Nowadays, we often use the tools of computational analysis in engineering design. For the results of such analyses to be believable, the tools that are used have to pass rigorous tests. There are two categories of tests involved:

As a moderator here on iMechanica, I have deleted a few posts recently that were clearly spam. As iMechanica grows and becomes more visible within the mechanics community and the broader internet community, we can expect the frequency of these kinds of posts to increase.

The U. S. National Congress on Computational Mechanics will be held in San Francisco, CA July 23-26 2007 (see link for conference below). As part of the symposium, "Modeling and Simulation of Nano Materials and Mechanics", an invited session discussing stress evolution at the nanoscale will be held. This session will foster discussion of outstanding computational challenges to understanding and predicting stress evolution during growth of materials at the nanometer length scale. Registration information for the meeting can be found via the link below.

An earlier post by Xiaohu Liu reported IBM's latest progress in microprocessors. IBM has figured out how to control and perfect the self assembly process to create trillions of tiny, nano-sized holes across a chip, which speed electrons that flow across wires inside the chip and reduce the power consumed by 15 percent.The following short video may help us understand a little bit more about the new technology. More videos, audio and images on this are available here (free, but registration needed)
Enjoy.

An interesting blog discussion on the disappearance of fundamentals from teaching in Universities was brought to my attention.  It serves as an interesting reminder that we who are educators in the University system must be ever vigilent in planning mechanics curricula and changes to curriculum.  Should we be offering courses in the area of this month's jClub, "Nanomechanics"?  Should we drop classical courses that have stopped being interesting to the majority of students (and thus attract low numbers)?  Should we educate students explicitly in biomechanics without providing them a classical mechanics background?  These are the questions we are likely to face in the next few years as change continues to sweep across the university system, especialy in the US but elsewhere as well.  I believe that we as a community have a responsibility here to ensure that the high standards of the discipline are maintained through teaching of fundamentals and the passing along of these values to future generations!

On Wednesday morning, I received an email from Anastassia Paskaleva. She was unable to create an account on iMechanica, because CAPTCHA kept telling her that she typed the letters wrong. Lesley Lam, iMechanicia user number 1, has just fixed the problem. Now new users can register once more. We apologize for the inconvenience that this problem might have caused you, and thank Anastassia for letting us know the problem.
