  • Remarks about the 144 GeV bump found in CDF data analysis

    The first comments follow the discussion at this blog link: http://blogs.discovermagazine.com/cosmicvariance/2011/04/06/anomalies-at-fermilab/comment-page-1/#comment-158561 A few things are wrong here with some remarks (and misunderstanding) I point out one misunderstanding: the bump is a tail moving slowly as per Monte Carlo. “The bump is clearly a Gaussian so we can’t say it’s a tail that’s moving slowly because…

  • Monte Carlo: we expect snakes here.

    Monte Carlo: we expect snakes here. 1 Sigma: Isn’t that a tail? 2 Sigma: yes that’s a tail, but is that a snake? 3 sigma: thats definitely the tail, but did you see the hood? 4 Sigma: that’s a rattle snake. 5 Sigma: it bites you, you die.

  • How Radio-active are cigarettes?

    Units: 37 GBq = 37×10^9Bq = 1 Curie Radioactivity of Pb(210) and Po(210) Lead 210, 22.3 years, 207.2 g/mol… Q = 0.064 MeV (beta) Polonium, 137.376 days, 210 g/mol… Q = 5.407 MeV (alpha) Let’s assume the amount of lead and Po to be 0.5 micro-gram each in 1 cigarette. SO (0.5/207.2)x10^(-6) mol of Pb…

  • The radioactivity of banana (I did this for cigarettes also)

    a simple radio active decay uses the ideas of quantum mechanics

  • Life time of particles and Time dilation

    SO a muon which has a life time of 2 micro seconds moving at a speed of 3, 5ths of the speed of light would live for 2.5 micro seconds because time would dilate, that is, the life time for the muon observed by someone when it moves fast (apparent life time) will be more.
