A new theory of stress?

I was browsing the discussion page for Stress in Wikipedia when I came upon this interesting comment:

Schwarzenegger Says He Would Accept Obama Appointment

Melanie Trottman reports on the presidential race.

Guests on the Sunday newsmaker shows, including California Gov. Arnold Schwarzenegger and John McCain adviser Carly Fiorina, spotlighted energy and the economy and paid tribute to former White House press secretary Tony Snow.

So, What's It Gonna Be?

Teacher, Scientist, or Engineer

From thinking about the 'I'd Love to Change the World' discussion, I have concluded that my dilemma stems from the (basically) three career paths from which I can choose.

A teacher that can have a great deal of influence on a select number of other individuals' lives and can take great pride in helping others achieve their potential, and possibly make great contributions to society.

A scientist that can continue to explore the unexplained and hopefully discover something that could contribute to society.

How Many Friends Is Too Many? 5000? Then imechanica is too many!

How Many Friends Is Too Many?

One MySpace exec has even surprised himself by friending a potato. This particular russet has 2,965 friends.

Artificially High Read Counts

 

There has been some discussion about the low ratio of replies to reads on iMechanica.  While it's nice to think that a lot of people are reading our posts, I wonder how many of those 'reads' are really bots indexing the page.  For example, I posted a blog entry last night around 11:00 and nine hours later it says it has been read 45 times.  A couple of those can be attributed to me but I'm sure 40 real people have not read the post.  Add to this the fact that the post is already showing up in Google.

The Future of Meshless Methods

I joined imechanica almost a year ago and I've been frequently following its interesting discussions, even the most animated ones. I think that a place like this is ideal to foster the exchange of ideas in the scientific community;

Moreover it is fantastic as a simple student like me can interact and easily ask questions to the most important researcher in the field of mechanics.

Problems of researchers in third world and how IMECHANICA can help them (it is not money).

many researchers in industrial countries think the only problem of third world researchers is money but it is not true. I worked as a researcher for four years in one of this third world countries.

Earthquake in West China and lessons for us!

In Singapore, I have seen students who lost their relatives in last earthquake. I am very sorry about this, but I think there should be lessons for us in such disasters.  Is'nt any cheap and easy way to reinforce building in the face of earthquakes? I hope such disasters make researchers concentrate on such important topics.

A lack of heroes, a lack of open culture

One of the things that I've thought about often in relation to mechanics is:

National priorities

The research funding environment we are all experiencing is extremely frustrating, and has the potential for long-term damage to academics and the nation. You may be interested in reading the letter to the Wall Street Journal by two Nobel Prize winners, David Baltimore and Ahmed Zewail.

Grand Challenges For Engineering

The US National Academy of Engineering has published a list of Grand Challenges for Engineering. Ths US National Committee on Theoretical and Applied Mechanics is interested in developing a discussion on the implications of these Grand Challenges to the Mechanics community.

are there platforms similar to iMechanica? should we list them all?

I think it would be useful to collect a list of most useful sites, to start with iMechanica-look-alike.  Not exactly similar but a good site for CFD is http://www.cfd-online.com/.  This incidentally suggests us some "ways" to improve iMechanica.  (see my other blog PROPOSAL for iMechanica node/2996)

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:
