# s-phys: the beryllium anomaly, hypothesis of a fifth force

<< Earlier this year, an experiment in Hungary reported very unusual behavior in the decays of beryllium-8 nuclei. The experimental collaboration suggested that their results may come from the effects of a new force of nature. If confirmed, this would have far-reaching consequences on fundamental physics including grand unification, dark matter and the experimental strategy for pushing the frontier of human knowledge. >>

FonT: a differenza del tecnologo e della gran parte delle altre professioni (a parte l'atto artistico spontaneo, improvvisato), per chi si occupa di ricerca scientifica in qualsiasi ambito disciplinare la comparsa (e la dimostrazione sperimentale) di una "anomalia" e' da considerare sempre e in ogni caso evento ricco di informazione, percio' evento di primaria importanza, da trattare possibilmente senza pregiudizi;  in questo aspetto (fondamentale) l'umano nomade (il boscimane ad es.) e lo "scientist" sono nei fatti piu' vicini di quanto si creda ... una sorta di "cerchio" che si chiude ...

# e-sec: a priori cracked; 'verifiable computing' vs chip manufacturing

<< Medical devices, public infrastructure and voting machines, as well as financial, military and government electronics could all be compromised long before their first use if backdoors were added to their chips during the manufacturing process.  The issue could affect CPUs, GPUs and motherboards, but also storage and memory components. These days we're seeing more companies employ cryptographic signing for their software to ensure that the code delivered to the users is identical what was written by the vendors (although not all companies are taking this to heart yet). A similar validation process is needed for hardware to ensure its integrity. >>

<< Proposed by futurist John Smart, the theory suggests that technological civilizations — and the Fermi paradox assumes there would be many by now — don’t colonize outer space (and thus flood the cosmos with signatures we could easily find). Instead, they move toward inner space by building vast digital realities on computers much smaller than we can detect. >>
