The Quote of the Week: Lyons on Single Event Probabilities

The Quote of the Week: Lyons on Single Event Probabilities

Jan 10 2013 | comment(s)

"Given that a repeated series of trials is required, frequentists are unable to assign probabilities to single events. Thus, with regard to whether it was raining in Manchester yesterday, there is no way of creating a large number of `yesterdays' in order to determine the probability. Frequentists would say that, even though they might not know, in actual fact it either was raining or it wasn't, and so this is not a matter for assigning a probability. And the same remains true even if we replace `Manchester' by `the Sahara Desert'.

Baksan: No Dark Matter In A 24 Year Long Exposure Of The Sun!

Jan 08 2013 | comment(s)

I just read with interest and awe the nice article appeared today in the arxiv about the search for dark matter annihilation in the sun's core by the Baksan Underground Scintillator Telescope (BUST), a facility operating since December 1978 (!) in the Caucasian valley of Baksan.

Two Peaks, Three Bets

I am glad to see that the Higgs signal we have discovered last July continues to raise the interest of well-learned laypersons around the world. The confirmation this time comes from the fact that three readers of this blog have decided to challenge my bet that the two signals found by ATLAS in the gamma-gamma and ZZ decay modes, which presently have a discrepant measured mass, are no hint of two distinct resonances, but rather a systematic effect.

Excluding New Particles: The Nuts And Bolts

Jan 02 2013 | comment(s)

Occasional readers of this blog, I reckon, have time and again been left wondering what is the matter with these lower mass limits on new particles that physicists so copiously produce with their subnuclear physics experiments. How are they determined ? Why always lower mass limits and (almost) never upper limits ? And why do we care ?

It is with some delay that I decide to write about Aldo here. The reason is simply that after a house move I still have not been reconnected to the internet at home, and my absence from work for christmas holidays makes things even harder, and my presence online a sporadic break rather than a constant of motion.
Highlights From The Città Di Padova Chess Tournament

Highlights From The Città Di Padova Chess Tournament

Dec 26 2012 | comment(s)

Last week I spent my time playing in a strong chess tournament in Padova. The tournament had 50 participants, among which 11 grandmasters and 10 international masters, and was definitely the strongest event I took part in during my amateur chess career.
