Actinides: How well do we know their stellar production?

The reliable evaluation of the r-process production of the actinides and careful estimates of the uncertainties affecting these predictions are key ingredients especially in nucleo-cosmochronology studies based on the analysis of very metal-poor stars or on the composition of meteorites. This type of information is also required in order to make the best possible use of future high precision da...

How Well Do We Know Bernoulli?

Näıve Bayes probabilistic models are widely used in text categorization because of their efficient model training and good empirical results. Bayesian classifiers face a common issue called data sparsity problem which makes an adequate estimation of probabilities a difficult task. Therefore, smoothing techniques are needed in order to adjust the maximum likelihood estimators. In this preliminar...

Superior Capsule Reconstruction: What Do We Know?

The management of irreparable rotator cuff tears remains challenging. Since its introduction by Mihata in 2012, superiorcapsule reconstruction (SCR) has grown in popularity at an astonishingly rapid rate. The aim of this article is to providea comprehensive review of the available literature, in order to highlight what has so far been published on SCR,covering all aspects including biomechanica...

Do We Know What We Do not Know? A Response to Celine Bonnet

How do we know that we know what we know?

How Science Works’ is now the focus of the national science specifications in English schools. This article is a brief introduction to the philosophy of science from the Greeks to the present day that underpins this notion. From September 2006, the emphasis for teaching science at GCSE is on ‘How Science Works’. This focus will also shape the revisions of the AS and A2 specifications from Septe...
