Some math for pi day
 
Today is often referred to as “Pi Day”, since in the United States and various other countries, the date March 14 is written as 3/14. Beyond those who write the date 14/3, there are a few who object to Pi Day for other reasons. For pedants who want to…

The Science of Why Many Don’t Believe Science

It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.

The theory of motivated reasoning builds on a key insight of modern neuroscience: Reasoning is actually suffused with emotion (or what researchers often call “affect”). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we’re aware of it. That shouldn’t be surprising: Evolution required us to react very quickly to stimuli in our environment. It’s a “basic human survival skill,” explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself.

Preliminary combination of results from +CMS Experiment and +LHCb Experiment confirms discovery

Last Friday, CMS and LHCb reported their individual results for the decay of B_s mesons (pronounced B-sub-s) into pairs of muons. Yesterday, both collaborations jointly presented a preliminary combination of their measurements at the EPS HEP conference. This preliminary analysis measures the rate of decay to be 2.9±0.7 x 10^–9, consistent with the predictions of the Standard Model; the significance of this observation is more than 5σ. A precise evaluation of the significance as well as a more detailed combination of the decay rates are in the works. In the meanwhile, this important discovery is yet another feather in the cap for the LHC, and is a testament to the excellent performance of both CMS and LHCb.

The combined results also show a slight excess in the data in the B^0→μμ channel, consistent between the two experiments, but it is not statistically significant.

The joint paper can be found here: http://cds.cern.ch/record/1564324
