Analysis watchmakersShould you trust your financial advisor? Pseudo-mathematics and financial charlatanism
Your financial advisor calls you to suggest a new investment scheme. Drawing on 20 years of data, he/she asks: If you had invested according to this scheme in the past, which portfolio would have been the best? His/Her computer assembled thousands of simulated portfolios and calculated for each one a measure of return on risk. Out of this calculation, your advisor has chosen the "optimal" portfolio, which he/she recommends, noting it is based on sound mathematical methods. Should you i...

I particularly liked the part where they wanted $3 billion from Google. That doesn't make them look crazy at all. Nope. Not at all. The thing is, they have legitimate complaints, as Kevin Rose very generously acknowledged. I wish that they were going about it in a way designed to produce positive change, rather than negative attention.

Off mass-shell: Pythagoras to the LHC, via Einstein and Feynman
Jon Butterworth: When a particle physicist describes something as "off mass-shell", they could be referring to a bit of quantum mechanics, or denouncing an unrealistic budget. Either way, it's a bit of jargon connecting Pythagoras to the LHC, via Einstein and Feynman

Overcoming structural uncertainty in computer models
A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for a particular problem can rarely be defined with certainty. Scientists have now offered a method to incorporate judgments into a model about structural uncertainty that results from building an 'incorrect' model.
