How to Graph Badly or What NOT to Do

“Chartjunk” is Edward Tufte’s term for extraneous features that add nothing to the information content of a graph. The worst collections of chartjunk are illustrations in newspapers and non-technical magazines. These figures are drawn by professional artists who are art-school graduates. To them, aesthetic beauty or visual interest is more important than statistics or the shape of a transcenden...

Paediatricians did not have duty of care to patient's mother.

Heroin users should, in certain circumstances, be able to get the drug on prescription from their GP, a Home Office strategy on tackling drug misuse has recommended. The move recognises that not all users find that methadone, the commonly prescribed substitute, works. For some users, it may be better, initially at least, to prescribe heroin, but then gradually move on to methadone. The announce...

Robots That Do Not Avoid Obstacles

The motion planning problem is a fundamental problem in robotics, so that every autonomous robot should be able to deal with it. A number of solutions have been proposed and a probabilistic one seems to be quite reasonable. However, here we propose a more adoptive solution that uses fuzzy set theory and we expose this solution next to a sort survey on the recent theory of soft robots, for a fut...

Simple Waves Do Not Avoid Eigenvalue Crossings

General one-parameter families of matrices avoid eigenvalue crossings. It is shown that the matrices associated with the simple waves of nonlinear systems of conservation laws do not obey this rule: a subset of simple waves with nonzero measure has crossing eigenvalues. © 2009 Wiley Periodicals, Inc.
