Science, as some see it...
I came across some content I used to have on my webpage a long time ago.

At the 2007 ASME Congress, in Seattle, Professor Wing Kam Liu won the 2007 Robert Henry Thurston Lecture Award. Wing Kam was a past chair of the Applied Mechanics Division, and has made seminal contributions in the field of computational mechanics.
I'm very interested in the choice of the finite element spaces for elasticity. I want to choose elements for the stress and the velocity, I was suggested to use piecewise constant for the stress and piecewise linear for the velocities to satisfy the Babuska-Brezzi condition. Is that right? I've heard that I can't use only 6 components for the stress in this way, but I must add some additional constraint to enforce its simmetry. I'm looking for additional documentation, but I can't find any. Has someone got any suggestion? Thanks.
A new report has been published on the "leaky pipeline" question:
A persistent problem. Traditional gender roles hold back female scientists
Rather than scratching heads when faced with a seemingly impossible contradiction in a job, engineers could do worse than apply the Triz theory.
There has been quite a buzz around Triz, the Russian theory of problem solving, for some time. Since it was fully refined in the mid-1980s its use has been slowly spreading as word gets round, much like the increasing popularity of a political movement.

In order to try and get some of the vast store of engineering information we're sitting on out to a wider audience we've created a number of occasional subject guides for engineers and students. The aim is to highlight sources of information available from our Library and the Institution itself.
You can see an example of one of these (for the aerospace industry) here, from which you can browse to a whole host of others.

The official brochure will be available shortly.

What is the relationship between hardness and elastic modulus? The higher hardness, the higher elastic modulus? My understanding is that hardness is a local mechanical property, and
elastic modulus is an averaged global mechanical property. Am I right about this?
