The goal of Mapping is to put mapping tools, from sextants to software, in the hands of visitors and let them explore the science and technology of mapping. From compasses to Google Earth, Mapping will show the developments in map making and the diversity of data that can be incorporated. Mapping will showcase a myriad of maps, such as; digital, printed, relief, overlays, topographical and many others. It will also explore the tools and techniques associated with mapping spanning from surveying to satellite. Ultimately, this exhibition will enable visitors to develop a deeper insight of how multifaceted the science of mapping is. Mapping is designed to be hands-on, encouraging engagement from our visitors and enabling them to experience the thrill of making discoveries.

Using sound waves to measure distance - in this case your height.

In this exhibit, an ultrasonic transmitter/receiver bounces sound waves off the top of your head and times how long it takes the echo to return. Since sound travels at a constant speed (13,536 inches per second), the microprocessor in the exhibit can convert the measured time into a distance measurement - your height.

If the top of your head is twenty inches away from the transducer, the ultrasonic signal takes less than three thousandths of a second to make the round trip.

One of the marvels of modern microprocessor technology is the speed at which signals of all sorts are produced and processed. Ultrasonic sound waves are at frequencies above the range of human hearing which tops out at about 20,000 cycles per second. Ultrasonic devices are used in proximity, liquid flow and measurement devices as well as medical imaging instruments.

This exhibit was designed and built by Neal Martini.
