On the need for popular science articles by mechanicians
Recently, the Royal Society Science book prize shortlist was announced; though the shortlisted books cover psychology, evolution, biodiversity, medicine and neurobiology, none in the area of materials or mechanics made it to the list. Or, pick any Best American Science writing volume--there are hardly any articles about materials or mechanics that make it to these anthologies.

The 2007 Melosh Medalists
The 19th Annual Melosh Competition for the Best Student Paper in Finite Element Analysis was held last Friday, April 27, at ETH Zurich. Two medalists were selected this year from the six finalists. The 2007 Melosh Medalists are Vikram Gavini, from Caltech, and Michael Hain, from Leibniz University, Hannover.
weight function for finding out the stress Intensity factors
Good evening Everyone,
I have some confusion regarding reference frame and origin point while dealing with concept of weight function in fracture mechanics.
