So, What is Mechanics? It seems that useful answers ought to depend on who you are talking to. If you are persuading your dean to hire a new faculty member in Mechanics, perhaps you’d like to point out promising research in one area or another. If you are explaining what you do for living at a dinner party, assuming that the party has heard enough of Iraq or intelligent design or entropy, perhaps you’d like to point out Mechanics helps to understand how a gecko climbs, or how an earthquake occurs, or how a computer chip fails, or how an airplane flies, or how the Twin Towers fell. You’d pick an example that you know well, keep it short, and be ready to answer obvious questions. If you are talking to an aspiring student, in addition to pointing out promising research areas and great applications, perhaps you’d like to point to a book that she’d gain an inspiring, yet technical, overview of our subject. A book similar to Courant’s What is Mathematics would be excellent. Such a book on Mechanics, however, has not been written.

Your aspiring student will not wait for The Great Book, and must have searched on the Internet. She’d most likely be disappointed of what she has found. The Google search of “Mechanics” may give her some idea, but hardly yields anything really useful for her purpose. It has been fashionable for some academics, along with parts of mainstream media, to dismiss the Web as a credible resource. Perhaps we have been unfair. We are mechanicians. It is up to us to tell the public what Mechanics is.

To this end, I have just started an entry of Applied Mechanics in the Wikipedia, with hyperlinks to existing entries (blue), and nonexisting ones (red). Like many entries in the Wikipedia, this one is a work in progress, and admittedly inadequate. Please feel free to delete, add, rearrange, and hyperlink.

(If you are new to the Wikipedia, you may want to read a previous entry in iMechanica, Wikipedia and Applied Mechanics. You may also want to read a few entries in the Wikipedia, such as , Nanotechnology, information technology, and Computer science.)

Let us hope that we will soon have enough material in Wikipedia and in iMechanica for anyone to learn about Mechanics, on any occasion and for any length of time. I'd be curious to learn what you think is Mechanics, and how we convey what we think to the public.
