PROPOSALS FOR IMECHANICA

Hello imechanica users: I launch a few ideas. Can we improve imechanica stealing ideas from successful web systems like google, amazon, wikipedia, myspace, youtube? Taking the best of the various worlds to improve our imechanica?

Why No New Einstein?!

My research topic is too different from string theory!. but i think this not so old opinion of Proff. Lee Smolin about world research system weaknesses is very beneficial to read. and have convincing arguments in neccessity of changes in this system. Read this. it is not related to string theory,

Grand challenges for engineering in the 21st century, and how they relate to mechanics

After making a list of the great engineering achievements of the 20th century, the National Academy of Engineering, of the United States, has recently described a list of the grand challenges for engineering in the 21st century (of no particular order):

How about "Rejecta Mechanica"?

A friend just forwarded me the following link:

http://math.rejecta.org/

quote:

"

Rejecta Mathematica is a new, open access, online journal that publishes only papers that have been rejected from peer-reviewed journals (or conferences with comparable review standards) in the mathematical sciences. We are currently seeking submissions for our inaugural issue.
About Rejecta Mathematica

My new blog!

This is the first scientific blog for me in English though I have had three others in Chinese. I hope it's a significant beginning for my new scientific stage! Communication with top scientists and openning my view are both important issues for me in future. To be a useful scientific dog is to do some innovational things!

iMechanica: 5000 registered users, 9.5 million web hits


Launched on 9 September 2006, iMechanica is the web of mechanics and mechanicians.  The mission of iMechanica is twofold:

Science, as some see it...

I came across some content I used to have on my webpage a long time ago.

http://www.ce.cmu.edu/~amita/webpage_misc.html

Hopefully it is inspirational for that bright, young, graduate student waiting in the wings to usher in the revolution that shows us how to solve some of the outstanding theoretical problems of solid mechanics that we seem to put off  e.g. concrete, quantitative methods for calculating time-dependent microstructure in plasticity and its effect on time-dependent macroscopic properties.....

The leaky pipeline

A new report has been published on the "leaky pipeline" question:

A persistent problem. Traditional gender roles hold back female scientists

The story behind the proof of Fermat's Last Theorem

When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.

The Future of Conference

Attending conferences is one of the essential professional activities for scientific researchers. Conferences take various forms, such as community-wide meetings (e.g., MRS meetings, ASME congress, APS meetings), and topic-focused meetings/workshops (e.g., Plasticity07, Gordon Research Conferences(GRC)).  While people have different preferences on the types of conference to attend (e.g., see a recent iMech poll initiated by Biswajit Banerjee ), here are some common positive driving forces to motivate one to attend a conference:

Introduction to Systems Biology

How does the cell know when to produce a protein? Why does it produce this protein? How does it produce this protein so accurately, in transcription, timing, and concentration? It is amazing that the cell functions as precisely as it needs to in response to various stimuli. What is more amazing is that the cell's actions are a result of stochastic processes.

Question: Is the local energy dictating dislocation emission constant for single crystal?

Hi everyone, in my size dependence study, I find the local energy dictating dislocation emission is almost constant for varied sized samples, in given directions of single crystal. I don't know this is an interesing finding, or just a common sense. Will you give me some suggestion, Thank you!

Power of iMechanica during job hunting

In July 2007, my friend of a consulting company contacted me for recruiting a computational mechanics engineer. I told him that all my graduate students found jobs, and there are not many mechanics students in our small department. So, I posted his ad at iMechanica. Only after one week, he asked me to withdraw this ad! Why?

iMechanica Poster

I created this one page poster for publicizing iMechanica, primarily in schools among students, where I think a lot of students are unaware of iMechanica. I hope I am not infringing on any copyright rules or negatively impacting iMechanica's image and sensitivities. Would it be okay to print this out and post it on notice boards in school? Also, please let me know if I can improve on the design or add/remove any components. I will resubmit the final version as a pdf for student volunteers to print (if it is acceptable).

Thanks for your time,
Dhruv

Mechanics in the news

Since I am an alum of the University of Minnesota, when I was a PhD student I lived only a few blocks from the site of yesterday's catastrophic bridge collapse in Minneapolis.  The statics analysis of a truss is almost the first thing learned by every undergraduate engineering student, and appears to be relevant here.  It is interesting to see words like "fatigue crack" and "vibrations" in the news .  In light of such events,

Sci & Engng Publication Output and the Research &Publication Environment in the US: NSF Reports

Within the last two weeks the US National Science Foundation (NSF) published not one but two studies on (a) the attitudes of scientists and engineers to the changing world of publication, and (b) the relative global productibity of US science & engineering as measured by journal publication.    

These are not dense 500 page reports, but short, readable (10-15 min.).  I think iMechanica readers will find them relevant and interesting:

CALLING ALL STUDENTS! (and everyone else)

Recently, Prof. Suo and several of us students have been discussing the possibility of increasing student presence and activity on iMechanica . With this in mind, two of us: Mahdi Kazemzadeh and I, have identified three important issues we would like to get your thoughts on. Please comment and let us know what you think, even if you are not a student. Also, if you wish to add any more issues you think we should look at, please post your thoughts in this regard as well.

Why do people become registered users of iMechanica?

The number of registered users of iMechanica is approaching 3000.  This sustained growth has been surprising to many, considering that iMechanica was launched less than a year ago, in September 2006, that iMechanica uses an off-the-shelf open-source software, Drupal, and that everyone can read everything without registration.  Why have so many people registered?  There might be many reasons, such as

hi all,

i would like to know how can i find the error in a heat transfer problem with the help of
