A new perspective on MOND

New constraints on MOND from galaxy clusters

We revisit the application of Modified Newtonian Dynamics (MOND) to galaxy clusters. We confront the high quality X-ray data for eight clusters of galaxies observed by the XMM-Newton satellite with the predictions of MOND. We obtain ratios of the Newtonian dynamical mass to the MOND mass of Md/Mm = 1.09 ± 0.08 at r ∼ 0.1 Rvir increasing to Md/Mm = 1.57± 0.24 in the outer parts (i.e r ∼ 0.5 Rvir...

A new perspective on evolution.

A new perspective on emotions.

This paper reviews the recent history of the study of human emotions in psychology and traces the factors that have been responsible for a remarkable increase of interest in emotions, especially in human development. In particular, it traces the rise of the study of emotions as regulators of human behavior. A particularly clear and powerful illustration of the regulatory role of emotional expre...
