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

Why is Google cool, but Elsevier is not?

Elsevier-bashing has become a sport among researchers.  The company is singled out, among publishers of research journals, perhaps because it is the largest.  We might as well use Elsevier as a representative of the publishers, and hard-working people at Elsevier should not be offended. 

A common point of contention is that Elsevier makes too much money.  This is odd, given that many other companies make far more money, and that money symbolizes success in many cultures.  So making money, by itself,  should not be the reason that upsets researchers.

Nice Tips for Google Search Engine

In the current time computer and internet helps to everyone
in their daily routine. Thousand of people take help from search engine for
getting knowledge from internet per day. Mostly people use Google one of the
biggest search engine in the internet. As a Google user, you must aware about
the speed and accuracy of Google Search. How exactly Google search for the
particular word and give the right results in the front of the user. No doubt
Google is one of the most powerful search engines, and there is millions of
