Emerging Methods To Understand Mechanical Behavior at 2008 TMS Annual Meeting, New Orleans, LA, March 9-13, 2008
You are cordially invited to submit an abstract to the symposium on “Emerging Methods To Understand Mechanical Behavior” at 2008 TMS annual meeting, New Orleans, LA, March 9-13, 2008.
On the Possibility of Piezoelectric Nanocomposites without using Piezoelectric Materials
In a piezoelectric material an applied uniform strain can induce an electric polarization (or vice-versa). Crystallographic considerations restrict this technologically important property to non-centrosymmetric systems. It can be shown both mathematically and physically, that a non-uniform strain can potentially break the inversion symmetry and induce polarization even in non-piezoelectric dielectrics.
Using Windows Live Writer to write offline and publish to your blogs
When you use a desktop software, such as Microsoft Word, to write an entry and then paste it to iMechanica, the format often looks bad. Instead, you can use Windows Live Writer to write blog post offline. Installation takes about 5 minutes. The Live Writer has a remarkably clean interface, and is very easy to use.
August Workshop on Materials Characterization for Nanoscale Reliability
We invite you to participate in the upcoming Workshop on Materials Characterization for Nanoscale Reliability, to take place 14-16 August, 2007 at the University of Colorado in Boulder, Colorado. Details are posted at http://www.boulder.nist.gov/div853/Nanoscale_Reliability_workshop/index….
UG Course on Solid Mechanics
Given below is a sequence that might properly address the question of what to teach in the first (and the only) UG couse on strength of materials or solid mechanics.
0. Note: It's a mistake to believe that the contents for such a course can be covered in a linear fashion. Apply the spiral theory of knowledge and revisit certain concepts again and again: e.g., the concepts of stress, strain, fields, BV problems, theoretical structure, etc.
1. Introduction:
Google will videotape all Harvard classes and make them universally accessible
I wish that this thought had come to me earlier, so that I could have posted it on April First. No, I'm unaware of such a program. Instead, Harvard faculty have just emerged from a multi-year review of curriculum, and reaffirmed the commitment to liberal education, after voting out a president not too long ago.
