Swinging Pendulum (for High School)
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.

Oricalco - thermal shape memory fabric
The first orthogonal weaving example of Nitinol. The 'Thermal Shape Memory Alloy' is characterized by its extraordinary ability to recover any shape, pre-programmed, upon heating. Until today this light weight alloy with about 50% Titanium inside has been used in advanced sectors like space and recently in medical applications. Moreover this fabric is the first for which the shape memory alloy, named Nitinol, was weaved orthogonally that is to say that Oricalco is the first fabric with shape mem

"On the Night When the Levee Broke": William Cobb Remembers the 1927 Mississippi Flood
In spring 1927 it started raining in the Upper Midwest and, according to one observer, "it just never did stop." Torrential rains quickly filled the Mississippi's dozens of tributaries. On April 21, the supposedly impregnable levee system, maintained since 1879 by the Mississippi River Commission, sprang two leaks, or "crevasses" as they are known. Within days the Mississippi River levee system sustained forty more major crevasses in Arkansas, Mississippi, and Louisiana, unleashing a natural dis

Earth Rotation from Galileo Imagery: 3600 x Real-Time
This animation is one in a series created to show an accurate representation of the Earths rotation at different temporal resolutions. The animation is created from images taken by the Galileo spacecraft during a close pass of the Earth on December 11-12, 1990. The animations range from real-time, in which no rotation can be perceived, to 3600 times real-time, in which both the Earths rotation and cloud motion can bee seen. The series also includes an animation in which the Earths rotation has b

Molecular Classification - Prof. Chris Man (Part 2)
Recent advances in genomic and proteomic technologies have revolutionized our way of classifying diseases. These high-throughput technologies allow the development of powerful and multivariate classifiers to distinguish different diseases or tumors based on their molecular profiles. Molecular classification provides a new way to distinguish histologically similar but molecularly different types of tumors, and hence improves tumor diagnosis and prognosis. In this course, we introduce major concep
