Why Can’t Humans Walk on Water and Climb Walls with their Fingertips like Spiders?

Dr. Rafael Davalos

April 10, 2010
An interactive session led by Dr. Rafael Davalos 

Assistant Professor in Biomedical Engineering at Virginia Tech

Different forces are dominant at different length scales. This is why some bugs can walk on water and mammals can only be so small. This talk will discuss some of the basic physics of scaling laws. We will talk about the role of these laws in nature and how engineers and scientists use these principles when designing and creating microsystems and nanotechnology.

Dr. Rafael Davalos is an Assistant Professor in Biomedical Engineering at Virginia Tech. He has a joint appointment with the Virginia Tech- Wake Forest University School of Biomedical Engineering and Sciences. His research interests includes biomedical microdevices and cancer detection and treatment.

April 2010 - Hands-On Exhibits

After each KTU interactive session the students are escorted by their parents to have lunch and then to the hands-on portion of the event. There the students enjoy the experience of interacting with various exhibits from the Virginia Tech community.
