W find that experienced poker players typically change their style of play after winning or losing a big pot—most notably, playing less cautiously after a big loss, evidently hoping for lucky cards that will erase their loss. This finding is consistent with Kahneman and Tversky’s (Kahneman, D., A. Tversky. 1979. Prospect theory: An analysis of decision under risk. Econometrica 47(2) 263–292) br...

The paper " Big Bang Nucleosynthesis and Active-Sterile Neutrino Mixing: Evidence for Maximal ν µ ↔ ν τ Mixing in Super Kamiokande? " by X. Shi and G. M. Fuller (astro-ph/9810075) discusses the cosmological implications of the ν µ → ν s solution to the atmospheric neutrino anomaly. It incorrectly concludes that a lower bound on the ν τ mass of 15 eV is needed in order for the ν µ → ν s oscillat...

disease by 30%," which sits uneasily with the report's own acceptance that the Medical Research Council's hypertension trial found "no significant effect on heart disease" from the reduction of mild to moderate hypertension. To have maximum impact such reports should surely offer no unprotected flanks to their critics and should concentrate on limited and attainable targets for which unimpeacha...

I review standard big bang nucleosynthesis and some versions of nonstandard BBN. The abundances of the primordial isotopes D, He-3, and Li-7 produced in standard BBN can be calculated as a function of the baryon density with an accuracy of about 10%. For He-4 the accuracy is better than 1%. The calculated abundances agree fairly well with observations, but the baryon density of the universe can...

The first theoretical evidence for the Big Bang came from Alexander Friedmann in 1922, when he showed that Albert Einstein’s theory of general relativity predicted that the universe was either expanding or contracting. Einstein was so upset with this result that he introduced a cosmological constant into his theory which would make the universe static. Later he said that this was his biggest bl...

NIBCO, Inc., a mid-sized manufacturer of valves and pipe fittings headquartered in the U.S. with $460 million annual revenues, implemented SAP R/3 across its 10 plants and 4 new distribution centers with a Big Bang approach in December 1997. NIBCO management agreed with the Boston Consulting Group recommendation to "cut loose" from its existing legacy systems and replace them with common, integ...

Due to the accelerated expansion of universe, possibility formation singularities has changed from classical Big Bang and Crunch include a number new scenarios. In recent papers it been shown that such may appear in inflationary cosmological models with fractional power scalar field potential. this paper we enlarge analysis by use generalised expansions their Hubble order describe all possible ...
