Hidden by Time

30 minutes

In a world of motion, many events simply happen too fast to be seen with the unaided eye. With the aid of high-speed cameras, physical events which normally go unnoticed come to life to produce extraordinary sights. High-speed images reveal the awe and wonder of the physical world and provide an intriguing introduction to the study of physics. Hidden by Time is a collection of numerous physical events captured with high-speed cameras for classroom study. The program is comprised of high-speed motion events as well as high-speed still images.

High-Speed Motion Events (Approximately 30 Minutes)
Imaging of high-speed motion events was accomplished using a recently developed high-speed digital camera operating at 1000 and 2000 frames/sec; shutter speed of 0.04 milliseconds. Contained in the program are over 70 high-speed sequences involving impacts, collisions, and fluid behaviours.

High-Speed Still Images (50 Images)
Included in the collection of high-speed stills are over 20 classic images produced by Dr. Harold Edgerton, distinguished for his pioneering work in high-speed photography. Other high-speed still images were produced by Charles Miller, Massachusetts Institute of Technology; and Loren Winters, North Carolina School of Science and Mathematics.
