Measurement

Playing in Galileo's Lab (part 1)

It was 8:45 AM in Florence and I was waiting for one of the highlights of my 2012 Italian family vacation the chance to see the original creations for one of the greatest minds of the 17th century, Galileo. Take a tour of the Galileo Museum with me and see the classic Physics demos as they were in the 1600's.

With respect to this globe, how far is 200 miles? Well, look here (pointing to the globe) New York City to Boston is about 200 miles. With respect to this globe, that's about this far. (Holding up his thumb and fore finger barely apart.) Then he asked, "How far out does the Space Shuttle orbit?" Answers are offered all around; 230 miles, 200 miles, 180 miles...

Extending Our Senses: Indirect Measurement

Posted on September 1, 2003 by Chris Chiaverina

Everything we experience comes to us through our five senses—sight, hearing, touch, smell and taste. While our senses are truly amazing, most of what goes on around us occurs unnoticed. Since we can only see a small range of the electromagnetic spectrum as visible light, we can be in the vicinity of a radio-transmitting tower radiating 50,000watts of power and be totally unaware of its presence.
