and ATLAS updates of their measurements in the ZZ-> 4 leptons final state, which constitutes the best signal-to-noise chann ...

CMS And ATLAS: Higgs To Tau Pairs!

Maybe more interesting than the just reported result of searches for the Higgs boson into four-lepton final states (ee, eμ, μμ) are the result presented by CMS and ATLAS on the searches for the Higgs decay into tau-lepton pairs. The reason for the interest ...

The hierarchy of objects

I present you my personal view on the hierarchy of objects that occur in nature. I only treat the lowest levels. A-- The lowest level is space that is formed by the number system of the RATIONAL quaternions. However, better make it an affine space (a spac ...
