President Obama on the Necessity of Science (video)

Obama spoke at the National Academy of Sciences on Apr. 27, 2009, in which he states his commitment to doubling of science funding and stem education. From his speech,

 "At such a difficult moment, there are those who say we cannot afford to invest in science, that support for research is somehow a luxury at moments defined by necessities.  I fundamentally disagree.  Science is more essential for our prosperity, our security, our health, our environment and our quality of life than it has ever been before."

An article on tenure-track

Stop Trying To Get Tenure and Start Trying To Enjoy Yourself

One of my junior colleagues forwarded the above article to me, and I read with interest. I think it could also resonate the interest of many people here in iMechanica. I welcome your comments, especially from our been-there done-that tenured colleagues.

Effects of grain boundary adhesion and grain size on ductility of thin metal films on polymer substrates

We study the effects of grain boundary adhesion and grain size on the ductility of thin metal films well bonded to polymer substrates, using finite element method. It is shown that the ductility of polymer-supported metal films increases approximately linearly as the grain boundary adhesion increases, and as the grain size decreases. A rule-of-thumb estimate of the ductility of polymer-supported metal films agrees well with the simulation results.

iMechanica back on service

Dear fellow iMechanicians:

After some technical problems over the past weekend, iMechanica is now back on full service. We apologize for any inconvenience this may cause and thank for your patience.

We are particularly grateful to Ms. Lesley Lam in OIT of Harvard School of Engineering and Applied Sciences for her prompt fix of the problem.

Making flexible metallic glasses

Well-known for its high yield strength, metallic glass often suffers from its low ductility and intrinsic brittleness, as discussed in a recent iMech jClub theme on plasticity and failure in metallic glasses led by

Mechanics of microtubule buckling in living cells

As the most rigid cytoskeletal filaments, microtubules bear compressive forces in living cells, balancing the tensile forces within the cytoskeleton to maintain the cell shape. It is often observed that, in living cells, microtubules under compression severely buckle into short wavelengths. By contrast, when compressed, isolated microtubules in vitro buckle into single long-wavelength arcs. The critical buckling force of the microtubules in vitro is two orders of magnitude lower than that of the microtubules in living cells.

Everything is miscellaneous (Video)

While preparing a talk on iMechanica , I came across the following video "Information R/evolution" by Michael Wesch, an assistant professor of anthropology at Kansas State University.  This thought provoking video echoes a recent comment on "The future of knowledge?"

Enjoy!
