Moebius transformations

Michael Brenner has just pointed out to me this video of the Moebius transformations.

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?"

4 billion years evolution in 8 min.

Recently I saw an animation
named “The inner life of the cell”, which was made by Howard Hughes Medical Institute and Harvard University Biovision. It can be watched online only:

UC Berkeley shows the class video at youtube!

As the mit show the OCW, the berkeley relases the class video at youtube, which could benefit the students all over the world. Enjoy it!  

A fluid flow video

I just remembered another video that I had seen some time ago.  Many of you have probably seen it but here it is for those who have not. (The original page where I found it is

Prof. Pat McMurtry's explanation is:

Eigenmodes of a square plate

The following video is a nice depiction of how the eigenmodes of a plate change with increasing forcing frequency.

An interesting coupling

A video that shows how some common couplings work. It's an advertisement but interesting nevertheless.  Does anyone know how the Thomson coupling works and what its main drawbacks are? It seems a bit complex and will probably have a higher rate of failure than simpler geometries - but maybe not?

IBM Airgap Microprocessors enabled by self assembly (Video)

An earlier post by Xiaohu Liu reported IBM's latest progress in microprocessors. IBM has figured out how to control and perfect the self assembly process to create trillions of tiny, nano-sized holes across a chip, which speed electrons that flow across wires inside the chip and reduce the power consumed by 15 percent.The following short video may help us understand a little bit more about the new technology. More videos, audio and images on this are available here (free, but registration needed)

I came across this video of a fluid phenomenon today. I have no clue what caused it. If you know something about it, please explain to us.

About a year ago, Zak Stone introduced me to YouTube with this video titled amazing liquid. I wonder how much of this behavior is understood. There must be a lot of fantastic videos of mechanical phenomena on YouTube. Perhaps we can embed them in iMechanica, and comment on them. Teng Li has provided an instruction of how to embed videos. You can check out a few other interesting videos in iMechanica video channel.

The comings and goings in a cell

Update 23 March 2007.  This wonderful educational video has now been removed from YouTube because it violates copyright.  What a pity!

Andre of Biocurious has just pointed out this terrific animation of the dynamics inside a cell. It brings many pages of textbook to life. Delightful. I've just followed Teng Li's instruction to embed the YouTube video below.

Movie of an expanding ring experiment

I have posted a movie showing a ring expansion experiment. A thin aluminum ring is made to expand through electromagnetic interaction at strain rates of about 10^4 per second. As the strain increases, numerous necks and fragments appear.

A pool filled with non-newtonian fluid

They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid. Video was recorded at Barcelona, Spain.

MechTube - applied mechanics outreach for children

Hello everyone,

Professor Suo suggested that I share this speculative idea that I once posted on Applied Mechanics News here on iMechanica!

In the future, we would like to reach out to children as early as their elementary school years to get them excited about topics drawn from Applied Mechanics. One approach to this goal takes inspiration from the successful "Le main a la pate", or "hands-in-dough", program in France ( ), but extends the idea of hands-on science to take advantage of the internet.

Gecko, Spiderman and Climbing Robot (Video)

I am at Boston for MRS 2006 Fall meeting this week, where I met a real "spiderman" at the poster session tonight. I'd like to share with you the following videos which were posted at YouTube by the "spiderman" himself, Mr. Jose Berengueres at Tokyo Instititute of Technology.

Mr. "Spiderman" also has posted a video on fasting climbing robot.

How to post a video?

Sometimes a video can be more convenient and effective than words on delivering a message. Now you can embed videos in your post in iMechanica. As a demonstration, I first embed a video below I made previously on how to make hyperlinks in your post. If you're interested in posting a video in iMechanica, read the following instructions:

How to embed a video in your post?
Step 1: Sign up a free account at, a website you can share videos online. Upon sign up, you can upload videos to YouTube. Follow the easy directions there. Of course you may want to read copyright tips of YouTube before uploading.
Step 2: Once uploaded, your video will have a Unique URL. You can always provide a hyperlink of the video in your post. To directly embed the video into a post, you need to use the html code automatically generated by YouTube, which you can easily find below the unique URL in the video information. Copy the entire html code.
Step 3: Since the current setting of the default text editor of iMechanica (those MS-word-type buttons above the textbox, called TinyMCE) does not support video yet, you need to turn it off and just use plain html. To turn off TinyMCE, click "my account" on the left sidebar, then click "edit" tab. Below "Account information" box, find "TinyMCE rich-text settings" and click it to expand the box. In the Default state, it shows "true" (means TinyMCE is on). Click the drop-down list and choose "false" . Scroll down to the bottom and click "Submit". Now TinyMCE is turned off.
Step 4: Start to post a new entry. Now you should see a Body textbox without any buttons. Paste the YouTube html code into the box. You can add any description above or below the code. If you want, you can also use any html editor to prepare your post and copy/paste the entire html file into the box.
Step 5: Preview your post then submit. Now all iMech users can view your video without leaving your post!
Of course, you can always turn TinyMCE back on by repeating Step 3.
We're still improving the video function in iMechanica. If you have any creative ideas to better achieve such a function, welcome to leave your comment below.
Enjoy vlogging in iMech.

Video Demo: How to make hyperlinks in your post?

In a recent post, Zhigang Suo explains how to add hyperlinks in your post. We all understand how hard to write an instruction for a simple operation, so we should appreciate Dr. Suo's every effort trying to be elucidative.

If you prefer a visualized instruction, click here to watch a video demonstration on how to make a post in your blog at iMechanica, and how to add a hyperlink in your post.
