A Marvellous Pool

Richardson's Marvellous Forecast

Archaic man meets a marvellous automaton: posthumanism, social robots, archetypes.

Posthumanism is associated with critical explorations of how new technologies are rewriting our understanding of what it means to be human and how they might alter human existence itself. Intersections with analytical psychology vary depending on which technologies are held in focus. Social robotics promises to populate everyday settings with entities that have populated the imagination for mil...

Leonardo da Vinci. The marvellous works of nature and man

The title of this beautifully-produced book gives the key to its content. Giambattista Venturi in 1797 was the first to emphasize the scientific importance of Leonardo's studies of the works of nature. During the following century, there was a vague, exaggerated admiration of Leonardo's achievements in science. However, the artistic side of Leonardo's activity, though so small in quantity, was ...

Phosphoramidites: marvellous ligands in catalytic asymmetric conjugate addition.

The development of an efficient catalytic system for enantioselective carbon-carbon bond formation by 1,4-addition of organometallic reagents (organolithium, Grignard, and organozinc reagents) to enones is a major challenge in organic synthesis. This Account presents the breakthrough realized in this field using chiral phosphoramidite ligands for copper-catalyzed dialkylzinc additions. Applicat...

To pool, or not to pool?

Let's start with the most familiar context for pooling data (at least to students in introductory courses in statistics), viz., the pooling of sample variances in a t test of the significance of the difference between two independent sample means. The null hypothesis to be tested is that the means of two populations are equal (the populations from which the respective samples have been randomly...
